    Subject: Re: entry step and does anybody have a spare...
    Well said, Kevin. As for your comment that such a repair could be completed in an afternoon, that is true if the covering finish was dope or PolyTone, which can be wiped off with a rag soked in MEK. If painted with latex or Polyurethane, the paint must be sanded off and that takes a loooooong time (ask me how I know!)

Those permanent fixtures are just that, permanent. The vast majority of builders cover them as Jack has. Take a look at www.westcoastpiet.com at the dozens of close-up photos there, including Jack's beautiful airplane. If you end up having to access covered fittings then yes, you're responding to a significant issue of some sort. We don't routinely "snug" structural bolts under fabric. If you do have to get to a covered bolt to do work, you cut the fabric, do the work, and then make your patch per the instructions you'll get with whatever covering system you use. The fabric portion of those repairs would likely be completed in an afternoon.

    Subject: "accepted inconsistancies" poly fiber pricing
    The info below is pasted from the Poly Fiber FAQ section. While this certainly includes fabric, tapes etc, based on the now $70 or more per gallon price of Poly Fiber products, I'll bet it would come in "around" $1500, give or take. Of these systems, which is cheaper? How much will it cost to cover my plane? If you got a price quote on each of the three systems, you'd see that they all total about the same. Only the cost per can is different. For instance, dope costs about $35.00 a gallon, Poly-Fiber is about $60.00 a gallon, but you need twice as much dope as Poly-Fiber. The urethanes can get as high as $200.00 including catalyst and flex agents. Here you use fewer gallons, but at a much higher price. No matter which system you use, the final cost for the fabric, tapes, coatings and paint is about the same. Cub sized airplanes will cost $2,500 to $3,000, depending on the color you choose. Ultralights run about $500 to $1,000 on average.

    A few years back, I weighed a few wire wheels that were at Brodhead, plus I'm on my third set (don't ask) myself. 16 to 18 lbs seems the norm without the brake assembly, just the wheel, tube and tire. Douwe

    Subject: Re: Wire Wheel Build-up
    Here is some more detail on my wheels. (As I see this is becoming a hot top ic.)- My rims, as stated, are 21" X 2.15". The actual rim width measured at the edge of the rim is 3.00". The 2.15", I believe, is down inside the r im where the tire bead lays. (I have not verified this.) The rims are alumi num as are the nipples. The spokes are SS. As you may have noticed, I did n ot opt. to have anything polished. (I even preferred the spokes to be dull, but they are what they are.) Highly polished rims/nipples won't match the look my plane will have. I MAY try to dull the spokes with some sanding... My hubs are all SS. Flanges are 3/16" thick and the tube is 1.5" SS tube. T he ID of the tube needed to be machined larger ever so slightly to accept t he bronze bushings. (Press fit)- The overall hub width is 6.0"- Kennie recommended going no smaller then 6" for strength purposes for cross-wind l andings. As noted, Kennie was fantastic, customer service of the likes which is rare in today's age. That alone was worth some $$ to me...and well spent. You can have any of their Sun rims drilled to any number of holes and you m ay have anything polished to a chrome like finish...all of which will cost you more money.

    Subject: Covering Processes
    From: "K5YAC" <hangar10@cox.net>
    Wow... these darn snow days are becoming very educational. I didn't want to hijack Douwe's discussion on the cost of covering, but since the topic is being discussed, I have a few questions. I honestly haven't done much research on covering materials. I've made comments to others like "I'm going to use the Stewart System and latex paint", but I really don't know what I'm talking about where these materials or processes are concerned. Polyfiber, Ceconite and Dacron are all fabrics, right? Are there more? I have heard that MEK is nasty stuff, which is a key ingredient in at least one of the processes. I know there is also a need for a respirator with some of this stuff, so I've been leaning towards the Stewart System since I've got a 6 year old hanging around me most of the time. Same goes for latex paint, I've heard that it is not only cheaper, but easier to apply and people have got good mileage from using it. Someone on here has had a panel hanging on a fence post for several years, right? The only information I've got on covering is the Stewart System DVDs, which are nicely done and make the process seem very straightforward. There is an outfit in Arkansas (Aircraft Fabric & Finishes I believe) that came to our EAA hangar for a covering workshop a few years ago, but I missed it. Some were talking about having them back... perhaps we'll be able to arrange that this year... you listening Mr. Markle? Perhaps someone can point me (and others) to a more comprehensive comparison of these products and processes. I know that the search feature is available, but not knowing the difference between a fabric or a process it becomes difficult to make sense of the different topics that might be found. Having a little better base of information would probably go a long way in understanding some of these covering discussions. Perhaps there is an "intro to covering" write up out there that covers the different fabrics and processes for those of us that have never done this stuff?

    Or, you could use the latex method using Stewart system glue, like Gary Bell, me and others have and come in under $1000....with no fumes at all.

    We are going to do the fabric very soon. We got the price from Aircraft Sp ruce for the materials then took those prices to a local supplier at our lo cal air port. I asked them if they could be competitive price wise item fo r item. They bid the materials at a lower price than Aircraft Spruce and t hey pick up the shipping. The shipping on hazardous materials like paint i s a real consideration.

    Subject: keeping costs down, and NX799B progress
    I heartily concur with what has been mentioned earlier regarding shipping. Shipping really adds up over time to the point that it'll really surprise you. If you're wanting to be as frugal as possible, try hard to order large batches of stuff at once, rather than two an3 bolts because you ran out, or another quart of reducer, or six inches of hose, or, or , or, or. I've found it difficult, if not impossible for me (being a first time builder) to predict exactly what I'll need, so even though I try hard to get everything into a big order, I invariably items out which I then MUST have the following week, making UPS my biggest fan. Finally getting some traction out here. Cowling and new grill coming along nicely (will send pics when a bit further) and new wheels/brakes and landing gear almost done and working out very nicely. This is my third set of wheels I've built, second one with brakes. First set had one wheels torqued in the accident, so new ones were in order. Because they're inconspicuous, I like a drum brake with the hub built internally into the wire wheel. First time 'round I used go cart bakes as some others have, but after some more searching, I found some brakes from golf carts which are very nicely made, larger and sturdier than the others, and so far they're working out nicely. Like all drum brakes with large wire wheels, they will most likely be underpowered, but that's good since everybody's gears are now too far back. :o Did a cool thing which I'm also really happy with. The flat backrest really became uncomfortable after twenty minutes of flying around my shop, so I cut out a 15" square and replaced it with a carbon fiber piece that has a contour in it. In the deepest point, it protrudes behind the bulkhead about 1.5", so it'll move the CG back a tiny bit, but being only 150 lbs, I'm not worried, and the difference is huge. I did the same with my seat bottom to drop me down into the pit more and to try to match the contour of my bottom. $ .02 Douwe

    I agree Douwe. Although I've got a long way to go, I know that I've already spent several hundred dollars on shipping items (including two freight trucks). Aside from planning ahead in order to get as much as possible on each order, one of the more helpful things that many have mentioned is the "Bag of Spruce". I ordered this early in my project and I'm glad that I did... I've used these scraps several times. Another thing that I would like to recommend to anyone starting out in this hobby from scratch (as I did) is a "Homebuilders Hardware Kit", or something similar. Having this selection of common hardware has saved me a lot of guesswork when mounting fasteners. Of course, taking accurate measurements helps when planing assemblies, but sometimes it is nice to hold stuff in your hand and know that it will fit/work. This also keeps me from ordering a handful of nuts and bolts as I need them. As I use stuff up I can just replenish my stock when I place an order for other things, not ever time I need a fastener. I'm fortunate that there is a lot of hardware, tools, materials and knowledge readily available at my field and in the Tulsa area, but I can see how these little things can really start to rack up for people who are in more remote locations, and even for myself when I fail to plan properly. -------- Mark Chouinard Wings, Center Section and Empannage framed up - Working on Fuselage Read this topic online here: http://forums.matronics.com/viewtopic.php?p=329477#329477

    Great point about a starter set of hardware. Does one exist? Various Google searches have resulted in dubious results.

    There are several hardware kits at various vendors. I purchased the Homebuilders Hardware Kit from Aircraft Spruce. Go to the link and click on the "Assorted Kits" link... there are many. I purchased this one as I figured it would cover much of what I needed. They also have this one, which is nearly 3 times as much and contains way more than I'll probably need. -------- Mark Chouinard Wings, Center Section and Empannage framed up - Working on Fuselage Read this topic online here: http://forums.matronics.com/viewtopic.php?p=329488#329488

    Another option is to wait until final assembly to buy and install AN hardware. For now, I'm using inexpensive hardware store stuff -- to date, I've probably paid close to $10 total on this stuff. One advantage is that I can use the cheapy stuff to let me make a detailed inventory of the exact lengths of AN that I'll need. I figure I can place one order for everything I'll need when I know exactly what that will be.

    I saw it a while back when I stopped by for a visit....and the pictures don't do it justice...it's pretty amazing really.... It was interesting to see the weather beaten test fuse Rick built when he first started. It's sitting outside on the ground near that fence post with the test piece. The fuse has also been out in the elements and it's looking tired! But the paint test piece hanging on the fence....like new. That made for an interesting contrast.

    5 years? Awesome! Kevin Purtee offered me a quick lesson on covering offline. I was confusing the materials and processes with trade names and visa versa.

    Maybe a stupid question but I can't figure it out (what's that say about me ??) Where do you start the leading edge plywood from? If you start from the bo ttom of the leading edge=2C how is it held in place while gluing - are nail s used? Or do you start it from the top of the leading edge and sand it in to the curve of the wing? I just don't see anything in the plans for this . Thanks=2C Tom B.

    Tom basically what I did was sheared sections of 1/16 aircraft ply at about 9.5" when installed flush with the back of the front spar the ply will be just back of the arch of the leading edge profile. I stapled the front section with 1/4" staples at about every inch or less. When glue is dry the staples were removed and the leading edge sanded smooth to blend with the profile. Hope this helps and is probably better illustrated by the attached photos. -------- Adrian M Winnipeg, MB Canada Read this topic online here: http://forums.matronics.com/viewtopic.php?p=329534#329534 Attachments: http://forums.matronics.com//files/dsc00381_107.jpg http://forums.matronics.com//files/dsc00376_697.jpg

    I installed 1/4" x 1/4" basswood backing strips with T-88. Removed the nails after the glue set. This gave me something to glue and nail the LE material to. -------- Mark Chouinard Wings, Center Section and Empannage framed up - Working on Fuselage Read this topic online here: http://forums.matronics.com/viewtopic.php?p=329540#329540

    Subject: Re: Covering Processes
    Not so fast, Dave! Your work is definitely exceptional, but I question the statement that "... there is not much uv protection in housepaint...". Almost all paints contain Titanium Dioxide...the same Titanium Dioxide used in sun block. House paints would have to block UV if they were to protect wood. Benjamin Moore Exterior Aura brand paints describe their UV protection as "Extreme." Rhetorical question - How long should one leave the fabric on a wood framed airplane, no matter what dope/paint is used?

    Subject: Re: entry step and does anybody have a spare...
    Thanks, Kevin. That will make my life easier when it comes time to cover the fuselage. I will study the Westcoast Piet site before I do anything. Nice to know the fittings do not need to be snugged up after construction. Thanks for the help. Also thanks to Jack for his reply. The wheels I have are 19X2.5 and weight 12 lbs each WITHOUT the tire and tube. the poor old Sky Scout would end up either very nose heavy, or earth bound! Thanks again.

    Subject: Re: wire wheel weights
    I measured and weighed my wheel today. It is a 19 X 2.5 wheel, steel, chrome plated with very heavy spokes (either stainless or chromed, did not check), the axle hole diameter is 1.25" with nice brass bushings. The hub is 7.5" wide. The wide hub plate is at least 6" in diameter with 4 holes in each side..... would take a brake nicely. The only problem is, each weighs 11.5 lbs without the tires and tubes! They look expensive! I think these would be way too heavy for the Scout, right? Maybe I could find some aluminum rims for the hubs? Forty spokes, 3 cross pattern.
