I have received several requests for the measurements on where to drill for the bolt holes. Now due to the lawsuit happy nature of the society we live in, a little disclaimer, a EULA of sorts.

End User License Agreement for dbhosts advice. My advice is free, and worth every single penny you paid for it. I am merely telling you what I did that worked for me, in my individual experience. By your reading my entries, you accept full and unconditional responsibility for any and all consequences of acting on any thing I have written down. Furthermore, you agree to hold dbhost faultless for any damages real or imaginary that may happen due to either properly, or improperly acting on his advice. Simply put, if you screw up, it’s on you, not me.

Now having said that, and covering my backside appropriately shall we continue?

My measurements are based on my Central Machinery #32208 14” 4 speed woodcutting band saw. Yours may differ, take careful measurements and make sure everything lines up. I have heard rumors, and casual observation seems to flesh this out that other 14” “C Frame” band saws are more or less the same. If you are modding a different saw, my measurements may not apply to your situation.

As has been illustrated in countless previous photos, the frame on the 14” band saw comes up in 2 arms that the tension mechanism rides in. The tension release lever mounts to this, and these are the arms I refer to here. If you have ANY uncertainty of what I am talking about, ask me and I will try to clarify what I mean.

The center points of the upper bolt holes are 10mm in from the left side of each arm, and 10mm down from the top of each arm. Once marked with a pencil, a good sharp, and HARD center punch is then used to dimple the cast iron, this helps keep the drill bit aligned and prevent bit walking.

The depth of the holes is somewhat critical, as they intrude into the channel the adjuster mechanism rides in. Drill until the bit just breaks the inside surface of this channel. Clean up any burrs with a long needle file to insure smooth operation of your tension assembly.

The left side lower bolt center is marked after the top is drilled and tapped, and the bracket is used to determine the center distance. I simple used a sharpie to mark the hole, and find the center.

Once the holes are drilled, and tapped, clean any thread cutting lubricant out of the threads with an evaporating solvent such as brake cleaner or similar. During assembly you will want to utilize thread locking compound, and the presence of the threading lube will interfere with that.

Hopefully I have given you enough information to keep you going in the right direction. Good luck with your band saw mods / builds… Have fun, and be safe!
