Been using my shaft and butt saw for sometime and was wondering when to sharpen the blade and the bearings in the saw blade spindle. Saw a slight chip on one blade and have to keep cleaning the teeth from time to time because of oily wood buildup but a toothbrush and some lacquer thinner works pretty. Havent sharpened the thing in years. Same with the shaft machine. Getting kind of a higher pitch noise while they run so Im thinking the bearings might be going. Also I notice that Im getting a little bit of a bump in the shaft in the first six inches or so. Havent a clue on that. The edge that follow the roller bearing is true and smooth so I dont know where thats coming from. Thought it might be a slight divit in the lead screw but its always worked well before. Just a slight thickening in about a half inch area where they used to be smooth. Ideas or comments appreciate. Thanks

Mark,

If the first part of the shaft is bumping I would check the head stock play.

I had a similar situation and replaced the dead center shaft and bearings. The bearing id should be a very tight fit to prevent any play. I have my machinist do this job and he gets a body fit.

I am sure you are using sealed bearings but there Are bearings you can buy for 10.00 and some that cost 40.00. I replaced the live center and dead center shafts on both my machines and up graded all of my bearing to premium ones and the results were amazing. If you can see even the slightest run out anywhere the system is not going to produce a good shaft. Anything you can do to make your shaft standards better by even 1/2 of one percent is worth the effort.

I resharpen my blades twice a year but rotate them to hogging dowels before sharpening so all my blanks being cut from .910 to .855 are done with very sharp carbide.

Thanks, Ill try that. Think the whole thing needs a tune up. Things wear out you know and sometimes get out of whack.
