Fortress Construction Update

Plan A

Well I cut out the paper template and then proceeded to carve the polystyrene. As many of you predicted, this led to ‘rough edges’ due to the nature of the material.

The side that the template was on wasn’t bad.

Template side: I left the ravelins until later

But the other side was as rough as a badger’s arse.

The fact I'd not cut out the ravelins makes it look worse than it probably is.

In one respect this isn’t a showstopper because the polystyrene sheet at c.2cm is much thicker than I need and the rougher bits can be carved away.  But that is a lot of work. 

Plan B

Before I went away on a project I found and ordered a thinner sheet made out of a different material that looks like it is less likely to suffer from the bobbliness* of expanded polystyrene. * that’s the correct technical term by the way. 

'XPS Board'.

This is produced for underfloor heating and comes in sheets 6mm thick. One sheet was c 5 quid for more than enough to layer up. One layer will do for the glacis level, one up from that will do for the ravelins and one more up for the bastions and curtain walls.  It's easier to show than to describe......

Cross-section Plan B

The issue with this method is that I might need to draw a new template (the original will probably tear when I unstick it from the polystyrene). And I might need different templates for each layer OR use each layer as a template working up from the bottom.

This is where a potential Plan C came to my attention. I think it was Neil who found a supplier of ‘Vauban’ fortress pieces in different scales. My issues with this option were (a) that the geometry of the bastions etc was limited and not suitable for the dimensions and angles I wanted, and (b) the website for the e-Bay seller was difficult to navigate and work out what the products were exactly like . Then last week another blog (sorry I forget which) showed some products from another company. They have options for different bastion ‘angles’ and the dimensions are close to what I drew on my template.

I’m hoping to see some samples on Saturday at Broadside which should help with my remaining questions. Plan C could turn out to be much easier to execute than Plan B. In a way that would be a shame because I was finding the ‘self-build’ route satisfying. But at least the XPS board could be turned to other uses, like trench lines where the little guys can actually be below the surface of the table!

We’ll see.

If you’re going to Broadside on Saturday and would like to say hello let me know through the comments.

A bientôt mes braves.
