Electric Axe featherweight - first build of FW

[khevolution]

can i ask where you got the ball casters from? thinking they might work nicely, and at £1.50 you cant really argue even if they dont.

TBH I just found them on eBay, but there was an Irish seller linked to by another forum user on their build diary that was ireland based and not that much more expensive, will link below with their quote


From project squirrel in Featherweights forum

I don't know of any featherweights that run castors [...]
The Honey Badger does use a castor on the front and previously did so on the rear when the wheels were located in the middle. Strictly speaking the rebuilt version doesn't need it., it has enough force to move on its HDPE base with the motors driving it along but I find it helps make it a little more controllable. I use castor balls in mine (http://www.ebay.co.uk/itm/301529661473) rather than a wheel to help with ground clearance.

I will possibly also get some from this linked seller as it's Ireland. And I don't have to wait a week or 5

Hey Nat,

Just seen you've had your TZ85As delivered. If you're using the brushless ones, instructions for Simon-King them are available - we put the set we used on our website (https://www.arc-robotics.org.uk/2017...urnigy-tz85as/) which may help.

If you get stuck - please shout. As we established last weekend, I'm probably one of your nearest roboteers.

Will defiantly be in touch, just got my fuses today so will start cutting the chassis and wiring stuff up, should be good.
I also received my Ireland based ball castors, and well.. the ball bearings feel gritty so they are not the best. Will try and clean them out otherwise I shall just use them to scrape along the floor lol.
100 amp fuses arrived also so I am covered there and have a 30 amp fuse for each of the ESC I have.
Just need to get my cnc mill running on the table and then I can machine out some nice HDPE panels!

IMG_2757.jpgIMG_2755.jpgWell it's been a busy morning, was hoping this was the case last weekend but I left a USB stick at work with all my designs on...

However this weekend I have been able to set up my mill and machine out 2 plates from HDPE
Although I had to change the dimensions and design slightly as my bed only goes to 300mm long, 19mm too short.

Results look fantastic and it slots together nicely

Looking good Nat!

[Outlaw]

Looking brilliant Nat. Can't wait to one day go against it with Ratatoskr when they're both completed.

So an update.

I managed to clean up all of the floating black specks of nylon from the dining room table, dining room, kitchen, hallway, front room, stairs, bedrooms... you get it, yes it goes everywhere!

Have cut out several pieces from my sheet of nylon, using printed templates to get the best arrangement to save material. Pieced together and slotting well. Few issues with spacing for brackets but repairable!

For the base, I'm going to have to get it laser cut as I have decided wisely or not to get some interlocking going on with the base.
I still wanted to prototype this so I was able to use the local backspace lasercutter, well local tomy commute.
Have laser cut the rest of the panels I need and it is looking good.

Just need to find the right supplier to do the laser cutting base and see if my mountings are going to work.

Worried about the weight...

[Ocracoke]

Looks very neat and tidy so far, how heavy is it at the moment?

[Roboteernat]

I'm unsure as to its weight currently, but will be taking it to work to weigh in on the scales there. I know I will have to do some sculpting out of the hdpe parts, so I'm expecting it to weigh more than the limit once e hardox panels are in. I have all my electronics now so could do a full weigh in, and see what I have left to play with for the hardox...

The wood lbs weighs more than the metal, but I can get that from the cad
