Carved coat rack #41 Soddy Daisy, Tn

[Castone]

4715
Here is a butterfly that I made for a coaster. It is about 3" in Dia. It has not been sanded. It was ran on a Mechmate machine.

[Jayson]

Nice work Leo.

Time to try some 3D myself I think...

Jayson.

Leo,

Very nice. Now, try recessing the butterfly so that it is below the surface of the inner surface. I like the way you rounded the outer ring. If you change the stepover, you might be able to eleminate the lines that your 1/8 ball nose left on the inside of the wings. I had that problem when I did some grapes in corian.

Your machine is square. It is great when you don't have to sand.

Lets see more pictures.

[Gerald D]

Havn't done it myself, but apparently it helps a lot to get the tooling marks going in the grain direction - helps with the sanding.

[smreish]

...a little workshop note I have had success with in the past.
Before you make your final cutting pass, assuming you have a roughing tool and final finish tool, I do the following:

-rough the part with the 1st tool
-spray with a very "light" mist/layer of water to raise the grain of the wood.
-wait about 20 minutes
-parallel finish cut with at least 60% step over

Depending on your humidity, raising the grain helps the fibers to be cut stand up. Thus, when you cut the final pass, the wood will sometimes "shrink" a little bit and give a little tighter grain that needs "less" sanding.

Good luck.

* this worked well with Conifers (like redwood, cedar, soft pine) Maple and Ash not so much :)

4724 This one was cut from pine using a .042" end mill

[Gerald D]

Leo, now we have to see pictures of your MechMate :)

[Castone]

Hi Gerald, It is not quiet decent yet. I had built a very small machine just to test out everything. your plans have worked great. But I will get some pictures up as soon as I get it back in shape and increase the table size some.

[Castone]

Here is the STL I made to cut it from.4725

[Gerald D]

Okay, a new rule for this Showroom section: First show the machine, then show the work.

Don't be shy Leo!

[Castone]

Copied from another thread:

As promised here are a few pictures of the belt drives mounted. I have a few more mold patterns to finish cutting , then I will put up a few pics of different materials such as abs , aluminum and wood. And thanks to JR for getting me started on these belt drives. May also make some ABS vacume formed belt gaurds for them if I can find the time. Thanks

[J.R. Hatcher]

Everything looks great Leo. I know you are proud.:)

[Gerald D]

Leo, looks like you have earned serial #41. Great job!

[Gerald D]

Oops, I closed this thread by mistake - sorry guys, you can flood Leo with comments now!

[jhiggins7]

Leo,

Congratulations on the MechMate and Serial #41.

I've updated the Builder's Log here (http://spreadsheets.google.com/ccc?key=0AttqjIPMBEXKcExveGc4d3U0V25zQmMyX1U1eUVhU Xc&hl=en).

Please provide a little more information for the Builder's Log. What are the dimensions of your MechMate? Also, about when did you begin the build?

Please check the entry and let me know any changes you would like.

Love the tranny's.:)

[Gerald D]

Before I knew what a "tranny" was, I googled it, and the results were not pretty (http://images.google.co.za/images?hl=en&safe=active&rlz=1T4IRFA_enZA279ZA280&um=1&q=tranny&sa=N&start=0&ndsp=20)! :D

*slaps side of head* transmission! tranny = transmission! That's what we know as a "gearbox".....English cars have gearboxes, American cars have "transmissions" or tranny's

[Castone]

Wish i had not looked at that ! That link should have a warning label on it.

[myozman]

Congrats Leo,

Don't worry what it looks like. The dustier, the better. I used to Vac mine off every use, but now just when someone new wants to see it. I try to keep the rails and rollers clean.

Tighten up your stepover and the detail will be improved.

Can't wait to get your "tranny" plates.

Mike

[Castone]

Hi Mike and thanks , should have you some this week. I leave my step a little on the big side as I only use the wood as a pattern for most things I make. Then I pull a mold from it to make a concrete bench molds from abs. Which mainly I just sell the molds , but as you can see I do pour some of them.
Just click on the link Gerald put up and you will see why I said , I should not have looked.

[jhiggins7]

Leo,

Your work is really outstanding, thanks for sharing.:)

I added the information you sent me by PM to the Builder's Log here (http://spreadsheets.google.com/ccc?key=0AttqjIPMBEXKcExveGc4d3U0V25zQmMyX1U1eUVhU Xc&hl=en). Thanks for the PM response.

[Alan_c]

Leo

Nice work, would you mind giving a bit more detail how you go from CNC cut pattern to the final mould (if its not a trade secret).

ps I like your trannys better than Geralds :eek:

[Castone]

Alan , I sent you a PM

[lunaj76]

Very nice work!

[Claudiu]

Hey Leo,

Congrats on #41.:)

Making a new coat rack for myself. It is 40" long about 10.50" wide, ran about 3 hours . Need to do a little sanding and staining add some hooks and she will be ready to hang on the wall.

[Kobus_Joubert]

Nice Leo, hope you made little drilling marks with your MechMate where you will be putting in hooks for the coats. I do this then I know the things are spaced evenly.
Show us a picture when it is finished.

[Castone]

Here you go Kobus, My camera does not work as well as yours. But here are a couple pics. The screws to mount this to the wall where to be under the hooks so they would not show. But when I started to hang it there where no studs in the wall ,that were spaced like I needed to let me center the thing where I wanted to put it. So I asked my wife if she would ever want to move it later on and she said no, so off I went to get the double sided tape I had left over from my build . I know I will regret this someday but not today HA HA !!

[swatkins]

Next time you run into the problem of studs not being in the correct place try one of these..... http://www.easyanchors.com/ They work really well!

[Kobus_Joubert]

I like I like it very much. Hope the double sided tape will hold the load if all 8 hooks are full of coats. Otherwise you might have a new ventilation / inspection hole in that drywall someday

[sailfl]

Leonard,

Your coat rack looks great. Thanks for sharing the final piece.

[jessyjames]

Leonard, looks great also. What I would do if I were you is to buy some drywall anchors and screw them into the wall then use screws to attach the coat rack to the wall. If you have plaster they have anchors for that purpose.

Good job :)

[javeria]

Leo - what stepover do you use and what is the ball nose bit size

[Castone]

Thanks to all . Irfan , I ran a .062" Dia 15 deg cutter at .012" step over. I ran it all in one pass with an edge prep on the boarders. Cut speed 200 IPM

[domino11]

Leo,
Very Impressive. I love the stain colour. :)

[Rad Racer]

Nice work Leo, love the design.

What did you use for design software.....ArtCam?

[Castone]

Hi Wayne , I bought the image of the goose. Just drew the outlines in 2D , the basket weave is just a texture and programed it in mastercam. Thanks , Leo

[Castone]

Here is another one with some live action 12" x 36" .

[javeria]

I like the Mastercam toolpath generation, donno why the art cam wants to do same speed everywhere - I like the way your machine slows down when encountering a 3d and accelerated on a flat, btw what post processor on mastercam do you use.

[Castone]

Irfan I can send you the post if you would like a copy. PM me and send me your email address

[javeria]

Nope Leo - I have solid cam with me and wanted to know what post matches for mach, I will try the fanuc one.

[Castone]

My post is just a fanuc with a few mods made to it. I dont think it is all in the software I use. I have my accel set very high compared to most people which gives me some of this. The machine can only reach my plunge and feed rate when it gets to a straight cut. I will use a plunge rate of 100 or 200 IPM and a feed rate of 200 to 400 IPM most of the time as I try to program so that I never plunge into the material. That is one of the reason I make a cut around the part first.And keep the tool down as much as possible. I also try to reduce any long rapid moves if I cut anything over 600 IPM when the model is large enough to do so, of coarse I mainly cut 3D stuff. I would be glad to share my motor settings with you, if you would like to try them.

[Castone]

Drew up some new 3D designs , just practicing. It came out pretty good. Need to go back and make it a little deeper in a few places. I have not cut the other one yet. Cut time 15 Min. Material MDF.

[sailfl]

Leonard,

Looks great.

[KenC]

Nice!
