Re: Broaching
"who has been working with these since him and Moses graduated high school....
" Thanks a lot Bob.....  I have (lets say more than 2) original blocks which were purchased loooooooooong before 409 cars were being "built" in the hobby. They all have the arched (circular) grinding patterns on the decks, front to back, both banks. I have had technical discussions with both Art and John, and I respect their knowledge and experience VERY much. They are both gentlemen and I believe very probably among the most valuable great assets for correct historical reference we have within our collective hobbies................however I will say that if you are the bottom line authority on apples, that doesn't make you qualified to document oranges. I like oranges.  Verne

Re: Broaching
I am not an expert on locks by any strech of the imagination, however I have spent 30 years or more
Machining all kinds of materials with Planers and milling machine, shapers and surface grinders ect. Bobs explantion in his previous post is right about the Planer. However this bock has been machined with a carbide fly cutter either by the factory or by someone else.A fly cutter is a round tool with one or more carbide inserts and can range form 2 inch diameter to 12 inch diameter depending on the area to cut with multiple carbide cutters .There is no doubt about it. It cant be a blanchard grinder because thats what is used to grind your flywheel.If the bock had a blemish after it was planed and before it was stamped then the factory would put it aside and machine them with a fly cutter later on together with other blemished bocks. If the block then cleaned up and was within the tolerance then it would then continued to be assembled and then stamped hope that helps suprss70
