Allright.. so we are back at it.

Regarding the brakes..
As said earlier a new center for the disc is necessary. This will be done near the end of the build. I also want a new rim for the beltdrive..  the outer one,  to center the bolts better.  
This will be done together, and perhaps more things like these will pop up the coming time so then it can all be ordered at once.

Also had a long talk with the builder about the bracket for the front caliper. He is a well known builder here in the Netherlands, and has many published builds in magazines but he usually works on Harleys. He has been doing it for 25+ years. The last bike was a build from the ground up starting with nothing, of which he has done many.

He is adament that it will work and is strong enough, and the weld is proper.  So I will trust him.  I have known him for many years and so far anything he has fabricated has never failed. Nor have I seen any of his custom builds fail.

The bike will not be ridden that often, and we'll make sure to check it regularly.

The release valve has come in aswell..
It has been pre-set to 14/15psi.   Now time to weld that into the plenum.

Work is also progressing on the drive for the charger.
Because we do not want the cover to warp, a steel fixation ring is created to keep everything in place. We do not want to use the stator for this, due to the heat and risk of damage etc.
It will be welded in small increments to hopefully not create any distortion.

The dimensions for the rollerbearing and the oil seal have already been machined into the bushing.



Will machine it down a little bit  

A quick pic of a rear shock on the bike..  

DennyZ, this build is slick.  Lovin the header and of course the huffer.  The reservoir with the blowoff valve looks like a good idea.  I don’t know much about superchargers.  Does the blowoff have enough capacity to protect the blower in the event of an intake backfire?  Your gonna need a serious clutch to hold the power.

Very nice work.

Hey moderators, is there any reason why this build is in the Café?  Shouldn’t it be in Rubber Side Down?  Not complaining, just curious.

The work continues.
The shaft for the pulley has been machined. It looks great.. and very solid. Only thing is..  It sticks out of the cover a little too far in my opinion. (forgot to take a picture with the cover installed, will post tomorrow)

The cause of the total width has to do with the width/dept needed for the oil seal and the rollerbearing.

It also has to do with the width of the pulley itself. There is thicker part in the middle which can be machined down which will take off about 5mm.

Plus going to look for a 10mm rollerbearing insteady of the current 15mm. Some of the tolerances could be a little tighter aswell.

The goal is to bring the pulley around 10/15 mm inwards.

For now, a few pics:

Thanks Ohiomoto!

Denny,

When you mention that you are considering a switch from a 15mm bearing to a 10mm bearing, I assume that you are talking about bearing width.  Do I have that correct?

If I understand correctly, you intend to use a roller bearing.  That’s seems like the correct way to go since the left side of the crank must be free to move right & left to accommodate the differences in expansion between the steel crank and aluminum case.  The right-hand main bearing also serves as the thrust bearing.  It keeps the crank located axially while the left-hand roller bearing allows the crank to move axially.  Your additional bearing will need to do the same.

Have you put any thought into bearing clearance and how it will work with the stock left-hand roller bearing.  The left-hand roller bearing has about .002” clearance by design.  You can move the crank up & down about .002”.
