Denford Software & Machines

Hello

I ended up with a Taylor chuck in very good condition with three sets of jaws. A rare find.

The history of the Taylor chuck can be found here: https://www.lathes.co.uk/taylor/page6.html .

The back plate wouldn't fit the Denford, so I made one.

The back plate was made of cast iron.

I found that slow speed (60rpm) worked best. I found an almost flat HSS tool with very small angle of approach worked very well.

The dust gets into everything. I placed a magnet near the tool cutting edge to trap a lot of dust. I partially stripped the lathe down to clean the dust off (it is very abrasive when mixed with oil.

When I machined the spigot that aligns the back plate to the chuck, I heated the chuck in the oven to about 50 deg C. I machined the spigot on the cold back plate to a close sliding fit. When the chuck cooled, it clamped onto the spigot with just the right amount of grip.

Measured runout of the finished chuck was less than 1/2 thou inch.
