Here's the drawing for the clamp plate.

Alright, so school is done for the week and I can actually start making this thing. It all starts with a hunk of aluminum, 1"x1"x1.8". Sized. I realized that I needed a 9/16 hole. I don't have a 9/16 drill bit. I don't have a boring head either. So I drilled a 1/2" hole on the mill, and...

I think a mark of being truly good with technology is being able to get by without it. I can say that I use my computer all the time. I use a calculator. I listen to music on an mp3 player. I use a word processor. But I also learn to do everything without that. I take my math tests (calculus)...

Looks to me like a Jensen.

That's really neat bogs! Did you have any kind of indexing for the positions, and if so, how did you do that?

Very slick, I like the knurled thumbscrew. That gets me thinking, maybe I should learn to use that knurler that's just lying around...

I've been boring a lot of blind holes recently, and decided that I really need a carriage stop. I had a Tumico micrometer head lying around, so I can make a micrometer stop. I'm drawing it up beforehand, to hopefully minimize the amount of scrap I'll make. Here's the top. My atlas has a flat...

Very nice. A snowflake pattern, just in time for winter. ;D It looks like you have an X3 mill, is the 6" RT the right size?

I'm really looking forward to seeing how this comes out. I'm currently in the process of looking at spindle options for mt CNC build, and have been eying those ER16 chucks. What size controller do you plan on using?

Awesome, good to know. Thanks again.

Thanks for your feedback. I used to do a lot of shipping of electronics projects back and forth between the US and Canada, and have yet to have a good time with it. I end up with an hour long ordeal hassling with the folks at my post office. So although I would like to, for now I'm stuck. I'm...

If anyone is interested, I'm selling my #100 Armature chuck on eBay. Two came with my lathe, and I really have no need for them. If you're interested, here's the link. http://www.ebay.com/itm/Jacobs-100-Tailstock-Armature-Chuck-/170701174026?pt=BI_Tool_Work_Holding&hash=item27be95350a

The cylinder looks beautiful! I guess the tapping gods were smiling. :) Very fast build, at this rate the engine will be done in remarkable time.

One of the things I like about machining (other than making cool things out of lumps of metal) is the thought process and problem solving. I really enjoyed your sketch of order of operations; I think I may start doing that. Best of luck with that cylinder, looks like a challenge (at least for...

I've got a few of those. I can use them on so-called "no-calculator" tests in math class. :big:

Fantastic work, I can't wait to see how this goes! Yes, I do like your tap wrench. :)

I was gone all last week, and so I couldn't get to work on this at all. But here's a fail. I was making this bitty piston, and left a tad too much hanging out of the chuck. It seems that with diameters like this in brass, anything hanging out of the chuck is too much. Hrm. When I began to...

I really hope it works. :-\ The smaller they are, tthe faster they go!

Hello all, I got some more time in the shop today. So Here's what I got done. I drilled the air passage and then counter-drilled for an air fitting. I then drilled the air passages for the cylinders. I can't remember where I read this trick (maybe here). By holding a laser up to the main...

Hi all, My first engine build was a rocking engine. I'm not sure what it was about that thing, but the "blow over" piston really captivated me. I wanted more, and building another wouldn't satisfy that need. So I decided to build a dual rocking engine. And as though that wouldn't be enough of a...
