Building a TRS Scottish Pistol (?)

[Rudyard]

Does that work like a wheellock sear?

Dear Sam. No it hooks after going through the plate its the half cock position .When pulled to full cock the short end of the scear is' see saw' like & flipped into the full cock, the trigger pushed backwards not up . It seemed a favorite of the Scots (Got to love em ) but then they sell Haggis in fish & chip shops so it might account for it .

Hi Rudyard, Sorry I havn't been in touch recently. I will get back on line and come clean.. now 90+6months.O.D.

Dear Old Dog 90 plus is a good innings Ime near 80 but Ime getting lame .My next door Nieboer is 91 broke both hips & caved his ribs in , but he's as well as can be expected , He wont quit we think wele have to shoot him .
I once recorded an interview with a local woman who had just turned 100 the day before but she was sharpe as a tack , could recall a train crash on a bridge when at school in 1915 she was a Moniter & would go to the rail track to collect any mail hence recalls the whole affaire local carter on the bridge he couldn't reverse so leapt to the wooden bridge edge, the train killed his horses and wrecked his cart. she remembered that clearly. old wooden bridge, the stumps can be seen according to what course the Motueka river takes . Youle be getting your Card from the King no worries .

Oh better talk about guns I've tried to give a Scots Snaphance to the RA but the minions & office bods wanted me to go through hoops & reckoned huge costs .So The curator had to decline my offer what a stupid mess it is so anti gun these days & the RA a magnificent temple to Arms & Armour .
It was offered Sheffield but the Communist's council wailed" No Way !"Even Leeds is close to the Soviet socialist republic of south Yorkshire where they fly the red flag on May day & most others .I voted with my feet. Yet the last shower of NZ leftist dogs posing as a Government brought in stupid anti gun laws want to register stuff even UK doesn't bother with like obsoletes no ticket unless used . Because the Police Goofed majorly & despite gun clubs warning & their OWN bloody laws gave a license to a head case who shot 52 Muslims & they blame us the duly vetted gun owners . P on that! .well that's a gun bit Cheers Rudyard

Does that work like a wheellock sear?

Sam, it is similar to the wheellock sear, but definitely different also. The wheel lock doesn't have a tumbler but the sear operates a little like Scottish snaphaunce. On the Scottish snaphaunce the tumbler lifts the sear due to it's incline shape. There isn't anything similar on the wheel lock, but the sear operates like the wheellock sear as it lifts as you pull the trigger. Here's a drawing of the interior of the Scottish lock:


I don't know if I can describe it any better, that's why I posted the drawing. Hopefully you can see the similarities of the 2 sear bar mechanisms.

Well I spent most of the day making the tumbler for the Scottish pistol. The tumbler has a long way to go yet, here is what's done:



I spent a great deal of time squaring the tumbler hole in the hammer, then machining the tumbler shaft to fit the tumbler. Hopefully, I'll get everything to fit inside the lockplate.

Well folks, "wiscoaster", "Colonial Boy", and "BillinOregon", thanks for your interest & vote of confidence (misplaced as it is), but I'm strictly an amateur machinist.

I took 3 semesters at a JC in 2003 and have a old, used short bed 9 inch South Bend lathe that apparently was used at the College of Blacksmithing & Farriers and a chinese bench mill (it weighs about 350 lbs.) that is about 20 years old now. I took the machining course so I wouldn't lose any fingers and what do you know but our instructor had an industrial accident years ago where he wore a sleeved jumpsuite to work & got caught in the lathe. He lost his entire right arm & shoulder! If you take a string from the base of your neck & pull it down to under your armpit & removed everything, that is what he looked like. But he could do just about anything with his left hand that most people can't do with 2 hands.

I have more perseverance than skills, but thanks just the same guys.

Mike

To continue the aside, safety is paramount at all times, l’ve seen numerous industrial accidents, thankfully all small.
One that didn’t happen was when one of the Army apprentices in the workshop of .which I was foreman, was polishing a bore with the emery paper wrapped around his finger, and the back of his knuckle touching the opposite side of the hole, I spotted this and wondered what to do, if I spoke he’d be distracted, ditto if I hit the stop button, so I lent over and smacked his arm [and finger] clear.
Then before he could say a word I let fly,
‘’You stupid - - - —, if your finger got ripped off there’d be blood all over the lathe and we’ll lose production time cleaning the machine’’
Years later when he’d returned from Vietnam he told me that he’d really resented my apparent concern for productivity but realised that it was a bit of psychology when he came to run a workshop himself.

Hours & hours of filing today, plus machining on the rotary table produced this:


Compare this photo to the one above and you can see how much metal was removed from the tumbler. The tapered incline on the tumbler was done almost all by hand. As a note the large circular steel piece on the back of the tumbler is used to hold the piece on the lathe & mill and will be removed near the end of the lock work.

later, Mike

Cool thread!!

I wish I had the skill set to build guns.

I spent most of the day making the pivot boss for the sear bar. It's assembled to the lockplate like you'd do for a wheel lock. You cut a hole in the lockplate, square it off and bevel the front of the hole slightly. This is what's going on here:

The sear boss is 5/16" square with a 1/4" square post hole.

I drilled a hole thru the lockplate for a rivet. I see the a lot on antiques, the newer copies use a small screw.

Then you peen the front portion that sticks through the lockplate:


I used a 16 oz. ball peen hammer to peen it over. Then I milled off a lot of the peened material and then filed it to match the lockplate:


I cut a slot into the boss for the sear bar:


That's all for today folks.

Looking good lot of work but your getting there good on you .
