An aluminum jack isn't completely useless, as compared to a steel one, it's only about half as useful when you look at its mechanical properties. Thank you for all that you do in producing some of the finest edutainment on RUclips.
52 years ago I got into casting jewelry... mostly lost wax but also other pattern and mold medias. I have been fascinated by taking metals to liquid, and back to solid in a new form ever since. I enjoy these casting videos immensely. Its been years since I did any casting, and may never again, so youtube is where I get to enjoy seeing it done. So, Lyle, more please👍.
Thanks Mr Pete. I absorb this information like a sponge, and I like it! Two things made me think of my dad. First I said that's just like the pocket knife my dad carried. Then you showed Deft... That was his go to varnish. He restored antique furniture.
Glad to see you back, Sir. My RUclips shop teacher. MrPete, you must have been a heeluva teacher. The teacher that all the others sent their incorrigibles to (in those days the MALE incorrigibles). You even inspire me and I am old and cynical. Love ya, MrPete.
I like the wooden pattern, some of us old guys will never use 3d printing. Keep up the good work. Be sure to let us see Henry with his new vise, and work bench!
Another great video Mr Pete, thanks very much. I particularly liked the speeded up clip of the aluminium cooling, shows the whole shrinkage thing very well. Cheers, Alan.
immensely satisfyingly to watch a project come to fruition when you start from your own castings, instead of a chunk of mass produced stock. inspiring .
G’day Lyle another excellent video. The video of the shrinkage was a nice touch, I have poured many castings, witnessed the results but never sat there to watch it happen, thanks. Cheers Peter
Love those little machinist jacks! I like how you had the students cut a different pitch on the threads so they couldn't copy each other's setup, nice teacher trick, Tubalcain, you always have great stories. CAD Cardboard Aided Drawing and WAD Wood Aided Drawing lol love it ! Really enjoy the discussion on the split pattern making.
LOVE YOUR VIDEOS!!!! i'm a 1948 model and can relate to your comments!! For what it's worth, I use brown paper (grocery bags) when i glue two halves of wood together to turn on the lathe. They separate easily and don't come apart while turning. For clean up i use a belt sander. Not sure if that is precise enough for making a two part pattern.
What is it about that bell curved base flare? Man, that is so pleasing to my eye. I like where this is going. In college physics, our professor let us 'pick' our grade at the first of the semester. He put out the C - level, B-level and A - level requirements. It was a demanding school, so earning a B there was like a 7.0 at a state school, no grading curve. I took the B-level route, but did the A-level requirements as time permitted. I got my B+. You reminded me of that with the "better students" section of the video. I appreciate that. If I'm rushed, I always come back to finish up after the day has finished with me.
I am 12 and want to be a machinist but all I have is a 1974 Rockwell drill press that was my great grand father and a wood lathe. I have a neighbor that has 6 CNC machines and gives me aluminum plates, bar, angles, and round stock and I cut it with a hacksaw from the 60s and files from the 60s and am trying to find a lathe or mill and my neighbor knows someone who is selling a great working shape for $800 because he just wants it out so I’m saving up by trying to sell my turnings online. Love your videos kept them up!
mrpete222 my uncle has a Bridgeport and a big lathe but he lives 3 hours away and I turned some brass and that is all of the experience I have but know a lot because of your videos mr. Pete and I watch the extra credit!
I worked as a maintenance technician in my youth alongside a seasoned shade tree technician. He could barely read and was limited in that he had almost no electrical skills. But he owned some tools that I envied. He owned two Armstrong planer jacks like the one you showed in the catalog and the same size as your Simplex jack. I borrowed those jacks as often that he allowed me. Now retired and owning thousands of tools I still have very few screw jacks, and most of them are shop made. I am still looking to add Armstrong jacks to my collection, but really have almost no need for them now. Armstrong made superior tools in their day. I own over 240 clamps and treasure my Armstrong clamps more than any other brand.
The close-up of the metal feeding into the shrinking casting was a very good visual. The cad designing is not an imposition but it is educational to see wood pattern making anyway.
Once again your knowledge is notable. I wish I was younger and had access to the things you have. I would be in hog heaven. Thank you for your time and expert working skills.
I think your father must be very proud of the educator you have become! How many teachers will ever affect as many students as you have? I will never attempt most of what you show yet I watch the videos over and over. I would love to see you build a multi cylinder steam engine. It would also be fun to build some sort of dyno to see how much power they can generate.
Extra credit student here: I agree that the 3D CAD patterns are marvelous, but I think it is important to understand the rudimentary processes of pattern making. People don't think anymore, they just let the computer do everything for them. Thanks for the WAD lesson.
New Mr.Pete TLA...WAD to add to wikipedia. 😊 Thanks for explaining the pattern splitting setup, common sense sometimes needs a kick start. Watching foundry casting never seems to get old. Would like to try it someday, but man one almost needs a seperate shop for all that gear. Very enjoyable...looking forward to the next episode...
I’ve got to find someone around here to do some casting for me when in high school I pretty much had the run of the woods/metals/small engine shop in my junior and senior years and was in there for the majority of my days and I discovered a lot of the old metal casting stuff and lathe tools but of course the teacher didn’t know how to use any of it as any foundry or machining was gone out before he went through school here so with not really knowing anything we took some of the old black sand and some forms and cast a few things in I believe Babbitt material as we found quite a few ingots of it. A fond memory of discovery.
If only you were my CDT teacher (metal work) in the 80s in the uk considerable more would have sunk in to my brain .Thanks and keep the good work up and I might learn something useful.
Always look forward to your uploads. 1903 Springfield barrel tenons had square threads, my dad used to curse them whenever he built a custom rifle on one of those actions..but he did it nonetheless! Thanks, Mr. Pete! :-)
I love my old tools. I have a Speedex Wire Stripper I bought for a dollar at a swap meet when I was 13. Have had it for 55 years now. Still the best stripper I use.
Bravo! You are right, as usual. Sports programs are the "sacred cows" of American education. Why does the football team get the expensive new weight room while the physics department goes without desired equipment? After all, those "student athletes" could simply get the same expensive weight training facilities (as well as complete their educations) later on in state prison. Your discussion of pattern-making is the most interesting part. Artistry is involved in this. You should consider providing even more detail. I hung around for the extra credit. It's easy to succeed in school. "Just show up and pay attention". My father told me this back in the day.
Yes Mr. Pete222 that pine block of wood you first used was pretty ruff. tho it could of been saved with a little sand paper. BUt Maple was a much better choice. And I always stay for extra credit. I day dreamed in class too much. So I needed it. I even paused your video to go look something upon the web you were talking about! I even made a pair of those Jack screws in my Machine Tool class in tech. school. It is easy to make the ACME. thread. just hand grind a HHS cutter to the size tooth pitch. you need. I did it as a student. I know you can do it.
Henry is a very lucky boy to have a woodworking vice made for him by his Grandfather Mr Pete and he will also be able to watch the videos on the making of his vice for many years to come.
I believe the secret is resin. It flows around the hot metal making for smoother pourings. It tends to bind and make sandstone afterwards - but that can be broken.
I have read somewhere the catalyst is essentially methanol, the petrobond powder is a organo clay called bentone 34 (not the same as bentonite) for those who are interested...
Mr. Pete, I saw your knife and wondered if you have ever done a video on pocket knives? I always used to carry Case knives, do you have a preferred brand, size, etc? Great videos, keep up the great work. Many thousands of people are relearning machine shop because of you! Stay safe.
Just for the sake of conversation, could you have done the casting as a deep draw pattern with a riser to account for shrinkage? Always love your videos! Informative and fun to watch.
Mr Pete I'm not a computer fan I guess because I'm old like you but I would rather make a mold of wood than have a computer do it for me maybe I'm old fashion but at least it's something that I made with my own too hands much more gratifying thanks for making taking the time to make your videos for us
Hi also from Melbourne, Australia - a bracing cold and frosty night outside. On front of the fire, watching Mr Pete. Even one of the two dogs at my feet taking some interest in the video. Other dog clearly has no interest in machine shop work, then again she is a Labrador.
Hi Mr. Pete. I asked you the other day if you had to buy one, what would be 1st. A mill or lathe? You said a lathe. So I followed your advice and because this is all new to me and I think most of the things I'd like to make are small I bought a mini lathe. After I ordered it the guy said, anything else I can get for you? I said yes. I'll take a mini mill also with some tooling for each. So you see I did take your advice and got a lathe 1st😁. Now I'm looking out at the driveway for a truck. I can't wait. This a a retirement gift to myself from the wife
I swear. You say the same things about your teaching days that my metal working instructor says about machine tool acquisitions. He tells me how the new female principal would enter his classroom back in the day and dream of selling off all that equipment and turn the space into a pottery class. When the new high school was built guess what they left out of the mix? It's a shame how the powers that be are so ignorant. This country is in a pickle now because of it. Skilled hands simply cannot be found anymore. As always, good work! Stay healthy and keep the videos coming!
There you go again, the epitome of perfection. Sure wish you were my neighbor! Probably best you aren't cause I'd never go home! Come on with number two!
Elimination of “shop” classes is one of the biggest mistakes ever made in this country’s educational system. Beyond teaching young men and women how to use tools, above all else, it taught them how to solve problems, use their imagination and to take an idea and follow it through. So very sad 👍😊 Thanks Mr Pete for keeping the dream alive!
very smooth finish for a casting! I guess it's part sifting the magic Petrabond sand and part that the part was sealed well. I love watching your vids. what to do when you run out of Petrabond or do you have enough for life? haha
I don't see anything wrong with developing knowledge and then using it solve problems. Yes the idea might not be original. But there a high chance over the years you developed something that combined those years of learning. Into something unique/original. But I am sure you've influenced more people that most get a chance too. Just from your years at a shop teacher. Even before your youtube channel.
Dear Mr Pete, teacher, sir, I have not watched this video yet but will. I just wanted to say that I have been thinking about machine jacks lately because though I do not have any, I want to make some type of Screw adjustment legs for my Chinese 7x10 mini lathe. The lathe has a bit of twist in the bed that can be gotten out by shimming and bolting down the lathe. It also needs to be set up about 3 inches higher for my needs. I had some big rod couplers over the long hold down screws which I then shimmed to take the twist out to take the taper out of my turnings. But I have since taken that apart and am rebuilding a lot of stuff and am trying to figure out a method of having adjustable legs 3" high that attach so they can draw down or up any of the four corners with the turning of a screw ...then locking down. So machine jacks are in my mind trying to figure out how to rig something like them as legs. Maybe you could offer some insight...Thanks.(Why am I tempted to call you "Doc"? Maybe it's because I see you as the wise old professor...)
we get our sand from lake mi washed and ryied also yuma mi cast foundry cmi cast parts we make exshaust manifolds and use to make the twin i beam on ford trucks
I'm primarily a woodworker, but nonetheless really enjoy your videos. Do you think you could make a video on turning wood on a metal lathe? I think machinists might be especially interested in this if they don't have access to a wood turning lathe.
5:16...so, if you are using "close-grained' wood to make the pattern- does that mean that you are using "tight w.a.d." casting?!! (get it? get it? get it? snucker-snucker-snucker!!!)
Real handy size for like a 12x18" granite 3 point level. If i start with casting I think I'll start with somthing I can melt with the little torch A thimble size crucible too. Small stuff can be real useful also. I have two one inch shank bolts that next time i set up to thread I'm going to thread 5/8 10 acme those and a tool makers vise bolted to a right angle plate with a foreedom grinder and a v block allow for hight adjustment relative to a 5c collet index for split pointing drills a homade collar at the back with a 3" 75 mm pin set the angle with the index pin on the vrenier .lock the collar pull the pin out of the vernier and now the 5c spindle slides in and out on the 3" 75 mm pin and the angle you set the spindle to by locking your homade lock collar will slide in and out on that set angle machinest jacks are just sooo meat and potato's good stuff again big THANKS
I would of thought that if you made the part as a single piece on the lathe. Then taken it to the bandsaw and cut it down the middle to create your split. Then if needed add paper or some other material to make up for the kerf the blade. you would be golden. Also I would be more than happy in the future, to help you with 3d models or printing if needed. Your sharing your knowledge and experience. The least I can do is share my skills and knowledge in return.
Thank you, I may need the help. I have cut through patterns like you described. But only when the final dimensions and appearance are not that critical. You really can’t restore the geometry
@@markthompson4885 I'm just trying to figure out if it's better to let it totally cool in the mold or maybe it doesnt matter. Personally I would be impatient and want to know as soon as possible if the casting was acceptable or know if i needed to start over while the furnace is still hot.
@@andrewevans1658 I'm like you I would be too. I've done a lot of casting for lead bullets aluminum acts very simular. I would give the aluminum at least 30 minutes to solidify. Of course it will still be very hot.
For the 'extra credit', could you have rigged up a pantograph type jig to copy the original? Adjustment of the mid arm length could be tinkered with to produce a slightly larger pattern to possibly compensate for the shrinkage factor, Any thoughts on this idea?
I turn projects out of glued up wood at times. Apply glue to both sides and put a piece of newspaper in between the pieces. It will hold together on the lathe. A tap with a chisel and mallet parts them nicely. Frank
I see I'm not the only one awake before the sun. Yeah, the videos are enjoyable. Have you made any cast iron casting? You know what? I'd say these tools you have; came in handy over the years and more so these days of Covid19 (2020's version of Stalag 13) virtual lock down by some local mindless wonders in office. Have a nice day.
Mr pete , what is your aluminium source? Do you use old engine blocks or ???? 4xxx or 6xxx aluminium ?? Please explain us,so we learn a little bit more !
An aluminum jack isn't completely useless, as compared to a steel one, it's only about half as useful when you look at its mechanical properties. Thank you for all that you do in producing some of the finest edutainment on RUclips.

Thank you very much, I’m glad you like the videos. Sounds like you had fun casting in the olden days
Thanks Mr Pete. I absorb this information like a sponge, and I like it!
Two things made me think of my dad. First I said that's just like the pocket knife my dad carried. Then you showed Deft... That was his go to varnish. He restored antique furniture.

LOVE YOUR VIDEOS!!!! i'm a 1948 model and can relate to your comments!! For what it's worth, I use brown paper (grocery bags) when i glue two halves of wood together to turn on the lathe. They separate easily and don't come apart while turning. For clean up i use a belt sander. Not sure if that is precise enough for making a two part pattern.
That is a good suggestion, to use brown bags. It’s a little thicker than white paper
What is it about that bell curved base flare? Man, that is so pleasing to my eye. I like where this is going.

Thanks
Petrobond catalyst is propylene carbonate by the way. Methyl hydrate or a high percentage isopropyl alcohol can be used instead in a pinch.
This takes me back to 1971 and high school. thank you

Thanks for the great informative video. Always enjoy your foundry vids👌
Hello Clarke
very smooth finish for a casting! I guess it's part sifting the magic Petrabond sand and part that the part was sealed well. I love watching your vids. what to do when you run out of Petrabond or do you have enough for life? haha
I have 500 pounds of it in the attic. I will never run out
I don't see anything wrong with developing knowledge and then using it solve problems. Yes the idea might not be original. But there a high chance over the years you developed something that combined those years of learning. Into something unique/original. But I am sure you've influenced more people that most get a chance too. Just from your years at a shop teacher. Even before your youtube channel.
Thank you very much for the kind and encouraging comment
You're a jack of all trades!
lol
Dear Mr Pete, teacher, sir, I have not watched this video yet but will. I just wanted to say that I have been thinking about machine jacks lately because though I do not have any, I want to make some type of Screw adjustment legs for my Chinese 7x10 mini lathe. The lathe has a bit of twist in the bed that can be gotten out by shimming and bolting down the lathe. It also needs to be set up about 3 inches higher for my needs. I had some big rod couplers over the long hold down screws which I then shimmed to take the twist out to take the taper out of my turnings. But I have since taken that apart and am rebuilding a lot of stuff and am trying to figure out a method of having adjustable legs 3" high that attach so they can draw down or up any of the four corners with the turning of a screw ...then locking down. So machine jacks are in my mind trying to figure out how to rig something like them as legs. Maybe you could offer some insight...Thanks.(Why am I tempted to call you "Doc"? Maybe it's because I see you as the wise old professor...)
Maybe this video will help you
we get our sand from lake mi washed and ryied also yuma mi cast foundry cmi cast parts we make exshaust manifolds and use to make the twin i beam on ford trucks
👍👍
Thanks MrPete, great video!
You can still get the Petrobond sand and components from Midwest Technology Products. They also have the Mini Mite sand muller for $4,000.00.
Thanks
My tool and die friend is appalled whenever he sees sawdust on my South Bend lathe. Glad to see some sawdust at the 14:22 mark.
Yes, I thought more people would criticize that. I don’t believe it hurts of thing. But it is messy
G'day from southern Tasmania.
Hello from the northern hemisphere
I'm primarily a woodworker, but nonetheless really enjoy your videos.
Do you think you could make a video on turning wood on a metal lathe? I think machinists might be especially interested in this if they don't have access to a wood turning lathe.
👍
Very Interesting. I am familiar with the Lost Wax process for Cast steel work.
5:16...so, if you are using "close-grained' wood to make the pattern- does that mean that you are using "tight w.a.d." casting?!!
(get it? get it? get it? snucker-snucker-snucker!!!)
lol
Pete, could you pour an aluminum base with a steel insert? That would
improve the strength by at least twice.
I am working on a video where I make more Jack’s. They will have a steel insert with the thread
Still here mate 😉
👍
Real handy size for like a 12x18" granite 3 point level. If i start with casting I think I'll start with somthing I can melt with the little torch A thimble size crucible too. Small stuff can be real useful also. I have two one inch shank bolts that next time i set up to thread I'm going to thread 5/8 10 acme those and a tool makers vise bolted to a right angle plate with a foreedom grinder and a v block allow for hight adjustment relative to a 5c collet index for split pointing drills a homade collar at the back with a 3" 75 mm pin set the angle with the index pin on the vrenier .lock the collar pull the pin out of the vernier and now the 5c spindle slides in and out on the 3" 75 mm pin and the angle you set the spindle to by locking your homade lock collar will slide in and out on that set angle machinest jacks are just sooo meat and potato's good stuff again big THANKS
👍👍
I like the rant on school spending..mine is why post only athlete championships and not academics outside the schools.
Yes
Great looking casings. Shrinkage is always a problem.
Yes
Like your videos! BR Anders from Sweden
Thanks
I would of thought that if you made the part as a single piece on the lathe. Then taken it to the bandsaw and cut it down the middle to create your split. Then if needed add paper or some other material to make up for the kerf the blade. you would be golden.
Also I would be more than happy in the future, to help you with 3d models or printing if needed. Your sharing your knowledge and experience. The least I can do is share my skills and knowledge in return.
Thank you, I may need the help. I have cut through patterns like you described. But only when the final dimensions and appearance are not that critical. You really can’t restore the geometry
Awsome project!!!! Does the rate of cool down of the casting affect the overall metallurgy/grain structure/hardness/elasticity of the casting?
Yes it does.Depending on the Alloy. But I believe Mr. Pete is using almost pure Aluminum. His casting are the softest of all the aluminums. .
@@markthompson4885 I'm just trying to figure out if it's better to let it totally cool in the mold or maybe it doesnt matter. Personally I would be impatient and want to know as soon as possible if the casting was acceptable or know if i needed to start over while the furnace is still hot.
@@andrewevans1658 I'm like you I would be too. I've done a lot of casting for lead bullets aluminum acts very simular. I would give the aluminum at least 30 minutes to solidify. Of course it will still be very hot.
For the 'extra credit', could you have rigged up a pantograph type jig to copy the original? Adjustment of the mid arm length could be tinkered with to produce a slightly larger pattern to possibly compensate for the shrinkage factor, Any thoughts on this idea?
Yes, but I was still be working on the pantagraph trying to figure it out
I turn projects out of glued up wood at times. Apply glue to both sides and put a piece of newspaper in between the pieces. It will hold together on the lathe. A tap with a chisel and mallet parts them nicely.

That bag of fertilizer are you going to need it? LOL. Again great video, gives me an excuse not to clean house.
another great one. thank you
Thank you
I see I'm not the only one awake before the sun. Yeah, the videos are enjoyable. Have you made any cast iron casting? You know what? I'd say these tools you have; came in handy over the years and more so these days of Covid19 (2020's version of Stalag 13) virtual lock down by some local mindless wonders in office. Have a nice day.
Be thankful they have the brains to try to contain the China Virus
Yes
Great video thanks.
The jack at 3:49 that you think may be home made looks just like a Starrett jack that I have. They also come with 2 risers.

Mr pete , what is your aluminium source?
Do you use old engine blocks or ????
4xxx or 6xxx aluminium ??
Please explain us,so we learn a little bit more !
Automobile pistons are by far the best source
@@mrpete222 Thank you mr Pete,learned already.
Thanks again for a very informative video.
👍
Hey tubal.i agree they are beautiful but the missus moans when I put lumps of steel on the mantelpiece
Let her moan, that’s what we do
It was shrinkage Isn't that what George Costanza said?
