Built a vacuum seeder for ther grow room, this one fits the 1020 98 cell trays
2 pieces of ¼ inch masonite or plywood roughly 12” X24”
4 pieces of ½ or ¾ plywood or dimensional lumber
8 wood screws 1-5/8
Grove them out on the table saw starting at about 3/8” from the edges so your sheet goods fit just snug.
Rabbit out the ends the same width as itself and the same depth as the groves.
Test fit.
Quick sanding to eliminate slivers.
Another test fit.
Make sure it fits nicely over the 1020 tray.
Tape off one end panel and layout centers for the size insert you will use and drill holes. This one is for a 98 cell.
After the tape is removed, scrap any burrs off with a blade.
Drill a hole in the end for the vacuum hose, the extensions will usually be tapered, seating for a nice tight fit.
Screw the corners together and give it a test run. Dump a pile on and shake it back and forth till the seeds find a hole; then dump the excess out.
As you can see there are some doubles, for the most part that matters not to me but smaller holes will eliminate this issue.
Staged and ready to go. WooHoo
