44mm double tongue and groove summer house board damage from rotten. How to make new board from plain timber

[Jonny Vee]

I have purchased a summer house which has few boards that have rotten on the side for 200/300mm.

They are 44mm interlock board with double tongue and groove.

Does anyone managed to make those board from plain timber as couldn't source those locally.

Thanks

It's actually 40mm

Assuming that you don't have a spindle molder, can you not identify the manufacturer, and then ask them for replacement parts?

With the right guide fence arrangement you could probably cut the groove in standard timber with a circular saw.

I might have the wrong end of the stick, but I think the op is asking for advice with regards to making replacement sections. On reflection, yeah you could probably use a hand held router to make the 4 beveled edges (top and bottom), and the tongue and corresponding grove, but I don't see how that can be done safely with a regular circular saw.

I suspect that you are referring to the interlocking notch, which yes could be done with a circular saw and chisel.

As I said, I might have the wrong end of the stick.

I've done tongue and grooves like that with a hand-held circular saw. Yes, it does require care to be safe. The result has usually needed a bit of finessing with plane and chisel.

I don't have a spindle molder and can't identify the manufacture. I asked around here for replacement parts but shed shop want only sell full new complete shed which sound bullsh@t

I do have a regular hand held router. What would be the correct bit to buy to make those groove?

my thoughts are
because its dismantled and i assume all the damage is at floor or roof level, dependent on exact number and position you could go for a simple length groove interaction between simpler replacement sections with just the visible surfaces needing exact replication
in other words new timbers would look the same but a single txg groove or a back rebate under the plank to cover the top off the lower plank with a matching rebate at the front edge to hook over
