Retractable Casters 1

[DeSimulacra]

I am designing a device that needs retractable casters. I found an example on-line in the Brunson 230-F but cannot work out how to design this. Has anyone got an idea?

Requirements: Retract/deploy 3 or 4 casters using foot or hand lever. Casters must lift load of approx. 200# approx 1/2" off floor.

I could buy a Brunson Stand and modify it but that would be more expensive and not really what I need.

Tanks,

DeSim

Mint Julep,
Was that your own design?

No, I can't take credit for the design. It's rather elegant I thought.

In fact, it's not even my saw, just a picture I found on the internet. I'm fortunate enough to have a sufficiently large shop space where I don't need to move my table saw.

Try Grainger of McMaster Carr??

Is there some reason that a retractable foot (with the caster remaining stationary) not an option?

Quote "Is there some reason that a retractable foot (with the caster remaining stationary) not an option? " Yes there is. I need the casters to retract.

Mint you got me thinking

 

[DeSimulacra]

oh and yes I have tried all caster sources including listed. Mint's idea is close and may be adaptable in Steel

Thanks Berkshire and SnTMan but yes I have. I probably could make those work but hope for something more oh hate to use this word but "elegant".

Been to Home Depot or LOWES to see the casters and legs they use on those roll around steel step ladders?
Some use springs above the casters just strong enuff to raise the step ladder feet slightly off the ground, but a person's weight plants it solidly on the floor.
