Cam Degreeing -- Need help please! (Video inside)

[KicknAsphlt]

To those that have degreed their cams in, I'd love to hear your inputs/advice. The embedded video describes and shows the issue I'm having, and I'm in some serious need of help here. I've watched the 'Super-Trick' video and searched/asked on here before, but there's really no good visual references/advice on how to do this properly. Any help that you can provide is greatly appreciated, this is one of the big items on my to-do list in order to get the motor running.
Thanks again in advance!

Need to set the dial indicator on the cam lobe top.

Really? I could've sworn IJ told me it sat on top of the shim/bucket....of course, this was 3yrs ago when I was originally supposed to do it...lol.

Other vids on youtube...

I've checked other vids on youtube -- they demonstrate the process well, but nothing that really shows proper orientation of the dial indicator on the shim/bucket; besides that, most are of V8s...lol. Here's the link to my original thread 2-1/2yrs ago.

Yeah, you need to get on top of the bucket. Get a long probe or use a test indicator.

All I have is what is supplied in the Summit degree kit (shown in video).

Sure you're on the shim with no interference? Indicator OK? Are you preloading it? Indicate the lobe and see if it repeats.

Update: I removed the beveled tip from the dial indicator and have it sitting on the edge of the bucket. I went back and used the piston stop to get a definite and accurate measure of TDC (rather than guessing by looking at the keyway on the crank pin), and I also have the dial indicator positioned so that it doesn't rub the cam shaft or interfere with the lobe path.

First pass after rechecking everything showed the valve at .050 @ about 5.5* BTDC. I tweaked the cam so that it was exactly at 6*, then made another pass, making sure that the dial indicator was indeed at zero, no binding/interfering, etc. at TDC. My next pass showed the dial indicator going to .047 @ 6* BTDC, and hitting .050 at 5* BTDC. Again, tweaked the cam gear to correct and brought crank back to TDC. Verified dial indicator again, then made another pass. Same deal, .047 lift @ 6* BTDC....I officially want to start breaking things now.... I'm trying to upload another video to show this current run, but my mobile Youtube app is also being retarded....so it may take a while. *grumble*

I don't get it. What's the problem?

 

[KicknAsphlt]

Updated videos - accidentally pressed the 'stop' button before I was finished, so the 2nd video in this post is the tail end of the process.

Did you ever solve your problem?
If not, are you completely sure that the cam lobe is not hitting the indicator during rotation?

A friend of mine taught me a trick when you don't have a slimmer indicator tip. Take a piece of TIG welding material and attach it to the tip with shrink wrap.
Then you can have it in line with the valve shaft
