Heck, Paul! That's a darned shame at this stage in the build, but no doubt you'll get it sorted.
It's the 'fiddly bits' on this kit which are holding me back, until I see some marked improvement in the articulation of my hands and wrists. Messing-up one of my own models I can live with (I'd curse, but I'd live with it!), but messing-up a model for someone else I just can't risk, or accept. Hopefully, this 'stiff and sore phase' will pass, and I'll be able to get back to it.
