You guys might have seen these a while back:
QUESTIONS:
But, for a more SF tech feel in the foam wall impressions . . .
Could a foam-embossing roller (about 2 inch diameter) be made using Lego cogs, gears, sprockets, pulley hubs and axles?
If so, of all the millions of Lego bits sold, how do you know which gears and pulleys have the same outer diameter and use the same axle type? What language should I be looking for to get the same diameters?
And how could you lock the gears at each end of the axle to keep them from slipping out?
Any Lego gurus out there that could help me make sense of so much variety?
I haven't seen a Lego up close in ages, so please explain as if to a total newbie.
As you can see from just looking at these listings, a lot of Lego pieces were definitely not around when I was growing up. All we had was standard rectangular blocks and some slopes:
