I have written previously about making trivets, back in September last year. In the earlier post I described making the trivets. This then is the first in a series of posts that describe and show how I made the trivets. I finally decided in December 2012 to get on with it and finish some trivets before Christmas. Essentially they are a 150 mm wooden disk about 15 mm thick. One side has a series of concentric circles turned on the face to half the depth of the disk. the obverse has a group of three concentric circle turned to a similar depth.

I was advised recently to use some Jacaranda for a project. I have been lucky enough to find some at a house that is being renovated. Sadly or otherwise the owners were not there so I left a message saying that I was an amateur wood turner and the logs were going to a good home. Recently I attended the working with wood show in Melbourne. One of the demonstrators recommended Jacaranda as a wood that turn well even if freshly cut. Fear not the ends have been waxed and dated and are now resting in my growing stockpile.
Turned a gavel the other for no other reason that I thought it might be a good idea. I saw a mallet in a recent woodworking magazine so this became my inspiration. I had started the session by turning a handle for an old hammer. This was done off centre and got me thinking about the gavel.
No plans just in at the deep end. I cut the blank from some scrap of red gum that I had bought from the local garden centre. Its amazing what can be made from firewood! I roughly cut the head of the gavel to size and drilled a 20 mm hole with a forstner bit. discovered later that I should have squared up the blank as the hole wasn’t perpendicular.
I wasn’t too fussed with the finishing of the head and the beads are not the same either end. I suppose it makes it easier to see which way is which. The handle was also inspired in the moment. I took the looks right and shaped it by sight. The narrowest part of the handle is the same size as the tenon that is inserted in to the head. My only real design consideration!
The cup or base was turned and shaped with a bowl gouge. I finished it with a newly acquired Robert Sorby RoundSide Cut Scraper H24H. This profile is favourite of mine useful and easy to sharpen.
My wife has taken the gavel to school to keep order in the classroom.
My current challenge in wood turning is to make some trivets out of wood. The feature of the design is concentric circles on each face of the trivet. The overall size is 150 mm in diameter and 15 mm thick. One face has concentric circles that are radiating out from the centre. The opposing side has a group of three concentric circles. The cuts are made with a parting tool to a depth that is half the thickness of the trivet.
Small feet are turned from a contrasting timber. This has the trivet sitting off the table and highlights the details of the circles.
In order to complete this project I have construction a jam chuck. This will be constructed from 18 mm MDF. It is a 2 piece construction with a 2220 mm backing plate that attaches to the lathe. I used a 50 mm face plate but a wooden piece could be turned and glued to the backing place as a means of attaching it to the lathe with chuck. The jam chuck is nothing more than another piece of MDF approx 165 mm in diameter.
It is important that the jam chuck is centered on the backing plate. I use the point of a skew chisel to find the centre of the backing plate. Attached the piece that will become the jam chuck through the centre to the backing plate. Locate and drill two holes on the outer edge making sure that they are well outside the 150 mm diameter. Remove the centre screw and turn a recess 150 mm in diameter to depth of 6 mm. This jam chuck will allow the concentric circles to be turned on both sides.
The idea comes from an article entitled Heat Shield in the April 2011 issue of The Woodworker.
This bowl was made from a lovely piece of black wood. Not sure of the exact botanic name but it’s an Australian native. I have blogged previously about off centre turning. That post can be found here.
This bowl is better finished than the previous off centre bowl.
The first practical thing I have done since taking to turning. I have a picket fence with some plain fence posts. Capitals were the answer to dress the fence up a little After some discussion with swmbo I came up with a design to suit our place in Port Elliot, South Australia.
I have used the lessons learned in class and created a template after making a prototype. Each capital is 170mm high and 85mm at the base. I made ten so it was good practice. Repetition really does help with tapers and spheres.
The photos tell the rest of the story.
The pictures show the blanks being prepared and final photo is the collection of Capitals.
This is my first attempt at a three sided bowl. It’s an interesting experience turning off centre even with a blank that was little more than six inches square. The layout was done simply with a compass. Turning off centre is a little disconcerting and gets worse with each new setting until the shape is finalised.
The bowl dry sanded and finished with wet and dry paper. Red gum always comes up a treat and since commencing wood-turning I have come to quite like this timber.
This video from Robert Sorby explains the setting up and turning techniques involved in this approach.
I’m pleased with the result and it looks great in red gum.
Turned another bowl from the mystery spalted firewood. Consulted a local expert on the subject, it’s not eucalyptus that’s for sure. It doesn’t have any distinctive odour. So a pale quite light timber that turns reasonable well.
I was quite pleased with the shape of this piece. As always the shape was determined to some degree by what I started with. The opening is smaller and I guess that points toward future hollow forms.
This one is finished with the usual Ubeaut’s EEE and Shellawax. Thought about a lid this time but that may have to wait for another attempt.
