Hey Kevin, looks like you are getting very close. Go look at the pictures in the sergent engineering groupsio page “Treeing 3D prints”. Look at the IMG_1095.jpg picture. All the 3D models are designed

Hi Ed, Sorry for the delayed reply. Unfortunately, I no longer have the ability to make these. The design for these actually came from a customer. You can make something that functions similarly with

Hi Todd, I see nothing from you. Please make sure you sent it to info@...

Hi Tim and all, I’m very happy to see everything going on here. I’m not surprised the prints for the Sharon coupler did not come out well. Those files are what was used for the die cast tooling and I

Die casting requires a dedicated steel mold for each variant of part. Those molds are very expensive. That’s why I always used investment casting for the specialized stuff that I didn’t expect to sell

Hi Todd, Unfortunately I have zero of those left. The lower shelf castings are diecast. That’s why I can continue to offer the SBEC87 couplers. Thanks, Frank

Hi All, I removed the S scale page (and the tailor made page) from the website because I was editing the website anyway and that was an easy thing to do and I figured it would hopefully reduce the num

Hi Nathan, Everything in the bulk packs is done by weight. I actually target 150 of each casting (more if I’m having issues with defective castings) and 150 balls and springs. Sometimes there are a fe

Hi Bill, I should have 20000 new sets of EC87K/EC87KB castings in two weeks if all goes as planned. ENC87KB will be back in stock at that point as well. Frank

Hi Peter, Your order shipped this morning. You should receive a notification from Paypal that includes the tracking number shortly if you haven’t already. Thanks, Frank

Hi Cliff, You just reached me. Don’t be shy about using the group for this. It seems to be the most reliable method. Diecast couplers are in Zamak 3. Unfortunately, its pretty much impossible to solde

Hi Todd, et al, So far I have found no solution for manufacturing the investment cast items. I have not given up completely. However, the whole thing is pretty discouraging and I’m not dedicating as m

Hi All, Trying to answer a bunch of questions at once... Alan: Really bad/unfixable. I wouldn’t say that. I can’t stand to not work on a problem. Time frame for solution is totally unknown though. Chr

Here I am! The new printer appears to be a bust and I’m pretty much out of stock on all of the investment cast stuff. I haven’t given up completely, but I’m not sure what else to try. I wish I had bet

Here I am! I couldn’t find any emails from you lately. Maybe my IT department lost them. Anyway, I have 7 packs of the FC87M040K in stock. Making more may take a month or so while I work the kinks out

Yes. But its not AutoCAD and not Inventor. See https://www.autodesk.com/campaigns/fusion-360-for-hobbyists

I changed the subject line here because this is shop talk and a little off topic but is in response to LJ’s question and something I am still passionate about. I don’t believe a run of the mill (FDM)

Hi All, Let me restate what I have said before and give an update. I did say I would eventually get out of the coupler making business. Wheels are slowing turning in that direction now. I have put all

I’ve received a few emails from worried customers. Sergent Engineering is NOT going out of business any time soon. I think it best to address worried customers in this public forum. So maybe you’re ri

Ryan, SF couplers are recently now available as a stock item. Most email communication seems to be working now, but I do still get several emails a day indicating my message (that I obviously never se
