The Bed
Hope this works!!!
Materials needed:
1\16th" thick 1/4" wide basswood found in rc plane area.
(I use bass not balsa)
.10" (2.5mm) evergreen #273 I Beams
cardstock
tape
tenax cement or similar
Start by cutting out a template that fits snugly into the box, out of cardstock
Cut 2 each pcs of I Beam the EXACT width needed.these are the front and rear.With a sharp blade remove 3 of the 4 lips on each.
Next cut as many planks as you will need...lay them side by side on template, the number needed depends on the width of your bed 6 or 7 is common.These should be the length of the template
Now cut lengths of I Beam to proper length 1 less than planks
Inspect wood planks and I Beams for burrs etc and remove. Now lay out your planks and I Beamson top of the template ,work slowly and you will dry fit the parts with the tape. If your finished width is wider than your template, remove the center 1 or 2 planks and thin them for the correct fit.
Once satisfied cement weld 1 end to the ends of the I Beams the lip
