I picked up an old 1,000 lb. floor scale a while back (don't ask me why; I just did), and it now has a place in the shop. Problem is that it's heavy, so a bit hard to get to things hanging on the wall behind it. Then it dawned on me "oh yeah, those holes at the corners are for wheels", so that I could simly roll it out as needed. So, I will be watching for some old cast iron wheels for it, but in the mean time, was thinking that I could make some wheels out of oak or maple, as I have some vintage, well aged selections of both in the barn. So, I need to make 4 wheels, something in the range of 2-4" O.D. and bored for a 3/4" axle, and my questions are a) which would be best, maple or oak, and b) it's only going to move something like 3' out and 3' back, so do I need to make a bronze or other bushing, or should the wood on the shoulder of a bolt be sufficient for maybe a couple of years until I find some period wheels for it? And just for the sake of a bit of history, for anyone under, oh I don't know, maybe 40 or 50 or so, maybe older, the intrigue of this scale to me is that it seems they used to be in about every other store up and down main street. My wife and I grew up in a town small enough that it got it's first traffic light during or after the time we were in high school, and we counted at least 6 scales like this that we can remember in our little town. Anyway, enough of that; just wondered if anyone had any thoughts. Thank you.
