Step 5Frame
The frame is pretty straight forward. The outside dimensions are 60-1/2" long by 23" wide. The counter it will live on is 24" wide and I need to leave 1" of clearance for the light brackets.
1. Cut angle iron
2 - 60"
2 - 23"
Set the 60" pieces inside and on top of the 23" pieces. Use a tape measure (or two) to square up the frame. Do this by measuring form corner to corner as show. Adjust the frame until both dimensions are the same.
2. Tack the inside corners (ONLY) so you can make any adjustments necessary.
3. Recheck the frame to make sure it is square and weld the corners solid.
4. Cut two cross braces 23" long and trim both ends of one leg to 45 degrees. This will eliminate a sharp edge when someone reaches under to change the nutrients or perform other maintenance. It also gives your ends a finished professional appearance.
(Note: save the triangles that fall off. They will come in useful later!)
5. I put the frame up side down on some old fence blocks to make installing the cross braces easier and because it will make it easier to check the height for the legs later. Measure the frame 20" from each end and clamp the cross braces as shown
6. Weld the cross brace to the from from the outside. (The frame had been flipped right side up in this picture.
7. Add a small weld on the inside for additional strength.
8. As I goofed and had to shorten my troughs two inches, this is an additional cross brace to support the ends. In making lemon-aid, it will also allow for some curvature of the nutrient feed tubes.
