A buddy and fellow-woodworker got here to me with a difficult woodworking challenge – an curiosity in reproducing a Music Stand that was a large a part of his childhood reminiscence. My position could be to create a detailed set of drawings with full measurement templates for his use in establishing the music stand.

His father, a musician, owned an previous traditional mahogany double music stand. It was an necessary and distinguished piece of furnishings within the residence. Unfortunately, the music stand was misplaced to the household. There have been no images, however fortunately he had saved a sketch made by his father a few years in the past.  The sketch, proven beneath, was in pencil on two pages of paper vellum.  It was tucked away for years folded in an envelope, figuring out that sometime this might be helpful and priceless.

As you possibly can see, the sketches have been primarily in perspective 3D mode – sadly, there have been no scaled or straight-on entrance, prime, facet orthographics. Nevertheless, it seemed like necessary dimensions have been proven. This was going to be a problem, particularly the higher half with double angle-adjustable music racks. My regular process for beginning a SketchUp wouldn’t be potential. That is, there could be no imported images or orthographic shapes to hint-over. I must interpret these pencil graphics and construct the elements line-by-line.

I began on the prime of the music stand, the adjustable music racks. I assumed this might be probably the most troublesome portion to develop. Below you possibly can see this primary stage of design – sizing up the elements, however with none joinery. At this stage, I used to be ignoring tips on how to do the angle adjustment with ratchet tooth. I knew the Music Holder Side assemblies could be hinged to the highest of the oblong Frame. I additionally knew the Arms would even be hinged and related to the Music Holder Sides.

These hinged elements could be probably the most troublesome to work out, and SketchUp would assist to resolve this problem. As proven beneath, I arrange a number of views of those elements facet-by-facet and rotated at totally different angles. I additionally added toothed bracket plates to see the interplay with the Arms.

I arrange a Zoom assembly with my buddy, and shared the true-time SketchUp file. I may orbit, zoom, and pan across the mannequin to point out the issue areas.  Online, we have been capable of type out a new configuration and placement of the Arms to keep away from interference.

The subsequent problem was to work out a suitable toothed ratchet configuration and placement. So I arrange one other SketchUp Scene as proven beneath.

With this configuration, I used to be capable of element the feathered form of the Support Rails and design tooth configurations. Here is the ensuing feathered Arm.

Also, I continued working joinery as proven beneath with this dovetailed Frame, and mortise and tenon within the Music Platforms.

Here is the ultimate exploded view.

And the ultimate Assembly

Here’s a quick animation of the Music Stand motion.
