Wow Sean, you are making great work, mate...!
I may be wrong but, I think that is the first pen I saw made with my Colonial Red Gum Curly and you fir and finish are very good, indeed...!
CA is well known to play havoc with many people, the fumes it produces when used are in fact a nasty toxic devil, I don't think that the accelerator would irritate you nose more that acetone would but, don't quote me on that, I'm not going to be surprised if one day someone finds out is as toxic as the CA fumes are.
CA sawdust from sanding is equally a Devil to the lungs, a good dusk mask is advised or, do all the CA sanding in wet and dry system, that will stop any dust.
A simple fan close to you, blowing the fumes away towards a door/window/exit, etc., is one of the most effective defences you have, voiding to bend down too close to the surface you are laying the CA on, that is a big, big mistake...!:biggrin:
Cheers
