4. Radial mount

My radial mount is made of piece of 6061 aluminum 3mm thick. First I cut it rough with hacksaw then I mounted on my lathe. First I cut the center hole, and then holding it from inside I cut the outer circle. The top part doesn't need to be round so I cut the top part flat with hacksaw. This mount still can be lighten up without weakening it, but the save may be 0.5 oz or less. I didn't bother. Four aluminum stands off and four screws are also included in the total weight. It is difficult to see it on the picture, but on stand-off is 2mm shorter. It is how it fit the engine. Three are 15mm long, and the shorter is 13mm long. Hole is 4mm for 6-32 screws and outside diameter is 8mm.

Total radial mount weight is 2.2 oz
