Making a Leather Sling Back Chair entirely on the SmartBench CNC

- In this project, we tackled various cutting strategies on the YetiTool SmartBench CNC to make this hardwood leather sling back chair entirely on the machine itself.
We used 2400x110x12mm Vic Ash panels to cut the parts of the chair. 4 segmented parts created each limb of the chair. 6mm dowels helped locate parts whilst glueing.
We then used a drag knife to cut the beautiful 4mm Australian tanned cowhide from Austanners in Geelong. The drag knife cut through this thick vegetable tanned leather like a hot knife through better in a single pass.

We then processed a few acrylic templates for our buckle and strap ends for the the leather sling, to help us mark them out before punching.
The chair came together and was given a generous radius on all edges thanks to the Carbitool 12.7mm radi rounder bit, mounted in the router table we made in a previous project video.
The chair came together beautifully. The accuracy on the finished wood parts meant little sanding was required after glueing, and the leather sling was cut to exact dimensions from our design in CAD. The SmartBench CNC allowed us to take a very complex design from CAD, to CAM to a finished beautiful piece of furniture!

Beautiful. Thanks you for sharing your process. I’m looking to build a similar chair.
Thanks for following along. Hopefully it gave you some inspiration for your own project. We thoroughly enjoyed doing this project ourselves from start to finish.
I am guessingit's not good for cutting fabric right?
Depends on what type of fabric. Standard fabrics like cotton, etc. won't work well as they will just shift and move instead of cutting. Anything with some weight to it such as leather, heavyweight canvas, cork, etc will cut no problem with the drag knife attachment.
Hi, what minimum and maximum thickness of leather can we cut ?
Thanks for watching! The drag knife comes in several different offset options. The tip of the blade is offset from the centreline of the holder and will dictate you minimum inside radius on corners. This in turn also dictates the thickness you can cut.
The version we used in this video has an offset of 3mm, and we cut 4mm leather suing this one no problem. The downside is the tightest corner you can cut is 3mm.
You can cut anything down to thin vinyl with this offset, but you can't do sharp inside corners for instance. We carry drag knives with 1.5mm, 3mm and 4.5mm offset to cover anything from thin to thick.
The 4.5mm version would tackle 6mm leather I suspect, going by our results with the 3.5mm. We also have an adjustable version which covers all these ranges and uses a standard Stanley knife blade. You can see more here;

I hope this helps!
yeah very nice video, but please skip the "music" in the future, very annoying I.d much rather hear spoken comment or even the sound of the machine or some background info during the video would also be nice (what material, what tools, which software etc) Kind regards Hans
G'day Hans, thanks for watching along! I'm glad you were captivated enough to watch despite your distaste in the music selection. Perhaps a silent viewing might be more to your taste, I can't promise I won't keep my terrible taste in music in future videos!
Music was a nice touch mate!
Each to their own.
God awful background musac.
