TRACTOR CAB

rucks move America. Tey haul everything from rawmaterials to nished goods in atbeds and tankers. wo typesof trucks provide the power to pull these trailers—the tractorcab and cab-over-engine, which follows this project.

Most of the parts of this truck are interchangeable with theparts for the cab-over-engine truck, so it’s easy to build bothat the same time. Also, the trailers that follow can be hauledby either style of cab. Te main differences between thetrucks are the sizes of the chassis and engines.

Te design of this truck is simple and straightforward, with

a sense of realism. And, by making the base of the truck alittle longer, you can make a variety of intermediate trucks.

PROCEDURE

1. BASE

Cut the base (A) to shape asshown. If you’re making a longertruck for a customized design,continue to use the same wheelcutout conguration at the rear ofthe base.

After cutting out the rearwheel notches, drill the 3/8"-

diameter exhaust stack holesas indicated. Finish the baseassembly by drilling the 5/16"-diameter axle holes through theaxle holders (E, F), then gluingand clamping them to the base.

2. CAB

Glue and clamp together fourpieces of 3/4" × 3-1/4" × 4-1/4"stock to form the cab block (B).

After the glue dries, sand the blocksquare and transfer the cab patternto it. Cut out the cab using a band-saw, scroll saw, or coping saw.

NOTE: Most hole saws will notcut through the 3"-thick stock.

Drill a 1/4"-diameter hole forthe steering column (L); theninsert the steering column into thehole, but don’t glue it in place yet.

(Te steering wheel will be addedlater.) Finally, glue and clamp the

cab to the chassis and check thesteering column to make sure itstill turns. Set the assembly aside.

3. ENGINE

Glue four pieces of 3/4" stock toform a 3" × 2-1/2" × 3" block forthe engine (C). Sand the blocksquare after the glue dries; thenround off the edges according tothe plans.

Using a bandsaw or scroll saw,form the outline of the grill bymaking a 1/8"-deep saw kerf 1/2"from the front of the engine. Next,drill the 3/4"-diameter holes forthe headlights; then glue the lightsin place. Finally, glue and clampthe engine to the chassis. After theglue dries, power-sand the sides ofthe truck ush.

4. FENDERS

Cut the stock for thefenders (D) to size. Ten use a2-1/2"-diameter hole saw andcut the circular prole as shown.Round off the top and frontoutside edges.

NOTE: Tere is a right and

left fender, and they are notinterchangeable. Be sure to markthe edges you’re going to round.

Glue and clamp the fendersto the truck assembly flush withthe front.

5. WHEELS

Make the wheels (G) with a

2-1/8"-diameter hole saw. Before you cut them out of the stock,use a 1-1/2"-diameter hole saw tomake a 1/16"-deep kerf to denethe rim and tire. Next, cut out thewheels using the larger hole saw;then mount them on an arborand sand them. Assemble the

wheels and axles (H) to the truckassembly with glue.While the hole saw is set up,

cut out the 1-1/4"-diametersteering wheel (K) from 1/4"stock with a 1-3/8"-diameter holesaw. Sand the steering wheel andglue it in place.

6. TRAILER HITCH

Cut the trailer hitch (I) to sizeaccording to the list of materials.Drill the 7/16"-diameter holeas indicated in the plans; thenpower-sand the bevel on the top.Glue and clamp the hitch to thetruck assembly.

7. EXHAUST STACKS

Te exhaust stacks (J) arecomposed of two parts—a 3/4"dowel and a 3/8" dowel. First, drilla 3/8" hole through the length of

the 3/4" dowel. o do this, makesure the 3/4" dowel is securelyclamped to the drill press table.Next, glue the 3/8" dowels intoplace. For a realistic touch, add ventilation holes by drilling aseries of 1/8"-diameter holes oneach stack.

8. ROOF LIGHTS

Drill three 1/4"-diameter holes in

a 1/2" × 3/4" × 2" piece of stockas shown. Cut the stock in twoto form the light holders (N).(Save one of the holders foranother truck.) Next, glue the1/4"-diameter lights (O) intoplace; then glue and clamp thelight block assembly to the roof.

9. STEP

Make the step (Q) according tothe drawings. Cut 3/4" stock towidth, then crosscut it to length.Chamfer the ends and sand thepiece. Glue and clamp the step tothe truck assembly.

10. FRONT BUMPER

Te easiest way to make the frontbumper (P) is to form a 3/4" ×1-1/4" × 4-1/2" block of stock withthe proper prole. Next, cut theblock into 1/4"-thick pieces. (Saveextra bumpers for other trucks.)Glue the bumper in place.

Your tractor truck is nowcomplete and ready for a trailer.Roll on to the trailer sectionand build the kind of trailer (ortrailers) you want.

BIPLANE

Te Stearman rainer Biplane was the standard trainingplane for the Air Force and Navy prior to and during WorldWar II. Because the original color of the plane was yellow andso many students scared so many instructors during training

ights, the aircraft picked up the nickname Yellow Peril .Tis biplane design is generic and uses only the general

features of the Stearman rainer. Since special constructiontechniques are required for this toy, read all the instructionsbefore making any cuts. Also, it’s quite easy to make morethan one of these planes at a time.

Here is the ight plan for the biplane.

PROCEDURE

1. FUSELAGE

Glue and clamp three pieces of3/4" × 2-1/2" × 11" stock to form thefuselage block. If making more thanone plane, allow about 11" lengthfor each fuselage. Cut the block tonished dimensions; then draw thetop and side proles on it.

Cut out the wing notch on thebottom and the rear tail notches.

aper the sides of the fuselagewith a scroll saw or bandsaw. apeback the scrap pieces. Place thefuselage on its side and cut theside prole.

Finally, with a rasp or powersander, round off the edges of thefuselage; then bevel the nose.

Set the fuselage aside.

2. WINGS

Make the upper and lower wings(B, C) at the same time. Begin with

a piece of stock at least 3/4" thickand 13-1/2" long. Te proper widthof the wings is determined by thenotch already cut on the fuse lage.Remove the excess width of thewing stock until it ts the notch.

Lay out the location of the wingstrut holes and drill them with a

5/16"-diameter drill bit. Resawthe stock into two 3/8"-thick wingblanks. Form the round contouron the wing tips as shown; thensand the tips smooth.

Glue and clamp the lower wing(C) to the fuselage. As semble the

upper wing (B) to the fuselagewith the wing struts (L). Sand thewing struts ush with the wings;set the assembly aside.

3. HORIZONTAL AND VERTICAL TAILS

Make a cardboard template as inthe previous step and trans fer thedesign to 3/4" stock. Cut out thecontours with a bandsaw or scrollsaw; sand the edges smooth. Resawthe stock to yield 1/4"-thick parts.

Glue and clamp the hori zontaltail (D) to the fuselage; then glueand clamp the verti cal tail (E) inplace. Set the as sembly aside.

4. ENGINE

Glue and clamp two pieces ofstock to form a 1-1/2"-thick piece.Next, resaw the stock to a 1-1/4"thickness. With a compass andstraightedge, draw the outside

circumfer ence of the block andlocate the piston and cylinderpositions. o do this, draw a

2-3/4"-diameter circle; thendraw lines from the center of

the circle to the circumferenceevery 45°. Tese lines locatethe centers of the cylinders.Next, draw a 1-5/8"-diametercircle and bisect each of the45° angles with another lineto the outside circumference.Mark 1/8" on each side of these

bisection marks and connect themto the 1-5/8"-diameter circle (seedetail in the plans).

Now it’s time to start ma-chining. Use a scroll saw orbandsaw to cut the block round.Sand the edge smooth; then drillthe 7/16"-diameter cylinder holes

1/4" deep. After drilling the holes,form the pis tons with a scroll sawor bandsaw (see Fig. 1).

Finish the engine block bychamfering the edges with apower sander or rasp. Gluethe cylinder heads (G) intoplace; then set the engine

block aside.

Fig. 1. Cut out the wedges inthe en gine block to create thecylinders. Make the cuts witha bandsaw or scroll saw.

5. PROPELLER

Lay out the prole of the pro peller

(H) on a piece of 1/4" plywoodor clear stock. Drill the 5/16"-diameter shaft hole in the centerof the piece; then cut out thepropeller with a scroll saw. Sandthe edges smooth.

Drill a 1/4"-diameter hole intothe end of a length of 1/2" dowel

stock to make the pro peller hub( J). Cut the hub to length; cut andglue the pro peller shaft (K) intothe hub.

With a 1-3/4" diameter holesaw, cut a 1-5/8"-diameter blankfrom 1/8"-thick stock to make thepropeller spacer (I). Glue and clamp

the spacer to the engine block.o assemble the engine and thepropeller parts to the fuselage,glue the engine block to thefuselage assembly. Te spacer hasa 1/4"-diameter hole that can beused as a guide for drilling thepropeller shaft hole through the

engine and into the fuselage. Usea 1/4"-diameter drill bit and makethe hole according to the plans.Glue the propeller shaft andpropeller into place, being carefulnot to get glue on the propeller.

6. WHEEL STRUT ASSEMBLY

Tis plane has a wheel strut blockthat goes under the fu selage. ofabricate the piece, cut stock tothe proper length and width. Setup a drill press to drill holes inthe block at a 30° angle as shown.After drill ing the holes, form the

contours by tapering the sides 30°and the trailing edge 45°. Roundthe bottom front edge with apower sander or a rasp to contour.

Make a V-block to hold roundstock, and drill the 5/16"-diameteraxle holes in the wheel struts (N)at 30° (see Fig. 2). After drilling theholes, glue the struts into the wheelstrut block, using the axle to keepthe struts aligned. When the gluedries, sand any excess strut stickingthrough the block. Glue and clampthe block to the fuselage.

7. WHEELS

With a 1-1/2"-diameter holesaw, make 1/8"-deep kerfson 1/2"-thick stock. Use a2-1/8"-diameter hole saw to

cut out the wheels; sand themsmooth; glue the wheels and theaxle to the struts.

8. FINAL TOUCHES

o nish, put the tail skag (Q) onthe plane; its location and angleare not critical. Drill the 5/16"-diameter holes and glue the skagin place.

If painting is your nishingchoice, paint the entire air craft yellow, engine and tires at black,and the propeller silver. Makeinsignias out of contact paper and vinyl lettering.

Fig. 2. With the ta ble tilted30°, secure the wheel strut ina V-block to drill the axle hole.
