I agree Jack. I did the same thing. Hated to sweep up those shavings. Shapingthat and the tailfeathers was some of my favorite parts.Don EmchNX899DERead this topic online here:http://forums.matronics.com/viewtopic.p ... __________

For a Forest Lab chart of wood strength go here;http://clifdawson.ca/Tools_and_Tips.htmlAll usable woods for AC application have plussesand minuses but in the end aren't that much differentfrom each other. You can't just look at the wt/cubic footor, strength for the same dimensions, of different woods.Spruce's advantage over Doug Fir is mostly ease of workability, no pitch pockets and it doesn't split as easily. Hemlock is actually a little lighter for the same strengthbut the grain tends to be a bit wavy and it's much harderto find dimensioned lumber. It's mostly cut into molding.One of the strongest woods is Lodgepole Pine but I'veyet to see one with any length of clear trunk!The leading edge does not provide any "spar" strength,only toughness to resist things like hanger rash and fastflying bugs.Clif I used Sitka Spruce. Best strength to weight ratio of any wood. Jack Phillips NX899JP ________________________________________________________________________________Date: Fri, 5 Dec 2008 05:45:21 -0800 (PST)

Just a thought, Tom=85have you tried drilling a hole (same size) thru a blockof Oak (at least 1 =BD=94 thick), clamp hard to the frame, and maybe it willhold the bit where you want it? You may have to start with a small hole(same set-up) and increase to your size.I=92m using that method on all my holes for the metal fittings on the fuse.Gary BootheCool, Ca.PietenpolWW Corvair ConversionTail done, working on fuselage (endless metal parts!)(12 ribs down=85) _____

That's a good start. Now go get a long bit. It will be bendy.The block will hold it straight and the length between the drilland the block can be bent by holding the drill at the requiredangle to force an arc in the shaft.I've got 3/16" and 1/4" ones 12" longAnother option would be those bits with 1/4" hex ends. Plugthat into one of those bendable screwdriver extensions.Clif Just a thought, Tom.have you tried drilling a hole (same size) thru a block of Oak (at least 1 =BD" thick), clamp hard to the frame, and maybe it will hold the bit where you want it?

In addition, you can use a 1/4 inch chuck with a hexagonal spline. The spline willfit into the flexible shaft extension. Keyless chucks are available at HomeDepot for only $4.50.Rick Schreiber----- Original Message -----
