A simple baby chair

Come babies come the need for a high chair. Fisher price plastic booster seats were an option but I have the habit of saying "I can build it so no need to buy it" for many things
my wife proposes so this time I had to actually get down to doing it. I used one inch block wood.

A few curved cuts with the jigsaw gave this a 'modern' and quasi professional look. Those who have not used a power saw may think that curves are tougher than straight cuts. How ironic! Two flat pieces served as the base and the back, fixed in with one and a half inch wood screws fixed in with guide holes and counter sink holes.
I do not know more about the wood other than this. This was also some left over wood from home

carpentry. The teddy bear 'Mr. Fundoo" served as a dummy for the project.
To get the legs I cut a long piece of block wood into two inch strips using a jigsaw. A circular saw would have been more useful but I did not have one at this point in time. The cuts were not very straight. These were then fixed with nuts and bolts at an angle on both sides of the chair.
A similar piece served as a cross bar in the front and the back. The chair was a bit wobbly. A little b it cut out from one leg and then another ensured that it was stable. However one thing I noticed was that even professionally made chairs were wobbly as my floor itself was not perfectly level.

Once the whole chair was assembled, I dismantled it. Applied insecticide, primer, putty and then paint in that order. We used purple and pink for the final colors. I then reassembled the pieces.

For the surface a transparent PVC sheet was used. This is expensive stuff but I had a piece lying around. A curve was cut in for the stomach of the kid.


Around the edges I fixed some PVC beading that provided a raised edge. I screwed the beading in from the underneath in addition to glue. To ensure a fit I used door magnets attached to the sides of the chair. It was
possible for the kids to kick off the plate and so I attached a hook at the back of the PVC surface that fixed it on the chair. Now my kids do not kick of the hooked surface. They first unhook it and kick it off.

However this serves the purpose. They cannot be left unsupervised on the chair as they can get out of it.

I have also not go the time to fix a harness or belts on the chair for safety. But it works.

This piece was simple to build in regards to skill. There are no complex joints or cuts. It just required patience, patient family members and attention to detail. I did replace the iron nuts and bolts with stainless steel ones later on.

For my second child we bought a fisher price booster seat. I know I could build it ...

Wooden plaque


One of the first (well of only few) woodworking projects that I undertook. This was planned as a gift. It was three years in the mind and about six months to make as I worked on it in very small bits of time and redid it a few times.
It is a verse from the Bible (Psalms 33:11)
The base was Vengai wood (or Irulai wood), I do not remember. The wood was a little larger than 2x1 feet and 1 inch thick. I got it from a local lumber mill in Vellore. I got the surfaces planed in the mill itself. (The wood looked horrible initially and I was quite disappointed as this was my first wood purchase. The grain was revealed in all its beauty after planing). The curved edges were cut with a Skil Jigsaw. I somehow thought that curved irregular edges were more appealing.
The first thing that I did was to apply some pesticide like chemical that my local dealer told me about. I applied this with a brush.
I wanted a dark background and so I stained it with rosewood stain. This was applied with a bit of waste cloth in about two or three layers. The grain became more pronounced, but the finer details were lost. It however got a richer look.
I must mention that as this was my first project, I experimented a lot and had to redo things many times. One of the first things I did was to apply sheenlac wood polish over the stain. To my horror all the stain came off. So hey presto, I had to remove the whole thing and do this all over again.
I then tried some 'sealant' that someone told me to. The stain came off again. It was back to sanding (with a Skil orbital sander) and reapplying the stain all over again.
I finally used clear varnish. All my heroics were in the balcony of my studio appt, out of the sight of my kids and ensuring that the smell did not overwhelm the whole house.
I read off the net that one has to sand the varnish and reapply. So I faithfully did so. Varnished and sandpapered it. With fine sand paper 400 grit (the finest that I could get locally).
However a horrible problem that I faced was dust settling on the varnish. Dust, insects, leaves you name it all had an uncanny ability to land on the freshly painted piece. It actually looked better after the sandpaper. After sandpapering even with 400 grit the sanding lines were visible. I thought I would use some solid wood polish to get a final luster. However this did not provide the finish I wanted and after two or three layers of polish I realied that what I had was a finger print magnet. I wanted to remove the polish. I could not. So hey presto back to square one to my wife's disbelief. Sanded, and repolished etc.
Finally after about six or seven coats of varnish the base looked good. There were a few dust spots on it but I could never get a dust free environment. So the dark base was made.
To get the thin wood for the lettering I used a light colored pine veneer that another local plywood shop had a bit of. However this was too thin and the color was not to my liking. Besides the letters did not cut fine. I thus stuck a light colored laminate over it with fevicol. I had some left over pieces of this laminate from some carpentry work done in my parents house. This laminate plus veneer was thick enough and cut well.
Well now to the cutting. I always thought this would cut fine with a hand held 'U frame saw' or a 'fretwork saw'. I purchased one for about fifty rupees. But lacking a vice, and holding the piece of wood in one hand and trying to use the thread like blade to cut out a letter was almost impossible. It took me about half an hour for a letter, and the blade broke numerous times. It was frustrating. I wished I had done the letters first.
I looked up scroll saws. There was a Skil scroll saw available in the US for about 100 dollars. It was not available in India. The local hardware supplier did not have any idea what it was for. When I described what I wanted to do I bystander said that 'Sir, that is professional work, you cannot do it...' or something to that effect. This only furthered my resolve.
I finally got a workaround. I purchased some scroll saw blades in bulk from a hardware store, and converted my skil jigsaw into a scroll saw. To do this I drilled a large whole (about half an inch in diameter in a long plank of waste block wood. I dismantled the jigsaw and fixed it over the hole so that the thin blade would pass up and down through the hole. I then used this as a scroll saw. It was crude. The blade bent easily, broke easily but was way more effective than doing this by hand. I was able to cut the letters out with this arrangement and prepare them for pasting.
After all the letters were available I pasted them on with fevicol. I was aware the fevicol was just sticking the letters on to the last layer of varnish, and with time this would fall of, so these had to be nailed down. I used thin headless nails.
Now hammering a nail is an art. Every second nail bent. Some and to be broken halfway. A few of the letters split and had to be hammered individually. Eventually the whole thing was assembled. Two hooks behind and A GI wire between it helped to hang it up.
This piece was designed keeping in mind a similar piece that had been designed by uncle Ian Robson from Bangalore. He is one of the best professional woodworkers I know. I tried to copy his finish and his attention to detail. His carpentry has survived in our home for twenty years and is still as good as new. Literally. I have only childhood memories of him and the work that he used to do, and we have kind of lost touch, but hope to renew our friendship some time in the future. Thanks uncle Ian for these wonderful memories.
