as soon as I opened my mouth, he was all over me
Hey buddy, love the accent
Similar thing happened to me. Although my son in law is an aircraft engineer his speciality is control mechanisms so he's involved with computer programming and the like, not so much the nut's bolts and hammers and screwdrivers. Consequently every time we see them my daughter has a load of mechanical "stuff" waiting for me to "fix". I love doing this as we don't get to see as much of my daughter and her family as we do the boy's and theirs and it reduces my guilty feelings.
Anyway, on one of our trips to Southern Maryland I was presented with their Briggs engined lawnmower and the story "it shakes all over the place Dad!" Of course she'd managed to hit something pretty solid with the blade and it had put a small bend in the nose of the crankshaft. It's an easy thing to do and my boys in the gardening squad did it from time to time so I got used to straightening them.
Although it annoyed me the first couple of times they did it I actually learned a lot as a result. I used to do all the repair and maintenance work on our machines so was well known at our local repair shop (Melvins in Corstorphine - now long gone I'm afraid) I got to know the owner well and because, when i was new to the job, we had bent a few shafts I asked him if he could get me a straightening jig at a discount. He, very kindly, showed me how to straighten a crankshaft with a length of scaffold pole. Never hit it with a hammer as you will likely damage the mains (especially if they are ball or roller races) and you may induce cracking. You also have to know when enough is enough as a badly bent shaft is likely to be cracked so dangerous if you straighten it as it may snap in use. The fellow round the corner - he of Mk1 Corvette fame - lent me a length of stout pipe so that sorted that!
Unfortunately the cast blade boss had fractured and bits were missing so I went down to the nearest big Lowe's to buy a new one and get a service kit. Although I found the plug, air filter, engine oil etc the place was so big I couldn't find the boss so asked the lady who was shelf stocking. She was extremely knowledgeable and got it for me in no time. Do I just go to the checkout with these I asked? You can, she said, but it's quicker if I do it at my desk over here. After I'd payed and thanked her for helping me I turned and started to walk towards the exit when she said "Can you spare me a moment"? I wasn't in a hurry so I said yes whereupon she grabbed a couple of the other assistants and turned to me saying "could you just say something?" Well yes said I, what would you like? "Oh anything", she said, "I just love your accent and I want my friends to hear it"! I found this quite funny actually because down in Southern Maryland you hear a southern accent often and this lady had quite a pronounced one.
In fact I don't think I have a particularly broad Scots accent but I noticed people would quite often turn round and look at you when, for instance, in a queue (line as they say) you place an order, or actually any situation where people were close to you. Mind you both where my daughter lived in Maryland and where my sister still lives about 2 hours west of Boston it's pretty rural and there aren't all that many Brits, let alone Scots, around.
Ps. I wouldn't straighten a shaft more than once and even then only if it was only running a little out of line. A lot of repair shops won't do it because they are too frightened the shaft will fracture in use. Also, unless it's a machine you know, whose to say it hasn't been bent before? So I wouldn't do this to any other than my own machines. I'm sure a blade coming off at around 3,000 rpm would be a very interesting experience?!
