    Removing mill scale in cold weather

    Curious - the drums are a bit spendy. How long do the drums last?

    I do the same with my rattle cans inside a semi-insulated flammables cabinet. Thanks for the feedback. Rick

    Removing mill scale in cold weather

    Thanks. My thought as well. Looking at how I'd set it up. I'm looking at a 150qt. Igloo cooler that could fit the bill. Whereabouts are you in SE WI? I'm in New Berlin. Thanks again, Rick

    Removing mill scale in cold weather

    Intriguing. Thanks for the suggestion. Looks like it has other uses outside of stripping body panels. I'll take a peek. Rick

    Removing mill scale in cold weather

    3 primary reasons: Welds flow better when it's removed The extra layer removed makes it easier to telescope tubes inside of each other Looks better (to me at least)

    Removing mill scale in cold weather

    Most of what I'm doing are pieces of square and rectangular tube with flat and plate thrown in for good measure. Most pieces are 3' or less. Plate might be 24x24. I'm going to try some of those, but I prefer how vinegar works. I'm thinking that a large cooler might help keep the vinegar a...

    Removing mill scale in cold weather

    I've had good results using a white vinegar soak for a day or 2 to remove mill scale from steel tube and flat bar. The problem I have is that my garage shop hovers around freezing most of the winter. The cold inhibits the ability of the acid to do it's work in a timely manner. Been noodling...

    Hoist Mounting Suggestions

    I have the same need, and the same frequency. My thought is to secure one end of the gantry to the wall, with the I beam secured to the joist using some all thread and wood blocks. I'll remove the other post of the gantry and tuck it in the corner. When I need it moved, I can easily bolt on...

    My Compressor Aftercooler Install

    A buddy of mine in the HVAC biz had a chunk of 3/4 I used for a pump/compressor rebuild. I'd check with a local contractor and see if they have any short lengths they can get rid of. Rick

    Vinegar strength

    Hey all... For years I've used everything from naval jelly to electrolysis to wire/flap wheels to elbow grease to remove rust and mill scale. Even tried some muriatic acid (worked great but way too many fumes). Recently, I've been using white vinegar with mixed results. First time I tried it...

    20Hp Rotary Phase Converter Questions

    Compressor motors are another beast altogether. Inrush current is significant. You will want to consider upsizing your panel to compensate for that current.

    20Hp Rotary Phase Converter Questions

    I went your route a number of years back for a smaller (5hp) RPC. Worked well, but it was very time consuming trying to get things tuned. I have a 10hp and 20hp motor that I'm considering as a base for another RPC, but I'll go the panel route instead. Have you considered purchasing a...

    Options for dismount

    I want to thank everyone who provided insight and suggestions. I did not want to hire someone and wasn't keen on asking friends to risk injury. I knew I had the tools to get the job done - just needed some time to think it through. In the end, I ended up modifying the hoist a little, and the...

    Options for dismount

    Folks, I picked up an 80 gal vertical air compressor. It was loaded on my trailer with a forklift. The problem - my engine hoist isn't tall enough to be positioned on the ground and still be able to lift the compressor off the trailer deck. The compressor is new, so I'm reluctant to...

    New compressor - 50 or 60a circuit?

    I'm not using one. My breaker panel is only 10 feet or so from the compressor. Disconnect is old habit, but I'm not using a fused disco.

    New compressor - 50 or 60a circuit?

    Wire size - 4/4/4, with 6 bare copper ground. Distance from main panel - 42'. 200amp main. I asked the electrical inspector about the max circuit on the sub and he said 60 would be fine. Thanks, Rick

    New compressor - 50 or 60a circuit?

    One man garage shop. When compressor runs, I'll be running air tools (blaster, sander, etc.). Lights are all LED. I'm more concerned about startup. The motor will take 32a running. Plenty of juice left over for the rest. Thanks, Rick
