This build will be an attempt to combine a ‘55 Hawthorne frame platform with a David Bradley hood.

A few thoughts in the wee hours from virus worry induced insomnia.






Hands on trial and error down the road...experimentalist at best. This concept has been floating around in my mind for a couple of years now. The red hood was sourced a couple of years ago. The rusty one last Fall, if I end up cutting one up I have a backup for error management. I’m tired of moving the hoods around so it’s time they are repurposed.

I can share from a friend's experience that a straight axel thru the fork will not work very well. Fine in a straight line but no good on turns. You may need a subassembly and a linkage to turn each wheel separately. That might steer you into class two, unless you can keep that fork stock...

I see what you did there. :21:

The drawings show that there are plans for a center pivot on the axel. That's a start, but I'm thinking that the head tube angle is where the problems lie.

Dig it MF! Your pictures are worth a thousand words!
RaT oN~!
Thanks, notice the clutter, always heard that a messy desk is a measure of ones mental quotient.
Wow......can't wait
Yah always like starting these things but I tend to be impatient.
Love the Bradley sheet metal!

The double front wheel steering instantly set my brain into engineering mode. Should pose some real challenges. It will be interesting watching the 'trial and error ' as it unfolds!
Yes I saw the first one in an antique shop and thought I have to have it. I watched the price for over a year. They finally suckered me in with a reduction sale price. Trial and error it is. What looks good on paper doesn’t always transfer to reality.

Understood, thus the pivot point. Also looking at some go cart steering knuckles. Guess I could change the name to “StraightLiner”. Nothing in the rules says it has to turn. It would be rideable but RatRod says no “Show Bikes”. The goal is make the front end bolt on to the fork.
I see what you did there. :21:

I’m anxious to see what the geometry allows to happen in terms of executing a turn. As mentioned above I’m looking at some steering knuckles as well.
Man, if I had TWO of those hoods, I'd be shooting for twin trike fairings...maybe the kind that steer with the wheels.
I’ve thought about the trike concept, it would be easier. I’ve always to late on picking up a used trike or they’ve been too far away.
^That would be cool on a traditional trike!
Agreed.
You've been doing some serious planning! How about a 40's-style Indian motorcycle (full cover) fender for that back wheel? That would flow nicely.View attachment 118141
Yep two hoods in play here, could happen.

May be fun to watch, maybe not so much in the execution. We’ll see a lot of time.
This should be interesting.
I've tried to use a bolt on trike rear mounted to a fork, it didn't work well in turns as @GuitarlCarl said of his friends build.
But I'll be watching to see what you come up with.
Trial and error ahead, maybe a couple of twists along the way. Might get started on some visual mockups on Saturday. Thanks!

Thanks all for the input, that’s what makes the projects interesting. Sometimes I use or adapt suggestions, sometimes I completely ignore them. Keep em coming.

Wow, that’s pretty close to one possibility. Thanks.
You must have went back into Fresh Finds for the original bike picture...follower dedication. Laidback from Wayback,Thanks again.

Not my rendering but @horsefarmer is on track with his. Thanks.

Thanks, I did use your previous build pic. What surprised me was all the photos of David Bradley hoods online!
