Evening, I want to make some pope ups the above size - never made anything that size before onyl 14/16mm and maybe smaller. Any tips, experience of doing so? I was going to use 20mm & 22mm cork balls and go from there.

What you looking to hold up ? 20mm cork ball would take a house brick to sink

Big old pop ups mate - do you think I should scale down then?

A decent 12mm cork ball with paste is fine for a size 4/6 hook.
14mm cork ball will hold a size 4 up for a long time. That would still be around 16mm with paste

I am using 22 and 24 mm baits and I want the pop up the same size.

70g basemix
45g Pop up mix
10ml preservative
5ml liquid food
5ml flavour
1x egg
Boil for 2 mins
Air dry 72hrs.

I wouldnt ever use pop mix - dont trust it. I want to be able to fish chods or hinges and not worry about them sinking.

With the right mix you can. Cork balls the size you're asking about will be a nightmare to weigh down.

You could always core a mix based pop up & add a Cork plug, best of both worlds.
I've never made pop ups that big but, thinking aloud, if you're happy with your 18mm mix/Cork ball ratio as it is, you can scale it up to any size theoretically.
Ie, for example if your 18mm is 4g mix to 1g Cork ball = 4:1 that's 5g total/parts.
5g divided by 18mm x 22mm = 6.11g (r) total, divide by 5 = 1.22g (r).
So for a 22mm pop up the Cork ball would weigh 1.22g and the paste 1.22 x 4 = 4.88g
Order some Cork balls, weigh them, sorted.
Fairly sure that's right technically and assumes Cork ball buoyancy to be standard and reliable.

Thats my worry - hence the question. It would take some serious convincing to get me to trust a straight mix. Glass sphere ( please save me the health drama ) I wonder about the mix and getting it right to pop it up and ( same with the cork) not need to much weight . I will order some cork balls do the maths as mentioned and go from there. Thank you for the replies thus far.

I don't think the calculation would be as simple as this. The cork ball dimension is the diameter of the sphere. For buoyancy we are interested in the volume. When you increase the diameter the increase in volume is exponential rather than linear.
Theory is great, but in this case I would just buy some 16, 18 and 20mm cork balls and have a play about with the thickness of the skin vs buoyancy, you can always have a thicker skin of paste around the ball if its too buoyant.

If the density of the cork ball are equal, it will be a linear calculation
Density = mass/volume
So, if mass increases with a factor 2, volume should also double or the density isn't a constant value

If we are comparing natural cork balls then the density will almost certainly vary. I did misread the original post though, apologies Vossy.

Can I ask why a pop up so big ?

After makng a few dodgy assumptions, I predict a 18mm cork ball in a 24mm boilie would make a decent wafter. A 20mm cork ball should make it pop up, but only just. A 22mm cork ball would require a few grammes of putty to hold it down.
