« Part 5: Completing the Assembly Part 6 of How to make an Arts and Crafts style lamp shade series no next part

This chapter is the last, but I may add some more information later as/if I develop some simpler jigs or techniques.

Here is a finished shade, walnut with Watco oil and a topcoat of pre-cat lacquer:

I did a smoothing with #0000 steel wool then a rub down with a blue shop towel. The entire part was then waxed.

It is much easier to do all this now when there are no mica panels in the way.

I discussed the installation of the mica panels earlier, mainly focusing on ways to do it and how to make it possible to replace a damaged panel some years down the road.

With the shade assembled, the mica retention along the stiles gets more complicated in that there is no way to easily press in brads or other retainers by squeezing them in with a pair of pliers.
(the adjacent sheet gets in the way)

What I decided to do was make a wood retainer “clamp” that is screwed into place.
It is deceptively easy to make with a box joint blade set tilted to the 23.5 degrees and some scraps of walnut.

The profile is “M” shaped to straddle the stiles and press the mica firmly into the rabbet. Two #4×1/2” screws provide the retention.



For the upper/lower rails, the plier technique works fine since I can span the plier jaws across the rail and get the needed leverage.

I’ve given up on trying to make wood strips that blend in perfectly with the rounded corners of the rabbet and instead just settled on some trips that leave short gaps on the ends.
The long strips (lower rail, 3/8” x 1/4”) use three 1/2” brads pressed through the strip and into the frame. Only one brad is used for the short top rail.

Here you can see the two strips and how they are just short of the corners:

This has all been more of presenting methods and a process versus trying to plan out a project, but hopefully it has been useful, especially if you read through all this stuff 8^)

That’s it!

Thanks for following along!
