[modeleng] Re: Smokebox Door Hinges (again?)

Hi Harry,

It's a lot of work, but could you make a semi sacrificial lathe fixture to 
hold two hinge bars at correct locs and turn the backs of them to the same 
radius as the door?

I'm thinking of a block or plywood disk with slots for the bars and holes 
for screws through the bar rivet holes. Flathead screws through the disk 
with heads on the chuck side would hold the bars to the fixture. The rivet 
holes could be tapped (at a smaller dia than the rivets will be) to fasten 
the bars to fixture even as the screw ends are turned away (partly) with the 
waste.

You could get the back profile exact with this method and just clean up the 
front bar faces with die grinder and files parallel with the backs.

The other way would be forging the bars in miniature I would think. Could be 
done but very fussy and may mark the door. In addition, locating the rivet 
holes might be a chore afterward.

Cheers Jeff Dayman
