Hi Eric,
Did you use that superglue I messaged you about? How did you find it?

So just how well does super glue work for brass parts ?

HI can't remember the name of the seller, but if you go on E-bay and type solder paste into the search thingy a couple of places come up. I still believe this will be the best way to go but only time will tell. AlanV.

Brass parts glue extremely well with superglue, only problem is that the part must line up exactly, as the glue gives you no time to position! (as recommended in the tips section, use a toothpick with bluetack to hold the small pieces while settling down accurately).

Ref solder paste - I bought some as the blurb seems to suggest that all you had to do was spot some down and then join with a soldering iron. It turned out to be a powerful flux, that etchs into most materials, but still needs seperate solder! It seems to have been designed to be "painted" onto printed circuit boards before they are dipped into hot solder baths, where a good flux is critical. I found no advatange over my normal reel of solder which has the flux built into it. (p.s. unlike some fluxes, it is also designed to be easy to clean off, essential with PC boards.)

Hi Eric, Did you use that superglue I messaged you about? How did you find it? Hi Afkmatrix, yes it was the thin CA glue I used, and it worked well, it ran along the join line (capiliry action) and only had to be held for several seconds. I found that a lump of Blutac was very usfull for holding one part in place while I held the othe part in one hand with tweezers, and the glue in the other.

I have used 'Vital bond' superglue from my local model shop for the brass parts. It comes in 3 different types, 'runney', 'semi runney' and 'gel'. I used the runney one (blue lid), it's a CA based glue. I like using this glue, as the bottle has got a long small 'top', so only a tiny amount of glue comes out. It also has a long shelf life.
Now if I could only find the missing porthole cover that I lost in my carpet.

Superglue works on brass much better is the two surfaces glued are slightly roughened with very fine wet-n-dry (I use 800 grit) to give the surface a key. Make sure it is clean and grease free as well.
If you leave the surface shiney, or dirty the part will ping off quite easily. Have a practice with some off cuts from the fret if you want to see the difference keying the surface makes.

The main problem I have with the etched parts are fingerprint marks. I always wash my hands before touching the etched parts, but I always get prints on them.
I need to find something to clean the parts before they are painted, otherwise the paint might not stick to the brass.

Use a toothbrush but be careful as prolonged immersion in thinners makes the toothbrush bristles fall out! ;D

Thanks for the tip, Mike. But thinners may loosen the super glue. I've got some thinner in the shed, I think I will give it a go. I report back with the results tomorrow (Thursday).

Another method of using super glue. If the joint is an internal one that will not be seen, (eg. the inside corners of a box), tack the pieces together with superglue and then sprinkle a coating of baking powder along the join. Drop some superglue onto the baking powder and you will get an instant fillet that sets like steel!

Hi again to get rid of fingerprints or grease use some surgical spirit on a cotton bud. I find that works a treat. AlanV
