I was wondering what you are doing for transportation to Columbia. I'm living in Nashville right now and if it wouldn't be to much of a problem i'd like to bum a ride from some one if i could. Also if anyone is interested, i know of a college dorm that is open for the summer, its 8.50 a night. right in nashville. about 6 miles from the airport.

I understand it may not be enough as the project progresses and the need to purchase more individual sizes will arise. Please be informed that although Cad plated and Stainless bolts and nuts are usually graded by the ASME scale, almost none will meet AN specifications. The most noticable difference is that AN spec bolts have ROLLED THREADS and very few if any commercially available bolts thru grade eight including case hardened Allen Socket type are CUT THREADS. The obvious difference is the removal of material during threading for the ASME bolts and the non loss of material for the AN bolts. FWIW folks , the cost of AN bolts over commercial bolts does not warrent the savings in the overall price of the project, but it does eliminate the doubt of bolt failure.

For those that are interested in some real world testing (complete with graphs for you engineer types) on Longitudinal stability, the following URLs may be of some interest. In this case, a real live genuine test pilot did some real honest to goodness test flying with a Lancair 360. In the end, he really ripped Lancair for not living up to their advertising as in his professional opinion, the instability that he saw in the Lancair makes it unsuitable as a cross country machine or a stabile enough to do the pilot justice as an IFR platform. Lancair's answer was to state that it was a matter of pilot training and that no pilot should fly a Lancair with less then 10 hours dual in a Lancair. The second URL is the results of test flying the plane after having a larger tail built up on it. The general gist of it is that the larger tail was a significant help. That of course means that Mike Mims is probably on the right track with the significantly enlarged horizontal stab on his Stump Puller 290.

I have been out of town all week in a training class (learning how the US phone system works... sorta). At any rate I couldn't do much email.

I agree with Bobby Muse, keep it simple and it will work best. I used my Workmate bench/vise and a few large clothespin-type clamps to bond my spar webs to the spars. I glued the scarf joints before I attempted to put the webs on the spars, and that worked out great. So far, nothing new here. But what I did that I haven't seen metioned is once I had spread the epoxy on the web and spar and got them positioned together the way I wanted them, I layed the assembly on the table, web side up, and put waxed paper over it. Then I put one of the other spar pieces on top of the web, sandwiching it between the two spars. I took the whole assembly, centered it in the Workmate, applied moderate clamping pressure, and then used clothespin clamps on either end of the spars. This resulted in a very uniform bond that didn't squeeze out too much epoxy from the joint and left the right film thickness. Plus, I didn't have to pull all of those staples (I did one side of the forward center spar with the staple method). Once the epoxy was cured, I just took off the clamps, cranked open the Workmate, and pulled the "clamping spar" and the waxed paper from the finished product. Worked great! A couple of caveats/requirements: 1. The face of the spar caps and verticals must be perfectly flat (or nearly so) for this method to work. Any irregularities in the spar face will create voids between the spar and web. You may be able to use some flox to fill any obvious low spots before you put the web on. 2. The webs also must be perfectly flat, especially in the area of the scarf joint. I sanded mine flat and then vacuumed them to remove the sanding dust from the pores of the wood. If I were to do it again, I would buy another Workmate, put them end to end, and have a more uniform clamping pressure the length of the spar.

(Jeffrey E Scott) Subject: KR: RF Noise filters...Success A couple of weeks ago Paul Bittengle of Orland, FL ("mailto:LngDistRep@aol.com" ) put a post to the KRNet asking for volunteers to test a noise filter he has been considering selling. Since I have been having a terrible RF noise problem in my plane since day one, I volunteered to do some testing. I am using 1946 vintage Eiseman Magnetos with Bendix "P-lead" filters and a Terra TPX 720 handheld radio mounted into the panel with a copper strip antenna moulded into the vertical stab. Up until I installed Paul's filter on my radio, it has been an RF noise nightmare using the radio. It appears to be a simple in line filter and was quite simple to install. My first impression was that it wasn't doing anything as all the RF noise sounded the same as before. But, when I flew in to Santa Fe for the airshow last weekend, I started turning up the squelch until the background noise was squelched out. In the past, this would have left me only able to hear radios with very strong carrier signals that were very close to me. I often was not able to talk to other planes I was flying with. On this first flight with Paul's filter installed, I was able to squelch out all of the background noise and was still able to hear all the other traffic in the area as well as Santa Fe tower. I now have four short flights in and out of lots of tower controlled traffic with Paul's filter installed on my radio. It has allowed me to enjoy my plane even more without the constant roar of RF background noise in the headsets. Thanks Paul!
