Primed by the earlier post of a 3d printed steady rest for a Unimat SL or DB, I was inspired to create my own for my Unimat 3.
|
Hi Peter, nice steady.
Can I ask what material you used. I have mine 3D printed in PLA and I'm waiting for the small bearings to go on the end of the 3 legs before I can use it.
Do the legs wear much?
|
I print in ABS and did this with a solid fill, even then it was less than 30m filament, i havent tested it yet, but my thoughts are that the legs can easily be reprinted for a matter of a few pennies worth of filament, so why worry about wear, the ABS should be pretty good for that anyway. testing will be later today. worst case wear wise i could create a leg with a hole at the end and turn up some brass inserts to pop into the ends.

Hi guys,?
It looks like the business. I would have thought that sacrifical legs approach would be the best option.?
Great work.?

Thanks for the reply. I used 20% fill and 1.2 wall section, feels quite rigid. The arms are printed on a 3D Resin printer, I am do the body in that later. The bearings (the brass looking parts) are 4mm ID, 9mm OD x 4mm wide, these are still in the post. I also done have the small screws yet. I suppose it all depends on what you use them for. Mine will probably be to hold 6mm + bars the centre drill the ends.

What is the cost of having a steady rest commercially printed for either an original Unimat or a Unimat 3, or who is selling printed ones and for what price?? I want to compare printed ones to buying original on?Ebay.? ?I am also thinking that I can sell an original one on Ebay if I no?longer need it, but maybe a printed one has little resale value? There is no need to tell us that you have this great printer and CAD system, you can design and print your own, for almost no money.??

You may be able to buy a unimat SL fixed steady on Ebay usa, but I haven't seen on for sale in Europe for the last 6 months.
I can tell you that the cost for 3D printing form Shapeways, a 3D printing company. would not be cheap I am guessing more than $100.
When I've proven my steady I'm going to post them here for all to use.

Hi Les,?
I am liking that, I drive an SL.?
I don't have access to a 3D printer at the moment. Most of the ones I know of are printing mask bits.?
I would be interested in the necessary files for that for later, is there going to be a later??

Hi Peter?
Would you mind putting the modeling files in our files section or somewhere like Thingeverse.
Also what Modeling software are you using I'm still struggling with Fusion 360.
There are easier ones but Fusion looks the best.
With Covid19 restrictions making me stay at home I have the time to learn a new skill.
Thanks in advance Mike

I will have a go at putting the files up, I am already on MK2, with the nuts inset into the body. As an ex drawing office manager, I just do my modelling in a full cad package, generally autocad. But I can do it in others too.

ok, files are uploaded, i have put the mk1 and mk2 stl's and the mk2 CAD files in autocad and bentley microstation.

Thanks Peter Fusion 360 is an Autodesk product it is free to the non commercial and student user. I was a Senior Civil Engineering Draftsman before computers were common place on everybodies desk. My drawing technology was Rotring ink pens on Tracing paper or film and expensive scale rulers. I seem to recognise your name did you produce drawings for the U3/4 Threading Attachment. Because I just 3d printed the gears for it

You folks never cease to amaze me with the crafty solutions you come up with for things the factory could have done or done better. I recall there was a machine shop in the UK which made a compound feed unit that mounted on the carriage for the Unimat SL/DB. Any one recall who that might have been. Alternatively has anyone come up with one on their own?

Yes I bought the commercial one then did the drawings from those, as even those commercial ones are very hard to find, I am a draughtsman by trade do the drawing was easy.

Well I have to say thankyou for both of your digital gifts.
Something off topic Back in the 70's in Australia we were called draughtsman then they changed it to draftsman.?
Looks like we took the US English version.

I'll raise a foamy draught to that.

I would say that here in the UK either is in use, but when preparing a document we refer to the first draft, not draught. In my 1975 dictionary both are listed equally. I think draught for documents and drawings is on the way out. For drinks, I'm not so sure.

I know the one you mean, but I have not seen on eBay for a year or two.

Hi Peter
I was looking at this website and saw a 3/4 fixed steady.
Only a few things for the SL.
|
Interesting, when I searched on the internet I only found one, and that was from Germany at about 5 times that price. For unimat parts that a pretty decent price.
