Three Octave Bowed Psalteries

One of the main projects that I have listed this year for Phantasy Psalteries is to develop a 3-octave psaltery.

I plan to start planning and building within the next few weeks. I’ve already decided to use a detachable sub-base that can be used to mount it to a tripod, or removed to play it hand-held. I’m going to try and keep the overall size just under three feet long.

With all of the weight-saving techniques that I already use on my 2 1/2 octave psalteries, I expect the three octave psaltery to still be at a manageable weight—all things considered.

If anyone has any questions or requests for a three-octave bowed psaltery, please email me at: eric@phantasypsalteries.com

Bosch PS30 Cordless Drill Review

I recently got a new toy for use in building psalteries, and it works so well, I thought I’d write a review of it:

Bosch PS-30 Cordless DrillIt’s a new cordless drill from Bosch. It’s closely based on their incredibly successful PS20 Pocket Driver. But this time around, they’ve added something that’s indispensable to me: a chuck.

Having read all of the positive reviews, and having tested it out a few times at the local hardware store, I was well aware that the PS20 is a great drill. But, one of the main features I was looking for in a drill like this was the ability to drive in tuning pins: this meant that it would have to be able to grip the modified tuning wrench shaft that I use, not to mention the substantial torque required to drive in these pins. (The driver bit is simply the shaft of a T-handle tuning wrench, with the handle stripped off.) But, the 1/4″ quick-change socket on the PS20 prevented its use.

Looking at the pictures above and below, you can see that the new PS30 Cordless Drill has no problems gripping my specialized driver: owning to the fact that the PS30 has a 3/8″ keyless chuck.

Bosch PS30 with Bowed PsalteryTo the left you can see how the drill is used to drive the tuning pins into the psaltery’s body. Previously, I had used a much bigger (and heavier) 18v NiCad cordless drill to accomplish this task. Considering that this new drill has nearly the same amount of torque, (driving these pins in requires quite a good deal of torque from the drill), but weighs only 2.2 pounds (!), now I can consecutively drive all 60 pins without stopping due to discomfort or fatigue. (You wouldn’t think of it, but holding an 18-volt, 5-pound brick for a drill can get quite tiring rather quickly!)

Plus, because of the chuck, I can use it for a lot of other odd jobs with non-standard bit sizes: like 6mm brad point, etc. As soon as I read about the release of the PS30, I knew it would be perfect. To me, it really replaces two tools: the PS20, (which thankfully I hadn’t bought yet), and my older 18v cordless drill. (I still have my bigger 18v drill on hand for really tough jobs, but for the vast majority of the time, I find the PS30 superior.)

So, since the PS30 has replaced two tools for me, here’s my breakdown as to its advantages over both types of tools:

Bosch PS30’s Advantages over PS20 and other “Pocket Drivers”

  • 3/8″ Keyless chuck allows you to grip a much wider variety of bits and drivers, you’re no longer limited to just 1/4″ hex shank
  • Two-speeds allows this drill to be used to drill holes much faster than other drivers, as it can spin at up to 1,100 RPMs
  • Develops more torque in low-speed mode than most other drivers in its class: 221 inch-pounds of torque! (Nearly triple the torque of the PS20, and over double the torque of Milwaukee’s M12 Sub-Compact Driver.)

Bosch PS30’s Advantages over Larger Cordless Drills

  • Much smaller and lighter, without much sacrifice in terms of speed and torque: 0-380 rpm in first gear, 0-1,100 rpm in second gear; 221 inch-pounds of torque
  • New lithium ion battery technology can be recharged at any time, (i.e., trickle charge), without any memory effects
  • Batteries stay charged longer in between long periods of inactivity. So if it’s unused for several months, the batteries will still be at full charge and ready to go.
  • Compact design lets you get into tighter spaces that other drills cannot
  • Only weighing 2.2 pounds can signifcantly reduce user fatigue if you are doing a lot of repetitive tasks (I know this quite well firsthand)

This is just about the best drill I’ve owned or used. Since I originally got it, I’ve only had to reach for my bigger drill a couple of times, and that was because I needed the capacity of a 1/2″ chuck rather than a 3/8″. My only other complaint is that it would be nice to have some sort of on-board driver-bit storage. I like to have a #2 square driver and either a torx or a phillips on-board the drill at all times.

It’s Good to be Back

Not that I ever really left, but it’s good to be back in the shop making sawdust again. During the Christmas season, I took a little bit of a detour from making psalteries, and worked on a related project. . .

A Psimple Psaltery: Building a Bowed Psaltery, From Start to FinishEven though I stopped building psalteries, that didn’t mean I wasn’t involved with them in some capacity: I was busy formatting and publishing a new book on making bowed psalteries.

Adapted from the plans, pictures, and writings from the website, A Psimple Psaltery, this book will make a handy reference for builders to page through and hold in their hands while they work on their project(s).

As far as I know, it’s the first book of its kind, and I’m eager to see if the library of congress will create a new subject category for it when they catalog it.

But even so, it’s still great to be back in the shop and generally making a big mess with wood. All of this sitting and typing in front of a computer has made me antsy!
