CNC-ed Stools

Kenneth & Gabriel threaten to boycott me if they don't get a chair to seat on their next visit to my shop... :(

Buying chair for my shop use just isn't me... Too lazy to hand build some chairs... Procrastination sets in when it is a non-paying design job....

There must be plenty of free chair plans available in the net... so started strolling mindlessly across the WWW....

One will find when one seeks.
A nice stool design in the project page of 100kgarages. I like what I saw here and downloaded the free cad files immediately.

Unfortunately, I can't cut it as it was designed for 3/4 in thick Plywood but I only has 18mm thk MDF. Some customisation is require... but hey, having a free download already save me from loosing gallons of brain juice... can't complain over that...

Without further a do, open up the CAD file, changed the slot & finger joint size to suit the 18mm thk MDF I have, It is always a goof practice to double check the actual thickness for both plywood & MDF before working with it as they can very as much as 3mm... A good a verneer caliper reads 17.4mm averageof 5 readings...
To prevent any possible infringment of trademark of the Makers & the Shopbot, I  removeg their logo from the stool panels just in case & pop in some simple graphic pattern? The added bonus is reduction in weight :)

Then pop the modified CAD file into my CAM program, do some careful tool bit selection, tool feed rate, put in some tabs & G-code is ready for my Mighty Blue Beast.
Load up the MDF sheet, calibrate the positions, turn on the dust collector & I'm off for an extended coffee break.
The stool parts are completed & ready for assembly when I return...
As usual, everything snap-on perfectly.... ;)

This should make Kenneth & Gabriel happy on their next visit ;)...
