The first thing to build is the base of the underpart of the windmill. It is made up of 8 pieces with lapjoints to make a octagon. It is called the ”onder (under) tafelment” The windmill was made off oak and I will use the same material. After making some strips of 15 by 6.5 mm I made the lap joints on the table saw And so I finished the “onder tafelment”

Part 4: De koker

This part of the mill is called “koker” and can be translated as tube. It is part of the bottom part of the windmill and allows the main drive shaft to go from the upper part to the lower part. It also allows the top of the windmill to be turned to face the wind with its wings faced in that direction. It is made of 8 pieces and is held together by the “boven tafelment” and some iron bands. On the drawing are some comments noting that the tube has been replaced at the wrong dimen...

At the top of the lower house of this windmill there is a round flat part where the top of the windmill rests on and that makes it able to smoothly turn the upper part of the windmill into the wind. The part is called “de pannenkoek”, the pancake.The pancake consists of 4 parts that are lap jointed together Gluing the pieces together. In need of some sanding The finished products so far.

Part 11: Making the door frames

11-15-2020 06:47 PM by JobK | 0 comments »

This small mill has two doors. This is done so the housing is accessible even when the wings of the mill are turning in front of the door. There are a lot of these small mills with only one door. Then you need to stop the mill before you can enter, so two doors are handy. The lumber Cutting the lap joints Fitting it together Cutting the beveled ends The finished door frames Mounting on the posts All finished

The “boventafelment” is also anchored on the beams with 4 metal anchors. On the drawing these are placed on the outside. But I want to be able to take the cladding off to show the inside. So I will change the layout and put the anchors on the inside Starting off with some spokes out of a old bicycle Some heat to bend the steel The finished hooks are placed alongside the beams They are placed in a recess so the pancake can sit flush Drilling nail holes into the anchors Drilli...

To add more stiffness to the construction of the housing of the windmill there is additional bracing. These crosses are not in the fields where the doors are so I need to make six of them. Starting off with very small lumber Making mortises in the beams Testing the fit while holding things in place with a rubber band And then adding the cross After assembling all parts I made until now fitting it all together All things fitted in place. Time to fix the parts to there place ...
