Wrap Around (Full Perimeter) Bumpers

Ok. So here is an option if someone has basic sewing machine skills.

Materials:
1)plywood
2)wood screws
3)drill and bit to pre drill holes
4)Carpenters penciled or something to leave a mark that won’t bleed.
5)Cloth of correct colors (16" wide by robot frame perimeter+ (3/4" *4 (for plywood thickness) + (noodle diameter * 8) + a few extra inches(for a 120" frame this would be 120+3+20+extra = 143" + a few extra (so 146ish)
6) tape to temporarily attach noodles

Making them:

  1. Plywood ring of correct dimensions for your frame with some reinforcing angle brackets and mounting hardware. Leave room for extra cloth to wrap around (1/8 inch extra on length and width beyond what is needed for mounting hardware is probably fine.)

  2. mark on plywood where mounting hardware goes

  3. attach noodles temporarily with masking tape

  4. this tool from 1x4 lumber, this is a template to help with the corners.

  5. each side is the plywood length+ 2 noodle diameters

  6. mark out those distances from your starting side (keep in mind to use some of the extra overlap, so, start 1.5" in, go half of side length+ a noodle diameter, make a mark, go the next side + 2 diameters, …, last half side + 1 noodle diameter+ 1.5" overlap.

  7. mark using the short side of the tool mirror the profile on either side of the marks you have been making. Something like this (ignore my scribble mistake) , my paper is too small, so the areas labeled “cut” should be little irregular pentagons

  8. check the plywood frame with noodles attached temporarily.

  9. now you can put the numbers on (carefully about right side up) however you want

  10. carefully cut or fold the corners and ideally getting them sewn to resemble this around all corners, then sew the extra overlap together:

  11. assemble as you would with any other bumper, holding noodles in place, stapling fabric to wood, etc.
