Swing-Arms and guides

Jeffrey Goff · Post by **Jeffrey Goff** » 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

Your swing arms are going to look really good. Are you going to make this a static or RC model?

Hi Allan, I think this has to be R/C, but I will try to get as much detail as possible, although things are conspiring against me, I need to finish the belly inspection plates by milling out the bolt slots, after waiting a couple of weeks for a replacement PC board for the speed control, I fitted the new one and it blew again, so in desperation, and in Heath Robinson style, I removed the motor, and fixed my electric drill onto the spindle, sort of, at least I can do simple slots

Jeff,

Sorry to hear about the probems with the mill, perhaps its a duff motor taking out the speed controller. I had that with a washing machine once. The motor had failed and I thought it was worth replacing, so after struggling with that I then found that the speed controller had also blown. with all the work and the extra expense I wish I'd just thrown the machne away and got a new one.
