Can anyone tell me or provide a diagram with measurements of all necessary nut plates that need to be welded in before i go and box my frame (1929 Model A Convertible)!!! A little vaque but please bare with me! New to the Model A World (Newbie)
Wouldn't that depend on which engine and which transmission you are going to use, not to mention the type of shocks, electric fuel pump, and other components used?
In addition to the above factors plan on drilling and tapping for fuel line clips, hydraulic line clips, electrical wiring clips, E-brake tabs and vacuum and oil cooler lines. Put the holes as near to the neutral axis - the centerline of the boxing plate - as possible. It is infinitely easier to do those holes on the plates, perhaps on a drill press, than laying on your back to do it during ***embly.
First of all you call your car a "1929 Model A Convertible. In '29, open car's had Roadsters, Cabriolet's and Phaetons, which body style do you mean? If you can find the instructions for the wood body mount blocks that fit your car they will tell you which holes are used to mount the body.
I will try to have better info for everyone on the next trip around this discussion but i do appreciate the replies. Gives me more to think about!
You could just weld a thick strap of metal underneath the frame rail in the general area of where you think the holes will be, then drill and tap the holes through both the rails and the thick metal plate. Then you won't have to worry about getting it in exactly the right spot.
We have built and repaired a whole bunch of race cars over the years and never had the need to thread a screw into a frame member. Boxing a stock A frame will help make a street machine handle better but if this is a race car of any kind, it will require a whole lot of additional bracing.
I’ve used many nutserts style using a pop rivet looking tool and put them where needed. I file 3-4 notches in the hole and use red thread locker on the lip. With an Adell style clip you will never see one.
I was talking to my father (80yo) about my roadster and he corrected me by telling me that its a convertible because of the windshield frame. Thats why i called it a convertible, because i thought he new better.
