Metal Casting at Home Part 54 Oil Fired Furnace Build Part 6 (Re uploaded)
This is the final part of the furnace construction showing it in operation although there will be one more showing how the brass badge was made. The first crucible full of metal took 20 minutes from cold and subsequent ones only 10 minutes. 5 ltr of uncut used motor oil was burnt during the 90 minutes the furnace was fired. The burner nozzle was supplied with air at 15 psi. More furnace details can be seen here http://myfordboy.blogspot.co.uk/p/d...
Metal Casting at Home Part 5 Backyard Foundry Core Making
Making sand cores as used in Metal casting at Home part 1 and 4
Metal Casting at Home Part 55 Casting a brass label/plaque/nameplate
My Kasenit furnace has a nice brass label on the side. To give my home build a professional finish I have cast a similar one to add. I am using the electric furnace on it's side so a larger crucible can be used. The main function of this particular furnace is for enameling.
Metal Casting at Home Part 6 Preparing the Moulding Sand
A short video showing how the sand is prepared for use.
Metal Casting at Home Part 56 Tool Caddy for Safe Working.
When working with hot metal safety is important so tools are taken from this caddy. Stops you tripping over them when they fall on the floor. Also shown on the video is an improved latch for my crucible lifter to handle the extra weight of using a larger crucible. The noisy compressor in the video has now been replaced with a quieter belt drive model. The furnace has now melted iron, sorry no video.
Metal Casting at Home Part 7 Oddside Mould Making
Making a greensand mould when there is no flat surface to make the parting line.
Metal Casting at Home Part 58. Brass Flywheel
I thought I would try a brass casting for a changed now that I can easily melt brass in the new furnace. Liquid gold!
Metal Casting at Home Part 8 Pattern Making
Showing how wooden patterns are made to make greensand moulds.
Metal Casting at Home Part 59 Oil Fired Furnace Operating Instructions
Here are more detailed instructions showing my furnace in use. You can see how with careful design using waste motor oil is not dirty to use which was one of my concerns before doing this project. More furnace details can be seen here http://myfordboy.blogspot.co.uk/p/d... The casting shown is for my Stove fan https://www.youtube.com/watch?v=ISD... Castings and plans available for sale.
Metal Casting at Home Part 9 The Furnace .
Details of the equpment I use in my home foundry. More details including plans can be found at myfordboy.blogspot.com
Metal Casting at Home part 60 Spoked wheel Castings
Moulding these wheels is a little tricky and care has to be taken to remove the pattern without damaging it. I used some wood screw to reinforce the sand between the spokes. I have shown mould making many times so I have left out the captions on this video but if anything is not clear feel free to ask by making a comment. These castings are for sale.
Metal Casting at Home Part 10 Another Day in my Home Foundry
How to make a casting from making the sand mould to the finished item. The video has been edited to fit the 10 minute time limit of You tube. It takes much longer than this!
Metal Casting at Home Part 62. Detailed Pattern Making. The Myfordboy Steam engine.
This video shows in detail how the pattern was made for a simple model steam engine. Also shown is how a core is made to make the inside hollow and the casting of the part. The engine will run on steam or compressed air at 5 PSI or less. The concept is for good looking, easy to make engine that could be quickly made, not highly detailed but better quality than a Mamod or Wileso model. The engine is double acting and has slip eccentric valve gear so it can be run in either direction. The engine frame shown here and a flywheel casting together with plans will be available for sale if you would like to make one.
Metal Casting at Home Part 11. Sodium Silicate & CO2 Core Making.
Making sand cores for a greensand mould using Sodium Silicate and CO2 to harden the sand.
Metal Casting at Home Part 57 The Foundryman's Lunch, Cooking with Oil
It seemed a shame not to use the heat left in the furnace after a casting session, so I cooked the lunch!
Metal Casting at Home Part 12. When Castings Go Bad
Things don't always go well in the home foundry.
Metal Casting at Home Part 61 Cutting Alloy Wheels for Casting
I have tried several methods of cutting up wheels for melting and the method show I have found works best. Special thin aluminium cutting discs in an angle grinder wear out too quickly. The Evolution saw runs at a slower speed that a woodworking saw and the Evolution blade cuts the metal OK but the fine teeth clog easily and can break off when cleaned out. The blade shown has fewer teeth so there is no room for metal to clog them.
Metal Casting at Home Part 13. Small Casting with Core.
Making a small casting in aluminium. A core is used to make the intenal detail of the casting. This is the gearbox for my Stickney engine model. There are some slight differences in technique from my other videos, I am learning all the time!
Metal Casting at Home Part 64. Casting and Machining a Toothed Pulley.
The video shows how a toothed pulley was cast and then machined. The pulley is to go on my spin indexer which will be connected with a toothed belt drive to an Arduino controlled stepper motor. This will enable any number of divisions to be indexed at the touch of a button. The electronics and Arduino sketch were devised by Gary liming and can be seen here. http://liming.org/millindex/ Details were also given in Model Engineers workshop issue 249.

Metal Casting at Home Part 18 Cantilevered Core
This casting needed a core to produce the required shape. The core could only be supported at one end so a cantilevered one was used.
Metal Casting at Home Part 69 3D Printed Patterns Part 2
My first 3D printed pattern worked a treat. The finish on the print did not need any sanding, filler or paint, it was used as it came off the printer.

Metal Casting at Home Part 20. Hit & Miss Engine Cored Cylinder .
Making a greensand mould and casting an aluminium cylinder for a model hit and miss engine. ( Blooper included ! )
Metal Casting at Home Part 71. Locating a Core.
The most frequent question I get is how is a core held in the mould. The core creates a cavity in the casting so, for example, it can be made hollow. Here are 3 different methods of locating it to produce a cavity in the casting. Another method is shown here https://youtu.be/1HuxDVpy_iU which also shows how the cores were made.
