Twigg English Sporting Rifle

Reminds me of Corb Lund and the Hurtin' Albertans somehow.

I know your hooked, you can admit it. 

[Cody Tetachuk]

Oh, sorry. I have castings from Dysons for Left and Right hand locks. The same ones Cody has. I will eventually use them to make a double. Or maybe use the right one to build a gun based on that Smith gun and sell the left lock. Who knows

  It didn't hit me right away that the original post was misleading, sorry. lol


Cody, how was the porosity in your castings? Mine are, to me, a bit porous. Being the first castings I've bought, I don't know if that's typical or not.

Yes they were somewhat porous. You can see that the inside still shows signs of this and will require more polishing (assuming that it CAN be polished out). The other anomaly is that one lock plate (don't recall which one) is considerably thicker than the other but, in all honesty, don't know if they came that way or if I just took that much more off one in an attempt to mitigate the porosity issue.

This lock has only one lock bolt. the front is held by a 3/8" long 8/32 piece of bolt that is screwed into the plate and then bent forward and filed so that it hooks under a flat screw head of a screw turmed into the stock. works supperbly well.. looks like two bolts on this side but only one on the left side.......... it works. The gun is gone or I would have taken a picture of the inside for you. A little Jerry Huddleston trick!!

Thanks Dr. Tim. There's more than one way to skin this cat!

Here is another variation of a hook used with a single mounting bolt.  The lock shown is a back action lock but the method is commonly seen on front action applications as well.  An advantage of this method is that with a bit of careful filing, a slight angle is made on the inside of the hook which causes the lock to 'suck' tightly into the mortise to the proper depth.

I was noodling that exact idea. By filing a corresponding angle on the tab/hook, as you swing the lock into position, it will draw it tight. Once things are "right and tight" I think I will case harden the  tab and screw to reduce wear.

Thanks for the picture.

Here are a couple of pics of a Vickers lock with the front lug.

Note the foward portion of the lock plate has a sweep section to allow for the plate to slide into place with out binding. it is very subtle

Any chance of image recovery here?

If you want a REAL sparker talk to Bob Roller he'll make you up a "Twigg lock" that will knock yer eye out & give showers a sparks.

I have made no flintlocks since 2019 and have no desire to revive them.There ARE some Twigg locks I made on the Davis Twigg external parts and they may not all be on guns.I bought parts for 10 and then 4 sets were from customers.The last one went to South Africa, When the weather gets warm again I might make some set triggers but no locks and will sell them from this forum only.No orders taken and NO deposits for any reason.

I was thinking about doing a forward hook and retention screw on the Chamber's Late Ketland lock as well.  I found that there is not much room forward of the mainspring, and I'd probably have to make a new spring to get some extra room.

Cannot see any of the photos....are they lost?
Thanks Richard
