Title: Determining blade hook angle on used bands
Post by: newdesertfox on January 10, 2018, 12:13:48 PM
How do you tell what the hook angle is on a blade? I purchased a used woodmizer that came with 30 blades unmarked in boxes, I've spent plenty of time on google over the last 2 months trying to determine it but never had any luck, basically whenever a blade gets dull I end up putting new blades on at random and seeing if it cuts hardwood or softwoods better but its incredibly annoying. Is there any way to ID the blades hook angle before putting it on the sawmill or am I gonna be stuck shooting blind till I get them all resharpened and hopefully marked

There's been a lot said on the FF about that. Maybe this will get you started,

Many of the brands stamp the blade info on the blade near the weld, or at least WM and Lennox do.

For Woodmizer blades, you need "Blade gauge", part 065691, $15.00.  It's a hexagonal metal tool about 8x8" which has the teeth profile in each of 6 sides.  4/32, 9/29, 10/30, 7/34 are the ones I have plus two others. Does not have the 7/39 "turbo".

You hold it into the teeth and see which profile fits. Would also be good for checking grinding with non-CBN methods.
i'll put up a photo when the gallery is back up.

Never realized how much I use the Gallery.  :-\  I'll post a picture of that tool when the Gallery is available again.

Thanks, I'll look to see if I can find anything stamped on them. That tool sounds super handy, does anyone have a link to it? I tried googling it and I went through WM's website but found nothing

Thanks, from what I gathered you just have to call and order it as its not on their website. Found the WM markings near the welds, downside is the blades are so worn that 3 out of 4 I checked I can't read anything even after scrubbing the blade clean >.<

one other question if anyone knows, I found more blades with numbers, these blades are pretty clean in comparison to all the other boxes of blades (more blades have a good amount of superficial rust) but their serials are all similar, either Wood-mizer 2YGY137 or YGY126, I read the manual but can't make much of these, guessing their 13's but the 7 at the end, or 126 has me lost. Also when you send in to resharp, do the blades always come back shiny or if they are rusty do they come back that way? they didn't specify which boxes were dull blades and which were sharp so Im only guessing if Im putting worn out blades on the machine

If you have a login at Woodmizer you can click on "item lookup"  and enter that part number there.  it comes up as $15.00. Otherwise just phone in.  If you don't have a login you should get one as you have a WM mill.

There must be more than one URL for Woodmizer. I tried both the part
number 065691 and Blade gauge both and keeps coming up part not found.

If it is the search box you tried, it won't come up there.  I only found it in the item lookup , which I needed to log in to see.  Even if I am logged in, it won't come up in the site search box.

newdesertfox - you shouldn't have to "guess" which bands are sharp vs. which are not.  there are dozens of posts explaining what a sharp band looks like.

I figured it out today, as I said Im newer but what I didn't realize was the 3 boxes of blades I've been cutting with were all dull ones... so I've never worked with a sharp one to know haha, opened up another box that was clearly sharpened and it was like oh wow this is obvious...

I think you could get one if you called them. 

If you cant, and want one I can buy one on my next order, and send it to you.

p.s. you'll have to disable the Dremel Alarm on it.  :D

I found it once logged in on the parts lookup and ordered it, will know shortly if its the right thing, are there pictures of what it is? WM had no pictures

It may not be you Magic but i was thinking you kept a piece of blades to lay on top of another blade to match the angle.

I'd like to see this.  The one I got from Wood-Mizer several years ago is plastic, on a key chain.   One template for each blade angle.

Got exactly that in from WM using that product number, random question, what is the section marked 1 1/8   10? the tooth profile is very unusual
Title: Re: Determining blade hook angle on used bands
Post by: terrifictimbersllc on January 15, 2018, 07:31:07 PM
A blade I've never seen🎃🎃.

Maybe look it up on Woodmizer blades page.

Someone else will know.
Title: Re: Determining blade hook angle on used bands
Post by: Magicman on January 15, 2018, 07:38:19 PM
I have no idea either.  At the present time I only use two of the profiles; the 10° (white), and the 4° (green).  As my 10° blades are rejected out I will only have 4° and 7° Turbo's.  At that time I will have no need for the profile gauge.   ;D

WM marketed an 1 1/8" pitch blade for a while and may still do so.

This is the blade gauge set I got from Wood-Mizer.   I think I picked it up at Paul Bunyan a few years ago for about $9.   I only use 9º and 4º bands so I only keep those two templates on the key chain.

Finally had a rainy day to mark blades and came across a question... does the whole tooth fit tooth and gullet or just the tooth? I was marking out blades and they all seemed to fit the 10 degree side although the gullet wasn't fitting, and then after marking a few blades I randomly checked 4 degree (13, 9, and 7 didn't fit so didn't bother with 4 at first) and it also seems to fit although the 4 degree mark even the gullet fits -_- so how have other people used theirs and found the best effect? as there is a dig difference between a 4 degree and a 10
