Better cutting & finish

cheyenne · February 18, 2009, 06:29:09 PM

I just be pondering before I fire up my new mill. On circular mills has any body ever put a 45 degree angle or radius on the corner of the teeth. I know it releives stress & leaves a better finish in milling steel. Seems to me it would work in wood.....Cheyenne

TCP (triple-chip) saw blades for table saws are similar to what you are saying, I think. They're only really used for really hard materials I think.

Try it, inquiring minds want to know. ;)

Gday

Yes It dose give you a better finnish on the timber but you also get an added bonus about 25% more horse power in the cut ;)

Downhere Alot of sawmillers just but the standard 60 tooth saw in the 36 to 54 inch dia range :

with little to no reguard for power needs or what they have avalable

:

that was one of the main problems i came up against when doing consulancy work Q why isnt my saw cutting rite A you have 60 theeth when you only needed about 40 ;) the reason i use to get saws settup as tripple chips was because i was dealing with new mills mainly and they had brought 3 to 6 solid tct saws to runn in rotation so instead of cutting them down and loosing the dia id just tell them just tripple chip em untill needed rebuilt then change them then ;) ;D as tct teeth cost the same either way ;) :D ;D I also prefer tripple chipping to skipp tothing a saw to gain hp per tooth

Ive done it to some of my Insert Bits that ive knocked a corner out of and it worked just fine but you have to get the angle spoton and centerd i do mine at the 45o mark but i dont think the radius would work too well Mate

We had a big, bad, beast of a table saw when I worked in the USFS Forest Products lab at UGA, and it's teeth had the beveled corners that you mention. Every other tooth was beveled, and between the beveled teeth it had flat-topped teeth that were shorter than the beveled teeth. It ripped very nicely, but the 10 HP 3-phase motor may have had something to do with that ;D

Thats a valid question I was going to say the saw will lead in the direction of the high side but the angles are alternating.Probibly Simons doesn't want to make right and left bits.would be an interesting experiment,but I'am not volenteering.Frank C.

Uhmmm....only one USFS Forest Products Lab, and it is in Madison, WI. ;D
There are research centers in different Regions of the USFS.

What is at UGA? ??? ???

I think the official name is the USFS southern research station. Not exactly sure. I guess if I hadn't capitalized "forest products" it wouldn't have been so confusing. Mea culpa. It is a lab run by the USFS that tests forest products, so I guess it could be called a USFS forest products lab :D
