I've seen pics of a motorized machine, that has a wooden box cover, that is a cresting machine. It's benefit is it compensates for slightly curved or out of round wooden shafts by using spring loaded rubber rollers......? Does anyone know where I can buy one of these? Has anyone used one and what can you tell me about it?  Thanks!

It's a Philips Cresting Machine.

Lost Nation Archery has them.

This is where I bought mine.  They are expensive, but very nice.  I just made a dozen with mine for  a benefit here in town.

Put an on/off switch on the cord if they haven't changed it - when mine came it was just a cord.  Also, I use mine with very little spring tension.  

I like the way the machine spins the shafts.  But I have noticed with some hickory arrows I had (which were not perfectly in the shape of a circle (diameter wise)) that they didn't want to spin all that well.  I suppose it's inherent to the design.  If you are spinnning the shaft from the middle, it's harder to spin an oval than a circle.

I'd buy one again
