Thanks Bill,

I wouldn't worry about 3 unfinished projects - it just means you have a choice of what you fancy working on.   :cartwheel:

 :o I said the work word  :lolb: Don't you love its meaning once you are retired... Its over six months now  :mischief:

Do you still have some material to come off the bottom of the rod as your hole looks a bit high up compared to the drawing which should cure things.

I took 2mm off the end of the rod before assembling it. Its nearly got enough movement  :thinking:

The big end bearings were mounted on the same jig I used to turn the 5A bearings and turned to the same diameter as the end of the rod. Then a bit of fettling/scraping/fitting to get the round and round testing to feel just right  :)

Thankfully I decided to use 5BA studs and nuts on the slide guides as I think 4BA as shown on the later drawings would be too close

Hi Jo

Looking good ..  :ThumbsUp:

However, kindly dab in and get the support bit from the base to the lower cylinder cover sorted ...  :thinking:

Stop this thing going through my fevered little brain ...    :Jester:

Not a lot to show today  :disappointed:

I've pinned the crank, cleaned up/shaped the bearing caps and made some oil pots to enable round and round testing to progress.

Hopefully achieve a bit more tomorrow  :-[

I started the morning by taking the sides of the standard down so that they were level with the guide bars.

To enable advanced round and round testing I decided it was about time to machine the flywheel which of couse was already machined undersized  :( the worse bit being that they did not level up on the inside rim of the flywheel or centre it  :wallbang:  :wallbang:

It was easy enough with a quality three jaw chuck to get it running true again to be able to bore the centre and skim the edge faces. I chose to mount it on an arbour to skim the outside edge. As per the original drawings I chose to add a key in my flywheel so used a broach and before cutting used it to make sure the key followed the line of one of the spokes.

The Flywheel and the standard have been primed up so I couldn't re-assemble the engine so far so I have started on the steam chest by machining the two large faces flat. I can now start working out how much I want to take off of each of the sides, thankfully there is plenty of metal to come off  :)

The flywheel looks to be sorted :ThumbsUp:  :ThumbsUp: How big is it? I am guessing that it is in the Colchester.

I'm not entirely sure Roger  :noidea: , I suspect the inside curve is still going to go wobbly wobbly when it goes round   :-\

Its 180+mm diameter and yes that is Big C doing that bit of the turning  ;)

Best get that new compressor on order as it won't belong before you will be wanting it to go chuff, chuff at the rate you are going :) Lucky that the previous owner had not bored the flywheel as that would more than likely have been off.

PS Don't tell the little fellow but I just bought a set of castings :-X
