It's not a Flintstones bicycle!

Stone cutting discs won’t work! You want carbide or diamond 2mm discs and a fast angle grinder.
Snap a chalk line and follow that if you have a steady hand. Or clamp a length of angle iron to the tube as a fence.
Decent flapper wheel to finish, and then throw it all on the scrap pile and wonder why you bothered.
Photos please or it never happened

If I was attempting that, I'd use a mini grinder with a 1.2mm cutting disc. Note, there are 2 sizes available, in the UK the common size is 115mm OD with 22mm bore, over here the common size is 105mm OD, 16mm bore. They are referred to as 4.5" grinders or 4" respectively. The UK size has the advantage I think, a little bit more depth for your money.
As mentioned already, where the tubes meet might be troublesome, daresay I'd think of something on the fly, but in cold blood I can't say what I'd do really. Good luck, and a few pics please - else it was all just a dream

If you have a compressor this would work https://www.toolstation.com/air-cut-off-tool/p81639

He's making a true fat bike, not only fat tyres, but fat frame, although how he's going to get a crank long enough is still puzzling me

Too much wobble with a slitting disc IMHO if he wants a straight line. I’ve regularly cut stainless pipe for timber winch cable ferrules with 2mm diamond discs and a Makita 18v cordless. The OP can do what he chooses. The question you should ask is why is he botheringI have already posted a link to a 0.8mm cutting disc. Not sure why people are suggesting 2mm ones

I tend to use 1mm blades only as they are more easily available

Wow, never knew they made them that thin. Not seen any over here, just as well as they sound like an accident waiting to happen. The 1.2mm ones feel flexy and fragile enough.I have already posted a link to a 0.8mm cutting disc. Not sure why people are suggesting 2mm ones

When I first started I loaded up with as much personal protection as I could find, but honestly no problems and would be happy to carry on using them.

I worked for my former father in law making wrought iron gates and railings, and other stuff. He treated the grinder with disdain, having seen a colleague peppered with shards. He would reach for a file or the saw first From what I learned, pay What you can afford for best discs, match the rpm to the motor, and make sure they are dry and in date. Oh, and keep the guard on! Many supposed Safety glasses are also not rated for flying abrasive disc.
