Hi guys,

I'm a "new boy "I just wonder if anyone has any idea about the springs on the front of my 2in Ransome Sims and Jefferies whether to make them out of gauge plate and temper them back of Phosphor bronze any thoughts?

Spring steel, available in various sizes of flat strip.

I made my 3" scale ones from spring steel strip, once cut and rolled to the correct shape I treated them to a bath of molten lead to make them stay in shape. Springs do not "scale" very well, if you use correct 2" scale thickness and quantity of leaves, you will find they are pretty much solid, I have heard of people substituting some of the leaves with something flexible like Tufnol to try and overcome this problem.

Having said that I wouldn't worry too much about having working springs on such a small model anyway especially on the back axle, you might be giving yourself more problems with things like drive gear meshing etc. As for the front I would just make it look right even if it doesn't work.

I am sure there will be more responses with advice for you, but that is my 2p worth.

Phil

Thanks Jason, Who supplies small quantities? I'm looking for 1/16×3/8 wide I guess about 18ins.

[JasonBModerator @jasonb]

Reeves do it in 24" lengths, 16swg would be closest and they have several width in the drop down, Blackgates, Polly etc also do it but Reeves was just easier to look at.

Andy, I have some spring steel in sheet form I will never use. I can cut you off a bit FOC. PM me if this is of interest.

The annealed strip/sheet is easier to work than a ready hardened spring

Andy, if you send me your email in a private message we can take it from there, rather than put your email in the forum pages.

Many years ago I needed to make springs for a Clayton Lorry and found a small firm in Sheffield that made springs for false legs etc. This was the correct shape with rounded edges and supplied not hardened so could still be put through rollers to give it shape but was still springy enough.

I've tried to find the company but without success but did find this company that supplies small quantities and accepts Paypal or credit cards.

As usual, I have no connections with this firm whatsoever.
