Hi folks,
Just a quick explanation of my current project. And a chance for me practice my skills at uploading pictures
This is what I'm trying to make. The rough shape of the quad headlight cover was vacuum formed using my DIY vacuum former.
I'm still a long way away from creating the final product, I know. But a lot of things have changed since then. Namely the mounting brackets. The new design is a modular system, these plugs are made of MDF, I've had to use body filler to shape the draft angles, as I'll be using my newly acquired Formech 508DT vacuum forming machine.
Here are my MDF plugs for the headlight brackets >>
My first question to you guys would be, now that I've purchased some 'Pattern-Coat Primer' to cover the plugs with, is how to measure out ( or weigh ) how much pattern-coat primer I need the cover the plugs ?
Would I calculate the volume of the plug ? say, L x W x H ........ then what ?

Many thanks guys,
Glad I got a couple of things right
Would you think that different materials would cause the pattern-coat to set at different levels, such as brushing it onto MDF as opposed to on Glassfibre ? Interesting to hear that you found it to set 'abruptly' Dravis. I may go down to 1.5% in that case.
What did you think I my unconventional way of working out the amount of resin required, such as .......
1Kg of 'Pattern-Coat Primer' per 1m² which is 10,000 cm²
500g of resin - covers 5,000 cm²
250g of resin - covers 2,500 cm²
125g of resin - covers 1,250 cm²
Is that the normal way people work it out ?
Or is there a particular formula ?
I am working with small quantities, after all, headlight assemblies are quite small compared to some of the things people are making on here, like car bonnets. The plugs that I'm making will be for vacuum forming, so hopefully they will be strong enough to vacuum form dozens of parts. I'm also working on the headlight covers, and will be making some out of carbon fibre, so plenty more questions will follow I'm afraid
No doubt I will have to brush up on my math, as there seems to be a lot of converting to do.
Now that I know I need 2% catalyst for my mix, I'm stuck with something else. I've bought one of those MEKP Catalyst dispensers, but it's marked out in millilitres !
So as an example, 10ml is equal to what in weight ? ....... 10 grams ?

If you go straight to the last page you'll see the stage that I'm currently at.
Thank you all folks, I feel I'm now getting somewhere with your your help.
