How smooth does your PC run?

**rcurley55** · 04-29-2005, 04:30 PM

I`ve always wondered something about my PC. It is not a quiet or smooth running machine - not like other orbital sanders I have.

It really is kinda loud, and after working with it for a few minutes, my hand damn near falls asleep.

Is everyone else`s the same? Or is mine a dud?

I do have the 6" weight installed, but it felt exactly the same with the 5" in there too.

I currently own a cyclo and a milwaukee rotary polisher. Both of them are load, and vibrate quite a bit. I also used a PC, and it was basically the same. Anytime you have a machine with that much power, and that many moving parts, it is going to make some noise and vibrate some. I doubt there is a problem with your machine, if that is what your worried about.

I just wanted to make sure it`s not supposed to move as smooth as let`s say an orbital palm sander - something of that nature....

thanks for the feedback

When I turn mine up to 6 it sound/feels like it is going to fall apart

rcurley55- It sounds normal to me. Many people are a bit surprised at how, uhm, less than user-friendly the PC can be, especially on speed 6. You might want to look into vibration-reducing work gloves.

brwill2005- Maybe it`s just me, but I find the Cyclo to be a *lot* nicer vibration-wise than the PC. That Milwaukee is another matter though, I used one at work back in the day and it was a bit of a monster (but then I was a kid at the time too).

ok guys...thanks - it does sound normal to me as well!

Mine`s loud and vibrating (esp. at higher speeds.). My rotary is also loud. I think a nice "bonus" for these machines would be some hearing protection.

The only complaint i have with the PC is where the speed dial is located. The dude that put it there should be put in a nut house.

mine runs fairly smooth, kind of a sewing machine sound. I fine tuned it with some washers (additional weight) and the 6" counterbalance. The vibrations are not so bad, but still there slightly.

I found using the handle does seem to increase the perceived vibrations

I agree with this, the selector should be near to the On/Off switch, controllable by thumb. Silly position where it is .... I have noticed that when I switch my PC off, there is a whine as the motor comes to a stand still. Not sure how long this unit will last me

The vibration of the Cyclo is much less than a PC and seems quite comfortable to work with. Vibration with a PC is normal I fear.

Witha a 6 inch counter weight, 5 inch backing plate 6 - 6 1/2 inch pads and removing the handle and holding the machine by the head I can crank mine to 6 with no discomfort at all. Runs very smooth.

I would say the same, although mine has a 5" c/weight, no problems at all.

Yesterday, I applied AIO to my car with a 4" SFX Blue finishing spot pad with 3 1/2" backing plate (PC with 5" weight) - so easy to use which made the polishing stage a pleasure.

Only discomfort I have is when using the Orange cutting/restore pad, makes the PC bounce around a bit.

Mine has always been very smooth -- I purchased it from Meguiar`s and have been using their pads, and a 3M backing plate the same size as the Meg`s one, so I`ve been happy with it.
