Thank All Of You
Over the past few months I have bugged you with quite a few questions. I had one prior build some 15 years ago and with your help I was able to turn picture one into picture two. It should make a good gift for 14 year old boy whose school colors are red and blue. I started with some take off rims and a box of odd parts I had laying around. I added a $40 Nashbar frame and some assorted parts I ordered. I am pretty happy with the outcome. I have one more to do, the next one for myself.

Beautiful. Looks nicer than what most stores out out. The color coordinated tires and radial front wheel make it really special, a great conversation starter.
Since perfection is considered bad karma in some circles, I'll point out the flaw. The rear brake cable loop is too long, trimming an inch or two would make a better run with less bends.

Looks great...
1. Slide saddle back 1cm so that it is centered on post.
2. Swap to a 1cm shorter length stem.
You have just a tad of tilt-back of the saddle which is great - means you are not forcing your body to rely on the hands for support. (That leads to hand and wrist pain...)
Other than FBinNY's housing suggestion - looks good overall.

Thanks for the pointers. Once I give it to him I'll make the final fitting adjustments. I still don't have the rear derailleur dialed in perfectly. I cant seem to get it just right in second gear. It clicks and jumps a little. First is better but not perfect. 3-8 work flawlessly.

I agree with FBinNY that the rear brake cable run is a bit too long but the saddle position and stem length will be better set when the actual rider is available for a fitting.

Anyway now that I've unloaded the peeve of the day, you probably need to lower the derailleur via the B screw. High derailleurs cause problems on larger sprockets because the pulley is riding the sprocket through the chain, or nearly so.
Shift to the problem sprocket and look at the juncture of upper pulley, chain and sprocket. There needs to be daylight between them and roughly 1 inch of free chain running from the pulley to the sprocket. You can manually push the RD down a bit to see if things improve, and if so make it permanent by tightening the B screw.
With deference to HillRider, I doubt the limit screw is a factor, since the problem manifests on the 2nd sprocket where limits have no effect.

At this point it's moot, and can wait on fitting, but I'd attend to the brake loop, and dial in the derailleur adjustment, since neither is rider determined.

My thinking was (and I agree, which cog is #1 and which cog is #8 was not clear) is that the shift from the smallest to the second smallest cog is a problem. I've seen that happen when the high limit screw was too tight or too loose and the "spacing" between the cogs is then off. The same problem can occur between the largest and next largest cog if the limit screws are off. That's why I prefer to set them with the cable disconnected.

I often see chains or derailleurs overshift into the spokes because the low limit was adjusted while shifting via the lever. The RD takes the low gear position based on the index notch, and no one notices that it isn't up to the limit, and one day it overshifts (oops).

True, final adjustments are always to the rider, but for presentation things should be set at the neutral starting position, ie. saddle level, to slight uptilt and centered in the post cradle. Also the post should be raised to what would normally be the right height if the frame was the right size. It makes the bike look more "right".
At this point it's moot, and can wait on fitting, but I'd attend to the brake loop, and dial in the derailleur adjustment, since neither is rider determined.

You and I both know the saddle should start approx. neutral...and close to proper height - with most dimensional changes being up front in the stem height, length and angle, and bar and lever and drop reach - and it is there that it gets pretty individualistic.
Of course, anyone reading a frame building and frame/bike fitting reference would discover this pretty quick.
