# Drawing ovals and other things without maths

a better demo of how to draw an oval or as they call it – Construct an ellipse with string and pins.  Would have saved me writing this 🙂

more Geometric Constructions – or “how to draw stuff without a tape measure and protractor” ->

useful demos on those pages on making common angles like 45 degrees, 30 and 60 degrees, how to make a hexagon, how to make a line parallel to the one you’ve got.

I remember my maths teacher at school teaching us these, but I’d forgotten all about them…   right, off to find a compass and ruler to practice them.

# Draw an Oval (an ellipse) – No maths required

Tonight I learnt some Simple, practical geometry. No Maths required. You just need 3 nails, a piece of string, a ruler and a pencil.

# Woodworking tips 1

Just started a woodworking class.

• get some basic tools – rule, set square, tenon saw (more teeth per inch = finer cut), marking gauge, chisel
• a bench hook is great – and you can make one
• measure twice, cut once
• take your time, let the tool do the work
• mark the wood you are going to remove, and cut on the waste side of the line you’ve marked – you can always take more off, but you cant put it back.
• a saw can make a mess of your fingers – treat it like a big sharp chefs knife – keep your fingers away from the blade: tenon sawing
more tenon sawing
• rub a candle (never oil) on the side of the saw if it squeaks and sticks in the wood.
