Now you say about the kits & bushes I realise the bushes I had trouble with & had to get machined out were from the same place as your kits & like you I had to remove the bushes with pliers when I'd finished turning the pens.
I also noticed that the plastic bags they came in had Axminster bar code stickers on them & compared with TB they weren't that cheap either, oh well lesson learned.
That said you've still pulled the rabbit out of the hat & produced 2 lovely pens
