    Default Material Source for hobbyist machiners

    I have found a great source of material for projects. Pop around to your local Supaquick, Hi-Q, Speedy Exhausts etc, etc. In fact, any business that replaces motor vehicle shocks. Ask to dig in their scrap bin for the old shocks.

    I collected about 20 from various shops yesterday. This is what I have salvaged so far. Solid bars in various diameters, as well as the damper tubes. These are seamless, perfectly round, come in various wall thicknesses and are going to be ideal for making a rifle suppressor or 2.



    Care just needs to be taken with dismantling them. I recommend drilling a small hole (2mm) in the bottom end of the shock before cutting it open. Not required for all shocks, but some of them contain about 10bars of nitrogen. Cut it on the top end and your whole workshop will be covered in oil. Drilling the hole releases the pressure so that the top can be removed and the shock then inverted to drain the oil.

    I wonder what material they use. ?

    Some of it is quite soft. I have found that some of the smaller diameters can be hardened, so they at least have some carbon content. I would check the hardenability (is that a word?) before I use it for anything that needs to be durable.

    I don't really build models if that is what you are referring to. I do, however, make tools and stuff because I enjoy it and because I can. I do not have the time (or inclination) to document all of them, but here are some of my projects.

    At present busy with a vice stop for my milling machine and a ball turner for the lathe. The vice stop will use some of the material from the shocks above.

    Talking about alternative sources of material a friend of mine uses old saw blades (metal cutting) to make knives.

    Used circular saw blades (and chainsaw bars) are great too.

    Back when I still used to build and fly RC planes, I'd also stop by the local tyre spots to get used wheel balancing weights for the lead. Works well for getting the COG correct on larger model aeroplanes.

    Ian I never knew you flew RC? Did that as well when I was a laaitie.

    That source of lead has pretty much dried up though. Lead is worth money nowadays.

    So I have realized that some of this material is extremely hard. Here is the first project completed using the 2 thinnest shafts.

    Vice end stop.
