Thousands
of feet of S2S aircraft quality spruce are
stocked in our Corona, CA. warehouse. Orders for spars, spruce kits
and capstrip can usually be shipped within three weeks after receipt
of order. Spars wider than 6" must be milled from 8" specially selected
stock which requires a long and indefinite lead time. Prices on request.
Spruce and tubing kits may be combined with plywood
and other building supplies for a single truck delivery charge.

only certified aircraft grade spruce. Do not accept lower grades
of spruce for lower prices in your project. It is no bargain.
Demand top quality. Capstrip may be cut from "C and better" graded
spruce as it is a nonstructural. No Packaging Charges on Spruce

General
Ordering Information
Aircraft spruce spars are
available either S2S (surfaced 2 sides, top & bottom, with rough edges in
4" & 6" nominal width) or S4S (surfaced all 4 sides to thickness & width).
Prices in table below are for S4S spars. If S2S is desired so builder can
trim to exact width, specify S2S and use 4" or 6" width prices from table.
Request quote on spar widths wider than 6". Spars for certificated aircraft
such as Aeronca, Stearman, Taylorcraft and Piper are available and may be
priced from the table. Since many of these early aircraft were “handmade”,
the spars are often not uniform in size for a particular model. Therefore,
the finished net dimensions should be specified when ordering replacement
spars. Please price to nearest fraction.

| |
| |
When ordering either spars or capstrip, designate the thickness
first, then the width and length.
Examples: 3/4"T x 4 1/4"W x 14’L
spar; 1/4"T x 1/2"W x 5’L capstrip
