What horse power is the motor, there is a list of values in the Workshop Practice Series No. 24, Electric Motors in the Home Workshop by Jim Cox.

For .25 hp it's 10 micro farad loaded or 7.5 lightly loaded.

Normally the belt cover spring clip goes inside the headstock to stop any rattles.

UNF 12 x 28 which is only 0.007" bigger and 0.2 pitch difference

Just for interest there is a design for an ML7 lever feed tailstock in MEW 16 page 30 .

In my downloaded catalogue from 2019, the drawings are £20 and set of 12 castings £468.

I dare say the prices have increased since.

There are free plans on this site for a clutch

It works very well

In the Arc advert if you click on the ' More ' tab at the top right, there is a description of how the vice works.

Andrew,

On my Flott high speed bench top drill, the pulleys are easily swapped over, a pin spanner releases the pulley from a slotted taper.

Hi Dr_GMJN,

Try " Intoducing model traction engine construction by John Haining "

Just Googled VCGT carbide insert angles and it came up with 35*

Check out stauffer grease cup on the internet.

When I made mine probably 18 months ago, used Gorilla Glue Clear, no problems so far. Left the dressed belt side out gluing on the rougher side. Best lathe update I've ever done.

Further update.

Somewhere along the line of building and installing the ELS I missed or skipped the Part 7 Video by Clough42 see

( https://www.youtube.com/watch?v=10Ketpqq-eM )

on metric and hybrid threading. In this video he cuts imperial threads on an imperial lathe using a thread dial indicator ( ie opening and closing the half nuts ) and metric threads leaving the half nuts closed and reversing with the forward/reverse switch on the lathe itself.
The reverse function on the ELS control box he uses for left hand threads.

So problem solved I think.
