IE if original plans call for 1/8 thick wings and I go two more inches in size linear how do I compisate or figure for thickness? TAV -- saw dust makes tree huggers happy

If it was 6” and you increased it to 8” you increased it by 33% 1/3 of the 6”. so if the wood was 1/8 for the wings then you would do 1/3 increase of the 1/8 1/8 = 3/24 You would increase that to 4/24 or 1/6”. It would probably to do it easier if you converted it to thousands of an inch and then make the result something that you could cut. 1/6 would be close to 5/32 of an inch. -- I've been blessed with a father who liked to tinker in wood, and a wife who lets me tinker in wood.

Multiply all your dimensions by 1.2 and you have your sizes. I hate fractions so that is how I would do it. In Karsons example above 8/6 = 1.33 so multiply everything by that. Just round everything up or down to a simple number, even fractional if that’s what you are used to. -- Gary - Never pass up the opportunity to make a mistake look like you planned it that way - Tyler, TX
