While this is not made of wood, it is for woodworking.

I had made router bit storage of wood, or wood by-products. Today I discovered what a mistake that was. Corrosion!

Storing router bits should not be made of material that is sensitive to moisture, or humidity. I had made mine of some scraps I thought was good. However, it is not.

You can buy plastic sleeves or do this . . .

I cleaned up my router bit shafts, waxed them up (parrafin or Johnson floor wax works) and made my holders of the green styro found at Home Depot. Gluing layers/levels together with a little epoxy.

I drilled holes in the styro smaller than the shanks. E.g. for 1/2” shanks I drilled a 3/8” hole. Makes good snug fit. Drilled 1/4” for 5/16 shanks, 3/16 for 1/4” shanks. Works same for smaller diameters. Does it get smaller? Perhaps for Dremel tools. Works best to drill on drill press as you get less tear out.

Very interesting. I suppose that it matters that the shafts were “buried” or “embedded” in the wood so the raw end grain could “breath” right on the steel.

All those wooden tool boxes with all those beautiful hand planes setting on the surface of the wooden supports are probably ok especially if there is a bit of sealant on the surface. At least I’ve never noticed any problem.

DeSwede, this really gives you something to think about before making that new bit holder. Thanks for the alert.

The wood species is important. Some, like red cedar, is particularly prone to creating rust where it contacts the wood.

I built my router bit storage with hard maple … never have had a problem in 5+ years.

I have my bits in a piece of Baltic birch plywood and no problem with corrosion but our climate has relatively low humidity year around but waxing the shafts of the bits is a NO NO in my opinion as it may cause slippage of the bit in the chuck .

Great advice from everyone! I won’t be waxing the bit shafts! Good thing I haven’t yet.

Great exchange. Thought I was giving a good tip, yet got some really great ones from others and saw errors of my way.

I used hard maple and sealed each hole (drilled 1/16” oversize) with polyurethane. I keep my basement dehumidified and have not had in problems in over 20 years.

I drilled holes in pine that I fit into a sealed plastic container about 4 or 5 years ago no problem

-- I cut it three times and it's still too short
