Tube bending
My dad was in LAME in the RAAF during the war and regularly used tube filling methods to bend hydraulic lines together with a tube bender. There are several methods of doing this ,some that I am aware of are Bismuth (melts in boiling water) Cerrobend I think is its commercial name. Frozen soapy water also works they tell me and I have even heard of packing with sand but not sure how it would work.
Has anyone here tried it I have some bismuth from another project and keen to give it a try.
