Making copper reducers/funnels

[woodduck]

Pi (sorry don't have the pi symbol on my phone,its the funny looking one like 2 T's together) =/is 3.1416. So when you see the pi symbol replace it with 3.1416.

does that make sence?

Ah ha got it. Il test it tomorrow.
Cheers wood :greetings-waveyellow:

No problems mate have fun :handgestures-thumbupleft:

i got approx 193deg for the 3/4" to 2" with a 50ml length, and the 1" to 2" degrees is the same for 2" to 4" (161 deg).

On to it like a fat kid on a cupcake.
Thanks fellas :handgestures-thumbupleft:

Good to hear, have fun with it. And you told your math teacher you'd never use algebra :laughing-rolling: :laughing-rolling: :laughing-rolling:

[rumdidlydum]

Haha yeah. That was after throwing tom thumbs at her. :laughing-rolling:

Nice simple instructions. very cool thanks.

One template made looks right. :D

When forming these whats the best way to go about it, so they dont end up looking like they were run over by a truck? Get a set of sheet metal rollers the way to go? :-B

[aussiebrewer]

how much do you anneal your copper bluc? you will find if you get it red hot and i mean real hot you can bend and manipulate it with your fingers and get it fairly right.

from there a few small taps or even pushes with the fingers around a pipe will work, even a 1/2" pipe or hard drawn copper. if it hardens while working it with fingers hit it again with some heat to bright red and then go again and it will be easy as to bend the copper. anneal as many times as needed. when i started annealing i didnt go to red hot and had trouble flattening and bending copper but once i did go red hot it was sooo easy to bend the copper with a finger. i always go red hot now as in brazing temps or hotter

Have not attempted making anything from scratch yet just sticking pipe and capilary fittings together with soft solder, thanks for tips will keep them in mind :handgestures-thumbupleft:

I'm going to give this thread a BUMP as looking for it does take ages :angry-banghead:

Anyway with this thread up the front it will give new members a look into how easy it really is to make reducers and funnels etc
