Hi there.

Bit late joining this thread but suddenly had to remember how to cut threads on a lathe the other day.
One problem was that previous users of my M300 had decided to loose the small gear wheel. pin and bush on the DTI

Looked for a replacement in the usual places including Harrison's themselves but they were wanting silly money.BTW I guess you will all know that small Harrsion lathes are all sourced via Taiwan.

Somebody recommended HPC Gears in Chesterfield and they suggested that I try a 16 tooth gear to run up and down the imperial 4tpi lead screw. Part No. ZPG2-16

I turned up an new bush and drilled the nylon gear to accept the 1/8"dia pin.

(Is it my imagination or is this device a mixture of imperial and metric measurements?}

Works just fine for others in a similar boat.

Gear wheel plus post and packaging and vat was £22.

Somewhat better that the £100+ prices I had seen.

Cheers

Malcolm

Don't know if I am a bit late joining this conversation but I purchased a fully refurbished Myford Super 7 from Myford at Mytholmroyd about 18 months ago.

I specified a 3 phase variable speed motor and control panel but no screw cutting gearbox. I do have the full set of standard change gears if I want it to cut screw threads.

I am very pleased with it. Only reservations would be the very small spindle internal diameter and although you can use as a milling machine it is not best suited to this.

in comparison with the experience i had from the purchase of a Chinese look alike Bridgeport vertical miller ( which was horrendous to start with) I would stick to UK machines anytime.

Hi Richard 2

read the following. Almost identical problem, not helped by the supplier!

Thanks Vic. I am certain it will come in useful.

Any comments on owning a Super Major mill as per my above post?

Hi Raymond

I am even newer than you. First Post!

I am interested in your experiences, so far, with the Warco Super Major.

What are you using if for and are you pleased with it?

Any other information greatly appreciated.
