Default 2mm thick steel cutting?

Hi guys,
Am I right in thinking I need to use a thin grinder disc to cut this or could I use a jigsaw?
Thought i'd ask before I make an almighty balls up!!

Cheers
Russ

I used 1mm thick slitting discs (very thin grinding discs) they slice through 3mm thick steel like a knife through butter. I have used 5 discs to cut out all of my chassis plates and do a lot of other jobs.

May i ask what you are using the 2mm steel for?

Will it be too heavy or can i get away with it? It's cost me nothing and i thought they aren't massive bits so wouldn't make too much difference?

It,ll be fine for your floor, admittedly its heavier than an ali floor but if you don,t cover in the prop area that,ll save a bit of weight

It was free....use it

ps... don,t do full welds all in one go, stagger the welding, to avoid heat distortion.

cheers
andy

extra info....Spuds Roadster has a steel floor, doesn,t slow that car down.

I'm told that welding on a steel floor can lead to corrosion problems, and I believe it's actually not allowed in locost racing because of this. I understand the corrosion is caused by there being 2 pieces of metal close to each other that you can't get at to apply rust preventative, and that the thin gap causes moisture to be drawn into it.

Jigsaw cuts it fine and cleaner and easier to control .

Dont quote me as I have not verified it but I am fairly sure the MSA blue book requires a steel floor for racing.

You could well be right, but I have a feeling, I'm sure I read it somewhere, that such floor had to be rivetted on rather than welded. Obviously the rivetting would then allow sealer to be applied to the joint, thus preventing the rust problem
