I see a problem with your pt100 element. Its a little bit big (its a to- case, isnt it?). How do you plan to put it inside the sandwich?

Whatever. I like it. Its easy to build something with shops around the corner and money no object. But to do it full diy out of stuff you have laying around or you can get its another thing. Keep on your journey! :D P.s. depending on the programming of your temp controller (switch cycle and hysteres...

I used the 3000. Will propably switch to something else cause i have heat blankets now.

Was little bit too fast for me (on my vaac setup i needed too much time to bag it) and the viscosity was too thick. Didnt soak well enough with triax and small bubbles remained... Like one technican from hp said: you have to slam it into the glass ;) I was working transparent so it was more obvious....

This stuff you dont have to cure afterwards, it will be fine at room temp. Dont like the viscosity for vacuum. But its a good allround resin and its clear. Just wait a few days (optimum 1 week) before you cut and trim your board. The hpe3000 is nice for vacuum, but this one needs some heat. If you b...

Its the hp stuff, isnt it?

If you really like to do it that way and if you like to go fancy heres an idea:

You take an aluminium sheet and weld some aluminium square in lets say 10cm distance to the bottom (like a spreaded cat track). If you use thicker aluminium you can also use countersunk screws. Maybe totally overkill

Maybe it gets better when you include the table into the bagging. With youre technique i assume you get similar problems like vacuum bagging just a sheet of something, the side force from the shrinking bag makes everything concave or convex. But ... just a theory

Looks like its cut out of these:

I think youre main problem is the wiggly lower mold. If youre vacuum bagging it it will create the effect you described. The aluminium possibly will not help enough. How round were talking about?

Are you guys using silicone (pressure, not heating) mats for sublimation via pneumatics? Or just between metal plates?

I think this nozzles are good if you have a 1:1 ratio with your mix. A different ratio like 1:20 will not mix well enough ... dunno if there are nozzles for ratios like that.

If you cant find it i can check you a connection to the look demo stuff from france

Basically, i tried to say that in one sentence

Theres a nice paper from wuerth about this. Just have the german version, maybe theres an english version too.

Very nice work for the 1st board. Congrats!
