See, you CAN teach an old dog new tricks... I didn't miss it this year. Old Stuff Day is the brainchild of Warhammer 39,999 and lives on thanks to venerable hobby blogs such as Confessions of a 40k Addict.
I've decided to revisit the post on how I made my Eldar Farseer on jetbike from way back in 2013.
With the recent release of Eldritch Omens, I've seen a lot of comments wondering about the potential to convert the Autarch to be on a jetbike / skyrunner -- the official model is very old and listed out of stock online. Hopefully this old blog post will help you to try kit-bashing your own model.
