  • Tool marks

    Rooster posted this photo on a different thread the other day and something caught my eye by the cover dowel.



    I recognized the marks right away because my sand cast gear cover for my 51 has similar marks, though in a slightly different location.



    If I had never seen the photo Rooster posted I would've continued to assume these marks were from some one having the cover clamped in their bench vise for some type of repair and would have blended them out. Now I will not only leave them, but do whatever I can to preserve them. It's amazing what you can learn from one photo. So I was wondering how many others have seen similar marks on parts? I guess they were left by the clamps at the milling machine when the screw holes were counter sunk. I wouldn't have thought something like this would pass quality control, Guess I was wrong.

    That's very interesting, bmh. Good eye. And for the record, I need to report that the photos I posted are copies of 1952 factory photos that I got from Chris Haynes. I cannot take credit for the photos, rather we can thank Chris!

      That is super interesting Brian! I just had to run out to the shop and check out a cover I had hanging on the wall. But, alas I had forgotten that somewhere in it's lifespan somebody decided to start a modification! Any theories behind why someone would start grinding like that? Besides the obvious I guess, maybe they wanted the smoother version? Sorry to sidetrack the original point to this thread.....

        That looks like it has been whacked, really hard or multiple times with a hammer. ...bill

          A similar fixture mark can be found on a great many muffler body clamps, and can show up on just about anything.

                  People fall down on them.
                  It happened a lot, and still does.

                    Cotton, you make things so damn obvious! After you said it, I thought to myself....."why didn't I think of that"? Now that cover has a story!

                      Returning to the original point of this thread, I found that same tool mark on my cam cover, skid plate, and the the foot shift support bracket when recently tearing down my 65 FLH.

                      Having seen Rooster's original post and the related comments of others there and here, I took those marks as evidence the parts in question were factory originals. Now I'd be glad to find more as I clean things up and reassemble!

                        That cover couldn't be run with that hole in the oil passage.

                          Sure it could. Just not for very far.

                            Chris........I guess that's why I paid five bucks for it at a meet a few years back. It's art for now but could be repaired and put back into service one day.....
