Going to have a bash at this..!!

[Andy_B]

Just aquired a 3ft sheet of 5mm top quality steel plate for nowt...so i am going to have a go at hacking out the diff plates...thinking a box of slitting discs some grinding discs ...oh eye and face mask !! anybody attempted this ?

[whitstella]

just how i did mine but also used a jigsaw and 10 blades to cut out the holes.

Very doable if you don't mind spending the time on them & as the material came free it would be rude not too

I used a gas axe on mine, not as crue as it sounds when you know how to use one

Got gas axe at work but i struggle to get a clean cut with it ...seem to always end up with it looking fine from the top but the bottom side is all snotters hanging down....we do have a plasma but some a/hole buggered it up and its an un economical repair...

What type of nozzle are you using? as there are specific nozzles for thinner sheet that make life a lot easier.

Whatever is on it when i pick it up !! my trade is instumentation and electrical ...so the mechanical guys kinda hide all the stuff i need and the know how too !! but i do callouts and nightshifts so can rake around and teach myself when they are not about ....seem to remember seeing different number nozzles in the store...is there a specific for 5mm ?

If it's Oxy/Accet

1/16" cutting nozel
10 Psi Accet / 28 Psi Oxy ( Approx )

On 5mm plate you'll need quite a fast speed of travel when you are cutting .... Too slow & you'll get a build up of dross just as you describe

It is very important that the cutting nozel is clean, especialy the centre Oxy hole.

When you have marked the part to be cut out, it will help if you use a centre punch to mark the lines ( Every 10mm or so & closer on the curved parts )

Once you get the knack of cutting a reasonable line, it does not take long to fettle the part with a flap disc

I am pretty sure I have a spare set of plates in 6mm already cnc plasma cut.

They mad need a buzz over with a angry grinder, just to take the suface rust off, and the holes might (unlikely) need a drill running through to make them perfect but they are yours for a few beer tokens.

I think I also have to front wishbone plates again 6mm plate but with extra few cut outs probably lighter than the 5mm ones lol
