Shank question.

[captain_crunch]

they worn out frozen  wood Shanks junk at best

[JB Griffin]

They could have used a silver brazing rod. Not sure about the two piece carbide I don't remember seeing that before.

[Kbeitz]

I did some research and I disagree that these bits are garbage.
Well not in my eyes anyway but what do I know.
Looks like they are blue tip stand all bits.
There is very little difference between the new bits pictured and what I got.



 

[Jeff]

Blue tip standalls are not carbide. As said, your bits are worn out and not worthy of ever being used in a circle sawmill blade again.

[Kbeitz]

Ok... thanks

[grouch]

Still look like good prospects for that debarker you were talking about or a flycutter for a milling machine or several tools for a lathe. Could even be a tooth for a shaper, as in the Gingery shaper.

[Kbeitz]

I wish I had two 12" blades with a 2" hole that would fit my edger
That would take these bits.

I run the non carbide StandAll bits, it does look similar. They are good for low horsepower setups.
I think this is the bits you have, Dominator CT, they have a pic of them new

While on the subject of shanks and bits, I have a question.  I have a 48" saw and the shanks are labeled D-7.  I recall reading somewhere that this shank and tooth are obsolete.  Is this true?

[moodnacreek]

D shanks are discontinued. A  D style saw only 48 " must have been a top saw on a western mill with a larger D head saw.

Heres the carbide bits I run. A used up one is on the left and brand new one one right. Once they are sharpened back as far as the one on left all of your kerf is gone and time to be replaced.

That shows the difference... Thanks...

This is the first time I have heard that StandAll bits were good for low horsepower saws.  I understand they are good for frozen wood.  Would other sawyers out there agree that StandAll bits are good for low horsepower and why?  Do winter shanks have the same effect? 

[Ron Wenrich]

I'm not sure about the low horsepower aspect.  I always used winter shanks with standard bits.  Most guys in my area run that way.  I always had plenty of horsepower.  What the standall or the winter shanks do is lower the velocity of the sawdust entering the gullet.  Either one of them makes the gullet smaller.  Smaller gullets will fill faster, so you do have to slow your feed somewhat.  The effect should be the same.  

[moodnacreek]

            The carbide is brazed in a saw bit that has been machined to accept it. [ some are now cast for this purpose].   Carbide bits are like plow shares; they break when they are new or they last a long time. The ones shown are junk.

[bandmiller2]

Every mill I've ever been in has a can or box of old bits and shanks, sawyers can't seem to throw them out. I can see saving discontinued bits for something like an old Diston saw just in case, but not the common stuff. Frank C.

People try to sell em on e bay all the time.

Shanks For The Memories, what happened to KBeitz.  He had great posts and projects.

[petefrom bearswamp]

I asked Jeff if he was banned and Jeff said no.
Must be just that his nose is bent.
I too miss his input, wish he would come back.

[Jeff]

He is in self imposed exile due to his problem with how I run my forum. Too many good people here that need deserved attention to be concerned about him.

Sometimes a fella needs a vacation.
I switched to the standall bits on the advice of a sawdoc for my low horsepower setup. I'm just parroting what he said, don't know his reasoning. Just guessing that there will be less spill but that's just a guess. I'll ask next time I'm over at my current sawdoc's.

[moodnacreek]

Stand all bits cost more and take more power. 'Frost' shanks with regular bits do not take more power. Because you can't or shouldn't run stand all with frost shanks you can't run carbide either. But sometimes a saw won't run with regular bits but will with stand alls. When I ran a 52" style 3 with 50 hp or less It wouldn't edge a board with regular bits. Had new shanks and hammered twice by a real good saw man but it was stand alls or nothing. Never figured out why.  Currently  my 4 saws all have frost shanks and chrome reg. bits. I think the shanks should be chrome also but never went for it.
