Yeah I will try the heat resistance of the rubber before and then see if I need to replace them with screws.

Regarding the seal. In fact the lower frame is beneath the forming platen level. But it´s less differance than it seemed in the planning process. So yes, I too were thinking about this problem.
I came to 2 possible solutions: First would be to use the router and route around the forming platen so that the main table plate there is thinner.
Second would be easier: Running a sealing rubber along the forming platen.On the place round the platen where there are no holes. You understand what I mean?^^

Even easier.. Glue and nail triangle wood stock to the edge of the platen. This raises it, gives a pointy seal edge and is cheap, fast and effective. Fill any small gaps with silicine house sealant.. Lets not overthink stuff...... lolol

Today I finished my lifting mechanism. Waiting for the plastic sliders to complete the frame/lifting part.
Then only electric wiring and plumbing is left on the To-Do List

looks great Benjaminvegeta I wonder how tall are the side posts (from the base to the oven) may be was the picture, but I get the impression that the distance between the oven and the platen is more short than what I've seen in other pictures

by the way this distance is not affected? in other words, if is too short may not allow the plastic to cool or take longer than usual?

anyway great job!!!

Hi,

the posts are 70cm tall from platen to bottom of the oven box.
I first was going with 100cm, but that would have been a little to tall. Would have needed a longer lifting mechanism that would be hard to reach in top position.
I´m not afraid that the plastic won´t cool. I think the 70cm should be enough space.

hoo ok, I thought it was very short distance between the platen to bottom of the oven (much shorter than 70cm), maybe the perspective of pic gave me that impression, but I think that is good height 70 cm

congratulations again, I will be wiating for more of your progress Wink

thanks for share!!!

Today I built a (ugly) little control box for the oven.
Oven is running. Very Happy

The hole is for a vacuum gauge

Yesterday I was a little worried because I had the feeling that my oven is not becoming hot enough.
So today I measured. At 210°C and rising I stopped because my gloves were to hot for my hands Very Happy

So I´m really relieved. I was concerned all night if I would have to rethink my oven

Today I did the plumbing of my machine. Mostly I used copper pipes. For the connection of vacuum pump and vacuum meter I use vacuum hoses with extra thick walls. These are from motorsports supplies and were lying in one of my boxes.
I chose a 2-stage system with extra valve for the tanks
Of course I already tested my vacuum part of the machine and luckily there are no leaks. The pump reaches its lowest pressure point and when opening the valve there is that nice sucking sound from the platen Very Happy

Here are pics:

In right upper corner you can see that the copper pipe is going on. It´s going to a closed bung which gives me the opportunity to upgrade to more tanks in the future:

Vacuum pump:

Then I glued some wood stripes into place around the platen which will help to form the seal. When the glue dried, I will seal the stripes with some silicon.

Complete view of the machine:

Nice Work! You're doing a great job of adapting to what you have available. Being able to add more tanks is smart thinking too.
