Just to remind you, I have started the Building Jig a few days ago:
Now I am adding the uprights, which I bolt to the base. I then cut out the moulds and screw them to the uprights:
Notice the black clamps holding the uprights to the base. These are the most frequently used tools I have and it pleases me to be using them as I made them when I was 15 years old.
The biggest problem I'm finding is space in which to work as the jig is taking up most of the working area. I have to take a Sterling Board from where I have them stacked and get it into a horizontal position three feet off the floor.
They might not look it but they are very heavy and awkward to be manhandled by one person.
Once I have it horizontal, I mark out on it the shape of the Mould, very accurately, using the information on the plans I bought.
Next I use a jigsaw to cut the mould from the Sterling board, then screw it to the appropriate uprights.
All I'm doing here is summarizing the process in order that I can give you an update. I will try to photograph the process step by step tomorrow, it took me two moulds to get from 'trial & error' to a procedure for working.
