SELF INTRODUCTION: My name is Dan, i'm 28 years old and i live in Ontario Canada. i grew up in an old school house that my dad fixed up out in the country, just outside a very small town called Hillsdale. i spent most of my childhood working at the farm up the road, so i guess you could say im a country boy. school and me never quite saw eye to eye, not that i wasn't smart enough, but i had a big issue with authority, so i ended up dropping out of highschool to start working in construction. spent about 6 years as a general contractor, but most of the work was in Toronto and i got tired of commuting. now i'm a heavy equipment operator, i spend my summers diggin holes, and my winters plowing snow. i do everything from floating equipment and driving truck, to digging basements and installing septics. I also do quite a bit of maintinence and repairs on our trucks and equipment. thats where i learned to weld (mig & stick) as well as basic mechanical and fabrication skills. i've been with this company for 6 years now. i've been married 7 years now, and we have 2 boys 10 and 12 yrs old. i spend as much of my spare time out on the bike as possible. im riding a F model VTX1800, i try to get away on at least one long trip every year. last couple years me and the guys have rode to north carolina, i love those mountain roads. I've allways dreamed of building a bike, but never thought it was actually a possibility untill i found the CBH website. i read through the OSC build and it completely blew me away, i then read through every article on the site and now i'm a huge fan. everything from the attitude and idea, to the work thats done is fantastic. i'm starting my first bike build real soon, ive got my bender die ordered from jd2 and i've started building the CBH bender. even just skimming through this message board provides more usefull tech knowlege about choppers than the entire web. now im chasing a dream, thanks CBH.

Oh it is indeed important, in that it takes away a lot of floor space.. :mrgreen:
However the legs and the rails are bolted togheter, so that I can dismantle and put it out of the way ;)
Unfortunately my bender didn't came out as nicely.. :sad: I'll post some pictures soon... :whistle:

SELF INTRODUCTION: Intereseted in all thing motorcycling, particularly modifications folk do to their bikes. Admire quality design and workmanship. Not so keen on bolt-on parts, but they have their place in the world. Not everyone can be a master machinist, welder or spray painter, but that won't stop me from trying. Great admirer of master engravers and have been working hard for several years to improve my skills in this most difficult of crafts. Also enjoy pin striping, and am fairly good at it.

Shouldn't the axle plate locating pins be removable so you can get the frame off the jig after it's welded?

He might have tapped the ends......but unless he has multible rear axle fixtures, all the frames will have the same width tire...I see multi holes on the frame rail fixture ! Just trying to give the newb's something to think about....

The truth is that this is an extremely peculiar, almost unique, disposable dumbass axle plates holder; you can quite easily fabricate one of these if you just start welding random pieces after a good bottle of Brunello di Montalcino.. :roll:
I posted the picture anyway, because I've not rebuild it yet... :mrgreen: I'll build my first frame and then cut it away...
Very economic, I know... :whistle:

that is one of the things about fixtures is they have parts that add on and off, nothing is in stone. fixture looks good.
