Practice Welds and Table Protection?

The stainless will be screwed down to the ply. That's the idea anyway...

So your'll be using countersunk screws then,if so you'll need to screw a hell of a lot into the ply (a lot of drilling), if the ply isn't also screwed/fixed to a really solid flat surface you will end up with bumps/bows hence not truly flat,pita esp when you need to set out a bit of frame work.
I did this to a little outside work bench using mild steel 500x500x3mm drilled in 100mm squares including the edges not with ply though i used kitchen worktop 45mm thickness,was nice a flat for a while but over the years it isn't now,mind you,in all that time its had engines,back axles, BFH blows,loads of heat,kicked and punched etc etc

Questions, how are you all fixing your sheet of steel/SS to the worktop/ply/wood whatever,screwed,nailed,or glued,and how are you keeping it as flat as possible?

Mine isn't fastened at all - I scored the edges then battered it round and underneath the worktop, then welded up the seams - project in glorious technicolor(tm)

Yer i know skoti seen that,has it stayed flat still?
You like me also used a thicker base, dont think even 25mm ply would do the job.
By the way,end of that vid says more to come,wheres part two then

If you want something flat get your hands on some kitchen worktop
It's also a bit more heat resistant - not totally just better

Yep - stayed flat. The edges are a little rounded but the 99% surface area hasn't moved.

Here's part two
And the outtake

Cool well done,not happy with lack of swearing on the out take though,thank god they put a the guard on the bottle
