I just started re-doing the rear section of my rigid frame (needs to be a little wider), At the moment I'm using 3/4 scd 40 pipe to do the mock up and figure out how i want it then I'm going to transfer to some DOM. I have some 1 inch .105 wall Dom I picked up from work, thoughts on if this would be good enough to build the hardtail out of?

I'm not an engineer, but, I always used .120 wall when using 1" tubing. If I was using 1.125 or 1.5 inch tubing, I would feel more comfortable with the thinner wall tubing...

yeah that's what i was thinking as well. but just curious if anyone had used it. .120 DOM in my area runs $135 for 17 to 24 feet, I have no idea why the length varies so much. no one stocks it and has to be special ordered, closest supplier who stocks it is about 3 hours away. I have enough of the .105 to do what i need, but i can always make some bars or something not as structural out of it.

Dang I hate to tell you what I paid for a 24' section. If you did some cross bracing from the chain stays to the seat stays you would probably be okay using a thinner wall but that's a different look (think ladder bar syle). You could use non DOM tubing if its cold rolled, I've done that before or chromoly but if DOM is hard to get then Chromoly is probably the price of unubtanium! Good luck man, I hope you can find something that works well for you!

no one stocks any kind of tube around here, all i can get even close to 1" tube without special order is 3/4 pipe.
when i get done with the pipe i'm using for mock up I have a 10hp briggs i'm gonna build a minibike or mini trike outta. so it's not a total loss.

I'm gonna do some research, if the DOM is A LOT cheaper it would be worth the drive and pick up several stick. I have a few buddies who would like to have some as well.

Yeah I paid $62 shipped for a 24'. I live in Chicago and bought it from a supplier outside the city if that gives you any kind of perspective. The place I buy from sells by the pound as long as it's in stock too so maybe check if thats the case and they charge to cut it so if the long length is an issue save some cash and bring a grinder with some cut off wheel and do it yourself.

less then half price would be worth the gas and time to make the trip.

I cut out the upper wishbone. the tube measures .140 and looks like it maybe a double wall? (tube inside a tube) kinda hard to tell.

speedymetals .com 1 1/8" .120 " wall . 4 sections of 4' tubing for around $100 shipped last I check. I'de never use 3/4" shc anything or black pipe shit. 1" .10 wall maybe a lil wobbly feeling.

I'm not using 3/4 pipe for anything other than mock up. that way i don't waste the expensive shit.

Definitely go with .120. I bought a 10' stick of it yesterday for well under $30. Go with an online company is you can't get it anywhere near you.

Also, I prefer .120 for handlebars too. They may not be structural, but you're just as fucked if they break.

you can also use erw tubing if budget is on your mind. just go up a thickness to like .125....i think even that .120 will work fine. its generally cheaper. it does show a weld seam though but that covers up with paint.
