Stringers

[Pilot78]

Tribe,
Can someone provide some good pics of the stringers down the sides of the fuselage.....either wood or the aluminum ones? Thanks.

Re: Stringers

Here are some F-19 photos in which stringer attachment appears. Maybe these will help.

Re: Stringers

Norm, those are lovely!

(Not to take anything away from Mark's, you understand!)

Re: Stringers

Robert, Thank you. Attached (hopefully) are dimensions and some photos of stringers that I made. I used a Sitka spruce board 2X8X14 cut into strips then shaped. I checked the attachment, looks like your going to stand on your head to see them, sorry.
Norm

Re: Stringers

That's quite a set-up you have, Norm. I'm envious, because I'd love to improve my wordworking shop to include some of that tooling.

Wood is such a beautifully tactile material to work with, and the shavings smell so much better than metal!

Re: Stringers

OK, didn't find my drawing of the stringer but Norm's look just like mine. I think the top radius was either 9/16" or 1/2" (guess which one is probably easier to find).
If you cut the wood to 2 1/4 wide by 1/2" thick you can route the curve on both ends, then run the wood through the table saw to cut out each flat to make the reduced thickness section. Once the cross section looks like a round ended barbell you just cut the strip down the middle (MAKE A JIG AND SUPER GLUE IT TO THE TABLE! You at least need a little block to support the wood down from the blade.) to make two stringers.
Like I said, I got a nice piece of Douglas Fir that is great for this and you need to look for REALLY straight grain! If it curves off too fast the grain will run out and your stringers will be weak. I don't know if I would use white pine. Too many tiny knots and wide grain. If you can find some old damaged spars they cut up into beautiful stringers!
Hank

If you need really nice wood look at the trim wood at the lumber yard, just stay away from finger joint and don't use Poplar! It looks BEAUTIFUL and works great, but it isn't strong enough for stringers.

By the way, I DID find the drawings for the wood and metal "D" windows. Now I have to find the names for those who were looking for them and find out what they will cost to copy and mail.

Re: Stringers

I built mine out of Douglas Fir. I found a real nice straight grain one. I remember ripping down a 2"x6" and then running it through a shaper and a table saw. Twenty five years later they are still great.

Hank, I'd be interested in your drawings. Please PM me when you decide on a price.

Me too, Hank. Wood Window drawings, please.

Re: Stringers

OK, I'm starting to figure this attachment thing out. Yesterday it took me the better part of an hour to send my pictures, only to have them upside down and sideways. For those of you that are as bad at this as I am, try this on my attachment.Open the PDF file, then view then rotate view.

Hank pretty much made his stringers the same way as I did it. The project of makeing stringers took most of the day to do after I had the 2X8 in hand. It takes time and patience to restore these old Tcrafts. As you all know, you will not save money restoring one of these old birds. If you want to save money , buy one ready to go. I restore these thinga because like most of you,I enjoy doing it. This 1941 BC12D airplane number 6 for me.
