    Hi Clinton,
    This is a very clever and creative method that can be adapted to other projects. In addition, the slot cutting jig has given me another idea for how to cut a thin slot without using a surface grinder.

    I'm working on an attachment for my angle grinder that will do crude machining work. The fixture depicted was a quick fix for what I wanted to accomplish. The accuracy was okay for the job. I think the idea could be really improved upon. Keep us posted as to what you come up with.

    Clinton,

    I am looking forward to seeing your angle grinder adaptation “invention”.

    I might be able to use it. I have been watching the videos at the “The Tool and Die Guy” website by Phil Kerner (I became a lifetime member last year). Phil shows a technique that I want to use. However, his tool modification process requires a surface grinder to cut a thin and 0.25” deep horizontal slot into the front face of a typical surface gage (e.g., a Starrett No. 57A). This slot is used for a thin and slightly rounded piece of tool steel to be inserted into the slot and held by friction (high precision not needed but there must be only one high spot along the thin tool steel front). When this type of modified surface gage is used with a test dial indicator, it is possible to very accurately (within a few 0.0001”) test a machined object for being vertically square relative to the horizontal plane of a surface plate and provide measurements for machining (or grinding) to make it square.

    I am looking for a way to grind the thin slot without using a surface grinder.
    Thank you for your posting your ideas.

    Paul

    You've made a difficult choice, not easy to domine !
    The first length of turn models as you made in metal were made in 18th wild parts of America in wood for the rifling of Kentucky or such flint rifles, it is a publication about that published on Historical Armmaking technology booklets.

    I've upgraded the rifling tool somewhat. Slightly easier on the back and the results are substantially better.
