So I purchased the Scheppac Wet Grinder Wood Turner attachments based on price as Tormek is to me greatly over priced.
This is the Scheppac jig mounted on the bar.
I had a piece of steel block which was almost ideal shape, a second hole drilled for the jig shaft of the main tool holder jig.
A bit of shaping to round off the edge nearest the grind stone a spot of linishing to brighten it up and round the edges.
I left a shoulder as a buffer.
Instead of retaining the two locking rings I drilled and tapped a 6mm hex head bolt into the block to lock the position of the tool.
I used a piece of Modwood, off cuts I had been given, to reduce the 17mm hole already in the block to 12mm and this gave a better sliding surface along the bar. Modwood turns easy and has a great instant finish to it, can be shaped well and drilled and tapped. Its a mixture of wood and plastics mainly used for decking.
Fits, looks and works real nice.
Below the two parts sitting side by side as a comparison.
I was doing a web search for something or other in regards to spindle adapters for the Nova 3000 and came across Nova's listing which indicated they had an adapter J 1 1/8" x 12tpi which is the spindel thread of the Myford and is listed as such. An email to Trend Timbers and Adrian responded they had one in stock it arrived today and fits like a glove a test run with a Nova chuck for true running and all is well.
