couple of considerations you may have already thought of.....make sure spring has side clearance to frame side....it will have a sideways rocking motion......maybe have spring cross member adjustable to fine tune ride height? or maybe your rear heim jointed link does that already?

 

[TomyJ]

RebelRouser

Getting closer...Tying in the upper rails are next...

 

[TomyJ]

RebelRouser

This is going to take some time and maybe a rocker type end on the shock top for more clearance?

 

[TomyJ]

RebelRouser

More mock up, Things to do this week...Maybe I should install the upper rails then the coil overs?

 

[TomyJ]

This one is simple and much weight and height. This is lower and compact to the rear and the weight of the shock is also supported close to the frame, I think I will go with this one? Please feel free for input...

 

[LarryA]

do agree w/staceyb about linkage ratios, thinking, for the long swingarm lever the 2 red coil overs looked as they had travel that matched the lever......another disadvantage with the rocker arm setup is 5 pivot points vs 2 with the red shocks.....true, will have higher cg and space taken up that may be needed by some other component. one idea... swing arm turned over with red lever pointed down..... yellow shock fastened to center of swing arm crossmember, shock angled forward and down......link rods fastened to red lever ( that is now hanging down) link rods travel forward and up to meet a pin that ties link rods to both sides of shock, a guiding tube or mechanism would control the tie bar, some what like a crosshead on a steam engine, as the shock pushing forward pulls the link rods forward,which pulls the red lever forward which pushes the rear wheel down, thus suspending the frame.... LOL hoping this makes some sense?

...You just gave me a headache...

PS I have not seen this idea used before, probably with good reason!

I will be having another glass of wine or two, or as my wife says< Is it wineing time again...

OK, OK, Ok... One more mock up, then the upper frame rails and upper control arm brackets, then mock again with steering, And will be on the ground at this point. Dec 30 is motorcycle swap meet, I'll be looking for twin shock and jack shaft sprockets, 3.5" and Harley 530 chain and Honda 520 chain AND...

To all of you my friends Thank You and Happy New Year... With all our trikes running in 2019

i would think most sprockets you will find at the swap will be splined... i would opt for sprockets with a bore an a keyway then you dont have to find the splined shaft for them not expensive new.. graingers or similar place ....

 

[TomyJ]

RebelRouser

And the winning design is and the support will line up with the upper frame rails...:Santa:​

 

[TomyJ]

RebelRouser

Upper rails will be next with upper control arm brackets and vertical 18 degree bracing...

 

[LarryA]

what i tried to say!

what I was trying to say......not far from what you have chosen.

 

[TomyJ]

RebelRouser

With seat? Maybe to low?

 

[vwbug72501]

With seat? Maybe to low?

All motorcycles are invisible! Fact of life.

If you are sitting too low and riding to the right of a cage (especially soccer mom minivan/SUV), most of you will be below the window line and therefore even MORE INVISIBLE!! :xzqxz:

Just something to consider.

 

[TomyJ]

RebelRouser

I really like the mustang seat for comfort and now you can see the direction I am going...

 

[TomyJ]

RebelRouser

This is the way to go for my build, coil over and pull rod is just off center to the right and the swing arm brace left side will play host to the jack shaft mount, again guys this is still in mock up with all tack welding. Now notice the upper shock mount it was going to thick steel and brass bushing, Butt I decided a extra heim joint should do the job??? What do you guys think???​

 

[LarryA]

I think a heim would work! top rocker arm bracket will need to be strong, it will carry almost all of shock load if I am not mistaken.

 

[TomyJ]

RebelRouser

Tomorrow will be a little paint and tack welding the frame and brackets I hope...:clapping:I still hope to have it rolling before next Tuesday...​

[TomyJ]

RebelRouser

Getting closer to add the final measurements and weld for the swing arm set up to the frame...​

 

[TomyJ]

RebelRouser

Damn, One step forward and two steps back, swing arm bracket wants to hit the shock bracket, so I'm going to center the shock to the swing arm bracket and higher mount and try dual pull rods??? And keeping an eye on the location of jack-shaft area...

 

[TomyJ]

RebelRouser

A little higher at the top of the shock and one push rod on the outside so I will add another...​

 

[TomyJ]

RebelRouser

More higher and now to far out, this part of the build is giving me the FITS (pooop) I am working with the machinist this week for this bracket ( and order 2 more heim joints) and the upper frame rails with the 30 degree kick out to clear the engine...​

 

[TomyJ]

While the machinist is making new brackets for the shock top, it will give 15-20 degree angle then I will rework the bottom mounts. Mean while I need 2.5 inch clearance for the angle for the upper rails so the front rails will be 8.5" wide and flare out for the engine clearance to 16.5" wide and tie in the swing arm brace, I hope, just about ready for the upper control arm brackets to be welded on, install the arms, brakes, steering, AND start fighting the front coil overs... :Shrug:​

 

[LarryA]

I am assuming the rear wheel sprocket and jackshaft assembly will be on the wall side of the Rebel......don't remember seeing a mockup of the jackshaft?

Good eye Larry, You are right, But I am hoping to sell this as a rolling chassie, they pick the engine and install with jacks shaft I am looking forward to my next build, Shenanigans, the sit in to drive, I like the building of them, safe and strong, .125 wall square tubing...Did you get any snow chains and a ski? EDIT: Cut a snow board in half and add it to your front wheel, Then add a couple of these, Now you can ride year round??? :clapping: heeheehee… Have fun my friend and ride safe.

 

[TomyJ]

RebelRouser

Machined upper shock brackets that will give me a 15-20 degree down sloop, then mock up, then double check lower shock brackets, all tack weld, then move back to upper frame and control arms.. YEA!:clapping: getting closer to a rolling chassis...

 

[TomyJ]

RebelRouser

Yea! That's me ready for the tack welding of the cross member that joins the swing arm , the lower frame and the upper shock brackets, and later the jack shaft...​
