I have a friend that is a potter. and the other day she asked me to make her a couple of moulds for making trays. Generally pottery is thrown on a wheel, ( a mud lathe?!) but another way to shape the clay is moulding it and wood makes the best moulds, I was told.
|mould with the mud on it|
|8 x 16 mould|
|square mould 8 x 8|
Making these moulds is not high art and it was nice to find purpose for some of the bits of wood that are still laying around in piles. This imagining oneself as the most primitive of pattern makers. One day I will have to buy more wood, but 'not today'.
Making the moulds was an exercise in 45 degree angles. A sliding mitre saw makes short work of a project like this. I bought my 'slider' quite a few years ago and have been working it hard. Bosch has continued to develop their saws, and I would certainly look to Bosch for my next saw too.
If you were to make a dedicated 8 sides mould it would be like cutting crown moulding for a tiny, tiny room. If my friend is interested I would give it a try.
