I've been putting off my steel order because they need to be cut the same day they come otherwise they won't fit in the garage, so I was hoping someone can help me determine the X length, I am using two Z slides, one the spindle the other a pneumatic drill about 14" apart. I just want to varify that I'm measuring correctly, do I add the 14" distance along with the 600mm to the X?
I also would like to list my material weights that I chose, please let me know if they are way overkill or not. Keeping in mind I plan to cut aluminum plate with it and the four walls will be bolted to each other and the cross bearers bolted. X beams 8x18.75 (roughly 14ft long?) Cross bearers 4x7.25 3 legs of c6x10.5 welded to X beam supported by 4x2x1/8 tube. gantry tubes 4x2x3/8 Z slide: 3/8 tool steel with the 2x1x3/16 backing Last edited by Father-of-Ash; Thu 11 June 2015 at 15:38.. |

Sorry...rough sketch.
Any recommendations to this as well? |

Some progress last night,
Y-car jigged and welded up & motors tuned. Can anyone tell me how much clearance between Z slide tube and spider plate? |

Hello all,
I'm getting ready to order some hardened beveled washers, cheapest I'm finding so far has a minimum quantity of 200 for $110, is that a good price to pay? Is malleable ok to use instead of hardened(F436)? |

Why hardened? I have 49 malleable square for 5/16 bolts; PM me with what you need and you can have 'em for shipping - or less if the shipping is trivial. I'd like to hold onto a few for odds and ends. I just looked; I used exactly 16 on my MM. Or, you could check out mcmaster.com - they've got them in small quantities at better prices than your 100 lot.

Brad, thank you for the kind offer but I am planing on using 1/2 bolts...I'm going to check McMaster now.
Thanks |

Hello all,
metal is in and I'm about to start cutting my beams but my head is still not 100% wrapped around whether I have my X dimensions correct. One of my concerns is the offset of the spindle, it is more than 4 inches offset looking at 1010 300...does the 600mm addition of the X compensate for whatever position the spindle is in the Y car? I've been reading but can't find much to clarify this, every time I sit to read I get carried off on another subject of the build ... Bilal Last edited by Father-of-Ash; Sat 20 June 2015 at 19:09.. |

The + values add the correct amount for the gantry. As far as spindle placement to the spoilboard, that is dependent on the crossbearer locations.

Pete, Thanks again for the quick reply.
So if my cutters are equidistant from the center of the Y-car, I can just add the distance between the cutters to the X beam length along with the 600mm and center my cross bearer layout to the X? |

Trying to follow your question but am having a little trouble understanding the exact information you are looking for.
|
#101
|
|||
|
|||
Just want to make sure I'm doing this right ...mainly concerned about both cutters reaching both ends..
|
#102

If you follow the prints for the length of your longitudinal beams,then it will be for that distance of cutting. I would add a couple of inches for wiggle room in my honest opinion. When looking at the prints you have to keep in mind which is the front and rear. I would have to open them up again but am fairly certain it gives the starting location for the first crossbearer. I did a bolt together build so it was critical to have the placement correct but if you are welding it doesn't take much to cut apart and move.

Pete, I think fasting got to me today. (ya thats a good excuse)
I think I confused myself once again but I found my answer here. and as soon as I read it, I remembered reading it a while back. Thanks again Pete, I'm going to have more questions on electrics for you, I remember reading about a safety relay for spindle you posted a wiring diagram for that looked similar to mine...I think. two more questions I wanted to put in, what are the thickness of the bushings behind the z-slide V-wheels? and does anyone have recommendations on the spindle mount for 4kw 4" diameter, or do you think the Chinese mount are OK? Thanks, Bilal Last edited by Father-of-Ash; Sat 20 June 2015 at 23:50.. Reason: two questions |

The drawing set allowed for only one tool offset to one side. If you want to be safe, measure the distance between the two tools, and add this dimension to the overall table length as calculated for a single tool.
Also, your table can then be symmetrical in terms of cross-bearer locations . . . . |

Gerald , Perfect! Thank you, I was still trying to be sure about the cross-bearers as well.
Just so I have the view correct in my head, when looking at the last pic above, when installed on the gantry/table the bottom left corner of pic is considered 0,0 correct? Last edited by Father-of-Ash; Sun 21 June 2015 at 01:43.. Reason: wording |

Hello all,
Just wanted to chime in, good progress has been made. I meant to post some pics before I went on vacation but didn't get around to it in time. I just got back and I'll post some soon. |

Hello all,
Before I forget once again, I wanted to thank Brad. I took his offer on those washers, Thank you very much. And thanks for those other parts Mike, much appreciated. I will soon post a link to pics of progress. Bilal |

What camera did you use ? Are those real gold bolts ? |

Hello All,
Thank you for the nice comments. Tom, I'm using the typical Lincoln 140. Decent welder but i wish it was a 220vac with higher duty cycle. Al most of the pics were taken with a Nikon coolpix AW120, the rest with htc M8 cell phone. The bolts are USA made, the zinc coating is definitely different then all other grade 8 bolts I've seen. they are from lexarindustrial.com ( moparman0110 on ebay) |

Hello all,
I got the rails cut and beveled, but not 100% to my liking. The 1mm gap in the center of bevel widens in certain areas, I'm hoping a final cutting pass will take care of that once they are mounted and leveled on the beams. Im almost ready to tear the machine down for paint and wanted to ask for opinions on the best way to prep it. I was thinking scrubbing it down with steel wool and dish soap then drying with shop air piece by piece. I called rustoleum but forgot exactly what they recommended, primer + self leveling paint of some kind. I'll be posting more pics soon. |

For cleaning use naptha(first choice) or denatured alcohol. Spray (cup) with paint used for industrial machines. All of these products can be found at a professional paint supply store, such as Sherwin Williams or Benjamin Moore.

Hello All,
That Naphta worked great Steve, thanks. Here is a link to some pics of progress. This industrial enamel takes forever to dry. In the meantime I've been shopping for some E-chain, so far I'm interested in 5.92" wide igus for $17 a foot. Anyone have some suggestions to other options? Also looking for some spindle mounts 100mm, the Chinese one is too wide for the Z. Is 12awg good for a 4.5kw spindle? too much? I'm hoping to progress faster now that the machine is almost ready to go back together. Thanks again! Last edited by Father-of-Ash; Sat 31 October 2015 at 19:50.. |
