Thanks Gents, I don't really consider raising tutes from the dead to be threadomancy - especially if they help someone who would have missed them otherwise.
I like Jerseydevil's tutes as well. I think he's got the wraith conversions that are pretty ace. I made a "wraithlord", but his are very nice - much better than my own.
MasterDRD: The leg plates are measured in one of the photos above. I believe they are 5/16" on a side when making squares, then trimmed to shape. I've found that 1/4" actually works a bit better, though. Trial and error is the best way to figure it out.
Gorlack: Glad I could be of help - my son's necron army has gotten loads of attention at the local tourneys. It's definitely a great way to go when you don't have the cash to buy the metal models and can look great if you take you time. Unfortunately the pariah project as well as the tomb spyder project have been put on hold until my own eldar exodite army is finished.
When I get back to these conversions I'll start loading new tutorials for you. Keep an eye out.
