Not a good day.

Hi Ron, thanks. I was not thinking straight.

A TD wrench is a thicker, stronger wrench - came with the TD series I believe. I attached a picture of what one looks like.

[quote="microflitedude"]I was taking apart an engine to change out some parts. The cylinder was sticking for some reason, so I held it in a rag and torqued, harder than I should have...

...and of course one you realised it wouldn't budge with a small amount of torque, you heated it up correct?

If I can, I avoid using the cylinder tools provided by Cox. For cases such as yours, I place a baggy over the cylinder, (to protect from metal to metal contact,) and use a small crescent wrench.
Sorry for the damage,
Mud

I stretch a slice of electrical tape on the jaws of my crescent wrench

No, I did not. Another mistake. I thought because it was new and I had removed it previously.... I have tried this method, though.

Thanks Mudhen. Do you close the wrench on the relief then turn?

The reason I did it, was because the piston would not slide off the crankpin. Always had before, I think this thing is possessed.

I have any number of engines which I swear are under Demonic control! I've just had an OK Cub (Front shaft induction) refuse to start in any other way than backwards, front induction engines can't run backwards, t'aint possible!!! Now, THAT'S creepy!!

Hehe, sure you don't have a lefty crank?

Another tip is to put it in a bench vise. I have two pieces of angle aluminum to clamp down onto the engine blocks to keep from scuffing and to hold it securely without movement. What probably happened is that you were wrenching hard with the engine in your hand, and as you applied even more pressure,,your grip changed slighly taking the wrench out of it's proper plane,,and it slipped over or out of the grooves due to this. Using a bench vise, you can set your wrench on the engine and keep an eye on things as you apply pressure.

I reverted back to the old standby of Plasti-dip or some folks call it tool-dip, and dipped two new production wrenches from Bernie in that stuff, for better traction and a less-mar tool.

It's called becoming a junior member of the busted knuckle garage,,but you didnt bust your knuckles on anything when the wrench slipped.

I have one of those wrenches, never knew it was for a Tee Dee! Must be an early TD thing as the .049 and .051 I purchased new back in the 90's came with the standard wrenches. What I wonder is how are you supposed to remove the carb mount sleeve nut with that wrench?

Like PV Pilot, I too mount the case in my vice between thick shop rags or wood blocks to aid in cranky cylinder removal.

I did like the idea of the crescent wrench as opposed to the standard cox tool, I wonder what the actual size is as I would prefer the proper wrench over an adjustable. Guess I should go find out!

Hope it looks better today!

Yeah I mean if anything that wrench should have been sold with reeds but no a reedie wrench has tee dee bits that the tee dee one did not?

I'm not sure. This one came with a TD .051

Jammed rudder servo

Ouch! another case of the ground being too high!

I don't think the poor little 5 gram servos were meant to accomodate a giggling imbecile doing stall turns.

That looks nasty. At least the NV appears to have survived intact; the rest can be repaired or rebuilt ('cept the prop, of course).

Oh no!

Well like mentioned the engine appears to be ok. The aft fuselage is intact too. I believe that is a good pic for Ivanhoe's elite club........

It's almost back together Andy, but I'm gonna stick some slightly more manly (wing loading even GREATER) servos in this time to hopefuly get it flying a bit more at the weekend.
Positive side of things My building 'skills' are getting a bit of a shot in the arm.


It's my stupidity really Ron, as you can see I put a new engine in it last night so of course I HAD to try it this
morning. Just threw it in the boot of the car may have knocked rudder and damaged servo who knows ..
New engine fantastic though.

The result: A destroyed TD wrench, bent fins on a new head, deformed relief and bent fin on cylinder. I don't know how it got stuck on there, maybe it ran too hot and seized? New, very clean engine.

Just my worthless venting....

I did the same thing not long ago, happened in an instant.

Very true, it's due

and at least..

lol I can imagine that right now "he he he he stall turn he he oh [bleep] the servo is jammed"

Or, offhand remark to onlookers, "That's what you call a spot landing!"

Nah I think it was more a hole landing

Okay then "Hole in one!"
