I love the zinc plating. What are you using to pre dip or "pickle" the parts before they go in the tank? Also curious about your electrolyte solution and anode.

After media blasting, I dip the parts in a mild acid for about 5 seconds. It's a concrete floor cleaning product. Seems to do the trick.

For electrolyte I'm using Zincate Concentrate from caswellplating.com. I also use their Zinc brightener. I tried some of the yellow chromate to copy the cadmium look but am not to impressed with it now, so I just do the zinc plating by itself.

You'll laugh at what I'm using for anodes. I didn't want to pay for the sheet metal style anode that Caswell sells. Figured I'd use them up pretty quickly. I looked at the marine anodes but wasn't sure I'd be getting pure zinc. So I ended up buying zinc bars off ebay. They claim to be pure zinc and are 2lbs each. Way overkill for size, but they should last forever and are giving great results.

The power supply/rectifier can be the most expensive piece. I found an old Lambda CC/CV on ebay that outputs 14 amps for $75 shipped. I'm really happy with it.

Damn those wheels look good! Car is looking great Dean. I can't wait to see it in person. Not to mention get a ride with the new motor (IMG:style_emoticons/default/piratenanner.gif) . Congrats on such a fine ride. I am sure your wife had a ball driving it (IMG:style_emoticons/default/driving-girl.gif)

Made a trip up up to McCall last night with the family. Flushing out any bugs before WCR and testing out a new external stereo mic for the helmet cam, what a difference. Still need to isolate the rear trans mount better so I don't get the downshift whine up through the body.

Dean it looks great. The whine I think is ring gear to pinion and you should be able to adjust it out if the pinion is in the right spot. Maybe Matt Monson will chime in, he is the guru, even though it is a suby I'm sure he has a lot of suby tranny experience also. Did you post the rear axle ratio it would like the rpms in the upper gears at their top when you get time, your tires are probably about 25 inches tall so it would be good for the 914 subt tranny guys to have as a reference. I think I remember the ratios are 3:90. 4:11 and 4:44 and maybe a 3:70

Thanks Charlie, I'll look into the adjustment, would be great to get it figured out. I noticed this in my last trans too. The final drive on this trans is 4.11, tire height is about 24.5, gears are 3.545, 2.111, 1.448, 1.088, 0.780. At 65mph I'm at about 2800 rpm. So far I'm really happy with it.

It is the side to side of the ring gear but the pinion needs to be in the right front to rear relationship first. The side to side is the bearing adjusters on each side. I think you showed the pictures of all this? The only way I know to do the pinion without the factory tool would be to make one up on a known good tranny before it is taken apart. I'm hoping for a taller 1st gear so if I can I want to try a 3:70 or 3:90 but thats also with a turbo motor so more torque.

Look at my "Suby Rustoration" build blog on how to set the ring preload (see post 85 of Suby Rustoration). Pretty simple really; but it means you'll have to yank the trans. However, unless you've opened it up in the past or changed the preload, you might need new bearings...

From my memory the backlash can be set by going in through the drain with a extension on a dial ind. The preload is the tension between the two side bearings. Set with a torque measurement on the amount of drag. Or a predetermined amount of fractional turns of the covers. Both are set with the side to side covers over the bearings.

Some pics from WCR. I got a chance to use the coveted WAS top prototype from Mark. Used it for the first half of the drive on Saturday, it was fantastic. We had the feeling of having the top off, light coming in overhead, but no sun or wind issues. It looked really great on the car, l didn't want to give it back. Mark had to pry it out of my hands, I'll be saving up for one of these babies.

And a few more... Hard to put into words what WCR 2011 meant to me and my wife Heidi. The event and a lot of great people in this club inspired me to get our car finished. Bottom line is it would have taken much longer without the goal of making it to WCR. There couldn't have been a greater way to celebrate getting the green machine on the road. Thanks everybody!

I just found my replacement Fuchs for your wheels Dean. Got a set of 16x7 front & 16x8 rears that should be at my house tommorow. So glad to get another set. I love 5-lug Fuchs on 914's (IMG:style_emoticons/default/drooley.gif) . As good as they look on your car. I won't cringe every time I see them now (IMG:style_emoticons/default/smile.gif)
