Gotta make us some DIY swing arm bushings

First a quick cleanin' of the bushin' holder(s)

Then stuck a section of some Hi-Performance 1/2" rubber fuel hose (the kool red kind)
...thru the bushin' holder

* Fits in the bushin' holder quite nicely

Nice-n-clean trimmin'

Kinda like this

Then, inserted a section of 1/2" steel tube

Like this

After trimmin'
...looked like this

* Seems ta be a "right pro-fessional lookin' (3/8" ID x 1" OD x 3" long) bushin"...if I do say so myself

Next, we needed some swing arm mounting brackets

* Just a piece of 1/8" x 1" steel
...bent in ta a U-shaped bracket
...with a nice-n-flat area for boltin' to the racer

QC inspector Ducky watchin' a test fit

Theys look & mount, ta the trailing arm/bushings about like this

I'm kinda leary about just drillin' a bunch of holes in the FG monocoque...just yet
...so, I'ma gonna do most of the aligning on the "hump" of the mold

Another view

I noticed a couple of issues:

1.) There needs ta be more clearance on (1) side of the wheel, due to the sprocket
...so, the swing arm needs ta be off set to keep the wheel in the middle of the racer

2.) The swing arm may be a bit too long ta "fit" under/inside of the rear of the monocoque

 

[Functional Artist]

Made sure the "hump" wasa level

Then, made sure the swing arm wasa level
...& at the proper height

Then, established the center of the monocoque

Used a string, to "project" the center line down & across the rear wheel

Kinda like this

* Notice the offset?

Workin' on gettin' the swing arm mounting brackets mounted

Aligned & (temp) mounted with (1) screw (on each side)

* Notice the indicator markings, on each bracket
...& the corresponding marks on the backin' plate?

They are to help maintain the orientation
...& so, the brackets don't get "mixed up" (left & right)

Then, test fit the swing arm
...just ta be sure

After double checkin'
...I installed the other screw
...'cause "this is where they gonna be"

I love the homemade bushing idea!

I love the homemade bushing idea!

Thanks...my friend

Seems better & a bit more professional than just a bolt thru a coupla steel holes
...& the rubber insert, even gives the "junction" a bit of a cushion-ing-effect

Flipped 'er over for a quick looksie

Another view

* Anyone notice the suspension pad
...is suspendin' the racer

I must admit thats the coolest wheelbarrow jacuzzi I've ever seen.


Looking good

You def make the best use of your time. Coming along great, looking forward to seeing this idea you have completed.
