What you are describing sounds like a typical cyclone. I would want independent testing before I trusted those numbers. A woodworking cyclone is often advertised as 99% efficient but the numbers are

George I use Leitz exclusively for sharpening, 8 years now and they have always done a great job, I've never had a complaint unlike other sharpeners I've used in the past.? Felder scoring blade ?

Brain, I read Bridge City owner John's post, it says the Gryo Air's design idea came from a Korean engineer and his Chinese partner. The technology is called Axial Centrifugation which makes flowing

This is a good set blade. Anyone who buys Felder slider should not hesitate to ask the sales person to throw in this set plus the scoring blade. It just does not make sense that the new slider does

Yes, I think the Blue Tornado guy was in a car accident and was in hospital for a long time before he died. I talked to his Mother while he was there and it was a sad deal. He oversized his impeller

Leitz, Nap Gladu, Royce Ayr, Guhdo, Leuco, Tenyru, and forrest are all good blades. The sharpener is more important so if the Leitz place sharpens anything you are golden. I have a combination 40t on

I ordered Felder blades. http://us.feldershop.com/en-US/en-US/en-US/Sawing/Saw-Blades/SET-Angebote-Silent-Power-Silver-3-Stueck-zum-Toppreis.html What you really need is David Best's "*Felder*

Death in the family shut it down years ago. IMO they had the best designed fan on the market, the cast the housings and did all the machine work themselves. Brian Lamb blamb11@...

Hello all, I have a new K700S due to arrive next week to my shop. I need to get some blades for it. I got a recommendation to check into Leitz blades from a guy who has a lifetime of experience and

Hey Brian IMHO this is what makes the forum great, we can discuss a subject to death, express an opinion, have a bitch session. I wonder what happened to that company/design. I ?know a lot of vendors

I didn’t mean to start such a back and forth by mentioning a new style DC unit…. but my point here is the dust emitted is most certainly volume when spoken of in mg/m3 and that might not have any

So here is the conundrum, no matter how you want to look at it, whether you're minimizing particle concentration by filter size/type or volume of air you're measuring, what is been done is the removal

My point was not that distribution doesn't exist, but that it can vary widely, including real-world cases where a comparatively larger filter size will not necessarily result in higher mg/m3, such as

"You're presumably assuming a distribution of particles, including ones that are larger than than the smaller filter size. For example, if the source includes 2 micron particles, then they will pass

Not necessarily. Suppose you have a stream of <0.5 micron particles. A 5 micron filter won't let through more of these particles than a 1 micron filter will -- all the particles pass through either

Haha! All good John. I'm full of 95% shit, any advances...? Warm regards, David Dr David Luckensmeyer Practice Manager Luckensmeyer Medical Pty Ltd melissaluckensmeyer.com.au and Designer and

As a newbe I just want to say The information you have provided me so far is priceless, on the other side I like that you all can shovel out the BS too. I had a moment to look at a few of your

Its OK Lucky you can say it, I'm full of shit. LOL [felder-woodworking] <felder-woodworking@...> wrote:

Wow John. Pure entertainment huh? At least 90% of the time? I didn't know you were so knowledgeable. ? Warm regards, Lucky

For some strange reason, elected officials just entered my mind, but I’ll refrain from going any further on that topic. :-) David Best
