Hi Jerry
 If you want to build a cog belt redrive I can make custom

pulleys.

 Check out my web site and you can see some of the pulleys that

I have made.

Ken, do you have prices on the different sizes
Namely a 3.11 ratio, and a  2.95.
Thanks
Royce

  The 2.95 and the 3.11 use a 118 tooth upper pulley made from
aluminum and the price on it is $900

How wide are these pulleys

  The 3.11 uses a 38 tooth lower and the 2,95 uses a 40 tooth and
they are made from 1045 steel and the cost is $400 for the lower ones.

What is the reason you use steel for the lower pulleys, and not

aluminum?

 For a lower horse power engine

How much power with this redrive handle?

the pulleys could be much smaller in
both diameter and width cutting the cost way down as the 60 pound

You start with a 60 lb block of aluminum? Wow.

chunk of aluminum that I make that 10 pound upper pulley from costs
me $350 and you wouldn't believe what 50 pounds of shavings looks
like.

Goodness Ken, isn't there a better, more efficient way of doing that?
We have looked at your web site, looks like you do a fine job on the
redrive.
How do you put the correct tension on the belt, an idler, or adjustable
upper pulley?

Royce there is something about your email program that puts a bunch
of >>>>>> in front of every line. Can you fix that?

An idea,
Ken, have you ever thought of using  two pieces off hollow aluminum  tubing,
a small one in the center to house the bearings, and
a larger one off witch  the cog is cut out.Two discs welded on either side
to supported the lot,not unlike a thick aluminum drum.

Or just cut the teeth in a chunk of large diameter thick wall tubing
instead of billet and weld in a hub.
