Experimenting With A 2stroke Trimmer Piston

[petcnc]

Piston 'strength' with holes drilled shouldn't be affected, drilling holes would lighten it ever so slightly and it's 'apparent weight' would be substantially lower at 7~10,000 rpm (inertia makes an 'ordinary'1lb 85~90mm piston weigh around 5~7 tons at 7~9,000 rpm TDC when it has to 'stop dead' then reverse direction. As long as you don't remove material too close to pin things will be fine

Thanks! I will try it and let you know of the results. At the moment the weather is not the best to work in the garage.

LOL, I'm in central Florida and garage is downright chilly at present. almost 10:30am and only 46f, usually high 60's this time of year. Weatherman just commented, should be 70~71f expect high 58f. Compared to further north it's 'warm' but 20 below normal feels pretty chilly
