    I looked at the same thing. I purchased some wood from mcmcormick but decided to save it for some of the bigger sticks needed. Ordered enough capstrip to do my ribs from aircraft Spruce last week. -------- John Read this topic online here: http://forums.matronics.com/viewtopic.php?p=317060#317060

    Hi,I cut all my capstrips and milled them.Takes 86 to do the 3 piece wing.I used 1 1/2- 2"x9"x6' rough cut sitka.You loose about half the wood and it takes about 4 hours.Make sure you have the grain laying correctly for a capstrip. -------- Building a Piet Read this topic online here: http://forums.matronics.com/viewtopic.php?p=317063#317063 Attachments: http://forums.matronics.com//files/piet_8_14_10_005_162.jpg

    Thanks to all for your ideas. Couple of things: John - I think you bring up a very good point about the work that goes into making your own capstrip. I may end up using McCormick for all the wood but the cap strip and just order that from aircraft spruce. Dave - I am by no means an expert, but is your grain running the right way? I would have thought you would want it running in the other direction for strength. Jeff - great info. You are the first I have heard mention 5/4 lumber. Was it a full 5/4? Did you get it from McCormick? If I could get 5/4, I would feel much more confident in resawing 3 1/4" sections out of the thickness of the board.

    Subject: Follow up to welding 4130
    Since reviewing the replies on here to my first 4130/SS welding post and looking around on the web, I understand now why welding the two is a bad idea. Most places I saw said then even if welding SS to SS, you should have a professional do it, if possible. (Which I am not) I thought I had heard that you cane weld metals with SS filler, maybe that started the confusion I had with welding SS to other metals. Anyhoo, the short of it is I am square now and fabricating. Thanks for the advice. Michael Perez Karetaker Aero www.karetakeraero.com

    Subject: Re: Resaw Options
    My Piet is all Douglas Fir, but I bought 1 x 6 boards (finished out to about 3/4 in) then planed them down to 1/2 inch, then ripped the 1/4 rib caps. I bought my rib boards at Lowe's over a period of months to find the best close grained boards, and most had horizontal grain. After I cut my strips most had end grain and came out nice. Lots cheaper than ordering cap strips too.

I know I could get 2. Is it possible (for an amateur) to get 3 layers? With the thickness of the band saw blade, and the need to run everything through the planner, I am worried that 3/32" of waste between layers wont be enough.

    From: Kenneth Howe <ken@cooper-mtn.com>
    I haven't gotten the LE/TE material yet. When the time comes I will probably look at the using a piece of molding from Home Despot (or other DIY big-box store) for the TE. It's been talked about here in the past if you search the archives. I'm not sure if the ripped section from a stair railing will work as well for the Riblett LE section as it has for people building the original Piet section. If that doesn't work then I'll probably search the lumber stacks to find some straight grain fir or hemlock and plane it to shape. Use a table saw to rip it close to shape then hand-plane it to the final contour. After finally learning how to correctly sharpen and set up a hand plane a few years ago in a class by a local furniture builder, I look forward to planing the leading edge. What better way to make some parts for your plane than with a plane?

    Hi,The grain should run as shown in the picture.The compresive strength is that way.That is how it is shown in the old CAA and FAA books,Runs just like your spar.Your wing needs compresive strength.I have seen it run the other way and it cracks along the grain lines and the ribs can split.Hope this helps.Dave -------- Building a Piet Read this topic online here: http://forums.matronics.com/viewtopic.php?p=317142#317142

    I did a most of the shaping of my leading and trainling edges on the tail section with a hand plane. I roughed it in close to shape on the table saw, and then finalized it with a small, very sharp and nicely tuned plane and did it in very short order. Probably a lot quicker than trying to clamp everything down and set up a router to to shape the parts. Using a sharp and tuned up hand plane is a very satisfying thing in and of itself, but even more so when using it to build airplane parts! -------- Billy McCaskill Urbana, IL tail section almost done, starting on ribs soon Read this topic online here: http://forums.matronics.com/viewtopic.php?p=317171#317171
