Oil Filter Part 2

A couple of days of off-and on work later, I had this. The filters (I can use either of the smaller diameter filters) have a 3/4-16 thread, so that's what the threaded nipple is. The nipple goes into the body, then the perforated cross-tube goes in. The cross tube locks the nipple in so it can't come out with the filter. The inlet and outlet galleries are drilled all the way through the body, and tapped for 1/8" pipe on both sides. This allows feed from either side. the unused ports will get threaded plugs. The final assembly is about an inch shorter than the Norton assembly, and smaller in diameter.

The location in front of the rear fender still looks to be too tight, so I'm planning to use the under-gearbox location. I like this because of ease of access.  

Here is a trial fit-up. I worry a little about vulnerability of the filter to road debris, so I'm going to do a little more work on tucking it up further. I might get another half an inch by bringing it in closer to the frame tube so the mount clears some features on the bottom of the gearbox.

I got to spend a little more time on the oil filter. I carved a chunk off one side of the filter mount to clear the gear box better. This would let me slide the filter assembly up further.

There is now probably more than a half inch additional clearance under the filter. The filter still hangs below the horizontal frame rails a little, but is well above the bottom of the center stand mounting ears.  

I think I've decided to put the filter assembly here. I'm still a little concerned about something hitting and distorting or piercing the filter, but for a strictly road bike, it seems unlikely. I may fashion a simple deflector that clamps to the bottom frame rails.

  Polished up the top of the mount for fun.  I'll probably paint it or anodize it black.  Also shortened the brass hose barb fittings to help with routing the hoses in the tight quarters.
