I see in the 4th pic you have the engine up and running!
Terrific build thread Lex.

Talking about the engine, there is a small roadblock. I've been testing the lighting system circuit before installing it. I was too ambitious trying to power a high-power LED through button cells (the 1025 variety) and could not reach the desired brightness. I will try using 4 in parallel, failing that, will try to use a capacitor cell instead.

Could you share the "particular type", please? I have the dental machine, but the plastic I was recommended to use (Thermo-Forming Material, Clear-Temporary Splint .020" ) does not produce good results (bubbles from trapped gas).
Thanks, Gene K |

Just a quick comment on vacuum forming. Bubbles and milkiness are typically due to moisture absorbed by the plastic from the ambient humidity. Gently heating prior to heating to form may remove the moisture. You will want to experiment or only vacuum form in low humidity conditions.

Thanks for sharing your experiences. I am not sure what other factors affect this. I have no idea PVC sheet could perhaps come in different types at all. Will definitely try the moisture point.
What bubbles have you been seeing though? I have experienced nothing like that...

Papermangler, I've used your suggestion to "gently oven bake" the plastic to remove the air/moisture, and it helped somewhat. However, that's an aggravating extra step I'd like to avoid, especially since the results are not entirely positive/predictable. That's why I'm hoping Lex's "particular type" will work for me ... if he can identify/share it. Gene K |

It's erm, from... Taobao, you know, the Chinese eBay. I am pretty sure shipping to the States from Asia is too much of a hassle (and also such an overkill for a few plastic sheets), so I would recommend trying to find something equivalent in the US. There must be many more vacforming experts on the forum so it's worth asking around.
If the admins don't mind, here is the one I use. https://item.taobao.com/item.htm?spm...d-fdfffd6217fb

Thanks for the link, Lex. Yes, the shipping is absurd.

The link to any item one uses for their models is just fine to be shared, no need for caution or asking if we don't mind.
Knowledge sharing is free, i don't put any restrictions on that

This stuff is kind of overpriced, but it's the equivalent of what Lex used. I'm also looking at some clear badge holders, they are clear PVC and some are .25 mmhttps://www.amazon.com/Midwest-Clear...5+mm+clear+pvc
