Title: Ok my first post again ,question about bandmill blades
Post by: zombie woods on January 24, 2013, 07:10:51 PM
Jumped the gun and posted over on the forestery side of the forum ,
was kindly directed over here .
Greetings to all ,
Quick introduction
I salvage timber , started in southern Africa back in 1986 set up my log yard in here in homestead florida  back in 1990 made trips back and forth yearly ,
then in 92 Andrew hit and I started salvageing local subtropical timber primairly cuban mahogany ,lycaloma /wild tamarind , jamaca dogwood , womans tongue etc .
as it became increasingly dificuld to deal with U.S. customs I shifted more to local salvage ,
as with most urban salvage  tramp metal is a real problem , 60 years on a street corner in  Miami and its sometimes a tough choice between takeing the bole to the mill or the junk yard ,
and the African timber blackwood ,pinkivory etc is just plain hard .
Seems at times I spend more time sharpening and setting than I do milling .
Tryed all sorts of blades and configurations  the blade that I think is far superior right out of the box is the inch and a quarter Lennox woodmaster c , 0.042 , 7 degree hook, set from 0.022 to 0.030
problem is I cant find a cam to grind the lennox profile ,
I am using a the old Woodmizer automatic drag sharpener , any one fabricating custom cams ? Runing a WM lt 40 35 hp cat .

I have tryed the wm razor tip odd concept stelite tip on a set tooth
expensive to buy and expensive send in for resharp ,
havent tryed to resharpen on my machine yet .
suspect that sliver of stelite is good for about 2 or 3 sharpenings max .
they cut good about 40% longer than wm double hard in my initial estimation ,
at 80 bucks per and $12-14 to resharp plus the shipping
doubtfull about the long trem r o i .

Welcome to the forum. I would take the cam to a local machine shop and see if they can build one like it. If they can they should be able to make one a little over sized that you could shape the way you need to on a bench grinder or belt sander for metal.

What shape exactly are you trying to match ?  Woodmizer has the flatter gullet. If you are trying to match a more curved gullet, just carefully watch the cam action as it lowers the wheel. Take a piece of chalk or soapstone, and mark the cam at the point the wheel first makes contact with the gullet.

Then watch where it lifts off the blade. That will be the section that you grind away a little at a time, to allow the wheel to drop further down into the gullet.

We used strictly Munksforsager blades, 1¼" x .042 at 10°  and also used Woodmizer 1½" wide blades. We cut several types of "old country" logs that were brought into South Fl by immigrants, then got too big too close to their houses.

It would actually chatter as it was cutting on one particular type RED colored wood.

Check with Menominee Saw in the Sponsor side of the forum, or Kennesaw Co. in Kennesaw Ga for a trial blade.
