Project "Low Brow"
« on: October 25, 2009, 11:46:12 AM »
not really the name of the bike , more a theme to the build .... i'm thinking , tough looking ... i want people to see it and instantly know it get ridden alot ...  i'm thinking "bobber inspired cafe 2 seater"  

i won't be doing any animal print (really sick of all my friends askin that) .. most of the details are still up in the air
but here is whats gonna happen for sure

130x16" rear wheel  
white walls
hand made metal side covers
polished top tree
either satin, or low gloss black frame
some sort of dark blue satin tank and side covers  
drag bars
twin front brakes w/drilled rotors
vented rear hub
650 cam (if i can find one)
light porting (just smooth out the passages, not really remove any meat)

but main thing for this build is to take as many stock parts and turn them into something else
like the tail being a stock fender all cut up ... and so on

.... i like to let the pics do the talkin  soooo...



this is what happens when you don't prep good before you do a tank liner

this tank was REALLY dented up and had alot of bondo ....ALOT ... i was trying to cut off as much as i could, but in the end i had a lil hammering to do to get it straight

when using sheet metal , alway make templates first

make sure you mark them

don't forget to mark the pieces too

stop and check, stop and check, stop and check, stop and check, ... metal can be pretty unforgiving sometimes


on to the tail

support bracket removed

a chunk of stock rear fender welded on , and hammered to accept the seat

round bar i had layin around



a lil somthin like this 


more later .... see ya

   so i ran out of bondo long ago ... but i still have alot of spot putty... and tons of J.B. weld  sooooo

i'm filling the holes with JB weld and then finishing it all off with spot putty ... not the best way to do it ... but affective none the less  ;D ;D ;D

Cool!   I like the theme! 

Tell me more about welding on the tank panels.  Is it tricky?

as far as welding sheet goes .. just take your time , stop and take a step back and look at it ALOT  (like, after every tack) 

mine was done with a MIG running flux core wire ... NEVER EVER EVER EVER again will i do this without a tig welder (lost my job, so i don't have access to one anymore)

it's totally do-able ,  just plan on it taking FOREVER

Having a lil helper is the best. I was one and my brother and I are working on cars and bikes together to this day. I still remember every trip to the junkyard and racetrack. My lil helpers are girls. One drives my dragster now and goes zero to 180 in 7.5 seconds. She's way better on the starting line than me and most people I know.
 The bike looks good keep it going.

I was stuck on these two pics for bit wondering what you were doing.  It finally came to me.  Your hand is inside the tank - you cut the sides of the tank out.  Kewl.

Tank looks great!

What did you cut it with?

Can't you run gas in your MIG?  Way less painful than fluxcore imho.

You are a wizard with metal that's for sure.  I tip my virtual hat to you.

BTW, JB Weld has gotta be the world's most expensive body filler, but it'll never shrink or fall off lol!  :)

attach the seat to a pan with hinges or welded-in bolts and stick the pan to the bike?

Seat pan idea...  Make the pan out of metal, let the four "corners" extend out the sides and wrap around the frame rails like spring clips. 

benefit...no protruding hinge or latch hardware

Really like the seat idea - a 2-up cafe-style seat is something I'd like to figure out, eventually.  Keep up the good work.

thats what i did for my seat on the Phoenix i used the bolts as pegs (check the "before the fire" thread in my sig), .. but for this i need the rear to be more secure , i've already made the pan, thats a no brainer. attaching it securely in the front and rear with everything hidden . is gonna be a little bit of a pain

i was thinking maybe bolts , with wingnuts from the bottom .. but .. that just seems kinda half assed

thats not his first time by far my man , he would come to my work with his mom, waiting for me to get off ..and chill at the end of my table with an auto shield on just watching , he just started actually welding about 5 or 6 months ago (right around his 5th b'day) .. he can do lil 1/4" beads (they're so f'n cute, cracks me up) soon enough he'll be buildin some crazy #$%*  ;D  you should see some of his lego creations  ;)
