I’ve been making wardrobes for a few years using primarily a tracksaw.
I started with marking pencil marks on boards to cut a square line, progressed through self-made jigs until I’ve settled on the perfect setup for me. I’ve got a tiny workshop which doesn’t have room for a fixed bench and I also like to work outside when the sun shines, and take my kit on site (i.e. somebody’s bedroom) when circumstances dictate.
The basics are:
2 sets of plastic sawhorses. One of them is a Stanley set which has notches in the top to fix 2 pieces of CLS.
2 long pieces (2.4m) of CLS, 2 short pieces of CLS.
An MFT top from Benchdogs and a set of dogs
A pair of UJK Technology Parf Dog Rail Clips from Axminster which keep the rail butted up against the dogs.
A self made fence (a piece of 90mm MDF with a 1m aluminium rule screwed to it)
This way I can support a 2800mm x 600mm board, trim both ends, make accurate, clean square cuts every time. When I need to make 7 480mm shelves, I just clamp a stop against the 480mm mark on the fence and lo and behold, I’ve got a production line going.
Naturally I’ve made additions to the setup, so I can clamp a board vertically if I need to use my plunge router, and so I can set my Kreg Foreman Pocket-Hole Machine in the run and still support 2400mm panels as I drill the holes along the length.
I keep looking at “better” alternatives but I can achieve speed, accuracy and flexibility here at minimal cost.
And I don’t use a sacrificial base, I’ve got 1 shallow groove at right angles (acts as a splinter guard) one at 45 degrees, and if I cut a bevel, I just move the dogs to a different position to protect the top.
