Casting Day #27 - Bronze Pattern Maker's Hand Plane

- I got a few nice days in a row to do some casting, so got the sand ready and furnace out to pour the pattern maker's hand plane in bronze that Ive wanted to do. A few people wanted to see me ramming the sand mold up and casting the plane, so here it is.
Really well explained pros for maritime casting thank bro.
Thanks anthony, and yea, the maritime casting technique is counter intuitive at times, but works really well tbh.
Cool good poor Sometimes we lock out Thanks for the video
Thanks, and thanks for stopping in and watching it.
Looking forward for the machining part of this build. 👍
Yea, me too, I already filed the slot out and got that cleaned up, just need to sit it up on the mill to fly cut it now.
Turned out good!
Yea it did, Im defenitely thankful for that, lol.
Always nice when a perceived failure turns out to be a success.
Two things seem to be true about oil burners. The fuel needs to pass through a filter every time it is transferred (especially used oil) and gravity or aspiration feed to the burner is never consistent. It needs to be pumped at a metered rate if you want it to run without having to baby sit it.
I know many shy away from used oil, but with the current fuel prices you have to consider alternatives ...
Ive never really had much issue with my burner beyond needing to be cleaned once a year because the oil dries in it and gums it up over the winter. I think what happened was the burner was supposed to be silver soldered together and I didnt have the capabilites to do that at the time, so I just soft sodered it, and with the heat of doing iron, it just melted everything and fused itself up, ruining itself.
Does used oil wish thinning with lower viscosity fuels, e.g. Diesel fuel, or waste solvent?
I have a pattern for a screen-type filter, finished some time ago, but the Virus has caused issues…
@@dennisyoung4631 it works fine as is, as long as it's not too cold for the oil to flow.
Wow, that’s fantastic! Only you could fail successfully! I look forward to seeing this finished up.
lol, yea, I cant believe it actually turned out also, it was definitely a supprise when I opened the mold to dump it out, lol. I cant wait to get it done up so I can actually use it, lol.
Great Video Chirpy. I was surprised you attempted that first pour. It's refreshing to see the master struggle sometimes too lol. Really impressive molding.
lol, thanks, and yea, I was hoping I had enough metal in the crucible because with those crucibles, it's hard to tell how much metal is actually in them, so I figured I'd try it anyways. Im just glad that I got it in the end, was running out of time quickly before the weather was supposed to turn bad, lol.
Been looking forward to this one, that is such a cool pattern so seeing the molding was a treat. Haha, parts in the drag surviving a runout I've seen, but parts in the cope is new to me too. Lucky break, congrats! Castings look great.
lol, yea, I have no idea how that actually happened either, it was the first time Ive ever seen anything like that before, lol. The sprue and part of the runner was paper thin because the metal flowed out of the mold, and the only thing I can think of what happened was what I said in the video. The casting looks alot more patina'd in pics and on the camera, so in person, it looks much much better than what you guys see.
Looks great Chirpy, I really Like the color.
Thanks jammer, and yea, I do too. It really doesnt show up on camera the true color of the casting, but it does look really nice.
oh wow nice
Thanks emma.
Man, that came out nice! You got lucky with that one.
Thanks man, and yea, it really did turn out nice, which when the oxides are on the castings, it always looks rough till you hit it with a wire wheel, lol.
I couldn't believe the end result especially after seeing the blow out. Looking forward to the machining. Its going to look real nice in the bronze colour. Cheers Kevin
lol, yea, it really wasnt as bad as it looked when it first came out of the mold, and yea, it'll be interesting to see it machined up because it's kinda difficult to find a way to hold it, lol.
Man, just the patterns themselves are so amazing! Can’t wait to see the next step.
lol, thanks man, and I did a little cleanup of the throat of it off camera because I was getting impatient, but Ill try to get the rest on camera when I do it, lol.
WELL DONE, LOOKS NICE. REGARDS R.
Thanks, now to machine it up and make the plane irons for it.
Nice job and your patterns are really a piece of art talk later in the week at Emma’s
thanks paul, and see you later if I can catch the stream. Im usually on the discord tho.
Great job Chirps👍 gunna look very flashy when it's finished
Thanks bill
Your pattern is like a piece of art! Really nice work on that.
lol, thanks. I made that up over the winter out of some cedar planks from the skirting on a hot tub that we tore had gotten and that went to the dump, and some other scrap pieces of wood, so just reused every part that I can, lol. No use wasting wood, especially for the price of it anymore, lol.
I don't use those wooden wedge locators I use angle iron and a bolt so they cant separate like that but I think the main thing was the box was a little to small.
Ive tried angle iron and pins before, but they would bind/hang up every time I tried to use them, and I live in a high humidity area, so the pins and holes would rust themselves closed slightly, and you'd end up having to sand everything every time you go to use the flasks, so I just stick with the wedges.
I think it was honestly the bronze, I had plenty of room between the walls of the casting and the flask, but it still shot out, and a friend that gave me the bronze, he tried casting something a few days later and it did the exact same thing to him, and the part turned out also. I think the metal is just so fluid that once the mold gets full, the head pressure just pushes the metal betwen the parting line. I keep the flasks clampped, so it wasnt seperation that did it. The bronze alloy that we used, it was an odd superfluid silicon bronze, and I wanted to make sure it flowed into the part, so added some phos-copper shot too, and it may have just been too much.
Chirpy, That turned out really well, considering how scary it looked when the pour blew out the mold. I have never seen a crucible crack like that. Any idea on what caused it?
lol, yea, I thought for sure that mold was junk because there was alot of metal that squirted out the sides and onto the ground.
Ive had a few of those crucibles and they work fine for aluminum, but cant really handle the heat of the bronzes and it just cracked from the heat I think. I had brand new clay/graphite crucibles on hand ready to go, but the tongs were still sized to that fireclay crucible I had crack so tried to see if I could get by with it for that one pour, then I'd toss it and redo the tongs and such, but it didnt make it for that one pour. Those crucibles were cheap import ones and I had them and tried to use them up. I shouldnt have any more problems like that from now on since Ive switched to the high end salamander super crucibles now.
how lucky can you get? 👍
lol, yea, I was glad that it did fill even tho it has those crackling defects. After filing them, they're really only surface deep, so it really isnt any problem at all.
@@ChirpysTinkerings artistic licence 👍
@@Peter_Nottle lol, something like that.
Dumb question, what is the purpose of the graphite?
As always, really enjoy your videos and the great explanation of the hows and whys.
I should have waited a few seconds more and the answer is there!
@@Country_Bubba lol, yea, it works with brass/bronze alloys to help improve casting surface texture. Commonly, you see it mixed with an alcohol or flammable liquid and sprayed onto the sand mold after ramming it up using a paint sprayer, then lit on fire. The graphite helps improve surfave texture and burning alcohol dries out and hardens the sand to help strengthen the mold and reduce moisture/steam based casting defects. I dont really have any problems with moisture/steam based defects with bronzes because my sand can vent itself really well, so I just dust it with graphite only.
lol, thanks.
Have to be lucky some times mate..
lol, yea, which that was more than just luck, that was borderline miracle on that one, lol.
