Possibilities

This is a video about the possibilities of anyone making a casting as good as this one. It centres on the mistakes and traps that many fall into and that if avoided will lead closer to this sort of result.
I have obtained the examples of the traps from other's videos. I do this not to denigrate others but rather to provide helpful clues on how to improve. These others shall remain nameless. I hope that all see this video in this light - if so it is my hope to do further videos explaining in more detail and showing preferred methods. I am indebted to EFI Hardware - my customer for these throttle bodies - who have been kind enough to loan this sample to me - Check out there web site for more information on their products at:-
www.efihardwar...
Note that while my comments in this video refer to green sand, my area of expertise - I think they apply equally to petrobond.

What about taking on an informal helper. I bet there would be loads of people who would jump at the chance.

[@olfoundryman8418]

@@johnkelly7264 Yes, this has been suggested before and I have had discussions with one or two people but nothing ever seems to quite come of it. I am amenable to the idea but there are difficulties - it is much easier to show someone how to do something that it is just to tell them. There are things like getting the sand ready the day before helper(s) turn up and currently I am not able to do this as it is physically demanding. At the moment I doubt I could last for the 3 plus hours that a typical moulding session takes without at least an hours rest. But if anyone out there is serious about wanting to be a helper and lives close enough to Croydon Melbourne Australia then I would love to hear from you.... Martin

elitearbor, Thank you for saying so. I do plan some more videos of the "what to do" kind. I am a bit uncomfortable with the "what not to do" type as it gets very close to denigrating other foundry video makers so another one of that type while possible is as fair way off - it takes some time to collect examples too, even though there are lots out there 😱 Putting them into a watchable video is a long winded process too, that video took about 3 months to do...

[@olfoundryman8418]

Growing, Thank you for your rather nice comment. I had great trepidation in releasing this video as I feared for a lot of bad reaction, wonderfully I have to report that I have not had even one bad comment🤗. I did try to make the - ahem - borrowed clips as anonymous as possible but it was obvious that where they came from would not be that hard to determine. However, for four reasons I will demur on your voice over idea. 1: Ripping apart just one persons single video is just a bit too personal. 2: I have in the past provided information like that (sort of) privately to people just for their own private use, but they have used it to release "50 ways to leave your bad castings behind" videos as though they were an expert even though they have made at most a handful of very ordinary castings. In doing this they have released information before I had a chance too, thus robbing me of many video ideas. This has happened to me several times and several times bitten most definitely very shy. This is very mean of me I know but I too have a right to a little YT success 3. Because of 2 any critic would have to be a released video on my part i.e. public. To "attack" another youtuber so publicly and completely is not my way. To cause them embarrassment in front of other youtubers (most of whom are equally as bad I might add) is not something I wish to do 4. I looked at two of your videos - your latest melting down aluminium wire and one where you melt down a large ingot of (the wrong) zinc alloy to make a hideously bad mould rammer design. At a quick look in the first of these there was 15 mistakes in the second about 30! Many were only small mistakes but some were big....... Martin

From your #2 last sentence, Its not mean of you, I’m surprised more people aren’t subscribed and watch your videos, and I’ve never given you a shout out yet because, as you can tell, my techniques that I’ve tried to teach myself and “learn by doing” would be a discredit to you 🙂 -although I should ACTUALLY try some casting tips from you(to better myself) and add a title that I learned it from you and tell people to check out your channel. Maybe I’ll try that this weekend 🤔 I’m a comedian at heart, so the idea makes me giddy, and I’m old school so nothing hurts my feelings like that. I even had to re-read #4 in your voice(which is the best, not joking about that) and I can picture an ‘Ozzy man reviews’ style video of the zinc sand rammer video. “Aaannnndddd we start right off the bat with the worst design of a sand rammer you can possibly choose. He’d have a better bit of luck with it if he just shoved it up his tailpipe. Oh wonderful, he’s chosen a zinc alloy, albeit the wrong zinc, but by the looks of his “shop” if you want to call it that, he obviously can’t afford a quality zinc alloy. I mean come on, is that plywood on top of a shelving rack??” 😂 Sorry, I’m a little kid at heart and think that kind of stuff is funny.

I hope you can find something that can help with the back pain, we are rooting for you and your pain-free future.

[@olfoundryman8418]

Mr Eric, You bought the big book - you are a glutton for punishment! Even as an experienced foundryman and a qualified Metallurgist there are parts of it that I struggle with but it is a great resource. I go to see a surgeon about the possibility of pain mitigation surgery (tries one and two failed) in a couple of days - maybe I will get lucky this time. Pain free is most unlikely but a good reduction is a possibility...Martin

Or Luckygen1001 a 40 plus year cast iron veteran, like me he speaks his truth. But yes, YT has a lot to answer for when it comes to spreading misinformation, nothing that they can do about it though. Its up to the viewer to sort the chalk from the cheese, assuming he knows the difference of course and sadly, he often does not.... Martin

Martin, always a pleasure to hear your well experienced and solid advice. There are so many atrocious casting video's out there and beginners follow using the same atrocious failing techniques. Your advice is spot on, read and understand the materials you are working with and above all observe and analyse not only what goes wrong with your castings but what went right and develop your rules accordingly. Had a chat with Dave at Outlaw Castings at Lake Goldsmith, he is doing some fine work in his set-up, great to see someone who knows what he is doing passing on his experience in his casting demonstrations.

[@olfoundryman8418]

Cam, It was actually a few of those bad videos that got me on to YT, I felt the compulsion to try and counteract the bad info out there. Sadly my success rate had not been all that I might wish for but clearly I am reaching some people including I think those that actually want to improve rather than just get more views... Martin

[@bobvines00]

I/we look forward to more videos expanding on this theme. There are too many unqualified people showing how _they_ made (or tried to make) a casting being carefully watched as "gurus" by others who know even less, but want to try their hands at casting.

[@olfoundryman8418]

Bob, Working on more videos. I began publishing videos after looking at some of the early "gurus" . I was trying to present more accurate information - an urgent need. These early Gurus had at least developed some skills but scientifically they were way off and did use some crazy methods - they still do! 😱. The newer crop of said gurus have nether science nor skill and present an altogether horrid idea of foundry. While I do not like their efforts I temper my dislike with the knowledge that they are not actually trying to produce anything useful but are really just after YT views and subscribers. If they thought they could get more views by plucking chickens they would pluck chickens. The people I reserve my deepest dislike for are those who deliberately and intentionally try to act as authority educators. Worse still I have had a few who have taken private information I provided to them in order to help their own efforts and use this information in a "50 ways to improve your castings" type video. One of these people is known to have made less than a handful of castings himself! Many of these so called educational videos have been real shockers, full of absolute rubbish, but sadly they often get lots of views....Martin

[@bobvines00]

@@olfoundryman8418 Martin, yes, I agree with you completely. I've never tried my hand at foundry work, but do have a half-dozen or so casting/foundry books and also watch YT videos with a _critical_ eye to pick out useful (i.e., correct) information. I look forward to any videos you can create!

Always loved your videos and will stay with you for as long as you make them.. I started out inspired by turdpolishers, and stayed because of people like you. I do this because it's challenging and interresting, even though I mostly cast bars and coins in open top moulds (Norway is a hard place for hobbies like this so I can blame lack of availability) Keep up the amazing work in your videos Martin. Lots of respect!

[@olfoundryman8418]

Gizmos, I thank you for your loyalty. Its my aim to make lots of videos for a long time but - eh - well - that may not happen, in fact its unlikely. Open top moulds are a bit of a dead loss (IMHO) you need some pressure to overcome the surface tension of the metal and thus get it to take a sharp impression of the mould - is there a way that you can find to have a top on the mould say 50 to 75 mm high? Perhaps a split top half that just lifts off (but is clamped down for casting) and splits sideways to release for the now top bit of the casting.... Martin

Oh this video was an eye opener!!! Thank you for taking the time to explain what doesn't work well when casting. Well done!

Ben, Surprisingly not that many failed castings. A lot of trouble early on that's for sure but I quickly learnt to stop using any old junk metal and buy decent ingot 90% - of my problems suddenly went away. Why waste all that time and effort making a good mould and then fill it with unknown junk. It is fair to say though, that by the time I made the casting featured here I had had a lot of practice - a hell of a lot 😊... Martin

[@benjet8675]

@@olfoundryman8418 no doubt Martin! Thankyou for the response and the videos again. I too am a disciple of correct metal choice and tools, especially considering the simplicity and millennia of refinement of foundrymen past. Being an aluminum welder by trade I've luckily had great training in the hundreds of of alloys out there, and the coke can stuffed crucible obsession on youtube makes me roll my eyes constantly, making your latest content all the more important. Just having someone set the record straight on fundamentals is needed. What turd polishers do afterwards is up to them, but at least it's out there should they care to progress with something worth while. I look forward to your next project.

[@benjet8675]

Hey Martin what do you use in the way of a swabbing brush? I've tried many brushes over the years, never a legit camel hair . In this day and age in Melbourne they're hens teeth, would there be a somewhat similar alternative in your opinion? That is, if you even use one at all. Any thoughts or leads on this matter would be greatly appreciated! Cheers.

[@olfoundryman8418]

Ben, If by a swabbing brush you mean the brush used to paint the edge junction of pattern and sand with a little water to toughen the edge as an aid to clean pattern withdrawal (as seen frequently in the videos by the genius moulder d. laszlo) I do not use this practice as with my very fine sand it seems to cause slight blows where the sand is thus made extra wet. The brushes that I do use on my moulds are simply soft artists brushes that I buy from Bunnings. I use two sizes - the one I have in my hand right now is a size 20 and is marked Renoir 7120 1660217. I think but am not certain that the smaller one I use is a size 18. These are quite soft and MAY serve as a water swabbing brush - you will just have to try them out..... Martin

[@benjet8675]

I know the ones your using, as it seems that it's mostly personal taste as opposed to strict type, the brush with my name on it will turn up eventually. Luckily I enjoy painting in all forms so a surplus of different styles of brush are all welcome in my shop. cheers martin.

That spherical bottom pouring basin for example - the shape just makes the metal ricochet out if you try to keep it appropriately full during a pour - hardly mattered in this case with the blocked sprue and all (happens to all of us).
