Greetings,
We all got a good laugh (at me) yesterday in another thread. Now let's try to make fun of me again..and at the same time, resolve a little annoying predicament that I am suffering.
I already reported this issue here but I could not resolve it.
I am using a Lyman lathe case trimmer with a Dewalt drill instead of my elbow to power the trimmer. I run the drill at about 1/4 of the top speed. That means it will run 1-3 seconds max. Often, when I see material is removed, I run it more carefully so the material does not get in the way of the trimming.
I set the trimmed Case Length between 1.751-1.752 as measured with my caliper. When I chamfer and deburr, it brings the case very close to 1.750 (sometimes 1.7505 or 1.7495).
Of course, often, there are cases that are under 1.750 and the bit just runs on nothing. But I still do a little bit of chamfer/deburr just in case.
My problem now....:banghead:
I need to measure at every 5-10 cases I trim because MOST OF THE TIME the trim length shorten. Then I have to reajust the bit. At first, I simply use the "micro ring") and do a 1/8 turn. But within 200-300 cases, I need to adjust the main ring.
Sometimes, the countrary happen. I need to adjust because the length of the case gets longer. It is very rare, but it happened a few times.
I am thinking the main ring is moving on the main shaft beeing pushed when I resize and have to push in the drill on the case. I tried to put a nut with a set screw in it behind the main ring, but I could not make it work.
Hit me with your ideas now...
Thank you
