    Thrashing machine

    Not much help in the present time, but there used to be Balerman selling plans in 3" and 6" scale for a Case type baler. Maybe someone has a set gathering dust in the attic. Try asking also on the Smokstak forum https://www.smokstak.com/forum/forums/scale-model-engineering.54/ Dave The Emerald...

    BAZMAK-Diary of a Myford ML7 lathe restoration

    Leaky Check Valve

    Instead of tapping the ball, another way is to glue a ball to a rod that has been centre drilled and twiddle the ball back and forward on the seat to burnish it. Just a few twiddles usually does the job. The rod should fit the top part of the valve to keep everything normal. Obviously a new...

    Used Computer Hard Drive Parts

    It's been quite a long time since I stopped collecting hard drives, but from memory the bearings were a 'press' fit in the holders. I tried initially to bash them out but that of course didn't do the bearings much good! Using a steel ring that was a similar diameter to the race and hitting...

    Used Computer Hard Drive Parts

    I saved the discs for an as yet (and probably never will be) unbuilt Tesla turbine. The hub spacers would be the spacers between the discs. The bearings have come in handy over the years for small models' crankshafts, etc. Put one of the magnets in a plastic bag and you can use that to pick up...

    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. Worn bronze valve stems, bumper sub spline bushings were always good. The best I ever got was a BOP wear...

    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...

    Edison dynamo

    When I wound the coils on my dynamo, I Thought I had them wound like a horseshoe magnet as shown in Bluejets fig 1. There is only one layer of copper wire in the coils and the neo. magnets were to try and make up for the lack of coil layers. The magnets were placed in the bridge N down on...

    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...

    HMEM will be having a software update later today

    I use Pale Moon browser with Win 7. The only way I could log in was to click on Angie's name in a private window. If I went then back to the normal page, I had to log in again but couldn't, so here I am through the back door, so to speak from Angie's name. Dave The Emerald Isle

    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...
