Okay, here is what I would do.
Go ahead and filter off the vegetable oil. Save all the bark/base mixture. Get hold of some isopropryl (rubbing) alcohol (higher percentage the better). Soak the bark in a minimal amount of the alcohol, filter the bark away from the alcohol, pull it once or twice moar with the alcohol filtering again each time. Combine all the alcohol pulls and evaporate them near an open window under a fan overnight.
In the morning you should have a nice resin of freebase alkaloid goop which you can proceed to process multiple ways from there. I would go ahead and finish it up using this tek . You'd be starting from step 4 "- Redissolved reddish/brownish wax in warm white vinegar, filter it.". Just follow the rest of that tek and you should be able to obtain a freebase of smokable quality in the end.
