I live in a flat so space is at a premium and power tools are too noisy. I needed a way to re-saw lumber and found out about a “Roubo Saw” but all the kits seemed huge and clunky so I hummed and hawed about making one because my friend has a bandsaw… but now I cannot visit my friend because of COVID19_84 rules so I decided to make it.

I used MaFe’s portable frame saw as inspiration and after a few designs I settled on what you see here. The design intent was to make it lightweight, tool-less, compact for storage and usable on my small space (2×1.5m) so a 0.75m total length was chosen.

The long-beams are hemlock and the cross-beams are red oak. I used S4S lumber to ease construction, for the same reason I cut the slots for the blade and roughed out the mortises before glueing.

The blade is a 600x40mm rip-saw blade with the mounting kit from Dictum in Germany, gets mounted to the cross-beams via lynch pins and is tensioned with a cam lever.

The frame gets assembled with through tenons that are tight enough to hold it together but you don’t need a mallet to assemble or dissassemble; stainless steel washers reinforce the pin and cam contact points.

The blade stores in a slot cut into the long-beams and the cross beams dovetail into eachother, unfortunately I could not come up with a smart way to store the pins and cam.

Pretty nice, great design for compactness. Storing the pins & cam could probably be accomplished without too much additional work, but I would simply put them in a small cloth or leather bag with a draw string & tie it to the frame.
