I am wondering if there may be a potential downside.....depending on the mite load in the donor hive(s). It seems you could lose the inherent "brood break" that a package provides if you donate brood...

tempered glass is great and tough, but it is "all or nothing" when it does chip/crack it completely disintegrates....that's one of it's safety features...no large sharp shards, but for an OB hive it...

After thinking about it some I have actually never bought a dado (except the wobble style) that didn't cut a flat bottom when new....so that alone would make me worry a weee bit about the overall...

It is going to boil down to the quality of the carbide. If all your using it on is pine, and your not running high volume production I think re grinding them will be fine. If you will be working...

DAniel,

the microwave technique you describe will destroy anything thicker than about a 1/2"....widespread checking and internal stress

Microwave kilns are great, but they still take much...

I had moderate success last year with a shop vac and brush going back and forth gently.
I also had some success with blowing a bit of compressed air across the frame with a slight angle toward the...

Ringshanks are great for lots of things, but their additional holding power is lost when driving into end grain as on a box. They are a still a good choice as they run a narrow shank and relativley...

IN a finger joint/box joint the nails provide the holding power in shear not in tension/withdrawl, and it works beautifully because you have a bunch of opposing members coming from both directions....

Never used or heard of their use in hives, but lots of folks use aromatic red (eastern red cedar) with no problem.

I have used both Alaskan yellow cedar and port orford extensively as boat...

Thanks again, the voice of experience is always reassuring (when it gives good news!) but appreciated no matter what the verdict

For future reference with AFB:
are the infected larva/capped...

Thanks oldtimer you are affirming what I had come to believe on further inspection and research

last years dead outs had no brood, and since I am new that was all I had to compare.
No scale...

I was dismantling a deadout from the winter.
tiny cluster, lots of stores, mediocre summer performance....no treatment....likely varoa/virus

the dead cluster was sitting on a few silver dollar...

DeKNow has it right,

After 20+ years of working these and other tools professionally....anytime I find myself rushing at the saw, or making a cut that is "just a little dicey but I will be...

density is generally inversely related to insulation value...meaning, more dense = ess insulating (greater thermal conductivity).

Paint will help, but I would just make sure you back up the joinery with nails in both directions(on each corner)...it will be fine even when/if the glue lets go.

Wood can get pretty bone dry in a heated shop in winter. If that is the case for you, it certainly could make problems when it swells back to equilibrium outdoors in summer. Working wood too dry can...

I wouldn't dismiss it outright. There is a heck of a lot of water on a good size tree moving up on a hot day. That water is being drawn at soil temp, which is a fair bit cooler than air in summer...

teak oil is generally a mixture of oils,hardening resins, and solvent. The composition aries by manufacturer but does usualy hae a good deal of tung oil in it.

We have had the warm spell blow in that much of the country saw. Came up to 49 today, the sun even peaked out for awhile. The last few days have been similarly mild, so the hives have had a chance to...

...or the middle of january to see if they are still alive?

How do you know the mouse is in there?
Is there enough moisture in the hive for a trapped mouse to survive???...obviously plenty of food.

Cleo, This came up in a thread just a few weeks ago and certainly you would need to account for the shrinkage in the construction. And you would have to use decent material...cut well clear of the...

roughsawn got used in a lot of older homes when mills were still more local for construction material and sheet goods were still unheard of. When you see those big flat boards come out of old...

one of the biggest reasons to dress the lumber is it is an opportunity to level it. Most material will cup to some extent as it seasons, the planer removes that cup allowing for more precise and...

If you have to buy 8/4 rough to yield 3/4 dressed you really have to find a new mill to do business with!
A good mill will saw 4/4 to 1 1/16-1 1/8" when measuring the "fuzzies". exact 4/4 is...
