Hi,
At last I've stopped moaning about the weather and spent some quality time in the garage today for a change.
Needing to cut a key-way into the new counter-shaft I didn't fancy grinding up a lathe tool and using the carriage to slowly cut the key-way; instead I ordered a new 3mm end mill which arrived yesterday but I then needed a lathe so today I've temporarily installed the new Servo Motor onto the Clarke. It's a case of lathe heal thyself.
It's not easy rigging up a remote motor onto one of these small lathes but I've just successfully done it and now hopefully I'll be able to cut both a key-way and circlip groove?
First job was to measure the bore of the head-stock mandrel finding this to be 0.802". Using the Record Power woodturning lathe I then turned a hardwood bush with an outer diameter of 0.806" and through bored it at 10mm to accept a threaded rod. I had an old aluminium pulley in stock which I could press into service.
The hardwood bush at 4" long was drawn into the mandrel using threaded rod with washers and nuts ensuring a very tight fit. Also pressed into service was a Rawlplug type insert; the short taper was removed and this was attached to the threaded rod then the threaded rod was tightened nipping the pulley which should suffice for light cutting; at least the lathe is running once again. The motor was attached using original holes in the lathe head-stock casting ensuring it was safe and secure; the belt and odds and ends I had in stock.
Once the key-way and circlip groove is cut then I can proceed to install the new counter-shaft and make a permanent job of mounting the motor. As expected the Servo motor is spinning the chuck without problem so I'm keen to see how it performs once fully installed.
Kind regards, Col.
