Hi all, Assuming I had the choice between an older (but good condition) emco original chuck, or a brand new sherline, for the same price. Which should I get? Thanks!

Here is your saw, phot attached. Also:?https://www.youtube.com/watch?v=N44c_Y2VwqA

Pretty nifty! I've got a Dremel scroll saw, but it's relatively huge, and takes up quite a bit of space. Also relatively heavy! About 8 or 10 times the volume of a Unimat, and probably 50 or 60lbs. It

This Jig-saw or fred-saw came this week with my new Unimat MK2a. I was not able to find any picture's online and made some to share.

Apart from the fact that you don't need absolute concentricity with a four jaw, since, as already noted, the whole point is that you can adjust for any eccentricity, the original Unimat chucks didn't

Hello John: Look for one of all steel, not die cast pot metal. I tried a pot metal chuck on a Unimat 1 ( the aluminum/plastic 12 volt toy ) and would not trust to hold more than wood. Spend the money

For someone here who wants an M12x1 4-jaw chuck, go to Ebay advanced sold items.? You will see here sold Indian 4-jaw chucks and Unimat 4-jaw.? Unimat cost money.? So unless you want to have Emco

Is what I did. LOOKS really good. Haven't finished the refurb, so can't tell how good it really is. There is enough metal there you could skim off much of the back of the chuck, and make a? back

So is the idea to buy the cheap made in India 4 jaw chuck on Ebay, and not Sherline?

Richard, Runout on a workpiece clamped in an independent four-jaw chuck can be corrected by adjusting the jaws. It therefore doesn’t matter if the body of the chuck has a small amount of runout.

Quality chucks are available from sherline.com and can be ordered threaded to fit M12 x 1 DB/SL lathes. The price for a 2.5" independent four jaw chuck, threaded M12 x 1, from Sherline is $131.04. The

Thanks Dave. As good a quess as any.

Dick, I bought the after market one as it is cheap, I am sure it will not be anywhere near an original. Dave

Brian, Thank you very much, that suits my budget, I bought it. Dave
