Drag Saws

[Jeff]

Nope, its just a sprocket that fits the flywheel shaft size on the engine, with the same tooth profile as that of that big clutch sprocket you see on the saw.  You can still by the chain at tractor supply. I just bought a roll and have it ready. Its a small flat, square link chain.

Could ya have one made ???

[Bro. Noble]

Jeff,

What size of shaft and sprocket do you need?  What is the chain size?  Is it the old cast chain or stamped chain?  We got lots of old junk around here. 

[Jeff]

What I found to go on it, for now, is stamped. Bought it at Tractor supply. I am pretty positive what goes on it should be cast type chain.  The engine shaft is a 1 1/4 keyed. By my estimate I need a drive sprocket about 3 inches in diameter


Theoretically, the engine should run at 550 RPM. the driven sprocket is 50 tooth and about 19 inchs in diameter (18 if you measure from the bottom of the tooth across to the bottom of the opposite tooth), from what info I can find, the saws usually had a working speed of around 90 strokes (revolutions) per minute, so whatever that works out to for engine sprocket size, but I AINT PICKY.

jeff do you have a farm COOP close it looks like an idler sprocket from a feed wagon or such will work
also thats what we use for dust chain on that old mill i had.

[Jeff]

Sorry, I can't help it. I love my dragsaws. :D  Here is a a photo after bolting the saw on for the first time. I dont have a clue how many decades it has been since the saw had its saw. This is the original blade, found with the saw. It was in amazing condition considering the condition of the rest of the machine.



Here is a close up of the clutch sprocket mechanism. THe new Hercules put the clutch on the big driven sprocket rather then the small sprocket on the engine. I think this is a poor idea as the big sprocket and its drive chain will turn when ever the engine is running. Not as safe as thier first design.




Here is a photo of the blade guide, stand. slide portion of the saw.

Jeff,
Excellent job refurbishing your drag saw.

[Tom]

If that Red and Green, going-back-and-forward thingy was my arm, it wouldn't take long before I was bear caught.

[sprucebunny]

That's great, Jeff  8)

I love the noise.... ;D ......puckeda-puckeda-whack .... :D

[Jeff]

Just wait til you hear it in person. It sounds great. It really sounds different then the video though.

[Mike_P.]

Jeff:

Congratulations! It looks great.  Now you're ready to go to shows.

Mike

[Jeff]

Mike, thank you for Rust Reaper! There were several very important parts to the saw that were seized that I dont know how I would have gotten apart undamaged if it had not been for "The REAPER".

[beenthere]

That looks great Jeff. Anxious to see it run in a 'live' demo in a couple weeks. 

My wife just doesn't understand me re-running that video over and over.   :
I could mention something about her quilting hobby, but don't. 

We'll be coming across on the ferry from Manitowoc to Ludington. That should be more relaxing than driving around the south end of Lake Michigan.
