Ridge tiles are easier as most are at 90° hip are a bit more of a problem as they tend to be a greater angle.

Looking at colour photos the ridges seem to be a terracotta colour and rounded rather than angular. I'm guessing I need some half-round channel section from somewhere, probably 3 or 4mm diameter?

Anyone seen anything suitable??

Ridge, round or square it will be.about a foot or more across the bottom. I reckon you'll need something 7mm diameter. Least you don't need the flatter hip ones.

They could be either looking on my phone, but I have a gut feeling they are a bit of a mixture. Would not be first time people have used anything that's to hand.

I have been watching your progress with interest and venture to suggest plastic or even brass tube with a bit cut out. If you do it in short sections it could be held end for end in a vice and the section cut out with a saw.

Hi Ian

The thought of cutting a tube down did cross my mind but then I remembered I had some plastic half round stashed away somewhere.

It was duly found and seems to be about 6mm diameter. Originally bought when I first started in 7mm for guttering before I got my eye in!

It's quite a thick section and notably about 20deg plus more than half round. As a result it sits way too high on the ridge. So out came the big nasty file to make it half round...

The edges were then chamfered down with another nasty file and the strip cut into 18" sections. Out came the Mek and... It seems to be impervious to solvent. :rant:

So then a trial fix with some superglue, which seems to work.

And then some mortar (filler)...

Might just get away with it?

Could you put the file down the tube to chamfer the inner edges, in same way as the original section?
They seem to sit too high as is, and would look much better a bit lower.

Here are some hog back ridges (and my boots) - some are much less than 90 degrees:
