Introduction: Hand-Forged Ring With CA Glue Inlay
Today I'd like to show you how I made this hand forged ring out of the bare minimum tools, most of which you probably already have at home if you're a tinkerer like me.
The inlay is done using cyanoacrylate/CA glue, normally for inlays you would use UV curing resins but these are a LOT more expensive and can sometimes be hard to come by.
Let's get started...
To make this Instructable you will need the following:
- 2mm Bronze rod
This can be found at your local hardware store in the welding/brazing section. I recommend using bronze when learning and then moving on to precious metals later.
- Cyanoacrylate glue with activator
If you have UV curing resin available you can also use that instead.
- Semi-precious stones of your choice
- a Butane/propane blow torch
- Some masking/painters tape
- a Hammer
Any piece of heavy metal with a smooth surface can be used, before I made myself this small jewellers anvil I used an old hammer head mounted in a vice and it worked great.
- Metal polishing compound
- Included in this Instructable is a 3D printable lathe chuck that works great if you plan on making a lot of these.
Step 2: Start Forging:
Now we will need to start shaping our bronze rod.
For this ring you need a rod that is two times the circumference of your ring, mine was a 13cm long rod but I leave about 10cm extra to make handling it easier
Now we need to anneal the bronze rod, with the butane/propane torch you need to heat up your bronze rod until it gets to a cherry red color.
While hammering you will feel the bronze getting harder, once you feel this happening you will need to reheat the rod as above.
Keep repeating the above until you've reduced the thickness of the rod from 2mm to just below 1mm.
你现在可以继续,删除多余的杆,我use my trusty vintage Knipex cutter.
Before we start brazing the parts together we need to create the gap for the inlay.
Now we are ready to braze the two bars together.
To braze pieces like this I like to use the metal table of my press drill and some old salvaged magnets to hold the pieces in place.
If you have bare silver solder with separate flux you can now apply some flux to the end where the two bars meet, if like me you have flux covered silver solder rods I like to heat up the piece that needs to get brazed and then rub the fluxed rod over it to melt some onto the piece.
Step 4: Shaping:
Start bending the piece around so that the ends meet, if you find it difficult to bend you can wrap some pliers with painters tape and use them to bend the piece.
Now like in the previous step apply some flux and heat up the joint to make the solder flow into it, if there is not enough silver solder to fill up the joint add some more just be careful not to let it run down the side.
And now you should have something that's starting to resemble a ring!
Step 5: Roughing It!
We need to now make our ring round, if you have a ball point hammer you can place the ring over the sphere and gently hammer it until it is round. Otherwise you will need to put it on your anvil and gently hammer the high points until you get it as round as possible.
If you have a Dremel it makes this next part a little easier.
After rough sanding is done we can move onto the inlay.
Step 6: The Inlay:
To do this I used the cap from an old spray can (I always keep these to mix things like resin in instead of using new cups) and add some beads, for this ring I only used about 3 beads.
Then using a nice and heavy hammer I started to break them down, how much depends on how you want your inlay to look. For this one I left quite big chunks as I wanted it to be transparent with chunks of turquoise in between. But if you want a very uniform inlay you can continue hammering them until you are left with a fine powder.
现在,你有你的好石头的inlay we can use some masking/painters tape to create a barrier on the inside of the ring for the CA glue to pool in while we insert the stones.
Take your bottle of CA glue and squeeze some into the cavity of the ring, you want to make sure you've gotten it into all of the corners.
The glue should harden basically instantly but just to be sure the inside is also cured I let it stand for about 30 minutes before peeling off the tape.
-> It's very important to wear a mask when you are sanding CA glue! <-
Because I used quite chunky stones in my inlay it took a lot of sanding to knock it down even with an 80 grit sanding drum so I highly recommend using a finer stone powder.
If you would like to make more crafts like this in the future I highly recommend you print out one of these lathe chucks bymdkendallon thingiverse.
Step 8: Finishing:
Now that our inlay is done we can start with the final polish.
Next I placed a piece of 220 grit on a glass pane, rub your ring in circular motions to even out the two sides. Repeat with 400 grit.
After you're done with the 1500 grit you should be left with a satin defect free ring ready to be polished.
Now with some felt pads and metal polishing compound start polishing your ring from the coarsest compound to the finest.
When your done with the compound blocks smear some liquid polish onto a soft clean rag and start rubbing away.
Step 9: You're Done!
The last picture is of a ring I made previously with some of the bronze filings mixed in with the turquoise.
