Locking carriage/slides on a manual lathe
 

Awl--

I have a 13x40 Enco, but set up really nice--x,yDRO, snap handle 5C, Aloris,
cam-lock chucks, new bearings, really kept nice by the original owner. You'd
almost think it was American-made.
In fact, the owner did so much work on it, he taped "Made in America" over
the "made in china" tag! :)
Also, the bed is closer to 50", past the nose!

However, I don't see the traditional lockdown screws on the carriage or
cross-slide. Am I just missing something?
Is it possible that some lathes simply don't have these?
If this is so, what do one do? For the carriage, I could see clamping
blocks on either side of the carriage, down on the ways.
Improvising a lockdown on the crossslide seems more elusive.

Any idears??

Enco has a lot of manuals available for download. Did you look for
the one you need? It should have drawings and a parts list.

My EMCO lathe cross slide has a screw on the side that will press the
gib tightly and this will lock it. Maybe yours has this, also. I
replaced the origional screw with a long socket head cap screw so I
could find it when the compound is turned so it covers the area.

As one would expect on a lathe 40" between centres.

If it has a separate feedshaft, engage the halfnuts to secure the
carriage for facing.
As for "traditional lockdown screws on the cross-slide" Any examples?

Well, by "traditional" I mean an easily accessible screw(s) that will lock
it down. Paul above cited his emco on the gibs, which is how I think
Hardinge chuckers work as well. The Clausing Colchester roundheads have
lock down screws--not sure if they work on the gibs or elsewhere.

My Enco 1024 has a square-head bolt head at the right rear, top of the
carriage to lock it down.
The manual for the 110-3110 seems to show one on the near side.
What model do you have?

OK--
Found the problems.
My model is a 110-1340 (13x40).

Actually, your reference to the "right rear" got me looking a little more
closely back there. And in sleuthing locking alternatives, I was going to
run a round rod behind and along the bed, and link this rod somehow to the
carriage, to create a stop of sorts.

I then noticed holes in the *back* of the carriage (that rests on the back
ways), which take 8x1.25mm screws, which will lock on the vertical face of
the back ways. You would *never* see these by casual inspection.
So the carriage problem is solved! And not a bad way to lock the carriage. I
am going to put nylon between the screw tip and the ways.

As for the cross-slide, it seems that the Y encoder/glass is covering these
screws, which apparently tighten the gibs.
However, by bolting aluminum block to the carriage where the follower
normally bolts, and suitably threading for add'l screws, I can basically
lock the slide similarly, just from the other side, with the screws hitting
the outside of the slide, not the gibs. But with the same effect.

I am in fact extraordinarily happy with this lathe (1992
vintage)--positively spoiled by the Aloris tooling, DRO, and snap handle, as
well as the cam-lock chucks.
Not the brute strength/rigidity of the Clausing Colchesters I've worked on,
and I could nit-pick a bit here and there, but overall a pleasure to
use--largely cuz the previous owner got rid of all the bugs.

Soon, tho, I'll be getting a 13x40 CC real cheap (snap handle too!), but
which will need some work on the carriage. It will be interesting to do A/B
comparisons.

Oh yeah, did check the manual, as per one poster. Not at all helpful, but,
pretty hilarious, linguistically speaking.

Appreciate the feedback.
