new build atom

http://m.ebay.co.uk/itm/311311059992

a thread for the odd question i may have.
First has the name atom been taken?
Also anyone tried these speedo's ive linked their rated at 16v max and have you ever overvolted them?

i use them in night fury and scruffy but there are a few software versions on ebay so only some work properly

Ok. i was gonna try some as a punt as they were cheap. I have a scorpian in another robot so will use that.
I am replacing a motor on my k9 but i need some reverse screws for the drills can these be bought anywhere seperately.

unfortunately the supplier i got mine from seems to have stop selling them each esc will happily run 2 drills on 4s and barely get warm after 3 min

They kept coming loose on k9 so i threadlocked them. Think i overdone it with the threadlock and ruined the screw getting wheel off lol. My spare motor also seems to be missing the screw i think their m5 or m6 reverse thread.

I had a set of those ESCs in Hardwired 1 and they had a brake function on, but happily took 2 drills each. They did also eat themselves after I put them in my beetle. They work fine in Scruffy/Night Fury from what I've seen but it's all really dependant on you getting the right ones which as far as I can tell is pure chance unfortunately...

thanks for comments i think i will pass on them and just share my scorpian between this fw and k9, not a problem.

Ok. I need to bend some 8mm thick strips of hdpe about 2" wide. I have a heat gun for paint stripping is that a good method? Or put it in the oven? Wondered what others have done and will it hold its shape once cooled.

I use a combination of L angle and a dedicated (Leister) plastic bending/welding heatgun.
Or for smaller bits up to 110mm wide, I take up my bender, and go with the heatgun again.

Ady if you're still after reverse thread screws I have a couple spare you can have, m5 ones.

Yes please sam!!

Quick question, when building a chassis out of hdpe, should I use threaded inserts on all joins? Including inner bulkheads and floor, or do some people use wood screws in places. To go into a full combat event

Neither ideally. The screws will wear down over time and the threaded inserts pull out. Barrel nuts and bolts are the way to go for HDPE.

Ok thanks for advice

For places where barrel nuts won't fit, you can use Tee nuts:

They are a type of nut insert that is pressed in from the far side of the HDPE and will not pull out. I have used them for years without problems.

ooooohhhh I forgot about these! :-)

I'm stuck with mounting a small titanium scoop/lip to front of robot, I'm mounting it too hdpe, any ideas what would be the best option for full combat

Lots and lots of screws with a nylock nut and a wide fender washer on the back. If the titanium is thick enough, use countersunk screws; vertical spinners love to bite the heads off screws.

Ok thanks I was using 5 mm. It's to get the front to give zero ground clearance

For 5mm thick material you can use at least an M6 countersink screw. Depending on how thick the HDPE is you could use those Tee nuts I mentioned earlier to save space.

Now I got some other tv projects I've been working on finished I thought I'd post the specs of my first fw I've built since having prodigy (2006 championship 3rd place) and prodigy evo (the first single toothed fw spinner)
I have quietly accumulated most parts over the last 12 months, concentrated on getting a new lathe, pillar drill and other tools into my workshop. and this week I'm starting the build now I have some spare time and space.
I had retired but I have sons who want to be roboteers so I decided to dust off the cobwebs for a last go!
4wd invertible rambot
4 bar electric lifter
20mm hdpe sides and rear
10mm hdpe lid
8mm hdpe base
5mm titanium laminated in Kevlar scoop/ flipper weapon

Basically a 4wd version of storm 2, I'm looking to get completed in 8 weeks and will post some in build pics as I go.

Theirs no fancy cad drawings or cnc machining here just basic tools and equipment to again prove you can build a competitive machine (for any newbies)on a basic budget using simple tools!

Good luck, looking forward to the build diary

Here here lol :-) the kitchen step is your best mate

"Basic tools and equipment"
"A basic budget using simple tools"
"Lathe"

One of these things is not like the others :P.

Haha lathe is a basic tool isn't it?

Put it this way: as a student, I have Google Sketchup, but I don't have a lathe. ;)

I read that as "Googles Ketchup" and was like man... They've broadened their horizons...
I don't have a lathe either but many CAD packages and 3d printer, so I guess it depends on what you prefer/find easier.

My lathe is pretty old, I use it on the wheels
