Yeah, moving forward looks good. That blue stuff is interesting. How does it compare to old school plumbers putty? You might want to pressure test the tank before you spend too much time on it. Just run up low pressure on the tank and see how well it holds over time.

Keep it up!

Felix...

I HIGHLY recommend that after your plumbing is hard connected, that you use big globs of silicone or acrylic house caulk on the outside of all the joints. Thick is better than thin. Remember that you are stopping stuff from getting INSIDE the plumbing from the outside. I always preach oversealing stuff and its always worth it to avoid all leakage... Hylomar might be fine, but big globs of cheap stuff are proven to be foolproof. Scott..........

In case some of you are wondering, right now I have had to set aside the table project. for now. I have been asked to build an Episode 3 clone armor. This will *really* help me buy my oven from doug as well as the remaining supplies i need to finish up.

I need to also get some steel tubing for the frame(s). Im up for suggestion on which style to use as far as lifting the frame that holds the plastic over the mold.


thanks!

Heya Doug! I have just been going over my thread and a lot of the new ones to catch up on knowledge. Im currently designing my clam to hold the plastic and then the uprights for the sides (for it to slide).

One of the things I have been considering, after looking at some of these new threads Im wondering if I should just go with a new tank, but its hard to find a 30 gallon tank. Lowes has 10 gallon tanks for 34 dollars but im not sure 20 gallons will be enough.

Im pretty excited again. I built that Armor I said I was going to do Seen Here as well as a few other projects. But now I really want to get this done. She is beggin me now Smile

I was worried about adding on to such an old thread. Hope thats cool.

cheers Smile

EDIT:

I think I may have screwed up when making my Platen.

The current size is 34 1/4 X 22 1/4

Im finding it difficult to design a clam using 1 inch tube to utilize sheets of platic 2X3

Im assuming a buffer of 1/4 to 1/5 inch from the edge of the clam to the edge of the platen?

I know sheets come 4X8 so it may cost me more? Can you shed any light on this? thanks

i dont understand the fascination with huge 30 gallon tanks. 5 gallons works great. look at the volume of the part you are forming. you only need two or three times that volume.

so if I got 2 10 gallon tanks like Stormtrooper guy, I could pull a 10inch high mold?

Its about VOLUME not height.

A Gallon is 231 cubic inches

A part 23 X 10 in size, 1 inch tall is 1 gallon
if female molded.

Male molds are a bit trickier to figure because
you are removing the volume between the
plastic sheet prestretch tangent lines and the
mold surface, NOT the volume inside the part
when formed.

Its simple to visualize if you just slow down
and take a look at what you are doing. Imagine
a sheet of rubber in your plastic clamp frame,
lower it over the part. It will seal against all edges
of the platen. You are removing the air between
the imaginary rubber sheet and the mold surface.
Go ahead and buy 30 gallon tanks if you wish, but
I seriously doubt once you really look at the process,
you'll need that much.....

Scott.

cheers

Well there was no need to do any welding, I simply bought a few 3/4 inch plugs and sealed them in.

I also bought fittings to plum two 3/4 inch holes to a single 1 inch (to stay consistent)



I used a union in the center but for the two platen flanges i will use a short piece of high vac hose instead. I dont want any pulling or stress on the flanges.

btw the blue stuff you see on the fittings is like plumbers dope only high grade thats used on airplanes


What a great way to increase airflow!
That never dawned on me.
