How to mount a myford vertical slide

[jon white 1Participant @jonwhite1]

Hi, my first posting. hope this makes sense. I bought from Amadeal a AMA240x400 lathe,and thought it had Myford, but what it has are 2 parallel slots at the edge of cross slide,so what is the best solution apart from using my tool holder LBSC style,cant build big things wanted to make a 2.1/2"gauge engine but I c`ant drive now as I have epilepsy.

Any sugestions

milling in the lathe,that old chestnut!

Drill some extra holes in the base of the vertical slide and/or use some milling clamps.

I have had both an Emco Emcomat8.6 and Warco 280 that also have the two slots and have not had problems mounting my slide in over 30yrs

Since Myford stuff goes for a premium you might be able to sell it and get the right one, even swap it with someone who couldn't get a Myford one and made do with a new style one.

You could mount it on a plate using countersunk screws up from underneath through the existing holes and clamp it down with holes in each corner. This style of lengthways slots is quite versatile in mounting position and possibly better than the standard cross ways ones.

Myford did a raising block for vertical slides like this:-

I'm not suggesting you buy one, unless you can find a 'cheapie' but should give you the right idea for an adaptor plate.

That's what I've done with my fixed slide. Two holes at right angles to the original pair – makes the slide more versatile when using it to hold a milling spindle.

Hello John,

Welcome to the forum, I see you've had a few decent answers already.

Hallo Jon – well anyone building 2.5" engines gets my support – even though Bazle has already suggested my solution.

I purchased a Chinese vertical slide (which is heavier built than the Myford version) for my Super 7 – so a reversal of your problem. But the solution is still the same in my view – a 1/2" adaptor plate to match the holes/slots in the lathe to those on the slide. Mine has developed other holes over the years as various other bits (that don't easily clamp to the cross-slide) have appeared – vices, boring supports/steadies, angle plates etc – so it's a useful thing to have anyway.

Good luck with your engine building – great scale/gauge to work in!

Regards,

IanT
