Re: Mixing Media Within the Mechanics
toggle quoted messageShow quoted text
Interesting question. It will be interesting reading the responses.
In my case:
- I like to work with wood...so start there.
- I like "smooth and quiet".
- I never rotate (or slide) wood inside of wood. I always use either a nylon bushing (for a partial rotation) or a ball bearing assembly (for full rotation).
- The size automata that I create cause me to work with shafts 1/8, 3/16, and 1/4" diameter.
- If I am doing something simple that is not high tolerance I will use a wood shaft inside nylon bearings. The wood dowels are not the right size for the ball bearing assemblies...they are always too large...and a pain to install.
- I use 1/4" stainless steel shafting and ball bearings for things that rotate.
- When attaching things to the stainless shaft I normal clamp onto the shaft.
- The 1/4" shafting comes in a D profile. I prefer using this D profile because it permits the clamps to get a better grip.
- Hubs are also available.
- I source my shafting, bearings, hubs, and spacers from ServoCity.com.

I was wondering about the pros and cons of mixing media within the mechanics of our autuomata. For example could I use a brass, aluminum or steel rod in place of a wooden dowel rod, but then have wooden cams, cranks, gears and levels attached to the metal rod? Over a certain length I guess all rods tend to flex. Or would it be wiser to simply add support posts at the point of flex? I hope this makes sense.
