aviken,I have attached a snapshot of the page in the AC 43.13_1b that discusses the variousproperties of wood. As you can see from the chart, poplar is not a directsubstitute for Spruce.Also, I am attaching a link to a downloadable copy of the AC 43.13. You can downloadthe entire reference, and it will answer many, if not most of your questions.That is not to discount the knowledge of many of these experienced builders(I am certainly NOT in that group), but it gives you a ready reference atyour finger tips as opposed to asking and then waiting for an answer.http://www.faa.gov/documentLibrary/medi ... ----Semper Fi,Terry HandAthens, GARead this topic online here:http://forums.matronics.com/viewtopic.p ... ttachments: http://forums.matronics.com//files/scre ... ___Subject: Pietenpol-List: prop finish

Construction is progressing well. Five ribs built and turning out about 1.5 perday.I am reviewing the supplemental plans and laying out fuselage sides.On the extended fuselage, how does one determine where the "cross struts" (go betweenthe sides) are located?No dimensions for these on the supplemental plans that I can see. With the addedlength the dimensions from the original fuselage clearly won't work. I cansee where two inches were added in the first and third bays but this does nothelp locate the struts. I would think these locations are critical as they determinelanding gear, lift strut, cabane, etc attach points.What am I missing?ThanksGrant ZiebellSavannah, TNRead this topic online here:http://forums.matronics.com/viewtopic.p ... ___Subject: Pietenpol-List: Re: prop finish

thanks for all the great responses and pictures. makes it exciting to wait on thething to get here- not sure just what stain to use or even what wood theyare using o cut it from-should have asked earlier on. but when it gets here I'llhave a better idea of how to go with it now.

I actually asked him what he might have that was most affordable- he had 2 propscut sometime back stored way for Corvair engines. I wanted to stay with straightblades and get a few more inches pitch than my 66X29. he had a 32 or 33 anda 34 pitch. I think both as in the rough were about 72" long. he sold me oneworth the money and I will most likely cut it to around 68" long to start with.maybe even 70" if it looks like it will clean up well there and balance out.and can trim length if it proves to load it up too much a little at a time.since I fly from a pretty short and very un-forgiving strip I don't want to gettoo aggressive with pitch, but the one I have just gets me out really wellbut immediately have to throttle back quite a ways to avoid over speeding andI want to do little experimenting with a second one.Read this topic online here:http://forums.matronics.com/viewtopic.p ... ___Subject: Pietenpol-List: Re: prop finish
