| Bending Brass into a Ring |
| << < (2/3) > >> |
| Jasonb:
Put a big jubilee clip around it. Its very hard to bend or even roll a strip right to the ends, you may have to do a little work with a block of wood and a hammer over a slightly smaller dia former once its soldered up. |
| mklotz:
After annealing, wrap it 450 degrees (turn and a quarter) around your former, then saw through at the 360 degree point, flatten, and then solder the two ends. |
| Jasonb:
I think hes already cut the metal but it is a good suggestion. Chris if you have already cut the metal you may not get the size you want as the method of calculating the length is not measured on the outside or inside dia it is approx 1/3 of the way through the metal. So given your metal thickness the actual dia will likely be 59.3mm OD. J |
| 75Plus:
Chris, Have you considered using a bit of brass pipe? I have used it to make weights for weight driven clocks many times. I have a piece 58.42mm dia. with 3.33mm wall thickness that I would be happy to share with you. Check your PM box. Joe |

:bugeye: :bugeye: Very very sorry! I of course read all your replies and used the advice given here to solve my problem. I posted a link to my ring sundial and presumed I had replied here to say thanks for the help but I hadn`t! http://madmodder.net/index.php?topic=5641.0 Just to clarify incase anyone else has a similar problem, I heated to cherry red and quenched as suggested initially by Stew and many others. This immediately solved 99% of my problems. The ring bent much more easily and had virtually no spring to it! It was incredible really what must be happening at a molecular level!! It went from virtually not being able to push the two ends together to being able to do it in one hand with thumb and forefinger!! Marv - Jason was correct, I had already cut to size but next time, your method is much more sensible. I did however use your advice and slightly overbend it around a smaller former (only by a small amount) and by the time I let go, it pretty much sprung back by a fraction to perfectly mate the two ends. So many thanks to all of you for your suggestions and sorry for the lateness of the reply! Chris |
