As a machinist, from a safety standpoint I was screaming this whole video. Holding rotating equipment at thousands of RPMs is just plain egregious. Add to that the potential pinch point between your hand and the tool post makes this whole process unthinkable. Please, anyone watching this video, DO NOT replicate the actions this guy took here. The fact that you survived is the truly amazing thing here. This process should ONLY be done with properly rigid holders. AT THE VERY LEAST, use a Jacobs chuck in the tailstock, NEVER your hand. I cannot stress enough how unsafe and terrifying the actions you took are to me. Never should hands be this close to rotating equipment.

I have seen another guy do some very tight tolerance stuff with this process and I can not understand why anyone would do a different process like PLA etc.
@Wrighmachining11 күн бұрын
I can see how you would say that . Kelly cofield makes some amazing stuff. The two are very similar with a few strengths for each but sharing many . i have not tryed lost pla but done lost. wax, pla seems like it has the ability to be printed and will hold its form way better . I have found that lost foam will distort and has spacific direction it has to be placed in . What i love about it is that you can make it with very basic tools and turn it into a metal part quickly.

So the transformer is a step down transformer, but you are using it as a step up transformer? That is not recommended, one reason is the primary windings are usually wired close to the core to obtain opimum coupling, now you are winding secondary there, this will cause higher losses-in the form of heat, I would get a thermal imaging camera to make sure you are not exceeding the 150deg on your specification there. Ideally you would use a phase convertor that ALSO steps up the voltage, if such an animal exists?
@Wrighmachining29 күн бұрын
Step-down transformers are occasionally used as a step-up transformer by “reverse feeding” or “back feeding” the transformer. Reverse feeding is simply a matter of having the power supply enter at the low voltage windings. I have not noticed it hot at all . Infact it is way larger than i actualy need .
@engjdsАй бұрын
What is the power output or rms current of the phase convertor?
@Wrighmachining23 күн бұрын
Botb transformers are 30 kva . In saying this that is massive compared to what is required of them . The motor is also way over sized for the lathe but i buipd things to expand them . Later if i plan to get a bigger machine ( loke i have the room , lol ) i can do that .

polystyrene is a polimer styrophoam is made out of, not the end product so both low density expanded styrophoam and uniform extruded foam insolation panels are both made out of the same material polistyrene, the only difference is that low density packing material is expanded from plastic pelled by overheated steam while uniform insolation foam is directly injected into a mold in liquid foam state ps is only visable on styrophoam product made out of pellets for recycling, and many supermarket food trays have the same marking while being the same kind of foam as your insolation panels you can also buy polystyrene sheets for vacum forming or injection pellets or 3d printer filement in solid state . it is also part of abs and hips plastic composition anyway nice project you making thre

Thos has to be one of the best comments i have ever had !! Thank you for taking the time to write it , it is very insightful. You have sent me down the rabit hole now of steam and expanding the pellets . Sounds dangerous i know ,lol . Dont worry it will be a while before i wade through a zillion projects and get to this and i will be very carfule . Lots of people ask about expanded foam but its not usable i have heard. but the pellets and steam would work . This almost gets into a large industral set up of injection molding and casting and i wonder if that process would be any faster in the long run than making each part manualy or cnc?
@kokodin5895Ай бұрын
@@Wrighmachining well it is high flow production process, pellet contain a tiny bit of carbohydron that expand from the temperature while plastic is getting soft steam is used as heat source because both superheated styrene and aditive are basicaly as flamable as gasoline so it has to be injected to sealed container with no excess oxygen but also vented to evacuate excess gases that can be used as a fuel for steam boiler. i wouldn't try that at home pellets thown into fire explode so it is to be stored safely too

I see that this video is about 1 -1/2 years old but I still thought it was worth mentioning that your level is .0002" (2 ten thousandths) between graduated marks on the vial, not .001". The vial was made to indicate .0002 over a 10" span, in other words, the distance between the marks on the vial represent .0002" (2 ten thousandths) rise over a 10" span. Very sensitive level for sure, mine is .0005"/10" (2.5 times less sensitive than a .0002"/10" but still plenty good enough for the job).

Technically what you have is a furnace and not a foundry. The problem is some newbies did early videos years ago and misused the term and not it is quite often used. A foundry is a place where metal casting is done. As far as the heavy weight of your loaded box. Why not two boxes? Less awkward and less weight. Reserve the big box for the jobs that need it. I found your channel yesterday. Its nice to see useful stuff being cast along with decorative items.

Could you build your box without a bottom, stick it in your job box, fill it with sand, then do your pour directly into your job box? That way you can just lift the box off when you are done. Any overflow would be into the sand in the job box. It means lifting the molten metal higher so that might be a problem.
