Don't be fooled. What you are about to see is not a TA50, nor does it cost $300+

Normally, I'd say go for quality, get the Rupes. The problem is that it's over $300 and they clearly claim that they do not think the machine will hold up to polishing. I'm not willing to pay $300 to find out that it's going to explode in 6 months.

I've been reluctant to buy this tool for a long time. I heard that you couldn't get backing plates, that it was loud, that it was not a true DA and only orbited like a denibber.

I'm here to tell you that all those rumors are false and I'm not sure where they got started.

Firstly, it is a true DA. It's counter balanced and has a free spinning spindle.

Secondly, you can get backing plates...for like 6 bucks. . .at Harbor Freight.

Thirdly, it's not unbearably loud and to top things off, it has plenty of power. HF recommends 90psi. I cranked my regulator to 100. I figured at $25 (yes $25!) it's worth testing to it's limits.

As you will see in the video, it is also variable speed. I can easily spread the product and then crank it down for correction.

Ignore my nasty, cruddy jeep. It's a fishing, kayaking, go anywhere vehicle.

This is how you remove the backing plate.

This is one of the best looking and what appears to be a well made tool, that I've purchased at Harbor Freight!


As you can see. It works very well. I'm using a foam pad that I cut out of a Lake Country flat pad. It's really too thick. I'm convinced a very firm, slightly thinner foam pad would be the best.

I cut out a meg's mf cutting pad and for some reason it felt very grabby. It worked but was just ok. The opposite is true on larger DA's, where MF tends to spin faster and easier. On the little 2" the foam was nearly impossible to stop spinning. I think the Mf pad was just too heavy.

My next experiment will be a megs Xtra cut disc. I think you could do some insane cutting with one of those on this machine.
 
Can't get my vid to show on here. Copied the link from youtube...any suggestions? Until then, you'll just have to follow the link.
 
I was actually thinking about picking one of these up myself. Nice review.
 
What size air compressor you running that machine on, if you don't mind me asking. Thanks in advance, great video.
 
60 gallon porter cable. I'll get the details a little later when I have more time.
 
Is yours spitting oil all over your palm out the air vent? I didn't oil it out of the box either. Picked it up last week for sanding some gouges out of aluminum.
 
It does spit a little oil. The only real con I have found so far. You can turn the vent to spit a different direction though lol.
 
Mr. Wayne,

Awesome writeup!

This looks like a great solution for black door pillars and the small bends in sheet metal (where you were using in the video) and any where near window trim and such.

So... the BP for the unit didn't come with it?

Yeah, you must have been running a 60 gallon... I didn't hear the compressor kick on one time, lol!

Many, many thanks!

Yeah, it'll probably run a minute and a half or two minutes without kicking on. Even when it does kick on, it catches up.

Dellinger, the BP did come with it. They also sell extras.

We all know that there are tight spots on certain cars that just can't be polished by machine.

I'm not sure this will get absolutely everything on every vehicle, but it sure gets us closer.
 
I would put money on your alls oil problem being a plumbing problem with the air compressor. Most people do not plumb their compressors correctly for heavier use. To do it right, you need multiple water drops and lots of piping to let the air cool. A filter at the compressor or at the end of the hose just isn't enough. Lots of info and different ways of plumbing on painting and body forums. Thanks for the review, this is definitely worth checking out for the price.

Mine's not plumbed correctly because up until now I've just been using it for air purging. I'll be adding filters soon. The reason mine was spitting oil was because I was adding drops of oil directly into the machine and probably put too much.

Good call on the water drops and such. I'm sure it's definitely important for extending the life of air tools.
