Additive Machining / Re: Moon Clock

Gerrit, the trimming is not bad but I do sometimes struggle with adhesion. I have never tried the glue stick thing. Which one seems to work best?

I usually use high hold hairspray.

There are a lot of large pieces in this clock so I wouldn't want to do multiples of too many of them because they lifted.

 :cheers:

Also be wary of being a seller on Fleabay: 99% of the time its ok but the "did not arrive" claim is sufficient for Ebay to give the buyer their money back if there is no tracking information. I always do cash on collection when I sell stuff on there  ;) .

Forgot to mention: Radio 4 "You and yours" have done a number of bits on scammers on social media sites.

That's a lot of fiddly trimming to do, will it not print without the rim?
I use a glue stick to encourage adhesion to bed. Once the bed cools down the print pops off the glass easily.

Many thanks for the replies. I think I will give Facebook a miss.
Now, where's my copy of The Exchange and Mart?

Hello Roger,

An ingenuous way to extend the shaft to compensate for the small size of your lathe. Excellent !!  :ThumbsUp: :ThumbsUp:

Will there be an outboard bearing to support that long shaft?

Thank you Kim  :)  That's just red marked pen to keep the orientation until I make some permanent marks.

Due to my small machines I could not make a long enough crankshaft so now I need to add an extension to drive the water pump etc. As the crankshaft was in the lathe I turned a small radius on the webs to make it easier to fit into the crankcase. The extension will be in two parts, a sleeve and a sacrificial extension shaft. I chewed up the end of the crankshaft on my diesel trying to start it and expect similar problems with this engine so I shall make it replaceable. The starting dog is not keyed to the shaft, just clamped, to act as a mechanical fuse.

The end of the crankshaft was turned down to 8mm and a 12mm sleeve was drilled and reamed to fit. The sleeve was then broached for a 2mm key. It will be Loctited to the end of the crankshaft and the extension will use the same key but be held in place with a couple of grubscrews.
