Come here to chat n ask questions about friction drives rather than making all little threads.
Well i have a Ryobi Scorpion King 30cc Weed Eater and ive got a Friction drive. Ive been experimenting with friction drives, i first started with a knurled 3cm diameter aluminum pole 10cm long, dont make the same mistake i did, the knurling wears out quick, a Steal knurled drive is the best. Ive found 3cm is the best Diameter, if u make it 4cm the motor has to work to hard and its not good for it, 3cm will give u a speed of about 25-30mph and decent hill climbs.
Ive tried rubber and its ok but steel is better, i stuck a rubber tube over my spindle and it was ok but it wears out quick, i mean rubber is a little quieter but wears out within a month so steel is ur best option.
Ive also tried heat shrink on my spindle but it ripped in about the first 2mins. If you started with some other soft metal the best thing to do is get a tube of JB Weld and mix it with a little sand, only a little, you dont want to sandpaper ur tire, just enough to add a lil more grip. Smear that over ur spindle and let it sit for about 24 hours and ull be cookin with gas.
Dont bother using something like skateboard wheels or other rubber or plastic spindles because they wear out real quick, they will give good grip but steal is still ur best option. I made mine on the lathe and it only took about 20mins, i made it from alu so ive since covered mine in JB Weld and sand.
If your thinking about getting a spindle drive this is some Pros and Cons.
Pros:
Easy to install and take off
Quiet
Easy
Cons:
Slips on Sand, wet ground and other things which then puts flat spots on ur spindle
A little tire wear but u should be able to get about 300 Miles on a tire or more with the right tire pressure and spindle.
So thats basically all. If you have any questions about spindle drives post them here or even if u just want to chat or post ur knowledge about them this is where to go.
Cheers,
