A variety of [https://en.wikipedia.org/wiki/Chassis '''Chassis'''] designs with wheels, axles and bearings can be created with '''[[Stripwood Technology Materials]]'''.

The examples below are based on vehicles but the same general constructions can be used when moving parts are needed on many other working models ''(e.g. fairgounds, seige weapons, cranes, moving bridges, watermills and windmills)''.

When combined with '''[[Box Modelling]]''' techniques quite large and complex working models can be built using a minimum of tools and easily obtained everyday materials which, where neccessary, are glued together using '''[[Glues and Pastes|PVA Glue]]'''.

{|
|-
| '''Box Model Chassis'''
| Wheels can be added to box models to create working models. Holes for axles can be created by pushing through a sharpened pencil. The roughly pierced hole can be improved by gluing over it a piece of card into which a neat hole to receive a '''[[Stripwood Technology Materials|Dowel]]''' axle has been made with a '''[[Punches|Paper Punch]]'''.
----
'''Safety Point!'''
It would be quite dangerous for young children to try and pierce the holes using '''[[Scissors]]'''

----
Wheels made from discs of MDF are spaced out from the box sides with '''[[Nuts, Bolts and Washers|Washers]]''', or short pieces cut from PVC tubing, and pressed on to the ends of the axles - the spacers are needed to stop wheels rubbing against the box sides.

|-
| '''Felt Tip Pen Bearings'''
| The outer plastics casing of discarded '''[[Pens, Pencils and Scribers|Felt Tip Pens]]''' can be trimmed using a '''[[Hacksaw|Junior Hacksaw]]''' and fixed to a piece of '''[[Paper and Card|Thick Card]]''' using elastic bands as shown.
----
'''Note:'''
Elastic bands are used because the plastics casing cannot by glued satisfactorily using '''[[Glues and Pastes|PVA]]''' - but '''[[Stripwood Technology Materials|Cable Ties]]''' and foam adhesive pads are alternatives.

----
An advantage of using felt-tip pen casings is that they can be cut a little longer than the width of the chassis and this stops the wheels rubbing against the side.
| [[File:FeltTipAxles.png|300px|right]]
|-
| '''Clothes Peg Axle Holders'''
| Wooden spring-type clothes pegs can be glued on to boxes, card or '''Stripwood''' frames to serve as axle holders.
----
'''Note:'''
Wooden pegs are used because those made of plastics cannot by glued satisfactorily using '''[[Glues and Pastes|PVA]]'''.

----
Clothes Pegs also add realism to models by giving something of the appearance of the suspension and related mechanisms present in actual vehicles.
----
'''Activity:'''
Using pegs enables the axles and wheels to be made easily interchangeable. Explore the effect of different wheel diameters and widths by changing them and rolling the same vehicle down a fixed slope to see how far it goes each time.

----

|-
| '''Wide Wheels'''
| MDF discs can be fitted together to make wider wheels. This can be done for added realism in a model but it also adds to [https://en.wikipedia.org/wiki/Rolling_resistance '''Rolling Friction'''].

For free-wheeling vehicles this, may be a bad thing but for vehicles driven through the wheels, quite advantageous because it provides greater [https://en.wikipedia.org/wiki/Traction_%28engineering%29 '''Traction'''].

Lengths of '''Stripwood''' can be added to a card chassis to stiffen it.
| [[File:DoubleWidthRearWheels.png|300px|right]]
|-
| '''Large and Small Wheels'''
| Some vehicles ''(e.g. Tractors and Steam Railway Engines)'' may need wheels of different diameters front and back.

This can be achieved by mounting axles over and under the main chassis. If a greater difference is needed, extra lengths of '''Stripwood''' can be glued under the peg axle holder.
| [[File:Tractor.png|300px|right]]
|-
| '''Card Axle Holders'''
| Axle holders can also be made by punching holes in the '''Card Triangles''' used for general construction reinforcement.

Thicker card can also be used to make stronger axles and '''Eyelets''' can be inserted to make improved bearings.

|-
| '''Flanged Wheels'''
| Card discs can be added to the side of MDF discs to create '''Flanged Wheels'''. These are useful for vehicles which are guided on rails ''(e.g. Railway Engines, Dockside and Overhead Cranes)''.
| [[File:RailwayEngine.png|300px|right]]
|-
| '''Drinks Can Wheels'''
| Empty soft drinks cans make unusual wheels - or model rollers. A card or MDF disc placed over the end of a can is used to mark the centre and an axle hole created by punching through with a '''[[Punches|Nail Punch]]'''.

If required the card or MDF discs can be retained on the end of each can but would need to be fixed with '''[[Adhesive Tapes|Double-Sided Tape]]''' for example - since '''[[Glues and Pastes|PVA]]''' will not glue to metal satisfactorily.
