Trondster,
I really want to thank you for your cooperation on this topic. I made an account just to thank you and tell I successfully converted my DM10 to an all new mesh head kit. Your pics where extremely helpful, since Hellfire's video is extremely low quality and overall, I prefer text and pics over videos.
Said this, and with the hope I may be helping somebody who is in the conversion boat, I would like to point out the following:
In one of the 8" pads, I screwed it up and when assembling the jack I cut red and yellow wires with the bolt when fastening. This is easily the most critical step of the conversion. And may I suggest a change? Do not put the rim prior to soldering. Just turn the sandwich upside down while holding it with your hand, solder, and then turn it the other way, stretch the cables so you are sure they are not tangled on the base and you can keep the screw holes clear.
Also, why cutting a slit towards the center of the funky foam, when you can just make a hole and pass the wires trough it? This way you may have more control on where the cables lay.
I have also seen that you dampened the cymbals with Evans Soundoff, which I also did and follow your advice. Clicky noise is something of the past now, but my ride has lost too much sensibility and I have to hit it very hard, and it continuously cross talks with the bell.
Thanks again for both tutorials and glad to answer if someone has any question.
