I have just made this simple segmented bowl.
I think it looks quite good i will show you how it is done.
I am teaching tomorrow and Saturday but i will try and fit it in.
To make this bowl i used approx 6' off 12" x 1" yellow pine board available from most builders merchants
that supply timber.
It is made up from 12 pieces end grain and 3 pieces long grain 3 1/2" thick .
This piece could be made with nothing more than a bandsaw and some clamps if that is all you had.
I started off by cutting 12 pieces from the end of the board with my sliding chop saw.
only been through a planner at the mill I like to sand it so that I get a nice surface for gluing.
I have done this on a belt sander simply because i have one but there is no reason why this could not be done by hand.
I clamp up as tight as i possibly can and have made a lot of segmented bowls and never had one fly apart."Touch wood"
My brother Chris makes segmented bowls without clamps by using his large woodworkers vise.
Not many of us have a vise that opens that wide but i suppose if you were going to make a lot of segmented work it might be worth considering.
You cannot skimp on the glue when you do segmented work or you could end up with dry areas and the problems of your work coming apart on the lathe.
After gluing up this block needs cutting into three equal parts ready for the three slices of long grain to be glued in.
I found that it was about a 1/4" too thick for the chop saw.
Just to see how good a cut I would get I took a thin slice off one side with my bandsaw and a 1" blade.
I was not really happy with the finish.
It would have been Ok if I was prepared to do a lot of sanding.
I have a bench saw that is capable of cutting this thickness but I have to move it out and put the sliding table on and i could not be bothered.
saw I put plat C into practise.
A quick phone call to my mate Richard Fairbrother http://www.richardfairbrother.com/.
Richard has the best equipped workshop I have ever seen and makes the most beautiful Bespoke furniture.
Anyway he said he would be happy to do the cutting up for me.
Then he cut it into the three equal sections.
Thank you Richard.
I wanted to get on and get this finished now as I had other things to do so i thought i would give Gorilla glue a go to speed things up.
I have never used gorilla glue before ,it said on the can 1/2"hour clamping time so i clamped it up for an hour to be on the safe side.
I am well impressed it was easy to use and after an hour it was cured and ready to use.
When you do this it is very important that you mark out your circle from the dead centre or when you have turned your bowl the two ends will look different.
Now we have a solid blank 12" diameter 3 1/2" thick ready to turn.
and I will do my best to answer.
