The ratio I have been finding is 1 to 1.61, something about the Golden Numbers? Went through about 13 pages of cross projects/forum topics on the LJs search !

I don’t know if there is a right and wrong ratio but I’m curious which of these do you like best? It’s not a trick.

Either of the 2 on the left. For me, it would depend on actual size of the crucifix.

Sort of what I am thinking, as well as the color and style of Crucifix may impact the design?
Playing with the idea of a interlocking block construction for a more modern design.

Have you considered building prototypes? If you do, the school might be willing to loan you a student to help test the different versions.

I’d ask to see and measure the crucifix before I try to design a cross. How it looks and what size will depend on that. You can experiment with cardboard to see how several different designs look.
Also I would assume any type of wood would work but it seems like most I’ve seen in churches are made from pine with lights behind them (I’m not catholic tho so I’m not real sure on how they do theirs).

2 on the left are based on 1/3. Also my preference. 2 on the right are based fibbonaci sequence.

I have made up a small model and looks okay, School is out for summer and the building is getting a major reno, thus the new Chapel. Funny thing is they are actually building a Industrial Arts shop but unable to find instructor?
Perhaps if I wasn’t so anti social? Oh ya, sort need a Teacher’s degree and maybe if I was Catholic?

I have shown them some rough sketchs which were approved but then Crucifix was added to job scope, all the other wood in Chapel is Oak so Oak it will be, unless they request otherwise?
My plan is to use a template and sort build it like a reverse puzzle cutting each block according to grain and color?

This sort of what I am working with as per the church doctrine?
Golden Ratio
We find the golden ratio when we divide a line into two parts so that:
the whole length divided by the long part
is also equal to
the long part divided by the short part

Andre, I made one for a local church a couple years ago. I don’t seem to be able to find my plans but the site listed above is what I used. Only I used the 1:2 ratio. http://thecrossweb.com/How%20to%20build%20a%20wood%20cross.htm

My ratio on these was: cross beam was half the length of the support beam and located 2/3rds of the way to the top.

These were 16’ tall, 8’ wide. Cross beam was at 10’ 4” to the center.

Wow! The tools I’d have to buy? Maybe more talent and many years of experience?

Monte, those ratios are pretty much what I have been playing with and looks good, now checking
how much of a taper?
