That's the easy stuff! I could have mentioned that when EASA first got involved we operated under the LAMPS system. Then that changed to the GMS/GMP schedule, and it's now apparently going to change to MIP. And no, I don't know what they stand for either, not without looking them up.
Another snippet is that if a regulation refers to aeroplanes you can safely ignore it, as a sailplane isn't an aeroplane. But if it refers to aircraft then you'd better pay attention, as a sailplane is an aircraft. Or was it the other way round?
I did something bl**dy stupid today. These crossheads took quite a lot of effort and then I went and put a crack in the boss of one. I won't say how, you can probably guess.
A club member has suggested a turn down the thicker part of the boss and put a sleeve over it so that's the next job.

I think I made eleven crossheads for Norden before getting one right…
Things are moving fast since diagnosed with Lymphoma last Friday had a phone call from Leeds Hospital they are admitting me for a PET Scan this Friday.
A problematic time knowing there is something very wrong internally just hope they don’t have to do major surgery and chemo might sort it.
Many people have been through this before and many have had a decent life after treatment.
It’s a sod was all prepared to build that full size steam bike but it is on hold at the moment even had offers from a Lad from my past to pay for some of the materials but like to be independent was a kind thought all the same.
At least can listen to Gabriel Uttley talk on fast bikes on Wednesday at my model engineering club before everything kicks off.
Been moving the people that have offered help when my treatment starts and is much appreciated.
I might have been interested in that Vauxhall but the rear number plate put me right off. The 2 St Georges flags mean that the number plate does not comply with regulations, apart from looking odd.

I admire your persistence! I'm not willing to make even one more unless this one breaks completely. I turned down the first 5mm of the boss and loctited a steel sleeve over it.
After an abortive attempt to cure the vibration in the clutch release mechanism of the Mk1 Super 7 I've now found the cause is a bent/worn actuating shaft. Fortunately the hole which it operates in is OK so I'll make a start on making a replacement from Ground Silver Steel when I can next get in the workshop .
Don't bother with Siver Steel, it's horrible stuff to machine. I'd use EN3 bright bar, or if you want something stronger EN8. If you want ground you can get PGMS from several suppliers, but the tolerance of bright is good enough for mere mortals like me.
I agree, but it's much a case of using what's to hand. Fortunately it's a pretty simple shape that can mostly be formed by filing. The only machining, as such, is the reduced end to accept the thread that retains the bearing.
Nice work as ever. I think you said you would be boring it and chain drilling the slots? Is that what happened? This would be an ideal job for the Tormach, using 2D adaptive clearing courtesy of Fusion 360 CAM – all done in one operation.
Last night I started a special dovetail bar for holding two telescopes side by side. I have a commercial one adapted already, but it's a bit short. I missed the Arc power feed (it went back for a check up after the trial but it should be back soon) for taking long cuts!
I've had a nice idea, which is a tab on the end with a camera screw fitted so instead of a second scope it will be easy to pop on a camera, or even better a small pan/tilt head.
One thing that worked rally well was using a digital angle gauge to set the vice at 15.0 degrees, the bar is a really snug fit in the mount.

Of course the easy peasy way would have been to use the CNC mill, although the 8" diameter is getting close to the 9.5" Y travel on the Tormach. But I have a daft idea of writing this up, so I thought I'd better stick to old school.
The 3/4" and 1" slots were drilled, "drilled" bigger with a slot drill, and then machined to final width with 3/4" and 1" slot drills.
For the 1-1/2" and 2" slots I chained drilled the circular end, and cleaned them up with a boring head:
The chain drilling is easy using the bolt pattern function on the DRO. The waste simply needs a light tap with a hammer and brass drift to remove it.
I was planning to chain drill the remaining waste in the parellel portion of the slots. But it was quicker to just hog it out with an endmill. Full width cuts (20mm) and 2.5mm deep per pass with nice blue chips soon removed the waste. Really old school, as I used all manual feeds and the endmill was HSS.
Andrew will you be bringing the plate along for inspection at the weekend? I'll let you of bringing the press too.
I suppose if the plate were mounted with the slots at 45degrees to the CNC mill axis you would have plenty of Y to play with even if using a large dia cutter.
The keyboard survived a dose of lukewarm tea, but following it up with a dose of bananas and custard was too much… one visit to PC World later…

I've saved a number of keyboards by stripping down, washing, drying, re-assembling. Rather fiddly, but not difficult – it's the drying that is the slowest part.
