"Red Neck" .049 elec. starter

Sounds simple enough , of coarse i will wait till it fails first

My original starter to reiterate; has a pressed-on "gear" on its output-shaft. Your average garden-variety brushed 540 series can-motor that I cannibalized from a little Coleman "Inflate-All" 12V air compressor.





I use a short length of 5/16" automotive fuel-line/hose as a "cone" to engage the Cox .049/.051 aluminum spinners. The clamps I'd been using to hold the hose onto the gear worked ok.. but the imbalance could be felt when pulsing the starter. Now that I think of it; that would ultimately transfer to the engine's crankshaft.. causing premature wear to the surrounding softer and non-bushed aluminum case.

I had thought about how I could improve this.. and it's definitely "by chance" that I had the correct size materials that I needed. A snug-fitting alloy sleeve (brass tubing) for the hose (cone-part) to be used. The hose expands slightly when mounted-onto the gear. The brass sleeve forms a compression-fit.. but needs a lubricant to assist in "sliding" it onto the slight bulge.





It's my "go-to" starter.. so this was worth doing.
