what material are you making it from?

I'm a little worries about the sides of your x-axis. it looks quit high but small (it isn't stiff enough I think)

forget the question, assumed some things wrong

Mister H
02-19-2007, 11:51 AM
still got a question, what kind of linear bearing do you intend to use? I don't really see them

GERY
02-19-2007, 01:22 PM
hi mister h,
My english is really limited... It's a little machine x 350 y 250 z 100 mm..in aluminium...The bearing systeme is a home made "glissieres" (i dont know this word in english may be "slead"...???)..

ma francais est limité aussie ;) je croix une glissiere est "sliding bearing"

your design looks ok, but why don't you use a standard (proven) design?

jmytyk
02-19-2007, 08:10 PM
i think it's great that you arent using a standard design. keep going, you are going to run into problems but thats really the best way to learn.

i found that taking parts and pieces from other designs out there- you can build your machine how you think it would work the best.

HI all,
Thank jmitik, i want make all parts of my machine in leaning....

i start my project....here my 4 axis controler (cnc4bu (techlf.com)..
I made a cooler (heat sink???) and i use the air flow of my alimantation
for cool it....a little pdf of details...sorry in french...

Now i start the building.....here drilling with a little table xy...it's the X rail..

Gery,

It looks like you a planning to use brass or bronze gibs on aluminum rails. Is that what I am seeing?

Looks great. :) I just have one question:
Why is your X stepper inside instead of outside your end beam? Would you slightly increase working area by flipping it to the outside?

GERY
04-17-2007, 08:02 AM
hi all,
Yes alan it's that
Yes thkoutsidthebox it's a good solution...
Just a little video....of sliding

acondit
04-17-2007, 12:21 PM
Gery,

Aren't you worried about wear on the aluminum?

Alan

GERY
04-17-2007, 01:32 PM
hi alan,

no, because the brass has one excelent friction coefficient...and the weight
total on this axe is 1.3 kg

acondit
04-17-2007, 07:43 PM
Gery,

Good luck, I hope it works out for you. It looks nice.

Brunow
04-25-2007, 03:02 AM
Nice. It looks bigger on the pictures .
I do have my doubts about the bronze rails. But if it works for what you are planning to do with it. GO FOR IT :-)

GERY
04-26-2007, 01:14 AM

Looking very good. I may borrow a few of your ideas when I build mine. Looking forward to the rest of your build and completion.

Keep up the fine work.

GERY
05-31-2007, 01:16 PM
Thank guys for your support...
The next step is the bearing supports....made in pu resin...
Now i work on the model (in wood) for mold it in silicon and cast the pieces in Pu resin...few picts next week..

05-31-2007, 09:52 PM
gery ...

i like your machine ,cant wait to see the whole thing...you dont see many "sliding surface" guide ways i like the idea..was thinking about a steel machine built the same "way":) am interested to see how the alum. and brass guide way will work...i love the look !!...keep up the good work!!

GERY

hey gery
this may be a repeat..i just sent a reply..but had a problem sending.it...any way i was wondering about your mold are you gonna home metal cast some bearing blocks in those molds?? and by rtv do you mean rtv silicone? im just curious about the mold you made..

GERY
06-12-2007, 08:21 AM
Hi xacex,
Yes it's rtv silicone....some picts tomorow of the casted pieces..

GERY
06-13-2007, 11:41 AM
Hi all,
The pieces are casted.....and the first is positionned....

JerryFlyGuy
06-13-2007, 12:12 PM
Very interesting, what kind of Pu Resin did you use? Name or brand? Is it flexible like a nylon or UHMW would be?

GERY
06-13-2007, 01:02 PM
hi jerryflyguy,

It' pu resine 78a 78b type and rtv 181 type silicone..
You can find it here

Hi all and thank jerry...
The same operation for the power joint ( Cardans ?)
Made with a little piece of candle wax...

Brunow
06-14-2007, 08:29 AM
Candle wax... Where do you get the idea's? :)

Nice work with the molds!

Arthur Clampitt
06-14-2007, 08:25 PM
An interesting and low cost way of approaching the problem , Following the build with fascination , very interested to see how the result turns out

Do you think it will cut 5mm steel plate :-)

.xXACEXx.
06-14-2007, 09:43 PM
hmmm... something else..ive never seen before...pretty good idea's ya got there! if that stuff is pretty strong or could be reinforced with something...a person could make about any thing out of that pu resin stuff

GERY
06-15-2007, 10:56 AM
hi all..thank for comments...

Power joint are finish....next shot in one week, yes i'am in hollydays...

The little video

Brunow
08-06-2007, 01:50 PM
:) looks like it run's well!

Did you run some milling tests?
And what software are you planning to use?

Ow if i may ask. What's the current budget you have spend on it?

GERY
08-07-2007, 08:25 AM
Hi brunow

Yes i did run some test in september ... a wood wing's parts of an old german glider at 1/4 scale....one "rhoensperber" rhoensperber.de.

I use now rhino for modeling, Deskproto for toolpaths..and isa4d for milling (it's free with my 4 axis controler....techlf.com)

For my budget, 700 euros for my controler and four motor nema 23
95 euros for sprindel (proxxon)
200 euros for material (alu.etc...)

Hi all,

The first test of accuracy.......with this little files ...FORM.iso

wich you can download here..

http://rapidshare.com/files/50525470/FORM.ISO.html

With it,You can test your cnc accuracy..

Just a little piece of avia multiply of 4mm..

Feed rate 50 mm/minute, speed 5000t/minute pass 2mm tool 1mm diam

Kool accuracy for my plane building...

08-30-2007, 09:47 PM
im sorry i was gonna ask this earlier...you mention ...."Just a little piece of avia multiply of 4mm.." ...is that like plywood,or more like card board,just wondering... :)

GERY
09-19-2007, 07:30 AM
Hi all,
Soory xxacex...i'm late, i was in hollyday last tree weeks...
Avia ply.....it's a plywood made specially for aircraft industrie with a wood of birsh...it's a really light weigt and very strong wood...

.xXACEXx.
09-23-2007, 03:29 AM
cool ....i figured it was ply-wood ,aircraft grade is pretty strong plywood...at least model airplane ply wod any way...from what i've seen,...hows the machine running ....smooth?,little wear on linear guides?,no binding?....pretty cool looking machine ya got there :)

LeeWay
09-23-2007, 08:19 AM
Nice job on the build. I too was curious how the brass gibs would perform. They seem to work well. I like to see guys build original machines using non standard designs.
I know they do have bronze material that is impregnated with oil. I think it's called oilite or something. I use these bushings in my product, but only because they are also the cheapest I can get in the size I need. I don't need the oil in there, but it doesn't hurt anything.
When I cut them on a band saw, oil just pools on the cut. Neat stuff. If you every have trouble with the brass, you may look into this stuff.
Show us some parts when you get them done.

.xXACEXx.
09-24-2007, 10:12 PM
oil lite bronze is some pretty funny stuff...when you machine it it smokes to no end...unless ya use coolant..and when you grip it in a lathe just closing the chuck makes the oil come out of it...and and just the heat from holding it in your hands will cause the oil to come out too..pretty neat stuff that oil lite is..:)

GERY
09-25-2007, 04:01 AM
hi all, and thank for support...

Yes the machine running nicely....

Brass skates is a good way....

The first pieces this week on your site...

Hi all,
Thank harrin...
I don't like noise...so i work on a "Anti noise box".....all mechanik part on "silent block" (littles pieces of caoutchouc)......no vibrations transmitted.

Hi mr chip

I just tested the download..it's work...
Just choice "free"....and you type the number wich you see in the windows...

Thanks for the Gcode.

I signed up and still do not see the download option, however I was able to upload two files.
Do you have to purchasing a premium account to download?

Thanks

really cool router gery ,nice video,i went back and reread some of you post but,i didnt see what program you use to drive this machine im particularly interested in the 3d stuff ,as i could probably come up with some 2d code .but, you are running in 3d .or atleast "x" and "z" and thats something i cant even imagine trying to code out im my head...so i figure you have some cool modelling software (rhino??,autocad??)and something to create g-code (mastercam??) so i ws wondering what you use to "draw" and g-code something like that plane in your video ive been machineing for many years ,cnc lathes mostly..so i am clueless to 3d milling or "router-ing" thanks!
