Sally Shaper is not well!

(1/4) > >>

John Hill:
Poor Sally, apart from a few minor things like a missing pin in the cross feed mechanism Sally has a bigger problem, hardly suprising I suppose that time has not entirely passed her by. :(



Here is a picture from her family album which clearly shows the square headed bolt which is used to clamp the head which otherwise can rotate about a horizontal axis.  This pivot has got a bit slack, in fact one could say that Sally has gone a bit loose in the head.

This slackness no doubt contributes to the chattering problems I have when running her, so what to do?

Well, take it apart obviously, first step one would think.  But my Bodger Brain is thinking that maybe if I just force thick grease in the bolt hole something magical might cause the problem to go away or become less.  Maybe Modders know of something better than grease?

bogstandard:
Thick grease will not cure it. Otherwise the whole machine world would be running packed out with thick grease.

It has to come apart and get measured up to see the amount of damage. Only then can a repair scheme be thought about.

But prepare yourself for some four jaw and boring work.

John Hill:
What time of the day is it over there Mr Standard?  Surely you should be still tucked up in bed instead of reading wistful thinking from the antipodes? :wave:

I wont be getting the boring bar out just yet though,  apart from a couple of round nuts for my compound slide my turning careed has been pretty much limited to a yet unfinished gyroscope! :coffee:

bogstandard:
John,

I sleep when I need to, and don't when I don't need to. :med:
Usually a few small power naps in a 24 hour cycle. I have a very sedentary lifestyle, plus I don't need my beauty sleep any more.

I know it can be very difficult if you don't have the relevent tools and experience. But at times it has to be done, and that is when the gents on here can help you cure those headaches.

John

John Hill:
Well Mr Bogs my lifestyle is still fairly active which is something I blame on the current economic situation! ::)

Whatever, your mention of boring bars might be what done it or it might have been a miracle but when I pulled the head off and laid the bits out on the bench everything seemed OK, no sign of damage anywhere.

So I put it all back together with a bit of oil on the surfaces and now no amount of pulling or wriggling will get the play back.   :scratch:

So I set her going and she faced off a small block of mild steel and hummed while she was at it, even cutting a decent recess into the steel and no sign of the chattering tantrums of yesterday.

However, trying to cut a slot sets the chattering going again but as she cuts so nicely with a rounded end tool I will have to pay attention to the shape of the slotting tool,  some of the references say slotting is the hardest to do.  (Now why would that be?  Would it be because slotting is probably the most useful function of a little shaper? :coffee:)

Time for bed now, no time this evening for the gyroscope project!
