Re: U90 motor suppression capacitor

 

Some eBay items are only available via a specific country. If you need Unimat items for example, it's worth trying eBay Germany and asking the seller if they'll ship. However these caps are very generic so I'd also try AliExpress and even local electrical wholesale places.

Many thanks all, I was speaking with a guy yesterday he said have a look in an old electric pistol drill you might find one there, but if not have a look on e-bay and he directed me to the same German site so I ordered one from there.

So will let you all know how it goes when I get it.

Many thanks? Phill?

Loosen off the head stock and the tail stock clamp a bar in each chuck then lock the head and tail stock take out the bar and try a cut.

Re: U90 motor suppression capacitor

 

Just looked again and found Ebay item?223653993396. That's the sort of thing I used before. The listing is from Germany, but the type may get you to a local supplier.
Re: U90 motor suppression capacitor

 

when I looked a few years ago I couldn't find a modern version that would fit inside the motor. I had to fit one outside, and made a cover for it. The only small ones I can see now are rated at 100 V DC or less, so not useable on mains power even in the USA. I can't see another three lead version for mains use, even though I got one within the last ten years. It is the type of safety critical component that gets ever tougher specifications as time passes.
Re: U90 motor suppression capacitor

 

It's not critical. The motor will run okay without it but you'll mess up radio reception around you. Just get one that fits with the right number of wires and the right voltage ratings.?

Re: Unimat SL1000 adjustments.

 

As Scott says, the head stock likely needs adjustment.
How are you aligning the head and tail stocks? You can't rely on just
the locating pin. That is only approximate.

Hello friends!

? ? Just curious if there is a way to adjust the tail stock so it
drills straight thru a brass rod. It appears to be drilling on a slight
slant. Any direction on this would be appreciated. Thanks!! Richy

Can anyone tell me which?motor suppression capacitor I need for my Unimat SL please?, It has started blowing the mains switch fuse and I find I need to replace the?capacitor?but on the one in the motor I cannot read the size or name.

Thanks Phill

Thanks Keith, that¡¯s really useful information and opens up some distinct possibilities. A Googling I shall go!

Ideally I'd like to be able to cut imperial threads as well but (as I understand it) this would require a 127 tooth wheel, which at MOD 1 couldn't possibly fit on a plate between the headstock and lead screw shafts.
Somewhere I have a set of change wheels for inch threads on the Basic (also a 1 mm pitch lead screw) and clever things are done using 17 tooth wheels. It gets very close to the correct pitch - last time I calculated it the error was something like 0.1 mm over the length of the lathe. Unfortunately the gears are 0.75 Mod, which is not common, so sorting out further pitches is a problem. I can't find the charts at the moment. On another lathe I saw lots of pitches using a 19 tooth wheel, but that was for making metric pitches with a ?" pitch lead screw.

A quick example: with a 1 mm pitch screw (25.4 tpi) using a drive of 17:18 gives a pitch of 23.988888 tpi - near enough for 24 tpi, certainly for a short length of engagement. Playing with the numbers should yield other inch pitches. Allowing for a compound gear somewhere in the drive should make many more pitches available. The game is to find lots of pitches that only require a limited number of wheels.

Hi SMJ


I use the Unimat 3? as a? 3d? jig holder? and my jig is in a 3D solid format using? my 3D program , but it should b great to also? have the whole? thing in the? 3D !!

I have a 3D cad/Cam? program PIC 3.3 based on the ACIS? core? (using the *.SAT extension )? that do not support step , do you have the possibilities to export the? fantastic U3 files in that format , (using SAT version 7 works )

It should be? great? to use the native solid model instead of the stl? version that I can import (see attached files )

Is that something that You can help? me? with ?

Best Regards Lars Herrnsdorf
