The spacing is 182mm by 45mm, I just maintained the stock offset, as I liked the way the bike handled, going shorter/longer would be no problem, I considered maybe going 40mm but just decided to maintain stock rake/trail.
There are internet sources that say that the CB550 (1974) is 180, but it is in fact 182mm for factory specs.

I actually machined little shelves from the backside, and used stainless steel screen.
Hysol epoxy is really great stuff, and resists heat and chemicals like a champ, not to mention that it is also extremely tough and adheres to aluminum super well. I degreased the screen and the drum with acetone, then applied a light layer to the shelf, set the screen in, then carefully gooped more Hysol over the edges. The Hysol will then settle and totally encapsulate the screen edges for a bombproof job. I have used Hysol for this type of application since the mid nineties without a single issue/failure. I really trust the Hysol as epoxies go.

Those are Chick vises, and that is one of my small CNC mills, I use my smaller ones for my side projects.
I started out with a Bridgeport, and made really complex stuff, some operations were done with a belt sander etc. so with some elbow grease and some planning, you can make incredible stuff with just a manual Bridgeport.

Hit the deck... 'cause this guy is blowing my mind! 
Nicest, cleanest work around. It is almost out of place with all the mad scientists we have on DTT. The P38 isn't government funded is it. If your a spook I don't want to know. Forget I asked... ;D

here is the deal, it seems like as has been said and by my own reckoning of looking at the triple trees, this bike is gonna end up siko!!!!
trouble is i also have a cb550 its a 76 but i think the measurements are the same. so i am 6'1" and have been called everything from spindly to fast and also just skinny, this is important to you, in keeping my demintions in mind while fabricating, especially if you make clip-ons to match the trees and rear sets to fit the passenger peg spots.
just pm me when they are all done and ill send you the cash to ship all the copies of your metalwork to 28401.
long post short
"lookin good!!!!!"
also i would like to know where you got that screen i want to use something like that in my custom v stacks

Different angles, made the top nut and the steerer out of 17-4 stainless steel.
Here are the stainless fork stops, a must have on a street bike unless you want your tank to act as a stop..........
New fork tubes from "Frank's Super Fork Emporium" AKA "Frank Forks" as my old ones were rusty, and had a deep scratch located right at the seal.

I work 12-16 hours a day, and my company is 7 months behind on orders of what we make normally, this stuff is a late night labor of love with many Red Bulls mixed in, I wouldn't consider producing this stuff in any quantity, this is just one-off goods to get rid of stress.
Sorry-

Thank you-
What inspires me, is that you younger guys and gals are actually building stuff with your own two hands, you people are so far ahead of the game, believe me. I have seen incredible work being done with no money and extremely limited resources, and this site is a great place to showcase these skills. I ALWAYS respect skill and dedication.

wow.. I need access to a cnc mill
This project is really looking great. I need to look into getting some new fork tubes, those things are tits.

The tubes ran $271.00 (shipped) and they are an instock item, unless they whipped a set up overnight. I received the new tubes within 4 days.
Google "Forking by Frank" (actual business name) or "Franks Forks" all roads lead to Rome there. They are lathe turned and hard-chromed, so the surface finish is a tad different from stock tubes that are absolutely smooth. Stock tubes are ground, the tubes I got were not. I have dealt with this company a long time ago, and cannot recall if the tubes were ground or not-

Here are the clip-ons (not polished yet!) and I machined them at 5 degrees, I usually machine them at 7-9, but 5 degrees is easier on the wrists for road trips IMO.
The stock brake lever/master cylinder assembly is way too long for the way I want to build the bike though, the bars would have to be nearly 16 inches to accomodate the throttle and the super long brake assembly. I am now looking for a "shorter" master cylinder assembly, probably with a remote reservoir so I can keep the bars narrow.
