Overview

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.

Metric Ordering Information
Spruce can be cut to metric sizes upon request only as special order, non cancelable and non refundable.
Using our current part numbers please select one size greater than desired and at check out in "Special Instructions" advise exact metric dimensions needed.

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

For additional technical information refer to a complete reprint of spruce specification MIL-S 6073 and plywood specification MIL-P-6070.
P/N 13-14900

Faster Delivery can be assured if guidelines regarding minimum acceptable lengths are provided. Orders are often delayed awaiting delivery of lumber to the even footage specified whereas shipment could be made if the minimum usable lengths were indicated. Example: 3/4" nominal 6" x 12' (131-1/2" min.)

Please order by part number and also state exact thickness and width. Begin part number with “02”, then thickness & width. Example: 1/4"T x 3/8"W is P/N 02-1438.

great quality, and the order arrived quickly!!

Douglas B

Appreciated how well the product was packaged for shipping to prevent any damage. Great product and it arrived in pristine condition (not always the case with other vendors whose product I oftentimes receive crushed because no care or forethought was put into how to best protect it from rough handling). Was also pleasantly surprised that my order arrived far quicker than projected.

I received this wood as a replacement for wood that was damaged (I presume in transit). The replacement wood is good quality though I note one side has two areas of impact damage clearly not from transit as the box was in very good condition. This area will be cut away when milling the parts so I can use the wood. There are quite a few rules behind aircraft grade lumber and I would prefer Aircraft Spruce (AS) be more careful in their milling and handling of the wood. I give AS high points for quickly replacing the damaged wood.

Several of these are not usable. The grain is not good and they will break when bent just a little

Delivery was delayed several times but the spruce arrived eventually and it is beautiful - top quality.

Quality product as always. Only four stars due to shipping time. Realize I place relatively small orders but still takes awhile. Generally worth the wait!!! Claudia is the best, always good communications.

Product as stated, well cut only had a few that were a bit twisted but was no problem to correct. Will be buying more.

Q&A

Q: Do you stock long lengths of capstrip?

We mill it as necessary from lengths of 20+ feet. For complete stock information, please call 877-477-7823 during usual business hours or email us by clicking here.

Q: I'm ordering 400ft of capstrip. If I have it delivered, how long will each section be?

You will need to provide the cutting instructions upon checking out. For practicality and shipping purposes, we recommend cutting down to sections under 5 ft. UPS Ground will take sections up to 8 ft, but at that length shipping charges are more due to dimensional weight. Sections over 8 ft will need to ship via Truck and shipping charges will be significantly higher.
