  • Pain in my fingers. And an Oil burner idea

    I used my burner today only had an improved idea, and guess what, it worked. Get a steel pan or capped pipe and fill it with oil about 1 inch up. then put socks in and light them. There is a little more to it but it burns.

    I lifted my crucible out of the furnace type setup and burnt my fingers on it through welding gloves. It hurts but it was my mistake and i have learned from it. I had my had in the wrong place even though i went through the process before i even lit up the burner.

    Shed,

    Don't try to pick up a hot crucible with your hands, no matter what you are wearing. You will get burnt. You must maintain some distance from it when you are pouring the metal to avoid splashes. The proper way is with some tongs. If you don't have tongs then you will have to figure out some other way to hold it at least 18" away that is secure and will not end up dropping it.

      Be careful, Shed! You're playing with fire--literally! Don't try to do any foundry work until you have the correct safety equiptment and material handling equiptment. A small amount of molten metal can do a whole lot of damage to your body!! Another thing, are your parents aware of what you are trying to do?

        My dear young friend take good advice these are very serious tasks you are undertaking. I have personally never done any sand casting but have over many years done many many lost wax castings in Dentistry .Metal which is moulten can cause extrmelly serious and even fatal wounds .even a splashback could cause you to loose your sight.Try to join a club and watch it being done quite a bit by others and even then only proceed with supervision till you feel absolutely confident.I am not trying to play a paternalistic role with you and greatly admire your enthusiasm but I would hate to see you get into a pickle moulten metal if dropped with a crucible can be one thing but even a little spillage is not something to take lightly.I do not wish you to get hurt please be cautious regards Alistair

          I have thoroughly discussed what i did wrong and how i can improve my ideas. And i built some tongs. But my fire won't get hot enough. I need some fire bricks.


          Thanks for advice and i understand that you are not trying to play a paternalistic role. And my mother always knows what i am doing. I am always in contact with my fathers with some type of "Modern" communication.

                good evening.

                yep. this kid is 13. just barely.

                i know this because it is my kid.

                the kid is precocious, to say the least. he lives with his mother in indiana. i am in Texas. kid came to visit me and liked my machines. he got off on this foundry stuff on his own and i don't have the knowledge to be of much assistance to him.

                the point of all this is to let all you guys know that i really appreciate your sharing your knowledge with him. we have had a long talk [on computer] about safety and i think [hope] that he will use a little better judgment in the future.

                he says that he has some tongs now and that he is better equipped than he was. i have also talked with his mother [who is pissed off because she now has 'junk in her yard' about this] and we thinkl that he is going to be doing better in the future starting now.

                this kid that we are talking about built the power file that was on the cover of one of the magazines a few months ago while he was visiting with me earlier in the summer. it was his first experience with the machines and it was great to watch. sometimes it was hard to tell the difference between the kid and the machine. he has some magic in his hands. it makes an old man proud, but it also scares the hell out of me because i know what they can do to flesh. i have tried to tell him that those machines are hungry and they don't care what they eat. skin and bones are the same to them as aluminum and steel. hopefully he is going to learn this easier than i did.

                thanks again to everyone for helping my kid. sometimes it is hard to be a long distance father. that's bull****. it is ALWAYS hard to be a long distance father.

                happy weekend. happy chips.

                  Happy weekend Happy chips, rotflmao. That is a good one, But i am pretty sure i am not one of Thrud's many personalities. Soon i hope to add a drill press a welder and a bench grinder to my collection of tools. And an update on my foundry is, it is cool, although it does not have enough insulation yet to get up to heat i did shape some aluminum. That was pretty cool. i love the idea of a burner that consists of a pan and old socks. It will work very good when completed. And it only used about 2 coffe cans full of oil to hang out with my friend and watch the fire(Not aluminum melting) For at least 2 hours

                    Shed,

                    Paternalistic nuttin, we don't want to see you or anyone else get hurt. Adults make stupid mistakes just like I did a few weeks ago. I decided to unscrew the tip of my soldering iron to change it for a lower wattage. I didn't let it cool down first. I used a thick rag to grab it and the heat came through faster than expected and I dropped it. Then the idiot reflex kicked in and I grabbed it out of the air with my other hand. Burned the crap out of my hand.

                    If you are going to melt metal BE CAREFUL! Those tongs you built, with the crucible cold put a bunch of gravel in it and with the tongs give it a shake. Try throwing the gravel with the crucible and tongs. Make sure you have a good grip that won't let go. Practice pouring the gravel into a small can without spilling any. Then try using it to boil water. Practice pouring the boiling water. If you get some on you it will burn you but not like metal will. BTW, don't get water near molten metal, as has been said before. You will need some fire brick. Make sure it IS fire brick, not regular bricks. Have you gone to the local library and read up on this?

                      I got smart, I let other people do that kind of work. Too many tongs and gloves causing burns.

                        Jesus H. Murphey! I think you had better get a book on casting first and read it cover to cover. What you are undertaking is extremely dangerous! Even professionals in the steel industry get hurt and killed from accidents and they are taking far greater extremes in safety than you are. The only gloves that should be used are fire suit gloves. In fact an entire firesuit, pants, boots, jacket, hood, and gloves should be used to reduce the chance of injury. Proper tongs to fit your crucible is critical.

                        In addition, your mother should be present and observing from a distance in case of a catastrophe - phone in hand.

                        This is dead serious stuff - do not take the required safety procedures lightly!

                        Hey, I was young and indestructable once too - I did things that could have gotten me killed in the blink of an eye - I am lucky enough to be here to tell you not to take the chances - it is not worth it and eventually you do pay the price for "stupid human tricks".

                          Hi Shed,
                          I know you learned from the burn and it wasn't a bad burn. A point I would like to make is that the difference from a slight burn and a tragic disfiguring burn probably isn't very great. That means that it is what you don't yet know that will bite you. On the other hand you have learned more from that slight burn than you will ever be able to teach the next guy who will follow in your footsteps. Your father probably learned the same way you are, but he may have had the benefits of the experience of your Grandfather or someone else to guide him. Ok nuff said.
                          I don't think I'd advise you to stop what you are doing, but to go slow and also to deal with small quantities at first. You can do some great first castings with less than a cup of molten aluminum.
                          Also I think you are off track if you are thinking that you aren't getting hot enough because of the insulating factor of your forge. An insulating factor might come into play as far as being efficient would go, but primarily you must have fuel and air in the right proportion. The amount of heat energy in a fuel is tremendous, and the rate it is released is related to the air available. I would recommend propane. Insulation is unimportant because you are releasing so much heat that the insulation is only there to contain the heat or redirect it. It doesn't assist in getting up to temperature. If you aren't getting hot enough then you don't have enough air or fuel or both. In my forge I light it and put some propane to it. If flames start to come out of the exhaust port then that tells me that the propane is not being consumed inside the forge. The only reason that would happen is if there wasn't enough oxygen. So up goes the air flow. Not hot enough? Then more gas. Flames coming out of exhaust port? Then more air. With propane and a controllable blower you can get very hot and you can get it very fast and it doesn't depend on insulation.
                          Good luck, and don't learn too fast. You might pass us by.

                            Spence;

                            i was trying to explain the same thing to hm yesterday, but didn't have the right words in the right order. thanks to you as well. he has built an oil burner that iwll shoot a 6' flame. i would think that if he could refine that a little he might be ok a far as the melting goes.

                            Dave; been a while since we talked. how are you? thanks also for your words of wisdom.

                            in our [long] conversation yesterday, i told the kid that i was not going to help him any more unless he got that idea of 'safety' ppermost in his mind. i hope maybe i got through, but i am a 150# weakling. perhaps i could threaten him with you.

                            this all good advice.

                            LISTEN, John.

                            happy saturday to all. shop is calling.

                              i am not smart enough to figure out how to edit a post.

                              i forgot you, Evan. thanks also for your input.

                              i always try to do dort of the same thing with setups. walk around it a little and see what is gonna jump loose or be out of balance, etc.

                              thanks again, guys.
