SWM trials 7075 alloy swinging arm spindle and titanium engine mounting bolt
Here’s a 7075 alloy swinging arm axle and nut and a titanium engine mounting bolt for an SWM trials bike.
The alloy parts are off to Moss Metal Finishing for Surteck 650 coating, this is a corrosion resistant coating that doesn’t stress the metal during application. It doesn’t give a hard finish but that isn’t necessary with 7075 alloy, but it does need some form of protection as it doesn’t have great corrosion resistance.
I’m supplying a nice Probolt titanium flanged metal type locknut to go with the engine mounting bolt.
