What's your technical background?
Personally I have worked as a pipe fitter on larger construction projects such as hospitals and office buildings so I do understand the concepts better than most. Hydro dynamics, thermo dynamics are concepts I understand and can apply to a computer loop. Hell if I did a hardline build my cuts would be quite accurate because I have done it on a large scale even if I haven't built a loop in a computer before.
Based on my experience of flow analysis on a large scale and stuff like that requires expensive equipment if you want to do it right. As [USER=10]@Wahaha360[/USER] could explain, machining time is very expensive and might not be worth the 1 or 2 degrees at the end of the day.
You need to keep in mind that this is a one man operation with limited resources. Yes he wants to give you the best product possible but there is a point where the cost out weighs the benefits.
If you are a mechanical engineer, have a background in this area or went to MIT or Cal Tech then I will shut my mouth.
I am not trying to be an ass, I am just trying to be realistic and remind people that there are limits to the resources these creators have. In many cases these are passion projects developed by people with a full time job and other financial commitments.
Also if I'm not mistaken even though the law isn't my area of expertise. Optimus can take you to court for stealing their design if you try to profit off of it.
