Evenly spread the oil through the center of the joint or better yet a blunt, but that's tobacco. It will burn slow if done properly if not it will run bad. The roach has the most concentration have a clip ready to smoke dat shit to the last piece.
Edit : for ecigs look up the vaped company and get the wickless cart as the wicks burn and taste funky while the ceramic element works as a great heat buffer. Use that cart on any 510 threaded battery and I suggest looking for a adjustable/variable temperature battery that easily allows you to adjust power output while external charging batteries you can get 2-3 at a time to be ready to use your vaporizer wherever.
The dab rigs are good ideas. Get a glass on glass piece with a female to make glass on glass piece to fit the downstem, a glass on glass water pipe of course, preferably titanium over quartz glass nail as the titanium holds heat better even though glass is less likely to affect the taste of the hash, and a glass dome to fit over the nail. There are pieces called oil reclaimers that are optional and fit between the nail and stem with a detachable piece where the oil collects so that you can take the piece off and collect up another dab.
Also for easy simple hash oil quality hash look up QWISO. It's a very easy low risk method to produce hash with isopropyl alcohol. Isopropyl is flammable, but reasonable amounts should not be a huge risk if proper risk management practices are in place. Can produce blond hash that when scraped even dry will darken in color. Definitely wait for the tray to be bone dry completely,which will happen faster and only with concentrations above 90% preferably 99% as the less water there is will lead to less chlorophyll and stuff getting in the mix as well.
