Braze or weld ? Snag 12-12-2009

Got the grandson a new BMX bike for Christmas , and he wants stunt pegs on
the back . I've got some SS tubing that will make some very nice pegs , but
I need to attach a stepped washer to one end - the washer will go under the
axle nuts to attach the pegs . I don't have any SS wire for the MIG , so it
looks like I'll need to use the OA rig to attach 'em . I've got a couple of
varieties of brazing rod , and some pieces of SS that I can cut into narrow
strips . I'm not sure which alloy any of the SS is , thus the question -
braze or weld ?

I guess I could make cup washers
and thread the sleeves ...

brazing ~should~ work fine but idk if i would feel comfortable with it
being
brazed. honestly i dont see how it is cost effective to try and make
these as
apposed to buying them. its cool and all you want to make them for him
but i
just dont think the time and materials you put into them are going to
produce as
good of a peg as is already mass produced. also since he just wants them
on the
back you want gnarling or some other form of grip on them. there are 2
styles
of pegs if my memory serves me correctly, textured and smooth. if you want
to do
a lot of standing or riding someone else on pegs you want the textured, if
you
want to be doing grinding on rails and such you are going to want the
smooth
ones.

maybe prices have changed a lot but i remember pegs being in the 20 buck
range
when i got my bmx bike, granted that was like 8-10 years ago but i doubt
they
are much more expensive now

Hey , you miss the point ... I WANNA make these ! I've got the materials
on hand , and have the machinery (mill and lathe) and tooling to do the job
right . Including two types of knurling tool .
I'm leaning right now towards making a cupped washer to go under the axle
nut and threading the sleeve onto it .

If you braze make sure that there's plenty of surface area for a bond --
it's not necessary if the braze is perfect, but if it isn't...

"Where'd you get the hole in your ankle Scooter?"

"My Granpa made some stunt pegs for me ..."

(yea, yea -- now I'm being a killjoy. Were it me I'd still make the
pegs, though).

well dang if you have knurling tools then by all means, i was expecting
you were
just going to braze on the cup washers and just slap them on. i am all
for the
hand made factor (heck all of the xmas presents im giving this year are
hand
made... guess i dont have much option though being a poor art student that
has
access to a full glass shop and a full metalsmith studio ;) )

and mr. wescott, i have to think about cost effectiveness because of all
the
toys i "justify" haha
