One story. Before the war russian designers made a super tank KV-1. Very big, very strong and slow. There was no crank handle, big starter and big battery. During defence of Moskow driver did not shift down in time driving up a hill, engine stalled, tank stopped. Battle went on.... Cruew had no oppurtunity to walk home and they went to sleap inside the tank. Crew woke up becouse tank moved. They open a hatch and saw 2 german mid. size tanks towing them somewhere. Driver started engine with tranny (tank moved), canonire shot and put the mane gun down to towing them tanks, driver put the ttranny into reverce and towed to captured germnan tanks....

But the war was won with fast small tanks with diesel engines, independent suspention and 5st trannies.... (T34)....

 

i have finally got realy good steel (#45/+Crom) to make a teethring. Round pice of 360 mm diameter and 1" thickness. So heavy.... Had to use my friend's car... Very very old '56 Volga G21.... Shot down U2 pilot was delivered to hospital in this car with drunk farmers.... they concidered him to be russian pilot, he said nothing, they thought, that he was shoked after ejection from plane.... funny!

 

pablo,
you have some of the finest metallurgical scientists in the world there in the Ukraine
#45 steel has been used for U joints for years

welding to the flywheel is going to create spots of brittleness that will crack

cryogenic cooling of flywheel and heating of ring with press on is the best but requires more machining

 

Why would you use a crank handle when you have that huge lever called a prop?

a think called prop suckin

39 liter engines have lots of start up friction
i doubt if a 400 lb gorilla could hand prop an ME

most of these had hand crank wind up spring/flywheel inertia starters or an explosive charge starter that fed into the cylinders.

For last 25 years Ukraine exports more then 80% of steel to USA and EU. More then a half of export goes to the USA.

It is dangerouse. From other side how you can start engine in air at low speed when it is impossible to use air flow to turn propeller.

 

I agree with you, it seem that i have been misled by Air International, a defunct magazine which was a little approximative about airplanes engines; spring/flywheel inertia starter is pertinent I think too, but I have no more info about it, but it's true, first ME 109 had a hand crank, how it work, I don't know. One winter day I've helped a friend to "defreeze" the "gummed" engine before start (is it the correct term?) on his old F-4U Corsair, it's not an easy thing!

 

Ok. short photoreport.

























You can see mi friend working with lathe....




When my aero was taken apart, I replaced bearings in tranny.


Exploded view!!


Then I added new overfill bottle.





I had to drive my friend backup car....




Now all is OK! I'm glad, she is on road againe....

 

beautiful machining job on the new toothed ring

doesn't look like bendix was fully engaging fw teeth on old ring?

no CNC machine with milling head? that lathe is older than I am. uncle has a 1944 lathe with babbit bearings he poured himself and machined out. he set it on concrete foundation and built his shop around it. 12 ft long and weights 8,000 lbs

is your loaner car a Volga? looks like an accident between a '55 Ford and a '53 Plymouth
that's went they built cars with chrome steel bumpers that weighed more than the driver

please make us a .wav recording of the new starter sound?

 

Well, I can record sound with my cel.phone, but *.amr standard.

This car is the first gen. Volga, restyled first time. It is made in 50-s. Previous volga had deer on hood, but this deer was considered dangerouse and dissapeared after 2 years on conveyer. This wolga has 2 sofas, easy to put tobed, later models had 2 front seats like in newer cars. Stock 3st tranny is swaped to 5st tranny like in my aero. But my friend wants to put DOHC engine under the hood.

Lathe is made in 1956. It is called 1K62. Babbit bearings were used before 1941, but german Krupp lathes had ball bearings. There are ball bearings inside 1K62. Later 16K20 appeared in 60-s, in 70-s digitall controll unit (DCU) was available as option. Early models were used p/cards and big disckettes (5 1/4"). Now DCU is connected to PC with USB. Yes, we have 16K20 too, but w/o DCU. Especially for you I gonna make a snapshot of CNC mashine with milling head and big microwave for teeth forgering.

Stock t-ring was 10mm, my new t-ring is 17mm. So bendix is fully engaged now. Looking at many worn t-rings on junk-yards I see that bendix really does not fully engages on many cars, not only ford cars and trucks.
