The Ultimate Air Manifold The title may be a quite bit of hyperbole, but the concept arose from my dissatisfaction with the air manifolds that I've been using at shows for the last few years. It's an aquarium manifold. Under $10 each on eBay. The valves don't adjust very precisely and...

I'm moving up to a larger lathe and thought I'd see if there's any interest here before I Craigslist or eBay it. Located near Philadelphia, PA Grizzly G0602 Metalworking Lathe Purchased new July 2011 With 3-jaw chuck 4-jaw chuck Faceplate Steady rest (never used) Follow rest (never used)...

Elmer’s #29 - Mine Engine Mine, All Mine Episode 1 And you thought I’d gone into hiding. No such luck. Couldn’t resist starting a new build. I’ve been looking at this one for a while and the plans have migrated to the top of the pile. After looking at the size (small), I almost did a 2X...

I'm sure I'll find some things that need more final finishing, but for now, I'm calling this one done. http://www.youtube.com/watch?v=ophwl190KJg

Boring Head Presetting Tool If you’ve followed (and how couldn’t you) my Elmer’s #33 build log, you saw that I used a boring head to mill the inside and outside curves on the crank. The question came up about how the head was set for the radius. When I did the operations, I guessed a lot...

I was thinking about 4-jaw independent*chucks the other day. I get that a better quality 3-jaw self-centering chuck will (or should) have less runout and hence, be more accurate. Since the part in a 4-jaw is being indicated to (ideally) zero runout, what is the advantage to a good (i.e...

OK. Now I'm officially confused. Help me out, please! After centering a cylinder bore with the Blake Co-Ax indicator, I set up a bolt hole circle on the DRO. My usual procedure is to use a spotting drill and just tap it on the part to make a dimple (just as a visual check) at each bolt...

Elmer’s #33 - Mill Engine Cross HeadCase Episode 1 I’ve yet to make a mill engine and,since it’s been nearly 24 hours since I finished the cross twin, and I have that extra flywheel casting… I usually build from the base up, so the base and sub base are first up. Dykem’d (is that a...

Calling this one done. The build log is here http://www.homemodelenginemachinist.com/f31/double-cross-elmers-34-cross-twin-engine-22384/

Beware This eBay seller is selling plans for Elmer's Open Column Twin. I've contacted John Tomlinson who is (as far as I know) the only legal source for the plans. Also contacted eBay. http://www.ebay.com/itm/open-column-twin-steam-engine-plans-/201020098666?pt=Model_Kit_US&hash=item2ecdbb486a

I was marking a part's centerline for drilling. Dykem. Clean surface plate. Set Starret Digital Height gauge to .250. Scribe line. Move the part to the mill. Haimer ZeroMaster in a collet. Find center. Locate hole position. My usual procedure is to press the center drill as a check. The mark...

Double-Cross Elmer’s #34 - Cross Twin Engine Part 1 Other than polishing, the Liney RV-2 is done. So, here we go with the next engine. I’ve always wanted to do a horizontal engine and Elmer’s #34 - Cross Twin Engine seemed intriguing. After reading the drawings, so that I understand how...

I have this philosophy about tooling. Most of the cutting stuff is import (read "cheap".) The measuring stuff (mikes, DROs, DTI) is where I'd rather spend the money. The end mills aren't getting dull quickly on a diet of brass and aluminum and, if it doesn't fit in the Drill Doctor, it gets...

Now I have to disassemble and polish, etc. http://www.youtube.com/watch?v=x7pQkXCZ7VI

Liney RV-2 - Four Heads Are Better Than One Part 1 - Crankcase I know. I know. It’s been 5 days since I’ve posted a new engine build, but I had to wait for Richie, my UPS guy, to bring a chunk ‘o 6061. After the double-wide RV-1, I’d had enough of those large parts and...

Found a good rate at the Best Western Westgate Inn. I've stayed here before. Nice people, free breakfast. 10 minutes from the arena.

The Liney RV-1 at 2X scale is done. Total build time 7 days. The build log is here. http://www.homemodelenginemachinist.com/f31/liney-rv-1-new-double-wide-22045/ and a video http://www.youtube.com/watch?v=JIfMfQppDZk

It seems as if, when I near the end of a build, I begin thinking about "what's next." I have 4 sets of plans on the bench, but, I would really like a power crossfeed for my lathe (Grizzly G0602 10x22.) After I made the power carriage feed (independent of the spindle speed) I realized the...
