Operating a 90’s Norwood mill - issues with track &/or carriage wheels?

Good afternoon,

This is my first post here so i'll start by saying that Im from the Pittsburgh, PA area and last year started operating my Dad's Norwood mill that he bought I belive in the mid to late 90's. He has been unable to run it for several years due to a work injury, but up prior to his injury my Dad and brothers would run this often.

After sitting for 7+ years it took some work to get it going again, and ended up having to put a new engine in it (13HP honda). I ran it last summer almost every weekend, and recently got several loads of trees that i want begin cutting withint the next week or two. Im having issues however that it is not smooth rolling on the track like i remember it being originally. It looks like the wheels may be worn down and may be binding on the angle iron track, but im not certain exactly what they looked like when new. Is this somthign that can happen on this style mill? I've spent time making sure the bed was level and square and it was all perfectly aligned. 

if the track or wheels needs replaced, is it best to replace with the same parts, or has anyone upgraded to anythign else? Any suggestions or input would be welcomed.

Below is a link to a photo of the mill just to show it, Im not certain what model it is.

I've used and abused mine, and sometimes it gets so it isn't running smoothly.

Here's a couple tips that may help.

  • Don't use your eyes, but run your hands down the top edge of the track, and the rail where the rollers ride. See if you feel something that isn't visually apparent. 
  • Load a weight on the saw (stack of boards, anything), and run the saw down with the engine off and the band just above the top of the stack. Stop anywhere that seems odd, or that grabs, and look where all the wheels are. Any protruding bolt, anything?
  • Use a string and two nuts to check for level. Fasten a string to one end, run it over a nut (to clear the rail by the height of a nut), down to the other end, over another nut, then tighten it. Light line like strong fishing line may be best; something with minimal sag.
  • Do the string/nuts trick on the bunks.
  • Check the blade guides; do they support the blade pretty well, and fairly even on both sides? I had one of my blade guides get bent by a log, and I didn't notice; couldn't keep the blade from wandering. Fixed the guide, it cut straight again.

 

Hope this helps.

Crud can build up on the rails and rollers (sap, wood residue) and make for bumpy rolling, especially in winter.  The rollers have bearings which can be replaced inexpensively.  Pry up one side of the carriage and check to see if they roll freely.

What Eddie said and spray some oil or wd40 on and around the wheels to soften and get rid of any crud build up.

Thank you all for the responses.

I will be at my parents Friday and will check the suggestions above that I haven’t already done.

Just curious, does anyone know what model this mill is?

Looks like A Mark 4 Mill. JR has one just like it.His has the 20HP Honda motor and runs good.

Hello Agaeris

 

First off, Welcome to the forum

 

From the picture you posted, seeing the bungees holding the front guard covers on lead me to believe that you have a Mark 3 or Mark 4 sawmill. The LumberMate 2000 had a metel clasp and keeper for guard latch covers. It's quite possible that your carriage wheels have worn down. We can help you out with that if that is in fact the issue. Feel free to give us a call at 1-800-567-0404. If your father was the original owner there's a good chance we'll have his mill on file and will be able to identify exactly what model you have.
