Hey All,

Chris - Do ya have room to add one more?

Hey All,

I just rec'd parts today. So, it'll be a few weeks as I am finishing up a batch of Queen Anne's and I have about 60 Silers to build but I'll keep updating here as the build progresses.

Thanks!

Very exciting. Thanks for doing this, Chris.

I am a little stalled on my Siler build right now as we are waiting for parts from the foundry etc., so I had a little time to work on the bridleless project this morning.

After straightening everything up and reaming the main tumbler axle hole it was time to drill all the other plate holes. I have a jig I made with hardened bushings to do this job

Next I like to set the frizzen spring so I can tap all the threaded holes at once. This is the jig I use to set the correct height on the spring and spot it for drilling.

Once all the threaded holes are tapped I like to mill the pans in prep for frizzen fitting. So I set them up in the mill and use a 1/2 inch carbide end mill to get a skim cut on the pans and make them nice and flat.

After that it is time to go heat up a can of soup for lunch, so catch ya later....

Well, after a whole day of filing, fitting, grinding, and filing. And filing.

And filing.....

Starting to get somewhere. I got at least another day of fitting and filing, but they're roughed in anyhow!

Well, only got a half day for this project yesterday. Four of them are pretty well fit. Two to go. Then to the internals.

Nice. I am hoping these updates are interesting for at least a few people. I know most of this is common knowledge to the ALR crowd but again, hoping it is interesting for some!

At long last the plates with frizzen assys are finished.

I didn't take a bunch of pictures on tumbler prep. I can do that sometime if anyone is interested, but it is drilling, tapping, clearancing, smoothing etc. For a project like this, after hardening and tempering I put them back in the lathe and polish the axles with paper. You have to walk the line between cleaning up all the machine marks and going too far undersize on the axles. It also ruins the pretty blue color from tempering, but them's the brakes.

Then I use a cratex type wheel to polish out the mainspring ramp. It makes for a nice smooth cocking action.

Chris Evrard · « **Reply #36 on:** October 21, 2017, 08:00:12 PM »

Got a little out of order here. On this batch I noticed that the frizzen springs are scratching the face of the locks. These springs were not originally intended for these plates so I just clearanced the back of the arm a bit. Try to make it all work freely and look good doing it!

I also like to smooth up the inside of the plate for anything that touches it. After a 180 grit finish I'll use a strip of scotch brite (at top) to knock everything down and blend it in. The result is a nice consistent, smooth inner plate surface. The bottom plate is at the 180 grit stage, the top plate has been scotch brited.

I also didn't go too much into bridle prep with pictures, but once they have been rough prepped, drilled, reamed, countersunk, etc. I'll polish up the inside with a few grades of paper so anything that touches will glide.

Thats all for now!

Thanks for the updates, Chris. I didn't know what a cratex type wheel was and had to look it up. You learned me sumpin new!

Locks are looking good.

Chris Evrard · « **Reply #40 on:** October 25, 2017, 07:14:29 PM »

Hey All,

Got all the "pieces parts" together yesterday for assembly.

Then after much knashing of teeth and.......well you get the idea....

Chris Evrard · « **Reply #41 on:** October 25, 2017, 07:26:50 PM »

This batch really turned out great. All the locks operate nice and smooth. They have plenty of horse power and throw lots of sparks. Again, touching surfaces have all been prepped or polished, casting lines removed as best as I can (I leave them on surfaces you will be putting a draft on for inletting), frizzens have been re-timed, the springs have been relieved so they don't rub against the plate, the sear arm is similarly relieved. The tumblers have been set up to have minimal creep and a clean release. And I'm sure I am forgetting something here, but I'll come back and update if I think of it!

Here you can see the slight relief at the tip of the main spring and behind the sear arm.

Here you can see the nice even space between the hammer and lock body.

Here is quick video of a spark test. We've got a nice shower of sparks!

Best,

CE

Got my lock a few days ago. Very nice job Chris, smooth as silk and really throws some sparks. Got a few more parts to get and the build will start.
