Sawing VERY hard wood

Fla._Deadheader · September 22, 2006, 09:25:27 PM

Actually, it's petrified. Got any ideas ??? :

Furby · September 22, 2006, 09:35:38 PM

There was a thread around here someplace...........
Might be worth more in one piece though.

You might have to go to carbide tipped blades if the wood is that hard. Expensive but worth it in the right application. Just my 2 cents worth!

Fla._Deadheader · September 22, 2006, 09:46:14 PM

Too big and heavy to move. Might get 24"+ table rounds from it. 8) 8)

USE Carbide blades. This stuff has turned to STONE. :

;D ;D

Remington also makes Diamond edge grit blade that will cut stone but it might not work in your application.

Furby · September 22, 2006, 10:09:20 PM

Ooh, ooh, I want one! I want one!
Got a chunk about 3' long left as a log?
Any idea about shipping it up my way?

Here's the link I was thinking of, you had the answer before you had the question! ;)

A diamond chain saw blade. Its a friction blade that is water cooled. Saw one once that a sub used as a wall saw, but i never saw it used. They might make them that will dry cut.

if it is truly petrified, find somebody who knows something about cutting granite... wonder if petrified wood moves as it dries

I think Duall sells a diamond grit edge bandsaw blade. I've used one to cut rock and they work great, but very slow. The blade speed is more in tune with metal cutting than wood cutting and a lot of water is used to cool/lube. The blades aren't cheap so you might be better of taking it to a marble shop.

I am going to win the dumbest answer of the year award for this but how about having metal cutting bandsaw blades on your bandsaw mill . I mean if its as hard as steel just pretend its steel . I bet the metal cutting type is of higher tensile ? My cousin is always cutting metal and wood on his bandsaw . Why dont somebody make a bandsaw blade that will cut metal and wood ? Never have to worry about tramp metal ever again. I suppose it would cut down on the selling of blades ?

We went through $600 worth of masonary blades trying to cut some for my fireplace. Finally gave up.

I thought you was in CR, not up on Axel Heiberg Island at the fossilized redwood Metasequoia glyptostroboides forest. :D

You get a piece of rawhide strip, kinda like a shoestring. Pound a bunch of sand into it. Pull the strip back and forth across the big rock. Add sand as needed.

Fla._Deadheader · September 23, 2006, 08:34:51 AM

The mill I am building would be able to handle the piece, I think. I'm going on 2nd hand info as to the size of the piece.

It is a Bandmill, soooooo, A band of some sort would work. :

8)

Guess my first question shoulda been, what's Table slabs or Table "cookies" worth from petrified wood ??

Nobody ever find the info on the guy with the WM, sawing rock ???????????

Not pertinent to this thread, but, I was just perusing some Classifeds last night, and noticed our favorite Dentista now has the biggest and best collection of WALNUT in the World, all for sale :

I had a friend that had a petrified log that was uncovered in a large flood about 2 years ago. We looked into it and found that there was a supplier of diamond bandsaw blades and we were planning on using the woodmizer on idle with the blade engaged and massive water cooling. (garden hose)

However due to funds and some other complications this plan never materialized and the log is still sitting next to the river. If you try it I will be very interested in the results.

DanG · September 23, 2006, 09:30:19 PM

Throw the DanG thing in the rock pile and cut something you can make some money on.

Furby · September 23, 2006, 09:36:47 PM

Send it to me!

UNCLEBUCK · September 23, 2006, 09:56:22 PM

There is a place I trucked by south of Holbrook ,Arizona and it may have been located on the Holbrook Indian Reservation but it had truck parking and was quite a big facility and all they did was saw petrified wood , they had petrified wood crafts and gifts and they had petrified wood laying and hanging everywhere . If someone googled it I am sure as large a place as it was they must still be in business. It was on the highway straight south of Holbrook going down towards the salt river canyon ,the old back way into phoenix . It was north of the salt river canyon and south of holbrook , only place I have ever seen anything like that . Petrified City ?

Butch · September 23, 2006, 10:05:07 PM

Petrified wood is cut with diamond blade saws. Gem and mineral clubs usually have them.

Furby · September 23, 2006, 10:09:19 PM

This place UB?

Harold, check out this one:Link

UNCLEBUCK · September 23, 2006, 10:36:32 PM

Good job Furby ! 8) Looks like no shortage of bids for the stuff too

Furby · September 23, 2006, 10:38:56 PM

All small stuff on ebay though. Really want something bigger and Harold has the right idea. ;)

Kcwoodbutcher · September 23, 2006, 10:43:05 PM

Forget about using a bandmill with any kind of metal or diamond blade. Even at idle the blade speed would be to high. I think a good speed is in the 100 fpm range.

Fla._Deadheader · September 24, 2006, 09:11:08 AM

Got any 'sperence to go with that info, Kcwoodbutcher ??? Can't believe this would not bring some big bucks from these pieces???

SwampDonkey · September 24, 2006, 11:59:35 AM

Harold, maybe our new member Gustavo from Argentina has some idea. Here is a post where he mentions cutting some hard woods in Argentina.
