Click to view attachmentwhen you put your bog , the timing of putting the jig head is importent ,to quick and it sinks.
to slow and the bog has started to harden. i like to put a bit more hardener in soyour not waiting to long.
when bog goes in I put the mould on a flat surface and shacke it from side to side and like a vibraiting motion or quick tapping on bench this makes the bog settle in all corners and allows air bubbles to come up.
before you place in jig spray it with WD or any other lubricant, it makes it easy to get out when set other wise it will be stuck.
when doing second pour againg lubricte jig head and the face of the hard bog surface this allows you to pull it apart.
hope you can read the davinci drawings any Q. ask Doctor phill
