Metal Tanks

[Peter Miller]

I have found the article on Tank making.

I will scan it and send it if you PM me your email address.

Hello D for D . As in other post  just make tanks with a butt joint , no tabs needed. Copper will usually occur with glow fuel that contains Nitro Methane , the high the content the quicker the errossion, If that's the correct term , of copper . It will dissolve the copper from bass tube leaving a brittle porous tube of blackened Zinc . Any fuel residue left in the tank will go a dark green colour . Never experienced it it with diesel fuel though .

Some pics of making tin tanks here . Hope its of some help . When you have finished soldering and testing the tank half fill it with some cellulose thinner to dissolve any flux/resin that can block fuel tubes . |Guess how I found out about that .

I have another daft Q from the uninitiated. Does a flat bottomed tank for ff radio assist always leave a bit of fuel at the bottom? Is it best to have a wedge, triangular or round bottom for instance - but this wouldbe harder to make I assume?

[Peter Miller]

A slight wedge shape would work but might be a bit harder to shape but not really a problem.

In the article I give a way of making a clunk tank with the usual rubber bung.

You buy a 20 mm conduit bush. Cut it down to about 5 mm threaded portion and solder that into your tank. Yu can then use the standard rubber bung supplied with plastic tanks.

Wilco, is that then JB Weld you are proposing to seal/construct your metal tank with? The answer to your question is I have no idea if it will stay sealed in such a fuel soaked, vibrating environment. I personally would not trust it.

Den's model supplies Isle of White for a range of traditional model stuff including metal tanks, not used myself but looks good.

[Wilco Wingco]

No Don. It's the low melting point ali rods. Check out the net there are loads of videos showing them being used to repair aluminium drinks cans. Quite large holes can be seen "filled" with little effort and a butane torch.

You could try logging onto www.forum.medwaymfc.org.uk  if that works click on 

Ben Buckle designs in traditional models then onto BB Taylor Craft and scroll to bottom of page one .
