Rick McConnell's bandsaw build

"V2" for a version 2 saw and I have made some modifications to it.Unfortunately I did not take pictures as I was building the saw. The bare frame after staining. I used pine shelving and it is a little thicker than 17mm so the frame ended up being about 1.7cm thicker. The finish that I put on the frame was supposed to be clear and it came out almost fluorescent yellow. I sanded it as much as I could and used a different product so it is not as yellow. It is a long way from what I was trying for. After getting the saw working I remade the block with the hole higher up. It was so much easier the second time having a bandsaw to cut it with. One drawback that I noticed to this design is that when you are adjusting the tracking you have to pay attention to the blade tension. With my block I have room to move up or down about 1/2", giving a blade range of about 104 to 106" in length.
Matthias comments:
The one-piece upper mount is certainly less work to construct, but it's not foolproof. I made the upper wheel mount a bit wider on the 14" bandsaw to give it more side to side (yaw) stability. Realized even more width would be better so changed it to be 1 cm wider in the plans. But the space between the uprights on the 16" design is larger, because it normally has the frame between the uprights and the wheel mount block.
Rick later added:
I built the frame according to the plans so the space between the up rights was very large. I ended up gluing a board on the inside and front of each up-right to fill up the space. The upper block is cut from a piece of firewood and it is about as large as I could get it, just barely cutting off the bark on one of the bevels. This also worked out for the tension spring strips as I thought the span for them might be getting a little wide.My shop has lower ceilings making it difficult to get the upper cover on and off. So I hinged the upper cover as you did with your 14" saw. I used a magnet to hold it closed. I built the lower cover according to the plans and used a magnet to hold it closed as well. I bought several blades, one of which is a Swedish Silicon 3/4" 2/3 tooth from R&D Bandsaws. It cuts real nice.
Matthias comments:
I see this is one of those variable tooth spacing blades. That prevents the blade from getting into oscillations in deep cuts, which should cut down on the loud squeal that bandsaw blades sometimes make while resawing.
The little door just pivots down and when the cover is in place the frame holds it to cover the slot, as you see in the photo. I modified the upper blade guide a bit. This allows it to be moved into the column without the need to notch out the column. Why brass knobs? Almost free at 25 cents each. When making the wheels I did not make the center hole large enough. So when I was gluing them together I could not completely eliminate the wobble. As a result the wheels are statically balanced but they have a bit of vibration when running. Remaking the wheels is on the todo list.
A week later, Rick emailed me some more photos:
I have made couple of more modifications to my saw.The first was to drill a 3/8” hole in the edge of the table. I then pushed a piece of 3/8” dowel into the hole. This keeps the table from flexing at the slot. The dowel is easy to push out with a screwdriver or even with the saw blade as it is being removed.
My cast iron 14" bandsaw has something like this as well. I thought about adding a way to lock the slot for my 16" bandsaw as well, but the table stayed aligned well enough without it, so it didn't really need that.
Rick continued...
I then installed a piece of channel in order to use a miter slide.I next added a rip fence. I found plans at americanwoodworker.com. Being able to cut the curved pieces with the bandsaw is supreme.
Looks just like the rip fence on Dejan Kovac's bandsaw. I had been thinking about building a fence for mine as well, but this simple resaw fence I came up with has been good enough for me so far.
