Oil Pressure, ...Finally

Finally got an oil pressure reading, but it did cost me an oil filter...

Tonight's mission was to check the oil pressure:

Battery connected - check
Starter motor wiring okay - check.
Drive belt clear of obstructions - check.
Oil filled(!) - check
Spark plugs removed - check
Oil pressure gauge temporarily tee-ed in to oil pressure switch - check

Time to turn the key.  Click, whirrr.  All good.  More whirrring, no oil pressure.  Scratching of head.  Key turned again.  Click, whirrr.  Still no oil pressure.   Hmmmm.

Had a quick search on Locostbuilders.  Seems to be a not uncommon problem.  One solution is to prime the pump and the oil filter.  Tried this by pumping some oil down the oil filter threaded spindle.  Also half filled the oil filter.  Tried cranking again.  Still no joy.

Frustration building.  Then thought, let's just prime the pump via the oil filter inlet and crank over, with no oil filter fitted.  At this point past caring if the garage walls get sprayed with oil.

Tried cranking again.  Success!  Maybe it worked better when there was no back pressure on the pump?  Anyway, refitted the oil filter and cranked for longer.  Oil pressure built up steadily to around 40 to 50 PSI.  Job done.

Next job is to find a replacement oil filter.  In my haste I trashed the casing of the old one with my cheap chain  type oil filter wrench.

Clutch Cable

With the Tiger floor mounted pedals the brake pipes are routed along the lower chassis rail.  Unfortunately this is where the clutch cable would normally be tethered.  There is pretty much only one routing where the clutch cable does not foul the brake pipes - that is in a vertical curve.

I fabricated two brackets and used rubber lined p-clips to hold the clutch cable in this configuration.  The clutch action seems nice and smooth and the cable stays clear of the brake pipes, oil filter and lower steering column.

This large bracket came in a multi-pack from Screwfix.  It is normally used to hold kitchen cupboards together.  After adding a 90 degree bend in the vice it is just right for the job.
