Anybody else on here visit thehomefoundry.org? I haven't been able get access to that site since the first of the year. I keep getting a server timeout error, I'll try later tonight to see if I can get on-line. Hopefully it's something simple like there been a tremendous up-swing in the...

I've been threatening/wanting to get a resin printer, but one of the biggest things that keeps me from doing it is the smell of the resin. I've heard that the water wash resins have a more tolerable smell. Anybody with first hand experience want to tell me if this is true or not? Don

Got this as an e-mail from these guys today. Never heard of them, but it MIGHT be worth a look-see. Don Are you buying parts from McMaster-Carr? Fix Supply can cross reference items and help you achieve substantial cost savings. We are highly competitive with all of the below products...

Don't know if this would be of interest to anybody, but last week I saw that Mitsubishi has added a new drive to their E800 series drives. It's a 120V single phase input to 240V three phase output drive, no need for a rotary phase converter. Because of the 120V single phase input this drive is...

I don't know about you guys, but I'm a little on the lazy side. Consequently my drill press basically ran at the same speed, no matter what I was drilling. It didn't matter whether it was a 2" hole in hardwood with a Forestener bit, or a 1/8" hole in steel - same speed. Over the weekend I...

I know a couple of other people on this forum use Designspark too, it's not just me. I think my anti-virus software changed something and I'm no longer getting the normal start screen with the latest news from headquarters when I fire up Designspark, but that's not the problem. I went on-line...

One of the projects that I am doing with here at work involves some of the equipment in one of our maintenance machine shops. We have an Optimum Optiturn D330 lathe that the nameplate claims is 230/460V 3 phase. We also have an Optimum Mill TMM200B, also nameplate rated at 230/460V 3 phase...

Being a COMPLETE newbie to FreeCad, I have somehow managed to turn my navigation cube inside out. It sure looks inside out anyway. I thought I had just somehow greyed it out, but I discovered last night that if I move the nav cube to just the right position, it looks like there's text on the...

Every once in a while my obsession takes over, and I just have to scratch the itch. This is it: Since I found this image in Smokstak I've been tying to find any more information about this truck/half-track/road locomotive. The article referenced in Smokstak was in the January 7, 1922 issue...

Over the past couple of weeks I've printed a few things that turned out to be mostly just for fun. This is one of them. This sad, and slightly blurry speciman is what's left of what was originally the cap for a salt and pepper shaker set. My wife and I had that set since we got married and...

About 20-25 years ago I made a pair of Shop Notes dust collector cyclones. I used an electric leaf blower for the DC fan. My calculations showed it was moving about 300-350 CFM. I made a prototype cylcone for my shop to see if it worked. I used the air filter from an '89 Aerostar as the...

"I have a clever plan milord", or maybe it's just a brain-fart - let's find out. A little background set up: Building a multi-cylinder glo-plug engine might be relatively easy(-ish), you can bolt multiple Cox .049's around a single shaft and get a radial of sorts. I've also seen several...

I'm converting Bruder Cross-country Jeeps to RC for Christmas presents this year, three of them plus the prototype - gotta make sure it works you know.. Part of this conversion involves modifying the existing wheels to be compatible with the N20 gearmotors that I'm using to get 4 wheel drive...

For the last couple of years I have been playing with the idea of designing a CNC router based on a Bosch Colt compact router, because I happen to already have the router. I wanted a CNC router that could handle wood, plywood, plastic - within reason, and MAYBE non-ferrous metals. I was...

Just sitting here thinking, which can be a dangerous activity at times... Would TIG brazing a copper boiler using silicon bronze rod be a viable method of assembling the boiler? Has anybody tried it? If so what were the results? Just wondering. Don

I'm posting this on several forums, so for some of you this might be a repeat. I've got a Monoprice printer that is actually a re-badged Wanhao D6. I managed to kill my printer last week, I static ZAPPED it - but that's not the only problem. As I was plugging in the SD card to load a new...

If additive machining, 3D printing, blunders count, then I've got one for your amusement. I was printing a replacement part for one of the R/C conversions I was working on, and the part was about 1/2mm too long. Went into the 3D CAD, shortened the part by 1/2mm, saved the file, and reprinted...

What are you guys using for a controller on your CNC's? The last CNC machine I built ran off TurboCNC so I'm looking to step up to something that's using technology that's at least in this century. I'm in the process of designing/building a CNC router and I'm not sure which way to go. I'm...

I got a Wild hair, Brain fart, idea the other day and decided to run with it for a while to see where it led. I was watching a video on YouTube, tutorial about how to build a wooden rubber band gun, and I started thinking I could 3D something like that. I started looking to see if anybody...

I was going to put this under the Packard/Merlin thread, but then thought it might be better as a new thread. One of the last posts in the Packard/Merlin thread mentioned that brand new Packard/Merlin parts were tossed into the scrap bin after VJ day. If you could time travel back to that...
