I have suggestions:
1. Do what Superman suggested and make it longer. As a minimum I'd recommend making it the same length as an ISO10 collet holder with its nut would be. I don't think that the...

I believe that all of Inteliteks's machines have cast granite bases and linear ways, so the rigidity should be there to do so. As you said, speed won't be great. You might want to give Intelitek a...
You're almost correct. All machines bend and settle, it's just a matter of how much. An important consideration of machines is designing their foundations, including feet that can be adjusted to...
Short answer, not really.
Longer answer - the maximum rotational velocity of ballscrews, and thus the maximum linear speed of the axis is massively increased when both ends are supported, as is...
You're at risk of diminishing your safety just so you can use the ESTOP button as a runhold instead of its intended purpose - an actual emergency.
The question is whether you can totally trust...
Other way around - larger particles float up over time. I don't that matters though - if you don't prevent migration with a binder you might as well stick to one size particle.

All the ISO collet chuck toolholders are specified at 8deg 17' 50" as noted before by vmax. ISO30-50 appear to have been superseded by the DIN standard DIN69871 that includes through spindle...
If you don't have a good flat surface to assemble your torsion boxes then the first consideration should be to get a good flat surface big enough to assemble your boxes on. Your wood will comply to...
Abrasive blade in a chop saw. Make sure the saw is plugged into a gfci, cut it outside somewhere some rusty water isn't going to be problematic, and use a hose to keep the rail cool. You want to...
I'd put the ball screw up top rather than extend the z forward. Just make sure that the nut to carriage connection is rigid - deflection there becomes backlash.

If the balls cannot circulate then that would accelerate wear significantly. Depending on the particular bearing system, the balls could be chrome steel or stainless steel. Same goes for the rails. ...
Just about any bog standard RTV silicone should work in most environments. Make sure your holes are clean (degreased), and that your bolt heads are covered with a small wad of cloth to stop them...
It's been a long time since I watched those videos. I can't remember whether he took measurements or not. They're linked above...

Good luck. Two of aramid fiber's properties are resistance to abrasion and resistance to fire. That is why you will find it used in bulletproof vests, and both firefighting and auto racing apparels....
Glass is pretty impervious to most chemicals, so it's a case of getting gunk and grease off without scratching or breaking it. Window cleaners are often ammonia-based, but another good glass...
Most linear bearing manufacturers specs that I've read seem to recommend an NLGI grade 2 non-molybdenum synthetic grease such as Shell Alvania EP2 or equivalent for general purpose use. Special...
Gantry machine? Right?
Are you using the ballscrews with encoders for positioning or are you using linear scales for position feedback? If the former then you want as little distance as possible...
I've seen that suggestion of clay before and I'm not sure that it makes sense. Clay is finely ground rock or dirt with traces of metal oxides. I don't think I'd want that anywhere near my linear...
Mc is a rolling moment, as if you're trying to roll the block around the rail axis. One side of the rail sees a radial load, the other a reverse radial load.
I assume you're talking about a...
What kind of airflow does a fogbuster need? How many SCFM at 90 PSI?
I wonder about urethane-foam filled carbon-fiber frames. Dealing with mass is a major hassle for hobbyists - you can ship carbon fiber parts cheaply and handle them easily. You'd need to pay a...
If you're absolutely set on that size than a gantry router style would be better.

True, the filling isn't going to add strength. It is going to damp vibrations leading to better rigidity. Resonant frequencies exist for every beam based upon its length and mass. If you are taking...
No, that wasn't it, although it shows a nice technique for vibrating the sand down. I remembered who it was. "This Old Tony". He's got some great videos out there, his style is very informative....
Polycarbonate all the way. (LEXAN is a trademarked brand of it.) 6mm is not overkill. You can caulk it into the extrusion to reduce the leak issue.
How much do you value your friendship, and what is the budget? I suspect from the nature of your questions that one or both of you will be disappointed by the end of this project and that will test...
Somewhere on YouTube is a series where someone built a gantry router doing exactly that with sand, asked it appeared to have worked very well. Sand is a cost-effective improvement to a hollow frame....
She's a beauty! Awesome job. How did you put the design together?
Is there any particular reason why you didn't use a colored gel coat on the mould before filling it with granite? You'd have...
I think you're going about this a little backwards and probably making more work for yourself without appreciable benefit.
Your square tube will not be flat, especially after welding. Your flat...
I'm not an electrician, but I believe that ovens require a dedicated circuit by code. Even ignoring that, the physical connections would be difficult - one does not simply wirenut a 6 gauge wire.
