Tone Bar Extension
Posted: 20 Dec 2022 6:32 am
This forum has given me a wealth of help on learning how to play the Lap Steel Guitar so this is my little contribution of giving back. For a lot of you this may not be a problem but for us older people learning to play, holding the tone bar can be a challenge. My hands as I grew older became dryer and don’t work quite as well as they used to. Putting lotion on my hands did not seem to work well enough and a bit of arthritis did not help the situation. I tried both the round nose bar and a couple of the others like Lap Dawg. At best, hard to control because of slippage. I could not lift the round bar off the stings because of slipping out of my fingers. As a retired machine designer, when you have a problem you design something to fix it. The pictures show what my final design solution was. I chose a 7/8 x 3-1/4 inch (22.23 x 82.55mm) round nose bar (that was one that I already had) for my design. I thought it might be too heavy but with the Assistant Cover (don’t know what to call it) the weight was conformable and easy to control. I used a 3D printer for the different profiles, testing and final design. I found early in the designs that I needed the indent for the ring finger to be slanted down towards the end of the unit.
I am not interested in making and selling these, I want to spend my time playing the Lap Steel but I would be happy to send anyone the files for this. I just need your email address. I would also welcome any comments or suggestions, good or bad. The source file is an Autodesk Inventor 2014 (.ipt) file and the file for the 3D printer is a stereolithography (.stl) file. The design build volume is 38.9 x 27.1 x 60mm. I think the length would need to be shorter for tone bars of shorter lengths. The thickness between the fingers and the tone bar is 3mm
