Goemetric Problem

[espookid]

Sorry about this on a Sunday morning
I am making a 5 pointed star ,normally the internal angles are 72° but I want to lift the star "fingers"up 15° to form a bowl shape and need to know the new angle is it 60 °? Based on the 75/90 *72 ?
Thanks in advance

Do you mean lifting them up out of the page?

[espookid]

Yes to keep the centre on the page and lift the fingers

It may depend on the depth of the bowl you want -- but I think you will need the angle to be bigger, not smaller. Otherwise you would form either a pentagon-based pyramid, or a bowl with gaps in.

Thanks for the response Jim360 but I tried with 72° and a compound bevel of 15° and when I came to the last piece -as I am making a candle holder- it was too big so it will be less than 72° but because of resetting the saw every attempt I thought I would ask on here

If you had a paper star and folded the 'fingers' up wouldn't it give the effect you want. There would be no change of angle. Or have I misunderstood what you are trying to do?

[espookid]

Yes I am sorry you have misunderstood as i am making it from wood but thanks for your time

Espookid, why not make a paper one and use it as a template, if you make it sufficiently oversize to compensate for the bevel of the joints it should be relatively simple.

Just give it a go and see how it turns out. If it looks ok, measure the angles and let us know what they are.
