Here is my current temp data on the v2.1 Forge. I would like to preface this data by saying that I have been hesitant to post it as I’ve not been able to gather a large number of data points and average them. These are just over a couple sessions, but the general trend seems to stick. As soon as I publish temps, I’ve been afraid that they would be disputed or different for other areas, etc. But realizing that not many of you will have access to a Scace device, I feel as long as it’s taken as a guide, it should be useful.
The next thing to point out is that the pre-heat temp was gathered using the temp strip that is available on this site and is commonly used by many other lever users. You may notice there’s a reading for 95C (203F) pre-heat, this is an estimation where 90C reading has gone blue in the way 85C does when you’re at 90C etc. Again, please use the below data as a rough guide for shot temps, you can notice that the temp strip may not be perfect (could be a “high” or “low” 85C reading), but I feel it works well enough.
A more accurate reading would be with a thermocouple tightened onto the plate, it’s a bit tricky to do this, and having my meter in the right spot for pre-heat as well as Scace readings is a challenge, but I have been planning to set that up for a while. It will be coming!
Shot temperatures with pre-heating:
| Approx Pre-Heat Temp (F) | Idle Scace Temp (F) | Lock in Temp (F) | Max Shot Temp (F) |
|---|---|---|---|
| 158 | 98 | 141 | 184.1 |
| 167 | 102 | 141 | 186.1 |
| 176 | 98 | 148 | 189.1 |
| 185 | 103 | 142 | 191.7 |
| 194 | 102 | 148 | 201.6 |
| 203 | 100 | 151 | 203.2 |
| Approx Pre-Heat Temp (C) | Idle Scace Temp (C) | Lock in Temp (C) | Max Shot Temp (C) |
|---|---|---|---|
| 70 | 36.6 | 60.5 | 84.5 |
| 75 | 38.8 | 60.5 | 85.8 |
| 80 | 36.6 | 64.4 | 87.2 |
| 85 | 39.4 | 61.1 | 88.7 |
| 90 | 38.8 | 64.4 | 94.2 |
| 95 | 37.7 | 66.1 | 95.1 |
The procedure for gathering the data was to first heat up the Forge as I normally do to around 70C and let it sit on the kettle, I usually do this while prepping a shot, so I took this time to setup the Scace. Afterwards I recorded the idle temp of the Scace sitting in the ring while on the stand. Then I pre-heated the Forge to the temp using only the strip as a guide, then locked the Forge in noting the lock-in temp before pouring in 100C boiling water. Fill Forge to the top and press as a normal shot up to 6-8 bar. The max temp was recorded during the shot press (usually temp peaks in the first 5-10s then falls slowly).
Any suggestions to the routine are more than welcome, as is more Scace data.
