Who is interested in a repro GE 3-Star osc. disc?

[Noah Britt]

I am trying to gauge the interest for reproduction 3D printed GE 3-star oscillator wheel discs. I am making these to replace the pot metal discs which are sometimes broken or have stress fractures. These will be made out of Nylon 12 40% filled with glass beads for added strength and accuracy. THESE ARE NOT METAL. Depending on the demand, they will probably be $10 to $15 each. I got a few discs printed for myself and I am very happy with how these have turned out. They are spot on with all dimensions and characteristics. They do, however, need some light hand sanding around the circumference if you want them to slide in and out of the oscillator wheel easily. You may also need to slide the brass linkage spacer back and forth in the slide groove a few times before it will slide smoothly. And of course you will need to paint them.

These are replacements for the early model 3-star GEs with the pot metal oscillator wheels. These will not work on the later steel oscillator wheels. If you are not sure which version your fan has, the pot metal wheel discs sit perfectly flush with the bottom of the wheel, screws and all. The steel discs are not perfectly flat and sit below the wheel. They do not sit flush and the screws also protrude below the bottom of the disc.

Just to be clear, I'm not reproducing the whole oscillator wheel; this is just the disc for the underside of the wheel.

If you are interested, please post below.

I’d take one or two if they’re in the price range you mentioned. 

[Noah Britt]

They won't be more than $15 each. Unfortunately the cost of producing these is almost as high as their value, so I'll only be making a couple bucks off each disc.

If anyone wants one of these, go ahead and let me know. The more of these I get in one order the cheaper they will be. I'm not planning on ordering more after these.

[Noah Britt]

Sorry about the long wait but I have been very busy since this time last year and put off this project. I am now ready to order the discs, which I should have in hand about a month after I place the order. The price will vary depending on how many are ordered, but it will be anywhere from $15 each if 2 are ordered to $10 each if 6 are ordered or even less at a higher quantity. I can ship these in plain stamped envelopes (have shipped small parts this way many times with no problems) or if desired I can ship in a bubble package or box at buyer's expense. Whoever is interested, please post below or send me a PM.

I believe I’d rather have a metal part. So I’m going to pass on them for now. You should consider partnering with Louis and have them printed in metal. 

[Noah Britt]

Good idea, I'll contact him and see if he is interested.

I checked....your part can be much cheaper if you scaffold it.  Your model you sent me is not scaffold...I'll fix it and post.  Also, your surface need rounding....higher mesh....I'll fix it.  Let me get some coffee first.

[Noah Britt]

Thanks, you're the man! I guess I don't know what scaffolding is. Also, if you're speaking of the circumference of the disc, I started it off with 60 sides, then duplicated the disc twice and rotated the duplicates a couple degrees each. This rounded it off enough that the product I received was perfectly circular.

The imperfections will show up in metal unfortunately.  I increased the mesh and will have the scaffold ready in about half an hour.  Scaffold means to have each piece physically connected by a thin region so you can cut it.  Your discs....did not have any area to cut and would be a problem after printed.  I fixed it.

 

[Louis Luu]

Done....will upload and see what the cost is.  You need a flat base so the pieces print properly.  After printed, cut the rod off.

[Louis Luu]

That is $14.73 per piece in steel or $8.46 aluminum before shipping.  The scaffold contains 10 discs per scaffold.  You can order up to a hundred and the shipping would still be around $19.

[Stan Adams]

I need one when you get them done

[Noah Britt]

Wow, that looks fantastic! I did have the discs connected but the rods were 0.1mm wide, so they didn't show up on the model without zooming way in. I never would have thought of stacking them in the Z-dimension like you did to cut the cost.

0.1 mm would definitely be a problem for metal printing.  The recommended thickness is 0.6 mm.  That is also a tad bit low for scaffold support due to weight.  I have it at 2.5 mm thick so it act as support while printing.

You can scaffold that way but the cost would be much higher.  Printing cost is determined by print volume area.  The more compact, the cheaper the cost.  But you also need to take into consideration printing direction.

Louis Lou

Please put me down for one sir.

Thank you

[Louis Luu]

Please post if you want one.  I don't really see a big demand for these and will most likely just do a one time order.  Not charging for the drawing as most of the preliminary work was done by Noah Britt....I just fix a couple things....no big deal.  I will only be charging cost of printing and nominal shipping charge of $5 flat.  (Total will be $20 shipped).

[George Durbin]

Hi Louis!

I will take one when done... 

[Lane Shirey]

I’d be interested in a couple of brass or steel ones.

Steel...brass too expensive.  Tell me how many you want.  I'd prefer to do one single order.

Lane, can you please confirm how many in steel you want?

[Lane Shirey]

I inventoried my fans awaiting restoration and they all look good, so I don’t need any at the present time as it turns out.  Maybe in the future depending what I pick up.

Got it.
