    I guess you are right Jack. The plans don't say specifically. I can't recal l ever seeing the bolts uncovered, but then again I never looked for it. I would think it would be evident on pre-flight inspection if the not had wor ked loose. Not likely in my opinion. And the fabric/paint/glue might serve to hold the nut on. If the concern is the difficulty in covering/fitting ar ound the mounted horn, I can see what you mean. I cut a thin piece of manil la cardboard to fit snugly around the horn at the base and glued it in plac e. This served for a gluing surface for the fabric. Worked quite well.

    Actually Matt I just carried the video equipment around for the film maker so he felt obligated to put my name in the footnotes. :) I really didn't fit into that movie at all but it made for a nice diversion among all the warbird restorers! Adam was very kind to include me in that film. Mike C. (don't look me up on the Post Office most-wanted list....terrible photo;))

    Using the thoriated rods, a full time welder will be exposed to less than 100 millerems of radiation in a year. Another web source says a welder is exposed to 16 millerems a year. We naturally absorb about 300 millerems a year by just being here on planet earth. The occupational safety limit is 5,000 per year. A radioactive iodine solution to treat a thyroid will expose you to 10,000,000 millerems of radiation. I wear a dusk mask when I sharpen them. I found these numbers on the internet so take them as you may. -------- John Francis Read this topic online here: http://forums.matronics.com/viewtopic.php?p=394624#394624

    Subject: Axle Threading / TIG Welder sources, rates
    Group, I have no idea where to find someone / company to thread my axle (straight axle LG) - or to do some TIG welding (not including my engine mount which is already done by Vern @ flycorvair.net ) you know - all the control pieces, etc.. some questions: 1. Generaly what company 'type' am I looking to google / yellow page lookup for this service? 2. What should I expect to pay (generaly) to have the axle ends threaded? 3. What is the going hourly rate (range..) for a GOOD tig welder? If anyone in the greater dayton-cinci-columbus OH areas has a refferal for either or both types of services, Id appreaciate that also. .

    Subject: Shoulder Harness
    I am considering putting shoulder harnesses in my Pietenpol. Does anyone have any ideas as to the best anchor point for the shoulder harness for the rear seat? Also what hardware have you found best to mount to the structure? Thanks, Joseph

Generaly what company 'type' am I looking to google / yellow page lookup for this service? 2. What should I expect to pay (generaly) to have the axle ends threaded? 3. What is the going hourly rate (range..) for a GOOD tig welder? If anyone in the greater dayton-cinci-columbus OH areas has a refferal for either or both types of services, Id appreaciate that also. .

    Well, I think I'm gonna have whomever wants to come to my place to help me with my hangar/have fun/do some machining and play with stuff in either two or three weeks. I have a very nice TIG welder and we can do some/all your welding. Or we can have my neighbor do it as a demo (he's a lifelong professional welder, formerly ASME certified to TIG weld cracked nitrogen tank cracks). We can also thread your axles as long as the axles are 1 1/2" or smaller (that's the size of the through hole on my larger lathe). So consider coming down to Chatt for the weekend. I should have beds, couches, cots, motorhome, floor space for 15 to 30 people, no worries there. Should be the weekend of 2/3 Mar, or the next weekend. If there's any interest there for you, let me know, I'll post details. Insofar as finding local help, really, try Craigslist for welding services. Many pros advertise there to make a few bucks afterhours. Otherwise, just google or yellow pages. Typical "shop rates" are gonna run 75 an hour probably, unless you can work a barter, strike up some personal connection or something like that.

    Subject: Shoulder Harness
    There is a lot of discussion on seatbelts in the archives. This is the information I have about the British seatbelt locations (Same information as the one Mario sent) http://westcoastpiet.com/seatbelts.htm If I was being obsessive about this design I don't like the asymmetric pull on the bolts for the harness. I would rather see a metal fitting coming from the bottom and top that you attach the cable onto. Many people run a 1/8th inch cable from the tail wheel spring fitting. This is how I did my shoulder belts for the back seat. http://westcoastpiet.com/images/Chris%20Tracy/new_page_3.htm I combined both the British anchors and an anchor to the tail wheel in an attempt to divide the load like I do when I am rock climbing. Hopefully I will never find out if it worked.

    you may also consider picking up a oxy/acety setup real cheap (harbor freight) watch some you tube videos and give it a whirl. not super hard. just practice a bit. torch welding isn't as pretty, but does a real nice job. worse case senario, your not happy with your quality of work, have someone else do it, and keep practicing so you can do your own welding on your next Piet. If the cost of a professional to tig weld is much more than torch welding, go with the torch welding. Only thing that probably needs to be tigged on the piet is the aluminum fuel tank. Some will probably disagree. -------- Paul Donahue Started 8-3-12 do not archive Read this topic online here: http://forums.matronics.com/viewtopic.php?p=394636#394636

    Little plug for Air Venture (Oshkosh)... there's a GREAT seminar on GAS welding aluminum (as in for tanks) that is really really good. Very comprehensive insofar as even construction methods that are conducive for gas welding one together. I agree that getting a gas outfit is probably the most comprehensive. You can cut, braze, heat (for either fitting or taking things apart), weld (steel, alum) and solder. I do believe it's probably harder, but in the end, the trick to learning welding is a matter of time with the hood down so to speak. So may as well just learn what your gonna use.

    Subject: Re: Covering control horn bolts, yes or no
    If you are concerned then you could use castle nuts and cotterpins. I am involved with the repair of a wingtip on our RAA club Turbi. As some of you know, it's a low wing AC. The underside two ft in from the tip hit a rebar sign post without sign that was just off the side of a certain country runway, ripping a slot from behind the LE to the first half of the aileron. The man doing the actual repair, being somewhat older, decided the wing had to come off. It's one piece just like the original Piet. FOUR hour job. The four 1/2" bolts holding the wing and fuse together along with a number of other equally important but smaller bolts all had nyloc nuts on them. NONE of these had been touched since this plane was built FORTY years ago. All were fully tight. I know this because it fell to me to climb head first into the bloody thing to remove these things. :-) So in non moving areas it appears nylocs work OK. Just make sure they are NEW nuts every time. Do not re-use old ones. And no, before you ask, it wasn't me who hit the rebar. I don't even fly this thing as I have an arrangement with a friend and his 46, 90hp Chief. Clif I will beg you for advice, your reply will be concise, and I will listen very nicely and then go out and do exactly what I want. I guess you are right Jack. The plans don't say specifically. I can't recall ever seeing the bolts uncovered, but then again I never looked for it. I would think it would be evident on pre-flight inspection if the not had worked loose. Not likely in my opinion. And the fabric/paint/glue might serve to hold the nut on. If the concern is the difficulty in covering/fitting around the mounted horn, I can see what you mean. Dan Helsper Puryear, TN Not sure where the plans call for covering For the horns I would guess being able to make sure they are secure is a good thing. Appreciate all the comments!
