i have a tatara nodachi in black.  i've used it several times with no problem.  the last time i took it apart and tried to screw it together, it stopped screwing about 1-2mm before becoming tight.  i have tried blowing out the hole and cleaning the screw but nothing has helped.
has anyone else experienced this?  any suggestions?

It sounds like you cross threaded the head. This happens when the handle is threaded into the head crooked. I would try to put some machine oil into the handle and gently try to screw the handle on. Also check the threads on the head (stud). If they are ok and all fails then you might have to re-tap the handle threads using a tap and a #19 drill bit. Finally try using another handle and see what happens.

Or....throw that nastiness away! Haha. I swear I am the only face on the planet that didn’t get along with this razor.

Try a different handle is a great idea.

It's definitely possible that you cross-threaded it, but it's pretty tough to cross-thread a razor to the point of damage so it could be some grit or material in the handle. Twist the handle onto a q-tip. Don't jam the q-tip in, but rather turn the handle on like you were threading it on. This is a good way to clean out the threads. Also take a close look at the threaded stud and check for damage. Like said above, also try out parts from other razors to identify the problem.

thanks everyone for your suggestions. i've tried machine oil and gently cleaning with a qtip. it's gotten a little better but still won't completely tighten.
can i try soaking it in vinegar or will that ruin the cerakote finish?

you can try twisting the handle on the cover without using the stove. this will allow a little development of threads into which sand or metal chips are likely to fall.

Some additional information might help. Have you inspected the “male” threads on the top cap closely? Do they provide any clues? Are there metal bits in the threads? Do the threads appear damaged at all? Next, have you tried shining a light into the handle? Any gunk or metal bits evident? Have you tried tapping the handle, with hole down against a non firm surface? (A plastic cutting board would probably do). Don’t use too much force. Have you probed the handle opening with a toothpick? Try holding it with the threaded hole down, and run the toothpick around the hole, probing gently. Any gunk fall out? Next, you can use an air compressor with a “spray” nozzle to blow gunk out of the handle opening. I’d do all these things before trying any “mechanical” steps aimed at solving a problem not yet fully diagnosed....

Also, WD-40 is a useful light solvent/cleaner tat might work. The spray force alone may free up gunk that got jammed in the handle. (Don’t wear nice clothes and stay away from the interior spaces of your household when trying this).

If you need, can lend you both a tap and die in the appropriate size.  DO NOT use a drill or you are well and truly screwed!!!  PM or text: 770.597.4646

razor comprises handle, cover and plate.
you take the handle and cover.
twist the thread several times.
then blow with your mouth or clean with an ear-cleaning stick.
add grease and twist again.
so that the stove does not interfere, you do not install it on the cover.
