Woodmizer blade

[Hayseed]

Has anyone tried the new woodmizer 747 blade. Suppose to be a good all around blade. According to the woodmizer sales guy. I am looking to cut white oak on my lt40 with 28hp gas engine

[WV Sawmiller]

   Never heard of them. Let me know how how they work out.

[John S]

I was told about them coming to the market but did not know that they were available now.

[Southside]

What are they? 

[terrifictimbersllc]

Sound like super turbos to me. 7 degree and 49 back angle. Just heard about them the other day. 

[kkennedy64]

They are not on the WoodMizer website yet.

[PAmizerman]

They are on the website now. 
I run 1¼ blades but the only 1¼ they offer are .042 thick. I've been running .055.
Y'all think .042 gonna give me trouble on hemlock knots?

[YellowHammer]

I think .042 will give you trouble in chocolate chip ice cream if you are having a snack attack and sawing fast. 

[Southside]

Is it me or did the prices go up quite a bit?

I spoke with a lady at the Paul Bunyan Show this weekend about the 747 blades. From what she explained, they will be very similar to the Turbo 7 Blades. They have had so many small motor mills like mine (25hp gas) running the Turbo 7 blades and like me when they get into a real wide cut they start to be horsepower limited. At 20" wide in soft maple, I could not keep the band moving fast enough through the cut and was getting the "ripples" of that are normal when cutting too slow with the T7. These new bands are supposed to remedy that problem and allow smaller HP mills to keep the feed speed where the band likes to be. 

This was my take away anyways, take it with a grain of salt as there was a lot going on at the show.

I talked with a guy from WoodMizer on Friday about that blade that was on the Lt70 wide at the show and I noticed the cant on the mill had the ripples for the first few feet then it was flat and smooth after that. He explained to me that the 747 would do the ripples if feed speed was slow and once the feed speed was increased to the sweet spot so to speak it cut flat and smooth. So as DWyatt mentioned “take it with a grain of salt “.

I got a box of them last week, .055 thickness. I plan on trying one out this week on a good size walnut log.
I will report back here with a video on it as soon as I get it on the 40. Should be by end of the week if not sooner, 

[PAmizerman]

@123maxbars can you get .055 in 1¼ wide? How wide of bands are you running?

[123maxbars]

@123maxbars can you get .055 in 1¼ wide? How wide of bands are you running?

I think they offer the .055 in 1 1/2 and 1/1/4
I am running the 171in wide head blades @ 1/1/4, after talking with @YellowHammer a few 
months  back before I got my new mill I decided to go with 
055 on everything, best blade decision ever, that Alabama fan sure knows his stuff 

[YellowHammer]

In my experience, whatever a .045" will do, a .055" will do better, at the slight sacrifice of increased fatigue failure.  An .055 will let you use all the engine power you paid for, will let you cut faster and flatter, but won't last as long on 19" diameter wheels.

Roll Tide!!

[Bruno of NH]

Do they make a .055 in 1 1/4 
If so I would like some for wide cuts.

[terrifictimbersllc]

158" 1-1/4 055 blades in 4, 7, 9, 10, 7 turbo are presently listed on the Wood-Mizer website. 

[petefrom bearswamp]

I have used .055 and .042 in many configurations but last used the 7 turbos.
They work fine but nothing will not climb hemlock kots

[Crusarius]

I just be happy if I could figure out how to cut spruce without waves.

4° band on the spruce or turbo 7°
