Emil has recently purchased a bunch of parts to modernise his billy cart – and now it’s certainly back to the future!
The billy cart is virtually completed and almost ready for a test rum. Just need the 40wheel spacers which are on the way and two brake cables which I will have on Thursday.
My current billycart which I am very happy with has evolved from – see below.
Thank you for all your help. I will certainly tell anyone who wants to know where I got my parts from
1978
Steering Wheel and ROPE
• Hand brake on RHS pneumatic tyre
• My Son Peter is pilot
1979
Steering Wheel and Tie rods
• Hand brake on RHS pneumatic tyre. Clocked at 50 km/hr – I was younger and less wise!
• Now I just have less hair
2019
Go Kart steering and wheel components
• Hand brake on both rear bicycle pneumatic tyre wheel rim. Awaiting, for cables to get delivered!
• Lower end of steering column fitted with a ball bearing
Go Kart steering and wheel components
• Toe-in not yet adjusted
Apart from a few coats of paint, my billycart is all done. I have had 5 test runs and so far highest speed attained is 47.2 km/hr. This more to do with me applying brakes to ensure that bumper bar not tested by kerb at end of road than maximum speed cart will do. ????????????
During that run:
• Toe-in = 1-2 degrees
• Caster = 3-4 degrees
• Camber = 3 degrees
• Tie rods moved to slot which gives LEAST front wheels turn for a given steering wheel rotation. Lock2lock = 96 degrees and INSIDE wheel turn = 18 degrees
• GPS Speedo mounted on steering wheel
• Dash-cam camera mounted top of rear wing on driver LHS
• Steering damper not in place. Damper selected from steering dampers available for motor bikes and is adjustable for damping level – Soft to Hard
Bench testing of steering damper suggest that it should all but eliminate wobbles
• Planning to do many test runs this week-end
Installing bicycle disk brakes on front go kart wheels has proven to be a bit of a nightmare!
But they work very nicely.
The process of machining and fitting all the parts which I could not purchase required wheels off and back on many times. This has meant that nyloc wheel nuts are now not so effective and I will be replacing them with new ones shortly.
Holes in front brake pedal are to reduce DRAG.
