You are not kidding... sweet!

With something that nice, was it cheaper than purchasing the geared steppers from OM?

[Gerald D]

It is beeeeyooootiiiiiifuuuul!

Do you have the N.C.I.A.M.T.S.F. engraved into the plate?

[grandpi]

Impressed by the parts quality, nice job. ... i'm waiting for your impression (quality of cut improvement) after first trials. Maybe, could we hope a PDF plan set to try the same ...

Bye,

Pierre.

[J.R. Hatcher]

Thanks everyone. We designed it so it works with the existing motor mounts therefore it works on all axis without any modifications. The picture is for Sean, it's a vertical mill attachment for my atlas lathe.

JR and Marc,

Very nice. Look forward to hearing how it works.

Now we know who to contact for parts.

[Kobus_Joubert]

Nice to have all the tools AND knowledge. Nice job.

[Gerald D]

Okay JR, what title do you want for this thread? .......

"Done! Setting up dust foot & table top"

........seems to be in the distant past already.

PS. like the inclinometer indexer!

[Robert M]

You must be proud of this result. What gears specs did you guys use ?
Congratulation to you & Marc, verrryyy nice work.

[smreish]

jr. I thought you might have that attachment. I knew you had a lathe, but never heard mention of the mill. Bravo. By the way, I have the same wixey incline gauge, I couldn't live without now that I own it.

JR,
Great photos, cannot wait to hear how the gearing improves your cutting. Keep us informed and some more photos.

[Doug_Ford]

JR and Marc,

Y'all are amazing. That is some truly beautiful work.

[DMS]

Truly Professional work. Even OM guys will envy

J.R. and Marc,

Very impressive design and fabrication work.

[Marc Shlaes]

Thanks guys! I can tell you this...

When I look at the work and 15 odd cuts in MDF to get it how we like it, I am more and more impressed with Gerald getting this whole machine designed.

Regarding the question of cheaper than buying geared motors... Hmmm. Probably not on a one-off basis. But, JR had the motors and wanted to use them.

In the end, this might work out better because of the ability to adjust resolution to suit one's needs by varying the ratios possible in the belt drive.

I am certainly no expert and until they have been cutting for a while, it is too soon to tell. Even though we designed it, Gerald is much more qualified to comment.

It still is simply toooo cool to draw something and then see the Mechmate cut it EXACTLY. I am sure that I will eventually get used to it but right now it is very exciting.

Thanks again Gerald!

Fabulous work folks! culmination of creativity engineering and beauty combined !

Robert,

The drive pulley is 15 tooth and the driven pulley is 45. They came from SDP-SI as did the belts. The belt width is .375 and the pitch of the components is .200.

If you need anything else, just ask.

[domino11]

Marc or JR,
I am interested as well as Gerald, as to the engraving on the motor plate in the picture that Gerald has posted. What is that?

[javeria]

Marc,
Can you put in the drawing for these with bearing mounts and the bearings you used on these. Think G can make this a standard option for people who want to go on with a reduction belt drive. also the SDP-SI part numbers.

Or is it very soon to ask for?

I love the enthusiasm here. (Gerald, I now feel a tiny, tiny bit of what motivates you.) However, before we publish anything, let us try it out first. It might look really nice and yet not perform at all. Hopefully not!

May the force be with you !!
Aaa, It’s humor not for all but with a smile intended…

Marc, thanks a lot for these infos. Will help others & me a lot. I to have the firm intension making my own reductions, looks better, fun & more versatile than those enclosed expensive gearboxes!
You & JR, Fabio & others have convince me it’s the way to go !
Great forum & place to be. Looking forward to share at my turn some of my future built !

I may take you up on that latter, never purchase for this need/purpose, any parts No. handy so I can compare ? Seen so many choices & option on the SDP/SI online store !!!

Merci, Robert

[Marc Shlaes]

Oh... By the way. The engraving says www.cnc-nc.com. We built the website in preparation of actually finding ways to make money with this CNC thing. As we get further (and test the belt drives) we might put completed transmissions for sale there for those that don't feel up to cutting 1/2" aluminum on their machines.

We will post the DXFs for personal use for all you adventurous folk as soon as we know they are right.

Marc and J.R.

[Gerald D]

May cnc-nc grow from strength to strength!

[Marc Shlaes]

Thanks Gerald.

And for all those who have, in the past, asked about cutting aluminum. Even a direct drive machine will do it if you are patient!. As soon as the transmissions are installed, we will cut a second set and surely report on the difference.

Oh and for David. I obviously like the collaboration thing. We each bring different strengths to the party. That is what makes this so great! I couldn't do any of this without you guys and I am sincerely grateful. I love pictures.

[Greg J]

Marc and J.R.,

Best of luck with CNC-NC !! I'm sure I'll be using your services in the future. Don't have to worry about the quality with that group.

[Gerald D]

Want to wish JR a Happy Birthday! one week early, because I won't be here next week. One year ago you started this thread with:

Thanks in advance for all the help. I see it passed out everyday on this forum, thanks. I promise to update often with pictures. J.R.

Those serious challenges came from an unexpected quarter, but you pulled through and lived up to your promises. Well done JR, and thank you very much for being an inspiration to the rest of us.

[cobra427mnsi]

I'll say an amen to that and a happy birthday

Paul

[domino11]

Happy Birthday JR.
I hope all our machines turn out half as nice as yours!

[J.R. Hatcher]

The transmissions work great it makes all the difference in the world, in speed and the way it cuts. Here they are on the MechMate.

[smreish]

JR,
Stunning achievement. It would appear that you used the MM to machine the aluminum gearbox plates. Just another point to prove to all the others that aluminum is just fine on the MM. I have had no problems cutting 3/8" plate with the correct bits and feed rates.

You will notice the biggest changes in cut quality on plastic.

Keep up the great work....
Sean
