Ist of all get the Palm sander, you don't want that big old boat!

You can buy a velcro replacement pad and some companies make a vlecro sheet, that sticks to your stick-it pad so you can use velcro. I buy the pads but buy the sheets to cut and fit my had blocks. I know Sia make the sheets.

That is a very pricey sander. I have been using a Chicago Puenmatic for about 10 years without any problems. it cost me $30.00 through harbor frieght tools. when you buy any tool consider how much you use it and buy accordingly. If you use the tool daily then quality name brand maybe best. if occasionally then less expensive is a better way to go.

The big thing with DA sanders (as well as other air tools) is the amount of CFM they use. The more expensive ones have closer tolerances and use a little less air (CFM). but that does not mean they always are better.

How big is your air compressor, what is the CFM of it at 90 PSI? THe goal is to have a compressor that produces more CFM than the air tool uses. THis will mean that your compressor will run less to keep up with the tool which in turn saves on your air compressor.

I suggest that you spend the money on a bigger air compressor with a bigger tank and less on the tools.
As far as the pad goes. DA sanders come with a pad that is for sticky back sand paper. they tend to be either 5 or 6 inch.

Hope this helps

My air compressor is a Ingersoll-Rand (35 gallons I think) it cost me a pretty penny...
I think it's 7.5CFM at 90PSI if I recall correctly.
I will be using the sander probably 4-5 times a week. I'd rather buy something that is a little spendy, but I know it will last a long time. Rather than a HF 50 buck sander that I will have to replace a few times...


Barryk,
What Palm sander is the good one? Is this one good?
http://www.aaabrasives.com/shoponline.asp?point=moreinfo&catid=326&id=4507&pRange=0&iCurrentPage=6

Thanks for the help!!

I looked all over the web sight for that palm sanders CFM rating and can't find what it is.
I have a 7 hp comressor with a 60 gallon tank and it delivers 11 Cfm at 90 psi. sometimes that is hard to keep up with my sanding tools. CFM is very important, I would suggest you write to the manufacturer and find out what it is before you buy.
I think your compressor may be small for your average sander, even good quality ones.
I am impressed with you asking questions up front, most of us have learned the hard way because we are to proud to ask.

The only thing that is going to be a bummer is if my compressor is too small. I wouldn't mind going to a big one (60 gallon is the largest I can find locally) but here is the story...
Oringially I had to get a "portable" air compressor with wheels because where I work is outside 100-200 feet away from where I store the compressor over night.So one of those floor mounted compressors (The one I saw was 60gallon) wouldn't have worked................BUT now next fall I am moving into a smaller house, WITH a garage that I could permantly mount a compressor in.
The problem is money is always tight, and it will be hard to convince my mom we need another air compressor (having one with wheels is always going to be handy for me, personally) and also I could have gotten one for 1000 dollars-60 gallons-floor mounted (but it was cambell hausfeild) but I got the wheeled 35 gallon-800 dollar compressor instead.
I will write an e-mail (if they have one) or write a letter to the manufacturer to find out what the maximum and minimum CFM I need for that palm sander.
I guess I should search first, but from your opinion, what is a top quality big air compressor that will last me a long time... but not cost me a house morgage?
As always, Thanks for the help!!

I'm pretty sure these are the same...
http://www.aaabrasives.com/shoponline.asp?point=moreinfo&catid=326&id=4507&pRange=0&iCurrentPage=6

http://www.dynabrade.com/cgi-bin/Industrial/56011?45ktA8u2;;50

but on the Dynabrade website, it says that air sander is discontinued. I would guess AA Abrasives still has some to sell. On the dynabrade website it says:

English: 2 CFM @ 90 psig
If that is all it needs, would my compresso r hold up?
Thanks for the help!

Or it could be this one, this one is just a different colour... it says 2CFM at 90PSI too...

http://www.dynabrade.com/cgi-bin/Auto/10326?45ktA8u2;;93

I thought it said they were DA sanders, but are the ones I listed above dual action, or are they not?
This one says it is...

hi, trust me its not the 2cfm rating. its the rating just above it. it says 16scfm. thats more like it. i have 2 of these and they definately use around 16cfm. all the dynabrade palm type orbitals gnerally have the same motor so they all chew up the same amount of air they just put different pads on them, change the orbit size or add a vacuum feature. if you goto another brand you may find one that uses less but i dont think you will find any in your range. any tool that runs constantly will chew up the air.

So you guys don't think my air compressor will beable to run the dynabrade D/A sanders right? Since they require a lot of CFM. Can someone point me to the direction of an air compressor that will do fine for it? links are good.
Thanks!!

Also, if there is an increased CFM between compressors, will that affect using a spray gun? or can I adjust the CFM? Sorry for the dumb question.

most air sanders use somewhere around 15cfm. if you found a compressor that will supply you with atleast 17 cfm you should be ok. forget the horsepower rating. these days it means nothing. the cfm is all you need to worry about. most will be rated at 90 psi. the cfm is the max amount of air the compressor will supply, if you have a tool that uses less air then your good. a tool will only take the amount of air it needs. if your going to dish out the cash for a compressor buy something thats industrial duty. ingersoll rand is a good one but they do have diffferent quality air compressors. you'll find the cheaper ones at home depot or lowes. while some of these are good, you'll get something more heavy duty from someplace that specializes in compressors. www.eatoncompressor.com makes nice compressors too.

I already have a air compressor, I mentioned it was 35 gallons or so. It doesn't have near the ammount of CFM I need though.
So something like this would be good?
http://www.eatoncompressor.com/catalog/item/504747/172993.htm
it has 24 CFM of displacemtn, and 17.5 CFM of free air at 100PSI
I want a fairly big one, 60+ gallons...up-right to save space

I like this one, but thats probably too big for what I need?
http://www.eatoncompressor.com/catalog/item/504747/172473.htm
21.5 CFM displacement and 17 CFM free air @ 175 PSI

QUESTION: The first one is measured at 100PSI and the 2nd one is measured at 175PSI... if they were both measured at 90PSI... would the CFM rating be larger?

You will never wake up in the middle of the night screaming, "I bought too big of a compressor!". The opposite might happen. Buying a compressor is the best time to streach the budget a bit. You can buy a $30 air sander and your big compressor will run it. It will just shake a bit more than an expensive sander or wear out quicker. You could spend a bunch on the sander and watch it sit on the shelf because your compressor won't run it.
Remember, the compressor is the basis almost all your body tools need to run.
I bought a used 2 stage just slightly bigger than the second Eaton and I've never once regretted the decission.

both will work for you however if you can afford to go bigger by all means go bigger. the compressor will probably last you most of your life so you never want to be limited down the road. 175 psi is a two stage compressor. it doesn't necessarily mean that the cfm is higher it just means the reserve capacity is higher. it basically stores more air in the tank.

air sander

Hi.
Generally speaking you need 18-20 cfm at 100 psi, you will never run anything higher than 100 psi except for maybe an impact wrench which doesn't run continuously like an air sander. You need to deliver that cfm at a relatively low pressure, so the pump needs to be able to keep up once the tanks runs down.
Dynabrade makes good tools, also check out Hutchins http://www.hutchinsmfg.com/ I use Hutchins which are made in USA and can really take a beating, not too expensive either.

Good luck,
John

Hey,
Okay, what are some other brands of air compressors equal to eaton in quality? Someone suggested ingersoll-rand... is there any more? The only problem is eaton is in ohio, which isn't exactly close to close to me. BUT if I think that is my best bet, I will take my uncles truck down there and pick it up. I just want to get best quality that will last most, or all of my life!
Thanks for the help
