    500VA buck boost transformers

    Pair of Acme electric model T181058. Purchased from McMaster last summer, installed and energized for about 10 minutes before realizing I had an internal machine issue, not a voltage issue. Removed and have been sitting in their boxes since then. Here's specs from McMaster. link Cheapest I...

    Cost for new construction engineering/site plans for metal building

    I'm starting back down the road of getting a new building constructed on a piece of commercial land I've got. I got a proposal back from a contractor that seems reasonable (at least for the times we're in), so to move forward, he requested I get a topo survey done (which I've ordered), and...

    115v motor vibrating/buzzing only when under power - not when coasting

    I've got a vertical bandsaw with a 115/230v 1 hp motor, currently wired for 115v. Recently, it's started a very loud (probably amplified by the thin gauge sheet metal cabinet) vibration or buzzing when under power. Motor still does it with belt removed, so clearly in the motor, not the rest of...

    Buck/Boost Transformer sizing

    Just moved my shop to a different building. Had 240 single phase and an RPC, new place has 3 phase 208v. Wasn't sure which machines would be happy on 208 and which wouldn't, so (also partially influenced by a lack of time) figured I'd hook them up and see which ones weren't happy. Seems to...

    Metal building insulation options

    I almost put this in my ongoing thread in the owners section, but figured it would get more eyeballs here than 4 pages deep in a thread up there. About to be building a metal building on commercial land. 40x60x14'. 2 12x12 doors, 2 man doors. Gulf coast, so AC is the consideration, heat is...

    Piranha Oversize/Whitney Ironworker punches - 28XX, 100XX

    A bunch of ironworker punches for sale. Ended up with these mixed in with a lot of Geka punches I was buying. Covered with surface rust, but should clean up. Many are sharp, with excellent edges. Some are worn. Let me know which ones you are interested in, and I'll photograph that die...

    Building a new shop on commercial land

    A couple months back, I inquired about moving my shop from a leased commercial property to a home property while moving to a new state. Lots of good feedback there. During that time, I was second in line on a unicorn of a property with a shop already, and for awhile, it looked like the first...

    Moving business from commercial location to home, what should I look out for?

    Wheelieking, I'm looking at you. Backstory, I run a small fabrication shop, currently in a leased commercial location. Been here since I opened in late '12. Pretty much a 1 man band, save for some part time (cash) help once in awhile, and probably plan to continue as a 1 man show. Every...

    Steel rule die tonnage requirement

    I need to make rubber washers (just a spacer) with a 2" ID, 2 5/8" OD. I've been using .063" neoprene, 50 or 60 durometer. A few years ago, I made a little cutter out of 2 sizes of thinwall steel tube, sharpened and welded to a plate. Would press onto a piece of 1/2" UHMW, in a bottle jack...

    Sole Source letter

    I recently quoted a project for a local police department - minor modification to a search and rescue boat. Got an email from my contact in the PD, and was told that due to the project cost, he'd normally have to get 3 bids, but he can't find anyone else in the metro area that does this sort of...

    Geka Hydracrop Press Brake Attachment

    I recently purchased a Hydracrop 55 that came optioned out more extensively than we need. Press Brake attachment for punching station. Complete, includes installation manual. Only thing to note is that the factory M18 upper bolt has been replaced with a section of 5/8 allthread. Asking $750...

    Breaker/wire size for hard starting 3 phase motors

    I've got an American Rotary ADX-20 (digital series 20 hp idler, rated to start 10 hp). It's fed from a 70 amp single phase breaker, and 4 gauge wire, per AR's spec sheet. No issues there. For awhile,it's just been powering a CNC press brake with a 7.5 hp motor, 20.2 amp nameplate. Knowing...

    WTB 10 gauge shear

    Looking for 10 gauge shear with backgauge. Ideally 10', but will consider 8 or 6' for the right price (no smaller than 6). Old mechanical is perfectly fine. Anyone work at a shop that has one collecting dust?

    Source for EP-3 grease

    I have a machine that calls for Mobil Lux EP-3 or Shell Alvania R3 grease, but I'm having trouble finding it in the US. Seems to be available more overseas. EP-1 and EP-2, no problem. Alvania R2, no problem, but can't find the 3 in either brand. Looking for grease gun cartridges, and...

    Surge protection recommendations

    Got a new CNC press brake on the way. Salesman and install tech have both highly suggested some form of surge protection. I've seen all types of surge protectors - some device specific, some that supposedly protect the whole panel (but only need to install in an empty breaker slot), etc. New...

    OT: Vinyl window screen bracket

    House we bought about a year ago came with brand new vinyl windows, but I don't know what brand they are, or how to find it. About half of the windows have these little brackets that make installing screens a cinch. I'm guessing the installer got lazy on the remaining units, and never stuck...

    Issue with dual voltage 3 phase machines?

Have single phase power only, just bought a brand new American Rotary ADX-20 (20 hp) phase converter. Looking at 7.5 - 10 hp machines. A machine dealer just mentioned to me about...
