Derp, I meant the other way around. Will fix. Thanks!

This is so cool. Where did you hear about this type of pump? I've never seen anything like it.

There's something about this concept that I find incredibly touching.

Ya, you're right. I'll change it.

I am super-duper impressed. Enjoy first prize!

I didn't want to assume that a beginner would even have a drill press, but in general you're right. I'll add that to the article just in case.

I thought it would be funny.. :)

Interesting! Any chance you could post a photo of that? Or at least let me know the manufacturer? I'd love to look them up.

See, I did see mention that it is naturally sourced (along with emery), but it just seems crazy to me that garnet crystals can't be grown. Maybe it isn't economical because garnet is so prevelant.

Generally I just go a size down for my pilot holes. I just want to clear enough material so that I won't stress the wood and split it.

I'm just curious :) what did you learn?

I know! It's ridiculous! But, well, for some applications you will pay more for their longevity.

I'm trying :) thanks for reading!

About using motor oil, from Wikipedia:"Motor oils have a slightly complicated relationship to machine tools. Straight-weight non-detergent motor oils are usable, and in fact SAE 10 and 20 oils used to be the recommended spindle and way oils (respectively) on manual machine tools decades ago, although nowadays dedicated way oil formulas prevail in commercial machining. While nearly all motor oils can act as adequate cutting fluids in terms of their cutting performance alone, modern multi-weight motor oils with detergents and other additives are best avoided. These additives can present a copper-corrosion concern to brass and bronze, which machine tools often have in their bearings and leadscrew nuts (especially older or manual machine tools)."

What a gorgeous vice!

Nice one!

As @petercd points out, you can get better results with high water pressure! The water pressure we have in the garden is strong enough that I don't need it, even in packed clay. But, if you don't have good water pressure, a hose attachment that ups the pressure into a thin, tight stream will make this go faster for you.

This is beautiful. It makes me want to try and make my own hammer.

Great, simple jig. I appreciated the detail you showed here.

It wasn't cheap...

Yes!

Yes!

תודה חבר! :)

I wish I had known this at the beginning of the project. I don't have much experience with working with metal and drilling the holes was a huge headache.

Check the dome calculator site. You input your type of dome and your desired diameter and it spits out the required dimensions.

Ya, those connections are the thing I worry the most about. They can definitely give a kid a good scratch. But, well, what is a childhood without some good scars?

I know! I was so surprised how great this ended up looking. I can't waiting to use this type of technique again. Have any ideas?

This is really cute. I think I'll make this with my girls.

It's really dead simple to build, actually. For this type of dome, there are two lengths of pipe you cut, and all connections are with a single bolt. It's insanely strong, too. We've had a dozen kids on it at once and it didn't budge.
