FAQ Content

In this brief video I discuss how I like to remove the reeded edge of a coin ring in the event of existing knicks and/or damage done to the reeds during the forging process; as well as how to round out the thinner, rough cut side of my coin rings. Props to Dave for “coining” the term “coin ring lips”!

The advantage to using the Rounding, Finishing, and Polishing mandrel Set is that as the ring is held on tightly to the tapered mandrel that’s spinning while being attached to your power drill; it acts much like a small lathe, providing a much more uniform finish to the ring than can be achieved with either hand-sanding, using a nail buffing file, a steel round-file, or even a small rotary tool such as a Dremel.

*** TO BEGIN ***

1.) Determine which size tapered rubber mandrel fits your completed coin ring, and slide the coin ring on to it.

2.) Place the mandrel bit into your power drill and tighten.

3.) Adjust the coin ring until it’s well-balanced with no “wobbling” on the mandrel with your power drill on, and then expand the mandrel by tightening the Stainless Steel Phillips head set screw at the top which holds the coin ring securely in place.

4.) Begin on the outer edge of the coin ring with the coarser 100 Grit sandpaper and work your way around to the inner edge of the coin ring; making sure that ONLY the corner tip of the sandpaper is making contact with the unfinished inner, top, and outer edges of your coin ring to prevent damage to the rings’ detail. Take your time with this step; especially when you’re first starting out.

5.) Continue to work the inner, top, and outer edges of whichever side of your coin ring you’re working on using the finer Grits of sandpaper as you go; finishing with “0000” Steel Wool. You can also use the steel wool and LIGHTLY go over the inner and the outer detail of the coin ring before you either polish it with a jeweler’s cloth or after you’ve put a patina (antique-looking) finish on the ring.

6.) The final step is to use a jeweler’s cloth to both buff and finish-polish your coin ring.

Your coin ring will now have a highly-smoothed, rounded, and polished edge on both the reeded and the non-reeded side that is not often seen on coin rings!

Other materials needed: a power drill, 3 different grits of sandpaper; (I use 200 Grit, 500 Grit, and 1,000 Grit), some “0000” Steel Wool, and a jeweler’s polishing cloth to complete this process. Those items can be purchased from Amazon.com; at a big box store like Home Depot, or any local hardware store inexpensively.

*** SAFETY FIRST ***
- Always wear safety glasses and work gloves.
- Always use caution when working with any power tools and electricity.
- Keep fingers, long hair, and loose clothing away from any fast moving parts.

Description: “How to Remove the “Coin Ring Lips”, Damaged Reeds, and Smooth the Rough Coin Ring Edges”

Description:
　 HY630 is liquid rubber(condensation cure rtv, or tin cure silicone) mainly used for silicone plastic molds, with the advantages of good tensile strength, high tear strength, high temperature resistance, excellent chemical resistance, high duplication times, long-term stability, high durability, etc. This moulding rubber is one of the products with the highest use level in the production of craftwork gifts and its shrinkage is even lower than 2‰. RTV mould rubber and silicone rubber are general called two-component room temperature vulcanization silicone with excellent fluidity and good operational flexibility, easy moulding process, and so on. Add curing agent of 2%-3% at the room temperature, the rtv mould rubber is still operational within 30 minutes,and after 2-5 hours, the silicone elastomer(silicone mold) will be obtained with resistance to deformation, extremely high or low temperature, acid and alkali and expansion. The rtv mould rubber is mainly applicable to mold duplication of poly crafts, resin craftworks, lightings, candles. It is also suitable for fabrication of precision molds.

RTV Mould Rubber Applications:
Plastic molds, silicone soft plastic molds,making molds for plastic toys, plastic crafts, plastic gifts, PU products,stationary products, pavement, and so on. It has a quite broad applications due to its favorable viscosity and hardness.

Operation Instruction for rtv mould rubber:
　 The product is a kind of white flowing liquid . If the customer wants to make large products and large size molds, the mold should be made of rtv mould rubber with high hardness. On the contrary, if the mold with fine and precision patterns , it should be made of rtv mould rubber with low hardness. The amount of the curing agent depends on the actual requirements of the customer.

The proportions and reactions of the curing agent and the silicone are listed in the following:
　　1. Curing agent 1% added, the silicone can still be operated within 2.5 hours and can be demoulded after 6-8 hours.
　　2. Curing agent 2% added, the silicone can still be operated within 50 minutes to 1 hour and can be demoulded after 2-3 hours.
　　3. Curing agent 3% added, the silicone can still be operated within 28 – 30 minutes and can be demoulded after 1.5-2 hours.
　　4. Curing agent 4% added, the silicone can still be operated within 10 – 15 minutes and can be demoulded after 1 -1.5 hours.
