Fciron thank you for your explenation and suport
when Frank Turley said before asking me how I control and maintain the length of the point my my full answer was ''some knoledge in geometry and experience''
the squar steel is having 21.5 % more matirial then the round in the same dimention . means that if you round a piece of squar steel it will be longer 21.5 % 1/5 but while rounding the steel after forging squar it swels a bit there for practicaly we calculat 13-15 % longer in this operation.
In every rond steel a cone is hiding and in the squar steel a piramid is hiding .The proportion in both of them between the full matirial and the cone and the piramid is 1 to 3 that means that if one leavs a ''blob'' of 1''
and start the forging from the behind towerds the point or with the hammer tilted or put the blob on the far end of the anvil you will always get a 3'' point !!!
The beuty is that geometry is working in All diameters the same 1-3 many people thinks that if the steel is thicker you need a smaller blob to start with and this is wrong.
and why did I start with the proportion between the round and sqar ?
if you forge the point on a round steel there is 20 % less matirial and you forge squar piont you will get the point shorter but when you will forge to octagon and round you will get it to the right designed length.
If one is forging a point from squar steel then one will have to start the blob a bit sorter 15% to get to the intendent length
After having this geometry knoledge one needs some experience to master it.
the longest point I forged in one heat was 10'' IN 5/16 AND 3/8 with my trick system

Hope I made it clear enough

Geometry is good! Thanks Hofi for that in depth answer.

Hofi,

Thanks for explaining. I misunderstood part of the technique; your explanation makes more sense. I will have to play with it some more.
