I haven't had time to do much work on the M-10. Trusty, my 16 year old border collie, has gone and gotten himself another ear infection, and so has a bad case of the dizzies. So I've only had enough time to do a little modeling. I've added three bolts to each idler arm, you can just make them out in the picture. I've also glued together the drive sprockets, and started adding the individual links to them.
