Metal Working Decisions - Do You Cast or Fabricate.
To Cast Or To Fabricate.
Some metal working projects have a fine line between the decision of whether to sand cast have you ever had a project where you cannot decide whether to make a complex pattern and attempt to sand cast. Or to leave the casting equipment in the corner, and decide to fabricate the part instead.
Now, when you learn the tricks and techniques of sand casting, you are normally hell-bent on casting everything in sight....have you ever thought that the part or project you about to embark on may possibly be quicker to fabricate than to make a new pattern, then go through all the mould making processes, then melt, and finally pour the molten metal.
There have been several times in my workshop where the latter (fabricate) has been the most economical, and the quickest way to produce an item in steel, instead of cast aluminium. The biggest problem that I have noticed with a lot of hobby casters, is the lack of machine tools to carry out fabrication operations.
Now I don't mean to denigrate those that do not possess general workshop fabrication skills or equipment, as you may never have had the opportunity to learn them, but it is not that hard to learn how to operate the following machines.
And the essentials ones are:
- Bench or pedestal drill complete with drill table vice and a good set of high-speed steel drills.
- The usual workshop hand tools, (to many to mention)
- A small oxy-welding set, and possibly an arc welder 150 to 200 amps.
- Bench grinder (1HP) fitted with a linishing belt (multitool)
And if you can afford one...
- A small screw cutting bench lathe, which can be bought from dealers or private sales. This item mayseem like an expensive luxury item, but it will pay for itself many times over, believe me.
I may have mentioned in a previous newsletter that the more metal working skills you acquire the easier your metal casting becomes, simply because you are able to produce so many items of tools & equipment your self. All the projects detailed in our hobby foundry ebook can be built using basic workshop skills.
If you are really serious about building all of your own gear or fabricating special tooling etc, then why not use the vast resources offered by the tech colleges in your own community. Enrol in the night classes, whether it's to learn welding, machining or whatever, there are hundreds of thousands of dollars worth of gear sitting idle in these colleges, so make some inquires, enrol, and get to use some of the gear bought, and installed by your hard earned taxes.
