Mounting Taylor Chuck

Post by dazz » Tue 06 Jul , 2010 10:52 am

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: http://www.lathes.co.uk/taylor/page6.html .

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

Bevel gears drive the scroll plate.

The back plate mounts on the back half of the chuck. The chuck is split along the centre line of the bevel gears. The join line is practically invisible (accurate machining)

The scroll is a dished spiral.

The scroll fits within a reasonably complex casting.

The Taylor chuck is bigger than the standard one, but not too big.

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.
