You have a lot more patience than I do, 3 times smh.
On a side note, did the ss arms seem any kind of loose on the gdh spindle? I noticed they sell them with it, but thought the ss spindle was slightly larger than 22mm.
You are right, ss spindle is 7/8" which is ~22.22mm. While Profile suggests they fit fine, I think it's more about rust on ss arms making it seem a good fit. I could install cranks with bare hands, with a couple of mid-strength hits near end. Installation tool is still included with package (and even sprocket bolt this time). It appears that new alloy cone spacers are doing their job well, as I didn't feel any flex I was kind of expecting while riding.
As I was aware of sizing issue, I have initially planned to install this crankset using polymere adhesive - which is, by design, best applied to 'gaps' of about 0.1 mm between metal parts, and thus works good with worn cranks. This crankset, in contrast, appears to be almost like specifically made for adhesive install. I'll give it a week or two and then glue it in for good.
I've used adhesive on cranks before - nothing flexes or squeaks, very solid feel. I've removed bolts a while after install, and during few years of riding nothing
has moved at all, never had to put bolts back. Cranks are still on that frame, actually, along with sprocket
Obviously, one does not simply remove cranks in such scenario - heating to ~100C is required for disassembly (there are also permanent adhesives, watch out).
It's very likely that same effect is achieved by just getting thunderbolt cranks (then you also don't need to make a 15$ custom press-fit sprocket spacer for even chain tension). But, that's too easy and new thunderbolts don't fit into this mid-school concept
As for frame, it feels great, it's indeed a shame Standard messes up while being able to do great stuff. I still had to do some work with a file..
Frame appears to be symmetric this time, though I didn't take a very good look yet
Dropouts, if anything, could be better, otherwise it's pretty much perfect.
Time will show if can hold together as well as it looks.
