My familiarity with manufacturing hardwood furniture has taught me that about half the time involved in setting up each chair, desk or cupboard is taken up with sanding. If you find yourself attempting to make a livelihood in the woodworking business with workers who're on the clock, you need to lower inefficiency to a naked minimum. This doesn't imply changing into a tyrant but, ideally, eradicating any and all impediments which may be slowing down building, sanding and finishing.
I began my woodworking career with 1 / 4-sheet electrical sander, shortly graduated to an orbital electrical disc sander and finally realized that I might considerably cut sanding time with an air palm sander. I settled on a 5? Dynabrade sander and Sears 3HP air compressor. It took me less than an hour to realize my blunder: The tiny compressor I bought couldn't begin to maintain up with the air requirements of the air sander. It might run out of air strain almost immediately and the air sander would slow down to the purpose of being nugatory. I'd then have to wait for a number of minutes for the strain to construct up once more to get one other minute of sanding.
Compounding the issue was the fact that I had three folks employed as sanders and so I would wish to keep three air sanders working at 10,000 RPM all day lengthy. I did some arithmetic and found that I would want a ten horsepower air compressor with a large tank to maintain up with the demand. I used to be fortunate enough to find a used one with an affordable price tag nevertheless it required three-section power and many it. I had to contemplate the extra expense of an electrician to wire it up to the building's 208 volt 3-phase energy. The massive air compressor was so noisy it might be heard all around the building and down the block however it ran these three sanders constantly. The good news is that it paid for itself in production effectivity very quickly.
Air sanders are aggressive and environment friendly. They're mild in weight when in comparison with their lesser electrical cousins. My sanders took to them immediately and production took off. I used to be as ecstatic as they were. Soon there was one other machine apart from the air compressor which required having large amounts of air within the store: An Onsrud inverted pin router. It was also nice to be able to take away sawdust from benches and machines whereas cleansing up the store at the end of the day. The compressor was additionally used to spray finishes on the completed furniture.
Years later, I built a smaller woodworking shop in my residence which only required one air sander runing at a time. For that store, I purchased a 5 HP air compressor and isolated it in a soundproof room in a single part of the shop. I ran 3/4? galvanized pipe beneath the shop ground to 3 regulators at three different connection places. The machine I bought for that shop was a 5 HP Ingersoll Rand mannequin with an eighty gallon tank. At the eighty PSI required by my Dynabrade sander, the compressor would produce enough air from morning to night. I must say that that compressor was very effectively built. All I needed to do was watchthe oil stage in the sight glass. At night time, I'd turn off the master air valve on the facet of the air compressor, leaving the electrical energy on, to silence the compressor till the following work day.
I must assume that, having read this far, you have got some interest in using an air compressor to power air tools in your wooden shop. Almost certainly, a 2-stage reciprocating air compressor will fill the wants of a small to medium store. As a rule of thumb, a 5 HP air compressor will power one sander, a 7.5 HP machine will power two and a ten HP machine will likely be needed for three sanders.
The size of the compressor's air tank is an important factor: The smaller the tank, the more often the electrical motor will need to cycle on and off, That is exhausting on both the motor and compressor pump over time and it makes use of more power. I might never buy an air compressor used to function an air sander with less than a 60 gallon tank and I would really feel far more comforta
