I never ever want to be missing a forklift ever again. It just makes everything so much easier

[@bearsrodshop7067]

We got a glimpse of Elvis as you were in front of the ole yellow fan ! Had my nerves on end till it was safely on the slab. When thru the same motions when we picked up my Klopp 450 shaper, but the pallet it came on did fall apart after we had it secured to come-alongs, thank God! Still hold that day in memory, was the last time my Bride was in our shop. This July will make one year without her, so you cherish every moment you and Elisabeth have together, Bear.

[@whodat90]

Couple years ago I went to pick up my auction grinder, a smaller brown and sharpe. Guy said he had a forklift on site, so I only brought my small trailer, no tailgate, no tools, no lifting equipment. He did not in fact have a forklift. There were a couple people picking up equipment in the same predicament so we all got together to see what we could do. Found a pallet jack, put it under the grinder, pulled it out to the center of the floor where the wheel of the jack broke. Then we tried the same thing and started using the pallet jack like your toe jack, busted up other pallets as cribbing, and jacked it up about a foot before it became sketchier than any of us could tolerate. Finally we put all our tools in a pile and started brainstorming. We had a kelly bar, some 1/4" plywood, a floor jack, and a come-a-long. We made a bunch of suggestions, all of which were unfeasable. Finally one of the smartest people I ever met, one of the other guys, said "Take the wheels off your trailer". Holy cow. Took the wheels off the trailer which dropped the back all the way to the ground. Put the plywood on the deck so it had something to slide on, used the come-a-long to pull the grinder into the trailer, then used the jack to put the wheels back on. I gave the guy the last $40 I had in my wallet so he could buy some lunch, he immediately took it to the seller and said 'what else do you have?' Ended up getting a nice rotary table. That learned me my lesson, I never go to pick up equipment anymore that I don't take the big trailer, the winch, tools, and my modified engine crane.

[@garymallard4699]

Yeah when i go picking something up i take way more than i need in case..better to have it if you need it....and when you find they can't help you you don't waste a trip or fuel or time or....frustration !!

He really made it look easy in fast forward. But I'm gonna tell you from personal experience it's not. Would never do it again --- I would not recommend this method.

[@scroungasworkshop4663]

It’s funny because I see a lot of blokes trying to get their machines off pallets whereas I put mine on them. To be more precise, I build a custom wooden pallet as solid as possible to suit the machine that’s going to sit on it and for my pallet jack to lift it. Then I can move them around my shop on my own in complete safety. It also makes cleaning and maintenance much easier. Another bonus is I’m 6’6” / 2 meters tall so the extra height is very welcome. I love the channel and I’m looking forward to seeing more work on Jonny Cash. Cheers, Stuart 🇦🇺

[@timc3600]

Steve has too much time on his hands -- time to cut a glass bottle with no end purpose. What's the world coming to :-) Love the content. Keep it up. This video reminds me of when I purchased my Sieg Lathe. It turned up on a pallet and the delivery company dumped it in the middle of my garage. I hadn't even though about how to get it out of the pallet and into service. Luckily, an elderly neighbour and a good friend knew a thing or two about this, he turns up with a bunch of pieces of scaffolding pipe, wooden wedges, a jack and a large metal pry bar. We spent a couple of hours getting it off the pallet and gradually lowering it onto the scaffolding before we rolled it into position and down onto the ground before fixing it down and levelling the bed. His wise words at the end are that I've got a lot to learn and on reflection, he was right. I've learned a lot about machining in many more ways than I thought when I hit the buy now button. This is the same person that last week called me to say that their computer was broken and roles reversed and he now is up and running again. Never underestimate the power of your network of friends and the experience they have.

[@paulhunt598]

The grinder performed well. The bocks measure consistently and you liked the surface finish. The machine way belly wear may prevent large part flatness accuracy and your test set up could not determine this. BUT it looks very promising. Grinding is more of an art than machining. There are so many subtile dynamics that don't affect machining and typically we grind for greater precision and accuracy raising the skill level bar substantially. I have no hobby shop surface grinding capacity in my hobby shop. I am still trying to master machining skills. You are light years ahead of me as an operator, but I am an experienced repair technician. I have long enjoyed diagnosing machine accuracy. As a repairman I relied heavily on operators to perform test operations, but I designed and managed the processes. I could have a lot of fun collaborating with you if I lived closer. I enjoy being part of your journey. I am taking a new step in my journey. I am completing preparations for hosting and teaching intro to machine shop to a group of homeschool boys. My 12 year old grandson spent a day with me this week purchasing and prepping materials for our student class projects. I taught intro to electricity and troubleshooting to a similar group of boys. That was fun and I am very excited to begin the new adventure. Mr. Pete has inspired me and is a long distance coach!

Seeing that grinder brought back bad memories. I ran one of those all day every day making graphite blank cubes for EDM machining. The graphite was so fine the dust went right through my uniform, 40 minutes of scrubbing in the shower after work every day.

[@SeanBZA]

Try graphite based grease, takes months to wear out of your skin. Especially when it mixed with the Areoshell hydraulic fluid, to make a nasty sticky paste. We found a good way to wash it out, which involved a 44 gallon drum with no top, a gallon of the detergent from the high pressure cleaner, and a 4 hour boiling in the drum with a hot fire under it, then leave to dry, and boil again in fresh fluid and water, then rinse, and wash as usual. They went very faded after a half dozen cycles, but at least were clean.

[@bradleyfrederickson9536]

Hey a tip for those hose clamps you are using for the lubricant. The screw driver you were using is actually the same size as the hex head on the clamp. Just take the flathead tip out and use it like a socket and it makes them way easier to fasten plus a little more secure.

[@Hey_Its_That_Guy]

Little off topic. But I noticed in the shot with cora. The floor looks great. No noticeable settling or cracking. Still amazed by the work you did on your shop.

[@SteveSummers]

I've had zero issues with the floor. It hasn't settled or cracked . I'm really happy with the way it came out

[@jonathangriffin1120]

Great seeing the B&S surface grinder doing the job so well, casting my mind back to my apprentice days I remember using Jones & Shipman surface grinders, I'm pretty sure they didn't have filters for the coolant, instead, after coming off the machine the 'suds' would run into a tank which contained a flight of settling trays where the coolant would overflow into the next one progressively dropping out the solids on the way to the bottom from where it was fed back to the machine. Love the little calico kitten, looks full of potential mischief! All The Best from Somerset, England.

[@hilltopmachineworks2131]

When I brought home my shaper it was on a pallet. I had to do what you did to get it on the ground. It has been a hot one here too.

[@ianwilson7693]

Steve. Im not a machinist but i do have a lot of experience in measuring things. I have an observation to make on your testing of the grind. It is much more diffcicult to describe in words, I wish i coud darw a diagram. Any way, here goes. Because the chuck moves under the grind wheel, and, you ground the chuck prior to the block test, it is inevitable that the 6 blocks would be the same depth. you are, effectively, measuring the same distance 6 times. i suggest your measurements are an indication of how consistent the wheel itself is. i would venture to suggest that, because of the grinder design, the over-riding influence is the surface quality of the wheel. this is no way meant as a criticism, i offer this, for what its worth, more as a point of discussion. thank you for a brilliant channel, i look forward to each new video. btw, thats one cracking dog youve acquired, what a gem she is. regards from across the pond

[@marcellemay7721]

As surface grinders go, that's the Mercedes of grinders. Love that grinder. I have a little Harig 6x12 grinder and only the cross feed is automatic...I have to turn the X=axis by hand on each stroke. I bought mine at a school auction about 10 yrs ago, only paid $300 for it. It is accurate as the day it was made, even though it's a little smaller than I would like, it's plenty good for what I do. I hardly ever use it. It just sits there and collects dust most of the time. I actually made my own precision flat stones on it with a diamond wheel that I bought that was in a box full of mostly brand new grinding wheels I bought at some other auction. I love machinery auctions but unfortunately there aren't many here in east TN, plenty of farm and construction equipment auctions though. In CT where I'm originally from, machine auctions came up monthly.

[@tda2806]

Time for an indicator lamp for the mag-chuck? Perhaps a small lamp on the junction box on the side of the chuck? BTW like the Dorset flag, I'm sure you'd get a warm welcome here if you ever make it to the UK.

If I was carrying out the same task, massive destruction would have occurred at 8:47, as the long 4x4 balanced precariously atop the toe jack catastrophically failed in the unknowable depths of that massive knot. Glad you survived, Steve! I surely would have not.

[@wags9777]

I love my bosch hammer drill. Rocks, concrete, morter it doesn't matter

[@SeanBZA]

Yes, drilled a few holes with a 5mm bit, and only noticed after around 5 the tip was missing, must have snapped off when hitting some rebar. Made no difference to the drill though, went in exactly the same for the remaining 20 holes. Shame about the bit, it had been used to put in 12km of lighting in a shopping centre, all the back of house lighting in the car park, and the utility corridors, drilling 2 holes every 500mm for saddles, and then 2 holes for every fixture as well. Still got it, ground it to a sharp point, and used as a scriber now. The Bosch bits are good stuff, along with the Hitachi/Hikoki ones.

[@JM-hy2ve]

At first I thought you were going to suggest burning the pallet out from underneath it but then as you were explaining your plan with the chainsaw I started to think this may be your last video, good to see you made it, I can’t think of anything I have done in the past few years more exciting then trying lift and lower equipment that weighs a few thousand pounds by hand, if you haven’t tried it is a real thrill

Good rigging is done to a plan, at a steady pace, with no surprise moves, and not always with fancy equipment. Good work and good score with the grinder. Blessings from South Africa.

[@SeanBZA]

Yes, most of my rigging has been done with a 1 ton chain hoist, that I bought from a now defunct hardware store, and it has served me well. 1 ton rated, but has been (ab)used to do many things, including being used with a racking beam as a puller for stuck shafts, and for lifting up machines close to 1 ton, because of the need to repair them. Drilled a few mounts into the concrete beams and roof as well, using 1 ton eye rings, and M12 Rawl bolts, along with a good fill with construction epoxy from ABE as belt and braces, just in case the Rawl fitting ever wanted to come loose. Hard to come loose when the entire fitting and bolt, including thread, is filled with epoxy, though getting them in was difficult as you filled the hole, then left the epoxy to cure for 24 hours before use, eyelet and all now permanent parts. Think new owner of the building simply ground them off, and painted with primer, because they were never coming out. Did bend that 5 ton shelving stringer though, though it did do the job, but afterwards was bowed, and went as scrap metal eventually, as the shaft went back in this time with grease on it, not rust. One job pulled as motor off that burnt out, and only after struggling with it looked up the data, and found this was a 230kg cast iron frame unit, with the 300kg gearbox on it. No wonder so heavy to manhandle, the new motor was 83kg, aluminium frame version, and yes that beam was again abused to separate the two parts, as again OEM, and zero lubrication, aside from what blew past the oil seals. Motor died because the original installer wired to start in delta, and run in star, then upped the breaker to a 50A unit to not trip, and bridged out the overload as well. Ran for a few years, till it burnt a contactor to the point it dropped a phase, and then burnt out the windings. New motor, new control gear, and added in the biggest soft starter I could find, for this 8kW motor.

[@SteveSummers]

I agree, most the riggers I've seen in action use old jacks wood blocks and worn straps. They plan well and think about every move before they do it. In most cases they do anyway 😁

[@SeanBZA]

@@SteveSummers Yes had pro movers in for that, and yes they took 2 hours to decide just how to move, but no damage done. Same can not be said about the courier however..... Did have an old stainless steel tank that needed to go, and only option was to borrow a plasma cutter, and in 20 minutes the tank was stainless steel sheets on the floor. FIL came from work with his plasma cutter (container repairs) and a quick job to hard wire it into the board (3phase power needed for this big machine) and an air line, and before you can say smoke, it was done. Tank could not go out in one piece, as it was in there long ago, and the only way was to use a crane, and remove a window complete, and resale value was scrap steel price.

Here the cut is made using a glass cutter in a jig, and then a string wrapped around, dipped in petrol and lit, to snap off the top cleanly. Then sand the 2 halves, and epoxy the top to the base, and leave the paper label intact.

[@CoyoteridgeProjects]

I got all my machines off the pallets in a similar fashion I happened to have a couple of heavy angle iron that was a little longer than the pallets which then I jacked up the ends set on cribbing slid pallets out and lowered down in the same fashion as you did. The only thing I did differently is made stands under machines that had leveling bolts with pads welded to them and gave myself just enough clearance under the frame to get a pallets jack under some of the frames are wider than the machines just so pallet jack will fit but now they are easily leveled and easily moved around the shop especially if you need the room for a project and space is a premium they can be parked out of the way quickly. Good job at getting it done yourself 👍👍👍

[@SeanBZA]

Coolant system also would recommend getting a cheap water filter housing, 8in, and fittings to go to the hose used, and a 5 micron water filter cartridge. That way your cutting wheel gets a good flow, that does not have all the debris that misses the filter sock, and your cutting will have less marks left in it from tramp debris in the coolant impacting the surface. Filters will show dirt fast, but will keep the wheel very clean as well. Plus the restriction will also help with slowing down flow rate on the big pump. Tortie will have attitude, even though she is cute, and will be showing the dogs fast who is the boss there.

[@goptools]

Hey Steve. Many years ago I worked in a sheet metal shop. My main job was working a punch press (houdaille strippit). We had a small manual surface grinder used mainly for sharpening punches and dies. You are correct that an automatic machine is the way to go but, being able to take a break to sharpen punches, after finishing a job where you were punching 2 holes in a run of 1000 pieces, was a very welcome break. Thanks for the video!

Steve, fire polish the cut edges of the glass and avoid injury. An ordinary propane torch should be plenty hot, as a lab Bunsen burner is good enough for common soda/lime glass. Borosilicate ("pyrex") glass is beyond a Bunsen burner, but a Meker (grid top) burner works (been there/done that).

The easiest way to lower a heavy item is to raise it , replace the pallet with blocks or bags of ice. The ice will melt and gently lower the item to the ground. I have seen this done with a prefabricated concrete pool where there was no access around 2 sides of the pool.

[@theoriginalDirtybill]

Steve, you shouldn't restrict the inlet of a centrifugal pump. it will over load the motor, you can however pinch down the outlet as much as you want to adjust flow. it will actually lower the amp draw of the motor as you decrease flow this way. you would be better off plumbing the inlet at full size and put a throttling valve on the outlet of the pump

If your 90 deg. diamond is not at bottom dead center, you get a bit of up angle on it. The farther off bottom dead center it is, the more angle you get?

[@carlhitchon1009]

Thinking some more about this, I wonder what those six blocks prove beyond repeatability of grinding the chuck and then grinding something on top of that chuck. In other words, I don't think it tells us much about the actual flatness of the grind. It does tell us that the grind is following the same path consistently.

[@SteveSummers]

Moving the blocks to the surface plate and checking them there is where you see if the grinder is true or not. If I were to have placed the indicator off the grinder spindle head and check the blocks on the mag chuck it would have shown that the blocks were the same thickness even if they were different. It's moving the blocks to the known flat surface plate that shows the true path of the grinder spindle in relationships to the mag chuck.👍 I hope this makes sense

[@carlhitchon1009]

@@SteveSummers Hi Steve, love your show. My point is that the contact point of the grinding wheel follows some path through space which is not necessarily flat. After you grind the chuck, the surface of the chuck follows that same path. As long as that path is highly repeatable (even after you raise the wheel a bit to grind the blocks), the top surfaces of the blocks will also follow that same path. So those blocks will have the same height, even if the path followed by the wheel is not perfectly flat. What the test shows is that the grinding wheel follows a very consistent path, even after being raised above the blocks, but it does not verify that this path is flat.

[@paulhunt598]

Steve, This video seems a good time to add some similar rigging experience advice. Improve your method by using Rock Blocks. Jack only from one end. Raise the end and insert same height rock blocks just past machine weight centerline. Lower the jacked end until the opposite end clears the cribbing. Reduce the cribbing height, and jack the elevated end to clear the rock block(s). "Rinse and Repeat". Employing this technique allows you to never move the jack to the opposite machine end. Your toe jack is small and easy to move. If you are using your forklift or overhead hoist you will really appreciate the technique. You only need lifting capacity for "half" the machine weight and you don't require much opposite end workspace. This technique assumes a solid machine base profile like your machine. Pedestal machine bases like engine lathes likely won't accept the rock block technique. Most modern machinery in my experience employs a solid base perimeter allowing leveling jack screws around the entire machine base. The rock block technique improves ease, efficiency and often improves safety. Another tip(s) for using on size wedge anchors. Drill the hole entirely through the concrete slab. You won't need to remove dust for anchor insertion clearance and when the anchor is abandoned it can be driven flush with the floor easily. In a pinch, the same hole can be re-employed by simply driving in a new anchor. Also thread the hex nut flush with the top of the anchor before driving it into the hole. This greatly enhances stud mushrooming protection and accidental thread damage.
