no great hassle to change out, you just need the 24V motor and a power supply, i added a speed controller too, then its just mount the motor (i mounted mine further away which gives me more room

Hi All I have a unimat SL that works fine but is just a bit too small. I was thinking about the Unimat PC but the motors are under-powered. Is it a big job to change the motor for a 24v DC, has

Watched the TV show Grimm on NBC for several years and just rewatched Season 1, episode 1 on Netflix. ?Note that the clockmaker has a green Unimat on his workbench in the background.

My experience with the main longitudinal leadscrew is, A) it is very mild steel, easily bent, B) being a tiny bit out of true does not affect operation, and C) I have successfully hand straightened,

It'll cost me $56 for shipping of the $25 part

To pin down the bend, you need to turn it and dial indicate. You can only tell so much with a visual inspection and a flat plate or straightedge. And even when you find the exact bend, you may not be

Per Lathe City specs: Lead screw M8-1.0 left hand. ( http://lathecity.com/Learning%20Center%20LatheCity/What%20is%20an%20UNIMAT%20lathe.pdf ) But it might be easier and cheaper to just buy a new lead

THat is indeed the slitting saw/table saw arbor.? Match the bore of your blades to your arbor.? If you need to make an arbor patterned after the one pictured adjusting to fit gear cutters , slitting

I like to cut to nuts in half. Two section go under the threaded rod and a third goes on top where you are applying pressure. This will stop you from deforming the threads.?Jeff

Why fool around with this when you can buy a new lead screw from Tom's Tool Store for $25? Keep the old damaged one as a spare. Regarding straightening, the most accurate way that I have found is to

Hi: To straighten a shaft, roll it on a flat surface. You will know if it bumps. Then if you have an arbor press, put the shaft between two V blocks with hump high in the center. Press it gently down.

Hi: You could try a thread file. They don't care if the thread is left or right handed. You just need one with a 1mm pitch, the files I have, have 8 different pitches on them. 25 TPI might work OK.

I cant remember the thread size but it is a 1mm pitch left hand thread

The thread size doesn’t spring to mind, but there may be a suitable thread file available. Just an example here: http://thetoolshop.shoprw.com/Thread-File---Metric-P-19471.html Dave W

Check all the things mentioned above before re-cutting the thread. If you do need to re-cut it I had no difficulty finding a left handed tap, and I assume a die would be available. If you get a split

Thanks Jerry, Good point on the reversed thread didn't even cross my mind. I've given it a clean and re-grease. It's running much smoother but it does appear to have a bit of a bend in it when I wind

Kallum, You do know this is a left-hand thread, so tap and die need to be left handed. Also, the cross slide may not move freely if the locking screw is still engaged. Before even thinking about

On the unimat SL I just purchased it looks like the thread has been crushed a bit. This? makes it difficult to use the . I'm thinking of running a tap through the cross slide support and a die over

So I traded a guy a motor that would trip the breaker for one that wouldn’t. Since I am an electronics tech and I have overhauled a half dozen U90 motors I was confident in the swap. Noise
