GFCI is never going to play well with a VFD setup like that. I had similar issues with a diamond wheel/solid carbide scraping tool grinder I built from a double shafted 3ph 1/4hp motor from a scroll saw. Same type of VFD. Make sure all ground paths are solidly connected to your machine and...

Fish/pull in the neutral wire from the panel and update to 4 wire receptacle.....is there an easier choice?

At least AI got to make a response :rolleyes:

I believe Farmall had a similar kit for inflating these new-fangled rubber tires starting in the late 1930s, it screwed into a spark plug hole of your choice with a check valve. My concern would be that unlike the compressor V8 classic design, the cylinder in question was not isolated from the...

The way I envision the design is that the shaft is vertical and a cable sheave runs at the midpoint. Its loaded in a horizontal plane. Here is bending moment supplied by the internet for a simply supported beam (although rotated 90 degrees), I think that's the correct application here as the...

Ye olde "pulley tap" comes to mind. Grease will choose the path of least resistance so may have to put one in each side of the sheave.

That is big boy money right there! Kind of like owning your own CNC water jet or personal jet 😀 Suppose a person could get lucky at an auction and win pallets of bus and bus plugs for peanuts, the utility install and copper to feed it for 1000A makes me start to sweat thinking about the cost...

Like the idea of a zerk but the other guy had a shaft snap/twist/fatigue to full cross section failure. I could not see it in enough detail to make a better guess as to why. However, drill and cross drill reduce cross section especially at the center of the span where bending stress is peak...

Don't know 100% of the details of your machine but possibly this can help. If you can get this style of squeeze bottle and fill it with any ATF, you can "overlube" any interface between stationary and rotating to the point of dripping off, ideally you'd have catchment (rags, cardboard, PIG...

Always good to think about what is resisting the torque on the moment spring as you wind it up from the free state....its the flange attached to the center support....(!!!) I have wound and unwound several. I always use a piece of W1 drill rod (annealed/as-purchased state) which has a little...

There are a couple of ways. First would be to build a structure (could be wood or metal) spanning the top of the posts so that it could be leveled and the load relieved with come-alongs and or chain falls. It could even be threaded rod, nuts and washers, if you had that material and some...

Lol. I don't think I have 1 hour of motor-on compressor runtime in 5 years. I've changed it once in 30yrs. It's non detergent so solids settle out to a quiet place in the sump. There are no hydrocarbons.

I think it's the rabbits because that's the only animal I see, but they chewed the plastic grating end off my PVC sump pump discharge pipe. Just the outlet end. It got frozen in winter and I think they wanted the water...

Looks like AI got to put in a response too 👍 Use angle grinder with thin cutoff wheel or traditional grinding disc to attack the outside corner of the formed metal section. In other words get rid of the angle iron and separate into flat strips that have much lower ability to "fight back"...

The top "trunk line" is a fairly future proofed solution if you have enough diameter in the trunk. Yes this costs more now but you have the wireway 95% built for any future needs. Without sufficient diameter a person would have to start from the (sub) panel again running wireway. A building...
