1972 CB450 brat-style

After bodyfiller was smoothed out I hung stuff on my mobile rack I built from black-iron pipe and parts of an old hand-trunk my neighbor left on the curb. The rack adjusts up and down and can be taken apart for so store in less space when not in use

I'm using paint from thecoatingstore. First I sprayed everything with epoxy primer and then hit it with single-stage (no need for clear coat) black

After the paint was dry I realized I was tantalizingly close to being able to assemble the bike at least into a roller and fire it up. But first I could not resist laying all parts out for a "some-assembly-required" photo:

Now were in mid May 2015 and I'm about to start assembly, but I needed to run the controls wires through the Renthal bars I would be used

May 2015 Assembly Time ! Laid the engine on its side and draped the much lighter frame over it (love that trick!)

2015-05-01%2017.25.21_zpsumhxvqtg.jpg


Tipped it up and started bolting on various bits and pieces

Starting to look a bit like a motorcycle again. The poster-board indicates I am not happy with my custom headlight brackets and wish I'd made them so the headlight sits lower.

It was around this time I fired up the engine and she ran great. There's a video on youtube, but I'll not post the link because I sound like such a doofus in it. Feel free to search for it if you dare...
 
By the end of May 2015 I had decided the stamped passenger peg / muffler brackets needed a little bling so I made some little plates of polished aluminum and riveted them on

From the same day here's a close-up of the battery-box area and the main power and ground cables. If you peek closely you can see the Kolher lawn tractor rectifier/regulator bolted to the bottom of the battery-box. If only there was some cool way to clean-up the top of the battery-box . . . . . .

By mid-June I had used my $200 Brother sewing machine, some 1/2-inch foam and marine vinyl to make a little cover that fits over the top of the battery-box to hide the battery, wires, and fuses. The "skirt" of the cover has elastic and the front has hook/loop straps to help keep the cover from going anywhere.

I even made and sewed on piping and did a little "french seam" on the back. It is so cool how you can pretty much learn to do anything via youtube videos

June 2015 and I'm working on the seat. I cut some foam from HF floor mats and an old pool float used DAP Weldwood contact cement to glue them to the aluminum seat pan

179_zpsong7y3ta.jpg


Then I made a sandwich of marine vinyl, 1/2-inch foam, and cotton stuck together with temporary fabric adhesive. I marked out lines for my pleats using a Stabilo pencil and sewed them using white thread on the $200 Brother machine. I also made some piping by wrapping 3/16-inch cording inside strips of the vinyl sewed together on the bias

180_zpslhu1cv7w.jpg


This was my first ever attempt at making and covering a cycle seat and I was really happy with how it turned out

197_zpszqka2qpy.jpg


I did a french seam at the back

198_zpstigevhmj.jpg


And riveted it to through holes drilled around the perimeter of the aluminum pan. I had to make a bunch of large "washers" out of 22ga to prevent the vinyl from tearing around the rivet. Finally I used contact cement to glue a piece of black felt to cover of the rivets and give it a nice finished look

Late June 2015 and a major setback This was the third engine I'd completely rebuilt since 2012 and all had fired right up and ran great which was nice. But this one now had a major transmission issue -- it was very hard to shift and could easily get to a point where the transmission was all but locked up. Apparently I had not benched tested shifting through all the gears as I should have and had done on the previous engines. I pulled the clutch cover and messed around and inspected the shift drum and linkage over and over hoping there would be some way to fix it without having to pull the engine. But alas no. So out came the engine from the freshly painted frame

206_zps6qvoflxv.jpg


And the case were split

207_zpsutvujoag.jpg


It turned out that the shift fork closest to the case wall was bent by less than 1mm, but that was just enough to cause the fork to lock up hard against the case wall. So I bought an entire used CB450 transmission via ebay and cherry-picked the best parts from that and the original one. I'm happy to say after it was all back together it was shifting like new.
 
So the engine was back together and back in the frame and nothing much happened for a couple of months. All that was left was the painting of the tank, fenders and a few other parts and bike would be done. Below is a pic of the bike on 28 August 2015 (my 55th birthday.) She is out in the sun for the first time on her new tires. She is heading from the hot garage to the shiny new workshop around the back of the house. I had no idea then, but it would be 9 months before she'd get worked on again...

So 9 months went by during which time I was setting up the new shop. I used a french cleat system to make it easy to hang stuff on the walls and that took a while to set up (and lots of 1x4s) but it was well worth it. Nothing is bolted to the wall except the cleats. Then you just use scrap wood to make hangers for tools, etc. If you don't like where something is you simply yank it upward to unhook it from the cleat on the wall and move it somewhere else. I also had to figure out a paint booth with fresh air in and overspray laden air out (via paint arrestor pads, of course) and some kind of curtain. All this took a while to set up. But it was well worth it.

It is now early June 2016 and the next Jax Beach Vintage Moto night is barely 4 weeks away (last Wednesday of the month.) And I was determined to debut the CB450 there. So work resumed with bodywork and playing around with paint scheme ideas

Epoxy primer to seal up the metal

605_zpscb6hips8.jpg
 
By 12 June 2016 bodywork is done and I'm laying on House of Kolor KD3000 primer/sealer. This stuff is amazing! You can use it as high-build, medium-build, or as a sealer and it lays down like silk -- highly recommended!

I had a beat-up 3/4 helmet that I decided I would paint to compliment the bike

14 June 2016 a little wet-sanding with 400 ...

633_zpszvhfj8dm.jpg


... then time to lay down the charcoal metallic and mask off for some silver metallic stripes

634_zpsjipnrzhr.jpg


If you look closely you can see where I ran the charcoal metallic -- shit!
 
16 June 2016 working on the helmet and trying to pretend I'm a custom painter that knows how to use an air-brush

650_zpsz2fwq78t.jpg


Didn't turn out too bad, actually

654_zps7hmqxssq.jpg
 
Also mid-June 2016 I've rigged up the battery on blocks of wood since the battery box is yet to be painted and fired up the engine for the first time in 9 months

651_zpsoetqbchy.jpg
 
24 June 2016 tackling the battery box I again decide to pretend I have any business holding an air-brush and try to paint on a CB450 badge

741_zps6o7z8n75.jpg


Hey! Not too bad so far

742_zpsgtykcz3n.jpg


Oops! Got a little shakey and carried away with trying to free-hand highlights, but I'm hoping it will look OK from 5 + feet away

743_zpsnhwluto9.jpg
 
My Dad told me the best way to handle the tire-side of the fender with to spray on some rubberized undercoating. He was even nice enough to send me a rattle can of Eastwood brand that works beautifully

744_zpszvsyh3kn.jpg
 
26 June 2016 at the very last minute I realized the rusty original gas cap that I had sprayed VHT satin black many months before looks like shit compared to the rest of somewhat spiffy paint job. So just when I thought I was done painting, I had to paint one more part, but it was well worth it

749_zpsbkgkvumo.jpg
 
Finally assembly in process...

746_zpsqgkyzmun.jpg


Monday 27 June 2016 could it be? Am I really done ? With two whole days to spare for shake-out before the bike night on Wednesday -- woot!

750_zpskn8cvaje.jpg
 
27 June 2016 I rolled her out into the sun for a few glamour shots and to take some rides and do the usual adjustments and tuning. She runs very well and made her debut at the bike night two days later (we got rained on, but still had fun) and was well received which was very gratifying.
