No, just before using the CA Paul ..

Paul,
Me thinks you are applying too much ca. When you put it on the blanks it also goes on the bushes and over the gap between bush and blank. We know that ca doesn't stick too well to metal and generally the strongest bond in this scenario is that of the ca on the blank. Normally the ca will snap just proud of the blank leaving a ten second job of removing the surplus by rubbing it on a piece of scratch. If the build up of ca is greater then the glue delaminates off the blank and sticks out like a foreskin! If the build up is like this then it can crack off the blank as well.
That's why I think you are putting too much glue on the blanks. Now this bit isn't contentious at all and I know it won't provoke any response, but I think that a lot of people put far too much ca on their pens.

Quite possible Neil, between 6 and 10 coats. I'll try less next time.
How many do you recommend?

Bob, got plenty of coriander in the garden, how do you turn it?
Dig it up Paul and turn the roots, I'm sure PaulM will have used it, he's turned everything else. I wouldn't dare try it 'cos the missus would kill me.

I watched David Lim's video over at Timberbits Paul, it was this that got me going he uses quite an amount of CA, i don't recall the count now but 20 comes to mind. So when i first started i used to do anywhere between 10/15 depending on what blank i was doing. Today i don't do more than 5 coats. It is up to you the amount you choose there are no set rules, but i can tell the difference between the 15 and the 5, but i am happy with the end result using 5 and i have less lifting of the CA ..

I put three on, but don't dilute it with blo. I sand it with 240 only, and put three coats on. If it's thin stuff it's going to go on thinner! I use bog standard stuff from the hardware store in big bottles for a fiver, can't remember the name and Im not going out in the workshop at this time of night.
However, I put on enough coats to cope with a quick wipe with 240, 320, and 400 before starting out on the 1500 mm (400 sandpaper grit is just more coarse than micro mesh 1500 grit, they are different scales so no point going higher on the sandpaper grits to go back down to mm 1500). Trial and error with your glue and the speed with which you apply it and whether you put blo with it, the purpose of which has long defied my meagre brain.

Glad contentions or claims do not provoke porkies. Wishing remembering out of my schedule.
One coat of CA and other finishes as I see fit. My mate the pro turner for all bowls etc uses a spray laquer made in australia a light coat of Black Bison Polish buffed with the horse hair brush sold by Liberon. After my one coat of CA I use my Liberon Wax stick.
No one has deliniated the various timbers each one deserved respect and understanding IMHO. There is no magic pudding.
I am also having absolute fun with a large tin of Automotive 100% Carnauba Wax. No special bushes cause I undercut mine to allow accurate measurement at the tip, centre and ends how can CA stick to where its not applied. I use med CA and do not panic.
Try my test apply a one coat of CA spray it lightly then turn of the CA carefully itis firmly in the Timber I know.
All the best with your own methods secrets? formulae. Always compare real with real ie two more of the same timbers I finish at 1000 to 2000 grit you finish at 240 say your finish will accept a different coating and respond another way.
In the end have fun.
