Joy and I will be there this year, set up right inside the door to the main hall. We've kicked around the idea of bringing our 3D printer and have it running during the show. If you make it to the show, stop by and say "Hi." We're looking forward to a good time. See you there, Todd...

Hello SmallHaul, That's Paul Breisch's Cornwall Blowing Engine and was offered as a kit, complete with the base. Myers Engine Works has the patterns and the kit is listed on their Web site. http://www.myersengines.com/engines/cornwall_engine.htm The prototype can be found at the Cornwall...

I received the Lulzbot Mini yesterday and printed a couple of rough test prints. Much better having switched to the finer settings. Material is 3mm Taulman N-Vent running at 230C, 60C bed, 180microns, 50mm/sec, w/ 20%fill. Of course, printing a 2"-tall Yoshi. Print time was 90 minutes...

Tin, This one fits your size bill and could be machined from aluminum on your equipment rather than spending $$$ on the full kit. Appropriately named: Hackerbot 2.0. https://opensourcehardware.it/en/61-hackerbot.html https://github.com/OSHW/HackerBot/releases/tag/2.0 You may need the...

Hey Tin, Have you checked these guys out? They also have aluminum corner upgrades and a lot of options for each kit. http://www.ultibots.com/mini-kossel-v-slot-3d-printer-beta/ http://www.ultibots.com/kossel-250-v-slot-3d-printer-diy-kit-beta/ Look like some pretty-well thought out...

I finally broke down and bought a 3D printer. After looking thru way too many options, I ended up with a demo model of the Lulzbot Mini. This was based on good reviews, high-resolution printing, self-calibrating/leveling, self-cleaning, multiple material options, and open-source design and...

I've used two different combinations of materials with differing results Favorite: Freeman 1035 / Freeman Repro One Also Used: Smooth-On PMC-744 and Smooth-On Task 18 The Freeman materials have a lower viscosity and don't have a tendancy to form and collect bubbles on the surface of the...

Thanks for the tip. I've thought about getting the app. ....until now. Todd.

Ron, I would be in the dissenting crowd in the "make the CAD files available" debate. After spending on the order of 300-400+ hours on producing a professional set of drawings, and another 500+ on a prototype, handing over the CAD file to a buyer and then seeing it posted all over the Internet...

Believe it or not, there is a small foundry right here in Hagerstown, MD - Blaine Window Hardware (www.blainewindow.com). They cast red brass, aluminum, and white manganese bronze (aka White Tombasil). They did some casting for me a few years ago for my Parsell & Weed project. I have a...

Dittoing Rustkolector, I purchased mine from S&S Machine & Engineering and have been very happy with it. See http://www.cncengines.com/ It fits nicely in a hand-cream "tin". Enjoy, Todd. Littlelocos Model Engineering

Here's the second video showing the working side of the engine. No cams here as the push rod is connected directly to the timing gear. Enjoy, Todd. https://youtu.be/oJ_aC_2xaCE

Thanks. I did shoot a few videos of the prototype before delivering it. Now, I need to make one for myself. :-) This one was designed by Woody Sins, and cast in 1993, but never built. I built it for Woody in exchange for his left-over castings. Now he has a pair of prototypes (one...

Recently finished the 1/3-scale P&W Vertical prototype. Thought you all would enjoy a photo of how it turned out. Todd. Littlelocos Model Engineering www.facebook.com/littlelocos

Very cool modification. I was thinking the Bridgeport M would be a bit large, but you've solved that for sure. Well done, Todd.

The propane torches can put out a huge amount of heat and can quickly heat up larger items. I scanned the Sievert Charts from my toolbox and posted them here. The largest tip I have is the 2943 at 26000 Watts (88700 BTUH). The smallest tip 3938 at 250 Watts (850 BTUH). My favorite heads...

Really-REALLY nice work! Absolutely beautiful.

I bought a Vernon mill last Spring and am thinking the group would like to see progress on it's restoration. It has been a second project for a while now and is nearly finished. I've been keeping a photo-log of progress and have recently posted the account so far on our Facebook page. There are...
