Is anybody going to Broadhead that might have a "Johnson" style airspeed indicatorthat you would consider selling? Or even if you are not going to Broadhead,I would be interested, if you could email me at: charles.w.mcfarland(at)gmail.com. Any condition would be ok as it would be used for a pattern.Thanks,CharlieRead this topic online here:

Gary,Thanks to you as well. I will keep trying to find Pfbeck although his listed emailof pfbeck(at)barnwellsc.com no longer seems to be a valid address.I am pretty new to the forum and the "Piet" world as well, so am not sure whatyou are referring to as far as "certain purists" goes.I also ran across an old post by Kari-Ann Price who sells aftermarket kits.Thanks again,CharlieRead this topic online here:

Charlie,3 yrs ago I was a newcomer, too, and relish those memories of excitement. You arenow amongst the finest group of aviators, near-to-be aviators and aircraftbuilders in the world (present company excepted). However...As a newcomer, you will be allowed only a few transgressions of mis-spelling Brodhead...theHoliest of Holy Places in the Piet community. If you continue tomis-spell Brodhead, in a very short time, you will receive a curt reply from acertain former Marine, reminding you of the correct spelling of Brodhead. Ifthe transgression continues, you will begin to see unwonted items show up in yourmailbox at home...further transgressions will prompt a home visit from saidsurely, former Marine, forcibly reminding you of the correct spelling of Brodhead.He may even have a following of "certain purists", all good, well-intentionedfellows, but serious non the less.Just don't want that happen to you! Hope you make it to Brodhead this year. Ifyou do, please look for me!Gary------Original Message------

Hey Charlie! I'm over here at Gundy's Airport (O38)... home of Chapter 10. I'vebeen working on my project here for a little over two years. Came down toyour neck of the woods a couple of months ago for the Wild Onion and Eggs Fly-In.We were planning to camp there the last couple of years, but the weather...wow! Can't catch a break.You going to Brodhead this year? What about any of the local events?--------Mark ChouinardWings, Center Section and Empannage framed up - Working on FuselageRead this topic online here:

Will do Charlie. Seems that I saw another event listed down there in the Vintagenewsletter. Just wanted to add this so I could help keep the thread on topic.Rogers asked-Does anyone know where I can find some info to build an old fashion Johnson airspeedindicator?Nobody really answered his question. I asked the same question a while back andsomeone very promptly sent me two close-up photos of their Johnson setup (onestatic, one in flight) but I don't remember who it was (black wing struts, yellowwings). Probably Chuck "Baby Oil" Gantzer or Ed Grentzer. I would be gladto send out those photos to anyone who wants them; you could easily buildone just like it by eyeball, along with this narrative info found in the archives:============It uses a .047" music wire, with 2 1/2 coils, and has a leg that is bent perpendicularto lock the coil from rotating, and is inserted into the back plate. The coil is 3/4" in diameter and is spaced off the backing plate with a threadedthru bushing that is 3/8" long. From the center of the coil, to the tip ofthe pointer, is 7". The bushing that is in the center of the coil is 3/8" diameterand is about 3/32" long. The bolt is about a #6, and on each side of thecoil is a plastic washer that is 7/8" O.D. The coil and pivot point is coveredwith a molded plastic teardrop shape fairing, and has a slot cut for the pointerto travel in. The sweep of the arc is 70. The backing plate with theindicator markings is .040 aluminum, probably 2024. The numbers are 20 thru 90mph. The angle plate that the relative wind pushes against is 1 1/4" X 2 1/8"X .030" thick, with the pointer is on the 3/8" leg of this angle, which isnext to the backing plate. To attach the music wire to the angle plate, it hasa small aluminum block that measures 1/4" X 1/4" X 3/4". The .040" wire isdrilled thru length wise, and has two #2 (or smaller) set screws to secure theplate, wire, and block.===============Oscar ZunigaSan Antonio, TXmailto: taildrags(at)hotmail.comwebsite at
