Part 1/2: • How Everything Begun: ...
This is part 2 of the two part compound slide rebuild series. I made a new acme thread spindle and accordingly a new leadscrew nut with adjustment feature for minimizing the backlash. Along with some smaller parts I finish the compound slide in this video. From part 1 I didn't expect the project to be so elaborate in the end. But there where some unexpected problems occuring with the bearings. Luckily everything went just fine in the end and the result I got is really satisfying. The compound slide moves so extremely smooth now and the new made adjustable backlash nut works so well that I measured almost zero backlash on the whole assembly.
I hope you enjoy this video.

Great video, great build. The idea to install socket head cap screws that you turned the head down to allow placement in the end of shaft so you could access with an allen wrench was great idea. Looking forward to your next video. Thanks for sharing.

Дружище, при регулировке задней бабки обрабатывая до кулачков, используй безотказную формулу. Диаметр больший минус диаметр меньший разделить на две длины. Получишь величину смещения задней бабки. Сместив её с помощью индикатора не меняя положения и желательно не трогая фиксатор пиноли,получишь снайперский выстрел. Если обработка ведётся не на всю длину то формула немного меняется. Точно не помню но по моему вместо длины нужно подставить разницу длин. Но первой формулой пользовался неоднократно. Работает как часы.

Das mit den Lagern ist ein Grund für mich, immer Lager von SKF zu kaufen. Die sind zwar teuer, aber wirklich gute Qualität. Industriestandard. Da liegst du immer innerhalb einiger Tausendstel Millimeter. Beim Gewindeschneiden, auch bei Trapezgewinden immer Schneidöl nutzen. Der Unterschied zu normalem Öl ist wirklich spürbar. Rändeln immer mit langsamer Drehzahl (zwischen 150 und 300/min) und auch hier immer Schneidöl nutzen. Du könntest versuchen mittels Stift und Nut deine verstellbare Mutter über eine Feder quasi wartungsfrei zu machen. Die Feder drückt beide Muttern auseinander, sodass du immer spielfrei bist. Kenne ich von einigen Herstellern von Drehmaschinen. Kannst du ebenfalls am Planschlitten machen. Nur ein paar kleine Tipps von nem Mechaniker mit knapp über 35 Jahren Berufserfahrung. 😊 Ach ja...

I like the hex in the end of the spindle as you can now power feed the compound slide to get a nice finish on taper turning by using a ball end key in a cordless drill which will give you variable feed speeds. the back lash adjustmend is very good too.

@jimmyfleebot 4 месяца назад

For when you remove the handle, a thumb screw with internal hex driver that aesthetically fits the other knurled surfaces would really finish it off. You could still retain an internal hex on the outside of the thumbscrew, incase you need extra torque during machining but I doubt you'd end up needing it that often

@GaisaSanktejo 3 месяца назад

For future reference: your machining and cutting that acme thread on the brass parts caused the metal to work harden, to resolve the "crunchiness" you need to heat treat the brass to remove the hardening... Also, I would suggest cutting the thread before machining the rest of since a fair chunk of that first part looked VERY thin and I was afraid it would snap off while trying to cut that thread. It could also allow you to hold it on some of the acme rod to keep the thread centered on the parts 😉 I like your making a bottoming tap as they're called, but that blueing had me concerned the temper on that tool was damaged, which isn't a concern for soft materials like brass etc, but could be a problem if you wish to use it for steel... if necessary, that could be easily resolved with a little heat treating Other than that observation, FANTASTIC JOB!

Just a mildly pedantic observation - @0:35, that is not a spindle, it is a lead, or feed, screw. A spindle's primary function is to... spin. Whereas, a lead screw's primary function is to... um... "lead" (ie, move) something... :) Pedantary aside, awesome upgrade!

for the nut just one drilling through the topslide to the middle of the nut. same with the screw. slides i think you would be better doing them separately, it would be a very complicated array of drilling passages etc to do a "one shot" for both slides.@@WeCanDoThatBetter
