HAAS VF-1 Rebuild
« on: August 07, 2013, 11:41:19 AM »
Last night Simply7 asked me to get the dimensions of a screw for the Big CNC.
It is a 1/4" 10-24 flathead with an 1/8" hex socket.  It has a standard countersink of 82 degrees.


A picture should be attached but I don't see it in the preview.  (some day I will figure all this stuff out)

Announcing the  CNC hackathon!!!   This event will run from the 23rd through the weekend until we have a working and fully assembled HAS CNC machine.

As you can see Dave has got the dimensions for the screws we need for the tool holder. I'll order those this week so we will have the neccessary parts.

If you have worked on the machine previously and are aware of other parts that we may need please post here with any info you have and we can try to get them before the 23rd.

Pocky has a worklist of some things that need to be done and we'll work on those things as well.


This will be a Familab member event only, and I'll bring doughnuts.

I have the new screws for the ATC. The cap head ones, not the really small ones. I am trying to get the smaller ones, but they are hard to find. Fastenal has them, but they need to be ordered.

Chorca, I've found the small screws through grainger, but it has to be ordered in quantities of 100. (27$) Is Fastenal any better/worse?

Have you tried McMaster?

Yes, and they had some that were close (philips head, not hex). But I hate to use philips in this as there would be a chance to strip the threads and cause more problems.

Simply7, try mscdirect.com as well. Sometimes if mcmaster doesn't have an item, msc does. Both suppliers are very similar, and I equally order from both.
Both have hubs out of Atlanta, and usually delivered the next day.


For instance, mcmaster did NOT have the plastic for the eyes on my last project, and msc did  ;)

Mike found the part numbers for screws so I order them. Mike also mentioned that we need replacement windows (polycarbonate).

 Does anyone know what size they were?

We'll have to measure. Not sure if we ever did that to begin with. We can use the old doors in the meantime, if we have to.

Got the measurements and have ordered the screws and polycarbonate (grainger's impact resistant poly).  These sheets will need to be cut and then heated and formed with two angles (same for both sheets).

Anyone have experience with this that wants to jump in?

I'm pretty sure P47 knows how to form these panels. Pat?

In the past I've used nichrome wire for larger jobs, and a heatgun for smaller projects. It pays to make a bending jig (or something similar) as see in this video.
DIY: Nichrome Wire Acrylic Bending Table Tutorial
To use the wire we would need, some thick nichrome wire, wood, aluminum channel and angles, and some hinges, etc. The lab has a variac.
Spare plastic sheets, or at least some to test.


Could try the heatgun and bending it over the edge of a tabletop with a clamp on the top... it might work . I helped Dan do something like this. Though the length wasn't too long and the plastic wasn't too thick it did work pretty good.
