GRILL PROJECT
Here are some
dimensions, tips, etc.
Height of barrel
frame - 37"
Width of frame -
24"
Length of frame -
37 1/2"
Rack extends
11" out around two sides
Materials used:
- 1 inch square
tubing 16 gauge
- 3/4 expanded
metal #9 flat
- 1/2 round cold
rolled (for axles)
- 8 " diameter
wheels (Harbor Freight)
A few tips to
keep in mind:
- Remember to allow
4" for wheels when building back of frame to keep it level
- Tack everything
together until it is completely built (makes it easier to disassemble if
they mess up)
- Constantly check
for square - if they don't keep it square, the barrel won't cradle in frame.
- My barrels had
honey in them. Avoid barrels that had chemicals or anything
explosive. Cut barrel with recip saw. Drill hole big enough for saw
blade to enter. (It is loud when you saw!)
- Big tip!
Cut top line of barell - stop and then weld hinges on. Then finish
cutting out barrel. That way you don't have to try to hold the lid in
place while you are welding hinges on.
- Cooking grate is
removable to clean grill.
- Put several
shovelfuls of sand in the bottom of the barrel to keep barrel from getting too
hot and rusting out.
PICTURE FRAME PROJECT
Directions for building picture frames
Materials needed
1 X 4 lumber – 10 feet
Wood Glue
Small finishing nails (I use air gun to shoot them)
Plexiglass
Cardboard boxes (for backing)
Glazing points
Step 1. Dado a groove down the center of the 1 x 4. It should be ¾ inche wide and 3/8 inch deep. If you don’t have a dado blade you could use a regular table saw blade and keep adjusting it over. Then clean the groove with a cold chisel.
Step 2. Rip the 1 x 4 into 2 parts, down the center of the dado.
Step 3. Each student needs to cut a 40 inch piece. It is important that all 4 of their pieces come from the same stick.
Step 4. Set up a jig on a radial saw and cut 45 degree angles. It is easier to cut all the short sides (2 per frame) and all the long sides (2 per frame) at the same time. Cut all angles with the dado cut up and against the backstop of the saw. See pictures for the correct lengths.
Step 5. Glue a long side and short side together. Repeat with the other two. Glue pieces so that the sides will match up with the dado all on the same side. For added stability, we shot a finishing nail into the joints as well. Use 90 degree clamps.
Step 6. Glue the last 2 joints together which will have all 4 joints of the frame glued. Shoot with finishing nails. (optional)
Step 7. Cut plexiglass and cardboard to fit in the dado groove. Use glazing points to hold them in.
Step 8. Drill two holes in the back to attach to a nail in the wall. Drill one for a horizontal picture and one for a vertical picture. Set the stop on your drill press so the student doesn’t drill too deep. Use a forstner bit for a smoother hole.
Step 9. Optional – Use a router to put a roundover edge on the frame.
Step 10. Sand and finish. Several of my students used a propane torch and lightly burned the frame. Be sure they take the plexiglass and cardboard out first!
