Great video and beautiful pietenpol. Odd that the Ford has the original Ford A water pump builders often use other pumps as the model A pump has issues that even the antique car people have problems with. The packing gland is problematic and the pump bearing don't hold up well. Stainless steel Speed queen washing machine pumps are often used here in the US. Might not be as easy to find in Sweden. The sound of the Ford powered pietenpol is music from a simpler time. Thank you!
MrTomadevil made an 8inch section of the leading edge out of hardwood, then made a female mold out of composites, then put sandpaper in the mold, then rough cut the leading edge on the table saw, then finished by sanding span wise on the leading edge pieces with the mold
The rib is about 30in long. You can buy Pietenpol plans here: community.pressenter.net/~apietenp/BHPietenpolAndSonsAirCamperAircraftPurchasePlans.html The Pietenpol is mostly made of spruce wood (which they don't normally sell at Home Depot).
Soak the top and bottom rib longerons in water over night. A 1.5 inch diameter, ~4ft pvc tube capped at one end, stood vertically and filled with water was used to soak the wood as necessary for this build.
This question may not apply to airplane building but could you simply make the ribs say 3 or 4 times as thick plus the saw kerf for ripping them into 3 or 4 different ribs? I'm saying instead of using half by half inch wood use half x 2 1/2 inch and built one extra thick rib and after the glue sets use your bandsaw with a tall ripping fence to get a total of 4 ribs with the extra 1/4 inch going to sawdust. I know you'd still need to glue each little gusset piece to each connecting joint but is seems you could make an entire wing quicker this way. Anyone please jump in and show me if it wouldn't work. I'm now getting close to a point in life where I'd enjoy building a plane from yesteryear and trying to get all the know-how I can. I know ultralights are more Simple but to me they have very little character.
Phil Lowman I don't see any reason you could not use the method you're describing to make the rib profile core, but you will still need to attach gussets at the joints as shown here, because the gussets provide the majority of the sheer strength (keeps the joints together under loading).
Brian Rieger Yes. I seen the little gussets we're the main strength to hold them together. I'd like to soon start a build a soon but doing the same parts over and over drives me nuts. Like in a machine shop getting a job of making the same part drove me nuts.
@@coburnlowman BUT UNFORTUNATELY REPETITIVE CONSTRUCTION IS PART OF BUILDING A HOMEBUILT AIRCRAFT. AND IT INSURES EVERYONE IS BUILT EXACTLY LIKE EVERY OTHER ONE. I KNOW I HAVE ORIGINAL 1933 PLANS, I BUILT A 1/4 SCALE ONE EXACTLY THE WAY THE REAL ONE IS BUILT. AS OF RIGHT NOW WITHOUT COVERING OR ENGINE MOUNTED I HAVE 918 HOURS ON THE BUILD. BUILT THIS SCALE JUST TO MAKE SURE I CAN BUILD A REAL ONE. WHEN AND IF I EVER GET BOTH FINISHED I WILL DISPLAY MY R/C QUARTER SCALE MODEL ALONG SIDE MY REAL ONE.
