How to replace cast iron bench slats?

[Sticker]

I have an old cast iron garden bench and I want to replace the timber slats that form the seat.

What should I use for this, are there pre cut slats available ?

Hi @Sticker,

I'd suggest that the closest timber to the dimensions of the slats would be 42 x 18mm 2.7m FJ Pre Oiled Merbau Screening. Do you think that would work?

Hi @MitchellMc and @Sticker 

42 x 18mm 2.7m FJ Pre Oiled Merbau Screening.

I believe that would work. If it is the same generic cast iron sides as mine - I went with 45mm X 25mm with just enough wriggle room to feed the slat through. But - I think from memory I put them through a table saw to get 45mm. I went with 25mm as being exposed to the elements anything smaller cracked when large human beings sat down. 😔

My apologies @Sticker 

Looking closer - the construction is different to mine.

Specsavers. 😞

I wonder how you got on with this @Sticker?

Mine has completely rotted. I tried using some old (and free) decking lengths, but they were hopelessly twisted and bowed.

I'm now wondering if it's even worth repairing?

Simpler to just buy a new outdoor chair?

Hi @Sticker ,

I replaced both my garden seats using Merbau decking. I bought the length closest to what I needed and cut them to the same as what I was replacing using new bolts. Varnished with appropriate lacquer. Don't forget the back strap as this supports the middle part of the seat, stops it from sagging.

Well I've decided I'm gonna just go with pine.

And brace the seat area with Gal steel plate and weld support rods from it.

My theory is the more support there is, the less likely Sticker's situation above can occur.

Just gotta beat the heat outside.

Worked out okay.

The extra steel works very well.

Hi @Noyade ,

Great job! The seat would add to a nice spot in the garden for relaxing or entertaining.

Hi @Noyade,

That certainly looks like it is going to be much sturdier. 

Nice work, as usual.
