I aggree with you there, definatly more then one way, and repair brings all kinds of brain teasers around, so It is always a learning experience, the same thing that made me curious as to how you deal with this, and if It would defeat the purpose if It needed faced. I guess you still have the pin/insert aligned, and that is definatly a good thing, possibly that may be worth It alone, but like you said not everything is always perfect. The other method is'nt either, and sure has it's share of problems.
I would rather use the old ring work also If It was not cracked, and still usable. Time is always a issue as you mentioned, so another reason I asked you about It. I don't think I've plugged one yet, but have bored and sleeved them, and tapped a new insert, so your method is interesting. I aggree phenolic is tuff, and does'nt chip out the same, but I was refering to the older plastics that are common in some older cues. I have had quite a few joint refinishing jobs where the edges of the rings were chipped out pretty badly, and they really needed refacing anyway, I saved as much as I can with the use of finish or By resleeving a piece, but usually needs atleast a slight facing job afterwards. I love to avoid having to reface, but sometimes there just seems no way around It. Luckily in alot of cases It's solid black, making lining the ringwork up a non issue.
That would be the advantage to what you mentioned if the donor was in good shape, because the pin would automatically line up and save you alot of matching work, and I guess I can think of a few ways to add a piece, and reface it to where it bumps back inline, but I can help but think about how when that glue gets on the middle part of the maple, and needs slightly faced, that It may put you just slighlty out of line on the rings anyhow. Sealing the joint and facing may help I suppose. Guess I just need to try it sometime to see. I will definatly pay attention to that the next time in case the donor is in that good of condition. Usually when I see something like that, the ringwork or faces are not that great, and ocasionally the insert might have an extreme amount of slop in It anyway.
The sleeving method you can kind of set It just ahead of where you want it when glueing It up, and just bump the face in slightly to line them up, but the pin centering can cause some issues in some cases as I'm sure you well know, and that's why you struck My interest. Does'nt matter if you tap the insert dead on, if the butt pin does not match perfectly with the new insert (and most times they don't) then It takes quite a bit more time and effort.
Anyway, Your dead on that not every thing works perfectly for every situation, I've definatly been witness to that so far Myself, so this is another way of attacking the ringwork for me, and I apprietiate you sharing. I 'll have to give It a try next time I get a good donor for It.
