    Last update from me: IT WORKS!!!

    I tightened down the bearings even more today, and then hoping against hope I took the advice of Thermite from an old thread I dredged up. Apparently, in some...

    That's what I suspected. For a 1mm o-ring, you'll want a slightly wider groove, like 1.35 to 1.4 or so. That way, when the assembly is fit together, the o-ring has a chance to oblong itself within...

    Before you cut metal, I'm suspicious of your o-ring groove size. What size o-ring do you intend to use? How did you define the width and depth?

    As for cutting it, why couldn't you just interpolate...

    We have made some progress here, but there's more to do.

    I finished my homemade spanner, got the bearings tightened down some, and it made a big difference on the circularity. We're now down to...

    Shifter is a little odd, but clutch is still on the left, then brake, then gas on the right. Gear pattern is the same too, just operated with the left hand makes it odd.

    One thing that makes me suspicious is when a thread I've never seen before instantly has the "hot thread" orange icon showing lots of views and/or replies.

    Milland,

    Unfortunately, I'm not well set-up to take your advice, as much as I would like to. Without my lathe, I won't be able to make those plugs, and I don't have enough indicators to take...

    Alright, I'm stuck. I took a look at the carriage and saddle, and adjusting the gibs made a huge difference on the deflection readings at the carriage and toolpost. More work to do if I want it...

    Yep, I completely agree, since I used to work for a machine building company that specialized in microhole EDM. Smallest hole I was ever personally involved with was 0.004" so you got me there, but...

    Regarding the play in the blade in the locked position, whether that is normal or not depends on the lock style. Most knives with a lever lock on the spine of the handle will rock a bit, it's...

    OK, first of all thanks for the feedback and some leads to follow.

    I looked with a more critical eye at the carriage travel hardware, and it all still seems OK. That's good news. The other good...

    Yep, and all of those are slower than brine containing a surfactant.

    As an explanation, the dissolved salt increases the mass of the water, so it requires more energy to boil it. The surfactant...
