Whats happening in the Workshop - December 2025
Hi All.
I have some encouraging news.
My caster has informed me he's back online to do casting. I haven't had a lot of personal time to devote to this in the past so 2025 will be the turn around after a thin couple of years. I've given him some molds for the caster to start doing his magic.
Plus - I've started adding some 'body only kits', for some of the bogie wagon varients. Purchasers will have to supply their own choice of bogies. Most look-a-like n scale freight bogies are commercially available by Atlas/Microtrains.
My supplier of brass bearings has confirmed a new caster producing bearings. New order on its way.
Thanks for you ongoing patience and support of my efforts and the scale in general.
Wishing everyone a Merry Christmas and a Happy New Year.
Join us at one of the Boptrackgang area meetings which are held monthly in either Tauranga, Rotorua or Taupo. Come and model, problem solve or chat for a while.
