Hi Ed, I'm a little late to this discussion, but wondering if you've continued to use WNG backchecks and if so your opinion of them now. I've been warned the wires are quite a bit stiffer and this might be a problem if installing on old keys that could crack from the pressure. Also would like to know if you think checking is better than with conventional ones. I'm thinking about using them on a 1905 Steinway.
Hi Larry and all,
I will chime in here since we install WNG backchecks quite often at customer's request. They check very well generally. And WNG's backcheck location jig works really well also, it works so well we use it as a one of three references almost all of our backcheck installs We use the origial position and a backcheck boat for funcintion as the other two references as a sanity check.
The larger diameter wont be the culprit to crack the backcheck block, as long as the holes are drilled the correct size. The correct size is normally the diameter of the wire just above the knurling. If the backcheck blocks are really fragile and ready to crack, you could always replace them. We usually use baltic birch, a high end plywood for backcheck blocks in our new keyset builds. It won't crack and holds really well.
I think the slightly larger wire is a positive thing, the checking is very good for these parts.
Dean, thanks for your very informative and helpful reply!
Best regards, Larry
