Scarebird, is it safe?

There is very little difference between your drum brake spindles, hubs,
and the ones used in Kelsey Hayes disc brake systems.

Pauly v.100 anyone with a brake laythe could turn those hubs for you if they're willing to rearrange the tool post for a hour. I got shop access etc..
and could handle it for you but the postage would kill. :(
Good luck
