I thought of including prices when I was creating the booklet but decided not to. Prices change with time and economic situations. In order to keep my booklet accurate, I would need to update it monthly. In addition, all of my designs are junkyard and salvage yard friendly.

If one were to purchase a 7½ HP 3-phace motor new, it would cost more than $1,000. I got the one shown in the booklet for $10. It would be misleading to publish either price as the gold standard.

I got the pony motor for free when my FHA furnace crapped out and I had to get a replacement. The pony motor started its life as a hot air blower motor.

All the steel used in the design was surplus from other projects. My cost for the converter was in the neighborhood of $50 including fasteners and shop electricity & heat.

.... I'm just saying ....

The BOM is on page 9 by the way.
