Yes, the automatic draining just prevents water from sitting in the tank for long term and it is a convenience. I doubt it does change the water content in the air. Compared to periodically manual draining. I never saw a Desicant Air dryer in Taiwan, they usually add a refrigerant cooler to the...

I have a "full" tank all the time. It is very warm and humid most of the time. The compressor at work has an automatic tank drain valve that keeps draining the tank for 1-2 seconds ever so often. I assume 20 l per day is our average water amount. We used to pour it out in the morning, but now I...

Rumor says filled filaments damage nozzles earlier. (possibly not too much issue) I was able to print some 0.7 module gears with the 0.4 mm nozzle. The gears on the other post look quite decent. I think smaller than 0.5 module the resolution of the belt drives becomes also an issue, even if the...

That is amazing, I have older PLA prints that just self destruct without any other reason than beeing old. Maybe because it is warm and humid all the time.

Used it long time ago for simple parts. That was not too frustrating, but the parts were simple enough. That must have been 15 years ago. And I used the models for 3d printing. At work Freecad is my GoTo software to open and look at 3d files from customers. This worked very stable so far and was...

Soo many questions :) Is the guy in the dark shorts standing in the water? (smells like photo montage) What are they fishing? Are you sure that is not called "hookup" boat? Fuel is cheap in USA, in Europe fishing boats look like this. And they are struggling to pay for the fuel. Is the...

I just sayin; as I mentioned before "3d printed gears are evil!" ;) Modelling mounting holes has the advantage that there will be a more solid "outside wall". What can possibly go wrong. Worst case it does not work at all. With a half decent printer there is not much chance of that. Removing...

I am not so sure, maybe it depends on what "a bit" means. (pacemakers, radio, grid reactions come to mind) Sort of yes and not. When the refractory lining wears down to the coil, I assume it can get nasty. I guess repairing the lining is on the long run cheaper than wasting the coil. Running...

I posted this a while ago. It is doable, but I think you should have a shaper or slotter of some sort for it. Slotting it with the quill of the mill will be possible but will take forever. https://www.homemodelenginemachinist.com/threads/how-to-cut-internal-gear.35851/ I would guess a 3d...

I doubt that the accuracy of the change gears will decide about usability of a "jacobs hobber" :) I guess there are more important things, like runout of cutter and gear blank. Stiffness of setup etc. For the change gears of your hobber you will probably get away using anything with the right...

If the addendum and dedendum are not right you can end up with rubbing in the inside of the worm wheel, (outside diameter of worm) and you might still have backlash on the tooth flank at the same time. Because the worm is touching the root diameter of the wormwheel the center distance cannot be...

I would think dedendum of the worm wheel is created by the addendum of the hob. If the worm and hob have the same addendum and dedendum, then there will be no clearance. I think the hob needs to have a larger diameter than the corresponding worm. p.s. contacting the manufacturer if they can...

Question is: How many sensors and I/O do you need? Make a plan, test the mechanics, arrange the electrics, then change program. -> Done! A3, A2, A1 and A0 are free. Digital I/Os 11, 12 and 13 are unused. Digital I/Os 0 and 1 might be used by the serial output during programming The memory...

What do I have to immagine when I hear "40 kg Servo"?

Thank you for the foto. (happy I remembered it correct) Next question pops up. Can we make this in the home shop? It is for sure not worth it, given the price. :cool:

Impatience as integral part of safety concept ;)? I can relate to that ☺️.

I would print some posters on the veneer with a vintage manual printing machine :), if I had veneer or a printing machine.

I use a serrated pulley, made with the same approach to push my PLA plastic into the 3d printer. It has a much smaller diameter about 8 mm. The teeth were hobbed into the wheel with an M3 tap, they really bite into the plastic. Pressure is applied with a plain bearing pressing the plastic...

I would find casting in the snow scary. 😮 Just sayin.

I often machine to exact size, pat myself on the sholder, take a break, get surprised that the part is undersized (yet again undersized and surprised). a) use sandpaper b) get impatient c) skim of the smallest step you can cut d) end up under/oversized and use Loctite :cool: At 0.003-0.004"...
