    This is the latest project outcome- a domed star. You can see the poor cutting on the punch in particular. I suspect the answer will be feed rate and drill speed adjustments.

    A few things come to mind- are you scrupulous about not adding in soldered joins? If not the extra impurities from the solder will not help things. Secondly, molten silver has a very high capacity...

    The usual "proper" way to do this is with a thin foil of platinum which won't oxidise. A thin foil of fine silver will also work to a point and be a bit cheaper/more accessible. Both of these would...

    Cone type shells should work ok, so long as they are placed at the right angle to remove without dislodging the sand (so the thickest outline is at the join)- once you try it you'll see how to place...

    or

    Glad it worked out for you, I thought the initial dimensions would be tricky.
    The formula works too: 4x4=16 mm cross section area, going to 5.5x1.7=9.35 mm area; 16/9.35=1.71 fold expansion of...

    I think without losing material you can calculate it- 4x4 square has 16 mm cross section, 5x3 has 15 mm cross section so the extra metal must go into the length: 16/15=1.066. So your new wire will be...

    You have two choices- if you want the loop in the plane of the item as you press it into the cuttlefish then it can exist in your master. If you want it out of plane (as in the example you...
