Making A Fly Press For The Workshop | Part Two - The Frame
Вставка
- Опубліковано 20 жов 2023
- G'day everyone,
In this video I will be moving along with the build of my mini workshop fly press. In the previous video ( • Making A Fly Press For... ) I managed to machine the base. All 25kg of it on my relatively small milling machine. If you haven't watched it, I suggest that you do to familiarize yourself with the scope of this project.
In this video I will finish off the frame, which will be made from welded pieces of 75mm solid square bar, roughly 3 inches. This is solid enough for this project. Before it can be welded it will need to be tapped using by massive 40mm square thread tap set, which I made a few months ago. The square thread is better suited as a power transfer screw than a normal 60 degree V thread.
However tapping with such a large tap set is going to be a very difficult and drawn out process.

Part One (ua-cam.com/video/I2OPgacXKtk/v-deo.html)
That sudden break to "I broke the workbench" was pure comedy gold.
The band saw saga continues
How did you not say 'band sawga'
When he mentioned the friend I half expected him to say he told them to pound sand 😂
My jaw dropped
It gets comments and that's how UA-cam's algorithm works.
I reckon at this point he's just never gonna get one
"Grinder and paint make me the welder I aint". Great project.
The milk crate! An Aussie backyard wouldn’t be complete without one.
For just ten cents a day, you can help poor, unfortunate machinists struggling to cut material afford a bandsaw. *In the aaaarms of the angels*
Show neglected puppy in cardboard box.
I love our friend Mr hackie, i don’t know why everyone wants a bandsaw so much. Hope he never gets one! Hacksaw gang for life!
@@jc13781 Something tells me that in an upcoming project, he's going to make a mechanical hacksaw with a throw large enough to clear chips from this size stock, and automatically shut off once the cut is clear. I've been seeing them for over 46 years, so it seems likely that it's a project worth considering.
@@jc13781 on 75mm bar? your crazier than me. 😁
@@RNMSC He could always follow the power hacksaw build schematics that *JSK-koubou* finished last month.
Or as they put it *_"Elegant mechanism for DIY power hacksaw."_*
As far as Japanese machinist UA-camrs go, their videos are very watchable.
Wow, tapping that hole by hand deserves the Ca Lem prize for near-impossible stunt machining! I'd have run screaming from the shop faced with that. Awesome job.
This is a MASSIVE accomplishment for a home workshop project using shop made tools. You should be very proud and anyone should be impressed.
You're easily the hardest working home machinist in the Internet.
(Some manufacturer needs to sponsor our friend a horizontal bandsaw)
Hardest working is I would say Cà Lem. But artisan makes is definitely very innovative, still hard working and great fun to watch!
@@trashes_to_treasures I would agree, but is Cà Lem's workshop at home?
I could've been mistaken, but I always thought his was a commercial workshop.
You are by far the most patient maker I’ve ever seen. If you told me that your mini mill was broken and you needed to hog out 10 kilos of steel with a bastard file, I think I’d believe you.
That was a brilliant cut. "this can only end one w-I broke the work bench".
I watched those videos of making the taps and tap-wrench and found myself thinking you were either an imbecile or a madman. While you may indeed be mad (I am not qualified to answer that) if so, you are one of those mad geniuses of popular fiction, and I doff my tatty cap and bow my head as you pass. Congratulations on the enormity of your triumph.
"I broke the bench" had me lolling for ages. You are a legend.😂
Next time you need to tap massive threads, do a first pass on the lathe to full depth. The. Follow it up with the square thread tap. The 60 degree thread profile will clear out nearly half the profile so the tap cutting forces will be much smaller.
Line boring would also be a good option too. It would be possible to go to full depth and profile without needing any taps. Plus you would have the option of multi start threads.
Another option would be to cut the threads in a bronze sleeve instead of the steel block.
He said that the lathe cannot be geared to cut an 8mm pitch thread.
If that is true, gawd knows how he's going to cut the lead screw ... probably with a hacksaw 😂
@@johncoops6897 One advantage of the square thread is that it can be milled with his helical attachment that made the taps with the exact same setup.
I've seen that done with those long acme taps which are a hybrid of a v thread and acme. Which is done for the reason you listed. I thought about doing that at one point but the length of the tap would have been close to 60cm long (a hybrid v and square tap), that's as long as the mill table and longer tha the lathe can swing. If i made it two taps I might not be able to guarantee that the square profile follows the already cut lead.
@@ElectricGears I was going to make a similar comment.
I didn't expect that tap set to be able to do this job in steel. You proved me wrong, great job! Looking forward to the sequel!
Neither did I to some extent
Finally a bandsaw lol
😮 I take my hat off to you ,if the phrase don't throw in the towel applies to someone, that person is you, amazing.
You might have tried a hard bronze insert for the thread. Besides being easier to tap it also has better friction characteristics when paired with the steel screw. I have had problems with high stress steel on steel threads before.
Yeah the leadscrew I have will get a heat treat to help.any galling or stress issues. If I ever flcut a triple helix the plan is to bore out the top and push in a weld a threaded insert
Its coming a long really nicely, I am well impressed with your taps cutting that screw block....I guess all the hacksawing paid off some making sure you were strong enough to keep going on that one
Looking forward to seeing the next part
Thanks for sharing
Nice build😊
Preheating the parts on top of the forge would be a hustle free option, as well as more even heat distribution.
TIG welding it then with a min. 3.2mm electrode @200amps should be possible. One weld and opposite side, then back on the forge and go on the other part.
Should result in a more stressreliefed final part.
Each episode of this Fly Press series is even more epic & awesome than the previous one.
I've been patiently waiting for the bandsaw build. It's got to be on everyone's wishlist.
Congratulations on breaking the bench - first time I've witnessed such a thing!
For removing high amounts of material with the angle grinder I can highly recomment the 3M cubitron 2 discs. Both the hard rough grind disc and the fiber discs in 36+ grid are working extremely efficient.
Also you did good in preheating the steel before welding. Everything over 30mm thickness should be preheated.
You hopefully did not weld "falling". Downhill welds usually lack strength, as they fail to properly penetrate the base metal.
Also you should definetly clean the slag from the welds after each pass. Each piece of slag can end up as an inclusion, which in the end would be a point of failure. From inclusions, cracks tend to spread out.
Overall this looks like a fine job, considering the tools at your disposal.
Looking forward to see more :)
He clearly showed in the video how he removed the welding slang between each pass. You truly didn't need to lecture him on that 🙄
@@johncoops6897 really, he did? It looked to me like he did way more passes than he showed on video. Welding that many passes can take hours.
Also I didn't mean at all to belittle him. It was meant, as you said, as a lecture. Or rather a lesson. I do it professionally, so I like to educate people who might not do it as often or might not have the knowledge, on how to achieve the best results.
I didn't mean no harm at all.
@@malteser0212 - yeah, it was good general advice. Not that anybody would try to lay a weld over the top of slang.... also keep in mind he used MIG not Stick, so it wasn't something so thick that he needed to chip off. He would have been better to use stick, as it would have taken ages to weld that thing up with hobby grade MIG wire, and also must have cost a bloody fortune 😃
@@johncoops6897 I know he used MIG (actually, I hope he used MAG, though in english speaking countries it doesn't make any difference. MAG just uses part CO2 gas. MIG is, as the name suggests, using only inert gas.)
But even with MIG, that little bit of brown glass like slag should be at least wire brushed away in between each layer.
And well, whether you use hobby grade MIG or stick, these deep welds take long either way.
Why would it "cost a bloody fortune"?
@@malteser0212 - OMG, dude!
1. I used the term "MIG" because that is what he stated in the video.
2. He clearly showed himself using a wire brush to remove the residues. You can confirm this exceptionally easily, simply by watching the video.
3. I personally use >85% Argon, but I have heard that some cheapskates use CO2. In any case, who cares?
4. MIG/MAG welding wire and shielding gas is significantly more expensive than using Arc welding rods for an equal fill. Hence, it "costs a fortune" in comparison to Stick Welding. Hell, it costs me over $500 per year just to rent the empty gas bottles for my MIG. This is called "mathematics", have you tried it?
5. Of course he took ages and many many passes to fill those huge fillets. What point are you trying to make?
However, the main thing I was trying to point out is that he would be more likely to get decent penetration using a Stick Welder on these large fillets and hefty steel chunks.
I have no idea why you are arguing, nor what you are actually arguing about 🙄
On the subject of super high cutting force needed for manually tapping a multi-start thread: Consider taking off the 2nd, 3rd, nth start at the beginning of the tap, and having a reduced profile for the successive helix near the end of the tap. This lets you cut one helix in each pass, and creates an index for you to start the next helix.
Didn't they make taps like that with only a single tooth for the other 'starts' in the late 1800's?
You do excel at doing heavy engineering with light engineering machines.... thankyou for your videos...I lose track of time watching them....I find them relaxing and inspiring at the same time....stay safe
Had to say it - the base to the fly press looks like it's the base for the Millenium Falcon!!!
Leaving a comment and a like not just because I am enjoying it but to help The Algorithm so you can eventually get a bandsaw.
Fair play to you with those taps. They worked much better than I expected!
Outstanding 👏🏼👏🏼 seriously impressive. I pulled a 14 inch MK Morse cold cut chop saw from a scrap pile a while back. Worked just fine but was missing a few things. Most importantly the vise and forcing screw. I decided to make a new one from scratch and im almost done but had a few hiccups as far as design elements. Watching your video's is very inspiring so just wanted to say thanks ✊🏻
You definitely got your workout in cutting the threads. Glad to see you using a bandsaw to cut that much metal. I guarantee that will save your shoulder and elbow in the long run. Be safe, keep making, and stay awesome.
For weeks now I've been waiting for "one more hole to be tapped" :-)
Edit: pretty impressive what you managed to achieve in your small home shop!
1:27 in a move way more controversial than bob Dylan going electric the Artisan finally goes bandsawing!
I think I would have made a 60° thread profile tap thread at the same pitch and remove most of the material first, then run the square profile taps to finish it off.
WOW, nice work and progress. I can't wait to see the finished product. Thanks for posting and take care!
Wow! Here’s to your determination and perseverance!! Well done. You’ll always keep the lessons learned from this endeavor, and will make you an even better machinist. Looking forward to watching your next video.
Even after seeing before making of giant taps and wrench, it still amazes me. It just looks so huge!
Great work, and impressive perseverance . Very nice chunky design, this will be a fine looking addition to your shop, enjoyed.
Congratulations! You can be proud of yourself that you made it this far.
Bloody brilliant!
glad the taps held up for this job.
Big tap wrench is the understatement of the week
Outstanding work, well done!
Interesting project which includes many aspects of metalworking.
Finally! He has used a bandsaw and not pure insanity! Praise the lord!
Looks great, awesome work!
Amazing work!
Excited to see what you do next.
Wooow !!!! el proyecto va delante sigue asi hermano vas bien muuuuy bien esperando la 3 parte con ansias.......👍👍👍
Man, that threaded through hole was Damn impressive to watch.
I've once cutted a m45x1,5 with a die on a homemade spindle and it was absolutely brutal but boy comparing to yours, mines seems like a good evening walk through a park in fall season😂
I was waiting for this video showing that tap in action. Loved this - great job!
Shout out to your mate with the Band Saw bc you would've been there forever trying to cut 3 inch bar stock. 👍👍
Cutting that thread by hand? Madness.
You are so ambitious, amazing work mate.
Coming along great.
I enjoy all your videos. This is a unique project that I want to see in action! Keep up the fine video filming and editing. Narration is top notch as well.
For tapping in future use stuff called CT-90. Thick brown goop that smells like crap but it really cuts down on binding
I am totally impressed by your tenacity in these projects. Possibly slightly disapointed by you borrowing a friends bandsaw, but I think I have said previously, if ever I win the lottery, I will be on to Hafco to deliver one to you.
The project itself is coming along well though, I couldn't imagine what you were going to use the taps for when you made them. When you come to do the square thread for the shaft, I think I'd try cutting a good bit out with an ordinary threading insert first, square threads are supposed to be buggers to cut, which is why we moved to Acme, not that I have ever attempted either of course.
MOST admirable👍
Beautiful work!
This is a monumental moment he finally used a bandsaw
Yet he didn't use one... 🙄
Not mine, I just took it to my friend who has an industrial one and picked up the stock a few days later when he got around to cutting it up
Glad I'm not the only one that just broke and screwed their work bench together, probably around the date this video was uploaded. Did use some titebond 3 so it should be stronger than it was.
Some heavy metal machining going on there! You will have arms like a bodybuilder when this project is done.
Nice job 👍 Enjoying thebuild
You breaking the workbench. Not laughed that much in ages! 😂
A for effort, i wouldn't know were to start keep em comin
Impressive 👏
Looks great
great work !!
Very nice project.
Big chunk of metal time!
Your experience with the big taps has convinced me..... I will be happy to deal with the difficulties of internally threading a sleeve nut which is then welded into a block using a drilled then bored out hole.. Especially since it's WAY too uncommon to need to do anything even close to this size range in an average home machine shop. But kudos to you for doing it this way. And it DID result in a very nicely designed and made extra large tap wrench.
It would havr been a lot less work to just buy a lead screw and nut. 😂
Amazing
Back clearance makes all the difference. Even on professionally made taps, I've had to grind back clearance to even think of tapping harder metals like titanium.
12:15 I made an attempt to create a 5 start 1/2" tap in a piece of delrin and I was still unsuccessful. Multi start threads are very difficult.
You probibly already own a perfect pre-heater - a barbeque. Steel and steak at the same time!
have you ever considered adding a second gear to the mill? like use the same belt and then throw a 2:1 or ever 3:1 just for drilling so you only change the belt out of place and you get a lot more torque
Loving the series, but buy yourself a 9” grinder for the thicker stuff
Gday, you did good to tap that thread, not an easy task but the taps and tap handle held up well, brilliant job mate, cheers
I used to heat up my thicker materials in an old oven I kept for just that reason. I left it in the back yard in a small wood shed until I needed it.
Well done - that's an incredible amount of work.
One option if the tapping hadn't work out, would have been thread milling, similar to how you made the taps initially, except you could have a spinning tool in the chuck, something like a T-slot cutter shape, smaller than your thread ID, and offset in say the Y axis, to take a cut). Then you would have your workpiece on a rotary table set up with the axis vertical, and have your mill Z axis linked to your rotary table axis with a custom geared setup to get your 8mm pitch.
Or alternatively, a live tool set up on the lathe carriage a bit like a toolpost grinder, but with a cutting head. Then, machining with the main lathe spindle switched off, and only turned by hand (spindle crank), and the change gears set up with the coarse 8mm pitch for linked carriage motion. Depth of cut would then be controlled by the carriage fore/aft position.
I'm really looking forward to seeing you crush the rest of this epic build, and then crush some more stuff with the epic press after that. 😁
finally he did it
Very easy with hack saw? You must have a very good hacksaw haha. Love your work mate, I learn a lot from your channel.
So much grindinggg. Cool though. Thats one hell of a tap wrench
You could always bolt on some 5mm thick side gussets to strengthen the frame welds
Looks like a millennium falcon 😊

GIDDIE UP!
With TIG you go back over it with just the torch (no filler rod) and blend your weld to make it look better.
12:15 The fireball tools wise is probably appropriate for the task. The bench would need some steel plates bolted on.
Nice work Artisan Makes. If want to improve the appearance of your fillet welds , purchase a flap disc with rounded edges or curved edges. They leave a polished looking finish.
That is exactly what i was using here
They now make a flap disc with a large radius for fillet welds. Much larger than the one you were using.
nice thing
Nice work! Although I wish you would have used a flux core vice short arc on something so heavy. Non-fusion becomes a big concern with short arc on something that thick.
Good job. Your welds look at least as good as mine. Which is ok. I never wanted to be a welder anyway.
I nether did I :)
Haha, I just realized the base looks like the millennial falcon... epic!
I cannot believe the hacksaw has been retired :) :)
it hasnt :)
Угарнул с верстака)))
The base of your press kinda looks like the Millennium Falcon lol 😂 the star metal wars saga continues.
19:30 Now this extra piece is the main load bearer. The part is really good for stiffness. Add a weld where you can't see it from this view, below the overhanging part , the one with the holes. This will make it really strong when the threaded "head" gets pushed up.
It couldnbe like this, but I didn't do any FEA simulations with the plate added. That was a last minute addition.
The one piece of advice I have is the wire speed of the mig sounded a little slow otherwise a good job plenty of welding practice in this tool. Looking forward to seeing your next video
lmao that cut at 8:12 was fucking gold! still those taps are very impressive
1:22 So you admit your defeat to the bandsaw
My friend offered so it seemed easier.
