Sawing Nails

Fla._Deadheader · June 24, 2004, 06:35:01 PM

  Today we were sawing Oak. Old Oak. Old meaning cut and laying around for a couple of years. Oak is NOT plentiful around here. Not straight Oak, anyway.

  Not long ago, someone posted about having trouble sawing knots.

  Where I am headed with this, is, this old hard Oak, was sawn with ease. Slow, because we use 1 V-belt for our blade drive, but, still sawn easily. Knots were NO problem. Nails, however, were plentiful.

It was 103° in the shade, and the heat index was 108.

  When we hit the first nails, 7 to be exact, I shut down the mill. Ed went for the hammer and chisels. We had a guy stop in looking for lumber, so, I took him to look at some. When I got back, Ed was sawing. I heard zip-zip-zip-zip. I asked him what he was doing??? He said it was too hot and too much work digging out the nails, so, I'm sawing them

He sawed all 7 nails, 3 times, that's 21 nail cuts, SAME BLADE ;D He stops, scrapes the burrs off the teeth and cuts another 2 X 12. We ended up sawing 280 bdft of 2 X with that blade and it still cuts flat and smooth.

I swear I don't understand how y'all tear teeth off yer blades, sawing nails ??? ??? ??? Clamps, I MIGHT understand, well, not really ??? ??? ;D ;D

Forget them metal detectors, getcha some Munks Blades, and just SAW them DanG nails. ;D ;D :D :D :D

Maybe I gotta move a few miles north.... weather machine said heat index was 112 this afternoon at 3pm. :'(

I've got a big pile of short oak limbs I can drive some nails thru if'n u need to practice your nail cutt'n... ;D sounds like your son's got it licked already.

I'm on vacation after the 1st so probably some time around then if your gonna be around the house..... actually I'd go up there also, but I don't think the wife would approve. Got her talked into buying a mill though. ;D Seems she wants a SYP chair rail in the house... whatever it takes right 8)

I talked to a guy that will be pushing over a windbreak of aust. pines this winter... says I can have as many as I want as long as they are gone before they are ready to sell the property.

Its an old grove that they want to sell the land off as 2 acre ranchets .. the aus pines have been there about 40 years... the windbreak is about 400 yards long.

Fla._Deadheader · June 24, 2004, 07:50:07 PM

In that case, getcha a Swingblade mill. Only way to cut that Aus. Pine. We done tried it already. :

;D

If ya wanna make some money, I got a buyer for 2 X 8's for trailer decking. Get $1.50 a Bd/ft. Work ya a deal. ;D ;D ;D

DonE911 · June 24, 2004, 07:57:48 PM

Now if I just had the $$$ to buy a mill everything would be wonderful.... actually they aren't comming down until winter, so no rush there...

Fla._,

What I find here is that if there is barb wire or nails in are hard woods ( oak and Ash) that the blade will go through them with out breaking the tips of the teeth off, but will have burrs welded on. With are fir or pine, the metal will take the teeth out. I figured that the feed rate for the hard wood is slower, so that just the tips of the teeth hit the metal ( less bite) and also the hard wood may be some support (backing) for the metal. I don't know if different brand of blades make much differents. I have used two brands of carbon alloy blades with the same results.

Does this match what you have in Florida?

chet · June 24, 2004, 09:04:09 PM

D., I would have to agree with your observations. Although a few weeks ago I hit a hardened pole barn spike in a hardwood log. Hardwood or not da blade was toast. :'(

Fla._Deadheader · June 25, 2004, 04:49:59 AM

"D", I believe ya got that figured out. That's why knots are not a problem in Hardwood, also, I believe. We can't saw real fast, (fast enough to hit the log stops and such, though), but knots in SYP will make you pull yer hair out somedays. We hit nails in SYP and STILL haven't broken more than 1 tooth on them Munks Blades. ;D :D

Deadheader,
About a month ago I got to saw thru a couple of sheet rock screws. No broken teeth just the sharp corner gone from some of the teeth. I switch blades & continue after removing the screws.
Following week I sharpened the blade & put it back on and ran it some more with no problem. Last night I sharpened the blade again & tomorrow it'll be cutting again.
Only time I have real problems are when I hit hooks 3/8 dia. they leave big chunks of metal fused to the teeth. They come right off though.

Question for you band mill operators, how long does it take to change a blade out? And how much does a new one cost?

Fla._Deadheader · June 25, 2004, 02:43:15 PM

I would guess the average cost is $20.00-$23.00 on the small mills.

Takes about 5 minutes to de-tension, change, and re-tension.

DR Buck · June 25, 2004, 07:21:06 PM

Ordered me a 2nd box of Munks today. 15 more blades in the mail. I sure do like the way they cut. Go right through those nails. :D But, no matter how hard I try, I can't get them to cut through the log dogs! ;D ;D

Fla._Deadheader · June 25, 2004, 08:57:34 PM

Ya gotta slow down a little. Give 'em a chance to eat. ;D :D :D

I had the same exact thing happen to me 3 weeks ago. An urban tree 30"dia at the butt. Rings added up to 113 years old. Nice tree beautiful crotch in it. Got the log all squared, took 2 boards from each side and was going to quarter the rest. First pass BANG

Hit a nail. I had to keep going. Hit another. Finally I was thru. I assessed the damage and looked at the cut. Not much difference ;D I will try another pass I told my father. Same thing. Long story short, I finished the log and totaled up 367bf. I was amazed 8) What blade am I using you ask??? Timberking Ultra. I have the tk 1600 and love it. I have made a few enhancements on it, but just love it. So I called TK and asked who their blades were made by? Guess Who! They are made by Monks(I cant remember how to spell it) MONKEY BLADES. I will never saw with anything else. Awesome blade and awesome Mill.

In Sweden they are marked "Munkfors Sågar".
One broke today, there was some more short brakes from the back side. Think I have to visit the Knowledge Base to night............... :

Swede,
Short breaks from the backside are indicative of the "back wheel" on the guide being too far away from the back of the blade.

If you are using guide wheels then they are set too far back.

The blade takes up the strain of the cut and is bent to the rear until it contacts the support of the "back wheel". If it doesn't reach the support soon enough, the body of the blade is stressed until it develops cracks along its back.

That is the only reason I know of where the back of the blade will develop cracks.
