The Chopper Compendium

Hello , I am wondering about useing 2" solid round hot rolled mild steel from a local steel crop outlet for neck material.the guy had no idea about specs for this ,my book I got says it should be a36 or 1020 i dont know how to tell the difference. Or should i just get a piece of cold rolled.?.

Good to see you hear dirtbag!

You got to throw some pics up of your build to get these guys mouth watering!

I used my stock neck so not sure but I would think cold rolled????

I would think hot rolled would work its just more work with all the cleaning to weld it most regular cheap hot rolled is 1018-1020 anyway and I would think when you bore it out it will be around 3/8 thick for the cups and by the time its all braced in it should be fine

I googled it and this came up..a familiar name....

"" 2” 1026 carbon steel DOM tubing;""

Thank guys...yes I looked at his page that is his less expensive one the more costly one is cold rolled 1018 bored out...i am suspect of my piece not being 1020 and maybe a36 which is a mismatch of whatever (i believe) as when Im drilling and milling it I hit hard spots sometimes that are hard to get through, lots of cutting fluid and real slow, i have only had that on the plate not the rods I get from them though. And then the benefits seem to be there are no pretensioned spots as can be present on cold rolled( no experience just reading) of which should not concern boreing it uniformly though , like I said no real experience , just bits of info I have found so am just thinking out loud here.

If you use solid stock you will have to drill the center for the stem. Most people use 2" pipe.
That's why Mechwerks labels his as DOM.
Much less work.

I'm looking at his page, and I missed that totally.

Thanks for pointing that out.

If you use a heavy wall 2" pipe with .344 wall thickness, you can cut to length, then machine the ends for your bearing races.
That wall thickness allows for turning an hourglass shape into the outer surface between the ends, if you want.

Blaksmith was selling some years ago to help folks along with projects. I ordered one with no exterior turning, so the outer surface is untouched. I plan to use it for my trike project, which will hopefully begin again this winter.

Thanks for the info

here's a link with a comparison.
