Thanks,

I no longer use tempilaq. I tried it at first but could not get good results... it is a PIA.
I simply watch the necks in low light, as soon as they start to change color (orange), the case moves away from the heat.

I think Lapua didn't get that memo....

I start machine with brass loaded and on first case as it is turning I aim torches at shoulder. The case rotates for 5 seconds and that is all the time I need to set up torches. Heat will migrate to the neck anyway, so it is not super critical as long as you don't aim it too far down the body of the case.
I set up my blue flame tip to just touch the cases as I find that easy to repeat and adjust timer from there.
If you haven't done this much, get yourself 5 old cases and set timer at max. Use the 5 cases to adjust torch angle and set those 5 cases aside for next time. After a while you will no longer need them.

I see you set up the torch distance from the case so that the inner blue flame tip touches the shoulder. Do you use the torches at full power, or a smaller flame? Reason I ask is that I tried this setup, with the inner blue flame tip touching the case shoulder at max power, and it took very few revolutions (under 3 seconds) until the case neck was red hot.
Erik, is that about 5 seconds with a single torch or a dual torch machine?Erik Cortina said:I guess I use them at "medium" power.
My cases take about 5 seconds. If your got red in 3 seconds, that's fine, simply adjust your timer to deal with that and you'll be fine.

Is this where you have the inner blue flame hit the case? The red straw indicates where on the case the inner flame hits.
