Hoss's G0704

[jdurkin]

Like I mentioned above, those diamond hones are very fine and flat and are
good for making sure there aren't any burrs or high spots.
Might also want to check the gib strip is still flat on a surface plate.

Cheers for the input

Hey hoss
Did you ever upgrade your aluminum spindle sleeve to steel? I bought your prints a while ago and am just getting around to making the parts. In your video you mention the ally is temporary. Obviously I could have missed it.
Thanks
Pete

Nope, the aluminum one is still on there going strong no problem.
Put 1.5 HP motors to it and extreme milling tests no trouble.
Steel seems unnecessary now after 2 years.

Thanks hoss. Appreciate all your help in this forum and dvd's. I don't post much but read a lot

Got my mill today, 2 weeks from the time I ordered it,- one week to ship, one week waiting for ups freight to ship it all over the country and then finally to me. It seems to be in good shape, I have not run it yet. Plenty of cleaning to do first. On another note because I apparently DO need another hole in my head, I ordered a H1 complete kit from SeeMeCNC.

1. think your seeing the holes in the table, no holes in the ways at that point.
2.probably just sharpie marks you're seeing.
3. booboos, changed my mind, made marks where the 2 locks made contact where I was going to have 2 thru holes for oiling, changed to
one in the center.
4.can't drill a hole thru the angled gib into the oil hole from the inside,
much easier to do it my way. Plugging was just for the rear hole since it's source
comes from the side of the saddle.
5.not critical, roughly centered. used 1/8" drill bit for the oil holes,
1/4" thru the gib strip to allow for adjustment and provide a little oil reservoir.
Be sure to deburr all holes and clean it thoroughly, those diamond hones work great
to make sure there are no high spots.

Thanks for all the great answers. Things are getting much clearer.

That must have been a tough drilling exercise making the 1/8" hole from the side of the saddle. How hard was it going down 3.5" and trying to hit a 1/8" diameter target?

I assume that you made oil grooves on the bottom side of the saddle as well, for a total of four oil grooves?

Not too much to do on the 0704 that I haven't done already but I'll think of something.

I've got some ideas!

1. trunnion table
2. 4th axis engraving onto cylindrical objects
3. detailed build of a control panel along with schematics
4. detailed build of the power panel (stepper drivers, power supply, etc) along with schematics
5. A video (or videos) following a part from idea conception to cad, then cam, next to part/fixture holding and tool offsets/fixture offsets, to setting the spindle to X0Y0 (showing electronic edge finder?), then to air cutting (verification of no program bugs), and finally cutting chips.
6. High speed spindle attachment
7. Surface grinder (G0704 should be way better than the X2 experiments you made several years ago)

If the G0704 is basically done, does that mean you're going to put her to work making money by machining kits?

Yes 4 oil grooves in all.
Boy those are some good ideas, guess I'm not done after all.

Maybe time for scratch built H0804.
Really though some in depth electronic hookup tutorials would be really cool.
BOB wring ,steppers, stepper drivers,VFD's,relays,etc. I would be all over that DVD.

[Mad Welder]

Yup count me in on the order waiting list for an electronics DVD tutorial too

[hoss2006]

Not likely to happen, I'm no EE so I'm not comfortable giving that kind of detailed electrical advice.
I won't pretend that I am, I just follow what the manufacturers of the devices recommend, they would know.
My electrical and electronics training was for aircraft.

Hoss,

Did you mill grooves in the Z also?

I think I am going to go with a regular H pattern so that way I can just do it at work.

No, by the time I got to the z I wasn't able to use my mills downstairs so I used
a disc grinder to cut a half moon groove just across the width of the way where the thru hole comes out.
Will spread the oil when the axis moves up and down during the warm up program.
