Cutting out the pivot slot with a router. I'm using a four-sided held to the table to guide the router.
Here's cutting the ledge for the table insert with a router. The green square clamped to the table helps to guide the router for a linear edge along one side. I recurrent this for every side of the table cut out and then chiselled the angles square to finish it up.
Here's the table support attached to the base of the table.
The table sustenance for this saw is unusual, in that it comes about the right in its place of about the left. On furthermost saws, the forward-facing trunnion sustenance reaches over the space bounded by the lower wheel on the base, the blade on the right, and the table on the top. But the lower blade guide also want to fit into that space.
With this band saw actuality a comparatively little 14" band saw, and wanting to mount the table as low as possible, there simply wasn't sufficient room for everything. So I decided to move the table mount to the right. This in turn means that it's impossible to eliminate the blade on the right side, so I moved the slot for the blade to the left side.
My first idea for locking the table tilt position was to create a link as shown. This link would pivot on the base of the table, and get locked in place with a screw and washer against the frame. I got as far as this photo when I decided that a slice of wood with an arc-shaped slot would be a simpler and better solution.
So this is what I made instead. It does require cutting a curved slot, but other than that, this is a simpler design. I cut the slot on my scroll saw, although it could be cut with a router as well.
The table support bolts to the frame using three bolts through the frame.
Wood screws would work just as well, if not better, to screw the table support onto the frame. But for motives I'll get into in a future article, I want this table to be easily removable without wearing out the screw holes in the wood.
Here you can see how low the table is mounted. There's only a few millimeters of space between the top of the wheel and the base side of the table. With the table sustenance attainment around the right, there's still sufficient room for the blade guide below the table.
Creating a table pullout is as simple as sliding a slice of plywood into the insert space while the blade is running. I also made an insert for beveled cuts.
The hole is extensive enough to‐accommodate the blade up to a 45-degree tilt. This is the main disadvantage to using pivots. By using trunions to tilt the table, one can have the axis of tilt level with the top of the table, which eliminates the want for a wider hole.
Inserting the blade is done from the left, not the right. Once the blade is slid all the way to the insert hole, it's rotated to the left to bring it to the wheels.
I figured the tracking should be good sufficient to permit the band saw to be used even without guides, and this confirmed it.
