It's true |
|
I have found the advertising for the PC Low Profile sander to be true. As a finish carpenter, I spend a lot of time sanding. So any product that will shorten that time is welcome. The sander with 120 and high speed cleans Pine and Maple as fast as you can move the sander. Scratches or dents, just a little longer. Put 80 on and slow it down a little and it removes wood quickly. The top of the sander is larger than other sanders, so adjust how you normally grip. The hard dust collector is a second hand hold for me. I've used Dewalt, Bosch, and Makita. Currently, using a Dewalt for 80 grit so I don't have to change discs, but I still go for the PC with 120 95% of the time. Only suggestion to Porter Cable would be to get rid of the stiff power cord for a more flexible one. It may cost more, but it works. |

Porter-Cable hits it out of the park! |
I have used over six Porter-Cable random orbit sanders and always have at least four on hand for use on my Marquetry work. I have found that the P-C's had the least vibration (though still more than I wanted) and the smallest orbit pattern. However, they do wear out after about two years of heavy use. Now, Porter-Cable comes out with the 390K which is almost twice as expensive, but claims to be extremely low on vibration, and doesn't bog down when heavy pressure is applied (this, a no-no, as it causes premature wear.) The "experts" say heavy pressure does not mean more stock removal, but I have found this to be inaccurate. Heavy pressure, at least with the Porter-Cables in the past, does remove more stock, but leaves pronounced swirl marks that have to be eliminated through progressivly finer grits, reducing pressure as the grit size becomes finer. Because I keep several sanders at ready with different grit sizes, this is not an issue to me, as I find the resultant time spent is still less over-all, than if I tried to do the initial stages with "light" pressure.
I purchased the 390K to see if the claims were even somewhat close to believable. To my great delight, the claims of smooth operation and excellent stock removal are not only true, but I believe have been understated! I have used it daily for over two months and it continues to perform flawlessly. The vibration level truly is the lowest of any Orbital I have ever used and the stock removal is fantastic. The resultant swirl marks are also less intense in the coarser grades of paper. Only 'cons' I have are 1) the price (though certainly worth it), and 2) the fact it comes with the 8-hole h&l pad. I prefer 5-hole because you get a little more surface area of grit on the work piece, and I use a vacuum dust exhaust so the extra holes are meaningless to me. I obviously don't know how long this new model will last compared to my other P-C's, but I suspect it will be longer. Even so, the additional cost over the earlier models is money well spent. |

Good Vibes but not easy on the hand/lungs |
I have used this sander for several projects and on the good side it does a great job of sanding. Also I like the fact that there is not a lot of vibration and the thing has a good brake and stops when you shut it off rather than walking all over the bench while it slows down. On the other hand...you really need a HUGE hand to comfortably use this thing for more than a half hour or so and, if you do not connect the sander to a vacuum system or have a downdraft table you will have dust all over the place.
I would not recommend this tool unless you find one to hold in your hand and determine if it is comfortable first. |

Best sander ever used |
|
I bought this sander based on a review I read in a wood working magazine That i subscribe to . I have had several other sanders ,Porter Cable , Ridge , Makita, and this is by far the best I have ever use. I read a few reviews that said it was to big and bulky to grip , but I don't fell that is an issue at all. The best part is very little dust goes out into the air . I have mine hooked to a craftsman sander vac . It also collects great with it's own dust collection . I have always like Porter Cable products but this is one of their best. One con a little pricey . I did a lot of research and everybody is charging the same . Porter Cable must be controlling the price . If money is not an issue , buy this sander . |
