I have long wanted a T-slot plate (table?) for my QCTP. You may have inspired me to actually do it. On 1/21/23 20:13, Jim_B wrote:

Spindle take-up bearing interference with the gearbox engagement lever on my 10k
Also - there are thick and thin versions of the spacer washers. You need to make sure you have the thin ones. McMaster-Carr has pretty good drawings and explanations. The stack for my 9A ended up only

Magic Rust Removal Fluid......
It may be that some of the rust color on the chuck was actually oxidized oil and not rust. If so, that is a good thing for you and your chuck.

14-1/2 spindle nose and taper
Now I need to go double check - I think on the 9As they left off some of the large end as well, which is why a standard mt3 center sticks out so far. Probably to keep from needing a larger spindle thr

If they had used the smaller end it would have restricted the size of the spindle through hole.

14-1/2 spindle nose and taper
I'm really not getting this argument. Shouldn't it fit both ends and everywhere in between and a little beyond is ok? And how could anything other than putting it in small end first ever work?

That is fine and good and what I would also recommend if that is all you need. The drawback is that it will stick out farther than necessary and may make it difficult for the tail of a dog reach the s

New South bend 9A Owner
The lube that goes in the cone pulley lubricates the motion of the cone pulley around the spindle when you are in back gear. The spindle bearings have their own lubrication system. My big question is

80/63 is such a close approximation of the exact ratio 100/127 that you can probaly ignore the difference. 100/127=1.27 80/63=1.269841270

Note that 28 is half of 56. You can double or halve either stud or screw gear and move one row on the chart. That means you can run 56 on both stud and screw and move down to the C hole and get the sa

What's this?
A hand-lever cross-slide? That would be a relatively uncommon production device. It doesn't look to me like it would replace either the cross slide or compound on either of my lathes.

Motor pulley for two-step counter shaft pulley
I just acquired a two-step counter shaft pulley for the 9-A in my garage. I've been wanting one, just because, for some time. They have generally been more expensive than I want to spend on something
