The angle filler adjustment did the job and the sand mould second attempt was very good. I used again my homemade green sand and the aluminum casting was satisfactory.

Casting a new foundry flask (Part II)
Yesterday I casted the second pattern of my new aluminum foundry flask. The first attempt of the sand moulding failed. I had to improve the angle/draft around the patterns handle section. After using more filler, sanding it and then finishing with a coat of varnish.
