ADade Posted November 30, 2018 Share Posted November 30, 2018 I'm very close to getting my 1918 34 roadster running, but just found that one of the rockers is broken (see pictures). I could glue the part together and use it as a pattern to get a new one forged, but it would be much easier if I could find one. Anybody have suggestions?

Morgan Wright Posted December 1, 2018 Share Posted December 1, 2018 They can be welded. I have one rocker on my car that was welded long ago, and it's fine. Link to comment Share on other sites More sharing options...
Brian_Heil Posted December 1, 2018 Share Posted December 1, 2018 Thought Dean Tryon had a number of these re-cast? Link to comment Share on other sites More sharing options...

Hubert_25-25 Posted December 1, 2018 Share Posted December 1, 2018 I would have it recast, or even consider milling it out of a billet. Some of these old steel castings are pretty questionable. Link to comment Share on other sites More sharing options...
Morgan Wright Posted December 1, 2018 Share Posted December 1, 2018 What's the reason for not welding it? Link to comment Share on other sites More sharing options...
Spinneyhill Posted December 1, 2018 Share Posted December 1, 2018 Might it be a porous casting, heavily oil impregnated, making it hard to weld unless the oil is removed? Link to comment Share on other sites More sharing options...
Hubert_25-25 Posted December 1, 2018 Share Posted December 1, 2018 Cast iron or cast steel makes a difference. It would likely need to go in a furnace prior to welding as part of the process. Certainly a specialist job. Link to comment Share on other sites More sharing options...
ADade Posted December 1, 2018 Author Share Posted December 1, 2018 Our research indicates it's cast steel. We're contemplating drilling up from the bottom, tapping and putting in a plug to hold the two pieces together if we can't find an unbroken one.

CTCV Posted December 2, 2018 Share Posted December 2, 2018 This may sound a bit foolish but going to offer it up anyway. If you can find a piston rod that accepts the same diameter pin you just need to make the base plate out of steel and that may weld better. 1 Link to comment Share on other sites More sharing options...
DonMicheletti Posted December 2, 2018 Share Posted December 2, 2018 Since it is steel, it should weld OK. Link to comment Share on other sites More sharing options...
ADade Posted December 2, 2018 Author Share Posted December 2, 2018 Thanks everybody for the thoughts and suggestions. I found one, thanks to Larry Schramm in Detroit. 5 Link to comment Share on other sites More sharing options...
Morgan Wright Posted December 3, 2018 Share Posted December 3, 2018 I wasn't fooling when I said to weld it. This 80 year old weld job is stronger than new. They knew what they were doing 80 years ago: Link to comment Share on other sites More sharing options...

Got it welded today. Maybe Alex will post a picture of the weld job. Link to comment Share on other sites More sharing options...
tblack Posted December 8, 2018 Share Posted December 8, 2018 I have several welded as well, seem to be fine....I had a number of extra 4 cylinder ones that went with a truck load of 4 cylinder parts to John Henry over in Mass. I dont have his contact info but maybe someone does....Included in that batch was a rebuilt 1918 4 cylinder engine (Babbit, pistins, the works)...so it might be worth looking him up.
