Is this Normal? Makita 9227c question...

asharma · 09-09-09, 03:27

My Makita 9227c just arrived...I'm waiting for my backing plates to arrive in another order...I noticed with the stock 7" wool bonnet when i fire the machine up on lower speeds (say speeds 1-4), there is quite a wobble...? The bonnet appears to be centered...I'm not holding it against a surface when i am doing this...Is this wobble normal for this machine with the 7" wool bonnet? It is my first rotary, so i am not sure if this is normal...thanks in advance...

I'm glad you all ready ordered the new backing plates. Not to put to fine a point on this, the backing plate that comes with the makita is crap, but that's ok, cause so are the pads. (I'm overstating this a bit for fun! So, if your panties are getting wadded up just take a deep breath.)

You might be able to get some of the wobble out by trying again to center the pad but I've never had much luck with those backing plates or the pads, and, I think that machine is one of the best and I've owned at least a dozen different polishers and at least 6 Makitas 9227s and the same number of BO6040s.

I teach detailing so I tend to give away a used machine to a student I think will use it well. That's why I've owned so many.

thanks Robert...so r u suggesting the wobble is normal for that backing plate/wool pad on the speeds mentioned sir?

Not normal, you should have no wobble when machine is turning and it's not touching anything. Take it back. You can try removing backing plate all together and just try running the machine w/o any attachment period to make sure it's not a backing plate off center, but still there should be no wobble ever unless your are touching the surface of paint with a foam pad.

Not right, it shouldn't, but I've never found one that didn't. You can take it back but it's a bad design backing plate anyway. You should get two of the yellow after market pads, a smaller one for use with the smaller foam pads and a full sized one for use with standard full size wool - though, I'd suggest never using the twisted wool pads on anything but a first cut after sanding, stay with the knitted wool, it's easier on the paint and leaves less swirl.

Put that backing plate on a flat surface and see if it's even flat. If it is, you've probably got the only one in captivity.

I have never found one that wobbled when operating in the "air". It's the machine I own and have used on all my details that require buffing. Only certain types of friction cause wobble, and definitely not under no load, nuff said.

I've got a stack of em here and not one is good enough to throw for a dog, but I'm glad to hear somebody got a good one, lol.

Get a self centering pad and BP system. It saves a ton of headaches and a lot of otherwise wasted time. The Edge system is a perfect example. Buff-n-shine and it's many relabeled counterparts is another perfect example. Using the "old school" methods is just outdated and not vert effecient.

So eventhough they are junk someone kept buying these machines anyway so they can have a stack of garbage machines? Really?

asharma · 09-09-09, 05:26

thanks guys...i think the bigger issue is the frikin wool pad is hard to get centered....i got it centered better and reduced the wobble but not perfect...in fact when i look at the velcro backing on the wool pad, the velcro backing is not even centered within the wool pad, and thus would throw the weight of the pad off...when i run it with just the backing plate on speed 1, there is a tiny worble in the backing plate, so i think it is a combination of the pad and the plate...UPDATE:just stuck my LC 6.5 pad to the 7" backing plate and still a wobble at speed 1 and 2...Perhaps a bad backing plate also...only way i will beable to tell is to wait for my new backing plates to arrive...

The machines are good, the backing plates and pads they ship with it aren't as good as the ones from, just for one example, Lake Country. I guess I should type slower.

Mine also came with the two wool pads.

What should I be using these pads for? Heavy cutting? How do they stack up against LC PFW?
