Trivets

[Phil]

Trivets – an exercise in accurate measuring and lots of patience ……………..

An oldish project as the fotos were still in F-ktBucket

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!!!!)



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 )


Some highly accurate construction drawings …………..



and then at the back the accurately thickness & trimmed 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 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.

A bit of sanding cleaning up the grooves



Here is a complete top and bottom.



Then off to the oiling station for a couple of layers of Danish oil.

{This foto went missing …………}

One set complete.



I kept one set which I use when we BBQ and gave eldest heir the other set which is in daily use.
I have subsequently given him the second set as well.

Cheers

Nicely done Phil

I got a trailer load for me and another for a mate years ago when they were ripping the labs out of a local high school and still have quite a lot. Mine came with bunsen burners still attached and the obligatory kids names and obscenities scratched into the surface. All 30mm thick though so useful stuff but it does splinter easily.

Thanks guys.

Bob, that adds character depending on what it will be used for.
The mahogany is very nice to work with.

I think mine is probably sapele Phil. I still have sections of worktop around 3m x 900mm and other offcuts.
I also cadged a load of what I was told at the time is Brazilian mahogany in various sizes up to 100mm thick, offcuts from the Riley snooker table manufacturers in Lancashire, filled my estate car for £5 but that was nearly 50 years ago and they had a room size pile of large offcuts. I've used and given away a lot over the years but still have enough to see me out and then some.
