its not easy to do brokenbiker but i have done it myself with the smaller bottles I also did it with the bar in the middle as well
that top is made from one and the centre joint is visible
i found the best way of doing it was to use a steel gate post and also a solid part at back about an 1" away for it bending it by brute force at every 1" to 2" i gave up on the sledge hammer job as too noisy for neighbours
i also found out you cannot get it truly straight but i got it good enough
even the door is made out of the same bottle

i will be cutting exactly the same amount as if i had flat steel anyway...and i have to go out and get cutting discs even if i buy flat steel...i cant see how im going to spend more on these things when neither are involved in the flattening...
once i have got some discs i will be cutting the basic shape out, flattening each piece and then welding a few joints up. if i had flat steel to begin with i would still have to cut the pieces out of the sheet, i would just save a bit of time by not having to hammer it flat...time is not an issue as this a project that i want purely because i want to make it
also, what sort of price does a 2Mx1M sheet of 3mm go for?

All this sounds positively dangerous to me, a not very flat surface, a potentially dangerously mounted jigsaw with difficult to operate trigger and a blade that's gonna be bouncing around like a mad man.
What intricate shape do you really need to cut that cant be done with the jigsaw operated in a conventional fashion ?

i cant see the point in spending 46 quid when i already have the same amount of steel sat in the garden doing nothing...all it is going to take is a bit of hard work to get it flat enough to use...
my mistake was trying to flatten it before cutting the bits out that i need...it is going to be far easier to flatten it if i am only dealing with 250x250 chunks at a time and then a bigger bit later on for a different project

im using 2...i have 4 sections that are 700x670mm (when flat) which is 0.469sqM, so all together i have 1.87sqM and will most likely use the majority of it in these 2 projects

The only way you will do it is to batter hell out of it with a sledge hammer. It will look like it's been in a train crash.
When you start on it, maybe your neighbours will club together and buy you a flat sheet.
We give bits of stuff like that away for nowt - not a local fabricator you can have a rummage round their skips?

neighbours arent in during the day and they have never complained about noise before now and im not the only one in this street that makes that much noise.The only way you will do it is to batter hell out of it with a sledge hammer. It will look like it's been in a train crash.

i dont know of ny local fab shops around here except the ones that we deal with in work and they are that tight they squeak when they walk, have tried getting off cuts off them before and they tried to charge me the going rate by weight plus vat so i bought new steel instead as it was easier to start from a big sheet than off cuts and cost the same

You've got more chance of platting fog than flattening a gas bottle with the tools you've got. As has already been said as well it is next to impossible to use a jigsaw upside down, you're not accounting for the weight of the machine and you pressing down stopping it from bouncing around everywhere, I am speaking from experience, test it by holding it in a vice. Check my posts I never spend money unless I have to and I'm all in favour of upcycling or modifying tools if it can be done safely but you really ought to rethink this project you'll save energy, money and time .

Just to add to the complexity of this.
Why does the jigsaw/finger remover need to be fixed to a metal base? why not invert it and fix to a wooden base?

because i have metal and dont have wood is pretty much the only reasoning behind it

same idea seems to work well for these guys...even the one that is just slotted into a bit of wood and clamped overhanging the bench...
mind is going to be screwed into the bench i am using and the jigsaw is going to bolted to the frame using the original bolt holes for the parallel guide and 2 holes that i will be drilling in the base plate to put bolt and nyloc nut on for now until i devise a quick release mount for it if i find the nut and bolt too tedious

Not withstanding the dangers and impracticality of what your trying to make - believe me I've made some death invoking contraptions that seem like a good idea at the time :-)
cut the pieces to size and stick them on a disposable barbecue, cut a few small holes in one end of the tray and light up as normal. Once its up to temp use the wife / girlfriends hair drier to improvise a blast furnace. Direct the (cold) air into the holes from a distance otherwise you need to budget for replacing said hair drier.
I've got 6mm plate cherry red on one like this, although I did make a tray, air duct and use a small snail blower... but a disposable barbecue is fine for one off jobs..

thats a fair idea...i have been keeping hold of an old hair dryer for when i eventually decide to make a forge...i havent got a disposable BBq but i have got charcoal and a (now redundant) fire pit made from the top of one of these gas bottles...wont take much to cut a hole and hold the hair dryer in place while its cooking...there is enough space in there for the bits i need too...could also harden the knife i started making then stopped because i had no way of hardening it myself
