Minor progress to be certain, but the wheels are still turning for this project on my hobby table...
Here is my brilliant (?) idea - pictured above is a Redoubt spearman with his weapon. Lead/pewter spears can be a pain to straighten (and keep straight), so I thought that it might be nice to replace the shaft with brass tube. The tube is nearly the same diameter as the spear, and would stay straight, while the interesting spear tip and butt would be added to the tube. This would require a hole to be drilled into the spear tip so a length of brass rod could be glued in, and the assembly could then be glued into the tube:
Here is the procedure party of the way through. This is the easy part.
The result! The first two spears were made without a problem, but on the third I encountered the defining issue - the spear tip is not much bigger than the drill bit used to bore it out, and with one slip I put the drill bit into my finger. So, further thought is required.
Also shown above is the inside of the huge Redoubt Figure-8 shields; lovely. The Eureka shields have no detail on the inside.
The pic above shows the options I have come up with so far - my brass composite; a spear purchased from Footsore; a piece of plastic rod that I shaped into a crude likeness of the original Redoubt spear; and a piece of steel rod that could have a spear tip added.
The thickness of the original spear, brass tube, and plastic rod seem to be a bit thick for my tastes. However, the Footsore spear is too plain in my eyes. Decisions, decisions.
