Looks to be a nice start mate but still in no position to piss on other people's opinions/experience. Seems to be a common problem with people that converse via the internet. If you don't like another persons opinion there are far more polite ways of expressing it. Would you like me to provide you an example??? It's pretty easy to insult people over the internet, gutless too.
Now as to not turn this into a COW ill butt out, hopefully others do also.

Using a rattlegun to install flywheel bolts is bodgy.
I dont care how fast his car is,its just wrong.

And I would have no problem telling him to his face if he did it to my car.

You will need a better explanation than that? What part of it is bodgey?
You know what is bodgy? Half the cars that come into the workshop with dangerous repairs from other mechanics that need to be rectified. Experience is experience, professionals are just that for a reason.

Its wrong because you can easily stretch the bolts or damage the threads in the crank.
You have very little, if any control over how tight they are.
You can easily leave them too loose,too.

Well you know what, more than 25 years of not a single problem says something? And im sure there's more to it than zapping everything up.
Ill leave it at that, im not going to be part of a big whinge. All i was trying to say is that there are different requirements for different applications. That's all.

You are right.
There is more to it that just zapping them up.
Its the reason a torque wrench should be used.
Does he nail down cylinder heads with a rattlegun,too?

WOT is right Jacob.
TQ figures and procedures exist for a reason,
There is no way on gods green earth that a rattle gun will do the same bolt up to the same torque every time, there's too many variables.
Doesnt matter whether its a 200k 9 second drag car or a 2k 90 second Kombi, flywheels experience a shitload of different forces and vibrations and no one is perfect enough to do them with your average rattle gun...
Its an example of pure laziness and a shining example of why mechanics get a bad reputation. If he is getting paid to work on people's cars, it shouldnt matter if her thinks it will be ok, he should be doing it by the book and the proper way.
I dont think anyone is going to agree that its a good method of tightening the flywheel bolts man... because it really isnt.

I'm not disputing anything that has to do with the torque wrench, but there was a certain wank factor to the comment made and i pointed it out. Of course there is a book procedure, there is for everything. Does everyone here torque up each individual wheel nut when they take replace wheels? I would hope the answer is yes, each and every time. I will stand by what i said, it all comes down to experience. Oh and by the way i didnt say the rattle gun was all that was used.

Rattle guns will tighten up to between 90 - 100 ft/lbs, the actual effective torque is almost imposable to measure. Unless you’re required setting is between 90 - 100 ft/lbs, the actual output torque changes with the duration of the output pulse so in this case it will just be an average guess. But then again who has a compressor a with regulator that actually works supplying a consistent 90 psi at the right CFM? In this case you’re back to square one, no idea of torque setting.
I don't often hear a rattle gun on song in an engine builders shop, well at least the ones I visit. Though If I go down to Tempe Tires they have an orchestra of them going , do they build engines too?

You said it yourself when you mentioned other peoples cars coming in with bodgy work done by mechanics, If you have a really bad experience with a mechanic your unlikely to take it back to them, most mechanics have probably never seen a fault.....

Lots of comments on here.... My engine let the little bmc arp flywheel bolts go after only 50km. It only took one big skid to really loosen them. Learnt an expensive lesson.
Even on a mild 202 now, I would use two dowels and the bigger bolts. Why spend big coin on an engine build only to skimp on what is already known to be a weak point on the 202.
Anyone tried doing up the bolts with a ring spanner and hitting the starter motor?

This is what I found when doing an auto to manual conversion.
marks on the flex plate would indicate a rattle gun was used.

never mind how your holding the ring spanner, how are you holding the starter?
