A call to Forum Members to Contribute......FAv Formulas

[NewLou]

Gidday Everyone:)

My Maths is that bad at the best of times!!!

I have trouble working out measurements..... what I thought would be really Handy for all forum members is if we post our favorate formulas websites etc when it comes down to all things about where to cut; place that router bit................ or mark that Line!!!

This a call to all Aussie Forum Members to contribute your favourate woodworking formulas:

........................and please no pancake recipes:D

Lou,
Do a bit of surfing and learn about story sticks.
Draw your parts fullsize.
(CAD can be such a pain - just use a pencil and paper or cardboard etc
You dont need much math to do it very accurately.

As an apprentice I made a monumental balls up in the WorkSkills Australia national finals that probably cost me 1st or 2nd place. Despite being in engineering in one form or another since I rarely fly into building something without a sketch. I figure if I can draw it I can build it....which is why I never got into yacht building:confused: .. Do the sketches and it doesn't really matter if they are not to scale (unless your into the art side of things;) ) and mark all your dimensions. Use the plastic brain to check and you at least wont make monumental stuff ups with expensive materials:o .

There are some great tips hereabouts for cutting plans on sheet material.

"Unconeer" can be downloaded free from http://www.katmarsoftware.com. Its a unit conversion program.

How the hell do you do a pye symbol on a qwerty keyboard??

NewLou, your thread was moved here, because you are calling for website links, hence it is now in the appropriate forum.

Boys, while I appreciate your humor, lets try and keep this thread on track as it will no doubt become a very valuable source of info. SO for that reason only your posts were deleted.

CAD can be such a pain

Echidna,

I have found that if you take the time to master a CAD program - and the 2D features are not that hard - CAD is very useful, particularly if you are into designing your own pieces. I would encourage anyone who aspires to be a serious woodworker to use CAD.

[powderpost]

Not exactly a formula but to make an octagon from a square, mark the diagonals and use half of one diagonal as radius from each corner as centre, mark an arc that should go through the centre point of the square onto each side. Join the end of these arcs together and you should have an octagon.....

I know you're absolutely right Rocker. :2tsup:

But I'm having trouble even getting my head around sketchup at the moment.
I'm momentarily disinterested in frustration. :D

Pity there wasn't an easy to understand guide to using it.

When you are in a 10m room and have to build a raised floor with a 20m radius then the equation of a circle is the only way to do it.

I only have a faxed copy and will try to post it later if any one is interested.
