Yes, I did think about kart type steering, but I am limited on space and I think, I know a small steering box with a low ratio as in 2;1 would work fine.
I looked at the lakster on Sum's site and it is a quality build, I don't have the space it needs and the layout is different. But good suggestion any way. I did happen to build 4 go-karts in my teen, way back when. I see Sumner went from "salt to salt," he just added a little water.

My thinking now, if I can't find something small and low ratio, I might have to look in industry for a generic, bevel gear box assembly with say 5/8 inch shafts and a small casting in alum or iron. Or, (hope not) I just might have to make one myself with no milling machine. Could be fun.
I get frustrated in my old age when I know what I want and you can't find it anywhere, even for double the expected price.
Maguromic -- the chain device you found isn't what I need. I should have described it more clearly. The chain makes an off-set in the shaft direction. I need a right angle turn in the shaft direction. I did see that chain device on Speedway Parts site when I did my original search. But thanks anyway for the suggestion.
This is the first time I'm building a bike from scratch. And you have to know I'm keeping off the path well traveled. However, these puckerbushes out here are not making this journey one without frustration. But that salt is in my blood. So, I keep going.
