Myford VM-D

[Alan Worland 1Participant @alanworland1]

I use the above milling attachment on my ML7 and it works great, I use a flycutter, tipped end mills and a variety of HSS endmills in the range of collets I have and I find it very accurate, BUT, unless I am very clever at planning my maching (not going to happen!) I find I end up fitting/removing it more than I should!

Seeing Terence Hollands article recently in ME on building a Fairlie Complex I see he has fitted a similar attachment to the rear of the bed and powered it indeipendantly.

I thought what a good idea, I could leave it in position ready to go.

I need a bit of guidance with regard to motor power. I would like to keep motor mass to a minimum, on account that it will all be hanging off the back of the bed, but have enough watts available to carry out my typical machining.

Any thoughts on motor wattage to go for? I have a couple tucked away in the loft (for future projects!) which I shall dig out for investigation.

Would it be possible to hang the motor on the wall of your workshop, instead of the machine its self. I'd think if you had a motor of 1/2hp or more 1450rpm (4 pole), you'd be fairly right. Ian S C

That sounds a good idea to remote mount the motor, but not poss where it is! 1/2 horse would be quite large motor as I only have 1/3 fitted to the lathe

Thanks for your response – I shall work on the idea for a while I think.

The self-powered Amolco attachment I used when I had a Myford had a 1/3hp motor, which was quite powerful enough.

The 1/2hp Hoover cap start motor on my compressor is about the same a the 1/4hp motor on my drilling machine, and the 1/2hp motor on my bandsaw is considerably smaller than either of them. A 1/4 or 1/3 hp motor would be OK, if you are like me, its a case of using whats available. Ian S C
