Indeed they are.

I like your way of thinking 1Q. I'm currently working on some skis. The bottom is sheeted with an inside out Keystone beer can. The theory is the "special lining" is going to be super slick on snow.

Litho plate works well too, if you need a .010" shim.

I bet it will be, too. It sounds a bit scary even. LoL!

I bet you're right. I used to have a small pile of that. I wish I had kept it when I moved. I know where to get more at the local university printmaking classroom.

I love the smell of Castor!

I have noticed that some engines do in fact smell different. I have always blamed the quality of the materials used for manufacture of the particular engine as my fuel has been consistent. The engines that 'smelled' were labeled "cheaper metal" by my Dad and I. We also felt those engines needed more oil than the one's we considered thoroughbreds. That may not find people that agree, but it was our observation through several decades of running glow engines. It is much less noticeable with the more current ABC/ ABN types.

For me, the only difference in smell I notice is 2-stroke to 4-stroke. Most all of my 2-strokes smell the same regardless of nitro content (the 30% car fuel burns the nose more but smells the same otherwise) and the 4-strokes smell the same but the two are a world apart if you run a 2C and a 4C side by side.
