[@michelaylwin105]

A big Thank You for showing how to mount part. I just bought a Qeenbee Pro and ready to mount. Your video help me a lot Thnks

[@TimPercyKayakFishing]

Thanks for the videos. I'm presently running a Lead1515 machine, but I'm looking to update it a QueenBee Pro, unfortunately shipping prices to Canada right now are crazy.

[@willar25]

I am assembling my queen bee pro but a linear bearing doesnt move easily, any suggestions?

[@ToddBrownVA]

Can you describe what the base table you used is like? Is it perfectly flat?

[@IllDoItMyself]

Hey Todd. It's not perfect but I have a plywood base with mdf on top. My whole table folds up to the wall so I bolt my machine to the table.

Why flex coupler?

[@kenbouchard834]

After over a year of having my machine built I actually came back to this video to ask this very question! The flex coupler has invariably induced “flex” on my entire z axis. I had nothing but troubles trying to figure out why I couldn’t mill a simple pocket without have the bottom surface outrageously inconsistent. After all this time I finally figured out that when the bristles of my dust shoe made contact with the material surface it was putting upward pressure on the z-axis and the flex coupler “flexed” and I couldn’t get consistent cuts no matter what. Now I’m trying to figure out whether swapping for a rigid coupler would be safe to do, or whether the flex coupler was necessary for anything?
