I kind of like the notches in the handle.. I'd leave them :)

[HighVoltage]

[QUOTE=~ZOMG;39497643]Wow, that's an amazing improvement![/QUOTE]

All I've really done so far is go at it with a wire brush then gave it a good sandblast. It should look awesome after I fix up the handle and give it a good coat of paint.

[QUOTE=garry;39497741]I kind of like the notches in the handle.. I'd leave them :)[/QUOTE]

I'm leaving the notches, its the little pockets from when it was rusted that I want to smooth out before I paint it.

[~ZOMG]

I think that's what he's referring to. I agree, really. They wouldn't affect the knife noticeably, and they're a nice touch.

Routed my first piece, of 24, off my template using a very complicated jig that worked perfectly. I'm excited to get this project completed, I'm loving the way it looks.

Here is the original concept I threw together last year, finally getting to work on it. I don't have it clamped at the same angle in the physical copy but it's the same.

I've got to make 22 'triangles' for the design, but I might end up doubling that and making it a kickass coffee table instead. Looking through it will be crazy.

[Serj22]

In regards to fixing the pitting and denting (likely from the rust) of the knife handle:

Bondo. Then finish with a little glazing putty. Should be hard enough to paint and clean.

You can stop being amazing whenever you feel like it, Ajacks...

Also, does it fold? It looks like it could fold, which would make for an interesting portable piece...

[Ninja Duck]

Ajacks, you're amazing, and that 3D designing you do looks so useful for projects.

Also Garry, I'm jelly of the modernism you have over there.

[woolio1]

Garry and Ajacks should do some sort of collaboration for his office. They seem to share some of the same tastes in design.

[Ajacks]

Designed a new entry door for my house, based on my concrete coffee table. I think I need to make this happen. I didn't add a door pull, I don't know what kind of style I'd want to use.

Also, white panels would most likely be nixed, although they look nice they would impede visibility.

[ewitwins]

Are you thinking just glass then?

[Killuah]

I'd use something like this:

My mates birthday is coming up and I felt like making him a present.
Before I left work I broke two forklift pallets by "accident" and threw them in my car so I could make this:
[img_thumb]http://i.imgur.com/0xuFTes.jpg[/img_thumb]
The plan is to fill it with various hats and somehow burn the words Mann Co. into the side of it as he's really into TF2 lately.
Quite pleased with how it's come out so far as I didn't want it to look pristine

Just make him a little Steam Wallet with real/fake money inside to go along with it :v:

I got my first ever 555 chips yesterday and made a PWM circuit based off [url="http://www.instructables.com/id/Yet-Another-Simple-Pot-controlled-555-PWM-generato/"]this guide[/url]
I'm still quite inexperienced with electronics, but this is looking to be a very fun hobby.
Hooked up a laser and beamed it around my room. Now I need to find somewhere that sells small mirrors, so I can make a laser spirograph.

Last night I got really bored and took apart a computer charger that puts out 12v DC at 1amp and hooked up each end of wire to two gator clips. Then I got some graphite from a mechanical pencil and clamped it to one gator clip, and there you go. I made a mini DIY carbon arc cutter.

I was able to slice aluminum pie plates in half without even touching it and aluminum coke cans too.

Tonight I might take an empty coke can and cut out some art pieces that you cant get using a knife or some scissors.

Maybe I should make a plasma cutter our of a car battery charger for my next project. I was surprised at how effective and fun that little thing was.

[Ajacks]

Pulled this awesome aluminum chair base out of an aluminum scrap bin that was in the foundry next to my studio. Totally couldn't let it get melted down, it'll polish up beautifully and is extremely similar to the base used on Eames lounge chairs. Now I just need to make something to use it on.

Just getting the parts for my voltage multiplier. I want to make x-ray photographs but I need at least x-rays with an energy of 60 keV.
20kv doorknob caps, 640 picofarads.

REALLY loud when discharged... Going to need that mineral oil and 75kv wire. That wire is a little bigger than a penny in diameter.

Careful with the X-rays. Those things cause cancer!

I have plenty of lead shielding for the tube, and plan to build an aperture encasement big enough to fit an intensifying screen. I won't be in the room either.. but regardless i have dosimeters, geiger counters etc to check for leaks , calculate dose rates, and most importantly, monitor my dose.

Cut out two more blanks to route in a day or two, I need to go buy more MDF though, but now with 3 blanks and the template clamped together you can start to see how it will look. Really excited.

More excited though that I got to see one of my woodworking professors eames collection in his dusty back office! I walk in there and see three amazing authentic eames chairs, this one is just beautiful, build quality was amazing. He has new leather upholstery ready to be installed, and he's going to restore all the aluminum. Apparently he has an already finished one at home. I was so envious, he was very surprised to see my reaction to seeing them, knowing what they really were and appreciating them for what they are.

If I'm thinking what he's planning, I'd say that he's going to build a vacuum chamber with the door knobs as electrodes, the potential difference of the electrons in the tube will create bremmstrahlung radiation (X Rays in this case).

Assuming the worst, he'll be creating some hard x rays (Due to the 75KV potential difference, 75kev = 16.53pm wavelength)

Saw this video before, that guy is a nut. I'd never fire a tube without any encasement. I'll post up some of my tube housing later today. I leave the room just in case though.

What I don't have is a proper ionization chamber, but my use of counters etc is to check for leaks, and give myself an idea of the strength of the field. I do have a dosimeter for monitoring my dose, which kind of acts like a ion chamber (quartz fiber dosimeter).

I've already determined the level of safety using a 10 uCi Am-241 source, which has a peak around 60 keV and should be a good gauge of the thickness needed.

I meant 75kv rated wires, the multiplier gives 60kv. Still, quite penetrating compared to even 30kv.

[Killuah]

Wavelength and voltage all well and good but maybe could post some intesity and dosage instead because everything else is useless for safety measures.

I have some absorbtion spectra of lead lying around somewhere let me look for that.

So yeah, I own a Herman Miller chair now. I was unloading some MDF into the studio today with a friend and the retired woodworking professor who had the Eames chair I posted above approached me and since I showed so much admiration and knowledge of herman miller/eames when he was showing my the stuff earlier this week he decided that he'd give me one of the fiberglass side chairs to restore! I was so surprised, really excited to start the restoration project. I want to reupholster it in leather and polish the aluminum base to a mirror shine.

Well, 60kv @ 2ma gives a dose of about 6.3 Roentgens per hour, like 63 mSv /h, or 17.5 uSv/s which is a lot of radiation. 2 minutes near the beam and you will get your yearly dose. These caps and the supply should provide double that, if not more. But again, the rate outside of the room is more or less zero, and the beam aperture is covered with a large piece of lead. Only risk inside the room is scatter radiation.

Another notebook, this time I tried using leather for the cover and experimented a bit by using just carboard for the spine so it would be flexible:

[t]http://dl.dropbox.com/u/46196310/Jake/IMG_1693.JPG[/t]

This one was initially a complete disaster because I miscalculated the width of the spine and had to extirpate some of the signatures for it to fit inside (I'm going to use them for a small A7 book, so nothing goes to waste). I could've just redo the cover, but I was just that stubborn.
Another reason why you need to measure things right before doing anything that's definite :v:

However I managed to make some fixes and now it looks perfect (it has an uneven number of signatures, however).

And also on this subject:

I decorated its cover and now it's filled with bugs:

They're all bugs I've encountered in real life (Save for the spider on the back cover's bottom and the water bug on the top right, which are based on moulted exo-skeletons), and I tried to make all of them to scale, but it's far from acurrate in most cases :v:
