One feature of the modelling component of the 40k hobby is conversions. GW and White Dwarf encourage this. The drive to an all plastic mini catalogue is clearly intended to encourage this. GW provides rules to incorporate conversions in a legitimate fame work to unleash the imagination of their hobbyists. White Dwarf (WD) features conversions a plenty as do many 40k web site. Do you convert. Below are 2 of my build projects from some time ago. The chimera with the twin hull mounted heavy bolters and and a turret mounted autocannon come from the Chapter approved vehicle rules published in WD. The Ork gobsmasha is a scratch built vehicle from plans published in WD many moons ago, but was built around the time of the Gorkamorka launch and for use in Gorkamorka. If anyone is interested in which actual WD published these rule let me know and I will dig out the issue numbers.
The picture quality I hope is better than previous blogs as I am running in a new more powerful camera.
