Some more progress on the duplicator. I'm hoping to have it running by the end of the week.
Got the follower mounts attached, dialled in and welded. Gunsmith is doing the actual follower and tips.

Well... some more progress on the duplicator. All done now exept for the linkage between the two sets of clamps.
Off work at the moment (flu) so once it warms up (winter here, Dunedin, New Zealand, frosty start but sunny day) I'm going out to my shed to have a look at the cocking piece mounted sights on my fathers rifle.

I'm also looking at using one of those Parker Hale fold down aperture sights for my 7x57R.
I'll look more seriously once it's actually put together.

Getting there matey!
No flex anywhere by the looks of the photos, certainly impressive work.

http://www.photosize.com/

A webpage offering free photo resizing. Very large photos distort the forums so a photo or image of approximately 1024 pixels or less wide is advisable.

NE recommends LANDSCAPE images be resized to no more than 1024 pixels in width.

PORTRAIT photos should have a width of less than 1024 as the height of the image will need a lot of scrolling depending on the resultant image height. NE recommends approximately 600 pixels for a PORTRAIT image. Depending on its height.

The webpage works by allowing you to select an oversize image, select its new width in pixels, and then the image to downloaded to your PC. You then need to upload the smaller image to a web image hosting site or other net account.




A free site that allows you to resize your photos to a manageable size before posting them on the Forums.

About 1024 pixels wide is a good maximum.

Ok, I'll resize for future pics.

First run of the duplicator
Aaand it was a disaster. Good thing that it was only some cheap Macrocarpa.
Still, a few lessons learnt:

1: Watch your bit to make sure that it doesn't move in the collet!
It had gone about 1/4 inch in the collet before I noticed, with somewhat... bad... results.

2: Find a better way to index the blank to the pattern
One side was pretty close to the roughsawn.

3: Put a 100mm spacer in each end instead of 50mm, at least until die grinder is fitted.
The mounting bar and collar that the router goes into interferes with the faceplates.

The die grinder I'm getting has a long, narrow neck that will put the bar and collar well above the collet and bit.

As it didn't come with instructions, I'm having to learn as I go along. All good fun.

I had a hard climb up that learning curve. I too had a bit move on me the first time, just as I was getting near to finishing. I keep that first attempt hanging on the wall as a reminder.

Take your time, check and recheck as you go!

Make lots of sawdust and scrap wood. You will quickly learn as to what works well and what doesn't. I try to rotate the piece in only the one direction and move the cutter pushing 'against the cut'. This helps eliminate back lash and to compensate for the deflection in my low end rig.

Every time that you do one, it will be a little bit better.

Has the ghost ring been brazed/soldered onto your bolt Kiernan?

Soldered.
I chose to do that because it doesn't get hot enough to mess with any heat treatment of the cocking piece.
Although I believe that they case hardened this part. Correct me if I'm wrong.

Still having issues with the duplicator.The workpiece is flexing at the barrel end of the pattern when the follower is on it, allowing the cutter to dig deeper into the practise piece than I wanted.
My older brother (also a tradesman engineer) came up with a suggestion which we then elaborated on.

He suggested a row of holes around each plate, and door bolts to lock them with.

After some changes:
I'll have to get the faceplates remade, but with numbered grooves all the way around the outside of the discs. A sliding plate at each end will lock into these grooves and lock the faceplates together, the numbering will allow it to be indexed together.

Oh joy.
Well. Local clubs Skeet competition tomorrow.

Are the pics not showing up for you?
I have resized... kind of got told off by the mods for posting rugby field size pics so ever since then I've been resizing.

I think your first ones on this thread were too large (physical size wise), the ones of blueing tank etc look the same definition (& physical size) as a all other photos on this forum to me?
Guess we'll find out mate if you've made them too big again - really well thought out work you're doing there mate, tell us about the bluing tank if you can please?

It's a big stainless pot with a 4ft piece of 6" stainless flue welded to the lid and opened up through the lid. Currently insulated with a polarfleece blanket tied on, in time it'll have proper lagging. (The 'stack')
The u shaped slots at the top are 22mm wide by about 30 deep and the stick is 20mm dowel. Slots in the lid are much the same.
All this sits on a gas burner on its own cast iron stand.

I hang the parts in the stack using stainless steel mig wire.

I use a fume applicator to apply the blueing solution.
This is an aromatic oil burner with a stainless egg cup on top. The ceramic dish that came with it didn't last long...
A small dish of methylated spirits provides the heat to evaporate the solution (I use the aluminium cup off a cheap tealight candle... don't use the actual candle for this, some of the wax only evaporates instead of burning and can stick to the parts and prevent them from rusting.)
It sits in the pot on an upturned fruit tin as a stand to keep it out of the water. Some pieces of 30x10mm wood strips act as spacers for an air gap.

The blueing solution that I used was Mark Lee express brown solution. Yes browning. They both go black when you steam them. Just browning solution goes coffee black not blue black.
And Brownells won't ship the Mark Lee Express blue international...

I found this to be a good instructional.
https://youtu.be/VHyoUF50rF0

The differences in my process are that I use the stack both as the fume applicator/humidity box and steam chamber.
Keep the water about 2-4" deep. This is important later.
Once you've done the first heat cycle, back off the heat but keep the pot just simmering while you card the parts.
Now turn the gas off.
Put a splash of solution (just a few drops really) into the egg cup, fill the meths cup.
Have to work quick here, get it all done before the fumes start to come up.
Lift the stack off the pot. Put the parts back into the stack and the lid on.
Put the stand in the centre, put the applicator on it, light the meths.
Put the wooden sticks on and then the stack back over the pot.
Check through the airgap that the meths is still burning.
This is where the hot water helps, as its steam is going up the stack as well, assisting in the rusting process.

Leave it for 5-7 minutes for the meths to burn out.
Once this is done, remove fume applicator, stand and sticks, start gas burner to get the water boiling vigorously. I leave it for about 30 minutes for a heat cycle.
