Support Table for Perkins Braille Writer

Make a table to support the paper as it exits the Perkins Braille Writer.

It is difficult to read and correct the braille "dots" as the paper comes out of the Braille Writer. This table provides support for the paper while reading and erasing the Braille dots.

It is particularly useful when performing math calculations on the writer.

I typically supply two tables to each child. One for home and one for school.

Materials: 1/4" Plywood (12" x 20" per table), 3/4" square wood stock 15" long, Paint, Wood Glue, 3d Finish Nails, #6 x 3/4 Wood Screws, sandpaper,

Tools: Hammer, Drill, Sander, Saw with wood blade (saber, table, or band), tape measure, bar clamp (13" or longer), screwdriver, #15 Torx bit, square

The various steps are shown below. These fabrication steps & dimensions are also shown in the attached files

"Build a Braille Writer Support Table.pdf" and Brailler Table Drawing.pdf

TOP AND INNER DWG.jpg

Cut the table top and inner support plywood

Use the Dimensions shown in the sketch:

LAYOUT1.jpg

Layout the two 5-1/4" x 4-1/8" sides on 1/4" plywood as shown. If the table top is thicker than 1/4", subtract the extra thickness from the 4-1/8" dimension.

TABLE SIDE DWG.jpg

Cut out the two sides from the plywood. It is easy to use the first cutout as a template for the 2nd side.

BRACES DWG.jpg

Braces - cut one brace 10-1/4" long and two braces 3-7/8" long from 3/4" square stock or scrap wood. The longer brace may have to be cut shorter is thicker plywood is used for the sides.

Screw the top to the inner support with 4 - #6 x 3/4 wood screws. I prefer Torx drive screws.

Test fit the table to a brailler. It should be level with the small discharge shelf of the brailler. If the table is too high, it will snag the paper. Sand the bottom of the table to make it fit.

Sand all corners and edges. Remove any burrs and splinters. You may need to fill in the screw holes on the stop to make the surface smooth. Recheck that table fits brailler and does not "rock".

WITH BRAILLER.jpg

Paint the table all around. Use at least three coats on top to make it smooth.
