Nice work.
Also I am very jealous of the machinery in your workshop. I need a lathe. Keep up the good work

Thanks Will and Charles, I'm really eager to get this engine built and back in the car so I can drive it again.

I pressed on (literally) with getting the guides in today, and started on the seat cutting.

I need spin up the valve grinder tomorrow to clean up the valve faces, and flex hone the guides to fit the valves. Then I think I will check the stem heights to see how consistent the seat depths are.

Hi Simon, it'd be good to meet you, especially as you're relatively near. Guy's coffee is actually pretty palatable!

thank you, Phil

Thanks for the kind words Guy and Phil. It's been quite I while since I last visited GCRE. I think it was to have Guy run some flow tests on a Merc 320 cylinder head for my Crossfire, but I do remember the fresh coffee! I definitely need to make the effort to pay another visit, especially as I'm not that far away and have an ever increasing list of parts I need for the build.

Speaking of which, I've got a bit sidetracked with fixing up the old Wolf valve grinder I've had sat on the bench for years. I'll post up some progress pics later this evening.

Simon.

ah, the Crossfire, yes I remember vaguely Simon!

Too many years ago!

Thanks Guy, I will definitely be up to see you at some point with a shopping list!

Having now got the head pretty much done, I spent some time refacing the valves (after having to rebuild my grinder) but was a bit concerned about the amount of material I had to take off the exhaust valve faces so will be opting for new ones. I have also spent some time prepping the crank and working out locations for the crank sensor as I'll need to commit to welding the toothed wheel in position before balancing. I'll post up pictures of that later.

In the meantime I have started work on a big wing sump as I want to get all the dirty fabrication out the way before cleaning everything up for the build phase. It's a composite of the various designs in Guy's books and the threads on this forum.

Next job will be to tack the oil pickup in place, reposition the oil return and start looking at extending the interval baffle to enclose the pickup.

I made a bit more progress today by adding tacking the oil pickup in place and starting on the internal baffling.

Small section added to extend the top baffle, picking up on the trapdoor hinge mount. This will need a bit of fettling when I reshape the oil return tube.

Still need to drill some vent holes for the side boxes and make up the tops of the boxes, by have now run out of steel!

Thank you Guy, Will and Piotrek, I find this sort of thing a nice break from the day job.

I spent today trying to finish off the fabrication of all the sump parts ready for taking together.

I repeat myself, really great work. You have done a really nice job on this sump. It will look great and work great on your track car for sure. Nice one
