I am trying to finish details of previous wood frame and sheet metal, My question that I have, searches have not helped, around the top back there are many nail holes in the metal about 2 1/2" apart, is this to nail the sheet metal or are some of them for attaching the top? Or does the top only attach to the wood frame above? I don't want to put nails in all these holes cause' they would be a devil to get back out if need be.
I'm not an expert on how it was done originally, but on my 1924 cut-off touring (now a pickup), I put a nail in every hole to attach the sheet metal to the wood. I attached my seatback upholstery and the top to just the wood that was above the top of the sheet metal.
Depending on what kind of wood you used and how solid it is, you might consider pre-drilling a small pilot hole for each nail.
Hope this helps.
Thanks' Mark, but the new wood was done by the former owner (owners?)and the sheet metal is original and in good shape with original holes, much of the metal has not been nailed, like around the quarter windows, I have to go over all of this the next few days, I can drive the proper sheet metals in the wood ok.
I have a 24 Coupe and as I remember there are nails that are used to attach the sheet metal and tacks to attach the top material.
If the previous owner of your Coupe installed new wood in the top area and didn't finish nailing the sheet metal you can carefully use a small drill bit to predrill the holes.
I did that on mine when I replaced some of the top wood.
When using tacks to nail on the top material I wound up using small needle nose pliers to hold the tack in place to get it started. Made things much easier and kept from bending the tacks.
I used a really small drill bit to pre-drill all the wood through the original sheet metal holes when assembling my '15 runabout. Broke I think four bits before it was done. Even though I was very careful with the drill and ran it very straight. Hard wood, bits just twisted off. I also used ringed nails for most of it so they will be less likely to back out.
On the coupe, I can't help with a lot of inner details because my coupe is one of the few cars I have ever bought already done.
Thanks to all you guys, The few nails I have put in do not drive easy without predrilling the wood, but ok, no bent nails yet Just to mention broken drills, several years ago I did a '31 A coupe, and one quarter window trim would not go in place like I wanted, with a better lighting I could see a broken drill bit in the wood
