I'm confused by online urn size calculators so I need your help determining a rough estimate on size of blank for an urn. They want a wood that is not a local wood so I will need to buy and have a piece shipped. Trying to determine a ballpark size of the blank to know what total cost is with the cost of the wood and shipping weight.
Here is the info I have: Most sites say a cubic inch per pound. The person weighed closed to 140lbs which according to the urn calculators is around 140 cubic inches or 9.5 cups of volume. The family estimate only 60-70% of that is left as the family spread some ashes. So if I estimate 100lbs that's about 7 cups and 100 cu inches. If I do a volume calculate of a cylinder I would need roughly about a 3" radius and a 3.5" height of INTERNAL capacity for 100cu inches not including exterior shape or wall thickness and a lid of some sort. So I may be wrong (and those experienced in urn turning - please correct me if I am) but a piece at a minimum should be somewhere around 4.5X4.5X8 might be big enough. But something a little larger would give me more shape/design options.
Just speculating here - but a medium flat rate box is 11 1/4" x 8 3/4" x 6" so a chunk of wood 8X8X6 would fit and a large Flat rate is 12-1/4" x 12-1/4" x 6" so an even larger piece would fit. So a 6" diam log or 6X6 square spindle 11" long would fit in either box and that would give me a taller narrow form shape. Or, a square 12X12X6 in the large box would give me a wider shorter form that I could then make a lid out of blackwood or ebony or something.
Any thoughts, suggestions, etc.?
Thanks
