Thanks,
I have put the dominants on, I will tune them up to full pitch in the next few days.
I was really useless when it came to putting them on. I took them all off at once - I didn;t get a chance to read the posting.
I don't think my cheap Stentor 1 violin has a soundpost and I didn't seem to crack anything.
The bit that holds the strings fell off (what is it called ?) and I had a lot of trouble getting the first string on as I had to hold this piece in place and put the string on, and catch the ball end under the adjuster.
What a mess !!
