Thread: Welding to a Chassis

I strongly suggest bolting them onto a plate that youve welded to the chassis as opposed to welding the frame directly to the chassis.


Ive seen the spikes that turn up while welding on a chassis on a crow while down at ALTC. While I dont think that its likely to cook off any of the simple electronics in a D1 it certainly cant hurt to take the precautions mentioned above.

dont forget, pics of the work,

My thoughts of bolting it to the chassis was my first thought but to create the same strenght as a weld i would have to do 4 bolts ,, and drill through both sides of the box section of the chassis or would the pop ins be enough
cheers kelvin

youd have to drill through and insert spacers to prevent the chassis from crushing.

I was talking more about extending the chassis by welding a plate that extends past the chassis and bolting into the extended plate.

ah yeah good idea

cheers kelvin

well i finished my rear rocksliders yesterday it took me about 3hrs using scaffold tube and some checker plate that was lying around all in all it cost me nothing , the 3hrs that it took me ,i was at work getting paid anyway so i actually got paid to do it LOL

i used my newly obtained surge protection jumper leads disconected the battery and isolated the alternator

i welded a 5mm Z bar plate to the chassis doing 2cm welds every 2cm then cut away my body and half of the steel rear bar ,cut a slot into the scaffold tube where it would slott up into the rear bumper ,then spot welded that and then welded the scaff tube to the chassis it turned out pritty good and strong i will see how it goes this xmas wheeling as i might change the one side to allow bigger wheels in the future , the other side i thought of that before i welded it on dam it not planning properly oh well it will give me something to do at work the first week back LOL

Regardless whether you weld direct to the chassis or weld on a mounting pad, dont forget to treat the inner chassis. On our RRC I have drilled a hole (20mm approx) directly opposite to any chassis welding so you can paint or treat the area as the inner chassis will be heat affected. This also depends on how long you want to keep your car or chassis. We also waxoil ours as well to extend its life. 85 model and rust free

Everyone forgets that chassis can rust from the inside out.

I forgot about the inside of mine
I better get to it, thanks for the heads up Justin
