Common people and their beer, hmmph.

What does everyone think the answer to this question would be:

"When drilling a hole in thin sheet metal, the sheet must be firmly held to prevent:

A. the drill from catching in the sheet as it breaks through.
B. the drill from overheating.
C. The sheet from excessive distortion.
D. drilling the wrong size of the hole."

There's nothing in the books about it per se, so after a toss up between "A" and "C", I've marked it as "A".

What's your general opinion?

No, no, I don't believe goats or cats are mentioned in the question ... so looks like "A". Thanks Cooper.

As an aside, put them in the back of the Goanna & took them for a walk down the river this afternoon. They did enjoy themselves, though still don't know if they can swim. They thought the sand was rather strange

Okay ... could someone please advise the general consensus, when torquing head bolts, should they be oiled, or not? If so, why? Doesn't it affect the torquing?

Yes, I know, a sensible, boring question. But there you have it ...

Depends if they answer back or ignore you... If they ignore you, try talking to the manifold.... whilst listeneing to Burning Down the House...by Torquing Heads.....

In most case I like to oil before torqueing, gives a smoother even tension. At times when a loctite is specified you dont oil but the loctite will have lubing properties.

it depends on the application. The manual will specify if the bolts require the use of a lubricant or not.

Loctite and oil are generally mutually exclusive.

Loctite counts as a thread lubricant. (while its wet)

Never thought you'd need advice on talking Panda.........................















OK, back in my box..
