I bought a Wolfcraft Jigsaw Table in July 2013. After purchasing it and finding that the Jigsaw Blade wandered about it made sense to buy a blade guide arm. Wolfcraft used to make one but I couldn’t find one for sale. Using the metal from an old sofa bed frame I made a guide arm with roller boot wheel bearings to guide the saw blade. The final result, crude as it is, can neatly cut wood as thinly as 1mm.
