Thanks handleman, interesting discussion!

Exactly for this purpose.

Are there any? Preferably free/open-source.

Thanks guys [2thumbsup]

Does anyone know whether aviation incandescent light bulbs used for various cockpit lighting are special in any way? How precise do voltages need to be? How sensitive are they to ripple/noise/spikes/etc in the power supply?

Thanks, hmm time to ponder.

I'll just draw it out.https://files.engineering.com/getfile.aspx?folder=f08b9683-9a02-4aad-b35a-d509a8bacbd3&file=Force_Diagram.jpg

The third post has a diagram of a side view of a gantry for a CNC Router and the forces upon it. https://www.cnczone.com/forums/diy-cnc-router-table-machines/205766-cnc-cad-posts-3.html Question is, the force arrows look wrong to me. Shouldn't the pivot point be point A in both directions of...

@DraftingMan thanks for the link but I prefer books and poking around first hand. I don't learn well in these kinds of settings. As they say - Tell me and I forget, teach me and I may remember, involve me and I learn. @Belanger Acquring standards is definitely on my to do list. Unfortunately...

I didn't know Machinery's handbook talks about any of this stuff! Will have to look into it.

Hi, I'm interested in learning GD&T and also Fits and Tolerances. What would be the best way for me to learn these two things short of going to uni? Books, online resources etc. Do I need to learn one before the other or are these largely independent?

Hi, Trying to figure out how to attach a wheel between two plates like this: https://i.ebayimg.com/images/g/iYcAAOSwFe5XxwA~/s-l300.jpg I don't want to use a bolt because the bolt and the nut would be adding width to the assembly - I'm trying to keep the whole construction as narrow as...

Thanks guys, some food for thought. I think I figured out the peek analogy Taylor ;).

Ah very good points that I hadn't thought of Mike, thanks for that. Glad I asked the question. Yep aware of redbird. What do you mean by 1-peek is worth a thousand guesses?

Hi, I'm building a recreational flight simulator. I'm no professional engineer and need some help with designing a base. Maybe one day, I'll put the simulator onto a 6dof motion platform so I would like to design the base with that in mind. How would you go about talking this task? How do I...

Hi, I'm trying to make a custom silicone rubber keyboard. I'm having a real hard time finding information that would be of use with this challenge. I am trying to make it such that the base layer is transparent although it doesn't have to be clear and then on top of this I need to paint or put...

Fair comment, I guess I was asking for pointers on where to read up on tolerances in general. Got a couple of leads so got the answer I was looking for.

Hehe a good sense of humor on this forum :). No, not trying to seal anything, not welding anything, not designing any punch presses and nothing to do with liquids. Just designing both static parts and dynamic parts and would be nice to have something other than a guess to estimate gaps. Just...

Hi Guys, I'm designing some basic things but I need some clarification regarding the gap that I should leave. If I have a cutout and then into that cutout I insert another part of the same shape, how big a gap should I use? If you add paint, the part that I'll be inserting will become larger...

Thanks Bumblyari.
