Wayne,

Nice idea and nice work. You have inspired me.

domino11 · #**153** Mon 07 September 2009, 18:39

Very Nice Wayne,
You can never have enough storage.

jehayes · #**154** Wed 09 September 2009, 20:34

Nice job. Thanks for sharing this idea. How did you attach it to the cross braces?

Rad Racer · #**155** Wed 09 September 2009, 22:11

Thanks, glad you like it.

I used brackets made from 1" angle iron....simple but effective. I will take a photo tomorrow.

It is a nice cabinet, but it occupies space that we often use for G-clamps to hold workpieces down onto the table.

First thought that you could set the cabinet further back so that the clamps can work in front of it, but then realised that the long end of the clamp hangs down and would obstruct the drawers.

Still is a nice cabinet though, just needs a good location . . . .

Haven't posted for awhile, so I thought I would share some of my latest projects.

First is the finished tooling cabinet. (never supplied final photo as promised)

Next is a couple photo carvings. These are for the end of the year banquet, held by my RC flying club. Shown are the orignal photos and the wood carving. One of the photos is flipped, so it does not look exactly like the carving.

Nice work and nice of you taking time to share these
Amicalement, Robert

Taking the lead from Greolt(Greg), I finished my 4th axis and starting carving Lithophanes. I saw what greg did and had too try it for myself.

I used Photovcrave and CNCWrapper just as Greg did with his carvings. The last photo is not focused, but gives you an idea of the detail. It is amazing to see these things with back lighting.

martin77pl · #**160** Sat 14 November 2009, 02:42

Wow, beautiful work. What material are you using? Is it white pipe made of plastic.

Rad Racer · #**161** Sat 14 November 2009, 07:24

Yes, it is plastic (PVC). PVC pipe is very common here in the US, it's used primarly for plumbing.

Rad Racer · #**162** Sat 14 November 2009, 09:38

Here's a YouTube link......it shows the 4th axis in action.

Wayne - can you tell us more about your mach settings on this one - probably detailed snapshots would help. - and did you set any backlash settings? - what is the reduction you are running

I am planning for a 1:16 reduction using double timing belt setup.

btw - very nice work

Hi Irfan,

The settings for Mach3 are pretty straight forward.....I have a few screen shots that should help.

Be sure to slave your "X" axis on the MechMate to either the "B" axis or the "C" axis. You need to use the "A" axis for the rotory table.

Setup your ports and pins to support the "A" axis. (see ports and pins photo)

Make sure that both your "A" and "B" axis are enabled. This is done on the "Settings" tab. (see axis enable photo)

Setup the "toolpath" to enable Mach3 to display your rotory work. (see toolpath photo)

My rotory axis is built from a Sherline rotory table, I just mount a stepper motor. The Sherline table has a gear ration of 72:1 (5deg/rev.)

Hope this helps,
Wayne

Castone · #**165** Sat 14 November 2009, 20:55

That looks nice, might have to try that.

Rad Racer · #**166** Sat 14 November 2009, 21:28

Thanks, glad you like them.

I made some more today, they will be the table center pieces at our end of the year banquet.

The details with backlighting is amazing....take a look at lithophane of the guy holding the plane(me

)

Greolt · #**167** Sun 15 November 2009, 00:08

They look great Wayne. The detail certainly comes through.

What sort of tool and stepover are you using?

And what is the range of thickness of material left?

Greg

Claudiu · #**168** Sun 15 November 2009, 02:59

Wayne,

these look absolutely awesome.
I`m impressed of the details which are possible with this technique, especially the guy holding a plane!
These are the things which push me more going back to work...

How thick is the PVC tube (wall thickness )? I see you have machined it in some places up to 2,5 mm - 3 mm ? Is that corect?

Great work.

Rad Racer · #**169** Sun 15 November 2009, 07:29

Greolt,

For the rough cut I am using a Onsrud 1/8" tapered ballnose (77-104). The rough cut is up to .180" deep (in areas with very light features), with a 50% stepover @ 50ipm.

The finish cut is with a 1/16", 2 flute, ballnose cutter. The finish path takes an additional .02" material. The stepover is 15% @ 40ipm.

The total cut depth of both passes is .200", the PVC is ~.240 thick....so the lightest areas have a material thickness of about .04".

The cut time is about 2hrs......15min. for the roughing and 1hr 45min for the finish cut.

Wayne

Rad Racer · #**170** Sun 15 November 2009, 07:38

Claus,

I appreciate the kind comments, thanks. The PVC is ~.240" thick (~6mm), some areas are as thin as .04" or about 1mm.

The MechMate is a great design! For me, these fine details sure highlight this machines capablility to hold tight tolerences.

Wayne

Kobus_Joubert · #**171** Sun 15 November 2009, 09:58

I like I like.. Well done and keep them comming, I like to see this kind of stuff.

jehayes · #**172** Sun 15 November 2009, 11:04

Wayne, thanks for sharing these, they are an inspiration to those of us who are following along in your footsteps.

Rad Racer · #**173** Sun 15 November 2009, 21:35

Thanks Joe. Greolt gets the credit on this one, his YouTube video got me started.

Robert M · #**174** Mon 16 November 2009, 04:45

Defiantly nice. An inspiration to keep in mind when my indexer will be ….soon !
Good work and thanks for sharing those, Robert

Been awhile since my last post, so I though I would provide a quick update.

Been using my Mechmate like crazy, logged nearly 100 hours of cut time in the weeks leading up to Christmas. Most of this time was spent cutting lithophanes. They have turned out to be very popular, seems that everyone that see one, wants one. We have sold about 40 of them....most for Christmas gifts. If the orders keep up....the Mechmate will have paid for itself in no time

In an attempt to drum up some more business, I created a website. Although not quick....webpage creation was certainly easier than I first expected. The page still needs some tweaking, but am pretty pleased for a first attempt.

If you got a minute, check it out, let me know what you think. www.radcut.com

I am currently working on a new RC airplane. It is a scaled down version of an RC airplane build in the 70's. Of coarse, all the parts will be cut with the MechMate.....he's my buddy

domino11 · #**176** Wed 06 January 2010, 20:25

Wayne,
The website looks good, I did have some overlapping text issues with firefox and my font settings though. I really like those lithophanes.

Gerald D · #**177** Wed 06 January 2010, 22:48

It all looks good Wayne

lumberjack_jeff · #**178** Wed 06 January 2010, 22:52

The site looks great on Google Chrome, Wayne. Very nice.

Sergio-k · #**179** Wed 06 January 2010, 23:23

Wayne you 've done a fantastic job !!!
congratulations, you have inspired a lot of us in this forum.

Just another example that multithousand cnc machines
doesn't make you a better crafter.
Imagination, creativity and a Mechmate could do the job.

Claudiu · #**180** Thu 07 January 2010, 01:04

Great Site, great Work!
