I have no idea what that second machine is.

Keen to see the scavenge pump done!

Oh, are you still with the fsae team?

:D Cheers plohl, yep I'm still with the FSAE team though I really don't get out there often enough because I work on my car so much.

It's a metal shaper, not really used in machine shops anymore but very useful for a home workshop (and they're cheap :)). One of the only machines which can cut internal keyways and they're very good at cutting splines, dovetails, gears and flattening large surfaces, all with cheap hand ground HSS cutters.

Spent many hours on a shaper in the first year of my apprenticeship. Cool machine to work with!
We have a greatb laser cutter here at the school now which is great to use.

Thanks MrPham, Gladiator and Veloce :D

The shaper is great, I haven't used it much before but it's great fun to watch working, mesmerising.
Having access to a laser cutter would be fantastic. I can use a few machines at TAFE but they're mostly for sheet metal working.

When I was at school 40 years ago, it was the machine voted most to draw one into touching it during operation. Not that I would recommend it though.

No updates just yet, apart from some bastards breaking both mirrors off my car when it was parked in the street :evil:

I'm nearly finished setting up the workshop at our new place, so I should be back to working on the car in a few days :D

OK I'm finally mostly settled down at the new place. The workshop is semi-organised (enough to keep working on the car, anyway :D) and I've made a bit more progress.

Firstly my new tyres arrived. They're Federal 595 Super Steels in 205-60-R13.

Image

Image

I've also stripped the auxilliaries off the engine in preparation for removing it once more to fit the dry sump system. I bought an engine stand at the recent hare and forbes sale to make it easier to build the new sump and supercharger manifold.

Image

I've made a bit of progress on the dry sump pump.

The jig for machining the bores for the gears:

Image

This ensures they're all the same. I've only machined one of the bores but to do so I had to make a new boring bar.

Image

It's pretty rough but it did the job. The pocket for the gear is bored to 38.12mm for a 38.10mm diameter gear and 30.50mm depth for the 30.48mm width of the gear. This should leave enough running clearance so nothing hits. The aluminium will expand more than the steel gears so the clearances should increase and it shouldn't seize (well, that's the theory. I might have not given it enough clearance, we'll see once I've got it assembled)

Image

Image

Image

I'm on uni break at the moment and I've put pretty much everything aside until the MX-5 is done, hopefully I'll make good progress.

Things I can think of which are left to do on the car:
Dry sump (inc. pump, pulleys, sump, lines, tank, cooler)
Supercharger (inc. manifold, fuel rails, fuel lines, pulley)
New exhaust (I can't find room for the drivers side exhaust with the dry sump stuff, I'm thinking sidepipes which join back together to exit at the rear to be legal)
Replace rear main seal
Install Walbro 155 lph HP pump
Install 1.8L rear end
Modify bonnet for supercharger clearance
Reroute coolant hardlines (again)

Simple, really :roll:...

Found time to bore another of the gear housings. The gears mesh pretty well, I'm happy with how it's going.

Image

Image

I've got the process down now so it shouldn't take long to finish off the other housings.

I'd say the pump is around 70% done now, not including the mounts or pulley. I've bored out all the gear pockets and most of the bearing ones.

Image

Image

Image

Image

The bottom right piece shown in the last pic slipped in the jig after the last cut. The hole is the right diameter and depth but now has a huge burr at the bottom. I might be able to fix it, I'll try tomorrow.

To finish the pump I have to drill and tap the inlets and outlets, bore out the end piece for it's second bearing and oil seal, put a keyway in two of the gears and make the drive shafts, pulley and mounting bracket.

Did I miss something - did you get it engineered/registered?
Didn't know a supercharger was going on.
