Thanks for the pictures.  I would like to know more about the technicalities involved with circle blades.

I installed the blade last night and tried to cut one 3x12, it made a big difference. It was still out a little but I have to take some lead out of the saw, Im thinking once I do that Im gonna be bang on. The saw doctor also put new teeth in for me, he told me just to use a soft tooth for now until I get the hang of sharpening. If it dont rain today I think I will have a few straight boards coming out of the mill. That will make me a very happy camper!!! 8)

Did he give you advice on your collars?

And pin holes?

I had took down the outside collar to show him, he said that was a pretty thick collar and it was made flat with no tapper to them. He told me to leave them as they were. He said he saw flat collars before. The pin holes he told me to just take a die grinder and make it fit, as long as I did a little at a time it should be alright. When he orders new blades he gets slotted holes.

The saw doctor told me lots of stuff about the blades, its hard to remember all that he said. He basicly hammers out the imperfections. His basic tools were a hammer, straight edge and some chalk. In the last pic where the sablade in laying flat. that is a press, he said it saves hours of hammering.

Ya know I have one of those hammers I got in a pile of stuff at an auction and never really knew what it was for for some time .Makes no diff. really because I wouldn't have a clue what to do with it anyway .

I got hammered a couple of years ago.  My better half  was not to happy.
How in the world do you learn a trade (art) like that?
Nice post.

How in the world do you learn a trade (art) like that?

Usually you are taught by an old master, man to man, face to face. And then by experience...

I was givin a book on hammering circle saws years ago and at that time it was a dollar a inch. So I bought me a straight edge had a nice 10 inch square anvil. I hammered my 54 inch and put it on the mandrel [ befroe I go any further it looked like a million bucks ] This mill had a old flat head straight eight Buick engine and the whole dash was cut out so you started it with the key. I put it in gear and it was a Saturday and a number of fellows were hanging around the mill, she started to whine up and it looked like I had a peace of Bolgna hanging on there it was flapping like a peace of rubber. Need less to say the saw shed emptyed in a hurry  :D I took it back to my saw doctor and told him the story he hammers it and says Bill if you ever try and hammer a blade again Don't bring back over here. So the story goes I never hammered another  ;D

I've often wondered, as a tool maker, how all that pounding on a steel plate makes it run true. I still don't understand it however I see that it works. I, like many, would like to know more. Autocar... Whats the name of your book?

UPDATE...
Installed new blade and the mill cuts them big ol poplars waaaayyyyyy better but still not perfect. I pulled the carridge off and noticed the track wasnt 100 percent true and also noticed the middle wheels on the carridge was out some.
Another thing I did today was lower the whole track down 1 1/2 inch, now Im making use of the whole blade.
The more I play with this ol thing the more Im starting to understand it better.  should be n full producton n bout ten years or so....lol

I like many other sawsmiths was tought 1 on 1 by another smith and ALOT of phone call's in the months following the training. Since i started about 13 years ago i have accuired 2 Armstorng 3-60 Stretcher rolls (That save alot of Hammering) Numerous straight edges and hammers. I have also learned how to weld new Shoulders on wrecked saw's and enjoy doing it every day. I could not handle setting behind a desk all day.

For a long time tensioning saw was considered a black art,and smiths that did it were very tight lipped, job security.I've been interested in it a long time,it can be a curse as you are like a doctor.My understanding is two things are done,lumps and creases are taken out then tension is put in the middle area of the plate.Think of tension as a slight cupping of the plate and when it spins at hammered speed it straightens out and is stable.Many smiths learned by wrote cause and effect the better smiths understand metal and why they are doing it.Best to use boath stretch rollers and the hammer.Hammer to take out the knots and roller for tension. Please correct me if I'am wrong. Frank C.

SPD748 I P.M. you last night with the name of the books  ;)

not all saw that need hammered need tension put in the middle. some need tension taken out of the middle,some need added or taken out of the eye. As far as using a hammer to take out high spots or bends i prefer using a roller for this over a hammer. As far as sawsmiths beeing tight lipped to Quote a fellow saw doctor "I would much rather compete for hammer work against a compatant hammer man than just a man with a hammer" I've had a few saw's i could'nt fix after having a hammer laid to them by a "man with a hammer"
