Are there any EDM services here on HMEM? I'm building Vederstein's Dancer engine and manage to break off a 1/8 drill bit about 1/2 inch into the hole for a steam transfer port in the engine block. You can see that one hole that's buggered up pretty good. Could I make another? Yeah, but I don't...

I could use some help. I've cut spur gears before but now I want to tackle bevel gears. If there are any threads on HMEM for this, please point me in the right direction. Any help will be appreciated so I don't end up with a box full of scrap bevel gears. Grasshopper

I've seen a Fractal Vise before. I would certainly love to have one. Aren't there times when you have that odd piece that takes a while to secure in a vice? Has anyone heard of plans to build one? The only ones I've seen are 3D printed plastic ones. I came across this fellow who makes engraving...

I was given a Fireball V90 CNC router setup. The young man allows me to use his online Easel drawing program. I'm learning as I've never used CNC before. But I'm getting there. I've drawn something in Easel and twice the fellow showed me how to put M2 at the end of the G code and I've lost how...

I was given a Fireball V90 CNC machine with a computer. Has anyone had any experience with this to machine material pertinent that we do on this site? Using common sense, what and how much can this unit machine? Thanks in advance. Grasshopper

I could use some advice on a set screw problem. I'm building a marine steam engine. When I put the eccentric valve assembly and tightening the set screw on the crankshaft (many times during the build to see movement) sometimes something binds a bit and the eccentric moves on the crank. This will...

I was given a block of aluminum for a project by a friend. I would like to get it to a mirror finish if there is a way. Don't know what kind of aluminum it is. I've tried a buffing wheel with the green high polish rouge and then tried my random orbital sander with 2,000 grit sandpaper, then...

Just wondering if others have this problem with iGaging products. In the photo I attached, the bottom DRO was purchased about 10 or 12 years ago. It's a 24 inch for my X axis on my Bridgeport Mill. Rarely any problems. The upper one was purchased in the last couple of years. That one is a 12...

I purchased a set of plans for a Model Marine Engine. As I was starting the project, I noticed something that helped me immensely. Whenever there was a inside radius corner to be milled, the designer put in the plans where to begin and stop the "center" of the end mill so the edges would be...

I finished Vederstein's 4 Square Engine. No, the colors don't mean anything, I just like how it looked. Ved makes really easy blueprints to follow. This is a Youtube video of the engine running: Grasshopper

I have always admired the craftsmanship of the members who make 4 stroke engines. They are beautiful. Can some of these 4 stroke designs be modified to run on compressed air? Or is that just wishful thinking? Grasshopper

I have a Brown & Sharpe/Micromaster Digital Micrometer, the one for $650.00 new. When I tried it recently, the numbers were faded in the window. Checked the battery and it was low. I ordered some new CR2032 batteries. When they arrived, I put in a new battery (the mic didn't have a battery in it...

Got Vederstein's Swashplate Engine finished. When I first finished the parts and assembled it (unpainted), it ran. Then I paint all the parts, reassemble it and no go??? Then figured it out. The paint on the underside of the swashplate was still rather soft and balled up and the steel balls on...

A woodworking friend of mine is getting an X-Carve CNC Machine. I asked him if it can do metal. He looked it up and said the manufacturer has indicated that the machine will do non-ferrous metal. Here is the items' website...

I want to build another Rudy Kouhoupt's 5 Cylinder Radial, only bigger. If I doubled the dimensions on everything, do you think I will run into unexpected problems? I'm an amateur machinist. I did build the smaller version of the 5 cylinder, but now want to build a bigger one. Grasshopper

I've come across so many blogs and threads where the machinists say they use Loctite (insert number here) for a particular assembly of their project. With so many Loctite products and numbers, are there any places where I can go to or download from with a concise explanation of what to use for a...

I normally don't charge friends or family to do something for them. However, a neighbor asked what I would charge their school to thread 24 rods with 3/8 - 24 threads at each end. And she will not let me do it for free. Any idea what I should charge? Grasshopper

When drilling a blind hole, you are obviously going to end up with the bottom having a 118 degree "funnel" at the bottom. I'm looking at suggestions to help me "square off" the bottom of the hole. I've tried using an end mill and my boring head but I'm not comfortable with either. Any...

Before I drive myself nuts, are there plans for a manual machinist to make chess pieces? I just made a chess board out of walnut and ash for a relative and would like to machine the chess pieces from aluminum and brass for him. I only have manual machines, mill and lathe. Thanks in advance for...

OK, I can't be the only one thinking about this. I'm throwing out an old computer. Take out the hard drive and destroy all your data by torch, bandsaw, sledge hammer of the disks. I take it all apart and the disks and drive bearing hubs are machined beyond my capability for true spinning. I see...
