Although the LED's are sealed, the back of the PCB is subject to corrosion, so it probably should be enclosed... you could encapsulate the PCB in some type of plastic coating.

I'm wondering what you (or anyone else) did for your leading edge fillet. >Dan Rondeau Sheboygan, WI ++++++++++++++++++++++++++++++++++++++++++++++++++++++++ I did my wing to fuselage fillets the same way that Jim Faughn did his and it works great. A section of caulk tube or a piece of PVC pipe the size of the fillet you want would also work. As for the lead edge fillet, just block your foam around the lead edge and continue the same process. The trick in making a good fillet is to have two hard surfaces to work to, i.e. glassed wing to fuselage, gear leg to wing and so on. Alway build the fillet after the two joining surfaces are finished. That way you have two surfaces to feather to. If you try to build the wing to fuselage fillet before the wing is glassed you will mess up the wing foam, trust me. Just determine the size of fillet you want, pick a cylinder that size , wrap it with sand paper, and sand away. Your results may vary. I taxied my KR around the ramp and taxiway again today. Yee haa! I sure wish I could find a pnuematic 6" tailwheel to replace that hard rubber wheel I have now but so far no luck. A clerk at the local Rural King store suggested I try a retailer that sells / rapairs wheel chairs. He thought the small front tires on many wheelchairs are pnuematic. I'll have to check it out. When they find out what I want it for they may insist I need to buy the entire chair !!

It seems that sometimes the caliper pistons are put in backwards. This works fine for a while until the brake pads wear down about half way and then brake fluid spews forth, potentially catching on fire if the discs are hot enough (aircraft brake fluid is flammable), but certainly meaning an immediate loss of braking. They recommend that everybody with these brakes check them at the earliest opportunity. Removing the pads and having someone slowly push the pedal until the piston extends out about 3/16" will tell the story. If you see an o-ring, you need to pop the piston out and swap ends with it. If you don't, you're good to go...

Having flown over 160 hours since last November, I have come to the conclusion that flying over my airport (and to/from it) is the most dangerous place to be. I noticed an RV coming in with flashing landing/taxi lights and it seemed to help a lot. The guy markets an inexpensive flasher unit that I bought but have not yet installed. His website is: http://www.creativair.com/exfla/index.htm I also have a Monroy traffic detector and tune to COS approach after getting above the 00V traffic pattern. All this and it is still hazardous. It is amazing that on a cross-country flight in CO you may never see another plane but over 00V with a VOR about five miles to the west, incoming/outgoing traffic, mucho students including USAFA students and you need all options to make it safer. So I would suggest getting the best lighting you can, install a flasher unit if you think it helps. The number of "just a few seconds earlier and...." events has been way too many. Complacency anywhere near my airport in not an option. I bet Red Oak will be a pleasant change.

Are you encouraging a builder to use untreated stock alum as wing attach fittings? Check the archives, there is a ton of information. This comes up a couple times a year but is usually limited to "should I "reheat treat" my WAF after drilling. If you are encouraging the use of untreated, would you please forward to the list your documentation that untreated is better than treated. I don't mean to sound short, but let's not get dangerous.

SUGGESTION. When you post a question, give as much info as possible. Example, the original post simply said " do I need to heat treat my WAF'ings? The question should have included the type of material you are using and the process you intend to use in making the fittings. The original poster needs to try the question again. I know we can build airplanes but after years on the net I'm still questioning our communication capabilities. :-) An for Mark L., the response for all those people asking when will it fly, the response is " all it lacks if finishing up".

That was exacting what I was hinting at in my post. I guess the need to stop hinting and be direct is appropriate. I did a search of the archives for "heat treating". Here is a post from Tracy on this issue. There are hundreds of others in the archives. Heat treating 4130 does increase tensile strength. Now, do you need to harden it? It's up to you. Some have, some haven't. I would. Netters, Since I've been making and selling chromoly aircraft parts for a number of years, I'd like to weigh in on this discussion: My experience with laser cut chromoly parts is that the cutting process leaves an area of hardness near the cut that can only be cut with carbide tools. (I learned this by destroying a new HSS "F" reamer on the 1st hole). The thickness of the material affects the depth of the heat affected zone: the thicker the steel, the further the hardness extends from the edge of the cut. (On 1/4" plate, about .040 from the edge of the cut will be hard). On a batch of axle base plates I had laser cut, I found the heat affected zone so difficult a problem that I sent the plates out for heat treatment before I continued with the machine work. (The center hole in the base plates has to be bored for a press fit with the axle tube and the laser cut surface was so hard my carbide boring bar was bouncing off!) I have gone back to fabricating my axle base plates in-house. I rough them out on a 7" x 12" metal cutting band saw that has flood cooling, then mill them square. The bolt pattern holes are drilled using a drill fixture and the large center holes are bored on the lathe. The axle tubes (7/8" x .190 wall chromoly) are pressed in and then TIG welded. The axle blanks are heat treated to RC 30-34 prior to machining the bearing journals and threading the ends. The threading is done on the lathe. If I was going to make up a set of WAF's one-off, I would have them water jet cut with the bolt holes about .010 undersize and then ream the holes to size. If I were to do a production run of WAF's and wanted to have them laser cut, I'd have all the holes cut .010 under, heat treat the blanks to RC 30-34, ream all the holes to size (including the lightening holes), dress the long edges on my stationary belt sander, and then tumble them! Note: at RC 30-34, you can use HSS reamers and counter sinks, carbide tools are not required. 4130 in the "N" condition has a tensile strength of about 90,000 psi; at RC 30-34 it will have a tensile of 130,000 to 140,000 psi and still be ductile enough to be bent to shape. (That's a 50% increase in strength!) Regards, Tracy O'Brien www.tracyobrien.com Dana Overall 1999 & 2000 National KR Gathering host Richmond, KY RV-7 slider/fuselage Finish kit ordered!!
