LOL I wish I had that kinda luck. I'm managing so far in terms of getting things reconditioned but the assembly will go a lot faster if I had the help. Oh well, I suppose I'll keep at it and try to get it done. Oct 15 is a deadline I've set for myself, not many weekends before then :( I'll push it further if the weather holds up.

No reason to rush things now.  It will just increase the chance of mistakes and half-ass-ed-ness.

Question for Jerry H if you're still subscribed or anyone who has rebuilt gauges. I can't PM for some reason  >:( >:(

Is this a good substitute for the now elongated gasket in the gauge bodies?

Gauges are nearly done, new lenses, crimp rings and faces. Not happy with how dull the rings are, will polish them up tomorrow. Clever packaging from Marcel ;) Pic 2 is without flash.

Pipe tank for zincing large parts didn't work well, too close a proximity for proper electrodeposition. Had to steal my wife's cookie carrier and do the brake rod half and half at a time. Mine was in bad shape, bought a used one that showed up in much worse condition, so I just hammered mine to as straight as possible. The long bolts fit in just fine.

I know what you mean about the valve cover. They look so much better in person than in a picture after polishing. Mine is only about 1/2 done and I haven't set my bench grinder up for polishing yet. I have the wheels but it's kinda back burner right now. You have really been pumping out the polished parts as of late. I can appriciate the time consuming work that goes into it but the finished product makes it all worthwhile.

Thanks! I will take some pix out in the sun during assembly. This was surprisingly easier to buff, sanding is another story. The screw recesses were my concern, but half inch felt pads fit perfectly in there. Also, I started with a new set of wheels for this one just to get in between the grooves nicely.

Cal, did I miss a spot?  :P

One trick to get the photo right is to put the item on a white background and take a photo with and without the flash.

I didn't miss yours, just continuing it. Thought you'd accept my reply as "prod understood". Bits and pieces coming along great.

Got your PMs. As soon as I get home (stuck in FL since last Monday tending to Mum) I'll get on to it.

Yeah when I said I didn't have my wheels set up yet I meant that I did 1/2 of my valve cover with the Dremel! There are many different shaped  pads for getting into the tight spots but I need to get my bench grinder set up for the wide open parts to save time & effort. A few years back I did a couple of upper triples with the Dremel and although it took awhile they sure came out nice.

Got word from JMR, head is done and will be on its way home soon! Can' wait. First available warm and dry day after it arrives, its gonna get painted, baked and safely packed away for winter hibernation along with the rest of the bike. Getting too cold too fast and I just can't seem to find more time than just Sundays to work on it  :( Oh well, waited this long, might as well get it right for the next season.

I went with all new everything, so obviously the bill is humongus despite MIke's generosity, can't pay via paypal because of the fee so mailed him a check, more delay :(. To top that off, the weather is looking terrible so I may not even get to paint it. I've been sorting through the tons of NOS parts I've collected over the past year or so. I think I'm gonna box them together per fische page, that way come spring, I pick a box and start putting it together.

The serdi job was killer, biggest part of the bill. I had started porting the head already, but had Mike do it right when the guides were out so hopefully this will be bulletproof.

Nice! You should be very happy with that. Weather is one thing I have on my side here in Las Vegas. Going to be in mid 80's for the week and no humidity to speak of. I've been cleaning/ painting some small stuff, usually able to paint until mid November.
