For instance, in the 'Hawk chat room we've hit the subject of tubing fit for welding, but we haven't mentioned fitting finish (not while I've been listening, anyway) and how important edge finishing is on fittings and how to do it. Computers have made it easy for newbuilders to tap into the experience others have.

I am more convinced then ever to build the Bearhawk. In fact I've ordered the 4 Bingelis books, taking advantage of the special for EAA members, and am planning on contacting Mr Barrows in February- March time frame to get my plans. This leads me to my question, I was able to download all of the AC43.13-1B(Aircraft Inspection and Repair) from the FAA website and supposedly AC65-15a is there too, does anyone know if it is on-line somewhere. I'd like to take advantage of what the webs got to offer. Thanks again for this forum, I am definitely going to tap into this wealth of experience. Hope to be one of you soon! +++ #954 Subject: AC65.15a....FAR 65.15a From: Tim Cramb At Landings....; Under FAR there's a 65.15a but no AC in front.

Not much there - it was started today. However, I have MANY pictures to add showing construction techniques and progress on Bearhawk 023. This is going to be my builders log - nothing fancy. Disclaimer - I am not a web page expert! This page will not have fancy graphics. I spend most of my time building airplanes not working on web pages. I will be making updates weekly if not daily. Again, nothing fancy just practical pictures and techniques. You will have to endure pictures of my family . . . http://home.fuse.net/wjohnson Notice the picture of the tail leaf spring and modified spring attach bracket. Off to build the elevator . . . +++ #1836 From: William & Delinda Johnson Subject: [Bearhawk] Thoughts & Best Practices More pictures added to the web site - enjoy. Some thoughts and best practices: 1. I am using swaged cables since I have access to a swaging machine. It is a good idea to put a small amount of red paint where the cable enters the swaged fitting. Will make inspection for cable slippage easy. See picture: http://home.fuse.net/wjohnson/Mvc-860f.jpg 2. To mount the lead mass for the elevator, I welded .032 metal sheet on the top and bottom, melted the lead, and pored in the slot with the elevator nearly vertical. See picture: http://home.fuse.net/wjohnson/Mvc-843f.jpg 3. When mass balancing the elevator, account for the weight of the fabric, tape, stitching, dope, paint, etc. I did this by stripping some fabric off a wrecked citrabria elevator (only had 8 hours when crashed due to weather!). I wanted to ensure a slight overbalance condition. See picture: http://home.fuse.net/wjohnson/Mvc-833f.jpg 4. Stinson Rudder pedals (just the pedals) work great! Adds a touch of class to the home made assembly. http://home.fuse.net/wjohnson/Mvc-839f.jpg 5. On the flap handle cable attach arm, I made the inside of the arm straight to move the cable toward the center of the fuselage. It gives the cable more room. This is suggested in one of the newsletters. http://home.fuse.net/wjohnson/Mvc-863f.jpg 6. I ordered an tail light bracket from spruce. Here is a picture of the installation from the back side. http://home.fuse.net/wjohnson/Mvc-872f.jpg 7. The linkage to connect the trim torque tube to the actual trim tab needs a bend to ensure clearance. See picture. http://home.fuse.net/wjohnson/Mvc-848f.jpg 8. I use oil holes on all internal parts which need lubrication as done in many Cessna and Piper planes. Piper sometimes even used oil holes externally; however, I prefer grease fittings when exposed to the elements. LPS 3 is great for use in the oil holes and ensures lubrication until the next annual. http://home.fuse.net/wjohnson/Mvc-801f.jpg +++ #1956 From: Mike Eldredge http://home.airswitch.net/mike-and-judy +++ #2446 From: Tom Martin Subject: [OTHER] technical info website I use this at work a lot.

It is an awesome collection of Bearhawk info. Go to http://www.eaa1000.av.org/pix/erbpix/bearhawkcd.htm for all the details. As far as flying the Bearhawk, since Bob Barrows has built (and regularly flies) both of the completed Bearhawks in the world, Bob could give you a good idea of how the airplanes compare. You can call Bob at (540)473-3661. Bob does not have email. The only person I know of in this group who has actually flown both Bearhawks is Budd Davisson. You can see his review of Prototype II at http://www.airbum.com/pireps/PirepBearhawk260.html and he also has a review of Prototype I, which is the same pirep he writes in the October 1995 Sport Aviation magazine. That should get you started. This is a great group of folks, and the excitement is definitely there for one of the best airplane designs in the world. +++ #2703 From: Donald Schindler Subject: Re: [Bearhawk] I did it! Welcome Aboard Bion, to answer some of your questions, a good place to start is to join your local EAA chapter for its resources,and talented folks. Regular brushing of elbows with them will help you keep your motivation; kinda like a shot of adrenaline every month. Buy the Tony Bingelis books; Firewall Forward and the two others available from the EAA. Some of the other guys have said look at the project as not a whole airplane but a series of little projects; that way it is not so daunting a task in your mind. There are numerous articles on tools in Eaa literature and Cleveland aircraft tool is a quality place to buy. Lastly, remind your wife, on a regular basis, that while other guys are out drinking and carousing, she is fortunate to have you occupied at home in the garage building something of great value that can transport your family all over the place.

The mentioned link takes you to and from there the 'Download' entry in the nav-bar takes you to a list of files, several of which sounded kinda' interesting. This particular report is about half way down the list, at the 5/18/00 mark, and is a 650k 'doc' file of 94 pages. With a quick scan of the contents it appeared to be a well ordered collection of things to consider when configuring a cockpit. The human-factors learnings for how to organize the front office, how knobs and levers should operate, and how important it is for them to be consistent. +++ #4133 From: Tim Subject: The Incomplete Guide to Airfoil Usage This has to be the most 'complete/incomplete' list ever, even the Bearhawk is on it, check this link out...> +++ #4135 From: Bob Romanko Subject: RE: [Bearhawk] The Incomplete Guide to Airfoil Usage > This has to be the most 'complete/incomplete' list ever, even > the Bearhawk is on it, check this link out...> > > Thanks, Tim.

I found this by accident using it: http://www.free-ed.net/ Look a little down the page and you'll find "Welding 100" with some "Hey, kids, don't try this at home!" warnings. It may be useful. Now a question: Has anybody heard or dealt with Tiernay Metals? I wrote Landings.com asking if they knew of any European metal dealers and they sent me the Tiernay website URL. I noticed they claim to be the big boys in aerospace technology. I just want to know if they're OK to deal with. They have a U.K. and a U.S. division. Some days ago I found a metals website that had a page dedicated to people wanting to unload a bunch of extra material they somehow ordered in excessive quantities. It made for some curious reading at any rate. (How in God's name do you over-order ten thousand pounds of super-duper widgets?) No 4130 steel or aluminum to mention, but if there ever is you might pick up some very inexpensive material that way. I'll try and find the page at some point again and let you know if they have anything interesting for builders.

Therefore, I present for your enjoyment some updates on #164 on my Bearhawk web page http://www.eaa1000.av.org/pix/erbpix/erbpix.htm Down in the middle of the page you will seen pictures of the horizontal tail, the top frame of the fuselage, and the bottom frame of the fuselage. Currently I'm working on the jig for assembling the top and bottom of the fuselage. Just like anything that requires aligning large pieces, it is progressing slowly and deliberately. I've found no reason to try to rush it, because it seems to take just as long either way and it's less stressful that way. We haven't done this for a while, so I call on the assembled Bearhawkers to give an update on your project. budd and Mark can tell us how the kits are coming. Planter Bob can tell us about his house. Russ Erb >>> 20may03 #11298-18250 +++ #11503 From: Ken Beanlands Subject: Northern Pilot. I just got my copy of the August/September Northern Pilot and found a very interesting article on this funky new airplane. I don't know if the rest of you have heard of it or not, it's called a Barrows Bearhawk ;-) Very cool article. Too bad that OTHER 4-place, homebuilt bush plane made the cover. Sure enough, the Bearhawk and Moose articles were back to back inthe magazine, but the articles certainly painted a much rosier picture of the Bearhawk than the Moose. The Moose article seemed to dwell on teh utilitarian features of the plane and the procedures required to start the beast. The Bearhawk article focused on the kick-in-the-pants performance of the 260 hp plane and how well it performed. Sorry Budd, but they directly compared it to the "much-vaunted Cessna 180" as beintg it's equal ;-). They did have some confusion about what the "optional cargo door" was. They suggested that the stock plane had 3 doors (two in front and one for the rear seat on teh RHS) and that the cargo door was only the back half of what we call the cargo door. They did give a lot of coverage to Avipro as well. I have to tell you, I love this magazine! They have just as much on homebuilts as they do on production stuff. The other interesting article was a blurb on teh new Lycoming IO-390. It's a bored out IO-360 producing 210 hp. That would be a great fit for the BH. I wonder if it's possible to get the IO-390 jugs for an IO-360? Ken Beanlands B.Eng (Aerospace) +++ #13834 From: "gmgdls" Subject: DOD/specification website Thought I'd share this w/the BH group, the information I've seen shared over the last 4-6 months here is amazing. When it's my time to build I can and will use your experiences and information to ease the process. I've noticed there have been questions and concerns regarding processes or hardware which BH builders seen to be looking for information about. The following website (paid for and maintained with US taxpayers dollars)can be of value. I was given this site address 5-7 yrs ago by a DER which I worked with on a type certification project. Keep in mind the US govt is getting out of the doucmentation business, thus many are getting cancelled, inactivated or turned over to private industry (ANSI,ASTM,ISO,ASME,SAE etc...) Here goes - www.dsp.dla.mil click "online specs" click yellow text "Quick Assist Search" w/ blue globe in the background. Now you have (3) choices - Choice # 1 has never been much help for me Choice #2 - If you know the spec or std document # type only the number - for chemical conversion coating (at times referred to as alodine) type 5541 (for Mil-C-5541), or 8625 (for anodize Mil-A-8625) etc. for hardware like rivets type 20426 then enter. Choice #3 - Type the word rivet or screw or what ever you are looking for and then enter, you will get hits w/in the govt documents where the word appears in the title. Try screw - 150 hits for mil spec screws of various type and or material. I saw the issue today or yesterday in the discussion group about square-head drive hardware searching this site might produce something. These specs and stds provide you with technicial data regarding dimensional criteria along with material, finishes and in some cases performance. You can then view the document in acrobat reader, for the document listed as current, some historical documents are still available. NOTE: you cannot get industry stds (ASTM's)off this site. This is one of several govt site where you can find out how many beans are to be in a 12 oz. can of mil-spec pork and beans if you knew the spec #. Or wanted to make military type bras. Also listed are what is called QPL's (Qualified Products Lists, if you were looking for a specific manufacturer of a product like Mil-P- 23377 primer you can find who the manufacturer is, not that you can necessarly buy from them, but you know who makes it) The maufacturer will usually give you a distributor. I have never used much else on this site -but- there is a wealth of info available brought to you with your tax dollars. Use the site for what it's worth, and hope it help's.
