I wonder if anyone can help with some pictures as to the best way, and in fact how, to set up an external oil filter on a 1927 coil engine. I need to know where is best to set up the pipework running into the filter and if there are any modifications needed to the engine to achieve it. Rubber, copper piping or braided? Any modification to the oil pump?
Any help would be most grateful.
Thanks in advance.

Hi Tim,
There was a thread on the old steam driven forum about this and many sent in photos of their installations.
Personally I've used one of John Barlows dinky little units (takes a small Renault Clio cartridge) mounted on the inner wing semi hidden by the dynamo. Derek's installation looks good with the neat pressure gauge line.
The thread up the rear oil gallery is 1/4"BSP, you have to tap past the oil pressure gauge drilling and fit a blank bung bottomed into the end of the thread. The gauge drilling should also be taken out to 1/4"BSP and a straight 1/4" hydraulic fitting put in making sure there's no restriction in it, drill through if necessary. Similarly a 1/4"BSP fitting in the front gallery connection mates to the fitting on the delivery pipe - for the few psi rubber hose is fine and being black tends to be less obtrusive. 100R6 hose and fittings are available from that well known Internet auction site.
Although this installation doesn't filter the oil going to the rear cam bearing or a centre main bearing, the general clean up from the many rotations the oil performs will result in a very clean system.
