I'm installing an over the range microwave (Frigidaire) and wondering how to do the paper templates. Hopefully someone can give me some pointers. I have the back wall template in place. Pretty easy, no big deal. The upper template, according to instructions, needs to be cut to fit flush up on the underside of the cabinet (there is a small trim piece going all the way around the underside where the top of the microwave will sit). It's the cutting the template that gets me. It seems that I CAN cut the sides and the front of the template, but the back (wall) side of the template should NOT be cut because that will affect where the holes are. Any pointers on this? I was also thinking that I could sit the microwave on the wall plate, go ahead and screw the bolts in about halfway on top, put some caulk on them, and then push the microwave up to touch the underside of the cabinet and drill the holes where the caulk touches. I hope this makes sense, please let me know if you need pics. Many thanks!

I know I'm doing this the hard way and everyone else would just buy a replacement roller brush for $20 but I decided to rebuild one of the end caps of my Aerus vacuum roller brush (about 20 years old). The plastic spindle broke in half so I cut a piece of UHMW-PW rod and attached it in a hacky way. It broke after a couple of minutes of use, right where it enters the bushing in the brush. Instead of trying to more closely duplicate the original parts (not sure what I'd need to improve anyway...maybe the spindle should be nylon?) I'm thinking of getting a ball bearing to replace the bushing that came with the brush. What do you think? Do any roller brushes use ball bearings instead of bushings? It would be an improvement, right?
