I have in my tool chest the flexible sander to help sand curved surfaces. But for me this tool is too wide. I saw somewhere where someone made there own custom flex sander. So I cannot take credit for this idea. But I gave it a try and made my own. Only difference is the one I made is narrower so it would be more comfortable in my hand and I am able to get into tighter places.
First I bought tubing benders, cutter, tubing and small leather rivets. Tube sizes are 3/16 and 5/32.
Started the bending.
Add CA glue and let it run into the corner to give some extra strength.
Made my cuts to even out the arms.
Clean out the cut and enlarge it.
Cut smaller pieces off the smaller tube and selected couple rivet heads.
Glued the rivet heads to the short tube sections.
Using no glue I just forced the smaller tube sections onto the ends of the sander.
Cutting my own sanding strips.
Add couple drops of CA glue. When gluing the other end I slight squeeze the sander so it can get a tight grip on the sand paper.
Write the grit number.
Sander is done.
Testing it out. Works great.
