So I went to Home Depot today, armed with some scratch and the will to buy an air compressor and a DA air sander.
HD sells the husky line. So, I went to the tools, found a DA sander (Husky, needed 4cfm @ 90psi, and the box said it would work continously with 20+ gallon compressors). Then I walked over to look at compressors. They had a Husky 24 gallon compressor that flowed 5.1 cfm @ 90 pis on sale ($225). Score! but then, on top of the motor, was a little chart with reccomended tools and non-reccomneded tools. All sanders and DA sanders were non-reccomneded. I called over a HD floor guy, who called over another 2 guys, and we could not see a good reason for the prohibition. But, we decided that if the factory did not reccomend it, then it should not be used as such, and I walked over to the electric tool section and bought an electric DA sander. (IMG:style_emoticons/default/sad.gif) I am going to need to buy a compressor by the spring. I'm clearly in the "hobbiest" catagory, and may not use the tool again for a long time aftyer I am done with my 914, but when it comes time to paint, it will probably be cheaper for me to buy one then rent one - given the slow nature that I work. I want to know why the sander was not reccomended, when the compressor could flow the air and had a big enough tank according to the tool. I have theories, but I thought somone here might be able to give better advice. Thanks Zach |

Regarding the PVC.....First let me say, I would use copper if you can afford it.. With that said, I used PVC. My shop is big and I have air outlets everywhere. No problems with 17 years of use at 150psi. I attribute that to several factors.
1. At each wall drop termination, I used a 2" long metal pipe fitting to an air coupling. I made metal brackets to attach them to the wall. When you pull on the lines, no pressure is put on the PVC, only on the metal to metal pieces. 2. All PVC is in the wall. No explosion worries and no sun exposure 3. The pipe and fittings were well primed and glued using commercial grade PVC cement. If you are considering exposed PVC, and it breaks\explodes you could do some very serious harm to yourself and vehicles that are close so be careful if you do this route. |
