Does anyone have any success with electric dual action sanders?

I'm looking to do get a sander and an air compressor, but due to my low budget it seems that a pneumatic sander wouldn't get enough air from a smaller air Compressor. 

 

I have a ryobi 150mm one and fark me it's done some work. My recomendation would be just try and buy a 150mm one as the discs are more common and cheaper.

Cheers @rusty360and @JustHarry I might have to just stump up the extra cash for a better compressor cos it seems the one I wanted (40l 2.5) doesn't have enough free air delivery for my spray gun anyway despite what the sellers may try and say..and just get the air DA.. 

 

Hey mate, I'm no expert but have used both and to be honest the electric was much nicer to use. Quieter, no air line to drag around, no hamming the shit out ya poor wee compressor as they chew plenty of air.

Yeah i've gone away from air for most of my stuff, so I have a $1500 compressor to blow up tyres / balloons... Electric would be my pic too for big jobs. I tend to do smaller ones so roll a 125mm battery sander and a few batteries. Ain't no pristine paint jobs leaving my shed though. Air is good, especially if you have a big shop. But it's pretty noisy and a decent compressor is $$$ so you'd have to be pretty into it for that to pay off IMO.

I've got my compressor and water trap, and an air line with crimped fittings on it. However to fit the water trap I've got to make a hose connecting from compressor to water trap then from that a hose to my gun.

Is it okay if I just cut some hose off and use barbs with hose clamps, or should I just get another air line with the crimped fittings? 

Cheers

Oh and I got a ryobi one+ sander!

Barbs and hose clamps will work fine.

You really should have some line between the compressor and water trap to let the air cool down and the water condense.

Water trap at compressor is wrong. Do some homework on that. Pretty sure it's pointless in that location. As mentioned above, cooling is needed. 

There should be plenty of guides online as to how to set it all up for best results.

I have a water/oil trap at the compressor, then a disposable filter at the gun after about 15m of hose and it has worked fine for the painting I have done. 

Better to have a condenser or a line of pipe going up and down the wall for everything to cool and drop out of the air. 

 

But I move mine around a lot, and the gun filters seem to last forever (I cut the last few open to see how they are doing) and I have never got a fish eye or water droplet come through the gun

 

One day I will mount it outside the shed so it's not so noisy and run some air lines through the wall

just on the crimped fitting hoses. Honestly i've had such a shit run from these over the years. They often leak after a while. I much prefer to buy the hosetails, and oetiker clips and just make my own as the premade length are always too long or short or wahtever.  buy a roll and make your own, ( you dont need the fancy pliers for those clips either ( can just use blunt sidecutters or vice if you must ) but they make a nicer job.

( maybe just always bought the cheap shit? ) dunno but i avoid them now. air leaks are one of my pet hates in a workshop.

 

I had to cut the crimped ends off a new hose from BNT and use normal tails due to the leaks.

Where do you get those clips?

I'd use paint stripper. The stuff from super cheap that has dichloromethane in the ingredients is safe for aluminium. Stinks terribly, I think it has ammonia in it. Works great for removing carbon from pistons and valves and stuff without scratching too. Don't get it on your skin, even a tiny little bit will start to burn in a few seconds.

Repco brand paint stripper seems alloy safe.

 

It's so shit it takes 2 or 3 applications to get paint to bubble and doesn't seem to touch alloy.

It does make skin wrinkle up weird, but not bad enough I'd bother with gloves though

When I was first using paint stripper I didn't let it dry enough and then hit it with a wire wheel with no face protection. Sprayed my whole mug, it started to sting, realised the error of my ways and sprinted inside to the shower just in time
