Hi all! Remember me? I've been off playing with model airplanes for a couple years... stuff like this: http://www.rcgroups.com/forums/showthread.php?t=2257072 (I know - I should build a 1/6 scale VW engine for it :rolleyes:). Anyway, I've always been interested in the magnetic levitated...

25 some years ago I buried a 1/2" copper pipe from the house to the shop, and used it as a natural gas line for many many years. (Don't worry - only compression fittings above ground, but soldered connections underground...) It's about 30' long. A few years ago I smelled a leak outside when I...

So Friday afternoon I was making myself one of Bog's little precision scrap thingies when that storm hit, the power went out, and the lathe stopped spinning. The electric company's web site estimates we will be back "on" July 7th (today is July 1st). Grrrr... The 100 degree temperatures...

Pretty obvious, I suppose, but had me stumped for a while. I dismantled my Webster engine a couple weeks ago to replace the piston "O" ring, put it back together but couldn't get it to run worth a darn. Piddled with it for a while every evening for the past week or so but it just wouldn't run as...

So now that I've got a Webster under my belt :) I'm thinking I'd like to build a hit & miss engine. Relatively easy would be good... Ideas?

A few weeks ago LMI's special of the week was their #2258 "Economy Air Spring Kit" - I went for it. I didn't really have any problem with the operation of the stock torsion spring gizmo, but the longer rack sounded good. So this afternoon I got around to installing it. I followed their...

I'm sure I'll be doing more tweaking, but my Webster is essentially done! Thought I'd take some pictures of it while it's still nice and shiny & has that new engine smell ;D http://www.youtube.com/watch?v=52KyFs8Reqw&feature=youtu.be Build log here...

So I'm thinking maybe I'm ready to do my first IC engine, and the Webster seems like a good place to start. Kinda apprehensive to start a build thread on it, as I don't intend to hurry or anything... but what the heck :) Since I had a suitable hunk of cast iron on hand (from a boat anchor) I...

So I was having a few beers with a machinist friend yesterday and he described the process of engine turning to me. Today I've tried it out: Started with a little disk of thick leather and glued it to an aluminum arbor. Dab some valve grinding compound on it and press into the work in a neat...

I've spiffed up the plans of this: http://www.homemodelenginemachinist.com/index.php?topic=17946.0 They are kind of spartan, but I think one could probably build off of them with a little imagination :) The first two PDFs are the drawings, the third is the two pictures from the thread in...

http://www.youtube.com/watch?v=9LuJy9oOHUs&feature=youtu.be Pretty darn satisfying, as all "runners" are ;D If anyone is interested I'll make the plans presentable and do PDFs. (Correction: that maximum speed is about 1,100 rpm. Forgot I had one of those optical tachometer gizmos...)

After a couple of attempts I was unable to make a workable built-up crankshaft for "take one": http://www.homemodelenginemachinist.com/index.php?topic=17090.0 I might try it again now that I've straightened up my mini-mill per these excellent instructions...

Essentially the NAMES finger engine with the flywheel running on a jackshaft at twice the speed of the crank: I can't help myself... ::)

Following up on my contribution to the"Gear cutters" thread over in Questions and Answers, here is most of my gizmo to employ my first gears: Yet to be done are a couple of screws through that hub on the left-most gear into the gear,plus a handle on the shaft extending back behind same. The...

The instructions merely say: "ABS: Set increment (INC) (relative) zero" Huh? Can someone explain? Maybe some examples? ::)

I'm just kinda winging this ::) Wanted to make a "complicated" crankshaft, and an in-line twin will require that. I've been thinking about it for a while, but not making much progress on the drawings. So this afternoon I just decided to go ahead and get started on a major part: ...So we...

Finished, with matching hardware and a proper low base: ;D

I got a 2" "screwless" vise for my mini-mill a couple weeks ago - now I'll be able to use it: Just thought I'd share, as I've never seen hold-downs like this before. I was going to make the more normal ones with the pins that go in the holes but changed my mind 'cause this way seemed stronger...

Feeling the need to make a gizmo, but not wanting to take on a major project, I thought I'd try my hand at a finger engine :) I'm following the plans of the "NAMES Vertical Finger Engine" (TDP 2/2005), but with some cosmetic differences. Kind of at a standstill now waiting for fasteners to...
