    Anybody an expert on casters?

    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.

    I think I understand what you're trying to build. Here's how I'd do it:

    Build "furniture dollies" to support the rollers.
    Build frame to hold dollies while rollers are on them.
    Use/create a channel to put the dollies' wheels in, so that they can only roll forward & backward. If the channel is deep enough, they should stay in place and not pivot. It's impossible for any of them to pivot if they're "locked" into the channel.

    There are locking to stop them rolling , casters . the channel track will stop them from going off that line.

    Yeah, I've thought about going that way. Trying to figure out how to make the channels. I think I know how I want to do that. Just need a bit more lumber than I'd originally planned. Right now, I use the rollers on a pair of 15/16" 2'x4' plywood sheets. If I get a third sheet, I could cut it into strips and screw it down to make a channel for the casters. The problem is that I have to make my rolling platforms 22" wide and the boards I'm using now are 24" wide, so the strips on the outside would only be 1" wide. Should be cheaper than the angle iron I was planning on putting on the outside of the boards to act as an outer bumper.
