RF-30 Mill Drill Restoration - Forme Industrious

- Опубліковано 30 січ 2020
- This has to be my dirtiest project. Well, in this video I restore a Herless RF-30 Mill Drill. It was gifted to me by a gentleman down in Adelaide, South Australia. I just had to pay for the freight to get it to Townsville. This machine needed a lot of work to bring it back to its former glory, well as near to it as I can. The motor was 415 Volt 3 Phase and I don't have that power in my shed. An option was to install a VFD but those can be expensive for a good one and really I think it would have added unnecessary complexity......ok I'm making excuses....they are just too expensive. I bought a single phase 1.5 KW motor from Ebay with the only issue being the shaft diameter being 24mm and the pulley was 22 mm. I was missing the Spindle Collet (MT3) and Draw bar and one of the Quill handles. The Milling table was badly rusted and pecked. Not a problem to me. Well, now that it is all cleaned up and working I'm very happy with it. Over time I will buy the tooling needed to get the most out of this machine.
Well I hope you enjoyed the video and thanks for watching.
Regards

This press has worked like a charm for my projects ua-cam.com/users/postUgkxajoEbapTfqWaadnqb04h6U576yxXp-FE . I didn't even secure it to my table top, mainly due to the fact that I was using a 15 lbs drill vise. It's not flimsy at all as to what others have claimed it to be. Make sure the locking nuts and levers are secured and there won't be any issues with light pressure and patience. I was able to drill through aluminum, plastic, and steel (steel took a while) with no problems at all. Yeah it took a little longer than a regular drill press, but I don't have the space OR the money for one.The instruction manual was worthless, but luckily assembling the press was intuitive. However, the manual would be good for ordering replacement parts if needed. There is a nice breakdown of the parts that are included in the kit. Before ordering, make sure it is compatible with your unit, it is clearly stated what models the press is compatible with.This was an excellent purchase for $40!!
I learned an awesome tip a few years back from a friend; get yourself one of those basic cheap FoodSaver (that’s the main brand in the US anyway) vacuum sealers. Next time you need to pack a bearing, cover it in a good amount of grease, pop it in a vacuum bag and run it through the machine. When all the air comes out it pulls all of that grease down into the bearing. Fast, easier and a hell of a lot less messy. Friend does that for spare wheel bearings when he goes to the race track. Aside from being easier it also doubles as keeping any spare bearings sealed from dust/debris in a nice neat package 👍🏻. Awesome video as always sir! Cheers from Arizona!
What a great tip! Thank you Danny, very much appreciated. All the best!
Nice to see people still know how us old guys packed a baron correctly
Thanks Lloyd.
A simple but useful mod is to add some thin disk spring washers (Belville springs) to the spindle clamp. It allows constant drag on the spindle even when there is some wear where the clamping brake blocks contact it. You can still compress them down enough to lock the spindle when required but it stops some of the annoying rattle that results from leaving it too loose. I have eight of them in alternating directions on mine (0.035" thick a bit less than 1mm). It also allows you to have the clamp lever in a suitable position without it loosening under vibration.
Your keyway broaching with the lathe was genius.
Excellent job Scott. You can be sure that this will be a reference video for years for everyone that owns one of these mill drills. Thanks for the effort to make this.
Thanks Jim! I'm glad if it can help someone.
That bit with the chisel, ingenious. I'd have honestly never thought of it myself, I'd have been filing, gingerly, for hours.
Thanks Terry. It worked surprisingly well. Good thing it was Aluminium though. Steel would be much more difficult.
That was some amazing MacGyver work cutting that key way with the chisel. I'll have to remember that.
It did the trick, I've done dodgier stuff ;) Thank you!
30 wonderful minutes! Exceptional attention to detail! Could almost smell the grime! Great work!
I love the smell of old machinery grime first thing in the morning. Thanks again!!
Much respect, my friend. That was a huge job, and you did it thoroughly. Love your broaching tool solution! I am so glad to see that machine in your hands, put back into service. Thank you to whomever donated it to Scott.
Thank you! I was looking for a simple solution for the enlarging the keyway. Fortunately the Aluminium is nice and soft and I could get away with using the chisel. I was surprised how easy it was in the end. I was happy to mention the guys name however he wished to remain anonymous. He is thrilled to see it back in action.
Absolutely I fully agree Batti2323
@@ScottTurnerformeindustrious Lucky you didn't just put a VFD on it as I will explain.
FYI - I am an engineer with 30+ years in automation and I have installed and commissioned 100s of VSDs all all types of motors.
*1st* off the correct terminology these days is VSD (Variable Speed Drive). The old terms of VF, VFD, VVVF and others have been sent to the history bin for the simple reason that these days even basic drives can vary so many motor driving parameters and functions that its just inaccurate to call them anything other than VSD. If you tired an acronym that accurately describes all they can do it would be (in some cases) 100s of letters long. Circa 2010 I used a basic ABB 150 VSD on a fan [pushing air on a mine site. We did that for nothing more than the motor starting. That basic drive had more parameters and capabilities than many of the state of the art drives from the 90s. There was an incredible leap in motor control technology in the late 90s early 2000s. I have used some drives with in excess of 3,500 parameters.
Surprisingly some of the really high performance servo amps for robotics are also incredibly simple. Most of those vary nothing more than the torque output. Doing that accurately over the full speed range is the tricky bit.
*2nd* there is a huge misunderstanding that single phase VSDs operating at 240VAC input then output 415VAC to the motor. *THIS IS TOALLY UNTRUE.*
The way *ALL* VSD's work is they first convert the incoming AC into DC and then use a transistor pack to create the variable 3pahse output. There's no magical voltage increase in that process. *I have seen others make this basic mistake on UA-cam* and there is a simple fix.
In Australia many motors under 5kw and most under 2.2kW can be reconfigured. You can use them with 415VAC in DELTA where the 3 coils are arranged in a triangle (the Greek letter for D is a triangle). You can also use them with 240VAC in a STAR configuration where the 3 coils are arranged in a Y configuration. What you do need to consider is the POWER consumption. Not output but consumption which shows up as current. So you have to be carful that the cable to the motor is rated for the additional current. And yes engineers make that mistake way more often than they like to admit.
What you can do with many 3phase motors to retain the power output is reconfigure the motor from DELTA to STAR. If you look in the motor terminal box for a 3phase motor most actually have 6 terminals (2 groups of 3 opposite each other, 1 each for the end of each of the 3 windings). There are (in those motors that can do this) 3 small links. If you see those 3 links in parallel across the terminals then the motor is most likely wired in delta configuration. It you see the 3 links being used to connect the 3 terminals on one side together that its wired in STAR.
*Look on the inside of the terminal cover or in the manual for the motor to check/confirm how you can wire the motor and what voltages the configurations are for.*
*3rd* what many engineers and others mistake is that the motor will deliver the same torque over the entire speed range. In the case of a mill or lathe they are forgetting that with the gear box also changes the torque that is delivered. If you just replace a pully or gear box system with a VSD & Motor its also very easy to lose all of the torque variability. This is why many of the small mills and lathes with VSDs still have a high-low or 3-speed gear box.
My current projects apart from a part built Jessie in 7 1/4 inch gauge are a Super 7 and a Raglan 5. Both super groups from the 50s he jokes. 30 years in a workshop with a leaking roof of course. Dragged the second past a rapidly filling skip now arrived. Both free, grabbed a small flypress, filing machine and a power hacksaw as I left on our 4th visit. 11 miles away YOU JAMMY SOD!!! Lovely Work Scott. David and Lily Scott Reading England.
You Aussie's are so resourceful. Amazing job! Thanks for sharing with us.
Huge thanks Bill!
You have a level of patience I will never have, awesome work
Thanks Max! Trust me, I needed it on this project.
Scott Turner Max Brouggy I don't know about you, Scott, but in my experience, poverty teaches patience. Great job bringing her back to life.
Stunning restoration mate, pretty sure I would have sworn my head off as soon as I had to remove a bearing. You really did that machine justice.
Thank you! There was the odd cuss in the shed.
Great work...Love seeing old machines being cleaned up and put back to work.
Thank you. Yes I do too.
To give you an update I stripped the mill down to bolts and nuts cleaned everything up and used industrial grey oil base enamel paint. I bought new bearings. I'm ready to put the mill back together... To clean the old paint off I used a wire brush on my disk grinder. It took the paint off to bear metal. I wanted to send the mill table off to have it milled down .010 to .015 thousand but decided to live with the beat-up surface. I have watched your video several times as I didn't lay the parts out like you did I just piled them in boxes and whatnot so your video has come in very handy. Best wishes from Mike E USA.
Hi Mike. I agree with the table, just take off any high spots with a file or such. Not that critical on these machines and you will save a few dollars. I'm glad the video has helped. All the best!
As always a excellent job you did restoring the mill. I always keep the old bearing race and make a slot in it with a thin cut off wheel and use this to press the new bearing in. The slot makes it easier to remove afterwards. Greetings from Belgium
Good idea. Thanks Tom!!
Trust you didn’t have any left over parts (that’s a good thing). You did a fantastic job. All my respect.
Only a milk crate worth ;) Thank you John!
Amazing! I learned so much about my Enco milling machine watching you restore this one. Thank you!
It was great to see someone that actually knows how to pack (lube) a tapered roller bearing. I couldn't even begin to count how many videos I've watched where someone is upgrading a mini lathe spindle with tapered roller bearings and all they do is wipe a little grease on the outside of the bearing and install it. Great job on the rebuild. Like you I would have jumped at the offer of a free mill project like that.
I guarantee you this dude is a motorcycle mechanic. That's what I do for a living and I see a lot of similar habits.
I just finished restoring the same mill. You are going love that thing. I use it mainly for wood and aluminium projects. I’m looking forward to seeing what you can do with so I know.
Thank you! Yes, I'm really enjoying having it.
You had me rolling when you said "big beautiful thing". LOL
I love the look as hes waxing his shaft 🤣🤣🤣
Magnificent re-build Scott! I'm certain that machine will outlast anything being manufactured now! Bravo!!!
Thank you! Should out last me to the next overhaul.
A testament to your skill and determination. Had one myself and managed to build two steam loco's with it!!
Thank you Neil! Two steam locos! Respect! I'd like to make a small motor one day.
@@ScottTurnerformeindustrious
Scott,
Also, in 2004, a group of us built the worlds largest gas turbine engined aircraft, a 25ft wingspan B-52 with eight engines!! Used my RF-25 to build all of the undercarriage, including brakes and ABS systems!! There are pictures of it crashing at the British Nationals in August 2004!! A sad day.
I can see some T-Shirts coming soon. Forme Industrious “It’s a beautiful filthy thing” 😆
Great idea!
Or filthy animal...
Why would someone give you a thumbs down, great job
Oh well! Many thanks!!
This is an excellent example of the wheel. Both the person whom gave it to you, and you. Well done.
Many thanks!
Wow, quite a transformation! I don't know how you remember where everything goes. Nice job, thanks for sharing.
Thanks Rob!
How many "FANTASTICO" I would like to say you Scott! After this project I 'm sure you are the best maker, worker (I don't know) that I like to watch.
Beautiful, a masterpiece of mechanics, patience and skill ... The best!
How the real situation of fire in Australia Scott? Now in Europe we are talking about the China Virus only.n :-( By the way one, I hope one day to meet you... Ciao Scott sempre il numero uno! (every time number one!!!!)
Very kind Michele, thank you! I think there are some fires still causing problems. Summer has a long way to go but the large scale fires have burnt out I believe. Yes another worry is the virus. All the best and one day we can catch up. thank you!
Man this brings back some memories! I know how much work that was and yours was in worse condition than mine, so great job. Don't make the mistake I did and ever sell that thing! They're such great workhorses. By the way, when I had the same mill I made a little something I think you might have more use for now than I do. I can send it to you if you want?
Thanks Phil! I referred to your video quite a few times, just so you know why there has been a spike in views on that video ;) It's a keeper. I need to fix the backlash in the lead screws I think (0.25mm and 0.5mm). Looking into a DRO which would help with that backlash. If you like, send me an Email and many thanks; sturner2022@gmail.com
Scott Turner oh cool. If you DRO it id be keen to see it. Picked up a RDM-350 version of these. Just starting to tool up and learn machining.
What a monumental undertaking. Your patience and courage are to be commended. Well done.
Many thanks!
Looks brand new. Great video!
Thank you Rick!!
Loved it, made full eye contact with you when you said "you big beautiful thing.." gonna have to have a shower now :) Great work mate, looks awesome
Ha!
That was well done, I have the original Long Chang version, needs the same treatment ( don't think it will ever happen on the long list of "Round Tuits") couple of observations I would not have use 3 in one, that stuff drys up like shellac, ( never use on your sewing machines) plus that old chisel happens to be one the best Stanley made from the seventies, the stuff they make now is rubbish
Never knew that about the three in one. Easy enough to remedy. The chisel was put to bed unharmed, maybe a little shaken... Thanks!
Nicely done. Great to have subscribers who offer to give away machines they don't use. Guys like you can give them a second life
Wow! There was a lot more to that than I ever imagined. Thanks for sharing!
Thanks Paul! Yes it had a few bits and pieces.
Brilliant Mate, the Australian way, if you aint got the proper tool, make another one do the job, love it. Cheers from Brissie.
:) Yes where there is a will there is a way. Cheers!
Take a drink every time you hear “filthy” - if your liver can take it, that is. 😝
I know! I deleted 90% already before the final edit.
I’m a retired Fitter & Turner and have one of these machines. It’s very obvious you know what your talking about and doing. Thank you, John.
Now I understand why some of the cruddy old pigs that went for almost nothing at auction brought so little. You've made something really valuable here!
Let me guess, the guy in SA thought about and he wants it back😂 . Epic rebuild Scott 👍
Ha! If he can carry it out of the shed one handed (greased), hoping, naked and backwards, he can have it.
@@ScottTurnerformeindustrious that'd be a sight, as always great work.
Greasing a bearing is kind of hilarious, because it's exceptionally simple but still quite strange. "Yeah, we're just gonna grab a handful of thick lube and jam it into a bearing until it's literally overflowing. Then add a bit more." lol
Yep, that's how it's done. Slam that grease in there, and try not to get it in your hair etc.
These are the machines that grow on you! you know all the intimate details inside and out, I have several like this and I smile every time I use them. Great job on the rebuild. Hi from Idaho USA
I think you are right Jerry. Many thanks and all the best!
You can’t believe how happy I am with this video. I have the exact same machine in my garage waiting for the same treatment, but I was afraid to have a go at it. Not afraid anymore now !!
That's great to hear! It's not that hard, just dirty and heavy. All the best with it.
14:55 - 15:05 You should be an actor, Scott :D
I'm working on it. Might take me a while :)
friday 13:00 ,Madrid,Spain feeling a hard week of welding on my eyes...suddenly I felt a disturbance in the force...a guy in Australia adjusting a keyway with the lathe and a chisel . WTF!! broaching machines manufacturers desperately selling stocks XD
Ha! Yes, but it worked great :) More dodgy stuff to follow ;)
Just had one give to me that I want to restore, your video will be an awesome help in the restoration of my RF-30. Thank you.
This 30 minutes has flown by and I've not noticed my bloody gout. Reminded me of the Diemaster I used to drive and the Timken bearing package, my old town Northampton UK.
Thanks for sharing this beautiful rebuild!
Cool! I'm amazed my Mill Therapy works on gout, well I'm glad at least the video took you mind off it. Thanks and. All the best!
How in the heck did you keep track of all those parts 🤷♂️
Oh, well....I have a box of parts left over ;)
"You big beautiful filthy thing you!"
If I got a nickel for every time I heard that said to me,,
I'd be at least 5 cents richer

Nice gift, wonderful job of getting it back to shape
Good show
That's funny! Well you'd have more than me! Cheers!
It's so rewarding to see what a little bit of love can do...
True! Thank you!
I'm envious!! Of the gift, the end result, AND all the horrible fun you must have had in giving some long overdue TLC to a nice piece of (Free!) kit!!
should re-title this video to "Beautiful Filthy Thing"
Done!
Really nice restoration. It gave me inspiration for restoring the old early industrial wood mortiser that my father gave me last year
Thanks Alex. Love the old machines. They are solid and for the most part repairable. All the best.
I have the same or close to a drill mill like yours, it's every bit as bad as yours. My half-nuts are not good, so I might have to replace them. One thing I'm going to do is send the table out, have 10 thousands removed maybe up to 15, and clean the table up a bit. I'm sure my drill mill was owned by a blacksmith cause everywhere there is a flat surface they must have used a hammer and pounded on it. I paid 140.00 for the mill and lots of parts including a pully and shaft were missing I just started cleaning my mill up yesterday and today watching you rebuild yours has been a real help for me. Thanks, Mike E. The Bench Jeweler.
I'm glad the video helps with your project. Yes the half nuts will be worn on the older machines. I've adjusted mine but they are still sloppy. All the best with the rebuild!
Nice restoration! That beast of a machine will give you many years of great service! I always enjoy your videos!
It’s nice to see you working in the shop... when I work in my shop right now I can see my breath!
Ha! Well it's been Hot and humid in my shed. Very sticky. I guess the cold is not a lot of fun. I guess that's a good time to fire up the forge.
Brilliant and thoroughly enjoyable to watch the transformation of the mill
Thankyou Ian!
You made that restoration look easy. Well done!!!!
I know first hand how much work goes into restoring old machines. Truly fine job Scott!
After it's all done, it feels worth the effort. Many thanks!
Oh my brother down under.... now you are hooked! You are going to LOVE having that machine! Congrats! I use my mill all the time.
I'm loving it! Huge thanks!
That is an amazing transformation beautiful work as usual .
Thank you Pablo!
Brilliant job mate. Well done.
Thanks Branden!
Scott, you really showed your stuff on this one. Amazing, great job.
Thanks Lee, really appreciated.
The chisel to enlarge thec keyway is genius, tucked that into a corner of my brain for future use.
Thanks Mario!
Respect!!!! Beautiful restoration Scott!!! Congrats my friend!!!🛠
Thanks Igor. I've been using the machine everyday since, cheers!
The reason I watched your video because I own an older jet 16 inch drill mill, I want to remove the backlash from the table feeds. With the help of your video I now have the courage to start the repair work on my machine, thank you and by the way your rebuilt machine is awesome.
many thanks! I hope your restoration goes well.
@@ScottTurnerformeindustrious I stated the repairs and started ordering parts. One thing I learned order generic parts from other vendors, the Jet replacement parts are overpriced.
Wow! Easy as pie when you use the right tool for the job. Thumbs up great looking finished
Excellent as always. Thanks!
Great job bringing to its former glory, looking forward to your videos putting in action….. 😎👍🏻
I have an RF-30 of the same year that is like new, this made want to tear it apart...powerful vid! Really enjoyed it.
Thank you Jim! If it is like new maybe a basic clean up and re-lube around the moving parts would be all that it needs. Mine had a lot of use and lots of grime.
Finally got a chance to watch the whole thing. Awesome effort. Superb job.
Really appreciated. Thanks for taking the time to watch!
Excelente trabajo!! Da gusto ver estos videos!! Gracias 👏🏻👏🏻
Thanks Harry!
THANK YOU...for sharing. Watched and very much enjoyed. Very nice job.
Glad you like it, thank you for your feedback!
Beautiful job. Thanks for sharing.
Thank you George!
This is a really great reminder that you don't have to buy the newest/greatest/whatever tool. Oftentimes with a bit of effort, you can get a really good older tool that can be made terrific with a bit of TLC. I'm in the midst of restoring a ShopSmith from 1956. It's taking me a long time, but for the cost of a few bearings, spare parts, and paint, I should have a perfectly serviceable tool at the end. Unfortunately, I doubt it will look as nice as Scott's work! ;-)
Very true John. I'm always on the look out for old machines and tools that can do with a bit of TLC. Thanks and all the best!
That was an epic restoration job, find it really interesting how you got it working again. 👍
Thanks Kevin. Much appreciated!
An amazing afternoons work! Lol, it looks awesome, thanks for sharing
I wish just and Arvo! Thanks Alex!
Good job on the resto. When you get tired of cranking the elevation handle, (if you haven't already), an old ½" plumber/electrician's drill, (IE: Milwaukie Hole Shooter, for reference), makes a capable & easy motorization of the elevation.
These type of HD drills used by plumbers came w/ a reversing switch, making it a good choice. Without a reversing switch, you have to crack them open & get wires into the fields.
I had 2, one reversing. Trying to get the chuck off the 50 yr old drill has kept me from re-wiring the non-reversing. After pounding & impacting 'til my arms ached, I'm now trying the penetrating oil & get back to it in 6 months technique.
Cheers George for the tip. So far I'm okay with how it is, but you never know what might be done in the future.
Fantastic strip and rebuild instruction. I have a Warco Major which is the same, and I need to take it apart to get it down into my cellar. All questions answered, it will be a doddle now. Many thanks Andy. UK based.
Thanks Andy! They are simple machines really, just heavy. All the best for your refurb.
@@ScottTurnerformeindustrious By the way, where did you get your chuck and collet set from? thanks Andy

Absolutely great job as always, it was like a movie that I didn't want to end. WAW 👍👍👍👍
Wonderful comment. Thank you Mustafa!
Thanks for a really good restoration video! Just bought me one one these and had to take it apart for transport. Your video helped A LOT!! I must have watched it 10 times before going to pick the mill up :)
I'm glad the video helped, that's what it's all about. Happy milling.
Great Job Scott As Always!
Thanks Michael!
Just found this channel . That was no mean feat. Everything is heavy and trying to maintain the potential precision and resetting gibs etc is a mammoth task. Well done. Ive just boughtthe same thing but under the axminster zx30m guise. Just need to build a bench and get it up there now 👍😎
Très joli travail bravo belle restauration à bientôt salut Jeannot 😉🛠
Merci Jeannot!
Well done!!! I've got an old Park planer that I need to get 'round to restoring that in similar shape. Thanks for the motivation!
My pleasure and thanks for your comment!
Fantastic. Really enjoyed it. It’s inspired me to take my mill down further and clean it out better!
Thanks Mike! If it has had many years of service I guess it cannot hurt. These machines are relatively easy to work on.
Scott Turner I’m mulling the idea of a DRO. Go on.....do one....inspire me hahahahaha
To be fair, I normally don't care for video's that are this detail intensive, BUT found this one to be very interesting. I have the same mill and believe there is a restoration in the near future. Thank you very much...
Glad to be of help. All the best for the restoration.
