They are not. In particular the table construction using aluminium extrusions is a bit flexible. It takes some care when twiddling the handle to get a nice even cut, but, apparently, it can be fixed.

As with the previous topic, with the failure of a jaw on a unimat 4 jaw, which also happened to me, I had to lap the new jaws in to get a sliding fit - I don't know what material the Indian made jaws

These things are cute and probably vastly more rigid than the unimat alternative. Get Outlook for Android<https://aka.ms/AAb9ysg> ________________________________ Sent: Tuesday, September 17, 2024

You are probably right, but it doesn't hurt to ask.

Keith, I've been trying to draw this out to be able to use an end mill (90 degree angle obviously) to cut the notchs between the 'blades'. Is this how you envisaged it? My 3rd attempt, as you can see!

I don’t see the pictures but I might be interested

It will probably be easier to find a whole chuck than just one jaw. Get Outlook for Android<https://aka.ms/AAb9ysg> ________________________________ Sent: Tuesday, September 17, 2024 2:12:05 PM To:

I have a Proxxon MF70 vertical mill for sale.? I got it from a collection and it appears to be new.? I removed it from the box and assembled it as shown.? I put power to it and it ran.? For

Hi Carl!I use a threaded left hand bolt or rod from the hardware store as a master. Diameter is irrelevant as it’s the lead you are after, not the diameter.Dick

Hi Gang: Since I received a thread cutting lathe (Smithy Granite) I have tapped thousands of hole, but only set the lathe up once for threading. And that was to guide a tap through an intermittent

Depends. There are some holes that are too small to single point thread on some lathes. Granted, that well done single point is much more accurate than most taps and dies. Get Outlook for

Why spend money on taps and dies you when you can cut your own by single point thread cutting? You will also end up with a superior result if you are careful. A challenge is also good for the brain

Robert, The chuck looks dirty in the photographs, as if someone had turned wood and the sawdust mixed with the grease in the chuck. Clean all the parts thoroughly then apply a thin film of oil to the

Thanks for the reply! It might come to that if I don't fine one. -Brad

That looks like the made in India 50mm for the db/sl. I have the same one. It is reversible but i found this chuck to be really sticky when i got it. i wound up lapping it in with metal polish for a

You're not reversing the screws, are you? The jaws reverse but the screws may only easily go in one way. Just a notion that comes to mind.

Rob: The jaws certainly LOOK like they should be reversible.? Maybe there's a burr on the back of the jaw that stopping you from reversing the jaw?? When zooming in on your last picture, it almost
