<div>Ian,</div><div>Thank you, if you want to print some then I can just keep building and allow for the size. The shaft for the big gear is 5\8 and the shaft for the small gear is 1\4 inch. I do not have a weight budget, just keeping at light as I can. The nice thing with plastic is the low density. In a perfect world the the large gear would be 3 inch dia and the small gear would be 1 inch.</div><div>The thickness can be 1\2 inch giving it some extra strength. I can drill out the centre with my lathe. </div><div>Thank you</div><div>Hank</div><div> </div>

<div>Hi Ian,</div><div>I am stuck on plastic for weight, but I am probably over thinking that. It is, after all, such a tiny part. I never thought of Amazon, I will check that out.
