I am about to start on the first of four sets of garage doors and frames. I am unsure how to make the arched frame above the doors and am torn between curf cutting a wide board or laminating the arch from smaller pieces. Dimensions are 2" thick and 8 1/2" wide. the frame will sit inside arched brickwork and the design is this for the frame and doors.  All timber will be Treated softwood. TIA.  |

Hi Mailee, not something I've tackled but have seen a couple taken apart.
The first was kerf cut pieces and quite old.
The second was laminated with a moulding planted on the front , the laminate was fine but the moulding hadn't survived to well.

Traditionally the curved frame head would be from cut from 2 solid pieces with simple bridle joint with draw bored peg at the meeting with the jambs, and the middle joint being one or two loose tenons dropped in from above - or if you want to be clever the wedged keyed hammer head loose tenons as shown in Scrit's christmas quiz earlier.
The door head also would each be one solid piece with a fairly normal M&T at each joint + draw bored pegs.
This would be by far the simplest and best way of doing it and I wouldn't bother with any clever kerfing or laminating.
Trad way slightly wasteful in materials but would save a lot of time, and you'd use the curved offcuts for something else interesting!
cheers

I made an arched door and frame a while ago and the main problem for me at the time was the 4" thickness of the arched frame so 8 1/2" will pose even harder i think . I wanted the frame to be one solid piece and was using a router and hand tools  ;D The wedged key hammer head thingy joint that Jacob mentioned sounds the best way to me . |

Just noticed it's 8x2. More of a door lining than a frame. Odd dimensions IMHO. A bit thin unless you are planting on stops rather than rebating, and unnecessarily wide.
Trad frame'd be more like 4x5 with rebate included.

The only reason i can think of for frames of this section is the crafty builder wants to build them in to act as formers for the arch .If so talk him into a purpose made former ,suported on a pair of folding wedges each side this makes it easy to strike.Then you can make the casings a more managable section cheers john
