This is an order from a client for a new 12-bore Holland & Holland system sidelock ejector. The gun is being built by hand (not from a kit of CNC parts like Holland gun now are). This is the actioning stage. We should have it ready for stocking in April. Barrels are best 30" chopper-lumps. http://www.facebook.com/photo.php?fbid=5...e=1&theater

Beautiful parts Dig. Being a machinist for many years, I'm interested in how these parts were made as opposed to your reference to Holland guns. Can you elaborate on this point a bit?
Regards
Chuck

These are made from forgings from Phillipsons. filed up by a London trained actioner.
Holland & Holland now CNC and spark erode the parts so that they just need fitting. A lot of traditional actioning work is now being done by machine.
We thought we'd go the traditional route with these guns, just to show what we can do using the methods the British gun trade is known for. We wanted it to be a real, hand made gun.
I predict that in the future, most British guns will be assembled from close-to-form CNC made parts, provided in kit-form.

Shavings and filings on the bench or shop floor are the same, whether done as it was 1903, or with today's high tech- CNC and CAD-CAM techniques. When my late Grandfather did his apprenticeship, you had a vise, a set of files and a Try-square and a block of not rolled steel with the "bark" still on all six sides- and with the afore-mentioned tools and gauge, you had to file it to a perfect cube--Even in my apprenticeship years in Jr. High and High school (1950's) the shapers, lathes with tracers, Bridgeport Milling machines and the top precision tool in his shop- a jig boring machine (Clausing?)- took time to master. I remember when he gave me a blueprint for a circular shape of free machining brass, two 3/8" thru holes at top and bottom of the circle- aprox, 4" OD and .500" thick- then slotted- so I went from lathe )LeBlond) to drill press (Atlas) and then to the Bridgeport mill- when I had it done and checked to print, I proudly called my Grandfather over and asked him to check it for me- "Okay, Sonny--follow me" and he headed for the lavatory- removed the piss cupcake that was plugging the center drain hole in the urinal trough, dropped it over the two locating pins, looked at me and smiled- and said "Yup- that'll do it just right" and patted me on the shoulder--

Very nice! Is there a chance that the construction of this fine gun will be chronicled in The Double Gun Journal?

Dig,
That's super impressive file work. Just to be clear, there were conventional non-CNC mills and lathes used to machine the forgings and all surfaces are then hand-filed to fit and finish?
Thanks

Wow, very cool work.
What did the "action" look like before the actioner started work on it? I would love to see some before and after shots.
Did he use jigs and templates to get eveything right? Or does he just eyeball it?
How long did it take to go from raw to finished?
Thanks for sharing.

Depends whether you have the machine or not!

The owner of a Canadian shipyard acquiring new technology to build destroyers told me 25 years ago if his company hadn't won the contract it would have been out of the shipbuilding business forever. Maybe I'm an incurable romantic but it seems this British going-back to the beginning is the same thing.
