Tring to figure out how to model the hypocycloidal and epicycloidal curves of a supercharger rotor in alibre cad. This is really making me pull my hair out! Steve H, have you managed this with your model blower?? Im trying to design a 3 lobe rotor for a blower with a 71ish cid displacement...

That was aluminum, but I do know exactly what you mean.

I was hoping to get into the shop today and try a couple of things. So far that just isnt working out :( I really need to take some time off from work so I can get things back on track.

well 9.5 months later and I finally got a round tuit. got the cnc mill up and running over the weekend. First run video.. http://youtu.be/H70V09xrfKI?list=UUSrlSdQ3dLlHlahmmmYbb2A

Well Im jealous. Ive been wanting to build an rov for the past few years but havent been able to find the time (or money) to do it yet. Not to mention biting off more than I could chew design wise with my current set up and experience. Maybe one day Ill get to build it. Until then it will have...

The whole point is to be able to do it at home. You would be surprised how much it would be to sls print that block. Now to do it in lost pla....well now were talking! I printed the SBC block and have plans to cast it using the lost pla process to see what happens. Block printed with full...

Well to throw all the mumbo jumbo aside, I need something that can be printed at 100 microns or less with a much lower thermal expansion than pla. I can get great results with the lost pla casting, but when it comes to certain things (like small blind holes) lost pla just isnt cutting it...

Great find Tin, maybe something like this will keep me from having to buy a new printer. Question is, what does it print like, and whats the thermal expansion like?

Yes, thats me, that video is pretty outdated compaired to what i do now. I want some of this wax!!!! Whats the lowest resolution you can print it at? I typically print at 80 microns, but sometimes will do 50 microns.

Machinable wax, Im curious how and what you used for the wax to print it. I do alot of lost pla casting and would love to have a printable wax filament.

Im window shoppiing for a 3d printer right now. Im particulary interested in the sla printers for thier high resolution. This one in particular has really cought my eye http://www.fsl3d.com/ Ive been researching and im not quite sure if I want to push the button on one just yet. All...

I would be curious to see how a cast firebox works out, and I also understand why they say "dont". I have to think that it is possible to do but would question its long term safety. I dont think I would try it as a pure copper casting. Maybe silicon bronze? Sitting here scratching my head, I...

Geez 11-18-2012 (post #137) I was interested in getting into this team build.....Sometimes missing the boat can be a blessing....

alot of work goes into a casting, but the rewards you get when you have a good casting in your hands is well worth it.

Tempting very tempting...

Beautiful write up!!!

I think I have only used the face plate for machining a few times, and it was a long long time ago. Im pretty sure that at the time I was using the face plate that the lathe was my only piece of equipment so having to find a way to make things work I had to use what I had. I can see where a...

95% of the time I use my 4 jaw independent chuck, it has larger deeper jaws than any of my 3 jaw chucks and I feel most comfortable working with it even though it does take a minute to set up. Most of my 3 jaw chucks have about .005" run out so unless im doing something quick and dirty I use the...
