Todays Project - What did you do today?
Invited a new friend from one of the motorcycling forums I'm on to come over to the shop with his Frankenbike project. Neil is an "ex-pat" from the UK (Manchester area, IIRC) and is building a custom bike from several. He's got a "Smithy" 3-in-1 type machine at home, but it's too small for this part of his project.

Today he brought over the rear swinging arm from an Aprilia 250 GP bike, to be fitted to the frame of another bike. I think it's a Yamaha RZ350 frame, but I am sure that twin-cylinder two stroke motor is the one he'll be using. We had to take 4.5mm off each side of the swingarm, at the pivot points. This will allow the Aprilia part to fit between the other frame. There are NO square or straight surfaces to reference from, so we first turned a plug out of 6061 aluminium and bolted it to a plate of the same. This Ø32mm plug just fit into the bores for the needle bearings which the swingarm pivots upon. It gets the pivot axis somewhat square and perpendicular to the table, aligned with the spindle of the machine.

We used lots of clamping, including use of two of my Starrett No.190 & 191 "Little Giant" Jack Screws and one of the machinist jacks that I made as a freshman in vocational school in 1973 (and had never actually used before today.)

Here's Neil doing the flycutting on one side:

Then the other:

Neil reported that when he got back to his shop, the part "fit like factory parts". This made me happy, and well worth the 3-1/2 hours we worked together on it. He didn't have to, but he brought me a round (casting?) of some naval grade of bronze that's about 2-1/2" in diameter and about 30 inches long as "barter." I don't know when I'll have an application for such a material, but you know how we all are about "stock". Big Grin

Thanks Neil!

I've asked him to join up here, though I know he's got limited time. He works for a large volume casting company out of Spain, and travels an awful lot. When home he also likes to ride motorbikes, but mostly on the track.
