I have been a somewhat indifferent painter and have been somewhat restricted in the types of figures I paint. As such, there are lots of basic things I don't know
. I could just do trial and error, but as I paint so little I doubt I would paint anything to replace a disaster.
Today I received some Black Tree Design fantasy miniatures. These come with slotta bases.
Do you fill the underside of the bases with anything to add weight? The figures seem a bit top heavy.
I've never found it necessary to do so, personally, but some people do. You could use small lead weights from fishing suppliers stuck in with putty or superglue, r offcuts of pewter sprue if you have any left...
Some sit quite loosely on the base, is a filler glue best to secure them?
Most often, I just use a pair of small pincers to add a slight curve to the tab, so that the center point rests against one side of the slot, the ends against the opposite.
The cavalry have a thin flat horizontal metal base rather than a more vertical bit of metal. This sits on the slot rather than through it. What is the best way to attach these figures?
Now, for these, BTD used to provide a special slottabase with a wide slot that takes up the socket plug (cannot really call it a tab anymore, IMHO). Did you get the nowadays common cavalry base with two narrow parallel slots, akin to older GW designs, or a cavalry base with a large slot that just doesn't fit properly? If the latter, just file down the plug a bit. If the former, either remove the tab and pin, or cut a suitable slot into the base.
Or enquire with BTD to provide suitable bases.
