Great Scott! It’s another Hoverboard build thread...

[Retrograde Orbit]

Managed to pull the casting out without too much bother but it is looking rubbish... But I placed it on the board and took a picture, just as a test fit.

Looks about right I think.

 

[Retrograde Orbit]

Made up a mix this time without pigment. It has poured much better and no mad dog frothing this time...

 

[Retrograde Orbit]

Okay, I took a photo or two...

And, still using that rubbish casting, I took another photo of what the overall thingy should look like.

I'm actually quite pleased with how this is turning out!

 

[Retrograde Orbit]

Second casting pulled and test fitted again...

Guess there is a lot of sanding, filling, priming, painting and sealing ahead of me!

 

[Retrograde Orbit]

Future planned work:

1) Route out channels beneath the battery pack so the clamps go under it
2) Take a silicone mould of the completed battery pack
3) Get painting all the cast pieces

When will it get done? I don't know, I'm making this up as I go... (Ten points if you know the movie!)

 

[Retrograde Orbit]

Righty ho then...

I worked on some better decal graphics which were originally supplied by an RPF member named Roland. They are amazing, although I did have to redo them as my board does not seem to be quite the size that his decals will fit.
Unfortunately I could not just resize as it was not uniformly linear in both height and width.
In the end I had to get the background image sized correctly and rounded at the ends as needed. Then grab each piece of the graphics and resize/redesign so that they looked right and fitted my boards dimensions.
It took bloody ages, but luckily Photoshop and Foxit Reader did not let me down.
Obviously the top and bottom decals are a bit different in length due to the tail section. But I allowed for this in my calculations.

This and the upper decal were printed off in posterised mode using Foxit Reader and I stuck 'em together so I could do a test fit.

 

[Retrograde Orbit]

Here are the decals without any nonsense on them...

Much better than what I had before, and they fit really well. So I am now pleased, for a change!

 

[Retrograde Orbit]

The battery pack part which I cut out of 12mm MDF has had the silicone mould treatment...

This was left for umpteen hours to cure and was then demoulded. At which juncture, I knocked up some polyurethane resin and poured that into the newly made mould.

And lo, there was much rejoicing...

 

[Retrograde Orbit]

And here is the part, cured, taken out of said mould and test fitted with the other bits. Never mind the odd colour, I sanded it with sandpaper that had red dust in it!
Yes, that is the new decal underneath...

It kind of looks like a hoverboard, no one is more surprised than I. :eek

That's about it really for today, thanks for tuning in...

 

[Retrograde Orbit]

Cast, pulled, sanded and washed. Ready for priming, etc. tomorrow...

I foresee much filling and sanding in my near future...

 

[IxMAGICx1]

I am loving every second of this!! Thanks for the updates!

 

[Retrograde Orbit]

Do you have any idea how hard it is to put a bend in polyurethane resin...? :eek

At least I know where all the bits will be fitted now.!

 

[Retrograde Orbit]

First coat of primer, and there are all the imperfections!

Followed by slapping on the filler.

Then, the obligatory sanding to follow... Ho hum.

 

[Retrograde Orbit]

I am loving every second of this!! Thanks for the updates!

You’re welcome. I just wish someone else was doing all the work! :lol

 

[Retrograde Orbit]

Much sanding, filling and another couple of coats of primer later...

I think someone more skilled than I will have to get the remaining pits and scratches out!

 

[Retrograde Orbit]

After studying my reference pictures of the prop board, I have come to the conclusion that the silver coloured part of the "plate" is not just the base painted. It looks as if there is another circular piece just a couple of millimetres in thickness, painted silver and stuck on.
It is really hard to tell, but I am sure it is that way.

So, this morning the hunt was on for something that would fit the bill.

Luckily I found a bit of 2mm white styrene which had enough so that I could cut out two circles with a 50mm radius, giving me about a 5mm gap all round the main base.

 

[Retrograde Orbit]

These were lovingly sprayed with a quick blast of red primer.

For once, luck was on my side and there was no sanding needed as the styrene was sanded prior to the primer being applied. So I was able to give it a layer of chrome paint fairly quickly... And here they are. Came out fairly well.

These need to be glued onto the main plate after I have sprayed it up.

 

[Retrograde Orbit]

Started with a final very light rub down and washing the parts in washing up liquid to get rid of any grease spots.

Decided to start with the black, as I thought it would be easier to mask off for the red clamps later. Unfortunately, I think I was a bit heavy handed with the spray... Grrrrr.


There are no runs but there are some bubbles and the corners look like there has been some run-in... I will have to wait a long time before I can mask and paint the red for the clamps. My, fault, so...

The imperfections on top are going to be irrelevant, as those silver disks I made earlier are going on top! So at least one thing has gone right.


Actually, this went quite well...

Ready to be painted purple. :woot:

 

[Retrograde Orbit]

And this is a quick look at what the silver disk will look like on the rest of the assembly...

Might just do the job.

 

[Retrograde Orbit]

Despite the crappy black paintwork (which I can pull back once totally dry) it is coming together. So, here is a quick picture of where I am with the underside at the moment. I have also redesigned the underside decal for the second time as it was quite a bit off in the placement of the lines... Yeah...


But it's almost spot on now.


So, my attempt below...

Closely followed by a photo I took while we were watching BTTF II last night.

Obviously, I have not finished painting it yet, but I think (hope) the overall layout is close. But what I think is unimportant.
What do you lot think of it?
