Welding over RHINO LININGS

[tommckenna6]

I am replacing an aftermarket roll bar installed in my 65' FJ40. The new roll bar needs to be welded on but the whole inside is Rhino lined! Is it possible to strip off the Rhino and weld it metal to metal?

Anyone ever done this before?

Yes. Outline the area you need to remove plus enough room for your weld. Then take a razor knife and cut the outlined area. I used a wood chisel at a very low horizontal angle and scraped it away. It is a bitch to do..

a 3" wheel grinder will take if off but it is messy. You will get a nasty buring rubber smell and the liner will get gooey but it will come off.

wear gloves if you do the above one, the burning rubber stings and sticks! :LOL:

Are you going to weld the roll bar to the body?

Why not bolt

After looking it over I think you are all right...bolt is the way to go.

Not trying to insult you - but have you done any research yet into how to spread the load correctly for a roll bar when attaching it?

You need to distribute the load in case you really do go over, otherwise the bar will punch through the sheet metal & possibly (probably) cause injury to occupants of said rig going over.

At a bare minimum you need to weld plates parallel to the floorpan to the bottom of the bar ends, then use a backer plate of decent size & thickness (I like 1/4" for both sides) as a large washer for your bolting surface on the other side of the body (underside).

Also, these are critical welds, not the place to do your first bead. If you have a welder buddy, buy him a few frosties after he does the work for you. Pay for it otherwise, it's really that important.

If you look around you'll see what I'm saying.

First of all, he posted the question in the first place, second, you are right. A roll bar is a safety net. it is your last chance of survival. you don't see people making seat belts out of twine. You gave him good advice about backing the mount and trying to get the rollover weight to the strong frame. I wouldn't worry about insulting him, you are trying to save his life some day.
