Cut curves in thin material.
Describe characteristics of band saw:
1) Heavy duty, large
2) Cuts IRREGULAR SHAPES in timber.

What is planing used for?

How to use “between centres turning” to form round components like chair legs
1)Begin with SQAURE section of timber with edges PLANED off. There should be SAW CUT across the end
2) FORK CENTRE (connected to motor) holds the wood piece on the on the HOLLOW SPINDLE in the HEADSTOCK and DEAD CENTRE in TAILSTOCK allows the wood to spin freely.
3) Whilst rotating the wood, tools placed on REST to cut and carve shaped into wood.
How to carry out FACEPLATE TURNING? to create bowls
1) Wood piece, flatter an larger than in between centre, screwed to faceplate that is attached to hollow spindle.
2) Motor spins the wood and tools placed on rest to cut and carve the wood piece.
What does a router do?
