The great chuck runout debate

**rsser** · 29th July 2009, 07:05 AM

Just ordered a GPW Gen 3 chuck and will report how it goes.

A 4" job that'll take VM 90/100 jaws as well as T/tool. The VM jaws have to be drilled out a mm.

$150.

There's a deluxe version with multiple jaws too.

Added: and a 110 mm version.

Ern, Be looking forward to your comments on it. Shame nobody makes a big chuck ie 150mm old SN2 I have three of them and they are my major work horses. Perhaps they did not sell well, who knows.

Well there's still the VM 150. Nice chuck but not nice price. (Website says it'll take VM100 as well as 140 jaws which is a departure for the firm).

Gary Pye still has some Titan companion chucks in stock - more affordable but of course only 5". Interestingly the T/tool 2008 catalogue said this chuck was under 'redesign' so maybe there's a replacement on the way.

Correction: the VM website was wrong. The 150 does not take VM 100 jaws.

I dropped in to GPW yesterday for a couple of things and had a look at the new chucks while I was there. They look really good. I'd certainly consider one if I were buying a new chuck.

Yep, seem well made. No burrs. Full backing plate with two rows of indexing holes. Jaw numbers stamped on chuck face. Proper tightening direction. Only dislike on first look is the square hole gear drive so you have to have two tools hanging around the lathe.

I'd be willing to take your old Vicmark chucks off your hands Ern, for a small fee of course

Sounds good, square hole two tools PITA. But clockwise tightening

now thats something I can appreciate.

GJ, no worries. The fee will be $300 plus postage. I'll let you know my account details

Agreed, Hughie. The SN Deluxe is still my favourite chuck for the $s.

The Titan went off at a tangent and only made sense if used with its dedicated powergrip jaws.

The big Vicmarc looks good (and will take some seriously large jaws) but, as Ern said, for a serious price.
