Shipping Bandmill Blades

A bandmill operator got some blades back from the resharpener with broken teeth. Were they damaged in shippping? August 31, 2005

Question
I've been sending blades out to be re-sharpened. I'm pretty sure that when I sent them, they were in good condition. But my sharpening service rejected 3 of 14 blades, saying they had broken teeth. I got them back, and sure enough, they did have missing teeth.

I suspect that the shipping process (Fed Ex or UPS) may have contributed to this problem. I suspect that handling of my package was pretty rough, and that the way I had the blades packed, maybe they got knocked around inside the box and broke a few teeth off.

When I pack the blades, I curl them up into three rings, and put one blade tooth side down, and another blade on top, tooth side up. Then I put in a piece of cardboard the same size as the box, to make a nice stable platform for the next set. I continue sandwiching them this way until I fill up the box. I can get 14 or so blades into the box this way.

Has anyone else experienced this problem before? Does anyone have any recommendations on how I should pack the bands up inside the box to avoid this? Should I just find a local guy to do the sharpening for me, or should I plunk down the 2 G's for an auto-sharpener and be done with it? I don't have the space for a sharpener in my garage, so I'm leaning away from that idea.

I'm presuming that you are trying to ship in cardboard boxes. I have had new saws shipped to me the same way and have had the same problem when they arrived, and these came brand new from the manufacturer.

My way of protecting saw blades is to make my own saw shipping/storage boxes. For example if you were shipping 10"-12" saws, build a box 4" tall with a 3/8" plywood bottom. Use 1" x 4" s4s boards for the walls, screwed in from the bottom for strength. The lid will not be the same dimension as the bottom, because it will need to adjust from the top down into the box to accommodate the amount of saws that are being shipped.

Drill a 1/2" hole in the center of the bottom and the top. Insert a bolt from the bottom that goes no higher than the top of the walls of the box. Now you can replace the lid, put a washer and a nut on top to secure the saws in the center of the box.

Always consider the amount of weight the box is going to carry. This is why the people handling the boxes drop them and break the teeth, apart from the saw being unstable because of inadequate packing materials.

I store and transport my blades in a flat box about 1 1/4" deep up to 20 blades per box. A "C" shaped iron clip keeps them together in a configuration similar to that of a pair of eyeglasses. I works much better than shipping coiled.


From contributor K:
I ship my blades to re-sharp the same way you do and have never had a problem. At any given time I have 40 to 50 blades in the system.

What I do is mark my blades. All my blades have an "A" engraved with the number of times it has gone to be sharpened. When the blades come back I check to make sure they are all mine. Only once in four plus years has there been a problem and WM made it right. Maybe you did not get your blades back. It would take a good jolt to bust a tooth of a blade inside of a cardboard box. It seems like a bent blade would be more likely.



From contributor L:
I suspect the teeth were broken during the setting process.


From contributor M:
I would suspect that it happened during the setting also. I ship mine coiled to Cooks, they send them back the same way, and I’ve never had a problem. I don't even put spacers between them, as Cooks does when they came back.


From contributor E:
If the teeth broke from being dropped, think what would have happened the next time you sawed. I'm pretty sure a blade goes through a lot more abuse hitting a log than it does being loaded on a truck. We run our blades basically until re-sharp rejects them or they break, so out of a box of 20 we typically have 3 or 4 that are too far gone.


From contributor N:
In removing a blade, if I bump it against the frame of the mill does that create enough force to damage the tooth? I do have access to a sharpener so I am thinking reject blades can be sharpened at home and used on low grade milling like fence post stock until they break.

Where can I go to get a tutorial on teeth? The principles are simple. On chainsaw work this works if a tooth is severely damaged by hitting a rock or nail I'll just file/grind that tooth hard and leave the raker high. I have only done this once, but it got extra life out of a loop of chain cutting brush.
