Rear wheel

So the transformation from a fancy pile of stuff to a wheel begun.

Step one, the parts:
# The now refurbished rear OEM HD hub with new bearings and shiny black powder coat
# A shiny Akront rim
# A set of new chrome spokes



Step two, lacing: Basicly to get everything in to place




And a while later a laced wheel was a reality




Step three, truing: Yours truly halfway ready truing and almost ready for a mental institution






Step four, completion: But after lots of anger, adrenaline and instant coffee the wheel was both round and straight





Straight like ruler in the frame


Now the tire must be a part of the setup so the rest of the mockup can continue.

Blackout

Finally the decision fell in the issue with the hubs.
A nice layer of black powdercoat became the final touch.
Now I'm gonna lace them it to a used Akront 17"x 5,0" rear rim and a new Morad 21"x 2,5" front rim.
But first some new fresh bearings will find their new home in the hubs.


Handle the bar....

So the handlebar issue was up on the Sportster build. I'm using Buell handcontrols and they are for 7/8" handlebar and the Harley risers I'm using is of course 1". To solve this I bought one of those new hip "fat bars" and they are 1-1/8".
So the very labour intensive job to take up the 1" Harley risers to 1-1/8" begun and for this I used a adjustable hand reamer I borrowed from my nice garage neighbor Bo.
As I mentioned, a very labour intensive job but some hours and a gallon of sweat later I had a perfect fit and it looked awesome.
In the making...

The perfect fit

Rear rim

This winter the Sportster project will have most focus in the speedshop.
Last year I bought a old used 17" Akront rim instead of the 16" I started with. It was in ok condition but needed some TLC to take the shine back to its former glory. First with machine polish and then some fine polish by hand and now it looks like new again.
Aluminum is a awesome material, if you are willing to put in the hours you are always rewarded with the unbeatable alu shine no matter what state the parts was in before.

End Of Season Run...

So the 2015 season is coming to an end.
There was time for "End Of Season Run" this past weekend.
I met up with all the +300 others but I took a pass on the run.
But decided to make a nice one man run in the crispy, sunny autumn air.
I got a amazing day in the saddle so now I have enough energy to last all the loooooong winter here in Sweden.
Let the darkness and instant coffee come!
(Yep, next year I MUST have both headlights on. Stupid (previous?) law here in Sweden not allowing two lights on a bike.)

High vs low tech

Circumstances made that I ended up with a magneto Ignition in the Speedshop.
So, the question is now, should I use it?
The thought of use the whole scale of technology is fun. Electronic fuel injection AND magneto Ignition.
Talk about each end of the scale.

And of course when Bombus Speedshop is involved there MUST be modifications of perfectly good parts. And this time the magneto must be rotated 90 degrees to fit "inside" the exhaust loop.

Hubby days

Bought a rear hub for the Sportster project a while back and when I came home from vacation it had arrived.
It was in a quite shabby state to be honest but that was expected.
I put in my lathe and gave it a treatment and soon it had its former glory back.
Now the final question is if I should powdercoat the hubs black or if I keep them as they are.
Time will tell...

The shabby hub that arrived


Finish in the making

And the not so shabby result
