I just spoke to a friend who purchased it, and he reckons its not a sturdy unit. Theses too much play and shake to the unit for those fine details.
I would be most grateful if you could post up a photo of your unit please ?
I've got one Vanda-Lay milling table for Dremel, better than the D but not really sturdy and difficult to adjust.
I published a few pictures about my self made one in a different thread a while ago, I just have to find it and will give you a link somewhat later, because I am out at the moment.
I described the device in some details in the other thread, https://www.shipsofscale.com/sosforums/index.php?threads/mantua-sovereign-of-the-seas-1-78-bashed-to-death-kit-from-janos.1125/page-7 ...but here are a few more details. The lathe is an EMCO Unimat 3 which is perfect for this purpose...
And there is another link in this thread for further info.
