I'm Back!
 

After a 2 month delay called...Life.:rolleyes: I'm back at the MM I have a cooled shop now and a 220 mig welder to use, so much nicer than multi-passes with the 110V. Made this yesterday.

Good to see you back.

Thanks, Pete.
Ok, I have built these using Metalheads kits and instructions in the forum.
I have a question though, is the odd looking plate for the Z axis? And do I have it in the right orientation for welding and assembly?

Thanks,

JD

JD, I cannot comment on the orientation of that style. I started with gear drives and modified the same ratio with a belt drive. Yours looks like a 4:1. Contact Metalhead for the exact arrangement as that design is after the revision of prints I have.

From your pictures I see 2 for the X, B, and Y and the other I would believe is for the Z. With the original prints, the X, B and Y had the same plates and the Z was different.

Hope that helps.

That's what I'm thinking , I don't see this plate in my prints, however I have seen it in pics mounted on the Z axis in the forum and there has been talk that there are 2 different z plates available. Just want to make sure I've got the right one and the right orientation.

Thanks,

JD

All Motor plates are done, Metalheads tutorial http://www.mechmate.com/forums/showthread.php?t=3354 worked like a champ. Now time to start grinding the rails.

Happy New Year, Grinding rails.
 

Happy New year everyone. I have found some time to get back at it, after a year of screwing around. Raising kids, training for new job, and moving to a different house. I have spent the last few weekends building my MechMate.

1. I have the table welded up and flipped, it took 6 guys and my wife to supervise. Still need to add some side supports on table.

2. Have all power wired from house and power wired from power supply into contacts etc, to feed break out board for control box.

3. Created a nice set of wrong height rails, and then re-created the correct size.

I am now finishing up grinding my rails (again) hope to be done today, and then ready to drill holes to attach rails.

Thanks,
JD

You're almost there.
Get your gantry up on the rails and watch it roll.
Then the excitement starts.

Hi Pete, I have to admit, I clamped my rails up and placed my gantry up and watched it roll back and forth for about an hour. However, had to get back to work, got all rails ground, switched over to a sanding pad with 120, (What a nice polish) finished the third rail and got about 2 feet on my last rail and my grinder made a funny grunt...ugh sound and got extremely hot within seconds. In other words it died. I will be picking up a new grinder this Friday.

Ha! Congratulations, having a grinder give up the ghost is a rite of passage. They really don't like the duty cycle that rail grinding puts them through.

Hey Brad,
It was honestly amazing just how fast it heated up after it gave up the ghost. I could not hold onto it with leather gloves, I just sat it on the floor and unplugged it...Sound of Taps in the background.

Looking good....;)

Every thing looking good. I'am just starting my rails grind, hope they come out as good as your look.

Mine did not come out that nice, But I probably not gonna be as accurate a cutter as most. But for what I do it's ok
