Both of the tillers that came my commander were replacements and neither one worked very well. One was only about 4" longer than the original but instead of a slight rise it had a drop in it and it was a knee knocker. The other while it had a similar rise to the origianl it was about 12" too long. It took up a lot of cockpit space to use it. So tonight I cut up one of the old combing boards and resawed it into strips 5/16" thick. I built a jig to match the profile in the manual and glued the first one up. I figure it can't hurt to have a spare so I'm going to make two while I'm doing it.
If anyone wants the jig when I'm done with it and is willing to pay the UPS to get it let me know and it's yours.
