Guardian Prize - Having Trouble Placing In The Grid

[Orthrus]

So with today's Guardian Prize, I've got the theme and 10 of its associated partially unclued answers, and all but 16 of the others, but I don't understand the instruction about the solution to "normal" clues, and I have no idea how to begin placing the answers in the grid. Can anyone advise without outright giving me any of the answers? I'll take my humiliation.

[Lie-in King]

"The one-word solution to a normal clue is to be entered in the grid in two parts" - you need to divide the answer to -

"He'll take drivers round the course" into two 3-letter words.

Of the 2 10-letter answers, the first alphabetically goes in on the right.

[Orthrus]

Thankyou! Re: the 10-letter anwers, I thought that was the case, but I hadn't been able to exclude the other one from that position as I haven't solved the clue which begins "caravan" yet, and if that began with the same letter, it could also have gone there.

[Lie-in King]

You're welcome, I'm glad I didn't spoil it :-)

[Orthrus]

So I've hit a glitch:

I was proceeding quite happily with the order round the perimeter being DIE WALKURE, SIEGFRIED, GOTTERDAMMERUNG, DAS RHEINGOLD, as this fits the two three-letter words initially, and it gets quite a way with al the answers I'd already got...

*until* I get to the point where the last R in GOTTERDAMMERUNG (top right) has to be the beginning letter of either RING or RIEU, giving a five-letter word beginning with, respectively, G or U - and there aren't any of these, no matter how much I try and convince myself my other answers are wrong.

So, have I balls-ed this up somewhere?

[Lie-in King]

The last letter of the R-word begins a 6-letter word, not a 5

[Doubleread]

Das Rheingold is the first.

[Lie-in King]

Doubleread - Orthrus has the order correct.

[Orthrus]

Thanks again. I've tried, but had to give up with about half a dozen to go as I couldn't place one of them at all, and couldn't parse quite a few of the ones I had got. They've beaten me this time, hats off to them.

[Orthrus]

OK>

I've gone back and almost finished it this time. Just two I can't get:

Milton's brother with name which precedes Barnet (6) F?I?RN

and

Petrified wood with antelope circling gaming area (3,3) B?G/?AK

Any ideas?

[baby1234]

Are the instructions wrong? Should the start be top right square rather than bottom right hand square?

[Orthrus]

No, I've started in the bottom right and got them all in except for those last two that I can't solve.

[Toorak]

Friern
Bog oak

[Orthrus]

What's the construction of BOG OAK?

FRIERN I tried with an A where the E is, but couldn't find anything.

[Lie-in King]

Bog oak - 'bok' (antelope, round) 'Go (game) a(rea)'

Friern - 'frier' (Milton's "friar") + 'n(ame)'

[Orthrus]

Ah, OK. I'll take that one. Cheers.

baby1234 Starting at the last square in the 4th row gives the 4 components in the correct order. I know it's a cycle, but I wouldn't want to sit through it twice to get them in the order indicated by the preamble. But, TBH, I wouldn't want to sit through it once.

[baby1234]

Biggus56 it clearly says in the instructions start bottom right clockwise and it doesn’t work out. I put them in from there and the two 3 clues were wrong at the sides. If you do it from top right the two 3 clues are correct. At this point I decided this puzzle wasn’t for me. I couldn’t be bothered to print it again only to find out I was wrong again. Trying to be too clever in my opinion. I had solved most of the clues but couldn’t be bothered to try to fit them in. Waste of time. Now in the recycling

[JJ109]

Actually you are both right!
You can start top right with Das Rheingold or bottom right with Die Walkure, simply because Das Rheingold is the perfect length for the right hand edge finishing at the bottom!

[MOBIUS]

This has been a real challenge, especially as the instructions started Das Rheingold in the wrong place. I'm down to the last two: apparently the answer to "Milton's brother with name which precedes Barnet" is FRIERN, which must take the biscuit for obscurity this week. Where did Milton spell "friar" like that? Which leaves "Chap with mum's dog (8)" MA-E-U-E (assuming I've got my Wagnerian heroines the right way round). No word I know fits, so can anyone help?
