Old habits are as hard to break as the old myths that fed them. Or to almost paraphrase an old Tina Turner song, “What’s Lead Got to do with It?”

Of all of the things there are in your mill to adjust to keep your saw running properly, lead is not the one you want to mess with.

I don’t like the knock in the bearing, so it is good that it has
been resolved.
I am more concerned about endplay, than I am about movement
up and down.

Sawmill Forum - Trends
01-01-2010
Trends from one saw doctor’s perspective.
2009 has been a tough year for the lumber industry, to say
the least. I have seen many of my customers slow way down,
close their doors, or go out of business.

Sometimes my circular saw just doesn’t seem to run properly no matter who hammered it or when it was done. Where do I start?
12-01-2009
The three most important things to check first when having saw trouble are sharpening, sharpening, and sharpening.

One of the questions I am asked most is how long a freshly hammered saw should last.
11-01-2009
My standard answer is that if the saw is running properly when
you first put it on after being hammered, then the length of
time it will perform properly is directly related to how you
and your mill decide to treat the saw.

I just wrecked my best saw. I have heard that you can’t weld more than three shoulders in a row or more than six on the same saw.
10-01-2009
When it comes to replacing broken shoulders by welding new ones on, there are a few things we have to consider.
1. Safety.
2. Accuracy and effectiveness.
3. Cost effectiveness.

Scragg saw blades both running out of the log.
09-01-2009
Scragg saws operate on essentially the same set of principles that any other circular head rig operates on. You need saws that are sharpened accurately and hammered correctly with the log side flat, an acceptable amount of wobble and the right amount of tension in the right location. After that you need the right amount of lead in the saws and you have to have good collars that support the saws without dishing them one way or the other.

Sawmill Forum: After close inspection of the log and the blade I discovered that one of the teeth had broken off and embedded in the log long enough for every other tooth to slam into it. On close inspection, the point of the shoulder (that’s where the ba

My basic philosophy about welding these saws it that it is best to avoid it if possible. It’s not that I mind welding saws or making money, though.

Sawmill Forum I discovered that the shaft broke right inside of the third of four bearings. Should I have it welded back together?
07-01-2009
Knowing that the pins are supposed to shear first, let’s see
if we can solve the mystery of why the shaft broke.

The simple answer is to screw up your courage and open the throttle up to your normal speed. You will be amazed when that crazy wobble disappears.

Sawmiil Forum - One of my saws just doesn’t seem to run right.
05-01-2009
I have checked everything I could think of in the mill.
The track is straight and I had the collars redone and
I still have trouble with that saw. My other saw seems
to run okay. Do you have any ideas?

A saw doctor’s advice to a good friend who was recently diagnosed with a treatable, yet very serious form of cancer.
04-01-2009
This advice should apply to anyone in that position, but I warn
you, taking the advice of a saw doctor about medical issues
does not relieve you of the responsibility of consulting with
medical doctors. I should also warn you to never consult with
medical doctors on saw related issues.

Sawmill Forum Working on 60: Saws
03-03-2009
I have been hammering saws for a number of years
now, but every time I do a 60” saw, I seem to have
trouble with it and much less confidence in the results
than with smaller saws. What am I doing wrong? Are
60” saws that much harder to hammer?

When I first started hammering saws for a living, it was quite

be a big secret.

When it comes to smithing saws, can you do it all with just a stretcher roll? Is there any need for a hammer?
