Screw cutting and Sound Moderators

Credit where credit is due. Wildcat moderators, lovely products, fully strippable, every single part available as a spare and always a super cheery service, even on a Monday and most importantly, made in Great Britain. Thank you Alison at Wildcat.

This one was destined for a beautiful Steyr Luxus and although I did the machining a while ago it is only now that I actually got around to taking the pictures (Complete with fluff) Plus blacking the thread. The crown is a 90 degree which I do for all barrels I thread for sound moderators unless otherwise instructed, the reason being the crown is easier to clean and an undercut or 11 degree crown is unnecessary as the moderators keeps the crown protected.

Feel free to argue 🙂

I just noticed the cutters in the picture. We are experimenting with different makes of cutter at the moment for both the manual and CNC lathes and these were one of the contenders, I am now on a box of German manufactured inserts which are  looking good so far.

We have an active policy of buying British first, then European, then further afield if necessary and I strongly believe it is false economy to buy unbranded inserts.

On the subject of machining, this thread was cut on the 1970’s Colchester Chipmaster we have here. The ‘Chippie’ is a manual lathe although we did upgrade it to DRO (Digital Read Out) a few years ago. This lathe is always a delight to use and cuts superb threads every single time.
