My clutches have arrived from Polly Wobbles The bad news is that they are not the imperial ones I thought I had ordered but metric. Thankfully I had not machined where they are to go yet .Jo

Thankfully I had not machined where they are to go yet .JoWell you did say in an earlier post that they were 3.0mm bore But whey do you want imperial as the drawings are all in metric, are you now converting metric back into imperial
Ok Jo I’ll biteWhat’s with the colour code on the drawings never seen a reeves drawing with colours, Or is it some secret system that you use,
Just as well you still have plenty of time to raid the stationary cupboard at work for a few more pens
Thought you watched F1 it that technology or sport not sure
I thought the idea of a datum was all measurements were taken from it, that looks even more confusing . maybe it would make more sense after a glass or two?As for punching the holes I hardly ever do that now, just locate an edge and side (hence the datum) and use the DRO to do the rest.
What no rods poles or perches or chains ( opps that’s the distance between two sets of three wooden sticks in a field on which a rain dance is performed ) it’s 22 yards and they are chains with long links and are used in road layout Very old UK units of measurement Sorry Jo about F1
Strangely some of the colonies have totally accepted metric and measure speed and distance in Km but here in the UK good old miles still prevail. Same with plumbing fittings which are still all BSP

Yes the cost of replacing all the road signs like so many things in life was too much for the UK Government But they still chose to put £0.5795 tax on per litre of fuel + Vat @20% rather than quoting it as £2.63 + Vat per gallon which sounds more expensive. How many of us measure km per litre rather than miles per gallon for our cars? The measurement of science is metric and if you recall I am a scientist Jo
No ...you're a RETIRED scientist...….
Does that include NASA scientists
BTW If you look at many semiconductor package dimensions they are quoted in Metric but are actually in Inches. ie 1.27mm pin spacing is .050"
Still following your build Jo
1983, that would have been a year or two before I started my Minnie, built without a milling machine as was the beam engine that would have been made about then. As there were not so many hobbiests who mills them then and no DROs on hobby machines.Maybe if you get a minute or two to spare between all that hard work it may be worth drawing it out in Alibre to check and find any differences
I do not have taps or dies for M1.6 either so buying some is a very expensive option.
How are you finding retirement now that you have had a few months practise?
Still trying to get used to it. I'm told it has something to do with 'purpose'.Every day I wake up thinking there's something I HAVE to do but there isn't.
On this retirement thing: funny but sad, there’s been several people I’ve known that retired and shortly thereafter, assumed room temperature. Maybe that’s why I keep working
I thought that being happy and contented was the purpose of life
When I talked to the doc (a female) about it, she said it was typical for males to feel a sense of loss of purpose.She may have said that to make me feel there was nothing unusual.
Now, do I hate getting up each morning at 2:30 am, you damn right I do, and that’s where I start thinking retirement, but I just ain’t ready to start “watching me pennies”
