Re: [RBW] stripped braze-on

2014-12-24 Thread Geoffrey
I think using a nylock, putting a screw all the way through and using that 
as a sleeve to contain the screw will lead to problems down the road.  If 
that screw is in there, slamming around and you bounce down the road, it's 
a shock on each bump.  The cheapest fix IMO that would be really secure 
would be to find a 6mm tap and just go oversized on those and call it a 
day.  My two cents.

Re: [RBW] stripped braze-on

2014-12-24 Thread Joe Broach
Geoff,

The bolt (might need a button head for clearance if drive side) and nut
properly tightened will hold rack to braze-on with clamping force. It won't
budge over bumps or cause any problems. Lots of older bikes have unthreaded
braze-ons meant to be used exactly like this.

I'd go this route in the OP's place. I do this on perfectly fine rack
mounts anyway. Belt and suspenders approach.

Best,
joe broach

2014-12-24 Thread Geoffrey
If you do chase the threads, make sure you get new hardware, bolts stretch 
over time with use and that could contribute to your problem.

[RBW] stripped braze-on

2014-12-23 Thread Mobile Bill
Hope y'all are getting some time off for riding. In the 70s here, but 
raining cats and dogs for two days, so working on my bikes and looking for 
the most practical, creative and immediate solution to a stripped braze-on 
on my Betty, unfortunately the BO to which the rear rack attaches. Don't 
know how it happened. Just noticed the rack was loose, and that I could 
tighten. The 5 mm screw was a little bunged, as well. Tried another screw 
and it gripped a little deeper, but eventually started spinning as well.

2014-12-23 Thread Chris Chen
You can try chasing the threads with a M5x0.8 tap but you may need to
repair it with a helicoil insert, like:

It sounds scary but it's not that hard.

Without a pic I am guessing you mean the threaded cylinder brazed to the seat

Maybe just use a nylock nut with a new bolt? Is that ok to use for a cylinder
