Incorrect, Distilled water used for cutting,50% alcohol used for welding. When alcohol heats up and converts to plasma which releases carbon gas in fact shielding gas that protect metal from oxidation.... Distilled water converts and produces hydrogen gas which used for cutting metals and other materials.... According to instructions there is 2 different types of anode cups with different hole diameters large for cutting small for welding,this is primary function 2nd function is 2nd power line which enable arc welding setup and also electrify surface,filling metal wire is normally grounded to prevent electrical shock,the negative polarity at 2nd power line absent and it would go on contact with primary (torch setup),avoid torch get close to clamped welding area to prevent short circuit,filling rod must be kept close but not too close to welding surfaces and torch must be kept about 0.85mm away from welding cache.... Process reminds between arc/tig to brazing technique,combination between both.... Since Multiplaz 3500 BS and constructed faulty not allow you achieve certain performances,220 volt have better performance than 120 and so on,machine should be function regardless of voltage input setup. Maximum Amps of output must be 20 not 4.3 and not 2.5,2nd failure in design involve digital rheostat control that increase or decrease voltage and amps,somehow those digital potentiometer linked with cooling fan capacitors and about 75% of machine related malfunction resolve failure of capacitors which resolve malfunctional fans or by playing with connection wires inside would switch between rheostats and fan operation.... Multiplaz 3500 have right idea and concept but failure in construction,if anyone study Multiplaz company is a splinter cell and start their own business in late 90's after split from original Russian company Plazzar which also broke to third branch Gorynich. First Multiplaz machines had transformers which was heavy and less accurate until introduction of IGBT took place,this also revolutionized new generation of welding machines and make them lighter and more compact like PC. Still Multiplaz didn't pioneer much in electronics,their sub contracting company located in China who assembles machines under Multiplaz not Chinese spec and that is why design failed,Chinese made their own variant and it proofed more stable than Multiplaz.... You need to understand parallel circuits and their plus and minus,you can't connect low consumption components on high performing or energy consuming components,this cost resistance and short circuit. This investigation of Multiplaz forced me design my own power supply,partially it completed while other half incomplete,current multiplier boards made but i didn't go beyond it and nothing been done further,torch about 85% completed but no further,I not have lot of time to engage all projects i got.... My plasma arc welder would only have single torch gun like original Plazzar have,you only switch anode cup's and flush water with alcohol solution or vise versa,inside torch there special moisture observing cloth wrapped over evaporator,moisture under heat turns into steam and steam breaks into hydrogen gas which result formation of plasma under high voltage. Plasma arc welding requires lot of voltage but much less amperage unlike arc/mig or tig welders,make it more easier to work with and eliminate requirement of shielding gas like argon or helium or oxygen with acetylene/map gas. The hotter the temperature the easier filling rod melts create enough fluidity and filling or welding joint,my torch variant allow to work 1 hour instead of few minutes,with conversion adapter and pressure regulator it also possible adapt torch for compressed air for cutting and helium gas for welding.... I also got completed aluminum heat sink where 2 fans would be located at the back,one fan is to flow in other flow out,cool air goes in hot air gets out allow linear cooling of power supply,2nd fan actuate through thermal regulating board along with thermistor located at end of torch to read temperature which activate 2nd cooling fan through contact relay.... it was took me about 2 long years to understand complete work of Multiplaz 3500 and over plasma arc welding technology and it's history and development....

I grew up working with my grandfather and his “old” tools. Not just lathes, but most older tools were built to last. I still have most f his tools that I inherited, and use regularly. Thanks for the videos!

Do you do mobile repairs? I got 5 broken m16 bolts I can’t get out of my tractor, I’m near Plant City, FL.

Would this work with a stainless steel bolt broken off in 1” thick aluminum plate? Or stainless in stainless?

22:33 Glad to see at the end of the video, you changed the earthing cable with a jumper to get it under the clamp (the cores are far too heavy for the motor load). In summary, apart from the crappy Chinese English on the instructions, and the replacement VFD (failed but without any analysis) the cheap VFD is a success. The good news is that three VFDs are still less than half the price of an equivalent US made VFD.

Hi! Where can I buy spare parts and cosumables? I have one , never used, still in box. Inherited that but scared to use because I am not welder and do not have spare consumables, Can you help me ? Ta

What type of sharpening stone do the GR and GL tools require? I'm a new Craftsman 12" lathe owner and am looking to upgrade from the stock lantern tool post I have now.

Thank you very much

Can't see what you are talking about in the column.

Very nice video mister.

Good video, I have a 100 series craftsman drill press and I want to make the same modifications where did you find the sheave (pulley) reduction assembly?

Oil pickup is on the right side of the bike. Killswitch on the side stand is to prevent oil starvation. It's for engine safety, not rider's.

What a great video, love the innovation!

the original solution you show at 1:08 with the zerk adaptor of a regular oil can. Did that work though, is it feasible? Or is it really that hard to pump and is better to choose this?

Love the D.C. motor swap!

Is that lead greats in the cup? I have 3 cans of it, made by Dutch boy, I still use it.

Finally somebody skillful showing how it needs to be done! Master

just wanted to say watching your video made slapping a new blade on my HF bandsaw and adjusting everything a breeze. I've had the thing for years and it always cut strange...never really delved into why and how to adjust it. Now I know. Thank you so much! :)

Curious... Why didn't you remove the upper threaded thrust collar from the spindle? It's held on with a 6-32 brass set screw. It is key to adjusting the quill on the spindle. Also, you did not remove the spring from the pinion shaft. Easy to r&r the roll pin.

Thanks

Thks for the video im very new to this trying to work out for my drill press thks again

Don, do you have any idea how I can keep my blade from slipping when I use the wax lubricant stick on it? It leaves a coating on the drive wheel of course, and eventually the blade will not cut, regardless how much I increase tension on the blade.

Thanks Don for making me aware that the bearing guide supports swivel, and make blade alignment possible. I've had my saw 30 years, and always assumed the horizontal bolt on each support arm held the arm in a predetermined, fixed position!

Thanks for the advice on blade tensioning. I think I discovered why I was cracking and breaking blades.

Saw blade guide bearings are on *eccentric* bolts. A cam is part of a rotating assembly which produces motion.

2:57 "There may have been a production shop out there that had one of these in the back." I've heard the Atlas lathe called "the lathe that won the war". So there's that.

Electronics have come a long way and China is doing a much, much better job in manufacturing - Many overpriced items like early VFD’s are simply extinct. Lenze makes great stuff, but not even remotely worth the price anymore and probably will be out of business soon.

Next day, Got it going thanks for your help.

Great video you awsered it all like a professional thank you

Hi, Thanks for the video, what about P26? Change from 50 to 60? Thanks

so all you need is a lathe and turning skills....who knew

plain speak....thank you, really helpful

I have the same lathe and converting over to dc drive also! What did you use for motor pulley? Did you keep the upper step pulley? Thanks john

Premo job !! Great skills!!

I have a craftsman benchtop 150(?) I bought inthe mid 80's and was barely used. 75.00 and was worth every penny and is still in excellent condition today!!

What size pin wrench do you have for it?

I picked up an old mill for a good price (its not in the best shape), but previous owner had been using grease where it should have been oil... Any tips? I was thinking about pumping a penetrating oil or alcohol in there every day for a while to see if I can get it all out...

So after 2 years of running that motor with that vfd, is it still working?

I bought a vfd for a regenerative blower I have but it won't work because the blower motor is wired in a wye configuration. These cheap vfds have to be used with delta wired motors.

I have a picscope and cheap piezo for vibration test on cars, you can do wonders with all this tools

What size Tip are you using I just put together a brand new set that I had laying around for 20 years and the tip is just junk I’ve kind of forgotten some of my sizes and numbers, this tip wouldn’t heat anything up that I had to cut, the first I was trying to heat up and cut was 3/16 steel just wouldn’t do anything I have to look at all this because it drove me nuts and I had to go to another method which took two hours cutting with a cut off wheel

Brilliant idea and superb instructions. Just picked up a 618 two days ago with tooling on original Craftsman workbench. The owner had been given it and didn't use it. But the best part is it was advertised as an Atlas 3950 so I was pleasantly surprised. Going to make this modification in a few weeks when I pick up my mill. Do you have a recommendation on the tool post brand? Thank You

what is the blue liquid on this bottle ? ( stan from Geneva Switzerland ❤)?

I want to do all those mods to my drill press, the same model as yours. Do you have a website with more detailed pictures?

This VFD is crap! Spent over 3 days trying to make it work and failed 🦧🤡

I had a lot of wobble in my upper wheel. To fix this, I wrapped heavy duty aluminum foil and contact cement around the tensioner slide bars. Between every 2 layers of foil, I brushed a little DAP contact cement, taking care not to have any cement get on the outside surface of the foil and then pushed the bar into the axle adjusting slide groove. I repeated this process until I had almost no wobble on either side individually, and NO wobble when both slider bars were wrapped and form fitted to 2.5mm I found that 2.5 mm is the sweet thickness on the sliders. The aluminum foil is only a MacGyver temporary quick fix. I did it to get through a project, and it's holding up surprisingly well. After I finish this current project, I'm going to have my cousin mill me up a couple of new sliders to 2.5mm uniform thickness. The biggest problems I find is that with these cheap saws, is the loose the tolerances make precision cutting iffy at best. UA-cam has a lot of great instructional videos on how to "tighten up" the slop and and make it a very serviceable and respectable machine. BTW, you're absolutely correct about not skimping on the blades. The OEM blade is junk. I put a Harbor Freight "top of the line" all purpose blade, and It made a big difference. I also bought a Starrett 99192-05-04-1/2 Intenss Bimetal Band Saw Blade, Powerband M42, 1/2-inch Width, 0.025-inch Thickness, 5 ft.-4-1/2-inch Welded Band Length, Pitch (TPI): 14. I haven't put it on the saw yet, and probably won't until I get my slide bars machined, but Starrett has been a major quality manufacturer for a very long time and I expect their highly rated blade to be among the best. Whatever other tolerances I can tighten up, I'll let you know.

Great video thanks
