M1 Tunnel Ram Top Plenum Volume Reduction with Photos
Tom, FWIW, would you do a little detailing of the work you’re currently doing? A short how to in the outside of the manifold?
There's really not much to it. You just need an assortment of files (two rounds, a flat, and a triangle), some 50 & 80 grit sandpaper, and a glove to wear when sanding, so you don't
wear your thumb out (It hurts). The blue handle file is a really coarse and cuts with ease. I find that I've used the edge of it for tight work a lot. You just file in whatever
direction/ angle that works.
Several of my friend have asked why I haven't used power or pneumatic tools and I told them I wanted more control. It's just to easy to make mistakes with fast cutting tools.
If you take one file stroke at a time you can control the removal process and direction much easier.
It's not hard, it just requires time, effort, and attention to detail.
