Not much to report from the weekend
had mechanical problems with my person vehicle so focused working on that

I did however narrow down my choices on a sprocket / chainring
Duchess got me thinking
about maybe having the sprocket be the turbo/supercharger of the indy motor
since the offys and novi engines had forced induction

I also happen to have the smaller part (44t) of a murray x2 turbo gear sprocket


the chainring on the right is a smaller version (44t) of the chainring that was originally connected to the Murray turbo sprocket
So i will be using one of these two

below is the bike where the larger (52t) chainring was used

Hit some snags this last few weeks but I am back on track
first issue was I couldnt find an affordable spider to fit the uni directional chainring
almost went with the boring solid murray chainring
But found a disc that will work for now


Also had to straighten the frame so that has held me off from painting
but I did at least get some spray can pearl on the fender and guards



I didn't have enough so i need to put another coat on
but it has been unusually humid so the process is a lot slower
at least I didn't have to prep the metal too much
since I am going for a long lost indy car look
besides its a ratrod
it doesn't need to be too pretty

I haven't forgot about sharkruiser either
but I have hit just as many snags on that project also

I did trim the "Nostril" area


The one big problem i discovered was the stem I wanted to use was for a 1 1/8 fork
so i needed a new solution
ended up separating it in the middle
but I needed a new stem for the fork

I had two bmx styles in my stash
one was narrow enough but to tall
the other was too wide but low enough

Ended up with the middle one that i also found at the local bike swap meet

I didnt get nearly as many photos at the end of this build as I would have liked
The pearl mist spray paint ended up causing me to fall quite behind
to make the paint job work I had to use a lot less of the pearl and more of the metalcast cround coat silver

Which turned out to work well since I was also using the red anodizing color



The only two other progress shots I got was changing the seat springs
I wanted the rear spring to match the front spring and I had a hairpin base that fit one of my older seats
original spring base on the right


also wanted to show the #13 on the murray crank arm I used


I was also planing to use some model car decals on the bike but they didnt arrive in time
