The Air Compressor at Lingua Franca
"Hi!
We currently have the compressor in-house in our machine embroidery production studio. It's been working great for us!
Thank you for reaching out. I've attached an image of the compressor in our studio.
Best,
Natalie"
"Saw works great. Just what I needed. You may want to update the specs though. It says 110v but it’s 220v. I don’t think it will an 10” saw blade either. Haven’t tried but I don’t think it’s set up for one like it says. Ordering process was nice and easy. Thank you."
"Got the JLT #717C for our shop and it’s an absolute beast for narrow stile doors. The 2-second squaring cycle is legit—we’re easily pushing 100+ perfect doors a day now without stressing over glue joint alignment. Setup is super fast with the pin system, and the heavy-duty build takes daily abuse without losing accuracy."

Thanks for the service!
"Here are 2 pictures of the glue tank in our shop. I hesitated to send anything as it is not in its final place but perhaps it's good enough for you. We are using it for our drawer box station and assembly station. Thanks for the service!"
"haven't had a chance to use it but it looks like a well built product have a few projects down the road and I know this will meet my requirements. so hats off to your team! David"

Both Tools Work Great
"Both tools work great and are real time savers . The two tools that I received from your company were replacements for the exact same tools that I've used for the past years, I think its safe to say 20+ years. Extremely pleased with product and service."
"Bought this California Air Tools compressor for the shop and it’s an absolute game changer. It’s incredibly quiet—you can actually have a normal conversation right next to it without yelling. It fills up fast, keeps up with all our nailers and blowguns with zero issues, and the oil-free pump means no maintenance. If you're tired of loud, annoying compressors ruining the vibe on your floor, grab this bad boy. Worth every penny."

Heavy Duty & Precise
"Brought this Jet 16" x 40" Engine Lathe into the shop recently and it’s an absolute beast. The 3-1/8" spindle bore is exactly what we needed for turning larger bar stock, and the geared head runs incredibly smooth from 25 all the way up to 1,800 RPM. It handles our heavy daily metalwork without breaking a sweat, and you can see how solid the build is right in the photo. If you need a reliable 3-phase lathe that holds tight tolerances all day, grab this bad boy. Worth every penny."
"I believe they are working well judging by none of the guys have said anything about them other than a thank you for swapping them out for them hahah. So thanks for checking in."
A Weldon shank is a round tool shaft machined with one or two flat sides so a set screw in the drill's arbor can bite down and lock it firmly in place, preventing the cutter from slipping or spinning under heavy torque.
The industry-standard Weldon shank measures 3/4 inch (19.05 mm) in diameter with one or two machined flats, matching the arbor on most magnetic drill presses used for structural steel work.
The most common is the Weldon shank, a flat-sided shaft locked in place with set screws, while a quick-change or universal shank snaps into a proprietary quick-release arbor for faster bit changes without tools; some mag drill brands also use threaded or one-touch shank systems.
