I had the same issue of gates freezing off when there were more of them than I was used to, and also solved it with a slightly bigger sprue and runner so that the gates' flow would not be so slow once divided off the runner. Worked for me too... Mostly. Nice ornaments! For a job like this, a snap flask would be quite handy.

Oh sure after that buy of a lifetime, throw the snap flask thing in my face 😄😄 How many did you end up with?😄 I'm kinda sticking with venting on this one. Maybe I rammed the sand in the cope harder given there was no give to it like I would normally have with ramming on top of a sand filled drag. I don't know.

@@swdweeb getting pins to line up well is always a pain, but I have found attaching the pins to drilled wooden blocks lets you get away with having not quite perfect alignment that may cause binding using metal brackets. I'm still waiting for Martin to finish his flask series so I can see how he gets his pins to slide so well and maybe start using my cast brackets again. The trouble with having many flasks is finding space for them all!

I had a random thought... How about casting some bits in brass (like the star), then placing the brass part in a new mould and pouring the rest in aluminium. Polish it up for a bi-colour ornament.

Hey Perry. Nice to see you being still in action. Love your videos! !!!Big heart!!! 6min into the video. I would guess: By having alot exit point dimensions from small to big (the metal line into the molds), the metal slows down that much so that it cools down too fast and is not reaching every mold properly. Dont nail me on it but wasnt there a rule saying when splitting up from the main line the new ones should be only half the size max of the original one? Venting helps to reduce the factor of slowing down the liquid metal by reducing the force of compressed air (wall-like). More small feeders always help. ;) Maybe Im wrong here. Wish you and your family happy holidays, health and a wonderfull christmas. Cya around, hope next year too. ;)
@swdweeb
@swdweeb 3 года назад
Han don't make me yell at you 😄😄 I know there is a rule on spitting the runner. I've seen plenty of examples of that in the books. Adjusting the size of the gate is the easiest way to control the speed of the metal entering the mold. Thanks, I have every intention of being around next year

My first thought at the beginning of the video was venting. Also, you stated that the volume increase across you in-gates were 4x your runner. I am curious when you increased the volume of the runner with the wood slats what then was the ratio? Also, I haven't been watching your channel long enough to know how do you take your pour temp? Merry Christmas!!!! I really enjoy your channel. It takes the "backyard" foundry and applies proper industry and calculated technique very well.
@swdweeb
@swdweeb 3 года назад
Its funny, I didn't mention it in the video but I tried to vent the parts with the original sprue. You can see them in the pictures starting around 2:15. That was what led me to the volume thought. The big difference in the vents at the beginning and the vents at the end was the clear path to the outside of the mold. I mentioned my thermometer/thermocouple in my previous video regarding the tools you'll need to make ingots. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-fFADzuaCtQs.html I have links to the parts in description of that video.

@swdweeb
@swdweeb 3 года назад
Possibly. I might have rammed the cope harder since it was on a board and not on sand (drag). Kevin Watson also had a theory that is plausible. He thought the second mold didnt mate well due to the evidence of flash. That might have let the gas out of that mold and might be why it didnt need the vents

Cold sand. I maybe wrong but I keep my sand in an unheated shop and the 70 degree difference between inside where I pour and the outside shed where the sand is, cannot be compensated by increasing the metal temperature. The cold sand is too much of a heatsink for thin parts like the ones you were making. Also I noticed no radiuses on the gates??? Any who,.......Merry Christmas.
@swdweeb
@swdweeb 3 года назад
Yeah, I'm not so sure about that. I hate cold sand so I keep it in the house the day before I'm going to mold with it. I used hot water to rehydrate it too. I mean I suppose it's possible but... I've never radiused my gates of the runner. If anything I would think a sharp corner would form a hotspot and keep the metal warmer. I'm going with the idea that it needed venting and ignoring the fact that the second mold poured just fine without venting it. 😄

@@swdweeb I never used to radius the runners or gates until I read the John Campbell book. Radiuses keep the metal flowing at a constant velocity with minimal to no risk of air entrapment or undesirable turbulence , while keeping the metal flowing at the desired temperature. It also eliminates the chance of cavitation/tunnelling of the sand, further reducing the risk of sand contamination in the casting. Anyways that was my 2 cents worth.

@christopherrajcoomar2744 3 года назад
Just stumbled across this vid now in Feb. Dont know if you'll see this comment but in small narrow area's like that corner the surface tension of the molten metal can become a possible problem. Aluminium is not a very fluid metal ( compared to cast iron and copper alloys, look at how they flow all watery like, A drop of aluminium just wants to ball up).Basically the hydrostatic pressure driving the metal to flow cannot overcome the surface tension as it is greater at points like this. By increasing the head pressure ( A fluid mechanics term) of the metal ( Fatter and taller risers) could solve this problem. Just my 2 cents I'm not a professional foundryman but have been casting on and off for 10 years.
@swdweeb
@swdweeb 3 года назад
I'll reply to both your comments with this one. I try to respond to every comment no matter how late 😄 I responded to one last night that was on a video from two and a half years ago. Those are a bit harder as I generally have no idea what the video was about. I've found that aluminum is actually reasonably fluid if I pour it at the right temperature ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-yTd-8l1PEHc.html for example. I was trying to remember if I had my thermocouple at the time I poured these trees. Seems like I got it somewhere in that timeframe. I was told by a good friend that runs a foundry that they typically pour their aluminum around 1325F. Sometimes they go as high as 1350F but not often as he said it creates a large crystalline structure in the aluminum if they get that hit. I'm generally not a huge fan of head pressure... I know I'm standing out in an empty field by myself when I say that. This video might explain why ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-pSgF7B55Fas.html. I'm also not a real engineer, I wrote software for my career, but it would seem to me that pressure is derived by the height of the column of fluid not by the volume of fluid. (Please feel free to correct me if I'm wrong on that count). That said, the height of my sprue ought to provide the pressure. I'm also not sure that a large feeder would be able to force the metal into those corners as I expect the metal would have frozen right about the same time the feeder started to rise. The part and the feeders should stay at the same height until the part cant fill anymore. Then the feeder will begin to rise above the part. Thanks for your thoughts. As always questions/comments like yours cause me to think about what I'm doing and why. If you've been casting for 10 years or so, you've been at this game a lot longer than me. I always being able to learn from guys with more experience than me
@christopherrajcoomar2744
@christopherrajcoomar2744 3 года назад
@@swdweeb Thanks for the reply! You're certainly correct that the head pressure increases with height not volume (i must of been half asleep when i wrote that). Saying that! In that specific case it might of solved the mold filling issue. Watched the vid you mention in the reply. You cover the topic of head pressure very well. I think with all castings made you have to reach a kind of compromise (how good a surface finish is acceptable, how much porosity is acceptable and so on). If you're chasing near perfect surface finishes and as cast tolerances you're asking too much of sand casting and need to get into investment casting. If you're in contact with Professor Campbell to get your questions answered, well you certainly went right to the Top! I take it you've read his books! he mentions how castings that were all acceptable at automotive inspection criteria, only 25% of them passed aerospace inspection. So it all a relative thing to what you consider acceptable. In my opinion, there is no perfect rules for casting metal that if you follow all of them and all your calculation are correct you can guarantee a perfect casting each and every time! Your vids are great! We all need to keep learning and testing ideas to reduce our scrap rate!

@@christopherrajcoomar2744 Yeah, I've been blessed to have direct conversation with Professor Campbell. It's been great. I learned today that some holes I see in the heart-shaped jewelry box are likely caused by hydrogen coming out of the water in my sand. The sand was way too wet when I cast rev one of the piece and better when rev two came out. But even still it was too wet. Another thing learned and another thing to work on improving. I probably am chasing perfection 😄😄 It's kinda like golf. When I started I was just happy to hit the ball. It doesnt take long to start thinking it'd be nice to get the ball to go in the right direction, then its to get it to go further then its to make par... casting is the same way for me. 😄
