Hello All,
Happy Hollidays all. Today I started my Mechmate project! Its a 5 x 10 4 axis model. My first build took months to complete and minutes to cut appart but in a 24 x 24 shop I needed the space. I gave up with time lines so it will be finnished whenever it happens. So far I have a 90rv pds colombo spindle (3 phase 5hp 280v)and a Sherline rotary table with chuck for the 4th axis. All other components are what Gerald recommends. Thanks Gerald for the plans. It sure makes life easier with a group behind you to help with ideas and pictures. I will update as time allows. Also thanks to Heath for the group buy on laser cut parts. Take care all, Tim |

A few more parts.
|
Tim,
Looking good. Will be nice to see some of my parts being built up! :) |
Index Head
What is the part number of that Index head? Where did you get it? and how big is it?
|
Welcome and update on the indexer would be nice.
What is that white stuff on your Jeep? I am wearing a T-Shirt outside!!!!:D |
Hello All,
www.sherline.com is were I found the rotary table and chuck. Its smaller than what I had wanted but the price was right and its good quality. It should be a fun addition plus there will be a plasma torch quick mount (taken off the old machine) as well. Heath I'm going to wait untill the table is done before I play with the laser cut parts even if it kills me. The control box is half done now (pics to follow tomorrow) and I'm still waiting on the racks and v bearings. I'm told tomorrow will be a balmy -5c almost tshirt weather but its always warm and sunny inside the shop! Will update later Tim |
Nils, stop teasing. :) Like Tim said, up here in Canada anything above 0C (or 32F for you US guys) is almost Tshirt weather here.
|
Warm enough for a swim?
|
Nothing better than sitting outside in a snow storm in the hot tub!:D
|
Nils,
Actually there are quite a few clubs that call themselves "Polar Bears" and they delight in going for a swim (a quick one at that) on new years day or some other day in Jan or Feb. They cut a hole in the ice and away they go. Not for me though. Maybe if I came to visit you I would go for a swim in Florida. :) |

A quick mock up! Still allot of work to go before assembly but its a start.
Tim |
Tim, is that spindle in your pic for ATC (automatic tool change)?
|
Yes it is.
|
|
Its a PDS Columbo RV90. I phoned direct to the company via their website. As for the tool holders, there your standard "Fork" style. They will be mounted in a rack at the end of the table with the index table setup.
|
Tim,
More pictures on the tool changer. You will be the first tool changer on here. |
Tim,
This is very interesting. We are also looking at the PDS Colombo RV 90/22 spindle for the ATC feature. We are curious which VFD you will be using? We do not have three-phase power in our shop, so we will need to use the 10 HP Delta 10/230B VFD to input single-phase 240 VAC and output three-phase power to the RV 90/22 5 HP spindle. Thanks, Jeff |

Thanks for the info... Hector |
Hi Tim,
How much did the spindle & Vfd cost you, looking forward for your detailed info Vishnu |
Vishnu,
Last time I talked with Tim, I think the spindle cost him a truck! ;):eek: |

Hello All,
I'm way behind in posting so there will be a few today. To give a little bit of background, this was my first machine. It was modded all the time then I tripped of this website and the rest is future postings. Tim |

This was the updated control system for the first machine. It will be modded for this one. Its a $50 p3 computer with a Antek power supply. The control system is a breakout board with individual controllers that will have Gecko 203v's on them.

I have a abrasive wheel cut off saw. I have had many over the years and have been disappointed many times with cut quality. Well I saw a Carbide tipped metal chop saw on tv for $400 and that gave me the idea. I picked up a 8" metal cutting blade at the local hardware store $75. I found my first chopsaw that was on its last legs put the saw blade in it and these are the photos. Its a very easy, smooth cutting. Not allot of sparks but allot of hot metal chips flying around. I'm working on a jig to cut the rails using my circular saw. I'll post the picks when time permits.
|
Just be careful of the blade and saw marriage. The blade you are using is designed for a very specific 5000 RPM and a saw designed to recover those "flying chips". You might want to check the RPM of that chop saw. I have a similar set up, but for those watching from the seats should be aware of the RPM's and hazards. I don't want to be an alarmist, just caution.

For the VFD I picked up the Delta VFD075B23A
(Input: 200-240 V, 50/60 Hz, 3-phase, 34 A Output: 33 A (continuous), 0.1-400 Hz, 10 HP). I told Todd what I needed and what I had to use and he put together a package. It wasn't cheap. The tool changer. . . . . :confused:. . . .O.K. I have a basic idea of what I want but I'll hangout at cnczone or mach3 forum and see whats better. The more I look around the more Idea's I get. I'll start to think about it more as the time gets closer, but for now I'll concentrate on just getting it running for now. For dust collection I built the cyclone system that was online. All the parts were cut out on the old machine. I guess I'm up to date for now. Just finishing up welding the legs. I'm hoping on assembly of the table on Friday. Tim |
Quite correct Sean, Its a death machine. Its 2k over what the blade is rated for, but I just can't stop using it. I looked around the shop to see what else could kill you, I think I'll just add it to the list.
Thanks for the heads up. |
You might inquire about a router speed control ($25) to put on that saw .... not sure if it will work or not. The one that plugs into the wall and the tool plugs into it. I think it needs to be a brush type motor, my chop saw is.

I'll have to move this over a bit more but I think it will work well here. The last bed rail will have to move too I think. Any other opinions/thoughts/ideas on this 4th axis?
