A windmill
« on: January 18, 2018, 09:45:09 AM »
A new year and a new project, this time a windmill to put by the pond.

This windmill is based around the Norfolk Sprowston Mill of 1730. It was accidentally destroyed in a fire in 1933.

Height to the tower top is 605mm (24" approx), sail wing span 712mm (28" approx).

Should look similar to this when it's finished.

1462-0


Plans.

1447-1 1449-2


Start off with the sheet material then cut out the larger sections

1460-3 1453-4

Now for the smaller bits, as you can see there's a lot of them

1456-5 1458-6

Building has started and here's where we are now

Firstly the sails needed to be put together, this is a slow process due to the amount of parts and each part needs a spring clamp to secure it till the glue is set.

1464-7 1466-8 1468-9

Here's a video of a test of the motor for alignment and whether the motor is powerful enough to turn the sails.

It should be noted that this is my addition to the plans as I felt it would be better with the sails turning when the sun shines so I have aquired a 4.5v solar panel and thats what will power it all. At preent it's also a bit noisy so I have to look at using grommets between the support plate and the wooden shelf to try and reduce the sound.

Sails now made

1473-0

Next is to make the base, in the photos below you can see the segments that are created to put in some counter balance stones, help to stop in blowing over in windy conditions.

1475-1 1477-2

The base now well on the way to being completed, now for the roof cap

1479-3 1481-4

Now follows the fiddly bits, the rear stairs and direction sails

1483-5 1485-6

The base has now had its roof painted and the walls have had brickwork paper applied. The paper was applied with watered down uPVA glue then coated with external varnish once dry.

1487-7 1489-8

It took a while to get it to a quiet state but now the final motor has now been installed and tested and the solar panel does turn it

1491-9 1493-10
