Scratch build Nitro tethered race car, second try!

[CertifiedMike]

This is about where the woodshop project would deviate from its original plans to more of a "custom ashtray/paperweight" design. My many years of grade school art class prepped and high school wood shop really helped to fine tune the final design!

I'll be watching... from a distance, mind you!

Tried my Bosch hand held detailing sander yesterday, 'the type that vibrates' and it didn't work! I had previously given it a hard time doing another job and after a while it had stopped, I assumed from over heating, but having left it a while to cool it was still dead.

Today I took it apart, traced the circuit but found nothing wrong, checked the armature windings at the commutator, all seemed of equal resistance, I was about to strip it for bearings and bin the rest when I searched Youtube and found someone who had the same problem and had traced their fault to a broken connection on one of the field windings. So I took mine apart again and found the same issue, one of the windings was open circuit, (there are only two!). The wires leading off into the windings are very fine enameled wire and the ends are crimped on to a small terminal, mine had been severed at the crimp, there was just enough slack in the wire to allow me to solder it back on and 'over soldered' the others and it now works.

Saved me a bit of money, although, up until then I was quite enjoying choosing its replacement.

Now you've got a little more time to save up for the "nicer but more expensive" unit that you'd picked as a replacement!
Maybe your repair will keep it sanding for another 5 years?!

I love when I save things from the recycling man!

Yes I hate waste, especially as it’s had little use, hopefully it will hold up.

Sanded its bottom.

Looks like it’s in need of Filler next, went a bit mad with the dremel, vision was impaired by clouds of sawdust on my glasses, that’s my excuse!

That's shaping up nicely (pun intended)! Looks really good. Hows your finger doing?

The wooden car body now has filler on it, looks like a roughly iced cake. :0)

Finger is healing well thanks, tender still, but in one piece

Sanding day today

Then a quick coat of resin, it’s starting to less clinker boat like. It might have been better to use slightly thicker wood because after sanding its very thin in places.

I managed to nick the opening around the cockpit, some repair work required and a few low points and dips need refilling.

I am hoping to sand the resin fill high spots and give it one more coat of resin.

Looking killer man!

 

[Doom!]

Looks kind of like Ivory.

Shh! Don't get Roog in trouble!

Its really shaping up nice!

Still no idea what I am going to do with this, the club members say make a mold from it, and make a GRP body, I would prefer to lay thin tin or aluminum plate over it and either solder or bond the parts together.

I think I would be happy with the character of the metal plates.

I like the idea of the tin. I don't know if the work involved is to complex though.
A metal body is sort of rare these days!

Soda cans might be easy to use. I think metal body would be cool looking. Need to watch how much weight you add no matter which route you take.

Wheelie yellow is the first thing that came to mind.
I know the van isn't as pretty as I imagine this car to be but it gives ideas and shows how durable a tin r/c can be!
Here's how I found him in case you're interested @Roog
...good for a laugh if nothing else!

Classic tethered cars have diecast metal bodies, but competition cars tend to use thin grp, I’m not a big fan of GRP, it’s so Involved

I have worked with resin and fiberglass but no plastics were involved. Glass was messy for sure!
You seem like an "old school" kind of guy (as am I) by the way you like to machine things yourself.
The tin is "old school" also. It would go well with the theme of the build.

Finishing the plug is me buying time, I’ll turn to full on procrastination next !

I’m off to see if I can buy metal sheet at a sensible price, might look out for a big metal can
