  • Bounce Board dilemma

    Got a busted RR BB to replace. The bolt heads are smooth with the "I don't know what that is" underneath. Anybody seen this before? Looks like the hand grinder will come out.

    Never seen those in my life... but Yeah I'm with your second choice, I'd be pulling out the trusty 110mm Makita Grinder and cutting those suckers off....
    AS REQUESTED....The all new and VERY improved "super cool" Pin_Head with super hip shades.....

        The are off of real old 70's or 30's - I have seen them in a couple places I have been

        Take out the right angle grinder and cut off the back side

          That's the thing, there is no drive and the crude is cleaned out. You are looking at the shiny smooth heads.

              Must have run the nuts on the back with some tool. As said before lop them off with your grinder. I tried using carriage bolts with Bowl Tuff plastic bounce plates (Dave made special) so that you would'nt have to counter sink the bolts and lesson the thickness of the plate.

                There is no nut - and there was no nut

                The early machine had rivets - and they are good rivets as I recall - the body on them are hard and can be tough to get off

                  So they were designed not to be repaired. (easily) ?

                      Good rivets to say the least. The serial #'s on the 70s are in the 99,000 range and if I'm guessing right, that puts the age of the machines 45+ years old. If this is an original part, wow! None of the rivets are loose.

                        Wow. Brings back memories. Didn't have the use of a hand grinder so had to punch back out each rivet with a punch and hammer. After 20 lanes of this, my arms were in pretty good shape, but never ever want to go through that again.
