i'm going to do some remodeling on my 86 CB450SC frame but before i start cutting does anyone have a frame already cut open that can measure either the wall thickness of this 1" O.D. (25mm) tubing, or can measure the inside diameter?
specifically on the frame hoops that hold up the original tail section.... thanks.

It's a thick wall tubing is all I know and I believe it's also seamless

Will a 78 cb400t frame do? I've got a damaged frame I can cut to measure if needed.

thanks for the offer bro, i ended up ordering a stick of 1" x .065" DOM from the onlinemetals sale with free shipping promo. it's for a solo seat hoop with pair of gussets at each intersection for the shock mounts. i figure .065 wall should do it. i'm not crazy about this NH frame look but don't really want to reinvent the hoop.
