Should I put a hollow grind on the blade of a LN Low Angle Jack Plane? If so, what degree for the hollow grind and what degree for the micro bevel?

To hollow grind or not? I think that if the h/g is your preference and suits your methods then that is the answer. In theory it is weaker, but I don't believe that is an issue.
Angles? Initially I would use the same angle that L/n put on the blade for the grind, and the same for honing. After some honings, you could raise the honing angle by say 5³ (and that has printed a degree sign , at least on this screen) and see what effect there is . That will buy you some time before the need to regrind and tell you whether to change angles or not.
I don't have a L/N low angle, I have the Veritas, and am currently making planes that work along those lines, so that is my sixpence worth.

Here it's the symbol for a cubed quantity. One that works on every screen is °
5°
Only downside is, on Windows you have to put it in in source mode.My goal is for my work to outlast me. Expect my joinery to get simpler as time goes by.
Or go to the character map. May need to go to Start, Accessories, Syatem Tools and find the map. I made a shortcut so it would be on my desktop.

I wonder if the character map method works when viewed by non-Windows users?My goal is for my work to outlast me. Expect my joinery to get simpler as time goes by.
If, by 'non Windows' you mean non Internet Explorer or those using Mozilla Firefox, yes it does work. If you mean Mac, I think there's a character map on those computers, too. I don't remember where it is, but I think it would be accessed the same way.

No, what I mean is, when someone not on Windows looks at your message, do they see a degree sign? In the message that started this thread, I don't know what means the original poster used to enter the degree sign, but on my machine it was displayed as a superscript 3, not a degree sign.
It's fine to use platform-specific features, but sometimes they look better on your own machine than to others reading your posts. A similar thing happens when novice Web authors dress up their sites with fonts, and specify them only by name, omitting things like weight and family. Then when anyone without their specific font views the page, it looks bad. Another similar error is to format with technologies that aren't available with all browsers, like ActiveX, without coding a fallback for other viewers.My goal is for my work to outlast me.

Mine showed the superscript 3 too. Maybe that's why he parenthetically specified that it was a degree sign.

...thus my response that the one method I know that works on all browsers, and is understood by all browsers when the message is later read, is ° :-)
happy happy degree degree °°°°°°°°°°°°°°°°°°My goal is for my work to outlast me. Expect my joinery to get simpler as time goes by.
John, fwiw, I am using Firefox. When I hit and hold Alt and type in 0176 I get a degree sign, but you get a cubed sign.... dang, from now on I'm just putting "deg" after. °°°°Philip Marcou

Philip, are you using the keyboard number or the keypad numbers?ASCII works with keypad numbers, not keyboard. (Might make a difference that mine is set to "United States - International".)Regards,Leon

Why not ask LN? Thom will tell you: he has answered email from me about his planes, and always seems to have a pretty good reason and explanation for what he proposes.

If you don't think too good, then don't think too much...
Are you useing a high angle blade, as a smoother, or low angle as a block plane was originally intended?
Low angle, I like a hollow grind, just fine, although, I seldom do that. For no particular reason. I just don't. 25° suits me for trimming endgrain on moldings and such.
As a smoother, I think you would defeat some of your purpose with a hollow grind. I like 35-40° for that.
