Help, Opinions on Hornady press conversion.

[MrBottleneck]

Ok, so I have a Hornady LNL press I use but, I am not a fan of the LNL feature.
For one the is to much play in the system for my liking. You can actually see the die move upward as you run the case with ram arm upward very slightly.
Also, whenever I got to adjust the die it seems I am fighting that LNL bushing.
My solution was to simply get a Lee insert that threads directly in the existing threads once the LNL fitting is out.
The only thing I dont like is once tightened down it only sits on the edges (points) as you can see in the photo below.
As you can see once removed there is a area that is not used that if someone could make a hardened thin insert so, it would go around fitting prior to insertion and then it could rest tightly on it instead of the nut points.
Is there any one you might know or anyone willing to make like a washer/spacer that could rest on the ledge you can see in photo.
Its roughly 1.367 outside diameter and the inside is roughly 1.237 and the thickness needs to be roughly .125. Did a quicky measurement it might need to be remeasured for exact numbers.
OR
Could a fitting be made fairly reasonably that would have that shoulder built in.

I also thought the points on the threaded insert could be made round so, the insert could sit down on the inner shoulder. I thought hmmm how would I tighten it. I then thought if it has to holes a spanner with two pins could tighten it in. Just a thought. Any ideas?

Thanks in advance for the input/suggestion.

Stopped down at a local machine shop today and talked to the owner.
He asked how I obtained the thickness I needed etc. then handed me a custom micrometer (not one you see everyday) and said measure it with this then call me with the figure. He then said come back and it he would have it made. I was gone like 40 minutes before returning.
Went back and walla. He had made me a perfect insert.
Best of yet he said no cost. I was very grateful.
Put it in just now and the fit is exacting. It keeps the threaded insert up off those nut points by a paper thickness and fits beatifully. Bye Bye LNL I say.
You can see the 4140 spacer (kind of goldish tone bushing below threaded insert).
So, if anyone wants to know how to ditch the LNL bushing I know exactly what size spacer/fitting you need to have made

He probably loaned you a depth mic. It has the micrometer top, a wide base and a rod or flat probe......do I get the prize?
You had the idea and he was able to knock it out for you.
