I just picked up an all-steel set for occasional use, from craigslist for $45.
These are about as crude as you'll find and look like you could make something similar if you had access to a machine shop.
Since I ride in the Winter, they're acceptable quality for the use they'll get.
They feature formed sheet steel side rails with lightening holes and large dia. seamed steel tubing rollers with end caps that hold the sealed bearings. The front roller is adjustable by moving the protruding bolt ends (possibly threaded rod?) within slots along the side of the rails and tightening the nuts.
Due to being seamed tubing, the rollers wobble very slightly and they ring like a gong when you tap on them with a knuckle. They're also loud in use.
For limited use, you could probably make something like these. For regular use, I'd really consider buying a better set.
