AndyB:
David, Myers are slow to reply but helpful once you make contact.

Sorry about the lack of progress last weekend; got a new 125mm 3 jaw and spent the time machining the cast iron blank backplate.

It should overcome some of my holding problems! :bang:

AndyB:
Hi all,

Still sorry for lack of progress...

Been putting up a 12' x 12' shed for her indoors.
I don't know...10 years ago I built a 16' x 18' garage to my own design. It seemed to go up in no time at all.

It took me 2 weeks just to dig out the base and concrete this one (had to clear loads of tree roots), then a week to strip and move it from its former location and another week to put it up in the garden (ok, it wasn't the whole of the week, just the spare time I have at weekends and evenings). A month to build a shed!!!!

I hate this getting old lark!!!! :lol:

I built it for her so I could clear the garage of the crap that had been dumped in there... saying nothing :bang:
Still, I have got my garage back, just got to sort it, then I can get back in the machine shop. :nrocks:

NickG:
I had to do the same Andy, although mine is only an 8x6 - it's full though, can't imagine all that rubbish being in the garage now! If she ever starts dumping stuff in there I'll just stick another shed up, she'll soon realise it's eating up her garden :lol:

AndyB:
Hi all,

The creature from the black latrine has re-entered the land of the living!

I tidied up my Photobucket album into sub albums and now they have gone from the log! Oh bugger! :doh:

I will have to reinsert them :doh:

Her indoors is happy with her shed but isn't doing anything with it yet...now why am I not surprised?

I have to be honest and admit to being frightened of continuing from where I had got to. There was so much that could go wrong so I had to build my confidence and exercise a whole load of prevarication! :lol:

One of my fears was tapping the 5BA holes so I hunted around and found a Champion Sensitive Drill...

This became the basis for a tapping tool just by making an interchangeable head...

I then drilled and tapped the base for the cylinder and inserted cut-down screws...making proper studs was a bit too fiddly!:

I cheated. The plan calls for 8 studs for the cylinder and 6 for the hot cap with 2 in close proximity on virtually the same diameter ring.
I set it all up in the Rotary Table and drilled right through both sets of 8 holes all of 22.5 degrees apart so no coming up against a stud coming the other way. The bottom ones can't be seen and there is a gasket between each anyway.

I made the cylinder liner which fits a treat! I am surprised! :bugeye:

From there I went to the flywheel bracket.
I took the advice given earlier about mounting on the face plate; found a centre and lined it up with a tailstock centre which took all of 5 minutes! I was very pleased. Set 2 changewheels as counterbalances and to brace the bracket.

Not a lot of room again here...

Faced the boss and centre drilled, and drilled out to 0.100" undersize ready for boring:

At this point I was told that my supper was nearly in the cat so had to retire for the night. The bore has to be spot on to take 2 press-fit needle roller bearings so I want more time and no pressure before I start.

AndyB:

:update:
Another day...and I have done exactly what Bernie has done! Grrr.... :(

Evidently the internal jaws on my lovely superdooper calipers overlap by 0.001 so my increments are 0.002 out (for the reason given in Bernie's project log)! :doh:

Oh well, find some 0.001 feeler guages and shim it up!

Having a cup of tea while I calm down. :(
