 ear rings

This is an example of ear rings that I cut out of copper and steel with a scroll saw.

I have tried a scoll saw and became frustrated with it. You can obviously make it work. What kind do you use?

Marilyn, I have made miles

Marilyn,

I have made miles of cuts in metal using a scroll saw, mostly when I had my sign company and was making metal letters. The bigger ones I cut with the band saw, but much of my work was small stuff that required the scroll saw. I tried a couple different ones, and ended up with a Rockwell Delta with a 20" throat. It's a model that is no longer made, unfortunately, and it is the nicest one I've ever used. It is all cast iron, very rigid, and uses a "C" frame saw arm driven by a variable speed 1hp DC motor. The DC motor is constant torque, using a feedback circuit, so you just set the number of strokes per minute that you want and it naintains that, regardless of load. Using the right blades, it will cut metal from 32 gauge up to 1" very nicely.

I use mostly Herkules jeweler's saw blades in my scroll saw when cutting metal. The so-called metal cutting blades sold for scroll saws simply don't work that well. My Rockwell saw takes plain-end blades, so jeweler's blades work very nicely in it.

I haven't checked out any of the currently available scroll saws to see what looks good, so I can't recommend anything. Just look for one that is heavily made, very rigid, with variable speed and constant torque. The constant torque is important or the saw will bog down at low speeds and break blades.

I have one too. Sweet

I have one too. Sweet machine.
Something died on it and I got a Rigid on sale to replace it.
after a week I draqged the delta out of the recycle pile, tore it apart and fixed it. Runs great again.
Gettin old, can't remember what was wrong.

Gene,I can sure understand

Gene,

I can sure understand you hauling it back out and fixing it. At the time I bought mine, I had already tried two or three others that just didn't cut it, and I was pretty nervous about dropping the six or seven hundred bucks (don't remember exactly what it was now) for the Delta. I've never been sorry though. I've had the thing for well over twenty years now and it still works fine. If it ever gives up on me, I don't know how I would replace it; I haven't seen anything else to equal it. I don't use it much these days, but when I do, nothing else will do the job as well.

It's really a shame that so many of the really good tools are no longer being made, and only mediocre stuff is available at any price. I understand that the manufacturers are just responding to the market, which says to me that people seem to have lost the eye for quality, or the willingness to pay what quality costs.

scroll saw

Marylin,

I will grant that the scroll saws made today are not nearly as well made as the old ones. That being said, if one wants to do any serious production work, it takes a more modern scroll saw.

I have worn out a scroll saw at least once a year for the past ten of twelve years and have used a lot of different models.

So far, the Delta Q-3 and the Delta P-20 have been the best scroll saws for the work that I do. I have been using the P-20 model since they first came out. I really liked the Q-3 because it was a "C-Arm" saw. It was really aggressive and fast cutting. However, it didn't cut perfectly perpendicular to the table so it wasn't great for cutting thicker material.

I also like the fact that the P-20 is belt driven. This allows softer starts than most electronic speed control saws. The Delta saws also have a higher cutting speed than most other saws. The P-20 does have a few problems. The top blade holder tensioner "link" is made out of soft metal that wears abnormally in heavy use. The bottom arm end (on my latest P-20) where the blade holder attaches shredded and I had to fill it with metal epoxy (I guess the arms are carbon fiber or some such). I really need to order a new bottom arm.

I like the Delta saws mainly for the ease and speed of blade changing. I typically use four to five gross of blades per month on a slow month.

If you have any more questions about how I cut metal, feel free to e-mail me.
