That's a very generous offer Seth. I have emailed you the list of those who have indicated they want pulleys.

As I have said before I am in the process of redeveloping the drive so the only fully built version of the drive on hand is one I built for someone. Funnily enough, he wants it. I have asked him whether I can hang on to it for another week, so as of next Friday I won't have access to a built drive.

This may make it more difficult to answer specific questions about the drive so I would ask everybody to get back to me with any questions ASAP.

I would like to purchase one controller board. Whether an extra or unwanted one from this run, or in a future run.

Thanks,
- Eric

Sorry, been away for a while, and not wanting to be the one to try and drive the platter from the motor's bare spindle, I will definitely be wanting a pulley. Do count me in.

I also recall being at one time on the waiting list for the controller kit, but the way things have panned out so far (the resistor shortfall, the coordinator's reluctance to do another run of the boards,etc), I wonder whether I will be getting any...

Seeing as they have already been delivered, should anyone want to dispose of theirs, for whatever reason, I am ready to take up their offer (just remember... "no PayPal please, we is in Africa...")

As someone who lives in a regional area of a small out of the way country I can appreciate your plight. I will email you and we'll see if we can work something out.

Default Pulley Order Wiki

I've added a page to the Group Buy Wiki:



Expect PayPal issues to be sorted through this weekend.

Expect a final delivered (in CONUS) price around $40.00. I'm still working on a decent option to ship to Europe.

The machinist informs me that delivery from him will happen in 3-4 weeks.

There will be an open book policy regarding cost accounting.

What belt width will this pulley accept? Sorry I don't know the precise term for the measurement I'm looking for, but I guess it would be the length of the cylinder's axis minus a bit for the larger diameter caps at each end of the pulley.

Default Pulley Dimensions

Frank at Promac advises:

Here are the main dimensions of the proposed pulley.
All dimensions are in inches. This pulley will work
with a mounting plate thickness up to 0.250" with a
10mm hole in it to accept the motor. If the plate is
thicker than 0.250, the pulley would not work.

Main body O.D. = 0.740(can be 0.700-0.750, not
critical)
Crowned area = 0.635 diameter
Crowned area is 0.320 wide. (0.250 wide belt.)
Overall length = 0.775
Distance from bottom of pulley to centerline of belt
0.540
