tailstock Cam lock kit and F/O/R switch change
HI All! I've been making some parts lately and have had some luck selling them as well. Enough to buy some new hop-ups for my 7x12 Cummings lathe :-) My F/O/R switch is acting up, and I'm thinking that I'd rather have a rotary type switch instead of a toggle, like the one that's on the micromark 7x14... anyone make this swap? I'll probably just wind up going with a stock replacement, unless the swap is easy? I'm also thinking about a Tailstock cam lock kit. I see LMS has them for $30... Does the cam lock kit rally get the tailstock clamped down tight enough so it doesn't move? will installing this kit throw off he alignment of the Tailstock? My TS is perfectly aligned right now, I really dont' want to go through that trouble again of lining it back up... or worse I really don't want it to be thrown out of alignment higher or lower :-( thanks!

Can't help with the switch but might help with the tailstock. I did not use a camlock, instead I made another nut higher than the original and drilled and tapped in several places for a lever handle. I made the nut about 1" high I think,I'm not near the shop to look at it.Then tightened the nut and marked it for where I wanted to have the handle.I drilled and tapped for 1/4-20 thread at my mark and also another at the left and right of the first tapped hole. The second and third tapped holes were for just in case I might need them to tighten or loosen the tail stock.This worked well for me so I did the same thing on my larger lathe,10x22.You won't need to touch the tail stock ,just make the tall nut and lever handle. You can use round stock or hex stock which I used.Round stock would need at least two flats
milled so a wrench can be used if needed.I can only think of a couple of times I needed to use the wrench to tighten the tail stock. Both times I was drilling a large bore in aluminum bronze and the tail stock slipped a bit. mike

I didn't make a camlock. I used a ring spanner, the
type with an angle to the handle for hand clearance. Used upside down, it does
the job perfectly, clearing the compound slide and staying in
place.

Swapping switches is a simple soldering job if you
know how to work on circuit boards.� The TS camlocksI made for my 7x
lathes work very well, and I'm sure the LMS ones will, too.� LMS is a very
reliable bunch.

I have the kit while the install could be a little fiddly...to a point of annoying the result is great I also have drilled and tapped the 1/2" hole to a 1/2" NPT to accept brass insert so the shaft of the cam can ride on wider bushing type of a hole...worked for me. no miss-alignmentwasexperiencedalthough I do take thetail-stockon and offfrequently

Ellis, I never thought of using a ring spanner,good idea.No work to do with your method. mike

Mike,
When I had my H.F. lathe, I bought a 17mm combination wrench at a flea
market, then cut it about in half with an abrasive wheel. The box end of it is
bent at an angle, and it hangs on the T.S. clamp nut. You can usually
loosen/tighten the nut w/o actually removing the wrench at all. If you do have
to move it, one additional swing will do the job. It’s nearly as fast as a true
cam-lock T.S., and clamps better. At least, it worked better than the cam-lock
setup on my Micro-Mark 7X14.
