Posted: Fri Mar 04, 2011 9:29 pm Post subject: Hello from south carolina. I'm finally back with my 1st pull |
|
|
I have been reading, and reading ,and reading this forum for a few weeks now. And slowly started building my machine over that time period.
Its going to be an over and under where the oven slides back , the plastic will be in a fixed position and the mold will lift up into the plastic.
24 x 24 table. also acquired a vacuum pump 6cf and a 11 gallon tank
i will also be adding another 11 gallon tank (hopefully 22 gallons will do it)
will keep you posted on progress and put pics up if i can figure out how to do that.

Hey Gadget, welcome to the forum! Sounds like you've got some clear ideas of what type of vac former to build. Interesting configuration. Where did the idea come from?

Looks like a decent machine to copy! The geometry for the mold gantry should be rather interesting to work out. Keep us posted on how it all comes together. _________________ DougN - Just in case you're wondering, I got my "rating" legitimately... by posting aimless drivel, useless advice, and pointless questions. |

Good start! Is that a nipple to connect a gauge on the pipe? Some guys don't like the two stage system and I don't often use mine, but when something doesn't go right having the two stage option has saved the entire pull for me! Is the platen MDF? How did you seal it?

small nipple is for vac pump the other is for the tank ,working out the spot for a t off the vac line for the gauge.
the platten is mdf it si sealed arounf the edge as of this moment with wood glue.
wasnt sure about sealing top because of things i read on here about plastic sticking to the sealer (shellac?).
there are 4 layers of mdf starting on bottom with 1/4 inch then 1/2 inch glued to it then a 1/4 frame with supports throughout middle then another 1/2 for the top with 400 holes drilled in it .
so any advice on where it may need sealed would be helpful. |

That's awesome! A very creative design
The best part is the plastic doesn't move through the air, so it won't lose any heat after being warmed up. I'm looking forward to seeing your rig in action!

That looks nice, looking forward to see how you do as well.
You mentioned that you have 9" of clarence, but aren't planning on doing 9" parts. Keep in mind, that the plastic will droop down when heated. So even if you are doing a 3" tall mold and you have 6" of plastic droop...you are at your max....just something to keep in mind.
But great job!

from what i have seen on the internet it doesnt look like the plastic sags more than like 3" on a 2x2 machine .
i'm not planning on making things very deep but i would like 6" of use out of it .
Will someone on here that has experience with a 2x2 please let me know what the typical sag is.....thanks |

Yes, I should have mentioned that I don't have experience with 2x2 sag or any size sag for that matter. It was just something I also forgot to consider with my design...so just wanted to point it out. Hopefully someone will chime in with specific knowledge.
Best of luck

Every plastic is different as to the amount of sag it has when it reaches forming temp. Some sag a lot, some only a little. What type of plastic
do you plan on using? You can always modify and move the oven up a little higher if you need a deeper draw. No matter what we do, most of us first time builders wind up changing our machines to tune them for better performance. I for one did, more than once. Most members are more than willing, even eager to share there machine designs, some are not comfortable at all sharing there designs. Just keep on plugging away and expect that you will get it right in the end.......Fredo
