My pistons have some sharp edges. I was thinking about deburring them by hand with some sand paper. I did a search and saw where Shawn deburred his with a dremel, I am a little nerveous about taking a dremel to my pistons. Please school me on this:)hand

Shaun took a dremel to them to smooth over the domes. If your talking about the domes, thats fine, just do what he did, and take your time. Do not get in a hurry. If your talking around the pin bores, or the bottom of the skirts, oil drain back holes, you need a deburring tool or a small fine file set.

if your dropping them in on a fresh cyl bore, make sure to debur the bottom of each cylinder too;)

Some years back I used #800 wet/dry on a set of TRW domes, took just about all night, in the garage, sitting on a bucket, listening to KLOS, nursing a Coors light, looked very nice when the job was done, I was told no power tools.

Anyone can pedal a bicycle, can you pedal a flat?????

It's always a good idea. I usually spend no less than a half hour on each piston before they;re done. If hand fitting to a chamber, a lot longer than that.;)
