« Part 13: 1500mm Table Top clamping the sections up Part 14 of Furniture series Part 15: 1500 mm Table attaching the edges »

I released the clamps this morning and with the help of my wife got the table top up onto some temporary stands, they are simply four metal table frames 600mm x 600mm each so I just taped the four center legs together to make a work platform

Using my building square and tape measure I checked the table for overall dimensions and squarness.
Sure enough the diagonal measurements showed it was out of square by about 10mm.
So after doing some more precise measurements I set up my saw guide and used my 7 1/4 circular saw to trim the table top and square it.

A note here I had to invert the table face down to remove any chance of splintering by the circular saw as it rotates the same as a table saw but up upside down.

I didnt take any pictures of this process, maybe beacuse I was a bit nervous doing it.
However as a result I was able to achieve squareness to about 1mm so I was happy to leave it alone at that amount of error.

A note added: If you are wondering what I have on the corner I was experinenting with some timber to see how the edging would look.

I then set up my 1/2” Router and rabbet bit to cut the “tongue” profile edge I did a test cut on some of the offcuts and determined 8mm was a good division of the timber,
I “flipped” it over and did the oppisite edge, mind you it was no easy feat as it was so big and risked breaking it in half if I tried to turn it by its side rather than its edge however with the help of my “assistant” again we did it.

As I was rabbeting the other edge all went went until I felt the router kick a bit.
Upon stopping and checking I found the tongue of which the bearing was using as a guide had splintered out and ruined the edge.

This completely deflated me and I wondered what I could do

Upon checking close by I saw a lesser splinter effect as well (no doubt the grain was reversed on this piece)

I stopped work and went and made a coffee pondering as to just how I was going to fix it.
It really got to me and I lost a lot of my motivation when it happened, however after walking away for a while I considered the only possible fix was to carefully reroute the tongue to remove the defect divot and then re rabbet the edge again.

I spent quite a lot of time measuring/checking and setting up before I was confident my fix would work

Sure enough I managed to fix it but decided to put it all away for the day and continue later.

I am used to moving sheet material around on my own and had the little “skateboard” under it to get it back inside and then put it into the wedge clamps.

well tomorrows is another day I guess, boo hiss!!

Coming along nicely Rob, there would be no fun in it, if Murphy didn’t drop by to ‘help’ occasionally!!!!

I hate those de-motivating episodes! Good for you figuring it out and marching onward. I, too, really like the skate board.

Thanks everybody, I was really disapointed when the chip out happened, I even contemplated leaving it there and just filling it with a piece of off cut later, but it was only after I walked away and had a re think about it all I was game enough to take on a resaw/rework activity.

How I fixed it:
I measured the depth of the gouge and then using my saw slide edge and a small trimmer router and a new bit I removed all the tongue in a couple of passes by tapping the saw slide in after each cut until the gouge disappeared.
I then diamond dressed the original rabbet bit to ensure it was as sharp as possible.
Set up the 1/2” router again and used the reduced tongue as a guide to re route both sides again going very slowly along the board. A good result this time!

What caused it?
Possibly any number of factors,
1 The bit may have not been sharp enough.
2. I milled the timber against the grain.
3. I inadvertently tilted the router base down on the outer edge causing it to gouge the tounge and splinter it out.
4. Feeding the router too fast for the job.
Who knows but with a bit of pre preparation and a little more care it did not happen again…Thank goodness!!

The timber Skate:
Yeah its a sought after item when small kids visit they love standing on it and getting somebody to roll them along. The wheels actually have needle roller bearings and its very easy to move anything on it.
In fact you have to chock the wheels other wise it shoots out from under the work you are trying to load on it at the time!! My mate even borrowed it to move his spa, he built up the timber above the wheels put it under and away he went!

Anyway today I am off shopping for edging timber to continue on as I do not have any stock 1600mm or thereabouts to work with.

Thanks again!!
