    Nitrogen for plasma cutting aluminum?

    I've only cut 1/8" aluminum on my plasma table a few times with compressed air and the cut edge was pretty rough and grainy. Would using nitrogen for the gas produce a similar edge to carbon steel cut with compressed air? Would submerging the part on the water table help the cut quality in...

    I was asked to quote a fold up window, basically a horizontal bifold where the sashes fold up into the room. Is anyone familiar with what balance/mechanism is used in the jamb for this style of window?

    Protection film for press brake dies

    I make some parts from 11ga-1/4" HRPO that get bent in the press brake then sent off for powder coating. I'd like to prevent the die marks so I did some searches and found the polyurethane film in a couple thicknesses. Does it matter what film thickness I use and/or can I use one size film for...

    Trouble shooting ironworker motor

    I've got a Geka ironworker that was making additional screeching sounds on top of the typical hum when the motor is powered on. I opened the mechanical cabinet below and the hydraulic oil reservoir looks normal, the gauges both read zero while the machine was idling and when I cycled it through...

    What's a good insert for dry turning 304 stainless?

    Having a little trouble getting a decent finish on some 304 weldments I need to turn down. Parts have a brushed/satin finish so the surface doesn't have to be perfect, but the smoother it is the easier it is to apply the brushed finish. I tried some ccmt and cnmg inserts with mixed to bad...

    Knee mill with Trak AGE2 controller

    I'm considering replacing an old clapped out Bridgeport with a knee mill in better condition that has a Trak AGE2 controller. I believe SWI still services and has parts for their older controllers, but I have no experience with them. All the parts I make are pretty simple, but It's getting...

    OT autonomous filming with a drone

    I'm interested in producing some marketing videos and thought about utilizing a drone that can capture unique vantage points and be setup to film autonomously. I've never used one, but I searched a little bit about them and figured I'd be focusing on models that have a 'follow me' feature that...

    Bridgeport table slop options

    I read a few threads on the various symptoms and solutions for table slop so I'm relatively familiar with what's going on with mine. Typical older mill with worn ways and feed screws. I took the table apart to remove the hardened grease and familiarize myself with how everything ties together...

    Fronius 2700 mig welder, anyone have experience with these? I need to replace my mig welder and considering the Fronius 2700, but don't know anyone with real time experience using one. Mostly for carbon steel and stainless, however I might have some aluminum work coming down the pipe. From the...

    Replacing babbitt bearing on edge sander

    I've got an Oakley H5 edge sander that has a loose babbit bearing around the oscillating mechanism shaft in the cast iron frame. It looks like the bearing will have to be melted out and poured in place which I've never attempted before. I've found anecdotal comments online about the steps...
