Galloway 1/4 scale piston ring dimensions.

[ozziemod]

Hi, I have another question re the 1/4 scale Galloway engine I am building, is anyone able to supply me with the optimum dimensions for the piston rings, I am unable to find off the shelf rings 1.3125" here in Oz and so will make my own which I have done in the past quite successfully.
On the plans the ring width is shown as .091 but there is no thickness shown although on the piston drawing it shows a groove depth of .061, I guess I really only need to know the thickness if the width shown .091 is satisfactory?
thanks

I went for 0.125" wide x 0.062" thick on my 1/3rd scale so something like 0.047 to 0.050" thickness would suit your smaller rings
