A simple piece of 40mmx40mm section, about 250mm long, turned to a knob shape at either end, then sawn diagonally and the saw cut cleaned up on a belt sander.....Makes 2 doorstops which sell in my own woodturning shop at £7.50 each.
The maths behind the price...raw materials cost...... 50p
Labour ...12 minutes @£25/hour........................£5.00
Net cost..........................................................£5.50
35% shop overheads........................................£2.00
Retail price......................................................£7.50
I make a batch of several pairs at a time...they don't sell quickly, but one goes every few days, so I guess that the price is about right for the market.
