I believe you have it backwards. The surface bubble does not control the rising stream of micro-bubbles, the rising stream drives the...

SMA is suitable so long as it is in close contact to the conductive enclosure, without gaps that could act as short slot antennas. The...

You must learn to think about conductive surfaces differently. At 8 GHz the chassis or external ground connection, between enclosure...

You really need to find someone local who has a lathe to make the components, from either metal or timber. The type of lathe available...

But not in direct sunlight, with significant vibration, or flexing at the contact.

https://en.wikipedia.org/wiki/Bicycle_rollers Notice that the front wheel drum (roller) is driven by a belt or chain from a rear drum...

A bicycle is designed to roll freely across a flat surface, on a wheel with a radius of about 15". You have rollers with a radius of...

The problem I see with RTV silicone, is that it will bond well to itself, but poorly to aluminium or glass. Still, if the joint is...

I expect that the 40% counterweight is a compromise between reducing the peak ±load on the motor, and increasing the rate of...

What load variation, from minimum to maximum, is being lifted? What load is the geared traction unit specified to lift?

Differential thermal expansion will be a problem if the glue is too good, or the aluminium is too thick. Epoxy or superglue would last...

The 620xRS bearings have rubber lip seals that will drag if dry, and may stop the rollers spinning freely. If after cleaning and oiling...

Welcome to PF. At first reading, it might seem to be OK, but there will always be safety concerns during operation. It is very hard to...

The bike wheel is not dropping down far between the rollers, multiplying the friction load, so that is not a problem. I suspect the...

Welcome to PF. What is the diameter of the rollers? How far apart are the rollers? What is the rear wheel outer diameter? What tire...
