many thx

I'd just bend the brass around a piece of round bar, roughly the same size as the internal diameter of the ring you want to make. then continue to bend the brass around the bar to make a kind of spring, then saw across to make the separate rings.

Hi MOB,

It all depends on the diameter of circle required.

Normally I just do it as Alan suggests but anneal it first, that way it will be almost the same size as what you are wrapping it around, otherwise it tends to spring open too much.

For larger than average I use a set of slip rolls with the round grooves on the rollers designed for doing this sort of job.

MIB,

This will show you a piccy of a slip roll. If you look carefully at the rolls you will see some grooves at the end, these are for fabricating rings.

There is also the hand held copper pipe bender. I use one of them for pipe work on the steam plant. I'm sure with some annealing it will be OK with brass tube as well.

What diameter are you trying to get to?

and the second is at a rough guess is 3 inches pic included

That is a wrap around paint tin job, but as I said before anneal the brass first. Just heat it to a medium red colour and either drop it into water or let it cool down naturally, if it hardens up before you have finished bending, just repeat the heat process. Not a job for machinery.

Brass Wintergarten rings

Hello MIB, do you mean like this ?, i heated them up a bit to get them more supple then found a paint tin of the correct size and bent away a little at a time and hey presto done. Hope its of some use sub.

Wintergarten rails

Hello MIB.

I use 2mm dia brass rod or 1/16 in old money. Put it against the tin and bend it from the centre outwards not from one end, and do it equally at both sides at the same time. You should be able to do it with the rod cold as its only thin.

Bend it past the centre line and it will spring back a bit then bend the sides for the tower sides when the dia is right. If it is a little out you can adjust it when you put the uprights on and solder them to the ring. Go slowly and use the full 12 onch rod don't use tube.

Hope this is of use if not I dont think you can buy it pre-done anywhere

:regards:

hi

sub tried that mate and all that happens is the thing justs springs back out!!

 

[bogstandard]

You were told before, it has GOT TO BE SOFTENED BY HEATING, OTHERWISE IT SPRINGS BACK.

If you live anywhere near Crewe, bring it round and I will do it for you. While you wait

Is this free brass bending service open to other members of the forums? Watch out or you will be inundated with Scale modellers on your doorstep with puppy dog eyes, holding pieces of brass rod in outstretched hands!

:dog:

Isn't that why men invented the art of scale modeling?

Regarding the Brass - it's just a case of annealing the brass and then trying to figure out just how much the brass springs back after it's bent - so try an assortment of paint cans with a diameter just a fraction less than the radius you are trying to create.

All good modelers toolboxes must contain an assortment of paint cans in a range of sizes!
