Models
All of the
engines below were machined and built by my Dad (Heller Davis).
Most of the engines are purchased as a rough casting kit and a set of blue
prints. A lot of the smaller parts on the engines are machined
from round and/or flat stock. Some of the engines are machined completely from rough
stock (No Castings) just blue prints. If you think you might be interested in machining and
building a model engine see the suppliers pages on this website. There
are a lot of model engine casting kits available to purchase from
different suppliers through out the united states and even out of the
country all listed on our suppliers pages and we don't get a kick back
from any of these suppliers. We post the suppliers pages to help
promote model building because we enjoy it.
MOST OF THE MODELS YOU SEE BELOW
ARE AVAILABLE TO PURCHASE AS UN-MACHINED CASTING KITS OR SOME SUPPLIERS
OFFER MACHINED READY TO RUN MODELS. SEE THE MODEL SUPPLIERS PAGES
