Bob write in about problems he is having with a brand new Dewalt DWS780 sliding miter saw, and is wondering if anyone here has experienced the same.
Just read your review after bringing home a DWS780. I like the saw, but the slide bearings are very rough – to the point that starting a cut from full extension is difficult. I’ve seen similar comments in other reviews. Lube and bushing adjustment makes no difference on this one. It’s slides smoothly until you pull the blade down, and then the added pressure just overwhelms the bearings, or so it seems. I see that you didn’t have a problem with the saw you reviewed. Did you do anything special to smooth it out, or was it just the luck of the draw? Have you heard of this issue from anyone since the review?
I tested the DWS780 ($599 via Amazon) and reviewed it here and over at Make, and used it a little bit after that. I did not experience any issues with the DWS780’s guide rail bearings, although over time I did notice the bearings weren’t as perfectly smooth compared to other brands’ sliding miter saws.
To be fair, I didn’t make many full-width cuts. The DWS780 is capable of cutting boards up to 16-inch wide, but I didn’t come close to using its maximum cutting capacity. The test sample has since been donated to a non-profit organization, so I lack the ability to try to replicate the issue.
This isn’t the first time a reader complained about the DWS780’s sliding rail, and I have read complaints elsewhere as well.
We’re still waiting to hear back from Dewalt as to whether Bob has possibly run into an isolated defect, or if the DWS780 could be adjusted so that the guide rails and bearings interact more smoothly.
In the meantime, if you have used the DWS780 or another Dewalt sliding miter saw, please chime in with your experience. Is your Dewalt saw’s sliding rail smooth or rough?
