New Build Cool Stuff

sweet! question: what are you doing, about the rear coaster brake? not having access to a real shop w/real equipment or time to use them, i had to use 3 rubber spacers between the wheel and sprocket, to clear the chain away ffrom the 3" wide rear tire.. because of that, the coaster brake arm wouldnt fly. had to grind off the arm, and just keep the middle. and because of THAT, the nut wouldnt lock. wheel always coming loose and bearings going bad. i finally got pi$$ed enough to just ditch the rear and go for regular 26" w/2.25 tires.

Spunout, this bike is a real pain in the butt to set-up!!! follow-up on the posts, and you'll see what I did to resolve the problems...This wil be the "Big Meanie" you so appropriately named!

Best regards,
Jim

Good looking web page Spunout I like the snow effect , very nice and cool.

I got the replacement intake finished...It will get a fine TIG weld around the tube. I never have liked the factory piece with the crook in it. This should flow much better.

There is "clean" area at the bottom of the carb socket just below the slits. I machined a groove in the end of the intake for an o'ring. There shouldn't be any problems with vacuum leaks.

More to come,

Jim

Seeing the mounts and the sprocket & clamshell mount for the rear wheel first hand at Jim's shop was something else. Motor mounts need a little streamlining but great function for a one-off. Like I said before, the clutch kits aren't going to be the only great things manifesting out of Jim's shop.
I've got some great ideas we are working in conjuntion for as well. I just can't wait until the 10,000+r.p.m. billet head motor is born. I'll have a grin as wide as my handle bars on my chopper then.
Keep up the good stuff , Jim. =-]'

Jim, I still have to wing it with the manual lathe and mill. It's the only way I have ever known so its not to bad. I do like going over to to my buddies shop and watching the C.N.C. stuff.
I always say if you never have to scrap anything, your not making many parts.

thank you. not bad for free, you know? no 'buy now' or shopping cart options, though.

CE: that intake is killer. puts mine (below pic) to shame.

with it being both shorter and not having a sharp bend, as a guess, how much do you think your flow has improved?

Thanks,

I do design/machine work for a living...lots of tools are required in the machine shop trade, that's the only way I can do this stuff so easily. This was supposed to be my bike. Even though it is sold; I have some time, (I'm not doing anything now anyway), so I decided to do up this bike as though it was going to be mine. His final bill will be around $800.00.

I really don't know how much it will improve flow...but it should be substantial. The thing is I have not run this engine so I really won't be able to say one way or another if it actually improved anything.

There are several shops on my street...we all get along...borrow each others stuff etc. Sometimes I'll go in and see one of the guys spend hours on the CNC doing something I could knock out in 30 minutes on a Bridgeport. Sometimes "modern" machine shop guys forget the old ways are what won WWII.

The CNC is great for the short production of fancy shapes, but it's not the "everything" that a lot of people think it is.

If I had a product that was going into high volume production, I probably wouldn't even use CNC technology...Give me a wall full of Cincinnati's or Kearney treckers any day.

I've got an old No.2 Brown & Sharpe screw machine that will run circles around a CNC lathe...It's all in knowing how to set it up. I made the cams for the clutch kits on the Brown & Sharpe. The CNC guys wanted $3.00 ea. I was running them at a 35 second cycle time or about fifty cents each. The O-1 tool steel scared them off.

CNC has resulted in a lot of the younger guys knowing nothing about basic machine shop practice.

Nice lookin intake CE. Does it open up to match the intake port on the cylinder?

I sure do wish I had the means to do some metal work in my garage.
