I measured the front to back occilation on my blade when running. Depending on the motor mount rotation, I see 

a minimum of .015, to a maximum of .045. The saw runs very well, but I am wondering if these back and forth occilations 

are in proper limits.

I replaced the Jet clamps with Pegas clamps, both upper and lower, but neglected to measure the occilation with the Jet clamps.

Have any of you done similar measurements? I could not find references to occilations in the search bar.

You might be able to get it closer to a straight up down by removing the bolts in the slots and moving the motor to the next set of slots. I had to do this 2 times on my Excalibur before i could really get it dialed in.. and doing so made the saw a whole lot more quieter and smoother running too.

The Jet motor has 3 mounting bolts with elongated mounting holes, I had not thought about

actually removing the bolts and rotating the motor an entire 1/3, I will have to try that. 

The Pegas clamps are very simple to install, it took maybe 15 minutes to remove the Jet clamps and

install both new Pegas clamps. It is a nice upgrade if you can swallow the price. The original upper clamp was

jamming almost from new, and the lower clamp (spring claw retainer) was not great either. The Pegas clamps

are easy to use, and have good holding power. They ooze quality, even the packaging is a class act.

First thing first when tuning these saws.. so first make sure the upper arm is the same distance from the table top of the saw at both front and rear positions.. Adjust it by turning the knob on top of the saw at the rear of the saw. Once it's completely parallel to the table top is when you start adjusting the motor slots. I keep a block of wood just the right size that just fits under the upper arm between the arm and table top so I can easily check to be sure the arm is still parallel. As these saws get older that knob at the back likes to start turning on it's own and will need readjusted periodically. Having that block of wood handy makes for quick checking and adjusting.
