Claudio
I am about to mount the back. I found out there is a very tiny (about .3 mm)opeining between ribs and plate due to cross borderline during hollowing. What I should about it?

My thought are:
1. leave it as it is( I do not think leaking is any problem?)
2. using glue to seal it
3. using tiny maple pad to seal it ?

any thoughts will be much appreciated

Solution 1 should be good, if the opening remains too much visible fill it with a small maple pad.

Thanks Claudio.

I mounted the back Sunday night, removed the mould last night. the tiny opening hole seems ok at this stage.

Should I remove the glue in and outside of the box? How if the answer is yes?

try to use a scraper and a chisel, but with a very light hand.
It seems that you are using a highly concentrated glue, also! When glueing the back or the top you can use safely 1:4 or something more hide glue concentration.

Wah, this is the first time I ever know I could use the ratio of 1:4 for the hide glue. I definitely use that for the top. How about later on neck and fingerboard?

Claudio, could this too thick the glue affect the tone? and what do you suggest for inside coating? that is to say what kind of coating you will suggest?

For the neck you have to use a more concentrated glue 1:2 or 1:3, for the fingerboard 1:4 should be good.
Don't worry, the thick glue won't affect the tone. For the inside coating I suggest you a well diluted hide glue 1:10.

Claudio, do you always coat the inside with dilute glue? Do you ever use glair (eggwhite) or anything else instead? Do you ever leave it uncoated?

I was taught to leave it uncoated, but since I was also told to wash the excess glue off with water (instead of scraping it), much of the inside would get VERY dilute glue on it, inadvertantly.

I use diluted glue, never left it uncoated or used the glair. I think the hide glue is a good substance to protect the wood. But some violinmakers use to leave the inside completely uncoated, because the wood oxidizes fastly.
