Chain Speed Calculator

...because I got bored. It's nothing fancy. It's a plug & chug application -- I didn't spend a ton of time making it look pretty.

FEEDBACK IS WELCOME.

It should automatically recalculate and update as you change the numbers in the input fields.

Bobby it looks great and works great. Chain speed does matter. One thing that keeps coming up is the difference between saws and what they can pull well. A really fast chain speed goes through softer wood well , but as soon as it starts to go through hard woods with larger diameter it almost stops. Then the faster chains seem to get chewed up very fast with tougher cuts. Thanks

Calculator works, but You need to add one more field. I believe chain speed is measured in inches per minute, IPM. Manufacturers do advertise ft per sec.
Formula, Take the chain pitch and multiply by 2. Multiply the above number by the number of teeth of the saw sprocket.
Multiply that number by the saw R.P.M.
The final answer will be the chain speed in inches per minute, just divide by 12 to convert to feet per minute.

At any rate, for folks interested in building a hydraulic chainsaw, this type calculator is very helpful when trying to decide how big a hyd motor to use. Sprockets can be bought in various tooth counts over what is available for a gas chainsaw. You can play around with different size hyd motors and oil flow and sprocket size to get a chain speed similar to your favorite gas powered chainsaw and know you will have a hyd saw that will work. Saves a bunch of trial and error and possibly money when it comes time to buy parts.

OK working for me now.....wouldn't change before...probably the problem on my end. Added it to "Favorites" Slick!!!

Inches per Minute -- Got it. Give it a whirl.

What about centimeters per minute and kilometers per hour for us canadians. Lol.

On my older huskys we plug the govenor off on the carb, go up one tooth on the driver sprocket, never worried about much else and raced’em at the fairs. Huskys kicked butt.

Doesn’t work?

I was adding stuff for our Canadian friends and broke it while doing so. Try it now.

I put the info in still no work.
