My name is Gabe and I'm new to the forum, this is my first post so here it is. I'm building a mini chopper on the cheap and homemade but i have access to lots of metal and drives so I don't have to sacrifice much so what types of drives are there other than torque converters, pulley and sprocket (centrifugal) and two speed jackshafts? Also I had recently purchased an old drill press and noticed the drive system which is stacked pulleys from big to small like the rear sprocket on a mountain bike and an exact opposite on the drive side (small to big. Has anyone tried a drive system like this either with the mountain bike sprockets or multi pulleys.forgot to mention on the drill pres you move the belt manually up and down on the different sets of pulleys to get different gear ratios and also I have an adjustable pulley that you adjust how close the pulley wall is to determine where on the pulley the belt with ride by screwing the outside wall left or right and locking with a set screw I will try and get pics up in a bit. Reason I'm asking is because I don't wanna spend any more money and wanna work with what I have
Different types of drives?

Basic drive options:
-Centrifugal clutch, either chain or belt
-CVT (aka torque converter, w/ chain final drive
-Manually-operated belt-tensioner style clutch w/ jackshaft and belt or chain final
These are the basics. If you have the skills/tools you can examine funky multi-speed belt drives. The "stacked" pulleys could probably be done with some work, but so far, I have only seen cheap cast zinc or aluminum versions of these pulleys with bores that are too small for our purposes. For that matter, they tend to use belts that are too small.
A note on jackshafts- Jackshafts are used for one or more of the following reasons: 1)To allow compound gear reduction 2)With CVT's that are not self-contained 3)To change drive sides from left to right 4)To change drive systems from chain to belt or vise-versa. 5) To align a drive pulley with swingarm pivots to allow suspension. There are other potential reasons to run a jackshaft, these are just the more common reasons.
