Does anyone know of any casters that can swivel, but can be locked out so that they don't swivel? I don't mean that the wheels lock so they don't rotate, but that they don't swivel.
As it gets colder/darker, it's time for me to start thinking about getting back on my rollers for training. I've been thinking about trying to make them into homemade motion rollers. Something like this:
(not my picture)
Usually, people drill holes in the frame and bolt on roller blade wheels or something. The thing is, I don't want to drill holes in my frame, so I was thinking about building a moving platform to put the rollers on. I was figuring on making rectangles of 2x4's. A 22"x22" square for the front end and a 22"x36" for he rear to fit the middle and rear legs and then put both on casters.
Since I like things to be usable for multiple purposes, I thought it'd be nice to essentially make furniture dollies so I could also use them to move things around later if I needed to. To be useful as dollies, though, the casters would need to swivel (if I take that functionality away, it becomes simple to build something). At the same time, when the dollies are on their tracks with the rollers on them (and me on the bike on the rollers), I don't want the wheels to turn, just go back and forth if I stand up to start sprinting or something. Coming off the tracks would be bad, so I'd need to lock out the ability of the casters to swivel. Also the casters would need to be able to hold ~50 lb each to be functional as dollies. Just to hold the 2x4s, the rollers, the bike and me, they wouldn't need to hold that much, but like I said, I'm trying to make a multifunction thingy.
Anybody know of something that might work? My google fu must be lacking because I can only find casters with brakes, which are not what I want.
