I paint my machines green because the wooden colour just doesn't visually contrast enough from all the other wooden things in my shop or the workpieces. Also, I don't care to emphasize that my bandsaw is made of wood. Primarily it's a bandsaw, wooden is secondary.
I wanted to stain the table to make it a bit darker so that when filming, workpieces stand out more against it. I rubbed some black paint on the table, but the result came out all blotchy and ugly. The small test samples I first tried came out much better.
So I started sanding it, but the table isn't totally even, so that didn't look great either.
So I resorted to painting it. Painting looks best, but that paint will wear through eventually. I put several coats of clear water based varnish on top of the paint to protect it. Ideally I'd have some piece of metal to go on top of the table, like I did with my jointer.
I don't particularly recommend staining or painting the table. Scuffs and scratches will show up much less if you leave it natural coloured.
I used some oil based varnish on the wheels and frame. Oil based is less moisture permeable, and that's important when cutting into green hardwoods because the sawdust can be wet.
For the frame, with the thick layers of cross grain lamination, extreme changes in humidity could cause those joints to fail. While oil based isn't enough to prevent humidity changes, it at least slows them down, which should help.
I put two coats on the whole saw, but more coats around the bottom wheel to protect against wet sawdust. But even so, if I cut green lumber, I always clean out all the wet sawdust as soon as I'm done. Even if your bandsaw isn't wooden, you don't want wet sawdust in your saw getting it rusty and mouldy. You don't want wet sawdust in a dust collector either.
Other parts varnished separately.
With the wheels varnished and the tires back on, it was finally time to balance the wheels. I put 22 mm roller skate ball bearings inside the 1" ball bearings in the wheels so that the small bearings could roll inside the bigger ones. The small bearings turn more easily so it's easier to find small imbalances.
I then stuck screws behind the tires on the light side until it no longer gravitated towards one side.
After that, I peeled back part of the tire, drilled pilot holes and countersinks, and put the screws in near the rim, hidden by the tire. Each wheel needed five screws to balance.
Screwing on the rear mount for the lower axle. On my 20" bandsaw I glued this but that is perhaps overkill. And if this one were to slip slightly, I could always adjust the screws that position the back end of the axle.
6" long 1/4" wood screws with washers hold the lower trunnion support beam. I enlarged the pilot holes from when I used #10 screws earlier so I wouldn't risk splitting the wood.
I also made sure the spot where that mounts on the frame was very flat so that it makes good contact over a large area for more stiffness.
Lower door going back on.
And the lower step.
L-shaped profiles to hold the upper wheel mount.
And with the upper enclosure mounted, I realized the upper wheel needed some sideways adjustment, in the yaw axis, to use airplane terminology. The back of the upper wheel mount bracket wasn't screwed on yet, so I forced it sideways with a small clamp, then screwed it on in that position.
The enclosure comes very close to the motor's pulley. That made the motor tricky to get on, and it took me three tries to get it on. The key is to nest the part of the enclosure behind the pulley with the pulley correctly and then putting motor and enclosure piece on at the same time.
A bigger hole for the pulley would have solved that, but I wanted the enclosure to be fairly closed around the motor because my motor isn't a sealed motor, and it pulls in the cooling air from the front.
Mind you, that motor came from a crappy old bandsaw, on that one it was fully inside the enclosure. It had a lot of dust in it before I cleaned it out.
Though it's possible to adjust the blade guides with the table in place, if I make more than just minor adjustments, it's less work to take the table off, adjust, and then put the table back on. It's not that difficult to take the table off and snake it around the blade.
And putting the lower blade guide cover back on. This part is key for keeping the dust inside the saw.
The wire for the switch runs through a hole I drilled through the frame.
The switch is wired into an electrical socket on the back of the saw. The switch interrupts the "hot" side of the lower of the two sockets, while the upper socket is wired to be always on.
The wiring for the bandsaw is almost identical to this remote switch, except that I wired one of the sockets unswitched.
I mounted the socket sideways on this one, figuring I'm less likely to bump into the plug that way.
And attaching the wire. I would have run it more parallel to the frame instead of diagonal, but the scrap of wire I used for this was just long enough to run it like that.
Assembled 26" bandsaw, between my 20" bandsaw and my 16" bandsaw.
My "big" 20" bandsaw seems positively modest in size now. All this for 6" (15 cm) more elbow room.
And finally trying out the saw again, first time running it since I took it apart a week earlier to start painting.
And as soon as it was together, Rachel came down to the basement to cut out some letters, similar to these letters, to go to the same family, for their second child.
But the hook tooth blade on that saw blade cut too agressively in the hardwood, causing a lot of chatter and bounce.
So she switched to my 20" bandsaw. The blade on that one is six tooth per inch instead of four, and much less hook and much less set. It's also in need of resharpening. It cuts a tenth as fast as the other blade can cut.
But the cut quality is much smoother. The extra cut time is more than made up for by time saved sanding. At right, right piece is cut on the 26" saw with the 4 tpi blade, left is cut on my 20" saw with the 6 tpi blade.
Part of what makes the 6 tpi blade cut smoother is that I had reduced the set on it a bit. This means it can't cut as tight a radius as the other blade, but usually that isn't a problem.
I ordered some different bandsaw blades for my 26" saw and wrote another article about bandsaw chatter and modifying the set on the blade that had so much chatter.
