This wheelchair, like other steel tube chairs, should use only thin-wall tubing. To keep costs down, check with various sources of materials and ask at small fix-it shops for advice and possibly even some free scrap material. Metal scrap heaps are great for materials.
- Review drawings. Adjust measurements to fit child.
- Cut all sections of square tubing. Make sure that matching tubes are equal in length.
- Drill holes in bottom tubes and pass the threaded rod through them. Adjust nuts until a ‘V’ is formed. (Weld tip of ‘V’ for extra strength.)
- Drill all holes in seat tubes. Pass threaded bolt through seat holes.
- Drill holes in back support tubes and front caster tubes.
Bolt to frame.
- Weld axle nuts to ends of axle tube. Drill holes for U-bolts and bolt axle tube to frame.
- Weld front caster forks to front tubes.
- Sew cloth back and seat supports. Screw into place.
- Cut out and bolt wood footrest to frame. (Use wedges to get the angle right.)
- Attach axle tube with U-bolts and put on the wheels.
- Paint frame to help keep tubes from rusting (if not galvanized).
