Hi, I am trying to restore an old Myford lathe I dismantled 15 to 20 years ago. I believe it is an ML2 or ML4. Unfortunately I did not take any photos at the time of dismantling! Luckily, not typical of me, I stored all the bits safely and now after cleaning, repairing and painting I am trying to rebuild the machine. Even after studying old pictures of the machine I cannot locate and secure the counter-shaft with the three flat belt speed change pulleys and the pulley that links to the motor.

The obvious spot does not seem right to me. There are two 3/8in holes in the tray but only a square hole in the bracket. There are two further 1/4in BSW holes in the bracket that don’t seem to line-up with anything on the tray or headstock. Have I in fact lost a packing piece that fits between the ribs on the underside of the tray and does a bolt go through the rectangular hole to hold the bracket in place?Hi, I am trying to restore an old Myford lathe I dismantled 15 to 20 years ago.

I had hoped to attach some pictures to this post. Can someone explain how this bracket is secured?

Hello Don,

Welcome to the forum.

I'd be only too glad to help you having had many years use from my late father's old ML4 but I really can't get a mental picture from your description, photos are all really

I struggle every time I want to post photos here, it really seems to be tediously difficult to do so and I hope someone else can give you the step wise instructions you need to do it.

I've tried to go back over the steps involved but then lose all that I have written in going back to check something which means starting again.

After that, sorting out your bracket should be a doddle! If nothing else it will bump your query to the top of the list again

Brian

Hi, I have solved the countershaft location and fixing problem. It does go where I thought it should but I think I was looking for something more sophisticated in the fixing and adjustment line!

I have another problem now with the tailstock.

I think the lathe is an ML3 but I am not sure as there are no markings on the bed. I would like to see some pictures of the dovetail mating parts of the tailstock to the bed that probably fix to the offside of the tailstock and are similar to those on the nearside of the tailstock. I reckon I am in for some copious filing and hacksawing but I’d like to see what the manufactures parts looked like before I start grafting. I appreciate that the tailstock lock is on that side and is probably simply a made up nut fitted with a lever that fits on the protruding stud shown in the picture. If anyone has a model similar to the pictures of mine I really would appreciate a view of your tailstock clamping and slide-way parts and perhaps a suggestion as to the model type. I will read the instructions on creating an album and upload some pictures

Many thanks, Don

In your "what goes here" tailstock photo is a clamping piece – rather similar in shape to the toolpost clamp – and, of course, a threaded piece with a lever attached to tighten and lock the tailstock to the bed. Sorry I can't give further details as I no longer have that machine.

Hi, thanks for input it all helps to conjure up a picture of what I have to make.

Thanks again Norman, I have just been painting the tool post clamp when I thought I've already painted a piece this and wondered what the devil it was for. Then your words came back to me and there it was hanging up in front of me! Another problem solved. Only the motor to mount now and make up a 'serpentine' flat belt for the countershaft. I have the original leather drive belt.

Hello Don,

Norman was quite right in describing the rear shear fitting for the tailstock, it was from memory a divided fork shaped component in cast iron with the roughly 1 inch wide lugs roughly shaped to fit the shape of the bed dovetail. A pretty crude thing really but all it had to do was clamp the tailstock down on the bed .

I have attached a picture from the handbook of the whole lathe

It is all back together now but I need to make up a countershaft flat belt before I can run it. I appear to have bit left over though and I don't know where it goes! I don't think it'll affect the running of the lathe though.

What will be a problem is the 3 jaw chuck, it feels as though it is full of sand and it is hard work turning the key. The scroll appears clean as are the teeth in the jaws. Any advice on dismantling and cleaning the chuck?
