your question doesn't make seance..
If the question is where do you "get" special teak logs?
The answer is by cutting many a lot of teak logs. You can expect to get 0-1 Special Teak Logs per inventory, although this is not guaranteed. It has been proven that it is possible to get more than one special logs in one inventory, or you could be unlucky and get none per inventory.
If the question is where do you "take" special teak logs?/ what do you do with them?
The answer is
The free conversion requires 2 of the same type of special log.
2 special teak logs can be used to convert up to 26 teak logs into teak planks.
2 special mahogany logs can be used to convert up to 26 teak logs and/or mahogany logs into teak/mahogany planks.
If you have 1 special or 1 of each, the sawmill owner will only offer to buy your special logs.
P.S.
It is confirmed that Managing Miscellania will not produce any special logs, as stated by Mod Emilee.
