just cleaning up the parts so I can take some pictures the gear is the middle reduction gear in the gearbox
Topic: do you have a 3d printer ? (Read 1474 times)
Have you thought about making a mold and getting it cast ? I think that could be quite a cheap method.
He did, and they quoted him an INSANE price for casting the gear.

it is the middle gear there is another plastic one on one side and a aluminium one on the other will take more picks in the morning
thanks
thanks
no problem. Whenever.
here are some picks of the gear I took on my phone so they are not 100% http://s1315.photobucket.com/user/zackclark70/library/
I will measure it when I go around my friends later today

Sounds good.
sorry I haven't had chance to get the measurements yet

Have fun with it. I would build the mating gear and drive it with a variable speed drill to test.
Good idea to find any mistakes.
This may be a lot tougher than you think. From the looks of that image, the root of the gears may be on the order of 0.1 mm. It's going to be tough to get a mill small enough in diameter to make the cuts, and long enough to do the full depth of the gear. The surface finish of the teeth is critical so that you have a continuous contact surface. If it's not right you will generate hot spots and the plastic will weld itself and tear locally.
It will be a good learning project... get yourself a reference on involute geometry so you know what you are trying to accomplish.
Disclosure: I did quality assurance for a manufacturer of automatic transmission parts a lifetime ago.

You are correct, this would be a big pain for a noob.
I do not speak all of the buzzwords of a textbook machinist, but I am not a student and I know what I am doing.
I would never attempt to cut this on 3 axis.
Cutting on a 3 axis would mean I would need such a small bit, with a flute length equal to the width of the gear. Even peck drilling would make that... a slow and foolish way to do it. 4th axis all the way!!
A milling bit of 1/32 = 0.03125
1/16th = 0.0625
An engraving bit with a point of 30 degrees will be accurate to 0.001 with no effort. (On a 4th axis cut)
The right engraving bit for the teeth of the gear will be something to figure out later. Perhaps a custom cut HSS bit made just for this.
Plastic would be difficult and weaker than aluminum so I have urged the OP to allow me to make this with aluminum.
Perhaps Derlin.
I would not attempt to cut this on 3 axis.. but rather from a 4th axis to get the teeth cut smoothly and easily as the gear rotates around.
A 3 axis would take far too many passes with a much too thin bit.
With the 4th I can use a nice fat ANYTHING with a nice sharp point so long as it is the appropriate angle to cut those teeth.
Fewer passes too.
I think it would be best if I send you the part so its 100% the same ( I don't 100% trust my measuring lol )
I would me looking for one to start with as I would need to test it if it works well I will be looking for 100 in the 1st big batch
I will take some pictures and send them to you so you can see how it needs to be
once I have sent the picks and mesurements u can give me a quote
it would need sending to the uk will I take picks in the morning when there is good lightthanks
zack
Sounds good.
So correct me if I am wrong. You are in the UK, or you need dropshipping to the UK.
You will send pics and measurements first for a quote before you send the original?
But you do not trust your measurements and want to send the original for me to measure and make sure I have an exact clone.
Take your time, I will dust off the CNC and get everything together in anticipation of making some gear widgets for you!
=)
Making just one as a proof of concept is a perfect idea before making a bunch.
cubify.com has a service to print for you online known as cloud printing for 3d objects, but it is quite costly
I have a 4 axis CNC mill and can do it in aluminum or steel!
Plastic breaks.
I have autoCAD, and visualmill premium!
I can CAD, CAM and Gcode like a boss.

what country are you in ? I would be able to send you the part that needs to be made
to everyone else I will get back to you if this falls threw
thanks to everyone that has replied on this thread
I live in Lynnwood, Washington, USA.
Yes you can send me the part. Sounds small so it would be cheap. If it was large or if you feel lazy I would say don't bother.
Just take a few pictures of it for me of all points of interest. Then put some calipers on it to size it up.
Send me all the measurements and I could make a 3D model of it in any file format you can read, or show the model to you on youtube.
I think Aluminum would be best for this, light, and corrosion proof.
I already have scrap that would be big enough to cut down to this size.
How much are you willing to pay for this?
Do you need just one of these parts?

I just saw your picture for this gear, I will need to order an engraving bit for cutting the teeth depending on how you want this made. (Something I need anyway)

I can 3d model from a paper sketch if you want (specifically for 3d printing, kinda poor timing for me to actually print it this week as i brought my machine down for maintenance, am busy with other projects, but in the next few weeks I'll have it back up running and would be able to make high resolution ABS prints of parts.
Perhaps someone else is already doing it for you, but in case you need some help, let me know

You need to take ten pictures from all angles and use cubify.com software to convert it to stl files and hope that it will work

I could do it for $10 + shipping. I'd have it shipped by Friday. PM me if that sounds good for you.
i have a plastic sprocket approx dimensions are 10mm x 12mm does anyone have a 3d printer that can print one ?
( needs to be as strong as posable its a part for rc car that they havent made in 4 years so are very hard to get )
i can email picks and send the part to you

my school has 5 3d printers we can use, if I remember correctly they charged 6 dollars per cubic inch, might do it if its worth my while, I can CAD it pretty quick.
