Hi Lads :wave: I have found some of the photos of my , furnace/foundry set up build ,,,,,, some may fined something of interset in them , first off , when i build stuff like this ,i don't work to any real plan , just an idea in my head of what i am after , what materials i have at hand or can scrounge up, thats why things end up the size they are .Some times i get lucky and things work out ok . I have always loved casting my own parts ,its great to recycle crap into some thing useful , anyway here is a few shots of my old furnace set up, i built it many years ago from bits and bobs from the junk yard , i did splash out and by a new elctric motor for the blower unit i made . Some of the castings produced with the furnace ,The furnace works great doing ally to iron , just it was a bit small in capacity . Getting to the piont , i want to do bigger castings/ pour more than one or two castings in one melt , so i need to make a furnace to take diss A16 crucible or bigger I started with an old chemical drum , the type with a seperate lid ,18" dia ,cutting a section off to make the mian body , and a section for the lid so the bead run in the middle of the lid , this is so the castable has some thing to key too Not wanting to waist the loverly rolled bead of the top of the drum i trimmed it up and fitted it by spot welding , to the main body , to make it a bit more rigid Then i made up the lid lift / swivel lever , this works of a cam on the lever and pushes on a rod fixed to the main body , when the lever is moved down the lid lifts verticaly 1/2 " and is easerly rotated out the way Next the rod for the main body , and some handels The blast pie all the metal work done the center former If your still awake , now its time for the castable , i filled the bottom of main body 3" thick , let it go green ,then fitted the center form the lid ,much of the same The former removed The lid was fitted and ajusted to give a level lift and some clearance between the cam and rod so the lid will seal flat on the body I made up a trolley for it so i could wheel it out side ( not my best idea /british weather ) also the plants were not too happy It did not stop on the trolley long , after some thought , i decided that i must have it so i could run the furnace indoors , after lots of messing about trying different ways of getting the heat out the shop , melting parts of my new shop , i decided to add some insulation to the main body and exhust the hot gasses out the back of the furnace through the shop wall . so a new stand was made , handels removed and lever repostioned . Hope that was not to long of a post Regards Rob |

Great post Rob. I may be using some of your ideas on my next generation furnace. I like the lifting mechanism on the lid. Dan |

Hi Me agian :wave: Thanks Dan , the lid is easily lifted and rotated with two fingers on the lever , also it save having to fined some were for a red hot lid when you come to remove the crucible . Moulding sand storage was always a problem , i used to store it in big plastic drums , bit of a pian in the butt , so i knocked up a moulding bech with sand storage built in , works much better , sand dose dot get everywere now , and not in shot is a small adition to the bench which has a joiners vice fitted , so the moulding bench doubles up for patten making Cheers Rob |

Thanks Rob, Very nice work .... again !! :clap: How much of the "cement" castable? did you use in this? |
| Rob.Wilson:
More stuff For those who are un able to get hold of castable stuff , this may be the way to go , i had some fire bricks lying about so i thought i would make a furnace from them , this is based on one i used when i was a young lad living with my foles , its from one of the workshop seires books , This furnace fitted with a grate and burning coke will melt cast iron Bricks , no idea how many, sorry its the wrong way round :doh: welded up base to fit two rows of bricks Lid made from C section build up bricks , leaving hole for blower (crucible in shot is too big for this furnace ) make steel rapper to keep it all together , the rapper fits into the base and is fassend up one edge the lid was filled with Ganister Anyway you get the idea ,,,,,OH if anyone WANTS the above please PM me , free to good home ,,,,,MADMODDERS MEMBERS ONLY Cheers Rob way to much typing for me :D |
