While you can't beat years of sitting in front of the screen like HD, here's a reasonable rule of thumb that I was taught for turning from base to intercept the LOC;
Start giving the ATC instruction to turn to the intercept heading about 1NM for every 100kts ground speed from the LOC. eg 250kts- 2.5NM, 200kts-2NM
By the time you finish the "turn right heading... cleared ILS...and the pilot reacts, the interception should just about a continuous turn.
As for adjusting the intercept heading in wind, as Throw a dyce mentioned, if you are trying to intercept at a track of 40 degrees from the LOC, you need to adjust the intercept heading to account for the drift angle expected on final. At normal jet speeds thats about 10 degrees for every 30 kts crosswind.
So if you have a 30 kt tailwind on base, you should increase the intercept turn by about 10 degrees; if you have a 30 kt headwind on base then you need to back off the turn about 10 degrees. e.g. in still air a turn from right base to intercept Runway 09 at 40 degrees would be to heading 050. With a right crosswind on final ie tailwind on base, the intercept heading would be 060. With a left crosswind it would be 040.
See how that goes.
