I could use some advice to confirm that my approach will stand he test of time. Not 100% certain on which forum this belongs in…
This is for an outdoor harvest patio table. The top will be 6 pcs of quarter sawn white oak with final dimensions of around 130×50x2. The wood itself should last decades, and I’d like the table top to do the same. The current plan is to join the table top boards with gorilla glue (it should hold up to the freeze/thaw, wet/dry and hot/cold of eastern Ontario). The manufacturer and various web postings suggest this is a good product but nevertheless, I’ve been testing a sample piece by repetitively soaking, freezing and drying… So far so good but this has only been a few cycles.
To help keep things well aligned, I also plan to use a mix of wood and metal biscuits. I considered a simple tongue and groove joint at first but I don’t see a lot of value in it versus the ease of the biscuits.
Below the table top will be 4 cross pieces (roughly 4×45x2). These will be screwed in place with sliding washers to allow for any expansion across the width of the table (I’ve read that 5% is a high upper end of the expansion possible across quarter sawn wood like this). The table will have an hourglass-type leg near either end.
Please advise if you think the approach described above is unlikely to last a couple of decades or if you’d advise a different approach…
I’m awaiting the materials (by mid-may) and will post photos once the project is done.
