Not only would GFRC be far cheaper than granite, and lighter depending on the ingredients, you could route a form in which to cast the plenum layer. For that matter, one could integrate the base and...

Eric, please don't laugh, but I'd like to suggest you investigate using a type of concrete called "GFRC".

I have long been interested in Glass Fiber Reinforced Concrete, "GFRC", (but failed to...

Well, since you asked,,,,,,,,,,,,, your choice of text placement is really not pleasing to my eye. However you place it, "All gave some" needs to all be on one line, and "Some gave all" needs to...

Hello Shopbot friends:

Having worked as an electronics engineer in new product development for many years, it must be understood that any electronics with switching circuitry, (anything from SCR...

Thank you Brady! I always greatly appreciate your input. It would make more sense to put it in a sound isolating arrangement of some sort........ Unfortunately, this is in my basement, right...

Well, here it is, 7 years later,,,,,,,,, and my Roots blower is still sitting under my Bot.......... I am going to make various upgrades to my Bot this winter, and I'd rather have a smaller vacuum...

Hopefully I am not the only one who likes to find design inspiration in old sources........... And since this catalog is from 1897,,,, no CNC back then! Chuck...

Wow, that model of DC is amazing! Are some of the buildings cut out/modeled separately and attached to the base board, or are they all that way?

Thanks Eric for the added links to SketchUp videos. The sandbox tools appeared to be interesting, but from the short videos, it mostly looked like everything was geometrically based, and then just...

Thanks Eric. I had partially assumed Sketch-up was used because you know how to use it. And I did have the general understanding that Sketch-up is a very powerful general tool.

But it is of...

Hello Eric. I have never used SketchUp. But since you have Aspire, why didn't you just design the sign in Aspire? Aspire is a great design tool, and from what I saw in your video, SketchUp looks...

Daniel,,,,,,,, things aren't set up for me to take a picture, but I recall that attaching the foot isn't hard. However, I don't use the dust collection attachment, and maybe they both won't fit on...

Hmm, there seems to have been a fair amount of conjecture as to the original poster's (DC CNC) problem. However, he never did come back with good pictures or clarifications that would help those...

Brian, I have a PRT alpha, but I have just gotten done re-doing parts of mine. Though I am a dabbler, I will offer an initial comment, with the hope that someone who knows more will offer their...

Hello DC. I honestly couldn't figure out what problem you were describing, but after looking at your photo your issue became apparent. To at least start with a clear description of the problem,...

That was interesting reading Brady! Again, more things I had never realized. Thanks, Chuck

As but one of untold numbers of Botters who have been helped by Brady, I want to say thank you to him for his huge support to so many over so many years. Hopefully in the long run the comments made...

Looking at your first photo, I think things would have looked much nicer had you moved the eagle over to the left about 1/2"........ you would have removed "CHINA". Chuck

Thank you John. That seems like a logical solution to remove the excess space between the shafts and the sleeve bearings. Chuck

Hello Daniel. I tried using double sticky tape to hold down 1/4 thick, 4'x4' melamine sheets, on which I was doing V-carving. The double sticky tape simply didn't work for me at all. I should...

Thank you Kenneth....... I'll have to look at my frame,,,,, but it never seemed to me that mine wobbles much. Maybe I run things too slow............ Chuck

Hello Kenneth. I am still fiddling with some other parts of my Bot, so I haven't yet been able to test out my welded gantry. When you did your gantry welding, how would you rate the improvement? ...

Thank you Dave. I appreciate your positive feedback. Best regards, Chuck

Scott, please check your private messages. I just now discovered a private message you recently sent to me and answered that along with a comment on your new post. Thanks, Chuck

Nice work Steve........ hard to do better than the Texas seal on a pecan box.

As to the note on traffic on the forum,,,,, The only other related forum I post on is Vectric/Aspire. And...
