Metal Casting at Home Part 64. Casting and Machining a Toothed Pulley.

[@chrislangtiw6395]

I love watching your videos. They take me back to my days in foundry and machine shop back in school, and remember back when my dad was an apprentice machinist. I still get excited whenever I'm in a shop and wish I had one of my own to work with (along with the time to tinker).

[@rogerd4559]

this guy's a pro. Since computers this tecnology is practically lost Good to see someone reviving casting

[@jpeterman6178]

I agree.

[@Juklitz282]

Is not, that´s a belief. There´s plenty of manual engineering work, it´s not effective to have CNC, water, lasers for smaller production, tool maintenance etc. It´s not that visible, but still exists.

[@ianmoone2359]

Yep, some wiz kid would 3D print it with sintered metal while anyone else was still making the timber moulds & machine the plastic blank, and mixing green sand. That’s why these technologies are dying art forms. It is good to see the knowledge being preserved for posterity. Yes you could cast it or you could have bought a short piece of 6 or 7 inch alluminium round bar stock & just turned it in the lathe & then milled the teeth. I have to say I do enjoy watching this all the same, very satisfying.

[@nodrogawson963]

Nice accurate casting, not far off true even before you machined it. Like the way you use the chuck to mark the 3 fixing holes. Always seem to pick up something new every time I watch your videos. Thanks again for sharing, your videos are very much appreciated.

[@headstocktailstock]

Like the ball bearings on the end of a rod to smooth out the sand,I've been using those for nearly 45 yrs when built my first foundry with my late Dad,[burnt a few out since then!] there was no internet then to show you how, I just had B Terry Aspin's book "foundrywork for the amateur" ,having said that I have picked up one or two useful ideas from yourself & others ,never too old to learn, I use mainly petrobond or co2 for plaques with fine letters & mansfield red for anything else,[of course it's not red anymore after 100s of melts!!, thanks for the stovefan castings,[nice castings] Graham.

[@myfordboy]

I taught myself from the same book. No internet when i started casting. Terry Aspins son left a comment on here this week.

[@headstocktailstock]

Thanks for the reply,didn't know he had a son, his stuffs still relevant today,allthough I have a small propane furnace I still do nearly all my casting using coke & a bouncy castle blower, mainly 'cos we've always got a couple of tons in for the rayburn I like your waste oil burner, will have to make one it's a bit easier than coke Regards Graham.@@myfordboy

[@ctjctj2]

@myfordboy, most stepper motors have a fixed number of steps. For example 200 steps per revolution. When you are designing your gear rations you might need to take that into account in your sketch. For example, my hobby CNC router has resolution issues for long moves because the controller wants an integer number of steps per inch and the ratios for the gearing is not an integer. So over the course of about 10 inches the position is wrong by a few 1/1000s. This might not be an issue for what you are doing but if you are going to be using this for gear cutting you need to be able to come back to exactly the same point. Good luck to you, you do some amazing things. -Chris P.S. I switched to alloy rims for my source of aluminum and it makes a huge difference in the quality of my castings thanks for suggesting it.

[@sojournsojourntraveler1203]

He went to a great deal more work for the aluminum casting. Never gets into the safety aspects of molten aluminum eater. I cast round stock aluminum and use as needed for different projects. a great cutoff tool is a old finishing wood saw as the fine teeth do not get clogged but they are small enough to not grab too much aluminum.

[@andrewwilson8317]

Nice work. Would I be far wrong if I said it looks very much like you getting ready to cut cam lobes and profiles? The stepper motor indexing the spindexer is exactly how I did it! I used a digital vernier slide for the vertical movements and cut depths.

[@myfordboy]

I don't have that use in mind but thanks for the suggestion. I have a little delve into CNC coming soon.

[@andrewwilson8317]

myfordboy looking forward to that. Going to be very interesting.

[@garthn2561]

CNC varies from very simple to extremely difficult. I CNCed my Myford lathe, can't dream of going back to manual. But that was fairly simple programming (although threading was a bit of a challenge). LinuxCNC or Mach3 are already very capable, but generating Gcode for 3D milling is pretty complex. I was waiting for someone to show a DIY stepper controlled indexer - brilliant.

Would you please do a match plate style pattern demonstration; the casting shop we use at work operates with that style for efficiency.

[@myfordboy]

I don't like the matchplate method. I ram the sand quite hard and like to remove the pattern carefully to avoid damaging the mould.

[@lucianoguerra9013]

I like them to, but sometimes they go over my head as to why go through the trouble. It's nice work but the use escapes me r I just don't care. I was just here for the first part the rest just boded me. I liked the cutting of the aluminum bit the teeth an the rest not so much. Thank You Loader. I'm glad you understand it.

You're good at what you do. My question focuses on the aluminum you poured. How do you determine the aluminum has the proper mixture to hold up to the stress and balance a pulley needs to have?

[@myfordboy]

Using metal that has been cast before gives good results.

Interesting videos! I just tried to cast a large 10" diameter X 10" tall planter pot out of bronze. I used the Lost Wax and Cavity Pour techniques, filling the inside of the planter with plaster of paris, then inverting the mold to fill the outside of the planter. This was all done in a galvanized 6 gallon bucket. The plaster, filled to the top, was allowed to cure for about 1 month. The wax was then melted out. During the bronze pour there was an incredible amount of boiling, bubbleing, smoking and popping. Almost to the point I where I almost aborted the pour. After de-molding the planter, the results were catostrophic! The planter had massive pock marks, gapping holes and look like it had risen from the ashes of Chernobyl! I wonder if this was caused by the reaction with the plaster, or perhaps the plaster couldn't breathe/out gas properly? Any analysis or recomendations would be awesome! Also, what brand of pouring tongs/shank are you using in Part 64? Thanks for your help!

[@myfordboy]

If it is just regular plaster it's going to crack. I have done similar but used a proper investment plaster like this product. www.artisanfoundry.co.uk/product_info.php?products_id=97 If there was the boiling as you describe it was not dry enough. The plaster I mentioned needs probably 5 hours at 650C to dry it out before use.

[@policedog4030]

Viva England and it's Master Crafters! If only I'd have just had the benefit of witnessing this kind of well-earned competence as a 3rd Grader.. Bodes well for the future because today's young 'uns can see this with a click.One observation (that well may not be correct - but just food for thought) - if you are planning to drive the indexer a long time... (more than two minutes) Those little power components on the Arduino are very precise and accurate and will work perfectly of course as you demonstrate but I suspect maybe not if you try too many repeated operations. I am not an expert but just going by visuals.. For example look at automotive 12 volt ECUs and look how they size the chips in the power section. The Mosfets attached to aluminum heat sinks with heat conducting grease..I Don't know the actual specs just what they look like as far as size. A little beefier to handle the heat would perhaps be better. Hopefully someone who knows will chime in.Very sophisticated work you demonstrate and it is inspiring.

[@merrickray]

i dont have an indexing head. I do have a chinese cnc machine that is great with aluminium.. and a chinese 8x24 lathe I would have used to face the back of the pully then put it on the cnc machine to profile the teeth by drill milling the pattern, then cnc machined the centre hole and outer diameter too. back in the lathe to finish the other face etc. It works, I have made many bicycle chain sprockets.. even in steel (but thats pushing the cnc. 6050). The trouble with the chinese cnc is the cross bars are just only 16mm and 100mm apart. 500mm long and they bend under load. The cutter can twist the rails 1mm with 20kg force. if they had used 20mm shafts that would be about 100kg and a 25mm shaft about 400kg.. I will modify it one day.
