WordPress updated & Twitter sidebar fixed.
Also note it contains links to my YouTube channel where I’ve started doing video work-blogs. Will try to get them crossposting to the main blog here automatically if I can.

Productivity is still rather spotty, but I am getting things done in dribs and drabs. I think all current “projects” stuff is in the workshop again now, and a big pile has been thrown out.

The biggest single thing is commiting my mind to doing just one thing for a while, then I can get on with it.

Maybe I should do these weekly? What do you think?

Anyway it’s warmed up a little. Workshop’s averaging about 10c when I get down there. Done a couple of test-casts and they look alright.

Will be casting up some from the still-intact moulds tomorrow with a view to ship on Saturday. Others are in progress.
The first couple of layers of filler have gone down to get the new moulds sorted. Another couple of days of that and they should be built up and finished enough to start laying on fresh silicone. After that I make up the new fibreglass jackets. So all being well, should able to cast the full range again by the end of next week.
Only potential delay I’m aware of will be if I run short on silicone or fibreglass resin. Should have enough of all regular resins and foam to fill current orders.

That said I know I’ll need more silicone to account for some more new items, but I don’t want to do piecemeal orders and get charged a tonne on separate shipping. Since TOMPS can get it to you in 2 days, it’s not worth it. I can just find other things to do in the meantime.

Webshop prep has stalled a bit again, but I’m aware we may be loosing internet here for a short while near the end of the month as our phoneline has to be physically dug up and replaced. Launching only to be unable to receive orders would not be good, so it’s not a huge concern. I would still like it to tie in nicely with a complete set of new moulds though, plus some stock on hand.

New soldering station also arrived on Monday, so with the donated oscilloscope and a repaired multimeter, I’m good to start work on the mecha-ears project again, as well as a few other ideas people may be interested in.

Also a complete fluke-find has gifted me with a LOT of leather in a texture that’s almost identical to vinyl leather I’ve previously used for texturing paw-pads. There’s enough I should be able to revamp the whole range and keep the distinctive look as well as push the foam-filled prototypes to a standard item.

Finally as promised, an entry about the horns!

Okay, so some of you will have seen these at MCM Expo, surface-finished, mounted up to headbands and listed in three price bands. Since then I’ve got the final blank horn prices sorted. They’re all individually priced now, along with their various options.

These horns are made for costume use, so are designed to be lightweight. They have a thin outer layer of polyurethane resin to preserve surface detail, which is then reinforced within with a rigid polyurethane foam. This provides a good balance between light weight, excellent detail reproduction and good damage resistance. The horns however can still be trimmed to length with a serrated knife or junior hacksaw.

Use of a double-density reinforcing foam is available as an option, but will increase item weight. Integral resin colouring is also available.
Foam-rubber is sadly not yet available due to poor surface reproduction, and issues getting them out of the moulds fully intact.

Please see this image for examples of surface detailing effects: EXAMPLE

Here’s the group-shot:

 

Basic pigments (Red, Blue, Yellow, Black, White, Green, Orange): £1.00

The load of disposable vinyl gloves arrived this morning and I thought “fantastic! I can get all the last fibreglass work done tonight afterall!
I go out, come home, hit the workshop and open the gloves.

And find out I’ve ordered 200 in Small size. My own fault, didn’t read the listing right. Fuck.

More have been ordered, but they’ll take at least 2 days to get here.

Tomorrow I’m going to have to go and find some at retail prices because I can’t wait that long for them.

I’ve also got the roto-caster dismantled to a large degree now. I’ve spent some of the would-be-fibreglassing time working out how to make the inner motor drive two spinning frames instead of one. Should be able to get it all fixed up again in a few hours tomorrow. This way it’ll actually be able to do what I intended it to.

Running worryingly short on time now though.

Fitted a HDD up to the machine I found a few weeks back, have loaned it to the hackspace as the new lasercutter PC since the old one died.

Picked up a 99p ankle brace from Walthamstow. It’s worked wonders. All I’ve noticed is how uncomfortable my new shoes are.

Looked over the brazing hearth at the space again. The adapter I brought appears to be visually similar but a slightly different tread. Have brought home all the fittings to try and work something out.
Frame needs welding and there’s some firebrick missing. Possibly asbestos. :P

Feeling pretty shattered. Going back to the space tomorrow afternoon to look over the diffusion pump that’s being donated. Will take the bus in. Will be a LOT cheaper.

More tinkering today.

Pulled the frame apart and flipped it over to give the motors more ground clearance and enough space for a trailing castor.
Rather than cut up the push-scooter bearing tubes, I made a new longer one from a piece of old vacuum cleaner nossle and bolted it into the clamp from an old satellite dish mount. That gave me some bolt holes and nice steel plate to attach some more scrap 1″ box section to as an angle-block. Another couple of bits of smaller box-section went on top again to provide rigidity.

I’ve run out of M6 bolts now though, so will have to get some. Studding would probably be better though.
The motor assemblies were already made up, so it’s really only the frame that’s the product of the last couple of days.

The motors look a little wonky because they’re not bolted down properly. Neither are the bearing-blocks, which’ll need three more M10 carriage bolts. Probably want to put some fibre washers between the motor mounts and frame to help prevent damage to the aluminium gearbox housings.

Here it is with the existing battery box roughly in place.

It’s a large box because it contains a commercial van battery (12v, Lead-acid), as well as positive and negative bus-bars, keyswitch, automotive fuse panel and emergency-stop button on the rear hatch.
May had a high-current plug to it too to allow it to provide jump-starts. If I find one of them laying about anyway.

No motor controllers as yet. I still need to test the stall current of the motors (12v, 180Watt, ~220rpm geared).
Wheels are ten-inch pneumatic sack-barrow wheels. Freewheeling hubs were previously ground off and fixed hubs with a coupler-dog brazed up and bolted on.

Got some aluminium car-phone enclosures with surface-mounting holes that should take a controller each quite nicely.

Whatever this ends up being, it’ll be pretty powerful and be able to go a long way.

Need to make mounts to secure battery box and fork-extensions to turn the current front wheel into a castor. Wanted a pneumatic castor, but there’s not enough space under the frame currently. Maybe later.

Will keep my eyes on the river; see if a shopping trolley turns up. A trolley basket could be a good addition to it for the moment.
