How do those rear brakes work?

[truckinduc]

ok so I decided to start on the bike again. I got some ti filler rod, and Ive decided to use the 748 swinger pivot.

Started my swinger eccentrics today, as well as the frame mount to the swinger pivot. other shit too.

How do those rear brakes work?

Are you asking how it literally works? or how it works performance wise? 

It works just like its on the rear wheel since its attached to the front sprocket.  Its spinning 2.6 times faster than the wheel so it can be a smaller diameter but stronger.

I dont have a cable for it yet so right now im running it as a hand brake. but its smooth and linear and will easily lock up the rear wheel. BTW does the rear wheel look familiar?

[truckinduc]

pieces for connecting the swinger pivot and frame.  Im going to further narrow the cases and re make the adaptors from steel, but that can all be done after the frame work.

the steel pieces at the ends of the shaft get welded to tubing that meets the motor mount right above them. Just like on the Ducati SBK models.

Makes sense.  Just never seen a rear brake set up like that before.
Glad to see you are mobile again and working.

BTW if I won the Powerball, I'd build you a shop with the best of every tool you could imagine, and just sit back and watch you work in amazement.  Keep up the good work :

Well thank you. Im having trouble finding enough time to get any real work done lately.  I gould gladly build bikes all day.

Im turning the swinger pivot adapters out of DOM on the cnc at school.  Going to see if I can get my hands on some 4130 round stock and plate.  Then its frame welding time.

[truckinduc]

found an hour to work tonight.

Get the front end and swingarm geometry I wanted.



Getting it at 21 degrees rake and 11 degrees for the swingarm angle.

Then you cut more.

[truckinduc]

what you people think?

[djrashonal]

are you gonna weld an additional subframe to that for the engine mounts?

[truckinduc]

Swingarm eccentrics started.





mock up rear motor mounts



rake

[truckinduc]

here is the frame design.  off or the main frame will be a Ti subframe.

[truckinduc]

not the best way but it works.







going to have a little chain line issue but i can fix it.

[truckinduc]

got the other side cut out and bent up.  Slowly getting somewhere.  I tried getting filler rod but the place i got it before was out.
