Wecome! This channel is about precision machining parts by and for (and to the extent of) my Unimat SL1000 lathe.
I have and will be fabricating parts the Unimat manufacturer skipped like a compound rest and external drive as well as steady rest and other unimat tools. This channel was established to help other people that own a Unimat SL 100 or DB 200, or any other small lathe.
Hope you enjoy this

Batch machining... help?
Переглядів 1,4 тис.6 місяців тому
Hi guys. I would highly appreciate your comments. the goal is to machine a batch of 4*0.2mm tubes 5-10pcs to the same length (-/ 0.05mm). Batches can vary in length, but within batch they have to be identical. I thought of hand sanding them post processing just to true them up. Any thoughts? Thanks!!!
Machining a pressure nozzle - most oddball Unimat setting ever!
Переглядів 7377 місяців тому
Filmed exactly a year ago - this is the most oddball setup I had to use on the unimat SL1000 lathe to machine a high pressure nozzle for a machinist. He turned a cone for me (for blacksmithing) in return. All in all - we were both very happy. If you enjoy blacksmithing, machining and machine fabrication - please consider subscribing.

Thank you so much for this video. I just started using my Unimat DB 200 as a mill. What do you use for parallels? All the mill parallels available are way too big for the small vise on the Unimat.
@@Kijiji-ny7qh My pleasure. Glad you found it useful! Parallels - I use two high speed steel blanks 6mm*2mm ground stock. These are ground to size and very parallel ... Yes, regular parallels are too big for the unimat tiny vice :)
@@Smallathe Thanks! Subscribed.
@Kijiji-ny7qh my pleasure again. Glad to help a fellow minilathe owner and maker :)
The controller shown in this video has a programable brake setting, you can turn it of, or adjust in 5 steps. I will add some links to other UA-cam videos about this vey useful motor, that gives a lot of torque and speed range, and is avail able in 500 wat (1/3rd horsepower) or 750 wat (1 horsepower). There is a German YT contributor that has a circuit to replace the lever with a potentiometer, looks very good but I have not tried it yet. I don't appear to be able to add more than 1 comment so I have had to append these to the original comment. _________________________ The German contributions, Many thanks to those guys. ua-cam.com/video/qao7Rex1lZU/v-deo.html German forum for motor mods forum.zerspanungsbude.net/viewtopic.php?f=13&t=55190 German forum for updating mini lathe forum.zerspanungsbude.net/viewtopic.php?f=9&t=603&hilit=edm300 precede both these addresses with the usual http etc These are mot spam but genuine forum sites YT won't allow me put in my comment.

Hmmm. I use an industrial sewing machine and some of these brushless motors have zero torque. There are some new versions now that make substantially more power for punching through leather etc.
@@GTIFabric good point, but lathes rely on speed more than torque. Especially on small lathes - yes, torque would be nice for heavy cutting but the lathe m6 leadscrew would shear off... So I opt for higher speed and 0.1-0.05mm depth of cut.
Can you post the STLs on Printable please?

Did you tap the ends?
@@DavidPlass yes. The aluminium os tapped m6 to secure the resin casting and m8 to screw into the drill press.
Very cool. 👍
Thanks mate :)
Great video as always. Hey I was wondering if maybe you could do a steam engine build or a build for one of the tiny engines that come in the unimat manuals? Like a little series step by step for all the unimat owners out there. Love the content and would like to see more of the unimat. I was starting the river queen steam and thought it would very helpful to see it done as there are only one video of such a build on the unimat.Just a thought.
Lovely idea! I've been thinking on it. It's going to take a while - I have previous projects to do... :)
Good idea, I havent bought an opinel knife for some years, because i dont think the locking mechanism is legal in UK in any public place. I use a TSPROF system to sharpen kitchen knives, pen knives, tailors shears and scissors,, etc. and found it to be very accurate over some years of ownership. Its expensive to buy though can sharpen virtually any edge type (convex, concave, flat, razors, etc). Thought worth mentioning. The largest version is the most versatile.
Thanks. I never bought one and my friend thought it would be a cool project to make one ourselves. The blade is from a large circular saw.

Well done!!!!
Thanks. Glad you like it :)

Super! How does it work if you position the rotary wheel directly concentrically on the axis of rotation? Is it then not possible to regulate finely enough? Did you check here: ua-cam.com/video/qao7Rex1lZU/v-deo.htmlsi=SFODKuFiVdUz-K3O ? I ask myself: Is there really no non-contacting rotary, cylindrical hall effekt sensor with the same eletrical values as the original linear hall effect sensor 49E?
@@marcoam2610 hi. Well, very good question. I found no problems running it concentrically. You do need to slow down speed before you stop the motor or it stops instantly with a sharp impact. Other than thus it's not a problem
@@Smallathe The controller shown in this video has a programable brake setting, you can turn it of, or adjust in 5 steps.
Thank you
Czy na Unimat 3 też tak można regulować?
English please?
@@Smallathe Is this also possible with Unimat 3?
@@TadeuszTarka-so2dt I think so. It needs to be adapted to the machine specific design. Try! :)
Might it be a good idea to have the cutting tools at right-angles to the way you are showing for shallow tapers?
@@jozefbubez6116 Absolutely. I did plan on modifying it for a 90deg cut, but for now, tested on aluminium and brass, it's working quite nicely. I did think on 3D printing a model. It should work for light cuts... What do you think?
@@Smallathe Hi and many thanks for coming back! As to 3-D printing, at age 74, I know next to nothing although one of our grandsons has made a toy bear or something of a like kind and it took seven hours. Would I not be right in saying that 3-D printing is for plastics only so depending on the exact material would be good for very light use, only? Personally, I prefer to stay with "old school" tech and if it can be done using a drilling machine and file only, so much the better! My interest in the compound slide is for a lathe I started building back in 1978 roughly following a book by Tubal Cain, I think it was, where he states what can be done using 'careful draw-filing'. The result was a 1/ 1/2" centre height, 6" between the centres using mild steel flats and a 1/2" diameter shaft out of what we in l'il olde England call 'silver-steel' which is a half-hard precision ground steel, the shaft running in plain fine-grain cast-iron bearings and bored through to take 8mm collets salvaged from the remains of a watch-maker's lathe which had only hand-held tools. Over the years, I have turned out quite a few projects on this 'mini' lathe but been confined to parallel turning only hence the ability to do taper would increase my possibilities. This may be of interest but I don't know whether there is any way of up-loading photos onto UA-cam? Cheers! Jozef
@@jozefbubez6116 hi Jozef, I too am for metal and machinning but 3d printouts do expand horizons for small lathes - check my post on 3d printed spacers. I have posted exact measurements - so I hope this will be usable for you too. Keep me posted... You can send me images by email via my candy making website www.spicecandies.com or by mail to saar@spicecandies.com.
Unusual and simple way to produce a compound rest.
@@jozefbubez6116 Glad you liked it. Thank you sir :)
Nice looking unit, have you got any more info on it. Are you going to run GRBL on it, or is that bridge yet in the future? Cheers!
Thanks Mate! :) I'm just getting into it - found some boards on aliexpress (for 3 or 5 axis machines) that can run on Mach3. I need more help on this (I'm brand new to CNC world and suck at electronics - i.e. much to learn :)
Very interesting and educational… 👍👍
Glad you liked it! Much appreciated!
excellent
Thanks mate :)
You never showed it on the lathe?

Riser for head and tailstock?
@@kitmaira Spot on mate!!!
mike, is it a 3d printed riser blocks on the lathe headstock and tailstock? I eventually managed to buy a unimat headstock one for my sl100 used (no 3d printer owned).
@@petercallaghan4718 Right!!! Let me know if you need a riser for the tailstock. I don't think Emco made these...
@@Smallathe Thanks that would be great. Can you let me know the cost please? I'm in the UK.
@@petercallaghan4718 Well... assuming the tailstock is uniform and would fit - I can ship it via regular postal services and it should be arrive within 2-3 weeks. The shipping cost would be around 10USD.
What metal is the base made of?
@@ValMartinIreland It's plywood with a sheet of stainless steel on top. About 1/16" or 1.5mm thick.
Love the content great stuff ole buddy.
@@P.Trim69 Awesome to hear it. Thanks :)
Super nice ole friend
@@P.Trim69 Thank you sir! :)
Good luck
Does your locking screw on end stick out past tube's. If does what about making tubes stick out farther so u can machine them all in one pass on Mill laying on there side. Maybe idk. Throwing it at the wall 🧱. See what sticks
I'd bet you could rewire them servo's to take modern end if needed use a CNC program like the proxxons use. If u wanted probably wouldn't cost to much. Idk just throwing stuff at the wall see if it sticks lol
Keep throwing - not bad ideas at all! Thank you! I'll probably keep these (if they work) and alternatively 220v servo's are not that bad. p.s. These are stepper motors. Not servos, from what I see in the manufacturer's website.
I'm check up at this local pawn shop he has some old DOS computers like Tandy,or old stuff that works out of date computer wise. Probably cheap to. See what I can dig up.
Many thanks mate. Much appreciated. I've been told XYZ axis controller (board, matching a modern computer) is affordable - along with MACH3 for hobbyists which is free. I'm working on it :)
They make maximat but that's good or Lil blue.
Absolutely lovely blue :) Found the supplier for the collet and they sell an adapter for ER16... :)
I spent a few weeks trying to get an old CNC controller up and running for a large router, where the manufacturer had gone out of business a decade ago. It used proprietary software and firmware all the way down, and the control box hadn't been made for 20 years. I spoke with the manufacturer of the microcontroller and they wanted $2000 for a license for their new software which MIGHT work with the old box, if I had a Windows XP computer in working order. Eventually I had an epiphany, and threw the whole microcontroller assembly away, and replaced it with a $5 Arduino Nano. An afternoon of testing connections and making up a little perf board circuit, and this $15,000 machine was running on free open source everything. The friend I fixed it for, quit his job and is making guitars full time with that machine now. This would be my recommendation, if you're willing to try keeping the CNC aspect. You're right to run away from getting the original controllers working, DOS, etc. That way lies madness, and I think I'd start thinking about a manual conversion too. But rebuilding your own controller for pocket change is SHOCKINGLY easy these days thanks to these open source communities. Arduino, GRBL, and Universal Gcode Sender have saved my butt half a dozen times. Open source options are free, well trodden, and will probably continue working for decades, and even if they're abandoned, it'll just be because someone made something better that's easy to switch to.
What horsepower is it? I can make you a really good deal on a Allen Bradley drive 😊
Thanks mate! Much appreciated. Currently, after discussing it with a friend who is an actual engineer - we will try to run it using a new electric board and a Mach3 software.
