This is on the classified ads. I thought I might get some comment over here.
My opinion from looking at the picture: I think it works something like a rivet squeezer, it pushes spoke tenons out of their felloe sockets, like this:
Could it be a press as Mark suggests, but to push the ten on down to allow a spacer to be placed between the shoulder and the fellow?
Looks to me like it is meant to be mounted on the wall. Long handle placed in the socket and when pulled down applies an awful lot of force. Certainly more force then needed to push out spoke tenons, most I have seen fall out!!!!!
The comment in the classifieds "I have dies that go with it" indicates to me it may be used to punch holes in the steel fellows to accept the tenon.
Just my impression when I first saw it.
Kevin, I missed the part about the dies that go with it, in that case you may be right, since (at least on my Kelsey felloes and Hayes felloes the tenon holes are belled out like they were punched.
Can we see pics of the dies?
Yes. It would mount on the wall, or a post. It would be used to tighten loose spokes by deforming the metal felloe around the spoke tenon. I will try to post some picture of the dies, but won't be able to do that until monday.
