I am restoring a 70 k5 blazer and I’ve come across a part that I need. Believe it or not no one reproduces or sells this part. Originally it was made out of plastic but I might try to make it out of aluminum.
I’ve only been working in 2d so far with my SO3.
Any suggestions on how to make this:
Right now I’m thinking I will need a flip jig - I would appreciate any advice you can share that will help me make these efficiently.
A flip jig should work if you position the cylinder feature vertically. You’d need a cutter with a flute long enough to get to the underside of that dome, though.
Two other possibilities would be:
-Make it in two parts out of plastic and then bond them together (cylinder + “dome”)
-Machine a two part mold and cast or injection mold it
I like all the 67-72 Chevy trucks too but my hands down favorite is the k5 blazers. Full convertible truck with a back seat - hard not to like. Hope mine will look kinda like this 1 day.
This is the area that got me thinking that milling it as two parts would be the way to go:
You’d need a seriously small cutter to minimize that interior radius. That goes for pretty much any angle you cut it from, as far as I can tell from the provided photo.
I would prototype a few out of alumunim. If there was a big enough demand, an online place like Emachineshop can make the mold from your part file and take care of the injection molding as well.
