DSM8 360 Posted February 14, 2022 @Bubbagums somehow connected with me in some thread somewhere on this forum with the comment my subframe is cracked. Told him bring it on by, they all do that but I can take a look and see if we can do something about it. He and I have different ideas of cracked, and partially nuked. 😂 I am using links due to the size of the pictures Before pics BigOl Piece missing thar Dirty greasy ugly ol girl One more I cant believe it's not butter, given how it looks before the prom shot So what is very interesting was the fact the extrusion that makes up the frame is X shaped internally so I could not create new billet slugs without a WHOLE bunch of work on the mill. And the inserts that were there could not tell if they were a casting or billet but the whole thing was an absolute horror to weld. I spent more time cooking out the contaminants than actual welding time. But after about 3.5 hours we got er done After Pics Not sure which side but they were both pretty bad off. Had to redrill and chamfer the holes Managed to get it all ground back to square, it's about 1/64" off on the inside but since no way to get it on the mill I have to face it off will have to due. And of course the warrant expired at the end of the concrete slab of the workshop. Bob you will have to give us an update I will be VERY curious to see how that holds up given how much damage existed before the repair. Might want to keep an eye out for a new subframe just to be safe 😉😉 1 Share this post Link to post Share on other sites

Wierdrider 187 Posted February 16, 2022 Awesome job Dave👍 Could you see a good way to reinforce the subframe to support more weight? Share this post Link to post Share on other sites
DSM8 360 Posted February 16, 2022 It was never designed for weight there is just no real infrastructure to add to if I Did it would be rebuilt using dom tubing Share this post Link to post Share on other sites

It will be interesting to see how this holds up under use, in the meantime I hope he is shopping for another subframe because this one can not be repaired again. Too much contamination where it was damaged to truly get a good and solid rebuild, I suspect it is going to crack, just no idea when or how. Share this post Link to post Share on other sites
DSM8 360 Posted February 16, 2022 @Suspenders George thought you might like to see how the repair went since you were there for the initial unveiling. 😁 Share this post Link to post Share on other sites
