Nice job! I notice though you don't seem to have a channel or bead in the flasks, to stop the sand from loosening when moved? Or do you find you don't really need it? I'm still on the lookout for a good furnace myself, but I do plan to make some similar ones from alu, although I'm thinking to...

Beaut score Baz! I had a similar one some 20 years back when at the local Reece's to pick up some bits and pieces. Always being a scrounger, I always look in the bargain bins at stores, and I was chatting to the salesguy at the time, while pulling out really useful gas blowtorch fittings...

Welcome Geoff, I love both those shapers mate! Very nice. cheers, Ian

The first thing that comes to my mind is the contact points between the cam and the lifter are going to deteriorate very quickly! 20psi is a fair amount of power for a wooden engine. cheers, Ian

I personally think a large difference between us and the technology of the day, and kids and the current technology being computers, is that our technology required and enabled you to do or achieve things. Thus building motor skills in doing physical work, social skills in meaningful networking...

Very cute! Can't wait to see this one running. Will it develop enough momentum given the size to run well? cheers, Ian

Ha, a vertical cannon! Where did you see the link on ebay? cheers, Ian

That's funny, I swear my kids do too! When I buy batteries I need to buy them in bulk they disappear so fast! cheers, Ian

I found a lot of cheap Chinese ones that are just long coils with no straight ends, but also very thin, I don't know if I'd trust them for any substantial work? Especially as they look identical to the ones in my little furnace, and I've already had two sets self-destruct. Pic attached. I did...

I am just dying for the day I can get my hands on a shaper, I have no real practical use for one, but I would dearly love one nevertheless! Out of all the milling and machining equipment, available (even CNC) there's something about shapers that I find especially fascinating and amazingly...

Wow! Very, very nice Geoff! Love it mate! cheers, Ian

I can't seem to find those ones on ebay Roger, only the tight loop or plain wire Kanthal. Most of the sellers don't list a temp rating either I noticed, just the wattage. Where did you source yours? cheers, Ian

Gus you may like the long neck version, depending on what your using it for. I have both and use them in a standard 20mm linear rail mount, on my cnc for PCB's. The long neck is handy so you don't have to lower the Z axis too low. But anyway, either model is just great, brilliant tools. cheers, Ian

My brother went to Las Vegas over Christmas a few years back, and sent our family a postcard, when he came back, we said we never recieved it. It turned up over 12 months later, from US to OZ, postmarked Japan! I don't know which is weirder, the fact it took over a year and we still got it in...

Great job, very nice work! How well does it run? cheers, Ian

This is just a spectacular engine! Beautiful work and design! cheers, Ian

I was looking for some very small barrel hinges for a project I'm working on, and found a couple of Chinese ones for a pittance, but several US ones, with the ludicrous shipping we've discussed before. This is a good example of the weird attitude some sellers have: 2 x barrel hinges...

The lathe in OZ is just too damn expensive, but the IB/E is brilliant, I changed over to the ceramic bearings and use mine for PCB work. Makes my Dremel look like garbage. cheers, Ian

The gold on the lids might just be the coating that jars have to seal the lid from contaminating the contents. Still, machining metals around carpet can be a bad idea, once bits of swarf get around, they are almost impossible to get out. cheers, Ian

I see this so much myself honestly it worries me no end. My 10 year old daughter is pretty creative and loves all things artistic, but the rest of my kids I'd have to drag kicking and screaming to get them to do something that to them is like forced hard labour. A lot of the problem I think is...
