I was on HPA and found this spinner process that looks really easy (especially for me ). Go to reply #14.

My current favorite nose block/prop bearing is the round block with a 4.25 degree angled bearing(and jig for drilling this angle).  This is developed from an article in the FAC Newsletter with the title (I believe) Why the Long Mug, Is Your Noseblock  Not Snug?"  This is close if not the actual title.  Great article showing how to make the noseblock and set us the angle so that just by twisting the block down thrust and side thrust that is usually the most used...3 degrees down and 2 degrees right side thrust.  This for tractor prop setups.  Here's some pictures of the construction of this propblock/noseblock used on my Bf-109 E3 and the nacelles on the Connie.

Hi Y'all, I've been looking at various Nose Blocks/Prop Bearings I've used on my previous models and thought I start a thread for us to post our favorite Nose Block/Prop Bearing setup we prefer.  I'll be adding to this thread over the next few weeks as I go back through my builds and see if I can find pictures and explanations of my block and which I preferred and some I've made.  Here's some pictures of commercial propblocks/prop bearings available.
