Frame ramps for 379

Who says you can't drill the frame?

Drilling the web (vertical portion) is perfectly fine. Drilling the flanges is a huge no-no.

 

As he said above, perfectly fine to drill the frame.
It can be welded as well if dine by a competent person.
Especially way on the back of the frame where your ramps would go. What's the worst that would happen? Back of the frame falls off. Not gonna happen anyway

 

I just added some ramps to my frame . now they arent the greatest but they get the job done for what it is.

I used 3/16 bit to 1/2 inch to 3/4.. Slow and steady wins the race. You want brand new sharp bits. And drill nice and slow. Going fast is only going to burn up ur bits. Its a all day job if by urself. It took about 6 hours total. To drill the ramp holes into the ramps and then drill the frame out.

3/4 inch grade 8 bolts with 3/4 inch grade 8 flange lock nuts

 

I would find a good tool rental store and rent a magnetic drill it's well.worth the rental if you value you time at all

 

Mag drill with an annular cutting bit. Take longer to set up each hole than to drill it.

 

Doing it by hand builds character

 

I did the entire frame from my cab back by hand.

 

This is me using my then new Hougen mag drill to drill holes in a truck frame. I had a template as you can see, and some may complain about not using the safety chain etc., but as long as you get a good solid hold with the magnet, it works fine.

 

I regularly drill 1" holes in 1.5" thick steel plate with one of those. Takes like 3-4 minutes.
