2.5" Vulcan Side Frame

Post by BClemens » Wed Apr 29, 2020 8:44 am

Almost finished with this...what a chore it has been. Sometimes working with CAD is like a video game; trying numerous ways to 'beat' the game to accomplish a satisfactory result without crashing the software (feels that way anyhow..). Next will be the CAM programs to machine the inside and outside patterns using REN shape. Need to take a break from this for a while... but - stay home! bc

Nice!

Mental exercise or future castings?

Thanks! The intent is for future castings. But then also another attempt during the 'stay home' time to remain somewhat sane. I have made iron castings a number of years ago and don't have fond recollections of that so will probably contact a commercial foundry. (356 cast aluminum will probably not be satisfactory for these). That means the match plate will need to meet their specifications. There are no cores although there are a couple of places that could have added detail by making core-prints and the core boxes... complexity costs at a foundry. bc

Couple more...this is drawn in solids as completely individual parts so can be locally updated. This software has no lettering so each letter/number had to be drawn as a mechanical part. Talk about dark ages...but at this stage I'm used to it and cringe at the thought of learning a new software.

The journal boxes will be a part of these side frames as one piece. Not so sure that bolted journal boxes would be such a good idea especially with a derailment. That is where core boxes will be needed.

Everybody likes a photo...(these are all in perspective) bc

Very nice! Will you be making casting available for purchase? Hint hint.

Considering passing these solid cad models off to an industrious sort who can/will make castings available. bc

One way to avoid this is to do the lettering in another product like Inkscape, which is free and supports saves in svg/dxf. Import the 2d, scale it, position it, extrude it and then combine/merge it. You still have to go back and do any tapering/filleting to individual edges and faces, but I have found it speeds things up and allows you to easily do things like putting text on a path or adjusting kerning/spacing of letters.

Thanks! I'll definitely look into that. It's a task to line up the lettering plane then build each letter. bc

What CAD software are you using?

I'm using Kuboteck KeyCreator 9.0. CAD/CAM. Old version but it works very well. I've done many, many CNC machine parts using this software - with Mach3 and the embeded software in a Haas CNC machine too. Also used it for running a Sciaky electron beam welder...wrote my own post processor for it. It is good 3D software with features that I still haven't used. bc

Fusion 360 is free to Hobbyists. It's an excellent CAD program too.

Funny I was just struggling with an issue modeling something today and I reached out to a friend of mine, he had a great quote:

"3D modeling is like wresting with a bear. You will never be stronger with the bear, but you have to be smarter than the bear". Very true!!
