    The leaker underneath the central 4-eared embossment is caused by inadequate packing. As you re-use your sand, it can become contaminated and not flow as well under vibration as fresh dry sand. When packing, if you pour a liter or two of fresh sand into/around overhangs and potential problem packing areas, it can help eliminate these problems. Pack in stages as you fill before the flask weight increases helps if your vibe is underpowered. The little BBs are caused by surface tension between the foam pattern and coating. If you spray your foam patterns with soapy water (usually dishwashing detergents are best because the anti-spotting additives are surfactants), this helps eliminate them, and so does working all surfaces with a soft brush as you apply the coating. Best, Kelly

      Thanks for the info, I didn’t think about the sand flowing less freely after being reused. Luckily all of the Leakers released after thinning them with a die grinder and another tap with a chisel.
      I did brush on the plaster and use soapy water on the pattern but still had some small bubbles. Maybe my plaster was slightly too thick? Or maybe I wasn’t brushing it enough . . . Either way I’ll see if I can make some changes for the second pattern before I cast it.

      ​@@OddsandEndsMachining Machined foam has very high surface area and strongly repels water. Surfactants help break surface tension but also using a deflocculant or dispersant instead of water to thin your plaster can help. These substances reduce the apparent viscosity of the plaster and improve how it adheres, levels, and covers the foam surface. A common deflocculant is Sodium Carbonate (washing soda). A common dispersant is Acrylic found in commonly found Acrylic Latex paint. There are several RUclipsrs that use Latex paint and plaster for refractory coating with success. It usually takes relatively small amounts and some experimentation. Best, Kelly

    Don't know the source of the wheels you used for the pour but Australian made cast ally wheel were CC601 and do respond to heat treat but will age harden as well, excellent work, just a suggestion if the line in the casting is to deep to polish out maybe gouge it out a but with a rotary burr and weld/blend with a tig weld

    Hey Jonno have. You got any idea what the best Ali /alloy is to lfc of engine crankcases is ? I’ve had a bit of a look but no luck so far I’ve been advised that casting my baby v8 cases is the way to go ( marsh Motorsport) apparently fabbed Ali cases will expand too much. Not what Chu want!! Looking forward to more V4 vids it really got the juices flowing along with my lill project hope fully getting the cranks ground this week to sleeve the main journals to 35 mm for gsxr 1000 main bearings 🍻👍

    • @OddsandEndsMachining
      @OddsandEndsMachining  3 месяца назад

      I believe fabricated cases can work, you just need to have tolerances to match. The block might require a meticulous warm up procedure to get everything into spec.
      I used alloy 242.2, it’s just what the foundry here uses, check out the link it’s very helpful. I’ll get back to the V4 soon I’ve got the crankcase patterns made but I’ve been working on the new v twin. I’ve got the machining about 85% finished so I’m probably due to start editing a video soon.
