Default Cam lobe be repaired???

Recently, a couple buddies and I were bench racing. Seems "John" damaged one cam lobe when a lifter twisted 90 degrees in tray, and wiped out just that one lobe.He asked whether companies like Comp, Crane, Isky, Can Motion, etc., are willing to repair a single lobe on one of their own grinds? Guess he figures repairing the one damaged lobe is cheaper than a whole new stick. I told him that time (and $$) are in the cam grinder set-up, and may not be as cheap as he thinks. I admit, I really don't know what to think on this one. ANYONE know for sure? Thanks

Cam is machined from solid billet, can't be repaired. Get a new one and all the associated parts required to repair any damage found.

There are some machine shops that can build up the lobes via welding and then regrind but the cost is more than purchasing a new cam.

there was a scammer on craigslist in my area years ago that was doing this to stock cams and selling them as aftermarket

Agree with the others. There is no cost effective way to repair the cam lobe (or the lifter if he was thinking about repairing that also).
Also a good time to evaluate the cam he had and whether it was everything he wanted. If not, might as well consider a new cam profile, too.
