Finally got the welders up and running. Luckily i can always keep the breaker in the main panel switched off, so my fear of having exposed 6/3 laying across the yard wont be too terrible. I only need the welders for about a month, to help complete body work and get the cage door bars welded in, then ill wrap the wire back up:

Evidence it works, somewhat lol:



The two follow up beads i tried to lay, every moth in the building was like Oooooo! and flew directly into the arc. I got fed up and stopped, damn moths would not stop for nothing.

How about in that pic of the Weld Pro welder, I somehow missed the old ACCEL Honda coil sitting there. I haven't seen one of those in like 10-15 years!!

Before the dyno last year, i went to pick up a spare igniter and coil just in case... the accel was sitting there for $10 cheaper than the already crappy generic oreilly coil, so i figured it couldnt hurt haha.

Then like 2 weeks later, i went to the prelude external coil setup lmao so its just been sitting here.

I worked on the car a ton today.

Finished pulling all body panels, bumpers, splitters, side skirts, seats, trim plastics, rear hatch glass, tail lights, gas cap cover... ready for body work!

Also got the transmission out:

Crank out:

The Y8 crank specs perfect still. Might get it polished, and stored away.

Put the old bearings, rod caps and crank girdle back on the engine to check oil clearances against spec and old crank with a bore gauge:

20210605_002738.jpg

20210604_205328.jpg


On old bearings measuring at 6 and 12 o'clock, rod clearance is still between 0.0015 and 0.0020, and main clearance is also between 0.0015 and 0.0020.

Pretty much exactly the same as it was when i used plastigage last time i assembled.

Thought it was interesting that the main bearing bores are out of round by about 0.002 - 0.0025 at the shell parting line where crush pressure takes place. Ive never really measured bearing clearance with a bore gauge before, always used plastigage at the 6/12 o'clock positions based on OE service procedure.

Apparently this is normal after initially freaking out. There isnt really a published spec on this measurement in the OE service manual, but apparently this is something baked into the bearing design as well as the bore itself?

Crank is at the machine shop! 2-3 week turn around.

I did bring the crank to the crank builder to see about snout repair. He was weary of welding this snout, since hes aware of the steel quality in Honda's. He said short of welding the snout, re-heat treating it to relax the welded area and re-forge the assembly, re-nitriding it, and machining the journals to accept oversize bearings, he didnt feel comfortable JUST welding this snout and sending it out the door with his name on it.

He said the only reason Honda could get away with having the balancers engage only half the crank snout in this appplication is because of how well their crank steel is forged. No one else hangs their balancers that far off, and uses a tiny little key to clock it, and make it work for as long as it does. The only reason it works is because of how good the steel really is. Any significant heat caused by a torch or welding will ruin the strength of the snout.

That being said, i bounced the idea of adding the extra keyway steel into a cold shaped pocket to rebuild the wall for the keyway to engage, and he thought it would work. He said as long as the cuts stayed cool, and the balancer bolt didn't come loose at high rpm at any point, that it should last a long time with the loctite 660 lol. So, im gonna roll with that piece of advice.

Cage is still being built. Should be shipping out in about 2-3 weeks.

Pumps made it to Bad Guys. Should be about the same amount of turn around time, 2-3 weeks.

In the mean time, im ordering standard size bearings for crank and rods, and will run 10w40 of some type when all is said and done.

Got a spray gun mounted air regulator for better air pressure control:

Also a short whip hose for the air dryer:

20210609_202332.jpg


Pulled the seats out, and covered them to protect things from all the dust that is going to be flying around this shop soon:

20210609_212025.jpg


Stashed all the bumpers, rear glass, and related crap up in the rafters:

20210609_212103.jpg


Got the roof line at the windshield lifted back, and somewhat of a curve put back in it:

20210609_213104.jpg

Also hammered out the dents on the sloping corners back to somewhat of a curve. With some body filler, none of the big imperfections will be noticible:

Pulled these window trim pieces out. Every clip shattered in the process, but im going to re-black these pieces of chrome trim, probably with a rhino liner coating of some type:

New clips were cheap, bag of 30:

Also ordered new bearings for the main and rods:

Not much left to get! Pump is coming, cage should ship soon, crank should be done in a few weeks, primary focus is on body work at this time.

Probably start to plug the sunroof hole, the antenna hole, and start doing minor body filler spots as well. Not looking forward to masking off the car, its gonna take forever!


Oh, one more thing! I redeemed my credit from the withdrawn NASA event last year, and put it towards this year's Hyperfest event at VIR! It's the first weekend of October, should be a badass event. The days will start cooling off a bit by then, so me and the wife might just camp out up there if we can find a babysitter haha.

Hyperfest info if anyone wants to come check it out!



There is also another VIR event in mid August that i might attend as well, but we'll see how tapped out for time I am as the build draws to a close, once again lol... If i make it on the road before end of July, then i may register, we shall see.

I fucking hate how labor intensive and boring body work is Got the sunroof hole and the antenna hole plugged:

I'll TIG the panel butt joints slowly, moving fast and hot to keep heat concentrated and avoid a wide heat path, then let off quickly and move to another area, in effort not to warp the painstakingly "impossible-to-form-with-your-knee-properly" slight curve all the pieces currently take to the roof line.

It came out better than i thought it would, and with the whole gap bridged now, and the slight curve to all the pieces, its actually very strong. Cross fingers it doesn't warp! If it does, hammer time :)
