Fake dry sump tank/breather. It will function as a breather box and be positioned in the correct spot for a Spyder dry sump tank; it is scaled-down somewhat to make room for the Accusump, with which it will be cheek-by jowl.

Thus, my car will have its behind-the-passenger area of the firewall occupied by the correct(ish) looking and functioning "oil tank and breather components," as original.

Couple weeks ago, me boi Jimmy-da-welder took back my gas tank and the 3/16 plate I made to strengthen and shim-up the filler assembly. He was excited to use stainless this time because it leaves fewer voids, so he promised a nice smooth, no-leak finish.

Couple days ago I got it back from him and sho-nuff: smooth, shiny; great.

Now to drill out the five holes for the filler....

what the..

HEY!!

Three hours (and several bits) into it, I now have half a hole. Tried the small bits, the step bit, went to the store and bought some Milwaukee colbalt bits. Broke two of them.

Tried cutting fluid, tried without fluid; slow, very slow and not-so-slow. I tried pulsing the drill, pushing hard, not so hard and too hard. Pilot holes, straight in with the 5/32, everything in between. 

I tried getting the tank up in my drill press. No-go. 

I tried the internet. The consensus there, among welders and drillers, is, when welding with stainless stick: DRILL THE HOLES FIRST, THEN WELD.

Now they tell me?

Jimmy says he can drill it for me but I'm not so sure. I guess I'mma just give it back to him and cross my fingers.

You're gonna need a very thin oil to cut stainless steel weld.  That stuff is beyond "wicked hahd".  

Cobalt steel drill (nothing else seems to do it) and drill slowly with lots of pressure to get the drill to "bite".  High speed on the drill just creates excess heat which anneals the drill tip and almost instantly dulls it while polishing the metal you're drilling so the drill can't "bite".  Be very careful - it's easy to break off the drill using this technique.

Cooling and lubrication are key, too, but use a thin cutting lube, like less than 5 wt.  I've had OK luck with 3-in-1 oil, but the best stuff I've found is sewing machine oil - about 1wt and clear - it drips like water.  Walmart fabric department - Singer/Brother/Husqvarna all work well.

I had to drill through 1/4" stainless plate for my driving light mounts and went through two sets of Home Depot regular drills before I heard about the Cobalt Steel drills and oil from a guy who makes safety railings for sail boats.  Old Navy CB who knew his stuff, but what he also said was "Always drill first and THEN weld Stainless."  

@edsnova- have you tried carbide drill bits? They're expensive, but what I had to buy when drilling holes in hardened transaxle parts. Cobalt wouldn't as much as mark the side of a gear. One thing to note- they are brittle. When drilling through surface hardened gears (the hardening was a 30- .040" layer) I broke 3 bits when transitioning from the relatively soft middle to the other side. Up here a good carbide 1/8" bit is just over $20 (broke 2) and a 1/4" bit is well over $50 (only broke 1 but you can still guess how loud I yelled "F*&%K!!!!") but they're the only way to make holes in hardened steel.

The sides were cut with ceramic inserts; again, the only thing that would last.

It is interesting how many old manufacturing sites all over the place have been converted to computer Data Centers in the modern era.

Why?

Because lots of places making, say, gears or castings or hot forgings had to either heat the metal up before forming it or harden the steel after forming (like Al's gears) and they did that in electric ovens.  Those ovens got WICKED HOT and they got that way via electricity.

So.... Having that much electric capability in the site in the first place makes it easy to build up an electricity-eating Data Center.  One of my old 492-drive storage cabinets ran on 208 volts, 3-phase at a steady-state of about 43 amps and we used a 60-amp wall plug - BIG sucker, half the size of a football.  Gimmee POWAH!

If anyone here has or knows someone who has a TR Spyder, I want (maybe need?) the supplemental wiring diagrams and instructions. My assembly manual refers to these but did not include them. Instead, I have

IMG_1149IMG_1150

I believe this to be the wiring diagram for an original 550. As you can see, it is in the original German. If anyone (Anand? Looking at you) wants a copy I'll gladly scan it and send. It's not really that useful for what I'm trying to do.

Thanks all.

I've been away from the car for about a week (Bridget is now oil-changed, bearing-packed, washed and almost fit for Carlisle duty), and during some of the frustration gaps while slowly tracing Spyder wires I have completed the firewall bracket for the Black Box.

No pic but momentous news: one of the Spyder club members gave me the key to the Thunder Ranch wiring harness. All color codes, saying what plugs into what. And it works! It's almost all correct, far as I could tell today in an hour or so reading the grid and checking/marking what I have. 

So I should be able to get the car actually wired sooner than later.

Thanks for the offers, guys.

Can't tow the car before it's titled and registered, and I don't think I'll get there in two weeks.

Also, still haven't made the tow bar system. 

Also, I can't tow a trailer with Bridget. No ball hitch.

Wiring I'm pretty sure I've got a handle on, Danny.

The motor though—that might be a thing. My plan is to get the car wired and painted, bit by bit, hang the clam from the ceiling and put the back half of the Spyder on the body dolly that Alan forced on me last year, then get the engine hoist out, attach the engine to the transaxle and lower them onto the motor mounts. Then jack the car up and pull the dolly out, mount the rear wheels & hook up the lines, bleed the brakes, wire the engine stuff and start it...

then lower the clam back down, bolt it on, plug in the lights, and go for a spin.

I know I could do it all alone but, damn, having a dude whose actually built a couple of these—even just standing back, sipping a brew, pointing and laughing at me—could be a big help.

So hold that thought. Should be getting to this point in a month or two (depending on the paint situation). I'll put you up if you want to blast down here for a weekend.

Lane: go to the Google. Type into the search box: barber pole vinyl 550 spyder
