The wife and I moved at the beginning of the year and i have been diligently busy setting up shop in the new garage. I moved closer to family, and was able to borrow a welder from a family member, so i decided to finally use some rollers I purchased years ago from someone on the creek. I really hate sheet goods going over the back and I didn't want to spend 300-400 bucks for the HTC/Grizzly Extension table. It took maybe 5-10 hours of work. I still need to clean/prime and paint it though, but that is the easy part. The difficult part was getting the frame of the extension to be below the rollers (1 3/8" diameter rollers mounted between 1" square tube, so 3/16" overhang on each side. Then getting it parallel and even with the tablesaw top. Right now it just supports on a piece of wood that sticks between to pieces of angle iron, one on the saw and one on the extension. But given time, I would like to make a locking/pivoting arm that will collapse and pivot in its middle, but lock when I want to set the table up.
I also was having unevenness/sagging in my old router extension wing, so I decided to weld a frame up for that, which I will then mount a few sheets of 3/4" MDF on top of and put the Jessem Mast-R-Lift in.
