Kaiser Schnitzel posted:Where was it made? The manuals on Italian stuff are the worst IME, at least for big woodworking stuff. With Taiwanese imports the importer at least usually tries to write a decent English manual written by a native speaker. India. Our best manuals are British from the 1960's, then the West German stuff, then Cincinnati from the 50's-70's. We have some modern Taiwanese and British manuals that suck equally, but are passable. This one takes the cake for vagueness. There is a screen with lots of empty buttons, so I'm wondering if something wasn't loaded properly as I seem to be missing a lot of poo poo.  We'll see what they say on Monday.

Does anyone have any recommendations for re-doing the surface coating on a metal cooking utensil? I recently bought a kitchenaid mixer secondhand, and the enamel is chipping off of the mixing paddle & dough hook. They're cast aluminum underneath, and I'm wondering either: 1. Is it feasible to powdercoat parts in a home shop? Are there food-safe and relatively DIY-friendly powder coating mixtures? 2. Would I be better served just stripping off the chipping enamel and polishing the surface to something smooth and easy to keep sanitary? Is aluminum fine to use with for direct food contact?

Ever spill laser printer toner? Imagine trying to manage a couple pounds of that that comes loose in a plastic bag and that's what you're getting into. The space you use for this will never be clean again. Small scale powder coat shops are a dime a dozen though, there's almost certainly one nearby to you that can throw your part into a run especially if you use a color they already stock.

I've got it coming now. We ran parts on it yesterday and after a few hours with metrology we have good parts! The rest of the day was spent tweaking the program and pneumatics. The auto gaging is really cool, every so many pieces it measures the finished length, adjusts the offset, and keeps on grinding. With it we can hold +/- 0.001" in length, which is really great. Cycle time is down to 7 seconds, but we'd like to see 5 seconds. We had a few surprises, like when you crank up the coolant flow, it shoots out the back of the machine. Whoops. So we had to fabricate coolant shielding so hopefully that issue is gone. Monday will be documenting setup procedures, making some fixturing for measuring, and bringing in QC for capability studies.

Anyone have a favorite enamel spray paint and primer? I’m gonna strip and repaint this vintage coffee grinder. I haven’t taken it apart to figure it out if the body is like cast zinc or sheet metal, if that matters. Definitely keeping it black and white.

Oh that looks like what I just found.  It’s been “professionally restored” you guys. Oh if you were wondering if they make replacement floor panels for like $100 like they do for pretty much all old cars the answer is yes. MonkeyHate fucked around with this message at 00:27 on Jul 13, 2023 |

I got an old table saw with a cast iron table. It's in mostly good shape, but the miter slots are a little dinged up. What would be a good way to clean them up while keeping them relatively square? Just ride them with a mill file and determination? Find the high spots on the face of the t-slot and selectively knock those down?

Might be overkill for table saw slots, but I use these for removing burrs on machines: https://www.kineticprecision.com/all-about-pfg-stones1 They work really well and don't cut into the original flat surface. Just takes the high spots off.

Correct way to remove surface rust ahead of painting? Going to hit it with Rust-Oleum gloss black nothing fancy but don't want to have to repaint it a second time as it rusts through. Chassis is about 8' long so I can't dunk it in a couple ounces of your favorite solution. Just power sand it with 200 grit? Or hit it with wire wheel?   I also have a bunch of inside 90° welds I need to dress that have gotten rusty, just gonna hit them with the angle grinder I guess

They look handy, but unfortunately they're wider than the miter slots and cost more than I paid for the saw (lol). Hadlock posted:Correct way to remove surface rust ahead of painting?

I'd hit it with a wire wheel, slather it with Naval Jelly or similar, plastic wrap it while the jelly works, then clean & dry thoroughly before applying whatever I was gonna apply.

Evaporust makes a gel that does a good job of sticking to odd shapes but its kinda messy to clean up and doesn’t seem to have much of a shelf life. Lately I’ve instead just been using paper shop towels wetted with evaporust and laying them in those awkward places I can’t easily get with a scotchbrite disk. If you live someplace dry wrap some plastic around it and let it sit overnight.

Maybe it's my Midwest, that's-not-a-spoon view of that "rust" but scotchbrite or a high grit flap disc, slap a metal primer on there and paint it. Swap the primer for a rust converter like POR-15 if you want but that would be overkill.

I've been looking into what I'd need to replace the motor on my lathe with a 3-phase AC one + VFD, in case the current one shits the bed, as that seems to be a common approach people take with these import machines. The whole installation & such I've got a grip on. One thing that eludes me however, is why the input current of a VFD is so much higher than its output current. For instance, the 230V 1.5 kW VFDs I've been looking at claim an input current between 13 and 15 A, and an output of 7 A. Why is it so much higher? Conversion losses?

Okay. Okay. So I bought a shop apron and I like it a lot. It has a lot of handy tool pockets and protects my clothes. It’s just really so very nerdy. I might rather my wife catch me with gundams or furry porn, but I put it on and my scribe and micrometer and sharpie and everything is right there. No more “where did I set that chuck key” because it’s always in the same little pocket. Don’t judge me it’s my new true garage skin.

There are a few different current ratings. If those are fuse/breaker recommend sizes then that is due to the high peak currents and poor power factor in a cheap VFD. The other reason would be if those are marketed as a single phase to three phase vfd. Then the input current would be square root of 3 higher than the output plus conversion losses. So a drive with three phase 7a output would need 12.1a single phase on the input. Factor in efficiency of 90% and you get 13.5a input current.

Yes, these would be single phase to 3 phase VFDs, so that'd explain it. Thanks!

Anyone got tips for fabricating with 4130? I have a flange-mount motor that I need to convert to foot-mount. I'm thinking the easiest way to do that with the tools I have access to would be to buy some of these U-bolts from McMaster, make a simple baseplate to clamp the motor to, and rig up something to cushion it a bit and dampen vibration. The metal I have on hand is 1/4" 4130 plate, likely hot-rolled. I'd be working it with an angle grinder, a drill press, and probably some files and a hacksaw, might tap holes into it. What are the pitfalls to watch out for? I rarely work with anything where heat-treatment and work-hardening need to be considered.

You aren't hitting it with a torch or welding it? If no, you probably won't notice much difference.
