I had a Hozan spoke threader that I bought to chase/clean-up the threads on some 36er spokes a couple of years back. It never worked well, no matter what I tried and I even had Hozan replace the cutters under warranty and it still worked poorly . . . . . and I know others have had the same experience with this tool. Not sure if there is something now that is between the $100 Hozan and the expensive professional threading machines like Phil Wood?
So what type/brand are you looking for?
I may be mis-remembering the price. It is entirely possible that user error is responsible for my and others trouble with the Hozan. It wouldn’t be the first time that this upright monkey didn’t use a tool properly and blamed it on the tool. I do recall that its difficult to convince a freshly cut spoke end to go into the rollers. I think you have to chamfer the edge more than a little to get it to start. . .Others on here might be able to verify this quirk of the Hozan.
