Making large wooden garage door

[Wilson joinery]

Hi everyone

I’m after some advice please on making a large wooden garage door that will be hung on large hook and band hinges. I’ve attached a drawing to try and demonstrate what I’m trying to achieve and how I was going to make it.

The measurements are approximate and there will be 2 of these to be made.

A couple of queries though:

I was planning to have 4 14x170mm dominoes at the end of each rail, so 24 dominoes in total for each door. Will this be ok and would I need to consider pegging them as well?

For the tongue and groove boards do I need to account for movement when I attach to the rebate in the rails? (Leave a slight gap when glueing them up?).

For the braces what’s the best way to fix these to the rails and/or stiles? For the last ledge and brace door I made I just countersink a hole and screwed into the stiles and fitted a plug to hide the screw. Does this sound like an ok method? Would it be better to fix these braces to both the stiles and the rails in this way?

I should also say that this will be made from oak.

Many thanks
Pete

It seems a lot of messing with all those dominoes tbh. Id also put the t and g edge into a groove. Nailing ins ok but they will fall out down the line. The groove allows some room for movement as well as this is what cause these big doors to fail. A wedgded through tenon provides proof against sag as well as your braces and resists that push of t and g expansion (a bit). I like to beef up all my members a bit as well. All a bit ott if your not charging much tbh. I usually advise to get a roller door.
Check out ebay and advise how they make them so cheaply. Id love to know. The very reason these doors last is because they were well made.

Thanks johnny

I’d thought about using proper through tenons but don’t have a mortiser and don’t have a drill press either for removing the majority of the waste although I’d look to get a drill press as been after one for a while. I’ve tried cutting mortises by hand in the past and I’m too slow and not great hence why I’d thought about using my donino machine.

How do you make the wedges for the tenons by the way? Is there a specific size they should be in relation to the slots that are cut in the tenon?

Cheers
Pete
