    Reusing scrap

    I also used to work in the offshore oil industry. I liberated many pieces of scrap metal, mostly non ferrous, but also steel bits that would come in handy; anything that would fit in my bag.

    Centering a cast flywheel

    A small addition to Ian's reply. When you set up the flywheel in the chuck, get the inside of the rim running as true as possible. You can always take a slight cleanup cut on the side of the hub to minimise any eccentricity when you are tready to bore the shaft hole. (Only the outside needs...

    Radial engine plans/kits

    If you want to run on glo plugs, also think about the electric power requirements for multiple plugs. This issue has been discussed in other topics (much) earlier on this forum. From memory it was concerning the use of Cox glo heads in multi cylinder applications. Dave The Emerald Isle

    Wiring up an Parvalux sd21 motor HELP !!:)

    The original Unimat motor looked like a typical sewing machine motor. The later U3 lathes had motors double the power but were only rated at 50% duty (10 mins on, 10 mins off). So, if looking for a new motor for your SL, then consider getting a more powerful motor than original and one that has...

    Wiring up an Parvalux sd21 motor HELP !!:)

    Attached is a wiring data sheet from Parvalux to help you. The capacitor you require is 2.5Mfd. I note that your SD21 motor has only a maximum power of 20 Watts (2800rpm version, 1400 rpm version is only 8 watts). I would have thought that this would not have been powerful enough to drive your...

    Cross slide bushes

    What you describe as a 'Bush' is known as a Gib Strip. It is used to remove play in (this case) the cross slide. The cross slide should have a number of set screws that bear against the gib strip that should be adjusted to remove sideways play, but not so tight as to prevent free movement of...
