Hi Peter

I have re-designed my attachment points on the blades for the lock down to a much lighter arrangement. I am taking the boat for a test run on Lake Bonney on Sunday, along with about 5 others to shake out the cobwebs. Once I am happy the design is sound I will take some photos and explain the nuts & bolts of it. If not its back to the drawing board..
The other option is to send your blades to AHPC & they will insert a bracket to take the lock down assy.

Cheers

Andrew
