Wire for Small Tesla Coil

TO THE EDITOR OF The Model Engineer.

DEAR SIR, — With reference to my former query re rubber-covered wire (Reply No. 9,320) for Tesla coil, mentioned at page 515 of The Model Engineer, dated May 28th, I am pleased to say Mr. Pike (the writer of the article) has written to me direct explaining that the primary is built of No. 22 gutta-percha covered wire, and not as stated in the article, and that this can now be obtained from Whitney's.

Mr. Pike was kind enough to send me sufficient of the wire for the coil I am making, and I had sat down to write and thank him for it, when I discovered that he had not sent his address. May I ask, therefore, that you will be good enough to convey to Mr. Pike, in your next issue, if possible, my thanks for his courtesy in writing and sending me the wire. I have no doubt this will also interest your readers, as Whitney's informed me they had several enquiries regarding the same. — Yours faithfully,

W. HACK.
