Hello from Sydney

mardi 2 septembre 2014

Hi I am a lot more comfortable with a computer than I am with a saw table as I have learnt recently by losing skin from my fingertips. It could have been a lot worse and all is now good. I have recently been designing some new chairs for my house which I call Jonah - belly of a whale anyone? I did the design on the computer and had them cut by CNC from a sheet of Marine plywood. The plywood which I asked for (AA) and had delivered to the CNC service turned out to be only A quality and I had a lot of tear out from the bottom side of the cut. Spent ages sanding, grain filling and generally repairing the edge tear out with epoxy. Lesson learned make sure you see the materials you want to use before sending them out. The chair has turned out to be surprisingly comfortable and I am having it sprayed in a couple of coats of automotive clear to finish it. I need 8 chairs for outside and I think they will be probably be made out of Bamboo plywood for durability. I have heard that Bamboo ply also has problems when being cut a CNC machine. I have done a design for a more upright dining chair without arm rests and a matching table. I am going to make a Bamboo plywood prototype of the dining chair next to see how that turns out. Assembling the chair was fun and a bit like doing a Japanese wood puzzle. The rods holding all the pieces in place are carbon fibre as I did not know how strong the overall chair edges would be until I had one built one. Easily holds 120kg with negligible flex so thats another surprisingly good under engineered result. As you can see the facilities are a bit limited but that doesn't limit the imagination.



Best
