There are many SPI parts (or materials) that we don't buy them from SPI.

For instance, these things are VERY available to us:
Shoulder bolts
Delrin
Nylon washers
Oil Lite bearings/bushings

For making a FIRST robot, these parts are only available through SPI (except possibly the shoulder bolts, which I'm not sure about their fastener status).

Any of these parts that we get by "other means" are verified to be dimensionally and functionally the same as the SPI parts.

For instance: I just grabbed a bar of 1"x1" Delrin off our stock shelf yesterday to make some parts for a mechanism. Looking on page 140 of SPI, I see that we can buy 2" diameter Black Delrin from SPI. I'd be suprised if we have to use over 36", but worse case, our team's SPI cost will be accounted with $85.50 for the use of a few blocks of Delrin. We do this without buying any Delrin from SPI.

Once we use these parts, we still account for all of them on our SPI spreadsheet... just like we bought them.

We spend much $$ at SPI (well over $1,000), and I see it being silly for some of duality of buying things from them that we have readily available to us. We are confident that these parts and/or materials are the same that we would get from SPI.

If we're out of line here, please let me know.
