DIY dolly track: WHEELS

[vonkuttenberg]

hello, i am wondering about wheels for my DIY dolly (dolly base carrier and rails are not so hard to make) but i am wondering if there is any way to get some U shape wheels like those professional...

1) does anybody have found some usable U shape wheels to buy as mentioned down in the article?

2) what about using wide skate wheel as possible and "digging" U shape?

3) what about using two skate wheels next each other in opposite to classic DIY 90° angled skate wheels ( http://cinevidproductions.com/Media/DollyShots/DollyWheelDetail.jpg )

4) if i will use last variant of 90° angled wheels, is it possible to use it on rounded rails or for this purpose need to be done second dolly track?

VAR A) SMALL TRIPOD RIDE WHEELS

VAR B) BIG JIMMY JIB WHEELS

Found V groove wheels. They would run on a 90 degree metal angle. Here is a source. http://www.cisco-eagle.com/catalog/...e-iron-wheel-roller-bearings-800-lbs-cap.aspx and http://www.castercity.com/vgroovew.htm

Anyone with a lathe can make those wheels out of some plastic/nylon round material.

P.S. are you really from Kutná Hora?

All of those casters cited in the web pages are designed to work with straight angle-iron "tracks". They would likely slip off the typical PVC pipe "tracks" that most DIY dollys use, particularly if going around curves.

The most frequently seen solution is to use a pair of modern roller-skate wheels attached at right-angles to an angle-iron like this...
