The gen bolt holes on my Eldo project are completelu gone...Trashed. I
want to build them up(somehow) and retap the holes or mount threaded
studs in there.
What would be a good material for filling these former holes???
Thanks!!!

Hey man, Yeah, she's probably forgotten me by now, sitting there in the corner, collecting dust. Did all that already, the dowel is a good fit, I will take another look at it though, If it's at all shot I will take you up on the dowel. I did fill the whole area where the bracket sits, came out pretty damn good. Like I said, I was gonna go with helicoil, decided to try the time-serts,I was thinking that the gen. mount studs could be bolted into something harder than aluminum, granted the helicoil would give extra ummph but the time-sert seemed as though it would disperse the load even more seeing as how the OD is a bit bigger. we'll find out seeing as though the holes for the timesert are already drilled. I just need to know a depth. I stopped at .420". I would go a bit deeper if I could, just not sure if that's a oil channel or just webbing running along the top of the engine. Did you, have you gone to the shop breakfast? Chris told me about it but, I work very late 3-4am on Fri & Sat nights, so I might be hard pressed to get there.

The fellow who owns that yellow 1974 Ducati 750 is a pretty swell lawyer/biker . He may be able to refer you . As for the generator base : there are a number of items that all contribute to sucess . The little locator dowel must FIT tightly into the hole in the case and securely into the threads in the generator . I make up oversize locators and ream the hole for a good fit . The waffled area the bracket sits upon lacks sufficient area to support the load . I like to fill the area with metal filled Devcon or similar . Use STUDS so you can get full thread engagement . Use a large ,hard steel plate between the bracket and nuts to spread the clamping force . Also of coarse avoid fine threads in the soft material . The Timeserts are a bit large on the OD and Helicoils allow thicker walls to remain abit of a trade off . Also the Helicoils give more flexibility in length . You can call me if you want come over and use the lathe etc. I'll be glad to give you a hand out here in Utica . Kevin Graf wrote:
