Spoke with Delta Cams.
They think they have a grind for me.

Finally have the bulky items on their way from Lotus Supplies.
Two fuel tanks, trailing arm, pistons, and instrument binnacle so that I may engage in the wiring.
This takes care of the large items so the rest should be simple to have shipped.
A few more engine items to get but I think bearing, lower gaskets, timing chain, gears, etc. should be fairly simple to obtain.

77.8mm - 1595cc sleeves arrived this morning.
Paper shim set included.
I may use a fine ball-hone on them for a smoother finish.
My originals appear to have a plating on the exterior to slow corrosion?

  Nice to see the plan coming together. Does that size liner allow for the connecting rods to go through? my 77's didn't but the 79's did.

Had not thought about it.
I will check later.

Another critical part has arrived, a replacement Intermediate Shaft (Rear axle) as one old one was damaged.

Yes, 77.8 mm bore does let the stock rod pass through from the top.  :)

The only non-essential part I ordered arrived today from r. d. ent., a "Lotus" cast TS valve cover that was on sale.
Yes they are heavy, but my new 1595cc (Not 1995) engine should be making around 130 HP?
So I am allowed this one little bit of "Bling"!   ;)

1995cc?

With a 77.8 bore?

Maybe 1595cc?

Doh!
Yes, 1595cc.
Typing is still not really one of my best skills.

As long as I am on here.
Anyone tried having their lifter faces TiN plated?
Comp Cams offers it as an option for their cams but the cost is $250.00.
I am having my Europa cam rebuilt by Delta Cams out of WA.
I expect that eight small lifter faces would be much less expensive to have plated than a cam.

Also still trying to pull together the information required to go to Beehive springs.
They should be stable with less seat pressure which would also hopefully extend cam and lifter life.
I have this strange desire to only rebuild this engine once.

Found a little time today to contact a couple of companies about TiN plating my cam followers.

I will be sending a pic and possibly a sample to get quotes.
Only eight pieces so hopefully not too expensive.
Should be less than the $250 that Comp charges to do one of their cams.  :headbanger:

There may be a quantity break if anyone else might be interested.

Oooof!
I had expected that TiN coating my cam followers might be moderately expensive.
But $600.00 min charge is a killer.  :o
However, I am also told that there should be enough space in the minimum order for additional components.
I am also told that there are better coatings available, but no price yet on those.
This is one of those things best done in a larger volume.
I think I should be able to add my rockers with no issue.
Not sure what else might be worthwhile, maybe cam sprockets?
I have not heard back from the other company yet.

To do this I probably need to add more components from some of my other engine builds or get some fellow participants to go in with me.

And another wear reduction strategy, https://hekimianracing.com/2016/12/22/cryogenic-treatment-pricing/

This one includes a price list!

The baffling of my modified oil pan that I question the efficiency of.

Does that sump baffle work, Richard? . . presumably it does.
I'd be tempted to replace it with something along more traditional lines utilising a full top plate and an enclosed area for the pick-up and one way trap doors.

Here's some previous discussion on roller rockers, if that takes your fancy.
