A question came up last night.  Does the 15 deg. rule apply to production machines?
"In all classes other than Production and Modified Production, fork stops must limit fork travel to 15 deg. right and left (30 deg. total)."

Willie,
Front end design using a "Trailing Link". You need to be concerned as to what happens to the rake angle and that will change with the length of the swing arm.
Terry  :-D

Neat, so is that using like a car spindle and back spacing the wheel so it is center??  If so that wouldn't be too hard to make.

There are many ways to build a hub-center steering.  Solo hub-center steering is a lot different than one for a sidecar.......we have build both....... and they take a lot of track time to get them adj. to one's liking.  Most of the early
solo bike streamliners used hub-center.................
Craig Anderson's sidecar streamliner uses a hub-center and appears to work just great. (at the present time Craig holds the 1000c.c. AMA sidecar streamliner record) we will see more
sidecar records broken with this outstanding
 liner.  Hub-center in both solo and sidecars allow more adjustment options (again depending how it is done and build) One of the foremost experts on sidecar hub-center steering
is John Renwick from the U.K. ....John build a hub-center sidecar
roadracer back in the 1960's before most people
had thought about them.  John will have his new
sidecar streamliner at the 08 BUB..........between
Craig and John I see no problem for a 250 +mph
1000c.c. sidecar record in the future.......................

sumner i thought about a "car" spindle but it puts the weight on one side of the chassis --yea radiation and chemotherapy will do that to you --------willie buchta

The picture shows the spindle attached to an arm that goes around to the front and pivots on the both sides of the frame.  Would that put the weight on one side especially since you are centering the wheel/tire on the spindle??  I'm trying to visualize the forces.

Congrats on making it through the rad/chemo and being with us today.  I'll bet that was harder than building any bike you have built,

Sumner, most sidecar hub-steering uses A-Arms
so Wille is right about it putting it on one side.
Think of it...........taking one corner off a car and fabricating it to a center frame.......However, there is a lot more involved.......one probem with sidecar hub-steering that you do not have in solo-bike hub-steering, is what we call bump- steering................. it gets rather complicated......
Any one interested in fabricating hub- steering for a sidecar feel free to contact me.....glad to help...........we have no secrets..................................
Glad you are doing well,, Willie...and Happy Holidays to you and yours........................................

The more complicated you make it , the more you have to spend time on it.
A front tire from a TF car can do very well on most 2 wheel bike liners, and all with store bought stuff. :wink:

I'll second what Willie said.  Yesterday a box arrived and it is indeed a thrill to see the contents.  Maybe to someone like JackD, who goes to Bonneville and sets 10 or 12 records in a day, its no big deal.  But to us bottom feeders its the thrill of a lifetime.  My thanks, too, to Cliff Wheeler and the SCTA.
Get off the stove Grandad.  You're too old to be riding the range.

actually sum if it wasnt for the cancer i probably would never have raced at el mirage or bonneville --i was going to one day but that day just never came --now im just trying to do all of the things i put off all those years --i am thankful i got the chance and urge everyone to do it today tomorrow may never come ---merry christmas everyone    willie buchta

I lost a wife to cancer when she was only 32 years old long ago and learned the lesson you are talking about then.  Within reason I've tried to live my life at the moment with no expectations of being able to do something at a later date. 

............and a merry Christmas to you and the rest of the guys on here,
