well its gonna be small piping, probably internal diameter of no more than 1/3 inch!
is piping easy to bend if i use a small blow torch to heat it? just be alot nicer lines if i can bend it rather than use angle joints!
Bending tube often ends up with the tube collapsing if you don't support it.
Plumbers often used special springs to provide the support.http://www.tooled-up.com/MicroCategory.asp?MAN=Bending-Springs&CID=9&SCID=71&MCID=474
you can also buy special pipe bending toolshttp://www.tooled-up.com/SubCategory.asp?CID=9&SCID=71
If you don't want to fork out too much money on somethng you aren't going to use then there are other ways.
One way is sealing one end with tape and then filling with sand, taping up the other end and then bending.
You can also fill the tube with melted vaseline or wax and bend when set, just heat it up and pour it out.
When working with metal it becomes "Work Hardened
". Ths means he metal becomes harder which can be good for the finished article but when your building means it's harder to bend and it can split (metal fatigue, bend the head and handle of a spoon back an forth a few times and you see the results)
To soften a work hardened bit of copper, heat it with a torch (the same torch you use to solder) till it glows red. This will make it soft and easy to bend. (do this before
you put the vaseline in
) Google anealing
for more info.
