I built the full size frame using the 8 ft by 10 ft lumber
I put fold out steps so I can reach the top two anchor points.
I made some knurled handles for 3/8 nuts to be able to put the anchor points on easier than the wing nuts. I also put nails in the frame to hold the nuts near where I need to set them for easy access
I built a reinforced vacuum adapter for the rigid inch and 7/8 hose
I put a hanger with a chain that hangs out of the way and allows me to put the top two straps on without holding the Maslow sled up
I put a 20 ft cord rated for 20 amps on it with a 20 amp switch and two 15 amp outlets to plug in the router and sled behind the board and the vacuum off to the side, I added two hooks to hold the cord and made some cable tie mounts
I made a plaque for switch identification and the size of the frame so I didn’t have to remember that
My spoil board is just 7/16 OSB two sheets stacked on top of each other was a lot cheaper than plywood, and I can easily replace just the top board if necessary I hope to go easy on it.
Cheers
