Don't worry, now he has been let loose on the real thing these smaller projects are hardly a challenge anymore. 

If you see the old chap slacking Nigel, let us know and we will set up another DIY SOS project so he can keep his skills honed... 

[FairTmiddlin]

It may be a DIY SOS for the model if this doesn't go right

I had a girl friend like that once. She was a model too!

I was going to say she chucked me because I was straight!

[FairTmiddlin]

Grendel maybe printing the screen out in 3D first may help

[grendel]

now that is the first sensible suggestion I have seen, and I hadnt even thought of it myself.

Though many the time i have got half way through something and suddenly thought, that it would be so much easier to 3d print this than sit here filing a big lump of brass or steel.

Many thanks Nigel for inserting that thought.

[FairTmiddlin]

At least you can work the finer points of angles an hinging lines that way

I have the basic shapes in my CAD model already, so it will just be extracting those, and thickening them up to parts, then cutting along the join lines.

[FairTmiddlin]

It's being an engineer, that helps in problem solving you see.

How many wooden sets did you make last time?

This time print them out of brown plastic an use them

Looking better all the time

Yikes! He'll be encouraging us to print plastic planking next, then it'll be cabin sides 

[FairTmiddlin]

If they could make boats out of concrete what's wrong with printed plastic. Print the hull in one go it won't leak like sieve

even drawing it up in CAD for 3d printing is a challenge, , an hour and I have the front screen prepared, it just needs the intersection angle between it and the side screen doing, but I have to do the side screens and the plinth first the plinth has to be flat and horizontal on the top, rounded on the bottom, and angled back to the sides

[grendel]

here we are so far the angles at the sides will need to be cut yet

Well it looks too big to me, but here we go

  off to check the cad model, I think I have dropped a clanger here, the model is generally modelled at 1:1 in CAD, so I have imported the part into the printer- it has chosen the units for me, and likely scaled the part to 1:10 not the 1:12 I need so I need to scale it to 83% of the size it comes into the printer. 

[grendel]

So the base has printed it all fits together but its too big

[grendel]

reprint time, this time at 83% at least I can fit everything onto the printer bed in one go this time, but it all fits together, so I know I will have a fair pattern to make the wood version.

just got to wait 3 hrs 45 minutes for it to print now.

[grendel]

I have this horrible feeling its going to be too small now.

[grendel]

the one I have printed is too big -

[grendel]

Ah I think I may have found the issue, one part may not have scaled properly, I may have hit the button twice or something. fingers crossed I just need to reprint that one part.

[grendel]

so while waiting for prints I made a decision and visited the southern model show today rather than tomorrow, this is a good place for bargains on parts, so Radio gear has been procured as well as a sound unit, batteries and other parts I had been planning on buying for the models, some tools and other items were also procured

[grendel]

some pics of my purchases

[stumpy]

Grendel - "sound unit" conjures up all sorts of possibilities e.g. " 'Ow much? It don't grow on trees tha knows" for one!
