DIY hull trimmer

[Richard Flanders]

Those pics in that forum link are from either Dave Miles or Eric Eis. Can't remember which. I used them to make my 10ga trimmer when I got into that game. I bush the dowel right next to the blade to prevent case mouth deformation and an uneven cut. Get the right angle and keep the blade razor sharp and this method is very fast and precise. You just cannot mix hull types or basewad types in similar hulls or the lengths will not be consistent.
