Re: My 1970 GMC “Project Splice”
I'm scratching my head trying to figure out the best/easiest way you can make holes in those brackets to make it lighter. If it was lighter gauge, I'd say to rent a knockout set used for making electrical knockouts. I have one on my van made by Southwire. I have the dies to make up to a 4" hole. It works really slick, but I just looked up the specs on it and it maxes out on 10 gauge steel. Other companies make them too, maybe theirs cuts through heavier stuff. You might just have to go buy a couple really nice hole saws and cutting oil. Also buy extra pilot bits. You will probably break a few going through that thick of steel. Or use a carbide one shot hole saw, but that won't make as nice of a hole as a Diablo hole saw or good brand named one.
Maybe you have other ideas on how to make the brackets lighter or making going to a completely different design than circular holes. Just throwing out a suggestion or two.
