Cutting holes in X member? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

shortbed70 · 02-17-2009, 09:49 PM

I am going to be installing some rings in the rear x member for exhaust to go through BUT I don't have a plasma,oxy torch. Is there another way? I know I could use a hole saw but I would have to find a way to center it any other ideas.

Hole saw through a 2 x 4 the size you want then screw or clamp it to the crossmember. This will keep the hole saw steady when you go through the crossmember without having to have a pilot hole in the center.

Do your hole saws not have a pilot bit to keep them centered?

Good idea on the use of wood as your 'pilot' hole.

The c.member isn't solid where the pilot bit would need to be centered. Some guys weld a piece of strap across the c.member & drill a hole in that as their pilot hole (& keep things consistent).

i used an air body saw for mine. it took a little time but was worth it since there was zero cleanup after and no heat involved.

This works well when you already have a hole and want to hole saw it larger.

Great idea. On smaller holes, I have always used a wood rod as a filler. I guess it helps that I alwys have a surplus of broken pool sticks available.
