So after hauling and spreading 60 bags of mulch, I was all ready for my nap but noooooo....

the park bike clamp arm I bought used arrived a day early....soooooooo..the the plan is to incorporate it in with speed rail fittings. but of course the arm doesn't have the right dimensions..now the fun part begins..:congratulate:..


first disassembly and a little grinding the hard edges and sandblast

now since schedule 40 1 1/2" pipe had a different id than the factory arm it needs some trimming. it is a big solid bar so no problem there....(it will work with 2" but everything I have uses with 1 1/2")

now on to the mount. grabbed a 5 1/4" piece of 1 1/2 aluminum pipe and milled a slot for the locking mechanism.

cut a 4" piece of 1" 1/8" wall for the holder and band sawed a curve. not to worried about fit since Can weld any gap.

got that welded up...hit the inside with a die grinder to clear both paths...

now to make the locks...two brass rods about 2" long..one with thru hole one 3/8 16 tapped. then a bevel on the inside ends

unlike the factory ones that can fall out when not locked I made mine so the bolt for the lock keeps the arm in place...so back on the lathe to get just enough depth on the bolt groove.

now a delrin back bushing to support the arm tang....3/4 drilled...cut to fit 1 1/2 pipe with a bit of a flange..just because..

pressed in .006 tight fit

assembled....have an orange adjustable handle coming from mc master for the lock :)

IMG_9424.JPG

slips right into my 1 1/2 grip rail fitting.. this allows me to mount it just about anywhere ..oh new pads for the clamp should be here soon too..

arm $55 inc ship
new pads $10
3 hours machining welding

i filled the bottom legs with scrap brass and lead smothered in construction epoxy.

I got the park tool tray for it...coincidentally it fit the main tube perfectly...even i was surprised

adding some red parts to my daughters ride.
