Having made the funnel caps, I started on the funnels themselves.
These are made from acrylic tube with a 3mm wall thickness allowing me to cut a shoulder in to slide the cap on securely.
I worked out the rake of the funnels, and using a quadrant, cut the three lengths needed to make the body of the funnel.
Then I unlearnt one of the basics in machining on the lathe by not supporting the end of the work being machined resulting in this monstrosity
So, re-learning this, I cut another piece of tube luckily having not reset the quadrant in the mean time
and made a piece that would hold the end of the tube but allow the shoulder to be machined at the same time.
Here is a tube and the support mounted.
Here they are ready for the next phase. The inside of the upper ends were chamferred to reduce their thickness.
The next job is to add a little band around each funnel where the stays would be attached. Some seemed not to have this, or had a less pronounced arrangement. The funnels were marked up and a strip of .25/.5mm plastic strip was glued around.
The ink has hidden these somewhat, so apologies:O/
There is a gap between the top of the outer casing and the cap on these funnels, and so to help locate and support the caps when fitted, I added four little .5x1mm blocks to each funnel on top of the shoulder.
Lastly, the caps were held in place and superglue was dabbed around the inside of the funnel.
Almost complete, these just need the pipes etc to finish them off. I will do this once the hull is ready to receive them
