Thanks Paul but it's still a lot cheaper and easier to make your own I think. All you need is to buy the wood for a few pounds and cut, plane and sand it a bit. It doesn't say how long they are on the site.
Krank - Thanks but my ply is not very thick so I'd prefer to use bolts. It doesn't need to be thick because it's not a large sheet.
I was thinking of making some sloper campus rungs too. What's the best angle that will be challenging but not impossible for campusing? I was thinking about 35 degrees from horizontal. How thick should I make the sloper surface? I guess about the length of my middle finger?
I was thinking about pinches too. I guess this would be like thick campus rungs orientated more vertically. Does anyone have a good picture showing a campus board with a variety of wooded hold types?
