Well after pouring it all in the cracks, I needed to level it all out a bit as well on the bottom of the planks. It's snowing like a ******* here and so doing in my house seemed like a good idea. It wasn't

but hey ho, can sweep up.
I haven't used an electric plane before, watched a load of YT videos to try and help and while I got the base pretty flat, I had one mishap, which I literally watched to avoid, but still did it... I'll explain in pics.
First, I had to make a mold
Mold check...
Then I needed to plane the bottom to make the plank on the right flatter on the bottom, but also the top looked a bit messy, so thought I'd do this, too. Should have just left it in hindsight lol
Looks much better... until you spot the GOUGE in the bottom right corner...
However... it's not THAT deep. And Once the pours are all done, I am going to ask the saw mill to put it through the leveler anyway for a couple of reasons:
1. I don't have one and I want a totally true surface, which is hard to get with a hand electric plane when you're a total n00b
2. Even with my attempts at leveling these planks, I can see that it will still get under the boards, which I don't think I can totally avoid at this point, so will need to be leveled on the bottom anyway.
3. It will no doubt give a better finish for me to then sand progressively to make it as perfect as possible.
I want the best finish I can get so using someone to do that for me seems to make sense. The wood is so thick anyway, it's not like it'll make it thin. The mistake is a few mm deep. Lesson learned.
Next up today:
- Test the temps in the garage. Hoping it's about 15c for resin down there.
- Clean out the mold, make sure no dust etc.
- tape all outer edges of the mold in case leakage
- clamp the wood planks down hard to the mold both ends
- mix up first pour and YOLO
- Use heat gun for air bubbles every 8hrs as it starts to cure
Will do first pour today and leave it 24hours. It won't 100% cure in that time, but tacky enough to take the second pour on top. It might take me 3 on the depth of this I think.
I was super annoyed at myself for that mistake but at the same time, I know it can be rectified and shouldn't make a difference when it's all leveled at the end. Just annoying when you mess up.
