air compressor
Got a tool question. I've finally wore out my 33 gal, oilless craftsman air compressor. I'm looking at getting a belt-driven compressor to replace it. Would it make since to keep my old tank and plumb it inline with a new one to increase capacity? Or should I just spend the money on one with a bigger tank to begin with?
Thanks,
Mike

At the end of the day, the compressor will run for the same amount of time, you will still be using the same amount of air. If you plumb in the second tank, the compressor will kick in less often but run for longer. I'd prefer mine to run more often but for shorter periods, this give the pump heads a chance to cool a bit more between runs. Get a reasonable size tank and leave it at that.

Try to grab the biggest one you can afford or have space for. I picked up a used 80gallon with a bad electric motor off of CL sometime back for almost nothing. Spent almost 300$ on a OEM motor and it now runs like a top. But even with 80 gallon tank you can have it cycling quite often when using air tools. I couldn't emagine having a smaller tank to be honest. Probably not neccesary to plum in an extra tank for normal home use but go big if you can, especially if you plan on using a lot of air tools.

Good points. Another thing to consider is the need to ensure there's no condensation collecting in the two tanks. If you drain them manually each day it's maybe not a hard thing to remember, but if you use automatic drains you're adding expense. Stu

I use to have a problem with moisture but didn't realize it until I tried some blasting and kept clogging. I only have one of those blue harborfreight filters at the tank. I ended up buying a moisture separator at Home Depot for 20$ and put that at the tank, then ran 25 feet of air hose around my garage (slightly sloping back to the tank), added my HF filter and then added a Motor Guard filter and my air is now totally dry. I wanted to do a quick setup that was fairly easy and may eventually plum in some pipe but for now this was quick and easy and works just fine. I haven't always been very good about draining but I do drain my tank and filters after use now.

Thanks for the replies guys. The main reason I asked is that most of the compressors I've looked at so far are about $100-$150 apart for the same motor on a 60 vs 27-33 gallon tank.
I got better at draining the air after I started sandblasting. I do use a separate water filter/regulator mounted on the wall. I've had my current compressor for almost 18 years now, but rebuilding this truck has finally taken its toll on it.
