Re: C to B to A Conversion


Hi Gerald,

The model "A" apron I bought on eBay had excellent half nuts, so the ones I refurbished are not needed. I spent about 6 to 8 hours building the holding fixture described in the HSM article and learning how to braze cast iron. I found that furnace patching cement is useful in building a dam to keep the brass from running out of the area to be repaired. If you send me your old half nuts I will send you a "renewed" set for $25.00 S&H included. I tried them out on my lathe while still in the "B" configuration and the only play I could detect was due to the leadscrew shifting in its bracket.

There is a difference between model "C" halfnuts and those for B or A lathes. The interlock mechanism that prevents the clutch drive from being engaged when the half nuts are engaged and vise versa depends on an adjustment (filing or grinding) of a perjoggin on the side of the bottom half nut. These "C" half nuts would need to be fitted to your "A" or "B" lathe.

Would you have an extra pair of half nuts? I could use a pair so I dont have
to repair mine.
