Cost about $40 in parts from the local big hardware store including the PVC glue and spray on adhesive for the padding.<br /><br />Took it for a test drive with a 7'6\" x 22\" x 3\" funboard and it performed well. Ran over bumps and potholes and my kids with no problems. Rode it in cross-wind and head-on wind and it handled it well.<br /><br />IMG_0047.jpgIMG_0048.jpgIMG_0046.jpg
Thanks or the link. I saw the tutorial and had to modify his construction. The shifter cables run on the outside of the lower front tube so I couldn't mount the second support there. I added the bungees as a shock-absorber to keep the longer board from oscillating.
I'll try the duct tape if the squeaking gets to me - thanks for the tip.
UPDATE: I have put about 1-2 road hours on the rack with everything from a 5'4" Biscuit to a 7'6" funboard. No problems with handling, wind, etc. If anyone wants to build one (and the pix aren't enough info) let me know and I'll pass on any info/tips that my brain can remember.
