WORK IN PROGRESS!!! Files may change any time!!!!
I am looking for a YouTube Real Model Diesel Engine Starter tester as I do not have the budget to buy one for testing. Contact me on YouTube if you have a YouTube channel to video a real life test using a Model Diesel Engine.

NOW IMPROVED and Updated.:=

The "Pawl_Model_Diesel_Engine.stl" ( print with supports and in Nylon, co-polyester or similar springy filament ), it has a plastic spring so should be 3D printed in a suitable plastic. I tried a basic test in PLA but after testing the spring in PLA it stopped being springy enough to latch the pawl.

Model Diesel Engine Starter Anti-clockwise power turn using Clock Main spring
I do not have a Model Diesel Engine to fully test this in real life.*
This is a wind up unit for kick starting Model Diesel Engines.
The power of this one is "Anti-clockwise" turn using Clock Mainspring, when facing the Model Engine.
This should save having to use:-
Battery's and electric Model Diesel Engine starters.
Hands or fingers taking risks and causing danger.
The Clock Mainspring I used :-
The French & German Hole End Clock Mainspring
Height 13 mm Diameter 40mm Force 0.50

After cleaning the supports out of the "Pawl_Model_Diesel_Engine.stl"
There are holes in the:-
Shaft Ratchet Clock Mainspring Model Diesel Engine Starter
and the
Body Clock Mainspring Big Shaft Model Diesel Engine Starter
for M3 x 10 (or 15mm) Button Head bolts to catch on to the holes in the ends of the Main spring use with 4mm washers to keep spring on.
The body parts are designed for M3 bolts * to screw, (these can be drilled to 4mm if some adjustment is required), into the Lid part with a hole of 2.5mm to make threads in of 3mm
The shaft two other bolts are M4*
button head Allen bolts
There are two washers for each of the shaft ends, smooth surface towards each other and oiled.
Small spring required for the main ratchet pawl.
Please see the video's on YouTube this should explain things:-

Note these videos show the Clockwise power model, I think that is the incorrect direction:-
Watch it working dry run. I do not have a Model Diesel Engine to fully test this in real life:-

The "Rubber Turner Clock Mainspring Big Shaft Model Diesel Engine Starter.stl" is for a
RC plane starter insert 30mm x 36mm 20mm inner hole I Have not carried out a test fit so some redesign may be needed. This has holes to bolt on to the Ratchet Lid part..
DANGER be very careful the spring does not come out.
Have safety precautions ready.
Turning_Lid_Model_Diesel_Engine.stl = 100% infill for ratchet teeth strength
Pawl_Model_Diesel_Engine.stl = 100% infill for pawl tooth strength
Shaft_Ratchet_Model_Diesel_Engine.stl = 100% infill for ratchet arms strength and supports everywhere because arms are printed off the print bed
