Did anyone get any valve springs made? If so please could they supply details?

Are the springs the same for all sizes of engine?

Thank you in advance for any replies.

I didn’t in the end, but I do need 1. Also a fowler safety valve spring?

Tested Spring Co made me a batch of safety springs once . The last of these were stolen from me by a previous TT member many years ago ; yes it still riles me . They can no doubt reproduce , different weights for single and compound . They may have particulars , ref my order , many years ago . Otherwise a drawing is available ex MERL .
The slide valve spring is only there to stop the thing flapping around , I doubt that it much affects performance .

I had a safety valve spring done recently pm me if you like I can pass on my order/inv number.
I will need to get some of the valve springs for my DN1 if someone has a drawing?

Tested spring has made me springs without a problem in the past. Made from the details of a works drawing

They did supply ours for the K7. Very pleased with the speed of delivery, cost and quality

Tested spring made ours from the original fowler drawing.
