Quill movement counterweight vv spring for SL in vertical mode: A pulley is not silly in the least as far as I am concerned. As my SL is static being attached to the back of the Myford S7 I will take a cord up & round a pulley and then down behind the S7 with a bag filled with redundant items as weights.? Leslie

Re: Which motor is better?

 

I ask because I am going to let one go, the 7750 seems to run more quietly. The U90 seems to spin at higher rpm??


Re: Threading Attachment?

 

I have one made for the job. It uses simple gearing to get metric pitches down to 0.5 mm. It would need substantial modification to get finer pitches or inch threading in tpi. It works using a crank handle on the spindle, rather than being motor driven.

The gears for the Basic lathe use 17 tooth gears to get close enough to inch pitches, but not many of them. If you have definite pitch requirements check that you can get them with whatever gearing you choose. There are clever ways to get inch pitches on metric lead screws and vice versa, and more obscure things like Mod and DP pitches, without using large gears like 127 tooth.

The U3 uses 1 Mod gears which are easy enough to get. The Basic uses 0.75 Mod, which are quite difficult to find.

Re: Download files in one go

Re: Which motor is better?

Re: Which motor is better?

 

Carl, being in the US, 120v is not an issue.? I was more thinking that if I found a Unimat(or other small tool) with a higher voltage motor, I could then easily run it.??


Re: Which motor is better?

 

It can also step down 220 - 110

Re: Which motor is better?

 

I believe they are about equal.? THe best motor offered was the U-100 which is a continuous duty motor none of this 80% duty cycle stuff.? Not sure but it may be possible to put ball bearings on either one instead of the sintered bronze aka oilite bushings

Re: Threading Attachment?

 

Addition to the last message.? The do it yourself threading attachment file is in the Unimat 3 group file section, listed under Other Files,? as Threading Attachment Made on the Unimat 3. Happy Machining !


Re: Threading Attachment?

 

I have seen plans for making a geared threading setup for the U3 from scratch and also plans for adapting a Sherline threading setup to the Unimat 3.? I just looked at the Unimat 3 files from the Unimat 3 group on groups io and found the Sherline to Unimat 3 conversion.? I have not taken the time yet to seek out the build it yourself threading set.? The only thing I remember about it was you cut your own gears and they were quite large, probably module 1.? Happy machining!


Threading Attachment?

 

Is a geared leadscrew threading attachment available for the Unimat 3. ?I imagine one could be built if it is not redilly available.

I can’t say as I never tried to do that. I’d bet one or more members can definitively answer your question though. There are a lot of images so i suspect the full set would be quite large to download.

Re: New unimat member-circular saw arbor

 

Thanks for that. I didn't know there was a files section. Very useful. Is there a way to download all of the files in one go? So I can read them at my leisure.?


Which motor is better?

 

Guys I was wondering is there much difference between motors? In particular which is best between the common U90 and the later 7750. I have a choice, Both motors are 240v versions.?

Hi

Couldn't you rig up a counter-weight system to lift the head. It would be cheap, easy to make, easy to adjust and sensitive as you want.

I'm still looking for a quill return spring, so would appreciate any offers, but noting US offers carried an absurd import taffif! Thanks, Leslie
