Default Weekly progress....

This week I have been focussing on positioning the dual circuit bake servo...

The Iruna brake servo has one M8 mounting bolt on one end and two m5 bolts the other. It is really designed to be mounted horizontally against a vertical bulkhead. The m8 welded on bolt is designed to take most of the weight and the two m5 fixing points on the other end are to support its weight and stop it rotating. The Royale Sabre does not have too many vertical faces strong enough to support the weight of the servo so I made up some 4mm think mounting brackets. It took a while as it was a kind of 3D puzzle to make them up. The Iruna has a bleed nipple on each slave cylinderso the m8 fixing hole is slotted so I can level the servo once the cars suspension has been set up.

Brake Servo support brackets bolted to offside chassis rail.The 'rusty' bar in front of the servo is the the 'A' post support. I've not finished de-rusting and painting it yet. Before final assembly the brackets will be primed and painted and the mounting nuts will be changed to nylocs. Pipe routing will be finalised and installed once I've got other components, like the fuel pump and filter, positioned and the engine is out again.

Another new component arrived this week.........

Fuel swirl pot or surge tank by marlinpeter, on Flickr

This is the fuel swirl pot or as it's sometimes called the surge tank. This is to ensure that the HP pump always has a constant uninterrupted supply of petrol. Looks like a nice piece of kit and was hand made by a guy in Wales who advertises on eBay.

Next up I will be mounting the swirl pot, HP fuel pump and filter.....
