I will fill this out with some diagrams

5/8" shaft comes into the first bevel gear

Meshes with second bevel gear on jackshaft

That way you can run an engine sideways up front in your little race car

Have a nice day

Bob

5/8" shaft is the driveshaft from engine up front to jackshaft box in back for rear axle

Are you trying to design something for a project your working on ? You may want to adapt a commercially available unit instead of making 1 yourself . The cost to machine your gears is going to be very expensive and complicated to set up just rite. Ive seen a right angle gearbox used in several builds on the cars and cameras youtube channel. They refer to it as a magic box. I have also seen units used on jacobsen garden tractors built in the 70's and early 80's.

The "magic box" used by the guys on Cars and Cameras is a gearbox from a tractor bush hog or a finishing mower. It takes the PTO shaft and turns 90 degrees down to spin a blade or a pulley to drive multiple blades.

Will add part about using Azusa 4 lug hubs for front and back

That gets you into the golf cart and trailer wheels and tires

Then a 4x8 rectangle frame out of 2" square tubing ought to get the project going

It can be regular rear engine cart engine set up just to get it rolling and done

Key is to use just kart parts and trailer,golf cart parts

Then make friends with local fabrication shop :)

Use light gauge steel and 1/8" plate

If you need more than that then the design needs a little redoing

Have a nice day

4x8 frame from 2x2 square tubing and 1/8 inch plate will be extremely heavy. Add the bevel gear driveline, which will be prohibitively expensive, and you have a heavy, expensive, underpowered project. Bevel gears are cute, but they need a solid housing, bearings and lubrication to work.
Making friends with the local machine shop will be even more expensive than buying your own tools to make parts.

Hi Sparkwizard

'need a solid housing, bearings and lubrication to work '

I believe the bearing plates Azusa uses for jackshafts will work

One at each end of driveshaft

Mount those to 1/8" plate and use 1" square to build up to where they need to be

2" square probably does not come in 16 gauge They might move you up to 1/8" wall

I am not too concerned about a lot of power

Just plunking around about 25 or 30 miles an hour will keep me amused

The fun is building it and seeing how it works out

Have a good week

Bob
