Before you order - CLICK HERE NOW! for shipping schedule & product availability. Plan ahead -  These projects cannot be completed successfully in haste. Allow enough time for shipping, transit times , and careful construction and testing. We do our best ship orders which specify 1- or 2-day delivery on the say we receive them, but we do not guarantee it.  

     The supplies needed for competitive boomilever and tower building events are few and straightforward. Balsa, with its high strength to weight ratio, is the wood of choice. All substructures must be made up of strips no larger than .25" x .25" (cross-section), which makes wood purchase simple.  Any width or thickness of substructures laminated from this basic component is permitted. Wood may be sanded to allow for more or less thickness where needed for optimal strength/weight distribution. 
Tip: glue is much more dense than balsa, so extensive laminations may be disproportionately heavy. 
Tip: Balsa varies considerably in its density, i.e., weight per unit of cubic measure. Each piece should be weighed to determine its suitability in a particular part of your structure. 
Heavier = denser = stronger.  Use the heavier pieces in areas requiring the most strength.
NOTE: there is no reason to use species other than balsa, which has the highest strength/weight ratio.

BALSA -    

We now offer two grades of Balsa:
1) Medium Density Balsa: 10-19 pounds/cu.ft 
   
(maximum range of densities expected in any given lot)   Piece-weight is calculated by dividing
    sheet weight by number of sticks/sheet. Not individually weighed.
2) High Density: 19-28 pounds/cu.ft (maximum range of densities expected in any given lot)
     Pieces are individually weighed.  Higher strength and greater stiffness.

ASSEMBLY SUPPLIES AND TOOLS: 

Grip Pins  - a real necessity!   More expensive than T-pins but sharper and much easier to use.
     These make the job easier, produce better quality work. Two structure sides can be duplicated, one one top of the other with wax paper in between, for symmetric structure precision. Also provides light clamping pressure for setting glue joints at any angle. Use the pin shoulders to hold the work, or pin through a piece of scrap used to press the work to the workboard.  Gentle side pressure can be applied to keep joints in place while drying, and substructures can be held vertical with 1 or 2 pins on each side.  Note: Use very light pressure on parts and do not pin through balsa.  We suggest using an accurately flat, sufficiently large, soft balsa or pine board or piece of 3/4" softwood plywood, clean, flat heavyweight corrugated boxboard, 2'x2' ceiling tile, or dense insulation foam board as a construction surface for use with these pins. Cover work surface with wax paper to permit easy removal of finished assemblies. 
#587 - Grip Pins . . . . . . . . . . . . .$6.50   (Box of 50 pins)    

Ambroid Cement
The choice of many experts. It is very forgiving, and can be removed from an incorrectly built joint with acetone. Apply sparingly with toothpick or balsa sliver. Where weight is critical, do not follow tube directions; apply to one part only.  Where strength is more important, apply to both parts, rub into wood and remove excess, allow to dry a few minutes, then reapply to one part and mate surfaces. Hold in place until dry with gentle pressure with pins, rubber bands, or paper clamps. (NOT SOLD SEPARATELY)  
G18AMBR  1.8 oz tube Ambroid Cement . . . . . . . . . . . . . . . . . $3.25    
The manufacturer of Ambroid cement has temporarily discontinued operation.  This product will be available on an as-available basis.  WE MAY SHIP EITHER DUCO OR AMBROID IN PLACE OF THE OTHER, DEPENDING ON WHAT IS IN STOCK. 

We also recommend a similar cellulosic solvent-based glue, that old standby Duco Cement.
This is the same strong, reliable glue we were building models with 50 years ago. It's a little thicker than Ambroid, and can be cut with a small amount of acetone to adjust viscosity for lightweight structures such as airplanes.
(NOT SOLD SEPARATELY) 

G62455DUC  DUCO CEMENT 1.0 oz  -- $3.25 --  Quantity
(1 oz Ambroid may occasionally be subsituted for 1 oz Duco, depending on product availability.)

Excel Single-edge razor blades         
The experienced modelers' choice. More accurate and easier to control in some applications, and much sharper and smoother-cutting than other products. These blades are also much more hazardous to handle - not for children under 12 years of age. These blades require safe disposal: either wrap dull blades in duct tape or save in yogurt container and cover with epoxy before discarding. 
NOT SOLD SEPARATELY!
