That slot and the half one like it at the top represent where the hoops will be welded into it at the back. After I make the metal version of that bracket, I will drill some holes in it to lighten it up some!

looks good man! keep it up! I always use naysayers as "fuel to the fire". I run into that at work sometimes so then I bust my ass to prove them wrong. In the end, if it fails, then you can at least be happy that you tried it.
can't wait to see it fab'd and welded in there!

I have to say it did fuel the fire and also pushed me to do more research before tackling, which in turn got me to this point! So I thank the nay-sayers!

Re: Come On Eileen!....MONO-PROGRESS!
Man I remember those days! I did math for at least a week straight. It was fun though, it really makes you realize how a build can go from a resto-mod to a full custom....it's the foresight and planning, and a little bit of artistic vision thrown in. I like your design set up, it looks great dude! Gretta is gonna wanna F*&k your bike when it's done. Nothing like lesbian moto-love!
Good work brother!

I think you just invented a new sexual category, I will coin the name: mech-erotisism!
I can't wait to get her up around the Ham to roll around with Gretta, and you will have to bring Gretta down to the coast!
Thanks for the props!

Re: Come On Eileen!....MONO-PROGRESS!
I love the melding of modern sportbike components on vintage UJMs. Anyway, I'm no engineer, but will the shock compress properly with the proposed set up? It appears that the swing arm's upward movement will just push the rear of the shock up, pivoting off the shock's front mounting point, instead of compressing the spring?

Re: Come On Eileen!....MONO-PROGRESS!
No, it will be forced to compress in order to articulate! The rise of the mount along with the distance from the axel to the mount in relation to the pivot point of the swingarm create a long distance of leverage to overcome the "stiffness" of the shock. This setup allows me to use the physics of rising rate theory with out using the linkage from CBR setup. The lever length and the angles involved should (according to my calculations) work great with the spring rate of the CBR shock. The loads transfered to the shock through the lever length should be close to the same loads exerted on the shock in the CBR's setup. The only difference is that sense I eliminated the linkage my overall swingarm travel will be a little less.

Re: Come On Eileen!....MONO-PROGRESS!
If you'd change your bracket in a way that moves both
shock pivots let's say 1.5" back (I mean the lower shock
pivot into the edge of your triangle), the suspension was
exactly the same at "comp" but softer at "full", i.e. pro-
gressive without being harder than now.
Best regards

Re: Come On Eileen!....MONO-PROGRESS!
are you going to weld pieces of the bracket togther or bend it on a brake?

You know, the angle at which your mock up sits, looks just like my Buell's monoshock setup.

Re: Come On Eileen!....MONO-PROGRESS!
Falling rate suspension was used by Kawasaki on MX bikes, they snapped frames pretty regular.
If you had bottom pivot higher it would end up rising rate but have less leverage on shock.
Your swing arm design looks plenty capable of handling stress, may have to beef up frame though?

Re: Come On Eileen!....MONO-PROGRESS!
WOW! I am out for a couple of hours and my thread got bombarded!! Heheheh!
Well, I will try to answer and thank all the supporters!
First off: Thanks Supporter!
Now:
scm, see biker_reject's comment and look at some Ducati mono-shock setups! Degressive, maybe; work, YES! I have spent a lot of time working on this and seeked outside wisdom to create the final design. I am very confident in it!
JRK, 3/16 inch cold plate steel, cut from one piece and shaped on a brake, I have a friend who fabs decorative steel column and beam brackets for churches and other structures with exposed structural architecture.
Basement rat, that should answer your question too!
PJ, enlighten me if I am wrong, but I am using rising rate at the position I am in now, with the shock completely compressed I come to perfect 90 degrees angle between the plane of the shock and the plane of the shock mount in relation to the swingarm pivot point. At full extension my angle increases to beyond 100 degrees. Is that not the principle of rising rate theory? As the shock compresses under load the resistance of the shock should increase due to the angle. Am I wrong here? Please lay some of your wisdom my way, I am always seeking new knowledge!
