Hi Fred,
Your post above (on 29th I think), you make a comment about how difficult it was to remove off the pattern, and I'm not surprised!
Did you ever consider making the rad-outlet dip in the bonnet as a seperate part of the bonnet mould? A flange round the edge and dropped in and then
obv through from above?
Obviously, you're not going to do it now, and I don't know whether it would be better or impossible from the Pics, but I just wondered
whether it had crossed your mind or not?
Rgards,
Steve
And keep up the fabulous progress!!!

Hi Steve
I think I can see on the mold some small areas in the depth of the nose duct where it "hung up" . Possibly this is because that is where
it was physically much more difficult to apply and rub out the wax, so maybe my preparation was not as through in that area.
I did consider (in fact agonized over) making the duct section a separate section, and I suspect I will still regret not doing so. This as the return
section under the nose goes back a long way, such that now I will probably have to work though a gap between the front side of the duct return and the
rear edge of the under nose piece when laying up some of the detail inside the front of the nose. I think I will have to make my under nose return
shorter than on other T70's to make this possible. This is the section of the pattern I am working on now - see the last pic above. Thanks to
another forum member I know that the GD goes back under the nose (from the bottom of the front opening in the centre) 385 mm. The rough surface you
see on the pattern now is a bit longer than that.
So far I have tried to do all my moulding work "in one", but I have seen it stated that large mouldings can be done in sections, and
because of the above problem might it be more practical to layup the part surface in the majority of each separate mould piece before assembling the
mould pieces together and completing the nose?
How does one do that? Is it a case of stopping the gel coat application say 30 mm short of the join lines, and then tapering out the part layout just
short of the edge of the gel. Then bolting the mould pieces together, applying gel over the joint sections, and then completing the layup? Would the
result be satisfactory, or must I make every effort to do the nose layup 'in one"? I'm starting to think that might be very
difficult.
As you can see I am still learning this stuff as I go along.
Cheers

Hi,
I cant comment from experience of having done it my self. However if you look on you tube there are a large number of videos by a guy called
"how to build a b1 bomber" and he sprays the gel cote in to the mold sections then lays up the mold sections timing the edges once they
have gone very tacky and then glues the sections together however this seams to lead to some very long days while he does all the layup.

Hi Fred, looks like you are making lots of progress! looking very nice indeed. ive just finished and mounted the main body shell on my car which
although ive done it in 2 halves it was still 2 fairly large but really complicated pieces to lay up so really needed to be laid up in sections.
i put the gelcoat on the whole thing and then put the first layer of glass over that on the whole thing. once you are at this stage you can sart to
lay up in sections as your resin will be air inhibited meaning that you can leave the section you dont want to do yet and it wont fully cure until you
do lay more glass over it. just needs a quick sand and then prime with some acetone as usual.
id only lay up thin sections at a time so that you are gradually building up the thickness over the whole part, if you go thick in one area before
moving to the next you may get un-predictable warpage.
Cheers,
Russ.

Slow progress.
Worked up the surface on the nose underface, made the formers for the flanges and now waxing.....

Not actually thanks Steve, circumstances have dictated that I have not had any Garage Time at all over the last 6 weeks.
I am hoping to get on with starting the layup of the last bit of the nose mould this weekend though.

Got the first 2 layers onto the last part of the nose mold. Now need to tidy up the edges around the nose openings.

This is absolutely amazing.
I teach CAD here in the UK and am now going to show this thread during my next lecture as I think its amazing, the range of skills you have used and
an attention to detail that I could only dream of.
Please keep us updated and again, absolutely amazing.

Hi Guys, Thanks for the encouragement.
So one night this week I invited some mates over to help lift the nose pattern, and we demoulded the nose again. Then moved the nose mould sections to
storage. I assembled the complete nose mould and finally I can see inside it.
The dark specs you see in the detail pics are bit of plastacine

This weekend I cut the front off the nose, to keep to one side to use later to sort the headlight recess/covers detail, and scrapped the rest of the
nose pattern.
I have retained the scuttle section of the pattern as I still have to do something about the returns and internal details in the scuttle.
Now I can get on with the tail mould. The door moulds are still on the pattern so I can mark the forward edges of the tail section.

No going back now, though the moulds are looking fantastic quality.

Awesome! Moulds look great.
I'm sure you weren't sentimental about it, but that's still a lot of work to be scrapping...

Was cutting up the buck hard given all the hard work put into making it?
Looks like a first rate job. Keep up the good work.

I'm not sure I'd of been able to scrap all that hard work as easily as that. Top draw workmanship, wish I had 2% of the skills
demonstrated
