Chicago rotary Review

New Normal
Just got a new Chicago rotary in the mail the other day. Yesterday was the first chance that I had to give it a go.

Packaging and labels

It arrived in a nice box that protected what is inside very well. Thru shipping it was indeed intact with all the assorted items needed to get started. Wrench, backing plate, and a soft white foam pad.

It did not have much for instructions. It seemed pretty much self explanetory to me. The whole machine is rather simple. Very light in weight. Mostly plastic on the outside. The cord coming out of the machine had a decent thicker covering to allow some movement without fear of cracking or pulling out. The operating range for the rotary is 300 to 3000 RPM's. It has a thumb control on the handle marked with number's 1 trhu 5. Each number is progressively higher but not variable speed.

It does have a detent switch to lock it when changeing backing plates. Made for simple installation of same. I did not use the original backing plate. I had purchased a flexible backing plate prior to purchase of the Chicago rotary. It has a d-ring that I installed with Allen screws and Allen wrench that were provided.

I have a wide assortment of pads to use with the machine. Yet on the vehicle I worked on I did not need many pads. It is a good thing that the vehicle did not need major corrections because this is not the machine to get the job done.

Although it was light and easy to handle the machine could not take any pressure at all on the paint surface of the car. I had very little holgraming while it was in use. But I believe the reason for that is because it hasn't any power with which to get you in trouble. In truth, that may not be a bad thing for a beginning rotary user.

I had some minor marring from a previous detail on the hood of a Ford Focus. Used some FPll and a yellow pad from Auto geek to effect the defects. It did do the job on this area. I know that my PC with the same pad and product could have done the job as well. Most likely faster, because the Chicago rotary is very underpowered.

It did do one thing that my PC was not able to do. That was to affect change on my bumper with water spots. Using a LC 7.5 in. polishing pad and SSR3 on the chrome portion of the bumper I was able to polish out all of the water spots that had plagued me these last few months. I was able to build up some heat to get the changes that I was looking for, with this rotary. Something that I could not adequately get done with my PC.

Recommendations....

I guess that I would have to say that the machine acted in less than a stellar way. Of course every one had mentioned that very fact in every thread that I have ever read about the rotary. Yet, for $32 including shipping, it was worth the experience. Bottom line I cannot recommend buying one.

Am I happy that I have a Chicago Rotary....Yes, I am. It is just another tool to use in the battle for the Ultimate Shine. It was light and easy to handle. It did effect change as I had hoped(albeit painfullly slow). It is also for the person that has a budget to adhere too. The work can get done but not on a production basis. For $32 is a small price to pay for rotary heat build up that is sometimes necessary to make a correction but not so much as to burn the paint.

nice little writeup! What is the rpm range on this machine, and what were you running it at rmp wise?

Thank you for pointing out that little faux pax. I have added that information.

I never got the speed past the two mark. I would guess that to be about a 1000 RPM's. Did not need speed in my case just perserverance to allow the machine and the product to work together.
 
cwcad- I aslo have a CE Rotary and like you said it is a good learning machine. There are I think 3 models and the one i have has a trigger control and a speed dial. It takes a while before the machine is up to speed but once it is there it isnt bad. I usually use it on Speed 4 with a hologram here and there and not too much heat. I tried to burn a spot on my spare hood but I couldn't, which makes sense now that you mentioned the power or lack there of. Its a decent machine, corrects defects and you can't beat the price. Once I gain enoughexperience and have some extra cash hanging around I'll probably upgrade and see the differences between two different rotaries. Good review cwcad.
 
Nice write up, I love mine. I tend to use at around speed #4, should be about 2000 rpm. Every number is about 500 rpm. I'll agree that you need to crank it up a bit to get the really tuff imperfections out, but i've had no trouble at all. I use only poorboy's SSR's and pads from Classic Motoring Accessories and have had no trouble. I always follow with a PC to remove any hologramming that I caused.
 
Mine must be a different model...its RPM range is 1,000 to 3000, and it definately DOES have the power to burn through paint. I got it last year when Harbor Freight was having one of their sales ~$30 incl shipping.

It could be. Sorry...I should of posted the Model number of my Chicago rotary. #92623

Yours has a single handle to help guide. Mine has a D-ring. Yours has a hand guard by the trigger mine does not. Yours is all one color. Mine is orange motor covering and black pistol grip. But they are both Chicago Electric rotaries. :yes:
 
I've got one myself, and for the price, it's a pretty good machine. It's heavy, but it seems to be pretty durable, as I've thrown it around quite a bit and it still works fine. Used it to get 2000 grit wetsanding marks off my entire car, did a stellar job. If you have a PC, and want to experiment with a rotary, you might be better off with this one rather than spending all the money on the dewalt only to find out you don't really need one.
 
I finally tried out the one I got the other day. The car I was working on is known to have real hard clear.

I first tried some IP with the PC and a orange excel detail pad, nothing

Then the rotary with a foam polishing pad/IP at speed 2, nothing

Rotary w/ megs foam waffle compounding pad/IP and speed 3, nothing.

Rotary w/ megs foam waffle compounding pad/Megs #4 heavy cut speed 3, nothing.

I felt the surface after the last step and it was only slightly warm. I gave up and did not remove the swirls there.

Should I have increased the speed even more? I was afraid to go any higher with the speed.
 
I usually have mine run around speed 4-4.5 and I can get results... I'm not sure why the swirls didn't come out, they may be too deep to get out with any machine, pad or polish. I would bump it up and try again, if you feel that it is necessary.
 
I am with the other respondent about not knowing why it did not come out. Have had particularly good luck with the Propel orange pad at setting #5 to 5.5 on the PC.

I also have had good luck with the rotary using the same pad. I would not be afarid of moving up the speed on the chicago rotary if you go slow and keep it moving. Checking your progreess often to see how it looks. Although setting four would be as high as I would go as I am a relative new comer to the Chicago rotary.

Have no experience in the Meg's pad.
 
Thanks for your responses guys!

The car is not mine, hopefully the next time I detail it later in the year I will know what I'm doing w/ the rotary.

The funny thing is that I was able to create micromarring on the hood of my wifes dk red BMW when I used it with the PC,waffle pad and Megs #4. I was reducing some water spots at the time.
