Anyone tried de - glazing and cross hatching their own cylinders?

this is the tool i have used on many occasions but you will need an internal bore gauge as well to measure the bore + make sure you don't remove to much material

Yup. Not a big deal really.

Zedhead, that cross-hatching hone process is very important and it can be done manually by a particular tool.
The tool has a lot of half inch balls covered with grit protruding from a bottle brush type stem. This tool seems a little fine to penetrate the glaze.

I have found dipping it in "Kwikgrip" or some glue then dipping in a coarse grit is better to attain the cross-hatch pattern. This Cross-hatch pattern is designed to cut into the rings to truly bed them in.

In all honesty you would be better to take them to a specialist who will be able to do the job very quickly and at a sensible price, i would say it's safer to get the 45 degree angle as this will keep enough oil on the bore, different angles can leave you with either too little oil causing premature wear or too much causing the rings to aqua-plane resulting in excessive oil consumption.

Good advise, by the time i have bought all the tools i might as well give to someone who knows what they are doing. I have taken to a local engine shop with strict instructions not to tear the s**t out of it
