[Stoves] Malot-blower / unboltable low-tech-bearing

[Boll, Martin Dr.]

Paul (A.) and other low tech interested,

 

Proposal for a very easy to make simple bearing where the shaft can be taken
out of the bearing:

-I remind that a nail in centre of the Malot-shaft rotates in the bearing,
not the wood-shaft. This reduces friction and fixes the rotor in axial
direction.-

 

To see the principle of the bearing I mean you understand simplest by doing
first the following:

1. Put two nails parallel on the table with a distance of 3 millimetres.

2. Put a 3rd and 4th nail crosswise onto the middle of the fist two, both
with a 3mm distance as the first nails.

3. You see now a rectangle, made by the 4 nails. This is the type of
"bearing" I mean.

 

To do this for work/real:

1.+ 2.  Place in a wood-plank two nails left and right in the distance to
take the "shaft"-nail in between to rotate easily.

3. Put a third nail so into the wood, that you can bend it down, to form the
"bottom"-part of the bearing.

4. Do so as 3. but bend the nail in a distance to allow the shaft-nail to be
covered crosswise (above the bottom nail) 

This nail can be turned in the wood to give the bearing free, or lock it.

5. Bend the top-end of the nail in 90deg upwards, to have a handle to turn
the nail in its hole in the wood for lock and unlock the bearing.
