A project log for misc machinery

well, I wanted to do more machinery hardware stuff, so here we go...

Unfortunately, I had no luck to get a real pirate ship steering wheel, so a crank was made:

The shaft is now straigt again, thanks to a special trampoline-ish technique:

This poor rusty crown nut had to go to get the shaft out. The next hardware store (saturday evening...) got normal nuts only... angle grinder crown nut replica:

Hmmm... welding cast iron may or may not work, fortunately it worked ok-ish. There is enough threading in the lower part, so the remaining slightly offset threading was grinded down and the broken-off part TIG-welded in position, material outside the allowed dimensions (needs to slide in rails) grinded down. It is important to not let mechanical stress build up during the weld process (thermal expansion...), else it will just crack again. Fortunately, the broken off part does not handle too much mechanical load - with a longer screw reaching all the way down through the lower part, it is clamped in place.

(result not shown, forgot to take picture and looks way too ugly ;)

More disassembly, cleanup, reassembly etc. later:

This thingy acts as addition to the fix of the previous owner for the broken off iron cast part (two big screws to hold it 90°)...

it allows alignment in the fixed 90° position:

aaaand the 45° position (or anything else non-90°-ish) works now again :)

Electrics are installed and working.

aaand, it works :) ok, hand-cranked mode and dull blade:

Todo (prio/time low to high):

- 3. cooling fluid pump arrived. power supply needs capacitor bank.

- 2. belt / wheel should arrive soon.

- 1. broken off part of sawblade mount fix (cast iron again -.-) might just build a support bracket:
