Porting a track?

[leech~~]

I had seen some things on Utube about porting a track. Any one do this? Pros & Cons?

2 Reasons for porting a track are to lighten the rotating mass and faster 'dumping' of the snow from the under carriage.

I see it in the Mtns on a few machines but not many.

You don't see it here in the 'flat land' mostly because it shortens the life of the track, I hear they can't take high speeds for long periods of time.

What are you up to LEECH??????

Bored waiting for some good snow and or ice and no good projects it sounds like I can do until then!

I think I did see a pic of one track that came apart and it looked like it delamed right at one of the holes?

So maybe I will skip that project!

The biggest reason as mentioned is rotating mass. Every 1 lb of rotating mass equals 7 lbs of stationary weight. And was mostly a mountain thing.

Thanks slurpie, I had the "what for's down" was just wondering if anyone had done it and how it worked out for them? Like Mn Mike said, doesn't sound like a lot of folks in MN have done this or had a need too?

It's one of those things you do. When I used to go out west we did it, but you never really know if that's what made you go the extra ten feet or not.
