I'm building up a 9in for my project, a 140in slingshot. It's the big bearing 3.150 ends. In order to get to the proper case width and then determin shaft lengths I need to confirm some measurements,

Brake Offset is 2.5in correct ? is this measured case flange face to shaft flange face or back ?
Distance between shafts should be 1 1/8in correct ?
One shaft (left) will be 3in shorter / longer than the other correct ?

Currently it looks as though the case will be 27.618in and the axles flange to flange 32.618in

On that basis I've calcualted the axles to be 15.685 and 12.685in respectivley. Anyone got a formula to confirm this ?

Thanks

Phil

According to the Mark Williams website, you're correct on the standout. It's 2.5", and it's measured from the bearing seat to the face of the axle flange. Mark's website has some tech pages that have all this info, and some illustrations to show it as well. Check it out and I'm sure it will help you with your measurements.

Phil, when it came time to get axles for my Beretta I just called them and they asked the questions...Now I used Strange but if I remember correctly they just asked: Housing width,type of flange,and who's brakes I was using,and who's spool.

Axles came and everything fit \:D/

Phil, try this site also. Most of this is dealing with door cars but some of the figures there will also apply to your slingshot. Google search probably has more of this kind of stuff as well.

What we need to keep in mind here is that Phil is one of our friends over in England and it's much harder doing things from "across the pond" than it is here. ;-) I dare say that if we had to go though as much crap as those guys do just to race, many of us WOULDN'T!

thanks guys, we're getting there with it, all the info is really appreciated.

Ken, you're spot on, sometimes the sourcing of parts etc makes it real difficult to put a decent car together. Theres plenty of parts second hand but most of it's trash or overpriced. The weak pound and rising cost of shipping is a killer too. For an order from Jegs the bulkiest bits being rear tyres, was free shiiping in the lower 48....but over $1500 to ship internationally..killer, but we're getting there, frames almost done, motor and trans already built. Next up will be the hand beaten aluminium chute packer body, I'll get some pics up when I can.
