I have a Sherline 5400 mini-mill, so steel is just about of the question anyway. In fact, I have trouble with more than 0.002" deep cuts in 6061, even with a tiny 1/8" bit. It's truly a hobby-level machine. My dream is to create some very clever, small, marketable things with it, to help save up for a sweet CNC knee mill, and then I can think about RP ABS machines, and powerful laser/water jet engravers/cutters! :) I've seen many Lymans in my hunt, and with 0 experience, am unsure which one would be comparable in noise, power, etc., to the Harbor Freight model, and which might be better suited for my needs. The HF model is so cheap, though, I think it's worth giving it a shot. I can always find an alternate use for it, or Ebay it off to someone needing to clean shell casings if it doesn't work out for me. Then I can reveal any good experiences here. The noise permeating the house is a bit distressing. If I have to run something for say, 10 hours, it would be nice to just let it run into the late evening to finish up. I'm doing all of this mini machining in my office, in a house with all wood floors (so no sound is ever trapped by rugs, or carpets), but I've been surprised how much sound is killed just by the ancient walls. I had the mill cutting at full throttle (2800RPM), and this shopvac running at around 11PM this weekend: http://www.homedepot.com/webapp/wcs/stores/servlet/ProductDisplay?storeId=10051&langId=-1&catalogId=10053&productId=100388637&marketID=48&locStoreNum=6611&categoryID=524502 I decided to finally see how loud it was for the neighbors, and went outside, and really couldn't hear it much when between our houses. Inside their house, through yet another wall, it would definitely be entirely silent. The ambient neighborhood sounds of traffic, and wind were louder than the very faint whir coming from my windows. Having lived in an apartment for years, with seemingly acoustically transparent walls, I've done a lot of research into soundproofing. One of the things I'm still keen to try with everything from the shopvac, to this vibratory bowl is anti-vibe mats, like these: http://www.soundproofing.org/infopages/flooring.htm And even foot pads, like these: http://www.soundproofing.org/infopages/vibrationpads.htm Another thing I'd love to try to really kill machine noise is a method I found on that site for building nesting boxes. Each is missing its bottom, and one side, and you nest them such that each larger box slides over its smaller, child box's open end, creating an opening that zig-zags back and forth from the inside to the out. Air can travel easily through this, but sound doesn't like turning corners. If you line the insides of the boxes with that anti-vibe, or sound-trapping stuff, and set it all up on a sheet of it on the floor, it's supposed to tremendously deaden machine sound. This would be great for something like a vacuum, which can be hidden away. The biggest problem is heat, but fans could probably be added to the setup to push air through the zig-zag channel. Maybe I could even run a pipe in there from my portable A/C unit to blow out the heat. Anyway, thanks for the info! -Gary ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
