Someone went to the trouble of cobbling this together to show me a way - Super appreciated!!!

If you wanted a stand-alone clutch unit then a floating pulley that could be forced into contact with a moving one or a stationary block could give you both clutch and brake.

The Design Shop / Advice on building s simple ‘clutch’ to stop a driven accessory
« Last post by Jim Dobson on September 28, 2025, 11:11:35 PM »I’m after some advice to build a simple ‘clutch’ that can be activated by a lever to disengage a running accessory that is being run by a belt off an engine.
If in the photo below where I have drawn the red line (and that belt was longer) what type of simple ‘clutch’ could be built to be able to work to disengage the belt with a lever moved one way and then re-engage the belt with the lever moved back? This would be an extremely handy thing for me to have when running accessories of steam engines and H&M engines etc
I’ve wracked my brain and everything I have come up with would be a dud……any ideas?
Hope I’ve made some sort of sense with the above!

The Transmission slowed the pump down nicely and was well matched to the H&M engine and this is one of the jobs these types of engines would have done back in the day.

I get the Qualters and Smith saw running, and adjust the hydraulics, and almost get it right, but I have decided to strip the lift ram next week to check the settings as it sometimes doesnt cut quite through before it goes into lift mode! We finish the wire mesh around the trees to make the fence dog proof in both directions, and clear Damson wood! Friday I get my Honda mower running after some tinkering and clear my garden ready for fencing and finishing off at Ratten row! It's only the work that is keeping us alive, as I always say to Keith! Long may it continue!
Phil, in warm and Bootiful East Yorkshire!

What all the black powder shooters use to stop the burnt black powder from rusting their pistols and rifles.
Its just Ballistol (which is water soluble) mixed with water. Works great for H&M engines so that when you've emptied the hoppers and the water evaporates its protected by the Ballistol.
Who coined 'Moose Milk' ..... I don't have any idea.
