when the cannon fired a 2x4x8' , DID THE wood strike the wall END first ?
Yes, and it was quite spectacular on the unpenetrable walls.
mandatory face shields
Last year I had a backfire on a table saw. It sent a piece of 4" x 3' plywood right into my stomach. I had a 10 " diameter black spot on my stomach for over a week. I do take blood thinners so the apparent damage was somewhat greater than someone with thicker blood. Had it hit me in the face a shield would have helped to some extent. Reporting my experience is really not to evaluate the effect of the face shield but to say that accidents do and will happen, be prepared for them.
triton workshop system respirator
On an old PAPR thread, Airwareamerica was suggested as a source. Very good website, AND they are showing what appears to me (could be wrong....) to be a new and affordable PAPR by Triton called the Triton Workshop System respirator which is supposed to be arriving at the end of March. Helmet/face shield/ear protection in one package for a fraction of the 3m systems. Likely not so able to customize, but it satisfies, if it is effective, the needs of most of us concerned with dusty environs. As a carpenter, this has been an ongoing concern, and at this geezer stage I find myself in, it has become imperative due to dust sensitivity. Funny, it didn't really effect me for the first 50 years....
That does not appear to be a new system from Triton. They are starting to sell the Triton system and replacement parts. I know that the original Triton was uncomfortable to wear and hot because of inadequate air flow. Their second generation system was better, but to me still appears to be rather cumbersome. I don't know much about the airfiltration on the newer model other than it does not any rating. The filter on the original Triton was roughly equivalent to a paper comfort mask.
If you are not interested in shelling out the big bucks for a 3M Airstream, I suggest considering the new Trend Pro model. Several people who I know have one and they say that it is very comfortable (maybe a bit heavy on the head for extended use) and has good air flow to keep the face cool.
Personal comfort is, by definition, a personal thing. I have had a Triton for about 4 years and I find it suitable for pretty much any work I do in the shop.
Airflow has never been a problem for me. As for temperature inside the headgear, if it's hot outside the helmet, no amount of airflow will accomplish much to cool things down. Last summer, I used the Triton to sand a rowing scull I had built. It was up on blocks and I was using a ROS from every angle and I had no trouble with the Triton.
As for the efficiency of the filter, one important aspect of the Triton, in my opinion, is that the cartridge is out of the line of fire (mounted on my belt behind me). That fact alone helps avoid immediate contact with many fines that would otherwise be directed at my face while performing general project sanding, and more related to this thread, while turning and sanding on a lathe.
Bill I have a Triton and can assure you the filtration is far superior to a paper mask. There is an external paper pre-filter on the base of the battery/fan unit and internally two canister filters as used on industrial masks such as the 3M. For the cost, I find it a entirely acceptable product. The original company got caught in the recession and has been purchased and they are gradually getting rolling again. And Art, we at the Golden Horseshoe Guild are trying to enforce mandatory face protection at Hands-on nights and encourage demonstrators to wear them especially when turning faceplate or chuck mounted objects. Many of you may recall there was a fellow killed by a lathe accident in July '09 in Waterdown, ON which is near where I live and ten minutes from the guild. Was not able to find out for sure if he did not have face protection, but have to assume not.
Maybe I am confusing the filter with the original Trend. Is yours the original model from about five years ago? I was under the impression that the original one only had the square paper filter and that the later version that came out a year or two later had improved filtration and greater air flow.
My limited experience is from trying out the original one which had hose problems along with only about 4 CFM of air flow. I believe that the earliest models had a hose that was too stiff and maybe too short. To me, the helmet seemed a bit cramped. A fellow turner bought one and we compared our experiences (I bought the Airstream). He said that in addition to turning, he wanted to use it while mowing to reduce the dust that he was breathing, but it did not work out for him partly due to the low air flow made it too hot and it did not seem to filter enough of the dust.
Mine is about five years old and the original hose was upgraded to the later version at no cost. As far as I know the cartridge filters were always present in them. On hot humid summer days I do find the air flow too low and I am not sure that I could do hard physical work at any time with any one of these. I have used when sawing mdf and the like on the table saw or sanding flat stock. I could not see cutting grass wearing it, ok for short stints of heaby work only.
There are quite a few "reviews" of the Triton that are less than favorable that have been written by folks who don't own them or haven't used them. Many fault the efficiency of the filters and then go on to state that the Trend units offer better filtration.
In fact, both offer particulate and fine dust filtration. The Triton uses 2 RC 64 cartridge filters for fine dust and 1 Washable pre-filter for initial filtration. As far as I am aware, this is the only design that Triton has produced since inception of the product.
