QCTP Disassembly - How To?

[Nogoingback]

I recently bought a wedge style Phase II QCTP and thought I would disassemble it to clean, lubricate and check it over before I use it. Has anyone done this?, and if so what do I need to know?

Assuming you have the piston type, see the attached PDF. If it's the wedge type, just keep unscrewing and the core will come out.

well, he said wedge not piston.
There's nothing to say, it easy , just do it, it's all self explanatory as you pull it apart. Clean it and grease the screw (or helix)

Thanks, both of you. I'll just give it a try.

A 6" vise is overkill for a RF45 style mill. A 4" is more appropiate for that size mill & IMO 5" max. I have a 5" GMT vise on my PM45 & it's slightly too big. Not enough Y axis travel to make use of the 5" full capacity. Better to save your money rather than getting something too big & most importantly the weight. I take my vise of the table quite often, a 6" is still light enough for me to be carried by hand but I'm glad I have a 5". I also have a 4" vise as well. I prefer the 5" though.

But those GMT 6" Premium vises are pretty nice. I'd love to have one but don't need one on my current mill. But if you plan on upgrading to a full size knee mill in the future than the 6" will be perfect.


Here's what the 5" looks like on my mill.



I couldn't even complete this cut without my bellows & DRO scale getting in the way. Not enough Y travel & the 5" vise is not even maxed out.



Here's what a 6" vise looks like on another PM45 (gt40's)
