| azonenberg | Hmm, what are you trying to do? | 02:09 |
|---|---|---|
| azonenberg | baseplate for a vacuum system? | 02:09 |
| Sync_ | complete vacuum chamber | 02:14 |
| Sync_ | I need a second one for coating | 02:14 |
| Sync_ | and I don't say yes to the prices commercial ones cost | 02:14 |
| azonenberg | lol yeah | 02:33 |
| azonenberg | i believe it | 02:33 |
| Sync_ | the issue is that I'm not sure how expensive the flanges will be | 03:27 |
| Sync_ | gotta quote some of the stuff tomorrow | 03:27 |
| azonenberg | i am guessing expensive | 03:33 |
| azonenberg | but good luck | 03:33 |
| Sync_ | well, commercial flanges are spendy | 03:34 |
| Sync_ | but the flat stock will be the kicker | 03:34 |
| Sync_ | the problem is there that it needs to be 12mm thick | 03:37 |
| azonenberg | hmm | 04:27 |
| azonenberg | that is thick | 04:27 |
| Sync_ | yes | 04:34 |
| Sync_ | but required for iso k flanges | 04:34 |
| azonenberg | Yeah | 04:36 |
| azonenberg | Have fun makign those cheaply | 04:36 |
| azonenberg | Especially if they need to hold UHV without leaking | 04:36 |
| Sync_ | well | 04:39 |
| Sync_ | a readymade runs me about 50¬ | 04:41 |
| Sync_ | material for them is dominated by the cost of the bar stock | 04:41 |
| Sync_ | which is around 20¬ | 04:41 |
| Sync_ | pipe is cheap enough | 04:41 |
| Sync_ | and tig welding stainless to uhv standards is easier than one thinks | 04:41 |
| Sync_ | an orbital welding machine would be awesome but I have done it without one before | 04:45 |
| azonenberg | hmm ok | 04:56 |
| Sync_ | the trick is to have good fitup | 04:56 |
| Sync_ | and fusing two stainless parts together is quite easy | 04:57 |
| Sync_ | a leakcheck is in order after that, if there is one just grind the spot down and reweld | 04:57 |
