Post by Belliott3 » Thu Aug 22, 2019 8:24 am

Can an original JB wooden coil box be converted to accept later style coils?

I can not answer your question directly but Lang's does list a bare box (you supply the hard wear) that you can use the newer coils in.

Instead of permanently altering an original box, it would be a lot better to have a set of coils built to fit the JB box, but which have the later style points.

Original JB coils are excellent, however. One of the best of the early coils.

Definitely. Have the coils altered to fit the box. Not that difficult to do with the smaller modern condensers. And the points can be shortened on both ends. I've seen them done.

Bill-
I have altered KW type coils for use in Heinze coil boxes and Jacobs Brandow.

It is not difficult, but very time consuming.

I cut the dovetails deeper on the tops and bottoms of the coils to get the right size. Originals Heinze coils will work as the box has no modifications.
