Old Oak
Oldish project
Trivets – an exercise in accurate measuring and lots of patience ……………..
The stock used is recycled Mahogany. It came from a laboratory counter top when an old paper mill was shut down.
The chap then used it at home as shelving for his wife’s sewing room. Then they renovated, threw out the shelves which I then gladly relieved them of.
I had to use some seriously powerful foul smelling paint stripper to get all the old varnish off before I could run it through the TP (sh---t that stuff burns when it get on your skin!!!!)
Some highly accurate construction drawings and then at the back the spacer strips that would used when routing the grooves. Some old scrap PB.
The first cut is with the timber against the fence, then 2 strips against the fence and so on.
The planed stock ready for cutting to size.
There will be 4 trivets, 2 short and 2 slightly longer.
(I did consider doing 2 long ones and then 2 shorter ones)
Cut section ready for the router.
The base routed on one of the pieces.
Routed using a round bit, adjusting the height by 0.5mm until the depth is at the middle of the timber.
There are 8 grooves per piece, and 4 pieces = 32 grooves which are 9mm deep.
Then adjusting by 0.5mm increments, that equals 18 height adjustments, by 32 grooves = 576 cuts just for the base.
Then of course the whole process is repeated for the tops.
8 Grooves times 4 pieces times 18 height adjustments = another 576 cuts for the tops!
If you cut accurately, then on the final cut you will end up with a hole between the bottom groove and the top groove.
The final routing is the round over bit on the long sides.
Here is a complete top and bottom.
Then off to the oiling station for a couple of coats of Danish oil.
One set complete.
I kept one set which I use when we BBQ and gave eldest heir the other set.
Cheers
Phil
