Clayton717 Posted June 4, 2014 Report Share Posted June 4, 2014 Went out tonight to continue cutting on the baseball glove intarsia order(25), and my saw kept speeding up and slowing back down. I made a couple small cuts and gave up it just wasn't cutting right. I took the brushes out and they looked pretty worn down I just placed an order for a couple replacement brushes, hopefully that is the problem. If not I will be looking(and saving) to get the excaliber. In the meantime of friend is going to let me borrow his saw (my old dremel), so I can finish cutting out the gloves and atleast keep working on the order. I just replaced the pivot arm (that make the machine work) and bearings in December. They were shot. I'm thinking it's about time for a new saw, time to start saving Quote Link to comment Share on other sites More sharing options...
browders Posted June 5, 2014 Report Share Posted June 5, 2014 I does sound like you've managed to wear out that saw. Just curious, how long have you had it? Clayton717 1 Quote Link to comment Share on other sites More sharing options...
Clayton717 Posted June 5, 2014 Author Report Share Posted June 5, 2014 I bought in December 2011. it gets used almost everyday for a couple hours. most of the use is cutting 3/4" hardwoods for my intarsia. Quote Link to comment Share on other sites More sharing options...
heppnerguy Posted June 5, 2014 Report Share Posted June 5, 2014 I have this problem occasionally with my DeWalt when it is really cold in my shop. Try letting it run for a while. This usually takes care of itself in about two minutes. I have never had it happen except when my shop is really cold..

Clayton717 Posted June 6, 2014 Author Report Share Posted June 6, 2014 If ya ever get it figgered out let us know as mine is doing the same thing but with a knocking sound too. sully As soon as I get the parts in I will let ya know if it worked. Mine was knocking before And I fixed by doing a couple things from here- http://www.scrollsaws.com/SawReviews/DewltTuneUp.htm . A few months later it started banging again but louder, so I tried the same fixes again but didn't work. I tore the saw down further and that's when I found the top bearing on the drive arm was pretty much missing. There is also a link in the above link to buy parts from. . sullyscroller 1 Quote Link to comment Share on other sites More sharing options...
Clayton717 Posted June 13, 2014 Author Report Share Posted June 13, 2014 well I got the new brushes for the saw, put them in and still the same. Didn't work. Looks like it's time to start saving for a new saw. By the time I keep buying replacement parts for ol yeller I could of bought a new saw. I'll baby it until I can get a new one but no major projects for a while. Quote Link to comment Share on other sites More sharing options...

LarryEA Posted June 13, 2014 Report Share Posted June 13, 2014 I gotta tell you that this is not my favorite post to read. I'm sorry for your problems. A prayer they are resolved. I have to purge these problems and thoughts from my mind. It would take me ages to replace my saw. I am sincerely sorry for what you have experienced. God bless and may your problems be solved soon.

Jim Finn Posted June 13, 2014 Report Share Posted June 13, 2014 I bought in December 2011. it gets used almost everyday for a couple hours. most of the use is cutting 3/4" hardwoods for my intarsia. So yours lasted 2 1/2 years. Mine lasted 20 months so you have done well, so far. Quote Link to comment Share on other sites More sharing options...
