The Chopper Compendium

gotta be hard to get the smell of pinesol out of the dishes after too lol . my old lady found some parts in the dishwasher once after having to wash dishes for a week and replacing the kitchen dishwasher I gained a new hot washer for the garage but dont use powdered soap either it dosent always dissolve all of it and it gets stuck in weird places lol

Getting a little more done. Made a pair of cylinders flat on top and flat on bottom with an o-ring grove.


My boring setup is a little different with the cylinder held on the apron and passed over the boeing bar.

Couldn't find the Aircraft seamless 4130 tube in the wall thickness my engineer said I needed at a price I could afford. So I bought some heavy wall and turned a few pounds off.

Sawsalled and ground the tubes off the Ninja neck as close as I could then spun the rest off.

Looks like it's ready to weld.

The first two pieces of the lower tube welded and the neck mocked up. Can't cut the front lower tube until the bearings and seals get here to put the fork and wheels back together.\

Took awhile to talk myself into drilling holes in brand new pistons.

Dusty
OBTW all those holes have peek buttons now and are fitted where even after warming on the wood stove they fall to the bottom of the cylinder.

Welded a little more today.

Dusty

Made a dozen little PEEK buttons to go in the piston skirts.

Parting off the little bowl was an important tool

Lots of fiddly work for something this simple

In place!

Dusty

Still gotta clean up the edges but they slide right in.


Dusty

Started mocking the lower end up to check Fit etc.
I will use the drive side case.

Hit the mains a tiny bit with the line lap.

Vaselined up the cages and loaded the rollers

Crank assy slid right in and spins free!

Slipped the pistons without rings.and cylinders on, amazing how free it is so far. A quarter turn by hand and it will coast a round ands a half.

Started inspecting , right off the rear piston is .005 lower at TDC than the front. Really pretty close for 80 year old cylinders that show to have been surfaced and I did a minimum cleanup on the base gasket surfaces. Need lots more checking then I can make the thrust washers and balance it.
Dusty

The left tank. Just seemed like a day to weld

Cant do the other until I get some more .040 tig electrodes.

These will make the top frame rail and be outboard of the cylinders One for gasoline and one for methanol.

Dusty

thanks for continuing to post Dusty! I've been dealing with computer issues, but I think I may be back now. I've got quite a bit of stuff to post too, so keep your stuff coming. I enjoy seeing it.

-dan

Got the frame standing on its feet. It's adjusted as long and as tall as it gets.

Started fitting the right tank -top frame rail

Proly leave the tanks just tacked up untill I get the engine in it.

Dusty

With both tanks in place.

I'll leave the tank mounts just tacked until I get the engine in it to be sure. I'll tear it back down tomorrow and tig the rest of the rear section. The ruler shows 8 1/2 " with a real front tire that's not flat proly another 1" I think I couldn't want it any higher and it'll adjust down till it drags.
Dusty

The heads are done!

Ya don't gets ta see the combustion chambers piston heads or know cam specs at this point. But I'll talk bout most anything else

Dusty

Looks good.
