    Hey Guys,

    I'm more kind of a silent reader, collecting ideas, asking silly questions and learning.
    but now I got something that might be interesting for you so i wanna give a little bit back to the community
    some time ago i bought an old dog bone intake here on the hamb. No bone on it just a cap.
    being curious i wanted to look under it and then stuff fell apart. Badly helicoiled as it was it wasn't possible to screw it back together.
    ok so let's fix that thing as they are no so often found. Bored out the helis, parts broke of,a mess bigger than expected
    welded some aluminum into it and filed it down by hand, taking care of keeping it level to the carbs mounting surface cause if i find a bone i wanna use it.
    this is when i took the first photo

    drilled out the rest of a helicoil from the cap.
    Finally not that bad... Maybe will blast it and bolts need some patina :)

  8. Nice save! I'm not familiar with that intake. What is the "bone" of which you speak?

    I think in this case it was a wishbone - as in he wishes he hadn't bought it. :rolleyes:

    kinda wish i had one ;), but they are available, its the heat spreader for the exhaust gases which bolts on top of it and goes even under the carbs. There are other threads with picshere on the hamb

    Jan, Definitely worth picking up a dogbone from Mike Herman at H&H

    ok, got some more progress onmy favorite intake.
    Someone, whysoever, cut up the gen-mount so i tried to rebuild it. Made some filler pieces, but they really welded up crappy[​IMG]

    Nice work, I am surprise that you did not just buy an NOS one from Sears. Only joking, good job.

  18. They look like prick punch marks, probably used to keep the gasket in place.

    Wow! Really awesome work there! Love to see the talent on here- especially to save something that most would consider un-savable.
