The...Yes my own work is producing related results. The Mastech MS6252B is a much nicer unit (USB output is a real boon for work like this) - but vane-type anemometers are problematic. The good ones sample once per second. The poor ones sample less than that. The pace of a bellows has a minimum driven by its design (the flap-valve must be kept closed) but that runs 60-90 beats per minute. So to model the changes in the flow requires a higher sensitivity than any vane-type anemometer I have found.<br /><br />A pitot tube type or a temperature differential type is likely a better choice. The Omega HHF1001A will do 4 samples/second which does seem better than most.<br /><br />I do think though that the float tube with a visual reading from video (allowing 30 samples/sec) is where we need to go but the floats I am working with need to be sub-1g in mass which is problematic. More design is required<br /><br />My talk is 3pm on Mar 29 at EAC (and will be posted on youtube and will remain up there after the conference).

Is it possible to send me these illustrations or can you tell me the way to get them,<br />Indeed, I am going to build a medieval bellows for a reconstitution of a forge dated 1340. I have not found any illustration from this period which shows a large bellows (two stacked chambers).

I demonstrate this with any IR remote control. But, due to variant materials in lenses, and the fact that no one typically worries about IR sensitivity, you may get random distortion of colour rendition - might explain the purple of the cell phone camera. <br /><br />IR cut filters are available for some devices, you could try one on the SLR.

I was invited on the show with a message that read almost exactly as yours did, and I don't even forge blades. A casting agent saw a picture or two of my knives on Reddit and sent me a message. I seriously doubt you got anywhere with your email because casting agents aren't exactly affiliated with the show, and they probably don't care about the ins and outs of it. They're just casting agents. Their job is simply to find people and get them to apply.

Up to 200 men were employed prior to the closure of the blast furnace in 1847, following the exhaustion of the LOCAL bog ore deposits". <br />That's 31 years of bog iron...!

It's hard enough to make a handle for one knife. After all this, each of the judges take a knife and and test it with a railroad spike and pummel it with a sledge hammer. Destroying their edges.duh! Then do a sharpness test. Talk about screwing with people. These guys are on a power trip. It will kill.

Here's a working link to his site using that search engine: https://web.archive.org/web/20170508143918/http://jhbladesmith.com:80/<br /><br />Also, FWIW, a lot of Don Fogg's site is still archived there and viewable as well using the same archive search engine.<br /><br />Here is a link to that as well: https://web.archive.org/web/20120227211919/http://www.dfoggknives.com/<br /><br />There are quite a few gems that wouldn't basically be lost in internet oblivion if it weren't for the Wayback Machine so it's definitely a great resource to know of. If you know of any other websites that are no longer being hosted and want to see them again, just enter its URL in the search bar and choose one of the (usually multiple) years/dates that the Wayback Machine archived it on in order to view the site just as it was on that very day: https://web.archive.org/<br /><br />Anyway, perhaps this may be helpful to somebody else as it has been to me.<br /><br />Thanks for sharing the info in your BLOG btw.
