Making a Carriage stop for a lathe

Not a Myford, but my mini lathe.

I have two carriage stops for my lathe, one is std and makes a clutch slip in the apron. The other one I put on the carriage stop which operates a micro switch to add a braked stop from the vfd for when screw cutting.

I apreciate that one should not put items for sale in the threads but as the subject on hand is stops I thought that I would cheat ( If I can get away with it!!) & say that I have one of these for sale for £ 80-00 plus P & P

It is quite heavy

Here's mine. I thought I'd avoid any flack by not showing the 45 second video I didn't make of me drilling and tapping one 8mm hole.

This is my version for WM250

Details of build *** HERE *** but no video!

For a mini-lathe it is not too difficult to wire a micro-switch into the chuck guard stop circuit as an over-run switch.

Stops that switch the motor off....

Fine in theory but I would be wary of using it with a VFD as it would seem to emulate the Emergency Stop action, not recommended for the sake of the electronics.

At least I would suggest seeking the manufacturer's advice before making any such system.

The switches on machine-guards are to prevent you starting the machine with the guard open, not for stopping it.

This is my answer to a gearbox fitted Myford S7 making use of the tapped hole provided for the oiler. It has provided satsfactory service over many tears.

Hey Greensands. That looks great. Not seen one like that before.

I have the very same one did need to strip it and clean it up for the adjuster to operate smoother than supplied

Greensands:

That's a very nice looking machine and ingenious solution.

On mine, the corresponding hole is for the detent grub screw ie FWIW not an oiler.

I modified the stop on my Warco 290V to make it quick to set and release.

Very nice Nigel may have to do that with mine looks easier than having to fiddle with the two bolts underneath the stop assembly

In case it's not clear from the photos, I used the quick release mechanism from a bike front wheel to make the clamping mechanism. Much easier than two hidden bolts!

Hi again Greensands. I have been working on my Myford tonight. If i had the stop where yours is fitted , then i could not engage backgear.

One of my requirements for this sort of thing is that tools are not needed for use. I've posted my current stop, but having made it from aluminium it's spread and becoming less effective. And I've never used the adjustable stop because it's not accurate.

So the new one will look like this:

and

Mm interesting. Will like to see the finished product.

I like the look of this design. Grab a couple of pics if/when you make it and it could be a good little article for MEW....

Here's the Carraige Stop I made for my Myford 254. No automatic lathe-stopping or anything, it's mainly to prevent me running into the chuck when roughing-out by hand. No changes made to the lathe itself, it just clamps around the top and bottom of the ways. It consists of a holder with a clamp on the lathe centre-line, with 4 different length rods (adjustable) to set the actual stop position (which acts on the centre of the saddle).

First picture shows the holder with clamp, and the four stop-rods.

Second picture is a close-up of the holder.

Third picture is the carraige-stop in use, with the saddle stopped by it.

A simple adjustable stop on my Clarke lathe. The excess length disappears into the drive housing on the left. Next job is to add a fine thread button/lock nut at the contact end.
