What length
and diameter do you need
exactly?
200 mm M8
studs are an off-the-shelf item, for example. So are
200mm M8 bolts with
101,000 psi rating.
McMaster Carr has a pretty good stock of this sort of thing.
Hi
Bill,
The bolts are M10 x
1.0 thread, which seems to be the problem. I took a very quick
look at the bolts from the dissected single rotor, and they're about 140mm for
the longest, and maybe 135mm for the others. Note, this was not
carefully measured, so don't anyone go buying bolts based on this.
The only thing I could
find at McMaster Carr was full threaded studs, with the description
below. It works out to about $8 per stud. I was
able to buy one set of custom manufactured bolts recently, and they should be
here any day. They were $116, so just about inline with using homemade
studs I guess. I have to believe there's a sources for the
exact bolts we need, but I haven't been motivated enough to find it
yet.
Cheers,
Rusty
