Ok this might be posted in the wrong spot but I wanted to share this. I had done a scroll saw project and it had some tight spaces that needed to be sanded. I was irritated after breaking several Popsicle sticks with sand paper glued to them and then my hand cramped up and I thought there has to be a better way. Later on in the day i was cutting up my Christmas tree with my reciprocating saw and it hit me. I could take one of the old blades grind off the teeth and attach sand paper to the blade, I could then stick my reciprocating saw in my vice and let it be an electric sander. Well I tried it and using a slow speed it works great. Just remember when grinding the teeth you don't create a sharp edge on the blade. This worked very well for me, I am sure it is not necessarily the safest way but it did work great and gave me fantastic results. Just wanted to share this awesome power sanding tip to get into small places.
