Hi JoJo, I believe that what you're referring to is "Cobblewood floors". Just go back out to the FAQ section and you'll find it. Oh, what the heck, I'm in a good mood so here's the link; Cobblewood Floors.

Wick!

I saw the same tip on tv and it also caught my eye. here's another link you might enjoy. http://www.juellfloors.com/home.html They manufacture cobblewood flooring, but it is outrageously expensive.

Can you saw any wood to make tiles or do you have to buy expensive tiles?

I'm curious as well. I saw a "do-it-yourself" installation in a store in Denver. They used reclaimed Douglas fir and Pine. I don't know where they heard about the process (they hadn't seen Bob's show!), but they cut all the wood themselves, about 5,000 tiles for a 900sq' space.

MY questions are:
1)Are any woods preferred? ... & new or old?
2) Can it be used outside (covered or uncovered?)w/pressure treated lumber? I'd like to use it in a covered entry porch.
2)How economically can I produce this floor myself?
3) Is it cost-effective to have a local millwright cut the tiles?
4) Do I need to use a floor leveling compound before I install on a concrete slab?

I live in the Phoenix area. Are there any local resources? Thanks for any help you can offer.

I have the same question (and more!). I saw a "do-it-yourselfer" installation in a store in Denver. They used reclaimed Douglas Fir and some Pine in random sizes and cut approx. 5,000 tiles for a 900sq' space. Their grout was sawdust & linseed oil, which is VERY combustible if the mixture is left alone for even a few minutes. As the store owner tells it, the mixture started to smoke when she left to take a phone call. I don't know where they found the process, since they hadn't seen Bob's feature. I'd love to use this in my remodelling, but I have more questions.
1.Are any woods preferred? ... and is new lumber OK?
2.Can I use this outside, either in a covered or uncovered area? I would like to extend the foyer floor out onto a covered entry porch. Is pressure-treated wood an option?
3.Do I need to use a floor leveler on a concrete slab? How should I fill seams (or expansion joints outside?
4.Would it be cost-effective to have the tiles cut by a local millwright?

Thanks for any help you can offer.
