In Tunbridge Wells,England,famous for turned wooden items and other wooden items,the turners would get their wives to turn the lathe while they threaded the wooden boxes and their threaded lids! They used a SINGLE cutting edge cutter that was hollow in the "V",and sharpened on the inside of the V. The cutter looked similar to a V carving tool. The internal cutter had to be turned at a right angle,of course. These type cutters were referred to as soft wood type cutters.
Re:Thread combs; I sometimes tend to use old names for certain tools,coming from 39 years in a museum.
It would have helped in the old days,if the chasers had had their teeth angled to match the threads they were to cut. But,they were made straight vertical. When I make a chaser,I mount a comb blank in the tool holder. I put a threading tool in a short piece of round stock with the threading tool pointing straight outwards. Then,I run the blank past it with the QC box set on whatever thread I want. I take several passes until the thread is cut across the end of the chaser. That way,I at least have SOME angle to the teeth. All my old chasers are vertically cut,though.
Hope this makes sense. I'm not doing too well with descriptions this morning.
