  1. More progress on the house number plaque project: - Gating has been removed using the new bandsaw - Edges and corners ground/sanded smooth using oscillating edge and spindle sander - Raised surfaces roughly hand-sanded (100 grit) - Spray-painted black - Paint sanded off raised surfaces Still to do: - Upload new edit - click on pic above to see video of all the aforementioned sanding and sawing and sanding and grinding and sanding and painting and sanding. - repair scratched paint and greasy fingerprints the kids left o
  2. I don't know anything about herculoy but it'll probably work well. Also, it has a really cool name! White smoke is the sign of zinc fumes. Try not to breathe them. If it starts snowing indoors, grab a respirator, I believe P100 filters are sufficient but you should look it up to be sure. Hopefully it won't happen and if it does your fume sucker hose can keep up. Good luck! Kang
  3. I thought I heard my name... Sounds like it's time to get a long extension cord for your shop vac so you can plug it in on another circuit! That's what I'd do if these ingot-chopping sessions are going to continue to be just a twice per year thing... That's silicon bronze, yeah? I did not immediately realize how red the oxidized surface of my ingots were. Just thought it looked kind of golden brown until I set some next to a sample of aluminum bronze (on left in pic below), which is much more yellow. That really made the redness stand out in the silicon bronze (rig
  4. The spines reminded me of my old iguana, Gambit... Which in turn reminded me that Gambit's (hind) legs were more extended to the side to flap back and forth, rather than pointing downwards to walk more like a dog. Just food for consideration, I'm sure you've thought this through already a lot more than I have. The stance you've given him looks good to me, perhaps more dinosaur-like than lizardly. Aaaand we're back to that stegosaurus comparison. Kang
  5. Strictly for medicinal purposes, eh? Riiiiiiight... Just kidding, that actually makes a lot of sense and probably is less harsh in the long term than some of the more pharmaceutical options that could be employed. Have one for me while you're at it, I think I feel a back ache coming on! edit - a couple hours after posting this yesterday my back actually did start hurting, which it continues to do. That's karma for ya, I should not have been joking about this. Sorry if I seemed like I was making light of your troubles. <waits for pain to subside>
  6. Everybody's working for the Weekend by Loverboy. That's gotta count, right? I don't know how much it's really a favourite of mine, but I definitely appreciate the sentiment. Kang
  7. There's one leg at top right in pic that can't be seen from above... I am OK at wrapping my head around molds in general but rubber molds are not my specialty, would that tucked-under leg maybe cause a problem for molding this guy? Just a wild-elf guess, tbh I'm stumped... Kang
  8. The waxes look great. Looking forward to seeing them in bronze! Kang
  9. So, 2 weekends ago while it was oddly warm for a mid-January day in Ottawa and my sand was temporarily thawed out, I finally got the mold made up for casting my sister's house number plaque! There's video on my youtube showing how I made the mold if anyone's interested - I'll link it here. It also shows how I almost destroyed the mold accidentally gouging a bunch of sand out of the top half of the flask trying to open the mold to remove the pattern... I decided to keep that mold anyhow, just means some extra grinding to remove an unsightly lump from the back of the
  10. 625K, eh? Jeez, you could almost buy a tiny little house with no driveway and barely any yard in Toronto with that! Almost, but not quite... Just ask my sister, who the house number plaque I've been working on is for. I'm sot sure which I'd rather have TBH. I'm not set up for (or much interested in) casting jewelry, but on the other hand, big city living is really not my taste either - some of my hobbies don't seem like they'd mix too well with incredibly close proximity neighbours, who would more than likely send the PD and the FD right up my, er, nose, every time I fired up
  11. Aluminum would be too brittle, at least without some fairly complicated heat treatment. I think you are on the right track using bronze. It probably would seem weird to some people to use bronze, ie. a type of metal that is normally saved for the most desirable final products in the world of artistic metal casting, as an intermediate step on the path to producing pewter castings that are easy to think of as mass produced toys, but your reasons are sound, and knowing how much work goes into your greens, it totally makes sense. Frankly I am surprised I haven't heard of others trying something
  12. So if I understand correctly, you're gonna finish sculpting the feet... but is the idea that you'll leave the legs (and arms) as just wire so the cast armatures can be easily posed before slapping putty onto the bronzes to finish them up? You might even be able to bend some of the waxes themselves to pre-pose some of the armatures before investing... or maybe that's not as easy as I'm imagining - I'm not familiar with the wax you're using. Anyhow, good luck with the wax work and casting, looking forward to seeing the results! Kang
  13. Aww shucks, thanks guys :) The big 4-5. Kang
  14. Cool mini! Acetone smoothing to reduce print lines may or may not work, depending on what type of plastic filament was used to print it - ABS plastic, yes; PLA plastic, no. Not sure about other printable plastics, and I have no clue what the default filament choice from commercial printing services might be. Most home 3D printers come with a PLA filament sample; not sure if that is any indication of what the pros use though. ...After reading MojoBob's post more carefully, I should point out that acetone still may be useful for removing traces of wax support material from a PLA p
  15. Geez, looks like I missed a couple replies! Thanks, and sorry to all for not checking back sooner. Fluxes are compounds that reduce the melting points of other things so they will flow better and farther. Other things like metals... or like crucibles and furnace linings. Borax is a flux that is used for bronze foundry as well as brasses and other copper alloys, and (I believe) precious metals. I know it is not used for the type of aluminum foundry work I normally do, but the explanation of the reason why would be boring. I do not plan to melt the chips from sawing u
  16. I picked up a couple of those old RAFM kits at my FLGS a couple years ago for surprisingly cheap when I found them covered with dust looking lonely and forgotten on a high shelf, I am 90% sure this was one of them. Also there was a cool dragon and a skeleton war wagon of some sort. Did you have much trouble assembling this thing? It looks awesome... Great job! Kang
  17. I know caffeine supposedly stunts your growth, but that's ridiculous! :) ...Because they are dwarves, and dwarves are short?... <somewhere a cricket chirps> Hey, I tried, and I haven't had my own coffee yet... Awesome stuff! I don't know how some of you folks come up with these great creative ideas. Kang
  18. Here's the new portaband saw in action, making quick work of turning a giant (~15lbs) silicon bronze ingot into more reasonable sized pieces. (click anywhere on the thumbnail below, it looks like a youtube embed but really the pic is just a hyperlink to the video) Talespinner, if you are watching, I'm curious how the amount of dust/shavings produced compares to the new ingot-cutting metal chop saw that you recently mentioned over in your awesome box-turtle-folk scuplting thread. Thanks, Kang
  19. Hey everyone, hope you all had a great holiday, whatever you may or may not celebrate. Here's wishing everyone a safe and happy new year! I got some new goodies for the foundry under the tree this XMas - some high-temp aluminized gloves that should allow me to skim dross off a hot crucible of bronze without getting a burned pinkie finger, and about 50lbs of Everdur (a silicon bronze favoured by art casters)! I can't wait to try casting that stuff... Also picked up a new portaband saw, which should help a lot with removing sprues etc. from castings, and als
  20. The key to mixing epoxy properly is: step 1: once you're absolutely certain you've fully mixed the two components... Keep mixing. Then when you're done that, see step 1. :) I like epoxy for pinning too, never having had any real luck with CA glues, and I use Jester's old spit-and-poster-tack method to locate the second hole so it lines up perfectly with the first. There's a tutorial on CMON somewhere but I haven't been there in ages, I'm sure everything has been helpfully reorganized over there by now in order to make it impossible to find...
  21. People use vegetable glycerine to make that transparent soap and (along with propylene glycol) e-cigarette liquid, presumably it has other uses as well; I'm sure it can be had online. Can't recall where we got ours back in the 80's when we tried this... Might have been from the drug store or something. If I can find those old instructions I could try to post something here if you like, but no promises - that model RR book is probably either long gone or taken to some faraway place by now. Clever idea, the hairspray thing I mean. Kang
  22. That's really cool... The first one looks happy and the second one looks angry! Kang
