Hi CT. I did start looking at the scraper section in blood and gore but gave up quickly. After all you said it wasn't one anyway. Well done to CK and Paul

I’ll take the prize for the slowest build..
Wow, it’s been more than three weeks since the last post... Well, I can blame working away for only two of those weeks so I guess I need to start procrastinating less!
Ok; what I did attempt to achieve was a detailed drawing of the Stanley 69. This is somewhat tricky for a tool that is a little on the rare side; not having one that I can perform measurements on meant that I was reliant on photos found on the interweb. The only constant that I would be able to use is the width of a blade (5/8”) so I spent a lot of time trolling through pictures looking for ones with blades in the shot. And of course, just about every picture I found was an oblique presentation. Fortunately I did find a set from an old Ebay listing that showed the side profile along with an old wooden rule for scale so now I had a reference. By printing the photos and setting my one end of my proportional dividers to the one inch mark on the printed rule with the other end set at exactly 1 real inch I was then able to take direct readings from the photo... providing that I ignore parallax error and the lack of definitive clear printed edges...
Anyway; using this method and a healthy dose of guestimation I finally was able to produce a 4:1 scale drawing:
01FD057F-5DAB-4D63-A5A8-5571BEBB4A62.jpg
The curves aren’t 100% but I reckon I can fix them on the job. Now the major setback I am facing is the construction; obviously the original was a casting and I can’t easily replicate that but I do have a cunning plan... make the whole thing from brass and silver solder it together. I’ll still be dovetailing the back and sides together but the curvy nose shape will have to be soldered... which now means I can’t easily use the SS plate I bought for the sides .
So now that tool will have to wait until my new bit of brass plate arrives.
But stay tuned... there’s more!Nothing succeeds like a budgie without a beak.

Introducing the Norris-ish infill beading tool!
As I said a few posts earlier it was my intention to make TWO beaders; a Stanley 69 copy and a Veritas-inspired modern version. However in the weeks since making that statement I got in touch with my feminine side and changed my mind. This was mainly due to simply not being able to come up with a design that didn’t totally offend the eyes. I am talking “stab-oneself-in-the-eyeballs-with-a-blunt-stick” ugly.
So I decided a rethink was required; and decided to see if I could come up with an English infill inspired version:

Not shown in the drawing is the rear handle; I’m still thinking about how to approach the shape but it’ll come. And the good thing is I have just about everything I need to hand! So; the 69 can wait for the materials to rock up but in the meantime I can make a start on my actual entry piece. Dykem, dividers and scribers are on red alert for action!Nothing succeeds like a budgie without a beak.

I’m becoming more and more intrigued by this build,
Especially now we are reverse engineering with a twist.
Cheers Matt.

Hi CT. I have heard good things about silver soldering. Have you done it before? And I hope Baldric approves

The beginning:
I’ve managed to pit aside a couple of “me” days during this break and started my build in earnest. As you may recall my intention is to make a dovetailed infill beader; originally I was going to kick off with a copy of a Stanley 69 and then attempt a modern Veritas-esque version for my submission. Events conspired against me in that I didn’t order the correct width of brass plate and that I could not conceive how to make the modern version without it looking hideous. So I had a rethink and decided to be inspired by Norris/Spiers/Mathieson instead.
So here are the sides marked out and the lever cap pivot holes drilled:

Once these were roughed out I utilised an old toolmakers trick and silver soldered them together at the tips:

As the sides are identical joining them together this way allows me to shape them and cut the tails together. Here are the tails marked out...

... and here they are roughed out along with a selection of Swiss files and my Vesper square for refining them:

At this point I ought to mention that as an Artificer Apprentice I was trained in precision hand filing and shaping to a tolerance of plus or minus one hundredth of a millimetre. Let’s see if my muscle memory still works after 30+ years!Nothing succeeds like a budgie without a beak.

Not too shabby so far...
These tails don’t look too bad... ok; maybe not as precise as I once could have made them but then again back when I was a teen I didn’t need glasses to see things within arms reach!

Now for marking out the pins; here I just lined up the components in the vise so I could slip my scriber into the gaps between the sides of the tails

And here are the results; again not as fine as I once could have made but good enough for a lazy Saturday arvo!

And here are the main components lined up as they will be assembled:

The rear section will be pinned in place; as the top section is the same width as the back I can’t cut through-dovetails so an alternative method is needed.
And that’s a tomorrow job...Nothing succeeds like a budgie without a beak.

Looks very good Chief ,
Great too see some more progress on planes this weekend.
Cheers Matt.

This is going to be a little gem. I like it!

Spend around 20 hours a week for three months standing in front of a vise being glared at by a grizzled Chief Petty Officer; that should do it! It’s not a skill I regularly employed but sometimes came in damn useful like when I needed to make my own surface plate.
I’m very much out of practice but pretty happy with what I achieved; peening will take care of the flaws on the outside and the stuffing will hide the ones on the inside!Nothing succeeds like a budgie without a beak.

Hi CT. Gotta love some progress. What is an Artificer? I am most intrigued.
