Aye, i agree with that, i sometimes help my builder friends point patios they have laid etc, and their cutting in compared to mine is dodgy to say the least, especially the curved cuts.

I've never done a curved cut before. I was thinking when I do I'll lay the flags in position and peg them stable and then do it. If it goes wrong just whip them up and try again.

i genrally lay them all out overlapping the finished line and cut the lot in one go freehand, or another method i have used is to fix a length of draining rods and get people to hold them in the right curve whilst you mark the flags

That's a bloody good idea. I'd have never thought of draining rods.

^^ I find it easier to lay the flags over the cut 1 day and come back and mark the curve the next
I just use a tape and find the centre of circle
then mark with a paving marker

ye but alot of the curves i cut are just random curves going in all directions, with no where to measure from if you get me

Hi guys
Finished doing all my bit and bobs in the garden and laying the patio so decide to start mortaring today. Weather forecast from 4 different weather stations said no rain for the next few days.
Ummed and ahhed for about 2 hours cos it is overcast and decided to go for it. Anyhow after doing 1m2 with black die I noticed a few spots of rain. I aborted and took it all up and blew out all the joints. Another thing I noticed was there was a the odd dark blemish on the patio here and there. I got a tiny amount of boiling water with detergent and scrubed it up no problem. I am now testing some stones placed in my own garden.
The question I have is as my mix was certainly not too wet or dry is the humidity caused by being overcast causing the colour to ever so slightly go on the stones or have I possibly put in too much dye?
Cheers guys

Refer to this:

You should follow the guidleines given by the manuafcturer for the % of pigment. If you're using a powder it's generally a maximum of 10% by weight of cement but it's essential to check. Most say start off at between 2.5 and 5% by weight of cement and take it from there. If a liquid pigment, again follow the manufacturers recommendations.
Generally the more pigment you add the darker the colour but remember after a few days it will dry lighter. Measure all materials accurately and consistently to avoid a patchwork quilt.

One more!
Got 2 mortar joints I'm not happy with that I'll redo and one hollow sounding flag. How can I avoid this in future. they were thumped down as hard as I dare and the mix wasn't too dry and I used SBR so what gives?
Cheers

I wouldnt worry about the hollow sounding flag, unless its moving then leave it be.
To get sandstone to proper stick to the bedding a bond bridge needs to be used IMO.
