914World.com _ 914World Garage _ Got a new toy. tool.
Posted by: RJMII Jan 20 2010, 09:29 PM
For Christmas I scored a Jet Hobby Mill to go with all of my stepper motors and CAD-CAM software and 3-d scanner.
I still need to get the correct collet and end mills; but I'm quite excited to get started machining some parts.
Does anyone have a 914 emblem I can borrow? Someone was wanting a 914-8 machined, and I need a 914 to scan and model to get to cutting out some aluminum parts.
Also; does anyone have an R/C 914 setup? I'm planning on machining the Fuchs wheels out of aluminum and need someone to help me out with getting the offset and diameter just right.
I'm also thinking of machining a 914-World emblem for the backs of our cars out of aluminum. If I do go for that, I'll snail one off to Eric first, get his opinion and stamp of approval.
I've been studying online all of this stuff on CNC and machining and am quite excited to actually get going with some 'on hands' stuff!
Any other suggestions, for things to carve out of some aluminum?

I will send you these wheels after the Build Off. I'm going to bring it to the Build Off for AX compitition. These are the closest I could find to Fuch wheels.
Oh! and I have another project for you. Brass 918-S script for my tail light panel.
And I need an aluminum plaque made for the Shealey.

What collets do you need? R-8 MT, ER. I have 30 Cat50 holders in my dining room right now. I may have what you need. ( I know its not a CT machine, and the 50 taper is bigger than the whole head on that!) And I MAY have some end mills left in my old machinist box. Let me know.

ooh oooh... awesome; thank you for all of the help, guys!
Rick, same font as normal 914 emblems? And thanks for the wheel set loan! Are they a good offset? We'll have much closer than that by the time I get done playing. 
Mr. underthetire; This mill takes MT2 style stuff. It's definitely small!
I'd like a few different shapes to get started with on the end mills. A ball headed one or two, a corner rounder or two, and then square nosed. I can adapt spindle speed to number of flutes and materials.
I think I need hold down clamps as well. I haven't had a chance to check it all out yet. it showed up an hour before I went into surgery, and my dad unpacked it and set it up in his shop for me. He sent me that particular pic as well. I haven't even plugged it in yet. My excitement is growing. thanks again!

thanks again!very sweet dude I was thinking of getting a mill also ,just because I'm always making something more like things that I can use when I'm shooting.(camera) stuff But I never used one and don't know what to buy for (tools) or bits?

Posted by: BKLA Jan 21 2010, 10:35 AM
I have an original 914 & 2.0 rear script off a '74 that I could let you borrow, in addition to a set of unmounted R/C wheels exactly like the ones Rick suggested. (as long as I'm second in line for R/C fuchs wheels - assuming you are first :wink:) I'll even ship them to you with a return box!
edit: email me and I can ship them out this weekend...
If you are going to CAD/CAM it how about having them scanned in 3D? I might know someone local with a 3D scanner?
Posted by: kwales Jan 21 2010, 10:45 AM
Good luck with the scan.
So far I've tried it three times, and have been underwhemed.
Once with a point cloud on silicone gastric bands,
Once with white light on a really tiny steel part,
Once with x-rays on the tiny steel part.
It's sorta close and straight lines aren't always straight so you have to redraw/rebuild in 3-D CAD.
With the gastric bands I ended up using a grid pattern and a caliper, and cuting the parts in pieces to get the cross sections. That finally get it right.

I think it was 3D Scanning.
It was a German system and they even sent our part to Germany and the system designers couldn't do it either.

I have an original Next Engine Scanner and a full size 16x7 Fuchs (a whole set of them, actually...) that I can scan.
For the scripts; the plan is to take a picture over head, straight on, and then trace around them with the vector pen tool, then export to a file that bobcad can import.
They are just 2D with rounded over edges... (and the area where the digits are held together is just another lower level of machining)

Can you educatem me a little on the necessities of rigidity with the carbide bits? HSS vs carbide? Could I not still control spindle speed and plunge speed if the machine isn't stout enough to handle fast?
hmm.. yes. ball mill, chamfer tool, and center cut. =o) I think using those terms I might be able to find more bits for purchase from vendors as well. Thank you again!
Posted by: rick 918-S Jan 21 2010, 08:54 PM
OK, sounds like you have a set of wheels coming. That's cool.
Yes, 918-S same font as the Porsche script. I would send you mine off my tail panel except I sent to another guy that was going to make me one from composite and cover it in gold leaf about 5 years ago... So, that's why I don't have a script on my tail panel.
PM me your address, I will send you a piece of brass for the 914 and a piece of aluminum with the info for the script for the Shealey.

Carbide is the worst thing in the world if the machine is not rigid enough. They will chip and break where HSS is more flexible and won't. Speed does not matter so much, although carbide should be run much faster than HSS. It's all in the spindle and slide manufacturing. Any lateral movement will cause you nothing but headaches with carbide. We see this a lot even on the large CNC's, a cheap Hurco for example will not cut anywhere near like a Mori Seiki, and the tool life is double on a Mori. We are talking machines in the 75K to 250K range though. Not exactly garage stuff. Although I do know where a good used Mori is for 12K, I just don't have enough garage !

Yup.
If no one is making them anymore, I'm planning on giving it a shot. I haven't seen anyone making them, or answering the WTB ads in the Classifieds, so I'm going with the idea that I'm not stepping on anyones toes. If that's not the case, then please, let me know.

RJMII, I would be interested in seeing more pictures of your stepper motors hooked up to your mill. Also, what CAD/CAM package are you using?
There are a few ways to check your spindle to see if you are rigid enough to use carbide. Do you have a dial indicator and stand? If you do you can set the magnetic base on the table. Set the dial up to your tool installed in a collet. Spin the spindle by hand see how far out you are. Also push the spindle around with your hand and see if there is any sideway movement further up in the head. If your spindle is not "true" than precision machining can not be achieved very easily, and carbide will tend to chip or break on you.
Never put anything in a drill chuck except drills. No endmills, fly cutters, etc. Use collets for those. Speed and feed is very important to learn expecially running it CNC. The machine doesn't care if you are running or feeding too fast. It'll either break the tool or spit the part out at you. Which brings me to another point. Always secure your part to machine. Nothing will ruin your day or your life like having a chunk of steel fly out at you.
I don't know how much you know about machining, but I thought I'd throw these points out. Have fun with your mill. If you need help I will try my best to advise.
Posted by: Smitty911 Jan 23 2010, 07:23 PM
Well I've gone down the path you are traveling, it's not cheap by anyone standards.
I have the Harbor Frieght with Steppers, Mach 6 controlles, Gecko Stepper Controllers, 3 axis CNC. I'm in about $5,000 for my set up. I also have retrofitted a kit with ball Screws and zero backlash. Thanks to the extra $1,000 I spent. Add Alibre CAD/CAM for around $850. Some other small software issues and than you start hitting the money vein.
In retrospec I should have left mine Manual as I could make parts faster. But I make mostly one off fixtures for testing Cables.

Brodie; Thank you for the info! That is very much appreciated.
Right now it has a drill chuck setup. Tonight my uncle, my dad, my wife and I were playing around with a dremel bit and some pine. We made grooves. =o) The machine came with clamps and a quick vise, and we did indeed have the piece of wood secured to the mill.
It was quite fun! The machine seems quite sturdy for its size, and I'm looking forward to figuring out which parts I need to order next to set it up for milling.
The steppers are in storage still, and I was looking over the machine to see how to incorporate them into the whole equation.
I have bobCAD; I picked it up for $325 because I'm a hobby user and caught their latest ploy to sell software. Hopefully the software is as good as the guy that was selling it.

Ok, was able to take a look to see what I had, most everything I have left is 1/2 " or bigger. Too big for that collet set up. My "special tooling guy" is gonna get me a couple 1/4" stuff. He can be a little slow on the free demo tooling, but i'll do what i can.

Hi, that is one cute mill. I have never seen one so small. Here is a picture of the CNC mill I use at work.
If you do make some of those wheels I would be interested in a set, would they be for the correct size to work with the M-04 body?
One of my mills....its an Okuma

Cool, I used to work for Okuma. We just bought 4 new Mori-Seiki mills. We have a bunch of newer Okuma lathes as well. Two of the Mori's we just bought are 1 micron accuracy machines over the entire travel. The other 2 are shop floor spec, the normal .0002 stuff over 40".
Can't figure out what model that is. Sure it's not an Okuma-Howa?
Posted by: underthetire Jan 23 2010, 11:39 PM
Oh, and if you need any nice 50 taper tooling, let me know. I got a bunch of new old stock sitting in my dining room...
OOPS, never mind. I see your in Japan. I went there for training for Mori-Seiki back in 97. I was in Nagoya, Iga, and Nara.

Actually it looks big but is small compared to some of the others we have at work, I use this one the most, mostly mill and machine steel parts used for big progressive dies. I forgot the model name I think something like 50cv or something like that, its actually quite old and we bought it used around 10 years ago or so for 35,000 Dollars roughly. We have 5 other high end Okuma's that are for very detailed work and cost as much as a nice home. The Okuma machines are very easy to use with their OSP systems, none of that Fanuc stuff.

If you are going to make emblems, I would like to get a couple made.
One for my big motor... I need a 4.0 emblem for the back.
The other is for my taildragger. I want a 912-6 emblem.
I was going to buy a 914-6 emblem and a 2.0 emblem and do surgery, but this sounds like it will be much better.
Posted by: Brodie Jan 24 2010, 08:39 AM
RJMII,
Bobcad is a fairly decent program. It'll serve you well. There are a few weird thing that you scratch your head as to why they did that. If you need help let me know. I've messed with bobcad V21, V22, and V23. Just let me know what version you have. It will do 2D work really good, and 3D work can be a challenge. They will call you a lot with upgrades. Hope you like telemarketing 
Use some scraps of wood like you were to get use to it. Tools last a lot longer, material is cheaper, and if you accidently rapid into the wood the chance of breaking a tool is less.
Carry on RJMII doing machinist "stuff" can be fun!
We have emoticons for welding, barfing, and doing weird things with sheep. There really needs to be a mad machinist emoticons in there somewhere
Posted by: 94TEENV8 Jan 24 2010, 09:28 AM
If you have CAD capability I can send you a file that I used to make my 914-8 emblem, if I can still find it. Let me know!!
Steve
Posted by: RJMII Jan 24 2010, 10:29 AM
Steve; PM sent. Thank you very much!
BRODIE: I have version 20.6 and version 23. I was playing with 20 3 or 4 years ago while trying to build a router table. (dozen surgeries later I gave up on said router table, hence the smaller machine) and I decided that I'd upgrade to 23 at Christmas when I bought the mill. I saved bobCAD's number in my phone so each time they call I know it is them and I just hit the 'ignore' button. LOL Thank you again for all of the help!
Clay; I've got your request noted. =o)
Mark; Oh how I would like to come visit you at work and see the huge machines that carve clay cars. Those are the ones that got me interested in multi(3+)-axes CNC machines.
Jamie; It looked huge compared to my tiny mill; now it looks small. (and I noted that you would like the set of wheels when I get them figured out and carved)
Underthetire; I stand corrected. Thank you for the links! I had fun drooling over the REAL huge machines!
Posted by: bdstone914 Jan 24 2010, 10:36 AM
How about a 914S emblem just like the 911s had. I know technically a 2.0 914 isnt really an S, but it makes me feel special.

That soo much fun. I was a a shop that I installed a Horizontal line system in. 15,000 RPM CAT50 taper machines. 3 of them linked with a robot, and 80 pallets. They would fill up a 2 CU YD hopper every 20 minutes on each machine. Nothing beats high speed machining! Sounds like machine guns with the chips hitting the enclosures!

I do like the older OSP controls, the new ones seem complictaed to me with the new panel. MC50VA i'll bet. Still, nothing wrong with a good old reliable Fanuc. I could see why you'd want Okuma, they are built in Nagoya.

Ok, ER is a STD collet now days, where a MT (morse taper)2 is not. However, you would need to clamp a ER in a MT2, since that is what your machine is designed for. I would go with MT2 collets for what you are doing. The drawbar just threads in to the back of the collet and sucks it up in to the spindle. The taper on the OD of the collet will "crimp" the cutting tool and hold it very well.

And, ER32 is too big for what you want. You'd want a smaller ER i think. ER20, or even a 16.

Great! Thank you. =o) I'm currently the winning bidder for the MT2 collet set (hopefully it stays that way).
That's going off of your recommendations. thank you again.

For testing programs get some "Machineable Wax" It's harder than candle wax and you can re-melt it.

Thank you!! I will certainly keep that in mind. =o)

Got some test tools coming my way. I'll pick them up this week.

My machinist friend here in town has been working on my stepper motor mounts.
I thought I'd add a couple of pictures of it as my path to making the emblems progress.

Hey that there LoveJoy coupler you are using. Do you ruin lots of the rubber inserts by having space between them like that? I use L075's on my gold dredge. If there is ANY space there, I'll eat two rubber inserts per day.

That's a picture of progress of it being built and fitted. It hasn't been run at all with the steppers attached. take a closer look at the pictures and you can see how the mounts are adjustable. The gap for the lovejoys will disappear.

I have some used but excellent condition 6mm and 8mm roughing and end mills I don't need any more I could let you have...maybe in exchange for a couple of those green Matchbox 914 cars sold in the US now.

I'll find a couple. PM your address to me.

Here we go! My mill is now set up with the cnc stuff. My XP box (yellow computer under the Wii) is running the mill and the 3d scanner.
in this picture I'm scanning a wheel that BKLA sent to me. (thank you, for the use of the parts to scan!)
The end mills that underthetire offered showed up as well, and thank you for them, as well. they are certainly appreciated.
The other picture was the first thing that I carved with the mini mill; it's my 5 year old's name. He was all excited that we had the machine set up and was once again begging me to build Wall-E. We carved his name out instead.
(I drink out of canning jars, I make sure to drink a LOT of water)

here is a picture of the scanner screen while it scanned/aligned the first round of scans for the wheel.
this is going to get edited and turned into a Fuchs, then machined out of aluminum. (or plastic, wood, or wax for the first couple runs, to make sure i have the code right)

mid-april. I have to order some more pieces parts for it and print out the instructions again.

Hey, I forgot about this post. Good to see you got it going...I still have some end mills for you (in 6 and 8mm) roughing and finishing end mills and also some 3D ball end mills in 4 (2R), 6(3R), 8(4R) and 10(5R) I can let you have, they are used but in excellent shape....I still need those wheels for the RC cars....hint hint

RJM11,
That is so cool! I got a Taig mini-lathe 6 or 7 years ago. Nice to have when you need a custom bushing made, etc. I guess you know a mill can be used like a lathe also? You can go to the TAIG web pages and gets LOTS of info on mini-lathes and mini-mills.
Have fun,
Tom

Not to make any of you sick, cause I know i was, a guy here bought 3 Hardinge tool room lathes from our company auction for 1500.00! Another guy picked up a small Hurco CNC 3 axis mill for 500 bucks. ( small as in 15X25 travel). Wish I had a garage i owned !

almost ready to start taking pre-orders.
I'm getting much closer, and am able to carve the 914-8 out of wood.

@Tom; thanks for the tip! The electronic piece that is going off to Dr Evil is my 4 axis controller. The wheels will be getting made on the setup you're referring to. i'll look over the Taig site for sure, anything that helps me learn the easy way is a good thing.
@underthetire... sounds like a couple of people scored some really good deals. how often are the company auctions?

Once a month. I need to get on the list myself. There is some really nice slightly older machines heading over to the recycling center this week through next month.
