When I mounted the bearing mount to keep the cutting blade vertical on my home table jigsaw, I didn't worry about having no space behind the blade to make straight cuts with the jigsaw. Anyway, I did not plan to make those types of rip cuts with this saw. But as many of you ask me how to cut straight with the tabletop jigsaw, I wanted to try putting the blade holder sideways.
One of the advantages of the bearing bracket I use is that it is very easy to remove and attach. So I unscrewed it, presented it sideways glued to the back of the blade, and marked on the board the position I wanted to put it in.
I put the base of the bracket as far away from the cutting blade as I could, so that it had room on the side to screw in the little bearings. And if you look at the photo, the gap between the stand base and the cutting blade is the maximum width that I will be able to cut. And although it does not seem very certain that it is sufficient for most cuts.
As the bearing support protrudes a lot laterally, I placed a thick wooden block just below the position where the support with the bearings will go, so this block serves as a platform for that support with the bearings that guide the cutting blade. This I put under the tabletop, and screwed it to the table frame and the tabletop. In the video you can see how later I had to unscrew it to be able to move the tabletop, since it needed to have a bit of an overhang at the front to hold a makeshift lateral guide with a sergeant.
On top of the wooden block I screwed a piece of plywood to have a platform with the surface level with the table top on which to put the support with the bearings.
And since I didn't find the other matching bearings, which I know I have somewhere in my messy carpentry shop, I unscrewed the bearings from the front of the bracket. I measured the clearance I need between the bearings, drilled a couple of pilot holes, and screwed the bearings into the side of the housing in a suitable position so they can guide the jig saw blade smoothly. Although as you can see in the video, I had to remove one of the bearings and relocate it, since it had left them too close together and they did not leave enough space for the thickness of the cutting blade of the jigsaw.
I placed the bracket with the bearings laterally, with the cutting blade between the bearings and its back resting against the plywood. I adjusted its position so that the cutting blade is perfectly vertical, ...
and screwed the bracket to the base that I made next to the board.
And with a slat fastened with sergeants, as a lateral guide, I was able to try making straight cuts with the jigsaw. Straight cuts in plywood are easy to make.
But cutting straight across, to the thread, in solid wood like pine, is another matter. Making these cuts straight is difficult for this jigsaw. And the cutting surface, although straight, is horrible. Some of you tell me that perhaps, to cut straight with the jigsaw and in line, I should find a suitable blade for these cuts, so I will have to look.
