Uhh, you should sand the ply to remove any release agent they use in manufacturing. Oh and glue an eight inch of squeeze out is good. Excess epoxy adds weight to the build fast.

I am sure that Pientenpol didn't use Epoxy, i know of casien & urea formaldehyde glues being around in the forties, but before then it was hide glue,

Cool👍🏻 go on👍🏻😍👏🏻👏🏻👏🏻

Матрица для изгиба полок нервюр мне понравилась. А вот технология обрезки книц на нервюрах не самая лучшая. Я предпочитал сразу вырезать кницы какие нужно по размеру. I liked the matrix for bending the rib shelves. But the technology of trimming the gussets on the ribs is not the best. I preferred to immediately cut out the gussets that needed to be sized.

Nice. I'm probably going to regret this since I don't have any woodworking experience, but I've decided to build a Pietenpol. Thanks for your videos.

SWEEEETT!!!!!

Does the front of the wing get installed when the gussets get installed?

Great sounding engine!

You are very accurately measuring the wrong glue ratio --- T-88 is 1:1 by volume not weight .

PUT THIS WOOD OR CARDBOARD UNDER THE STAPLE TO GIVE SOME SPACE UNDER THE STAPLE TO GET A TOOL UNDER IT.

Hey all, I know this is an old video, but if you're using as a reference, the ratio between hardener and resin is only 1:1 if measured by volume. If you're going by weight as in this video, you have to use a resin/hardener ratio of 100/83 per the T-88 spec. Hope that helps!

Did this plane ever get finished ?

I'm looking for a set of heads !

Succinct and we'll explained. 👍🏼👍🏼👍🏼

WHAT AIRFOIL IS THAT?

how is this pietenpol doing? flying already? more videos?

Excellent series!

How did you handle installing the leading and trailing edge pieces?

titebond III is just the ticket. Not affected by moisture, acids, gasoline. Wood joints always break at the wood instead of the glue joint. So easy to apply and easy cleanup.

I would like very much to communicate with you about your rib building. Are you available somehow? Thanks, Brian

where did you ordered that plans from???

That engine definitely sounds healthy.

I have been reading the comments and see several takes on this process. One thing I would like to bounce off you is what type of glue was used in original production. I'm sure it wasn't epoxy that had to be applied to not miss one millimeter of coverage. I have even seen someone calling for a glue that is "vibration" rated as if there is one. If you choose to go to the lengths that you do too satisfy your heart than so be it. Just a note if your gonna be anal about it you should not deform your gussets with staples as it breaks the fibers in the ply demonstrated by the raising and splitting of the fibers. A simple weight or block and clamps is more than sufficient. Very fastidious, thorough and quality work though. It is your plane and and as long as you are having fun you can rub it anyway you want as they say.

Is the form that you are clamping to for the top of the rib or the bottom? I noticed that there is another former in the background with a more severe radius on what would be the leading edge, what is that for? Also, if you are soaking 8 spruce strips I presume that 4 will be for the top and 4 for the bottom of the rib? If so, what former do you use if any? Apologies if these are dumb questions. Regards Paul

You're a Great Master... thanks.

I built a fuselage onto a 20 foot long table. I made the frame from 2x4 's and the top from particle board. I was told not to trace the plans onto the table because the plans can shrink, so I just drew them onto the particle board.They said to be sure to put wax paper over the table before gluing the parts together. Particle board is hell for strong, but too heavy for airplanes.

Why not just form the spar to match the contour of the inner part of the rib, that'll add structural integrity by having one part and no filler.

Great video, do you have any more showing the fuselage or any other part of the plane

Very informative. I am using an idea right from Kenny Crider's Piet's wing jig and I plan to also use circular disks instead of the square ones the plans call for. In this, I'll be omitting the staples (I just don't trust them). I know the plans call fo nails, but Bernard pulled them for the reasons you stated. Nice video! Thanks for posting!

can i use home depot wood to do it. thanks

I'd love to one day build 1 of these airplanes. it would be so much fun to do and be free in flight.

Interest stuff that T88 epoxy. I think its a 100/100 mix by volume and a 100/83 by weight (resin/hardner.) I've never used it (T88) myself. I always make some test pieces in fiberglass or epoxy to eliminate weird stuff going on (expired date catalyst or whatever.) Thanks for posting this. Once when reworking my sailboat hull I mixed up a laminate panel with acetone (polyester) that didn't get hard. Interestingly it could be bent and shaped and later brushed with resin/++hardener to make it hard.

why not use foam material?

I'm so HAPPY you didn't put music on this video! :D

Ok, how are you going to get your wing ribs over your spars, when your spar box frame is already put together? Do you have to take the whole !@#$% wing apart if you break a rib, take all the wires and everything else off, and slide all the ribs off until you get to broke rib, and slide it on ?

All my wing ribs just fucking disintegrated, from transporting my uncovered wings on a bouncy trailer. At the moment, I hate wing ribs. Indestructible, my ass... ! About as snappable as chopsticks... a 2 year old could break these stupid things. It's going to take me forever to rebuild this wing now. There has got to be a better, faster way to build stronger wing ribs. www.eaa.org/en/eaa/aviation-communities-and-interests/homebuilt-aircraft-and-homebuilt-aircraft-kits/resources-for-while-youre-building/building-articles/wood/making-wood-wing-ribs Aren't you compromising the wood grain integrity by jamming staples in there? Why not use lead weights on top of them until they dry? Also, you don't show the gussets getting trimmed off... what do you use, a bandsaw? And where do the peanuts come into the build process? :-/

I like your video Do you have an e-mail to contact

Nice, but how heavy/strong is this compared to a plywood rib? Wouldn't the latter be much quicker to make also? Nice work btw!

any guy who builds guitars, mandolins AND a Piet is OK with me!! See my Piet data plate on ebay. Brian

Great video, looking forward to getting started building my ribs. The T-88 mix ratio of 50/50 is by volume. The ratio by weight is 100:83. systemthree.com/products/t-88-structural-epoxy-adhesive

If you use TiteBond II for your wood gluing; all of it. there's nothing to mix; no wasted time; and the wood will break every time before the glue line breaks; as has been proved over and over again. In other words; this is a mis-guided attempt to build something to "Aircraft Specs.". Glue is glue; and wood is wood, and when the wood breaks before the glue does; there's not much left to talk about.

Three wonderful videos.... Really hope to see more!!

thank you!

Great to see the little details of building. Nice presentation style, easy to listen to. Thanks.

im glad i found this channel as myself im building a piet at 17 also im planning a piet flyin at flabob

Some good little tips in there that I might use with my Piet build. Keep it up!

Well done. Will stay tuned...
