Client wants a round base

Hi All.

The topic of this thread has been our (apprentice and I) lunchtime talking point for a few days.
Both of us are overwhelmed by how much maths comes into play in our profession and i feel it's one of my weaker points.
I have difficulty reviewing a complex math formula and can't seem to follow the subject or see the relation in the flow. When I read Tom's simple 360 divided by number of pieces divided by two equals degrees to cut pieces I rejoice.
Even simple roof angles, runs, degrees and pitches have me head scratching but my experience gets me to a tight fitting rafters but not straight from paper but rather from a drawn template or trial pieces.
I'm hoping that YOUTUBE content on related subject brings me the kind of Eureka moments I need.
Thanks for the education, it's why I love the FOG.

That bit in bold, that's a typo right?

[member=25539]SMJoinery[/member] remember that only works for equal side length polygons.

[member=20162]Wuffles[/member] I think everyone looks at math as all inclusive, be it geometry, trig, algebra, calculus.....

Thanks everyone- what a pita this turned out to be

You would think it would be harder to take a round tree and make it square...  [blink]

Good luck with your project, Frank.

I was just trying to assess whether [member=25539]SMJoinery[/member] had become Americanised. We say Maths over here, not math  [smile]

 

[SMJoinery]

Howdi...
Me Americanised?, no way partner!
I'm just simply saying thank you kindly for explaining to simple folk like me a difficult math problem.
You all take care now... [tongue]

(Deepest apologies to my American friends and family) [eek]

Thanks Shane - Tom and everyone that has helped

Hi All.

I have difficulty ...

When I was doing high school math(a) I was pretty oppositional to algebra and trig.
The teacher had no examples of where or why it was used.
Later I was working as an apprentice (CNC) machinist. When I helped out Rocky with some trig I moved straight to programming.
(Time lapse)
Now I am somewhat of the local SME on solid geometry.

It would be a lot easier to learn maths in something you know.
At least for me pure maths has nothing I can grasp.
There is a write up by a fellow that makes French saw horses treteau - I bought his book, which may be ideal for you.

Here is his site: http://thecarpentryway.blogspot.com.au/2009/11/treteau.html

Look up some segmented turning sites. There are programs that let you plug in #of sides,interior diameter, outside diameter and boom there are your measurements.

Curious, as to whether project went anywhere...

 

[Shane Holland]

Yes, [member=7322]Zacharytanner[/member], we need photos!  [big grin]

It's worse than that, today I noticed that some don't even understand that sheet goods* is the singular there's no such thing as "sheet good"! (Even in amerikans as opposed to the Queen's English!!!)

*the culprit is cutlist bridge - sketchup -> cutlist fx software

Anyway back on topic(ish) [member=25539]SMJoinery[/member] there's some great resources on the web now for solid geometry stuff

Fascinating comparing say http://sbebuilders.blogspot.co.uk/ with http://www.basiccarpentrytechniques.com/A%20Manual%20Of%20Carpentry%20And%20Joinery/3%20A%20Manual%20Of%20Carpentry%20&%20Joinery%20Solid%20Geo..htm
