hallo crankbuster

have you seen as there is a version V 2 Axle Z 5 / Z 4
this Version is using the same inner axle as the one for the Z 8.
just the bushing to place the gear Z 5 / Z 4 is added.
this version is giving more possibilities for adjusting the aligning for the gears Z2/Z3 - Z5/Z4 and Z6.

I would prefer to work with this ...

beat <212

( BTW, if V 1 would be made, it needs to have a hole of 8 mm in side ) :ok

It's not about the money Beat, though costs need to be covered. I like to make things for those that deserve it, sadly the toys needed are very expensive.

. Probably best to private message me for his details. He's an engineer by trade said it wasn't that hard but did have to machine new cases plus a spacer. Sorry I lost him on the technical side of things. Told him about you and the forum and he said he would be willing to talk if you want.

Hi simon,

yes, a neat solution for the electric starter.
I guess it is dough fraser ore something the name of the gentleman was building it.
congratulation to him for he's way of doing it.

but: my target is a other one, as I said in above:
my el. start must be a add on, - no cases modified, no internal parts have to go on the bench.

the only mods will be done on the primary drive side, means the engine can stay in the fraim when the ad on starter getting in place.

so, - there on I am, and it looks not so bad by now,

beat :lol:

Good to see some photos of Doug's latest, at last, not much about officially, as yet.
In issue 64 of Old Bike Australasia mag there's a photo of him arriving on this bike at the 12th BSA National Rally held at Beaudesert, QLD in October 2016 (followed in by what might be Steve M's B50 judging by the tank stripe), the caption goes:
"Doug Fraser arrives after his marathon from Melbourne."
Melbourne to Beaudesert is over 1600km by the shortest route (Newell Hwy), indeed a marathon on knobby tyres <216

hi all,

the flywheel gear ( No. 9 , Version 2.4) is fitted and engine is running with.
additional 62 teeth for el. starter device
additional 62 teeth for el. starter device
but there was a unknown problem coming along.....
blueprint the clutch pressure plate
blueprint the clutch pressure plate
by pulling clutch, the PES pressure plate was touching the old CCM cover at the inside .
this may be because I do use 6 friction plates in my basket and the measurements of the 44 year old CCM primary cover are not made to cop with this mods....
the inside of the CCM cover
the inside of the CCM cover
after grinding off some material at the cover and cutting 1.5 mm off the pressure plate the clutch was working ( disengaging ) properly like before.
smal mod on the pressure plate
smal mod on the pressure plate
a first test run was showing everything ok, evan the generator was supplying the el circuit properly.
so the fitting the stator to the cover in state of fitting it to the crankcase seams to work fine as well.

just one negative point it shows again: this old cover is leaking oil right trough the cast :!:

I did some more welding work on my primary cover to get it oil tight.
The adjusting of the stator, centering to the rotor, is easier to do as in original.

and the most important thing : IT IS NOT LEACKING OIL ANYMORE

thank you minety, but I try to build a starter device for a old motorcycle and not one for a B50 Bomber.... :grin:

so it gos like this:
sawing a pice of alu

grinding it for the shape it fits the plan

cut out the sidecase ( with some help as to see )

next will be, welding it in place and then cutout the cover as market...

the question is not : HOW IT ENDS, no , - because it will end with a electric starter on my B50 .

the question is : WHEN IT WILL END

for the next step I do need the gears made by PES and some more alu bars from alu-verkauf.de .

so for now, - I have to wait.........
<203

BTW, the next days I have to solv a bit a strange problem on my project:
by mod the cover for fitting the stator to the cover I was using a " tool " for centering the new plait.
centering tool
centering tool
plate on tool
plate on tool
centering tool in position
centering tool in position
plate in place ready for welding

after the first weld
after the first weld
set stator gap trough the window
set stator gap trough the window
yes, it is no problem to set stator in perfect place, but this " window" is NOT exactly in the center of the flywheel !
but I do need this centering spot on by let say 0.05 mm. because the gear Nr. 8 must be 90.177 mm above this flywheel center.

hmmmmm, let se what the next days are bringing....

So what you thinking beat? Some sort of fly cutter/reamer/borer centred on the crank?

Why do you need the hole in the cover for that measurement ?
Can´t you use a Zirkel ( cannot find the english word for it) in the centering hole of the crank with the axle distance to mark the position ?

beat, you must have access to mill ? with out this you cant bore all the holes for the other gears, bearings etc ? clamp the left crank case on the mill and clock up the bearing. put the clutch case on (this must be doweled for location) then you can bore the access hole in line with the crank. then index over to the other hole centers.

I got it" Zirkel ", yeas, but it all is making it with a " parallaxe ", so it is not exactly enough...
stew79 wrote: you must have access to mill
yeas, I do have access to a " mill " ( drill ). but it is a hobby - machine, very small and cheap :oops:

as my cover is positioned with 3 dowels to the crankcase, means if the crank center is set, all the rest can be done with indexing as you say stew.

BTW, dos anyone have made some experience with CFK ( the carbon stuff ) been used on a engine ?

hi beat, for the benefit of this very well thought out, but complicated project, i think you must do all these holes etc on a proper accurate mill, or get a machine shop to do it for you. to spoil it with errors in the position of things (or even the head not being square on your drill) will be very disappointing. a normal machine shop can bore the holes to precise position, size and depth. (i presume there are 2 rows of blind holes that take the bearings ? that must be in line)
stew
ps or ask Santa for a bigger mill, with some good tooling ? :thumb
