Welcome Yuri!
Looks like you are on your way. Keep us updated with photos, we like photos.

Welcome to this forum Yuri!

I see you are going to have quite a big X dimension: 4400mm [14.4 ft]. What is your Y dimension?

Good luck with the building of your MM. I like the clean W/Shop and new tools..

Thanks Domino, more photos

I am happy and nothing like a beer to accompany

Hi Yuri, Looks like you ordered a couple of extra parts?

YRD · #9 Sat 27 September 2008, 23:34

Hi Gerald,
Yes

The company that made the cut has a minimum value for the service. Approximately US$ 270.00

If commit any errors in the solder, can change the play.

What did you think of V-Roller chinese

Gerald D · #10 Sun 28 September 2008, 00:32

V-Roller chinese should be okay.

YRD · #11 Mon 29 September 2008, 07:33

In the post 9 reads "solder" read welding.

Problem of translation.

Yuri,
No problem, I knew what you meant, even up here in Canada!

Gerald D · #21 Thu 09 October 2008, 00:38

Ah, those tubes are at least 3mm thick, but still not thick enough to tighten the M8 screws really tight in a tapped hole. Are you adding something inside? Or, are you going to be careful with the tightening? I think it is okay for strength of the rail joint if the tightening of the screw is at half-tightened . . . . .

YRD · #22 Thu 09 October 2008, 08:44

Yes the bar of steel inside the tube, as project.

YRD · #23 Thu 09 October 2008, 17:54

How should I use for 28mm?
Use the blade as in the 1st or 2nd picture?

Thanks,
Yuri

Kobus_Joubert · #24 Thu 09 October 2008, 23:19

Hi Yuri, I think you have the wrong disk for cutting the rail down to 28mm. Your picture looks like a GRINDING DISK. You need a CUTTING DISK. I used a very thin one to cut done my rails. When you grind something, the setup in photo 2 is correct according to me....Correct for grinding the 45 degree bevels on top of the rail.

Disc Cutting 0,8mm Carbide Silicium

Gerald D · #26 Fri 10 October 2008, 04:29

Hi Yuri, the disk looks okay. (use as per second pic). Interesting that you find such a thin disk with a "cup" (hollow) in the center. I only know thin disks that are completely flat.

YRD · #27 Fri 10 October 2008, 07:18

Hi Gerald,

I have the option completely smooth and 0.8 / 1.0 or 1.6 mm (thickness). Which to choose?

Kobus you cut the 28 mm with "skate" supported by only 4 screws? Nothing else? He ran the skate supported only by hands?

What is the best option for a man cut the 28mm?
1 - Cut as Kobus (sliding skate cut)
2 - Cut Fixed (skate fixed on the table)

Kobus_Joubert · #28 Fri 10 October 2008, 07:55

Yuri, I clamped the rail on my table saw top. Then only supported by hands cut a short piece. Then move rail and cut the next piece until finished.

I must say I have never seen thin cutting disks with a CUP in the middle, that is why I thought they were grinding disks.

Gerald D · #29 Fri 10 October 2008, 09:11

Yuri, I like the method of Kobus (and Hennie) . . . . Fix the rail down to a horizontal table, and then use sliding skate. First take light cuts to make a shallow groove and then use more force to go deeper. Move the skate forwards and backwards a lot, so that you never cut hot steel - always cut cold steel.

"I have the option completely smooth and 0.8 / 1.0 or 1.6 mm (thickness). Which to choose?"

I do not understand the "completely smooth" part? In general, the thinner 0.8 should be the best, but start with very light cuts to make the first groove.

YRD · #30 Fri 10 October 2008, 10:21

I have flat disc or CUP at 0,8 or 1,0 or 1,6mm.

Better flat disk or CUP disk ?
