Swing-Arms and guides
Posted: Sat Sep 05, 2009 7:16 pm
Not sure if this is of any use to PZIII builders, I am adding the guides to the back of the swing-arms, and the corresponding blade and bracket on the hull, and these will be fully functional, my first effort I used steel, but on reflection it would be prone to rust, so I remade it in alloy;
there is 7mm clearance from the bottom of the arm to the hull side, so the "L" shaped bracket is 2.5mm thick, and the guide arm is made from 3 pieces 1.5mm thick, the hull blade bracket is 2mm, and the brass guide blade is 1.3mm thick, so it runs inside the groove, you can use this modification on the standard swing arm, you just need to file a flat on the rounded bottom of the swing arm so the "L" shaped bracket fits snug, have included the templates I used so you get the idea, and pictures of the first steel guide and the alloy one fitted
