First, the plywood form was assembled and placed on the bed lined up with the all the guidelines. Some heavy broken patio stones (free discarded stuff from a neighbour) were placed on top to weight down the form.

Following the pattern on the building bed used for the model canoe, a total of 13 holes were drilled on each side of the boat, for a total of 26. Given that bed is made with nominal 2x10 board, the thickness drilled was about 1½". This took a lot of work with my low-budget drill, but the job eventually got done (noisy!). Once the holes were completed, I did a dry run by placing the stakes in the holes to check for "snugness". All is well and I can now proceed.

The pot and grill under the bed were picked up at a roadside flea-market that I always pass by when heading up here. This time around, I stopped to checked it out and ended up with an appropriate pot and grill (plus some other stuff) for $2. I'm intending to use this pot to boil roots and make the pine pitch (which ruins cookware) over an open campfire when the time comes.
