Reticle Guide for Ruler Quilting

I made the pencil guides to help Mary design ruler quilting patterns, but sometimes she must line up the ruler with a feature on an existing pattern. To that end, we now have a reticle guide:

Ruler Adapters - pencil guide and reticle
Ruler Adapters – pencil guide and reticle

The general idea is that it’s easier to see the pattern on paper through the crosshair than through a small hole. You put the button over a feature, align the reticle, put the ruler against the button, replace it with pencil guide, and away you go.

The solid model looks much more lively than you’d expect:

Printing up a pair of each button produces the same surface finish as before; life is good!

  1. I would have done a 3 x 3 array of the mix, but that’s just me. (Remembers playing Tic Tac Toe at the AT&T exhibit at the Museum of Science and Industry. Using a telephone dial as the input device.)

    1. Dang! You’re right: the marketing feature list lacks a “multi-function tool” bullet item!

  2. I’d be tempted to do a two-in-one version with a center ring (for the pencil guide), an outer ring (to establish the distance), separated by spokes (to allow visibility of the layout pattern).

    1. I like it!

      The first intensive test under field conditions comes up on a few days and we’ll see how they work. If the user community requests changes / improvements, that’ll be part of the proposal …

  3. Given my new infatuation with lathes, I might go for a version turned from clear acrylic with engraved cross hairs on the bottom :)
    There would be much waste material compared to printing, but that goes with the territory.

        1. The user community was unanimous in its rejection.

          However, I just scored a digitizing sight on eBay for a small fraction of the going price … [evil grin]
