Modifications found so far:

Lengths of the tops of the columns parts 23 & 24 shortened.

Between holes length of Eccentric rods shortened (was 44.45mm now 42.07mm)

Piston rods and connecting rods remain the same length  :headscratch:


I have never seen so many 5BA/7BA fasteners on a model and all the fasteners are missing from all of the casting sets  :(

Have you tried Fuson360 , you can assemble parts ,animate them, and produce paper drawings

And the best it's free to hobbyist

If you are into stress analysis it will do that as well


Not bad for nowt

A handy feature is you can cooperate with others to evolve the design

Stuart, I already have Alibre PE and am happy with that, does all thos ethings except stress analysis. There was quite a bit about Fusion360 on ME forum a few months back but at the time you could not print 2D drawings from your 3D parts, good to see thats available now.

May look into it if I have to change computers as my Alibre is out of date now but then I would not be able to open the drawings I already have.

Good news about the fixings Jo as it will allow you to make them all from stainless rather than try and clean up a load of old rusty ones and I'm sure the nominal length Stuart studs would not measure up to your exacting standards.

:o Who have you been talking to I paid good money towards engine set three: it was a BOGOF  :naughty:


As for drawing package: I have cubify which is backwards compatiable with Jason's Alibre  ;).


Jo

P.S. I remain to be convinced if acquiring engine set three was a good or bad idea, I am expecting to regret it  :(.

I think Stuart wa srefering to Fusion costing Nout.

As I said to you last week, I hope the person with the castings paid you to take them away :ROFL:

PS will you be adding reversing gear to one or all of them?

Reversing gear is a standard fit on the triple  ;)

Jo,
The harder it is to correct engine #3 the more pride you can take in the result. I'm sure that all of us believe that you will succeed. There is a LOT here for me to learn and I am so looking forward to it.

Thanks Alan  :)

I am still trying to get my head around the long term future of these engines. Normally I like to keep all of them  :embarassed: But I rather can't see the point of keeping two Stuart triples  :shrug:

Maybe my Mother would like one but if I gave her one I know it would get polished to death  :paranoia:

Per a previous PM, perhaps you could mod one up and give it to your sister  :mischief: :naughty: :stir:.

I'm still looking for suitable "bung" material for those random :Doh: fastner holes in lucky 3's base. CI is only available in sizes over 25mm diameter and I am not looking forward to the mess from turning that stuff down to make 4mm to 6mm plugs  :ShakeHead:

I managed to acquire  :naughty: a dozen 1/4" soft Iron rivets but was not sure if they would be suitable.

Part a bit off a say 6mm slice and hacksaw it to a couple of square strips then turn those down just a thought

1+ for what Stuart suggests, much like cutting that insulating material into squares on the Kiwi. If you have some quare or rect CI block then just use your power saw to slice some off.

Alternative is to open out the holes quite large so the new hole will only fall into the filler material and then it does not matter what you use as the drill will not wander towards the softer infill.

Although your rivits are soft iron they are more like wrought/mallable than cast

Another useful source for thin Cast Iron is to chop up a casting, I'm sure you must have a spare one or two knocking about ;)

Something like this base from my Galloway that did not get used has provided a couple of valve chest covers and could easily be cut into squares for turning into plugs.
