In this Instructable I will show you step by step how to make a drying tower to hold rectangle drying racks.
Dehydrator List of tools:
1/16" Drill Bit
Mitre' chop saw or back saw and mitre box
3/16" drill bit
Screw tips for drill extention- hex and or Phillips/cross tip
Caulking gun or small tube of caulk
Bill of Materials:
Sheet rock screws- 16 ea
#8x3/4" screws, or hex head self taping screws
1-1/4" sheet rock screws-12
Foam gap filler
1 sheet 1/4"x4"x8" plywood or other siding material
8'x2'panelized roofing clear or other clear sheeting
2-2'x18" min pieces of galvanized or other sheet metal (for solar collector and heat shield inside)
12 ea 1"x3"x8" spruce for framing and rails for racks
2 ea hinges for door
Netting to keep bugs out of openings
PVC pipe (optional)
3 porcelain light fixtures pull cord
3 octagon electrical boxes
Step 1: Side Wall
First you will need a 4'x8' sheet of 1/8 inch thick plywood.
Step 2: SIde Supports
Next its time to cut your side wall support braces.
1. Cut two boards that are 38" long and sqare at the ends.
2. Cut two more boards that are 30 5/8" at there longest point. Next you need to cut the top of the boards off at a 20 degree angle.
3. Cut two boards that are 41 1/4" then cut off a 20 degree piece from one end, then cut of a second 20 degree piece perpendicular to the first cut.
4. Cut the last two boards 42 3/4" inches long and cut off a 20 degree piece from the top.
Step 3: Mark Walls
Next you are going to need to lay out your boards as shown in the first image so that you can mark around them. The forth picture shows what the measurements should be and what the wall will look like when you cut it. Now that you have your board marked cut out your wall you will need two of them.
Step 4: Screwing on Support Beams
Next you will need to screw the support beams to the side of the wall. These supports should be on the out side and face away from each other.
Step 5: Back Supports
You now need to cut two boards that are 24" long and screw them to the top and bottom of the back.
Step 6: Front Supports
Now cut two more boards that are 22" long and screw them to the front. You will need to screw them from the side.
Step 7: Roof
You now need to cut a piece for the roof from a piece of PVC roofing cut it 4 feet long. We used tin snips to cut the roofing.
Step 8: Front
Next you need to cut a second piece of the PVC roofing for the front. Cut it 32" long.
Now you need to screw the roof and the front on.
Step 9: Door and Floor
Next cut out a piece for the floor it should be 24"x38 3/4"
Then cut out a piece for the door it should be 24"x42 3/4"
Step 10: Runners for the Racks
You will need to to cut 4 pieces of a 1"x4" board 35" long.
Then cut the boards in half.
And drill a hole in both ends of the board 3 1/2" from each end.
Step 11: Legs
Next you need to add legs to your drying tower if you place each of the legs in a pail of water then bugs cant crawl into your tower.
Cut 4 legs that are 12" long and cut from a 1"x4"
Then mark out a square and draw a line at a 45 degree angle.
Drill two holes one on each side of the diagnle line.
Step 12: Door
You now need to cut four boards to screw around the edges of the door that was cut out earlyer.
The boards need to be cut from a 1"x4"
The first two should be 18 15/16"
The second two should be 42 5/8"
Now screw the boards to the door.
You can add a latch to the middle of the 42 5/8" board.
You will need to to miter out a section of the door so that you can screw the hinge on flush to mount the door to the tower.
Step 13: Solar Heater/Collector
Start with a 2'x18" piece of galvanized or other sheet metal and paint it flat black on both sides.
Step 14: Bend the End
You now need to bend one end of the metal at 30-7/8".
Step 15: Heater
You now need to cut 5 more boards.
2 should be 30 7/8" and be cut from a 1"x4" board
2 should be 30 7/8" and be cut from a 1"x2" board
and the last 1 should be 14 1/2" and be cut from a 1"x2" board
Drill two holes in either end of the 1"x2"s it doesn't matter were you drill the holes but make them around 3"s in.
Now screw thought the black side of the metal and into the 1"x4" boards you should screw them in at about 4". they should be flush with the metal, do this to both sides. Now black your 1"x2" boards to the top of the metal and screw them thought the holes and in to the black side of the metal.
Now screw a 20"x30-7/8" board to the 1"x4" boards.
Step 16: Solar Heater Cover
Now you need to use whats left of your roofing and screw it to the top of the solar heater. We cut a piece off the front to make up for what we needed to cover the heater. Then we cut it to the correct width.
You should have two pieces of roof left you will use them and some wood to cover the front back up later.
Step 17: Cover the Front
You now need to cut two boards to screw to the front. You can see the dimensions in the picture below. Now screw these boards so that they are flush to the bottom and side of the tower.
Now screw the two pieces of plastic to the front.
Step 18: Foam
You now need to fill all the cracks and gaps with clauking and Great Stuff(foam in a can).
DO NOT seal the cracks on the top of the roof this is were all the moist air leaves from.
