Could I get some advice on working stainless steel and its properties? I want to work sheet and plate to about 1/8 thickness and have found this stuff very tough in the past. How would one drill and cut it with good results in a homebuilders shop? What types of saw blades and drills work best? I...

Looking for a wooden prop for homebuilt. I understand that wood props have certain advantages over metal and composites. A wood prop has virtually no memory and is not subject to fatigue as is metal. Also on contact, a wood prop will not result in as much damage to engine/crank etc. I know a few...

I recently acquired a 114 in dia, 10in blade width antique wooden prop , Paddle blade style with 8 bolt holes. Too big for a Jenny, maybe for DH4, Whats your guess?

To All: The low cost and wide availability of wood in America makes it a good choice for the budget-minded builder of simple flying machines. The only problem is that when picking the stacks at the local lumber yard you need to know a fair amount about wood in order to select the most suitable...

About five years ago I cut and planed Douglas Fir planks for the landing gear of my Fly Baby, but we moved before I got them glued up. I'm finally getting back into the swing of things. Should I re-plane them to get a fresh-cut surface before I glue them?

There are many homebuilts that have open truss type wooden fuselages built from square spruce sticks joined with plywood gussets. Typically the gussets are 1/8" plywood. Aircraft such as the Cavalier, Termite, Pietenpol. Somethings bugging me .... When it comes time to cover the fuselage what is...

I'm looking to start a home built aircraft. Does anyone have any suggestions on which type of lumber to use that's a good alternative for sitka spruce? Thanks

http://www.publiclumber.com/2x4sitkaspruce.html Anyone had any dealings with them? They sell "aircraft/spar-grade" 2x4 spruce for $4.50 / lin.ft. Their prices on marine ply are about what I can get locally, but the price on spruce beats most I've seen. Of course, it's only a good deal if the...

Those of us who fly behind (or in front of) wooden props usually reduce RPM significantly when entering rain. I reduce RPM to 1900 in rain, or I see minor damage, despite the urethane leading edges. For me, 1900 rpm results in a rotational tip speed of about 400 mph. This doesn't consider the...

I'm working on the center section for a Hatz. The trailing edge of the center section is a recurved lamination that provides better access to the front cockpit. I've steamed and clamped the strips into a form, and they have taken on some of the curve, but when I unclamp 'em after they dry, I get...

In my effort to learn/remember/practice correct building procedures,I monitor several wood aircraft design sights. In the emerauders group,much discussion about using a wingspar that was built and purchased by another builder. The Emeraud spar consists of 2 laminated built ip beams,w ply...

Hiya Came across this smart SE5 WW`1 look-a-like homebuilt last week in Norfolk , UK. It is a Wolf W-11 Boredom Fighter - recently restored back to flying condition and is the only one flying in the UK - thought I would share this image of it with...

I just acquired a WW-II Wobble pump(D-2) and would like to make a handle for it--can anyone steer me to a picture of one WITH HANDLE ? I have already broached an 8" length of 3/4 SQ aluminum to fit the shaft---I'd just like to make it similar to an original pump handle. Thanx Jerry

Wish I'd have built this one. Although the ads on the video are a pain in the afterburner. Flash

Hey, Jim, think you could improve on this a little?? I know there's a lot of new stuff that's not on it-- Have at it...Jerry

I continue to see a lot of requests for avionics schematics, wiring diagrams, etc on this newsgroup. Since I have my own web server, I will volunteer to put together a "library" of these things if there is enough interest in it. To do it, I will need you folks to send me your diagrams that you...

Would anyone be kind enough to point me to a wiring diagram for a general aviation radio? I need to know the pinout configurations and voltage for the mic connection. Thank you and regards in advace! Gary

It just seemed to me that a 2-letter prefix would hasten the search for a particular wire without going through 100-200 Numbers only
