You might be quite correct on that John, but if it does allow a larger or stronger spark to be produced, then advantage has to be taken of it. So a bit of a slack drive it is. Jack, I received my unit back today, and as promised, he has sent me a specially made sintered neo magnet, that looks to be either chrome or nickel plated to make it a little stronger, as they are renowned for being a little susceptible to shock loads. But because of the the size it has been made to means that a slight mod to the main frame and a couple of new parts will need to be made before it can be tested again, so that might take a bit of time before I can get around to it.

Hi Bogs noted that you were using some small roller chain. Looking at the dimensions of the chain you are using it seems to me that this is still rather oversized and out of scale with the model. as an alternative roller chain may I suggest the following miniature stainless steel chain from Precision Scale Model Engineering ( psme@psmescale.com ): product code: MRC-1475 0.1475 (3.75mm) pitch roller chain Price: approximately $US 3.75 per inch with a minimum of 6 inches per order. there is also a good range of sprockets available from the same supplier. I have been dealing with the PSME owner, Lawrence DeMilo for many years and find him a great supplier. Hope this assists have fun Bernard * |

Bernard, Many thanks for taking the trouble to reply and attempting to assist me. But in reality, 6mm chain and sprockets will be perfect for the job to come. The engine it will be fitted onto actually has two rather large 9" flywheels, unlike the very small engine that was shown in the video. Thanks again Bogs |
