daddy_tindell Posted March 30, 2015 Report Share Posted March 30, 2015 Good Evening Everyone. I hope you all had a blessed palm Sunday I took a stab at cutting my first coin today. Turned out OK but my question for everybody..I broke 6 blades while doing this..is there a trick I'm missing? Tension to high? Corners to tight? Feed to fast? Should I be using a cutting oil of sorts? Any advice would be great. Enjoy the rest of your evening. God Bless, Robert amazingkevin, Lucky2 and Scrappile 3 Quote Link to comment Share on other sites More sharing options...
Fish Posted March 30, 2015 Report Share Posted March 30, 2015 Sorry I can't help I've never cut metal. I'm sure some can help though, nice work on those too. daddy_tindell 1 Quote Link to comment Share on other sites More sharing options...
amazingkevin Posted March 30, 2015 Report Share Posted March 30, 2015 Turns that are too fast will over heat the blade tremendously and they will break on the spot every time.Blades should be tight.On the corners try to hollow it out a little before turning that will cut down the friction. i've thought of oil or wax ,maybe even coconut oil but never read anyone using the oils except for manual hand saw cutters.Keep track where you break your blades as that where you need to change what your doing,Slow speed mean less heat build up to.Sometimes i watch the blade go up and down whole cutting critical areas ,that's as slow as you go sometimes. If all you ever cut in coins is these your a master only breaking a few blades(6) perfect work.You will be the one to watch in metal cutting! :thumbs: :thumbs: :thumbs: :thumbs: daddy_tindell 1 Quote Link to comment Share on other sites More sharing options...

merlin Posted March 30, 2015 Report Share Posted March 30, 2015 When I cut coins (not that often) I use metal blades. OK all blades are metal OK start again...FD-The Iron Man Blades..I found the jewler blades to fine. I kept breaking heaps of them. Nice cutting all the same. ***Merlin*** amazingkevin, LarryEA and daddy_tindell 3 Quote Link to comment Share on other sites More sharing options...
daddy_tindell Posted March 31, 2015 Author Report Share Posted March 31, 2015 Thanks guys..will try that with the next ones...hopefully it gets better. Merlin I didn't even think about iron man blades...that is an option too. Quote Link to comment Share on other sites More sharing options...
Lucky2 Posted March 31, 2015 Report Share Posted March 31, 2015 I'm sorry that I can't help you out with any tips on how to cut coins, I've never tried doing that. I find money is hard enough to come by, I'll be darned if I'll start cutting it up. Len wombatie 1 Quote Link to comment Share on other sites More sharing options...
Jennifer Moon-Child Posted April 1, 2015 Report Share Posted April 1, 2015 Wow, that's pretty cool. I have a bunch of foreign coins that are basically worthless that we inherited from my husband's mother, and I bought some Iron Man FD blades on a whim last time I ordered...Might have to give it a try, though I doubt my attempt will look anywhere near as good. daddy_tindell 1 Quote Link to comment Share on other sites More sharing options...

Can't complain bout that. Wow, that's pretty cool.

I was actually very surprised at how easy it cut...with the exception of blades breaking so much...you should give it a try I like your cuttings and the information here.

Scrappile Posted April 1, 2015 Report Share Posted April 1, 2015 Looks like you got a great start at it. Something I've wanted to try some day, like so many other things. What do you hold the coin with while you cut? I've seen a few homemade jigs for that purpose. daddy_tindell 1 Quote Link to comment Share on other sites More sharing options...
bonacker Posted April 2, 2015 Report Share Posted April 2, 2015 Definitely use metal cutting blades. I got mine from Sloanswoodshop.com. They are not expensive. Some say you can use regular skip tooth blades, but don't believe it. You NEED a coin holding jig. I made one and it works perfectly. Cut a wood block about 3"x3" out of pine, poplar or whatever. Use a forstner bit about the diameter of the coin (a tiny bit larger is OK but not smaller). Drill down the center of block no more than 1/8". Then use another slightly smaller forstner bit centered on the previous cut all the way through the block. You now have a hole thru the block with a shoulder where you will later place the coin. Then drill 2 holes using a regular drill bit from side to side to accomodate 2 bolts long enough to place nut on each end. DO NOT cut these holes through the forstner bit borings! Now cut the block in half perpendicular to the bolt holes and through the center of the forstner bit holes. Drill a hole in your coin for the blade, place the coin on the 1/8" forstner bit cutting shoulder, insert the bolts and tighten them(butterfly nuts are great). Your coin should be nice and tight and you are ready to go! Use a slower speed and a bit of patience. Check out the "Love Coin" cutting I made in My Gallery. BTW, US coin sized forstner bits are available for purchase on the web. daddy_tindell 1 Quote Link to comment Share on other sites More sharing options...

What do you hold the coin with while you cut? I've seen a few homemade jigs for that purpose. I have seen jigs like what bonacker is talking about...I need to make one..a quarter is just a Tish smaller than an inch. So I just drilled a 1" hole in a piece of 1\8 scrap..tape on bottom and on top.. Worked fairly well. Definitely use metal cutting blades. I got mine from Sloanswoodshop.com. They are not expensive.

bonacker Posted April 3, 2015 Report Share Posted April 3, 2015 The Love Coin. 2 necklaces, one for her, one for me. daddy_tindell 1 Quote Link to comment Share on other sites More sharing options...
daddy_tindell Posted April 3, 2015 Author Report Share Posted April 3, 2015 That looks great! How do you attatch your pattern? I've been using double sided tape. Quote Link to comment Share on other sites More sharing options...
bonacker Posted April 4, 2015 Report Share Posted April 4, 2015 Simply spray glue the pattern and the coin. Wait a minute and attach. Cut, remove pattern, clean coin with mineral spirits. Drawing the pattern is quite simple and can be done for any size coin. I did mine for a half dollar. If you don't want to make the pattern, there is a great book called "Scrollsawing Coins,Glass, Metals & More" by Dave Freeman that has it.
