Topic tags/keywords: question

After building two baptismal fonts last fall, I thought I was out of that line, but I have another one to build. I don’t do this for profit—I might get enough out of this one to get a proper HVLP system.

My design parameters. I like open designs using a glass bowl so the water is visible. I like the symbolism to be in the design itself, not decorative designs attached (like a cross that is attached to it).

Here is the font I made last fall, a design I like a lot:

I’ve been asked to build a font for a colonial space: darker wood at the top and bottom with white painted middles. This sort of look:

The most interesting shape in the chapel is the window:

I’ve come up with a concept, but I think it has two major weaknesses: 1) I don’t think it would be stable over time. Looks like a design that could easily get wobbly; and 2) (related) that I’m not sure of joinery.

I will probably add a shelf to it like the one I did above, and that would help with the stability, but I think it may just be an inherently weak design.

I’m thinking there may be a more subtle way to include the window shape—more of an allusion than the actual fulll shape.

I’d love any design feedback you might have.

here are two views of the concept:

Insert a cross into each arch, that would strengthen things considerably…

Good Luck!

What about that open design that you showed and in each open segment, mimic the shape of the cross in the window for looks and support, painted white or whatever.

CharlesA,

I like the overall appearance of the baptismal font design you are now considering; and the baptismal font you pictured looks very good. I hope my comments help you advance the design.

If some cross bracing were added within each arch, tendency for racking of the arched frames would be reduced. Taking a que from the stained glass window, the cross bracing could consist of a cross, where the post would run from the bottom rail to the center of the arched top. The cross member of the cross, let into the posts with a half lap, would connect the vertical stiles of the arch. Connecting the four points of the cross could also be done with half lap joints. The same trammel setting used to shape the short radius of the arch could also be used to form the half lap at the top of the cross where it meets the top of the arch. A flush trim bit, sanding and/or hand work could fair the top end of the cross’s post along the long radius (upper) of the arch. Alternatively, the posts of the cross could extend up past the top edge of the arch and provide support for the bowel’s retainer platform.

But since there are three arches, I assume to represent the Father, Son, and Holy Spirit, arch cross bracing that represent each member of the God Head could also be used. I can come up with two of the three symbols; a cross for the Son and dove for the Holy Spirit. Unfortunately I come up short on a symbol that would evoke the Father. These could also be joined to the arched frame with half laps.

The bottom rails of the arches are even with the bottom ends of the arches. Any unevenness in the pedestal or the floor could cause the font to rock. Moving the bottom rails up some distance would create 6 legs, which would, I think, add to its stability. If the bottom rails are raised 3” to 4” up from the ends of the stiles that make up the arch, a toe recess would be created, allowing the man of God a little closer access to the bowel.

My guess is that the font will be portable and put away when not needed. Unless the font is permanently anchored to a base, there is no structure tying the arches together near the floor. I suppose this is one reason why you are considering a shelf of some design. Symbolically I like the idea of some structure that ties the three arches together to symbolize the Trinity as One.

One approach to the shelf is a triangle that connects the bottom rails of each arch or into the post of the cross (if this design element is added). Adding a gentle curve (concave or convex) to the triangle would soften the appearance of the shelf. The shelf could be attached to the rails with dowels or mortise and tenons (loose tenons might be easier). If further symbolism is desired, three shelves could be installed rather than one.

I am not sure how easily the font could tip over on its side. This would depend on the mass of the font at its base versus at the top, the height of the font, and the width at the base.

Lastly, though I am not sure whether you are pondering the construction of the arches, cutting the arch from a single piece of stock would increase the likelihood that the arch would split or crack over time. A bent lamination or steam bending I suppose are alternative options, but I would think the easiest way to construct strong arches would be to glue up segments from which the arches are cut. Since reinforcing the mitred end joints with dowels or splines would be tricky, considering a segmented face lamination of three segments where the mitred joints are supported by the adjoining segment could probably work.

I am a little confused. It doesn’t sound like you are going to make an enclosed base like the one you pictured as an example of what they want? Could you simply make the hexagonal cabinet and add the arched frame as molding? You could even apply a cross that mimics the stained glass.

I really like the curves of the font you made at the top. If you are going to create an open design as your sketch shows, perhaps you could embellish the design of the one you built by making the curved uprights into crosses whose horizontal beams merge to match the match the sides of the hexagonal base? (Does that make sense?) They could form the core support for the bowl. If you want to incorporate the 3 arched frames, then they are simply cosmetic and you won’t have to worry about them failing structurally.

Thanks, everyone, for your thoughts. Three crosses won’t work symbolically win this as the foreign focus is Trinitarian. You’ve convinced me that this initial design is fatally flawed. I have another idea I’m playing with—I’ll post it soon.

Maybe solid panel the aches/windows and do the cross shape as a cut out???

BTW very nice work on the shown photo

Have your say...
