I'll add on. I also need a short tool rest with a 25mm post, but I think a 1" will fit the banjo (its a HF 34706). I have seen some on the web but they want more for them than I'm willing to pay. If you know where to get cheap ones, let me know. Or, if you have an old used 8" or 12" you want to get rid of, let me know, I'll cut it down.
