awesome work nine six
yeah I could use 7075 its a little harder to source but way better than 6061 in terms of raw strength Thermally though they expand at similar rates. I would have to coat it though because 7075 isnt as corrosion resistant. i like steel because it wont expand as much as aluminium so it will hold tolerance better.
I got my tube in today if people are interested i can get a batch ordered this week. and make a set
I want to make them at my local machinist because I can trace the materials and make sure they arent being made from sub par materials. If my name is going to be associated with something I cant have parts breaking in service it will be a little more but better. Im nervous about using non traceable parts inside an engine.
If i can get at least 5 people to say they will buy a set ill move on it. Ill also beat him up on the price to get us a better deal. its a numbers game though the more units i order the lower the price
