LD60,

   Not sure of the details about your mill but with mine I'd definitely want 4 degree blades for the locust especially if it is somewhat or completely seasoned. Maybe the same with the maple. I can usually get by with 10 degree blades for the pine but if there is a lot of knots I drop back to 4 degree for it too. I have some 7 degree and 7 degree turbo blades but get little use out of them. Others use them exclusively so I need to go back and give them a better test run.

   Order a mix and try them all and draw your own conclusions. Don't let one log determine your choices though. Be sure the performance is based on the blade not one freak log properties. Good luck.

Larry, all the major band brands are good its just some mills work better with a particular band. I agree with less hook on bands, I like in the 4 to 6 degree range. Many manufacturers only offer 10 degree, nothing wrong with that try em. If your not going to sharpen your own best to get bands that they will sharpen, some will only sharpen what they sell. When I started I called many band vendors, explained what I was doing and ordered a couple of their bands to try, several sent me bands free to try. You will find your mill will like one brand and type of band best. Frank C.

As others said, try different bands. Over a short time you will know what works best on your mill.

LD60,

Congratulation on your build,   ;)     http://www.forestryforum.com/board/index.php/topic,90460.0.html

As others have pointed out you'll find which (manufacturer) you like best and provides the service you want/need, Shop on the left of the page
You'll have to consider how much H.P. you're pulling, what your sawing, hard or soft and how wide you want saw and band wheel diameter

 :P Good reading on hook angle, set and tooth pitch here.

Most homemade mil owners that ask the same question got the answer to use 4 deg blades.

So I need all the help I can get picking a good blade to use. I have a few big Locust logs and Pine logs and maple logs Please help Thanks

Over the last 2 days, I was sawing Black Locust logs to give the customer a bunch of 4X4X10's.

The 4x4's will be used to fence in a new apple orchard/back yard, against deer!

We sawed out 80 4x4's, 5 of them were 12', the rest were 10's.

We sawed 2 "short" days, each with one Wood-Mizer Double-Hard 10 blade that I had resharpened to 8.

These were fresh cut Locust logs, as we know, it does make a difference!

Using an abbreviated version of pi, I get 185.9 inches.  Good luck with the first blade!

Using Google calculator I get 185.690260418.  You have enough room to adjust .3 inches I take it?

... I have built my own mill.

Larry,

Have you purchased your sheave for your driven side yet??

The reason for asking is...  Proper blade speed (sfpm or surface feet per/min) is critical.  This needs to be matched as closely as possible to your hp/torque output of your motor.  To fast and it will lug the motor down and decrease the chance of having a good working and manageable torque curve while the blade is cutting.  In turn, this will make milling a less than pleasurable experience.

If you plan on cutting this winter, you are going to be working with frozen logs.  With that said...  A 4 deg. blade is the only way to go.  IMO and experience, it would be your best choice regardless. 

Hope this helps ya out

When designing a mill its best to start with a commonly used band length, like for instance a WM-40,  and build the mill around it. Also helpful if you have a wide range of adjustment. I would take ole Kbietz advice and stretch a tape around it, just to be sure. Company's that sell bands don't take you quite as seriously if you want an odd length band for a home made mill. Frank C.

  x2 on what bandmiller said. If you have to go with a custom length, keep in mind that the number of teeth on the band needs to be a multiple of 3 (left set. right set, and raker). Otherwise setting the teeth can get a bit confusing, especially with an automatic setter. Wherever you purchase blades, keep in mind that a blade normally will need sharpening and setting after just a few logs. Some blade vendors offer a sharpening service, some don't. As to which blades I am about as biased as can be. Woodmizer doublehard 1 1/4 by 7/8 tooth spacing, 10 degree rake 25 thou set. Probably not the absolute best in some cases, but good enough for everything.

Thanks for all the info on the blades. I talked with the people at Cooks We decided to try a couple of their Xcel black blades with 10 degree hook to start with they said that blade would work good on my mill being low on HP and cut all types of wood. It will be good to start with a cheaper blade while I get things adjusted and aligned up. Thanks for all the help again

For blade length, measure hub center to hub center...multiply by 2...then add wheel circumference of one wheel...which is diameter x's 3.14...

That's a conflict from all that I was told. Lower HP should be lower hook angle.
I was told 4 degree hook is best for low HP.

Kbeitz, I told them I wanted the 4 degree blade and she told me not to listen to them woodmizer guys and listen to her . Cooks doesn't sell 4 degree blades. So I will try 2 to start with the price is good also. I will give you a review when I get them cutting

I'm only getting my information form what I'm reading on this forum from
the experience of people with low powered mill that has tried different blades.
I ended up with a load of blades from the junkyard when I first started milling.
They worked great. Then I was ready to buy new blades. I wanted 4 degree blades
and the sales man said that what I really wanted was 7 degree blades. So that's what
I got. I'm not happy with the 7's My junkyard blades did much better but I have no idea
what degree they was. So my next order will be 4 degree blades then I can really say
what works and what does not. I do know that I had to reduce my travel speed by
1/3rd with the 7 degree blades to make them work.

I am all ears because I have only seen a portable saw mill operate 1-2 times and have never milled anything. I will get some 4 degree blades but to start with I don't want to have to order 15 -20 blades at one time till I make sure my mill cuts good and I can get aligned up.I watch and read a lot on here and trust everything I am told thanks everyone for the help I really do listen.
