Thanks for the feedback. I found a whole bunch of old file covers atwork (about 1940-50's vintage that are the same thickness as aluminumand are also very dense (glazed). They glue up well and I am now lookingat butt joints with a 1/2" "gusset"behind. I may yet look at aluminum.How did you fasten? by glue or?________________________________________________________________________________

Yes the 1.5mm aircraft birch I bought was about $24.00 4x4 sheet , Anderson's International has italso Westwind Hardwoods , International Hardwoodsin Detroit has very beautiful okoume 1/16 that is ($50 4x8)marine grade no knots very light and strong, the great thingis that they can be rolled up in a cylinder and shipped ups.all the above can be found on the internet. also Harborsales has very beautiful okoume,sapelee,khaya and birch in severaldifferent widths and grades free catalog 8008689257 I recently found baltic birch plywood in 1/8 and 1/4 in in local hardware store 50"x50" inches for $12.00 a sheet, very strong, failsin wood not glue line, I also purchased hollow core interiordoors that were damaged form a local hardware storefor $2.00 a piece, ripped the edges off with a table saw then slowly pryed apart while cutting card board spacingwith hand saw, not bad stuff left outside a week with a coupleof rains with no delamination. width is about 1/16" A light sanding withmed grade paper will remove the cardboard and gluefrom inside section of ply. I'm no expert but if you ever hadto force land in a corn field I believe the damages wouldbe much easier to repair on a ply leading edge than one builtof sheet aluminum.-----Original Message-----

Hello to the group,i used 1.5mm 3 ply birch for my leading edgecover.Soaked in hot water in the sink for 1/2 hour or so,then was able tostart the ply at the bottom edge of the leading edge and wrap it around andstopped about 3 inches past the spar at the top.I secured it to the wingover night with strips or wood and bungee straps,then removed it the nextday,it retained its shape,then applied epoxy and held it in place againwith the strips of wood untill set.I then cut scallops in the ply betweenthe ribs at the top for visual apeal (to my eyes anyway).I epoxied stripsof high density styrofoam on top of the spar to support the light ply.Ialso cut false nose ribs and epoxied them to the inside of the leading plyto give more support as i found without it,the ply did not lay true.I think if i was to do it again i would consider aluminum,far less labour? I also routed out the back side of the leading edge before i installedit,saving 1.5 lbs.per wing. For what it's worth......Doug Hunt.............

I used the aluminum and think it looks great: smooth, estheticallypleasing. I used epoxy varnish, as you suggest, and then nailed the LEdirectly, just as you plan to do.

The source was old files at work, namely Control Department files thatwere obsolete. They were old filing jackets of very dense (glazed) paperboard that were almost like arborite but not as stiff.in 9 x 12 format.they glued up real well. the trick would be to go to the source and trieto get a stub roll of the stuff before they were cut up. I suspect thatthe stuff is no longer made.I went to the Beaver lumber store and for $9.00 Canadian, got 14" x 10'aluminum flashing. $30 for the whole works.The name of the material that I think would do a good job is;ACCOPRESSGenuine pressboard binderAcco Canadian Company LtdTorontoalso ogdensburg,N.Y, Chicago, londonI went to the local Home Businesss store, but could not find anythingsimilar.
