Mark do you mind sharing the cost of the related materiel and equipment? As Ken mentioned what precautions do or should you take, inclosed area, booth of some type. Can you recover and reuse the blast materiel?
I am guessing that system will really show where the rot is and how deep it goes.
They all look clean. A part of me likes it while the other says " what about the patina". Patina includes bat guano et cetera. Such is life. Tim

I had someone come in and do the tests. The cost is 75/hr plus material, and this is a low hourly amount, as it is a friend who has just gotten the blaster. He said 100/hr is more like it. I don't know the cost on the material, or media as he called it.
This means the cost will depend on the finish you are going for and the person running the machine, and how organized you can have your timbers laid out to work on.
The guy running the machine had a full suit on and a full face respirator. I would think the best way to do this finish is outside, before raising...

I'd shy away from the glass bead, and go for the walnut shells or corn cobs. They're more people friendly and tool edge friendly.

In log building cob blasting is pretty common. I saw one builder question blasting potential "bug food" into crevices. Don't know if that's a legit concern or not. I've heard of dry ice blasting but have never seen any, no cleanup.
I've used an osborne brush in a right angled drill as one more technique for the files.

btw, it's corn cobs(ground), not corn grain that the blasters use around here. There would still be potential bug food, but much the same as wood.

I've been away for a few days. Thanks to all for the information. I'll pass it on to the folks concerned.
