I hope this is the right forum for this type of post. I saw some other SWUG posts when I searched in this forum.
The Palm Beach County Florida SWUG will be having our next meeting tomorrow (Tuesday the 14th) at 7:00pm EST. Anyone from the South Florida area who uses or is interested in...
OK, so I managed to figure this problem out, or at least a workaround. I figured I would post this in case others have had the same issue as I have.
When any solid part that has holes is imported into BobCAD, the circular edges of the holes are split up into 2 half-circle arcs. I was able to...
I am using BobCAD-CAM to create tool paths.
I have imported a STEP file of a part that contains holes. I am trying to sketch points in BobCAD in the middle of these holes so that I can use the points to make a drilling tool path.
The problem is, I am unable to make any sketches in reference...
I'm working on a product with a client that involves a small container that will hold about 1-2cc of various essential oils. Most likely spearmint, tea tree oil, and/or peppermint. Ideally the oil(s) will be completely saturated onto an absorbent pad, so there shouldn't be any free-flowing oil...
hmm, I would think the flame retardant additive would be able to withstand higher temps better than anything :-/. Do you think the steam may be somehow reacting with it or something?
I think I'll try the SAN. I'm not really familiar with that material. How is it compared to PP and HDPE in...
I'm not sure. Like I said, these were prototypes, so I just ordered some PP from McMaster. It is black, temp range of -40°F to +200°F, and they have it labeled as "Flame-Retardant Polypropylene". They were unable to furnish any sort of datasheet.
Do you think the steam would have any impact...
I am currently in the process of designing an enclosure for a disposable product that will need to sustain prolonged exposure in an environment that has temperatures of 180-200F with a large amount of steam. Expected exposure time is between 10-24 hours continuous.
My first thoughts were to...
So I'm in the process of applying for a summer program with NASA to work on the SPHERES project.
For those not familiar with the SPHERES program, it is basically an initiative put forth by NASA to use relatively cheap off the shelf technology to develop small micro-satellites and drones for...
I changed the follower a bit making it shorter and thinner. I looked at these images:

and it seems that the follower wants to be about half the thickness of the grooves. I made that change, and also made it a bit more shallower by putting...
Oh yea, I probably should have uploaded both of those.

I'm working on a project right now that involves a reversing screw mechanism. I am trying to design and model it in SolidWorks, but am having trouble getting the profile of the threads right. My problem is that the follower seems to be getting stuck at the end of the threads where it is...
Thanks everyone for all your help and suggestions.
What I wound up doing is changing my design to eliminate the need for the metal channels. Instead of going with a triangular shape, I went with a "box" shape and was able to just use acrylic sheets and solvent-weld them together at right...
