Topic tags/keywords: tip question trick

I’ve been trying to figure out how to make an arched gothic window frame. For the box part, I’ve been bending 1/2×2”, or 1/2×4”, and meet them at a point at the top, then laminate each one about 3 more times maybe. Is there a better way to do this? I’ve been searching youtube, and google and haven’t seen anything whatsoever. I’ve seen some of them in sections starting at the bottom of the bent part (about 2/3 of the way up the sides), but don’t really like that look. I’ve also tried making it within a normal rectangle frame, but that takes away from the design contrast of siding vs an arched window.

In case you don’t remember or don’t know their shape, here’s an image link to one..

I think you are on the right track. There are various ways to create curved pieces of wood, including:

1. Cut from the solid
2. Kerf bending
3. Steam bending
4. Bent lamination

You are using a “cold bent lamination” technique, which is what I would also chose for a project like this. I typically build a bending form first, and glue-up the lams on this form. Thinner lams bend easier, with less spring-back (1/2” is pretty thick, but your bend is relatively slight, so 1/2” is probably fine).

I’m sure you can find more info on the subject if you search “bent lamination”

Yeah, the bending form is tricky on this since gothic arches are an irregular curve. 1st attempt- butchered with a jig saw. 2nd attempt, still apprehensive using the 18” bandsaw, wandered off the line a little. So bent lamination I guess is my most practical solution; instead of trying to cut a perfect curve, I’m thinking of just doing some nails or screws into a surface, and start laminating from there by bending the pieces within the nail pattern.

My understanding of a gothic arch is quite regular—-made with circular arcs. See this link:

Bandsaw would be my tool of choice for the form—-you can always patch with Bondo and sand to shape
