You're not missing anything at all. We have run non "VFD spec" motors for decades with VFD's (just not on single phase) with no problem. The biggest thing that I know of is to make sure the size and type are correct for the intended use. As for a shaft ground ring, nope.. I added nothing to the motor, just connected to the factory ground on it, the inverter and the ground bar in the panel which is grounded to the rod for the panel. I actually have a ground rod at both panels in the building and tied them together since my ground is mostly rock and sand. VFD spec motors tend to mostly have heavier insulation on the windings and the ground rings is my understanding, but honestly a vfd can a three phase motor without them just fine. It's just a matter of the motor may fail sooner than without it, but we haven't seen it happen when we have put vfd's on non vfd spec motors. I am sure it has somewhere under some condition though. I have no doubt that the VFD I am using is not the "best" quality, or more durable for what I want to use it for, but it was affordable, easy to get quickly and would answer questions for me. Since it's on the air compressor it also doesn't need to run continuously either and will have cycle time. The real test will be when I want to run the foam machine and it either needs to run for longer duration or cycle more frequently. Even then I will take breaks between the sets of barrels to let the various equipment (myself included) rest and cool off a bit.

Thanks for the idea about auto transformers, hadn't even thought of them. Most my experience is with VFD's so I went with what I am the most familiar with, though I hadn't used one to convert from single to three phase until this project. As for the brand, I figured quick and cheap to test. If/when it fails I can swap to a better, or higher quality one. Since I am not there anywhere near as much as I want to be yet, the cheaper ones work for proof of concept and to get things working for now while leaving some money in the account to put towards concrete and foam resin to finish off the main building.. hopefully next summer if I can get enough done this season. Whoops.. you were referencing the Sol-Ark, not VFD with the Snyder recommendation. I have loved the Sol-Ark's overall and they actually have been great at handling everything I have needed up until this air compressor. I had an Outback Radian prior but swapped it with my father so he could have two and I could pair up the Sol-Arks. They work really well for my needs overall. Excellent customer service as well, at least when I have called with ideas/questions to run by them.

@@VowellVentures Yeah inverters that do not have transformers in them are mainly missing the surge power unless you really oversize your system. I myself did the research and Growatt 5k inverters and a auto transformer was the way to go. I could do 3 phase with mine if I add 1 more inverter but I do not power a garage with compressors. Auto transformers are not real expensive. you would need 2 at around $800 total.

The Sol-Arks have a pretty good surge power on them overall, just not a long enough duration and because of that don't like hard starting motors which I expected and figured I would end up working around. The have handled other heavy loads fine, just not this 5hp air compressor which to be honest, I didn't really expect it to just hoped it would. I also didn't expect to need this new air compressor as soon as I did either, so I thought I had time to finish my system. But when I finally found the specifications of the foam rig I have it became very apparent I screwed up when I bought my gas compressor and got one too small. Then it became time to figure out a work around solutions. All part of off grid and homesteading I suppose. My place is a bit.. larger and "different" than most for off-grid though, part of the challenge that makes it fun. I want a nice shop where I can think and putter to my hearts content and (with in reason) be able to run all kinds of fabrication tools for various ideas I have. I'll just stick our house in the back 3rd of it and call it good! Later I hope to extend the shop enough to make up for the space lost to the house too. I'll check out the auto transformers though, I haven't played with them or even thought of them to help with surge/in rush loads. Great idea actually. Thank you for the suggestion!

@@VowellVentures I wonder how the EG-4's would do, seeing as they have stupid long high surge run times. EG-'s 18KpV has PEAK POWER (SURGE CAPACITY) w/ PV: 14700W (10 min), 15500W (5 min), W/O PV: 13500W (10 min) for just one unit.

Hadn't heard of that inverter setup so I looked it up. Appears to have a lot of similarities to the Sol-Ark I am using. I really like these hybrid units overall. I see this for the EG-4 12K version, "Peak Power: .05s = 16kW, 1s = 12kW, 1min = 10kW, 12min = 8.8kW", it looks like two paralleled like mine are would start most anything just fine, still debatable for something as hard to start as a large air compressor. With the setup I put together I think I could actually use that same VFD on a 7.5hp air compressor if I ever decided to go bigger if Rolair dies on me someday. It's great seeing the solar technology advancing from all angles so rapidly! Gives a piece of mind that as the property grows, I can have the system grow with it and be able to use more and more efficient equipment. Equipment that gives more wattage per foot, takes up less space, lighter and easier to handle.. any or all of the above are great benefits to the technology advancing so quickly!

The only thing above the fan that I can think of would be the hydraulic oil cooler that I believe is on top of the radiator. When my coolant tank blew it flooded the cooler area and coolant shot out of the fan outlets. Maybe a hydraulic line to the cooler is leaking?

@@VowellVentures Ok will check when I open it up. Thanks.

@@KINGSTONSPRIDE one other possibility would be if your machine has a hydraulically driven fan instead of belt driven like mine. I don't know which years ran them, I would assume newer than my '05 though. Either way, kind of a pain in the butt to deal with since everything is so tight, but feels great once things are fixed and the machines are purring again! Good luck!

@@VowellVentures Found the leak. It was the bottom hose on the hydraulic oil cooler. It’s dripping down into the radiator onto the fan when running and shooting out both sides of the vents. Hopefully the new hose stops the problems. Thanks for the advice. Good day to you.

@@KINGSTONSPRIDE glad you found it!

This bucket has been great so far. Found a lot of unexpected uses for it so far. Someday I hope to add to the collection, but so far this has been great for everything I've needed so far. The grapple has made the difference.

My pleasure and thank you watching. Skid Mark has been a pain and learning curve, but it has been about the best tool I have bought for the homestead yet.

It was good talking to you! Definitely been a long time. Hoping to get a lot done this summer and share as much as possible here.

Thanks, with any luck I'll have them all powered up to show off by the end of summer! I have fun plans for control of them too.

No issues with them so far, even lit instantly with the building around -16f. Hope to have the rest powered up this summer.

Thank you for the kind words and the offer. At this time I don't think I am ready for outside help editing since I am not able to be on site full time to continuously create footage. To be honest, I am enjoying learning editing techniques and what all can be done with the software I am currently using as well. It is definitely time consuming and a headache at times, but it's still fun. Maybe someday when I am able to go full time and am living up there I might be ready for third party help, but I'm not quite there yet. Thank you again.

Actually have been, not good at it yet and I think something in the clutch is out of adjustment. Bearing in primary box are shot too but I have a spare trans. Truck has definitely been an entertaining learning curve and once I work a few more bugs out I can see it being a lot of fun to have around.

You wont regret it! Glad I opted for mine, it was surprising how versatile the bucket became with it.

I was actually a little surprised with how versatile it ended up being, and glad for it. I have you 7224 snow blower as well and took delivery just in time to test in on some of the most rotten, wet, slushy snow you could imagine early last May. It was great as well, only complaint had mostly to do with operator error actually, and that was the powder coating peeled off the auger and edges of the chute, but in fairness.. a lot more gravel, sand, and nastiness was getting sent through it than probably should have. Performance wise though, it was great on my T190 "high flow"(but not really compared to other brands) machine. It was still able to throw the slop an easy 20+ feet, I just had to be patient and not ram the 12-15" mess down its throat to quickly! LOL I have a wish list, and you will definitely be getting more orders.. I just wish you were close to Alaska for better shipping!

Great to hear@@VowellVentures! You're right on the snow blower...patience is key to keep it from bogging down, especially in that slushy wet snow. Also, when the ground isn't frozen or is a little soft, you can easily get too aggressive on down pressure, which means more rocks and stuff through the blower that we want to try and avoid. I'm guessing this winter you'll get another shot to really test it out and get proficient! Thanks for your past business, always great to hear from you.

This truck has the '71 500 mated to '76 TH400 to get the RWD needed, swapped the 14" tail shaft to a 4" Chevy one and hung a Gear Vendors splitter on the back of it. Worked out really well overall, but I geared the truck to the cam's efficiency instead of comfy highway, efficient driving. 3.73 in the rear with 30" tire, should have setup 3.42 or so to let the engine sleep when cruising. That said though, when towing it has no idea there is a load behind it regardless of the weight it seems! 🤣 Just eats more fuel than it needs too, oh... the 2200 rpm converter doesn't help either, but does make it entertaining on stop light! 😈

@@VowellVentures Now that's very interesting, you seem to really understand the workings of the engine and gears, plus tire size. They all make a difference to overall gearing. Most people don't understand the difference a tire can make, on overall gearing. A taller tire makes gearing faster, or slows the engine RPM for the same speed. I changed tires on a big truck from a low profile 22.5, to a tall 11R24.5 approximately a 6 inch taller tire, and my top speed at 2100 RPM from 72 MPH TO 76 MPH. With 3.55 gears . An overdrive transmission would have helped as well. I had a 9 speed direct drive. And a 350 horsepower Cummins engine 855 cubic inch.

I would love to swap a 7.3L IH diesel into the dump truck to use with the twin gear boxes if I can get them to work nicely.. going to be another project/video for that.. but have no desire to reset the gear ratio's in the twin 30,000# axles to work with the diesel's rpm range! LOL Almost leaning towards a Caddy swap into it in place of the tall deck 427 since I can make more torque with a closer similarity in rpm range, but would end up needing to swap to a TH400 setup instead of the twin sticks. I think the TH400 in Ol' Ugly with the GV behind it would take the abuse the way it's built and I do have a spare I can freshen up to use as well. But then the dump truck would lose its primary anti-theft device since most people can't drive a single stick manual let alone a twin stick! LOL Hell.. I can't even drive that thing well yet but in my defense, both gear boxes have seen a lot of better days! Keep an eye on the channel, while it is primarily supposed to be about the homestead/shopstead, there seems to be an awful lot of "old iron" repair and modification going on.. more than actual progress on the main project itself! Argh... I love old equipment, but man I wish I had it all in good shape already! LOL

@@VowellVentures I drove a 67 Chevy C80, had a 6V53 Detroit 160 horse power had a 5 speed and a 4 speed manual. Don't know what the gears were, twin screw with the 4 speed in 4th was an over drive gear, but less than 10% over drive. It took a while to learn, but I came to the realization that if it only had the 5 speed, that engine would have a lot of problems trying to move . It was a straight truck, a slurry truck. It had 2 tanks 500 gallons each. One for water, one for asphalt oil. ( emulsified, so it would mix with water) and a hopper for a combination of small rocks and sand. And it mixed it in the back and was used to seal asphalt streets and roads. It was a slow truck, the engine was governed at 2800 RPM from the factory. Top speed was only about 62 MPH

@@bertgrau3934 I think 62mph would terrify me right now in that truck! 🤣 I'm sure I can get it to behave and learn to drive it, just impatient right now! Would be sweet to fix it up a bit and take it to local car shows to see the reactions! Maybe a twin turbo setup on it or something.. low boost.

Sounds like a great truck! I swear the old Cadillac big blocks don't get the credit they should. They were designed specifically for turning slow and moving massive land yachts with ease. The torque output stock was insane!!! There is a video on my channel showing my truck, dubbed Ol' Ugly that shows my setup indirectly while I fight a power steering pump issue on it. Near the end of it I fire it up to check and.. well.. it's not quiet! LOL The '71 500 in it is .030" over bored to 507cid, MTS#10 cam, roughly 10:1 compression, Edelbrock manifold, Fast EZEfi v1 fuel injection (best mod EVER for it). The exhaust is log manifold to a 2 1/2" Y pipe I built, then single 3" through SpinTech 3000 series muffler. The truck is my pride and joy, though it's the second version I have built. It will end up being shipped to the homestead at some point where I can build a tube chassis for it and retire it to a life of drag racing on occasion. I'll end up building a third version first though by converting my 2000 K3500 in the background of various videos posted. Thanks for sharing about your truck!!! I love reading about other peoples projects, especially ones that have Caddy swaps in them!

@@VowellVentures Sir, very impressive! That sounds like a really cool truck. I will take a look at it. The 472 is a good engine as well. Thank you for sharing Sir.

@@bertgrau3934 yup, 472 is an awesome engine! I just got lucky enough to stumble across a dead Eldorado when I was looking for a fun donor.

@@VowellVentures That's cool, it already has the rear sump oil pan.

To be completely honest, I am a rank newbie to world of these trucks, and most equipment in general. That said I am a sucker for swaps in general, and have done a number of them in cars and normal pickups with. This truck and my other "dead to others" equipment have been a (usually) fun learning experience so far. I vote that if you can get your hands on the donors you need, and get them to fit.. if for nothing else than fun and smiles.. do it, and enjoy every moment of it! I'll keep puttering on this truck as well, hopefully I can get to cleaning up the body and box while slowing making it road worthy along the way. These trucks at a local car show could be a lot of fun I would think!

Nope, from TH-cam audio

@@VowellVentures Bruh moment

Was a vented fuel cap not an option?

Thank you and have a great weekend too!

We picked up those new ones at Ken's Garden Center there in Wasilla. Was hard to choose though.

There are no woods on Unalaska. Too high of winds out there. Three trees were planted in the 70's and they might be the only ones out there still on the Dutch Harbor side.

This was a fun video to make.

Thanks, it needs its love but it is pretty cool to play with.

I'm not a Chevy BB fan in general, but that is not a bad idea at all! Keeps it cheap, suits the "mod everything" mentality, gets the torque up and keeps my gearing the same. That's a lot of boxes checked!! Thanks!

@@VowellVentures it's what I did with my C60 and she moves 53 foot trailers loaded down with round bales without a problem. Used to have a 366 the first year I worked it.

Found 2 complete 427 engines and a complete 454. Made a 454TD for my C60, put a rebuilt 427 TD in my K30 3+3 and a 427 in my 95 caprice wagon. Have no complaints.

@@bladenrexroth2555 this is definitely sounding like a must do project! I need to swap my primary gear box (hopefully this summer) then figure out why the auxiliary is stuck in LL or L, but after those are taken care it might be time to find a donor 454!

@@VowellVentures aux boxes are notorious for becoming soup bowls. Years of winter and summer condensation gets inside of them and causes rust, bearing failure and gear teeth to become bluetooth. Bet if you cracked the drain plug on your aux box you'd see 2 gallons of water before you'd see oil. Depending on the last time it was serviced. Drain it and open the service plate. If you see rust? And if nothing metal comes out in the drain? Fill the box with kerosene and let it soak for a couple of days. Put some PB blaster on the linkage and see if it brakes free. Hopefully the aux box won't need much more than that. If it does? It gets expensive.

Makes sure you pin it ;⁠-⁠)

@@RyanWRoehlAKZoomberBoomer already did!

I'm hoping to get back sooner than later, need more time in the snow!!!

I sure hope so too! Slow and steady is fine with me though as well. Still lots of learning to do.

Very much so here, even supposed to have extra enforcement this year. 🤦🏻‍♂️

You're nuts! 🤦🏻‍♂️🤣

@@VowellVentures YEET BRO

Pretty much will with the pole barn, kills many birds with one stone that way. Gets the height and distance I need as well as giving me the equipment storage area out side the shop. I was toying with moving my solar to it once it was built, but I think I would rather double up instead. Still time to make up my mind though, still need insulation and concrete first.🤦🏻‍♂️👍🏻
