Just as a matter of interest Frank, if you were to make a slotted knuckle for the S scale coupling you would find a good market for those modellers modelling On2 and also for those doing On30 Puffing

Frank, You are being more than generous! Bless you Dude! If I was a little younger and in better health, I be on this like CA glue! Regards, Dave Houghton

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

Frank, Thanks for the specific reply. I figured as much that you had to use more specialized equipment. It makes total sense to use the resin deposit printers with UV hardening. I just had no

Regarding the Fusion 360 software, it is always free for hobbyists. I've had it myself for a few years now, and I just have to renew the hobbyists license annually.

This is through Autodesk? Mike Conder

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

well, I called and talked to someone and said I was a hobbyist, and that I was not using it for profit based activities, and the person I talked to (of course not using straightforward language) told

First, many thanks to Frank for providing so much detail. It would appear that we are on the cusp of a great leap forward in affordable capabilities. Loren – Where is the FABLAB located?

I have just temporarily assemble several cars, including the (Sergent) couplers. Because I intend to take them back apart, and because it's kind of a pain to assemble everything, I decided not to put

I might be interested in continuing the business, such a great product. I am tired of being a nurse (45 years) and need a new gig to keep me interested. I would like to see how the process works as

I never install the springs, I did once but it made no difference. There in no slag so I don’t see the point.

Ed, I model in HOn3 I do that and I'm very happy with the operation of my Sergent Sharon type couplers. I also use true to scale coupler buffer openings on my scratch built cars. This has required a

If you meant slack as in slack action then the friction springs have little to do with that. Slack as in free sideways movement well it depends on the model. I have some that the coupler box provides

I didn't install the friction springs in most of my cars and locos when I started using Sergent couplers around 2000. I now install them on most rolling stock but rarely on locomotives as I only use

Edward, I've tried the springs,but on the Intermountain 4750 covered hoppers I installed them in,(the springs,I mean),it made no difference with or without the springs installed so I also leave them

I am looking to possibly buy some shelf couplers and was wonder how well they work? Do they make it so the couplers don't slide apart on uneven track or with long cars? Stephen

Yes, just ask me about the three damaged cars I now have when I accidentally knocked one of them over and the couplers took the other two cars with it to the floor! Serious now (that knock over did

Stephen, I have shelf couplers with the single shelf,(SBE), as well as double shelf,(SE),and they work just like the prototype couplers. They won't slide apart and will work on let's call it,
