Scored at the motorcycle swap meet today, new swing arm is about 2" wider than the first one giving me more room for chain and disc brake, not to mention a fatter tire and taller...HPIM5789.JPGHPIM5790.JPGHPIM5791.JPG:D:clapping:

Having problems with the rim, sooooo! picked up this one on the cheap with sprocket and disc mounted, mock the chain and then change the tire...HPIM5838.jpgandHPIM5839.jpg:clapping:

HPIM5843.jpgHPIM5844.JPGHPIM5845.JPGOK back to the drawing board, this tire (215-35-18) fits so good OMG! I will go with the first swing arm, set center then to tack weld with the lower control arms next:clapping:

Tire fits close for chain install.HPIM5861.JPGDamn nice fit, HPIM5857.JPGThis is so square it reminds me of my brother, ready for the welding...

Going to the machine shop and picking up the rear axle and lower control arm brackets for a little welding this morning. Check out the chain clearance, Ordered the button head bolts for the sprocket (need clearance) and the rod ends 7/16-20 for the coil over push rod...HPIM5854.JPGButton Head Torx 7-16 bolts.jpgRod Ends 7-16 x 20.jpg

More mock up, tack welded swing arm brackets to frame and lower control arm brackets.

More mocking on the upper frame rails and control arm brackets and those 18 degree vertical braces...HPIM5872.jpgHPIM5873.jpg

Thank You, I look at that single rear tire as we would a trike with 2 tires, 2 6" wide tires on the ground equal 12" of traction, You/We know there will be a time or two when we have to SLAM on the brakes and pray we stop short of the problem, damn I hate saying that...

The control arm lower brackets, tabs and gussets are 3/16, I hope overkill? I should have made some fixture bushings .005-.010 over and bolted before welding, I will for the upper ones...RT Control Arm brackets.JPG

what i do is put one or two pc of manila folder in there then u dont have to fart around w making bushings... with that setup i bet it will pull enough to get the a arm back in.... if it werent for the rubber i would weld it up solid as is yes a tad overkill.... my moto.... build it strong

u wont go wrong.... unless u are racing then u have to draw the line some place

Upper frame rails are being dialed in for jack shaft and engine clearance...

This is going to take some time and many headaches? Back to flatness problems again with 60 degree bends or cuts? Ordered a flat 46T Harley painted sprocket, I will counter sink the mounting bolts for a closer fit to the swing arm. Tomorrow is Thanksgiving holiday weekend and wife is out of the country with relatives SOOOOOOO!!! Home alone and many drawings and glasses of red wine, HPIM4010.JPGHPIM4012.jpgHPIM4015.JPG1-Happy Thanksgiving.jpgME2

Need to bend the upper frame rails out (left and right) so I'll have at least 16" on the inside, the engine is 15" wide, and again fittings of jack shaft and gear shift, exhaust mounting, so many things to consider. New sprocket and mounting bolts should be here soon...

Time to do some mock up on the jack shaft diameter or how many teeth per diameter? Or remember that big pot hole that almost bottomed out the car, I think a 4" would ease my mind now to figure the teeth for a 530 chain (Harley) 2.75 dia. sprocket = 16T, so I am GUESSING about 25T and I'll try to use the same size engine sprocket. I have a 37T and it is 6". Wheel sprocket will be Harley 46T.HPIM4036.JPGHPIM4035.JPGNow the up and down travel is less at the swing arm mounting as the rear is greater...Edit, There is a site for sprocket diameter to the number of teeth, 530 chain, 20T = 4" and 15T = 3" this will really help out for my jack shaft...

HPIM4046.JPGYeaaa! eBay's snail mail is here, one day late, Harley sprocket 46T and flat head bolts for recessing to get a little closer to the swing arm side.

Dropped off at the machine shop for countersinking, This is why I bought a painted sprocket, did not want to cut up the chrome, so I'll just paint it the trike color RED, should be finished tomorrow then set up the wheel to swing arm and then back to the upper frame rails...

can't keep my eyes off that rear wheel!!! All, is looking good! :D
Yesss, I like it more and more, wait till I ask my wife if she wants to learn how to polish it? She'll be laughing at me for a week...

HPIM4050.JPGBack from the machine shop with the countersinking finished and trial fit,HPIM4054.JPGHPIM4051.jpgHPIM4053.JPGNow I have 3/8 (.375) side clearance form sprocket to swing arm plus 1/2 the sprocket is .150 so this gives me .525 for 1/2 the chain, which is about 1.000 wide total,:clapping: Measured the length for the axel spacers on each side, now to re-do the mounting bracket since the upper frame rail is going to be wider so that's next with the upper rails themselves widened, then to the jack shaft, more measurements tomorrow (Sunday) then off to my steel supplier for swing arm brackets 3/8 this time? and some tubing for the swing arm push rod and to figure the bell crank, :xzqxz:
 
I am just following this thread because it is interesting and I am learning new things and watching someone create what is in their mind. It is awesome.... I am not as knowledgeable as others here, but I do like to expand my mind and that is done daily here.Merry Xmas to All, and please enjoy your family and friends, oh and keep safe everyone.

HPIM4078.jpgThe color, I want a medium red shade that can be seen from a distance.

Working on the paint for the swing arm now, and yes I remember the caliper bracket weld on, but later. I have to rely on rattle can for now...

HPIM4093.jpgHPIM4094.jpgHPIM4095.jpgHmmmmm!!! Maybe orange?

Do you think a red chain might be too much? heeheehee Tomorrow is off to the machine shop for more little pieces of the frame to swing arm and the changing of the rear frame width rails.

Machined the axle spacers and paint, HPIM4101.JPGNOT happy with the coil overs location...HPIM4104.jpgThe push rod is a pull rod? BACK TO THE DRAWING BOARD...

Damn I hate doing things wrong, That's what I get for NOT being an engineer, (re-work)HPIM4111.JPGThis should work?

yup that is the right direction one problem i might see is the swing arm where the wheel is attached much longer than the arm where the shock is mounted you need a short through super strong spring...but being light you might be okay the other potential issue the short travel on the connecting rod is so short it will may change the realized spring rate hope that makes sense it would help if you rotate the arm clockwise by moving the pivot to the front an lengthening the tie rod

RT coil over shock mock up.JPGAnother view, OK drawings are made and tomorrow is time to buy material and visit the machine shop...
