I sent you an email last Wednesday with the measurements I needed and never heard back from you.
Let's try this one more time...
Measure your 5/8" toolrest from TOP to BOTTOM
Measure your 1" toolrest from TOP to BOTTOM
That's it, just those two measurements.
Here is a photo of how I want you to measure your toolrests...
This is my toolrest from my Jet 1642, you can see in the photo from TOP to BOTTOM this rest is 6 1/4".
Now measure both of yours and get back to me.
