mini mill

Great machines are not necessarily the best machines, but machines that reach the greatest audience. In this regard, one can say that the Atlas lathes were some of the most successful machines of all times. If I remember correctly, over half million were produced between the late 30s and the...

Was walking around in Florence (Italy) last weekend and came across a glasses store with a mini mill in actual use. Hope you will indulge me with this non-machinery photo, too: Anyways the store was closed so I couldn't ask what machine it was. Does anyone know?

Is it practical to counterbore cast iron or hardened steel cylinder head valve seats with a mini mill? If not, what would be the least expensive new or used machine that could handle 16 valve seats per week on a routine basis? Exhaust 1.757" x .315" Intake 2.068" x .315" The cutter heads look...

Hello everyone! I just got a Littlemachineshop 3990 mini mill and it's awesome. I haven't actually checked the tram of the column yet, but I figure I'm going to have to tram it with shims. I know these little mills suffer from less rigidity than larger machines, so I'm wondering if I should...

Hi everyone this is my first post here I'm supposed to get my LMS 3990 soon. I ordered the heavy metal CNC conversion kit. Having used the mini mill in the past there are some things that I want to address. Firstly there's the rigidity of the column, even though its a solid column there is...

I recently got a Harbor Freight Mini Mill (branded Speedway, but it looks like a Sieg X2D) fairly cheaply at a resale shop that cleans out houses and estates. There were several items missing that I needed to purchase to get it back to operating condition. That done, I used it to make some...

Hi everybody, I bought a groove assembly with two 47.6mm diameter and 6mm height tungsten carbide tipped discs (see picture). The discs have no key nor screw that prevents them from spinning w.r.t the arbor, only a nut at the end. The assembly is mounted on a 400W mini mill with manual feed...

I am a pharmacist by trade and have never used a milling machine before. I decided to buy this mill mostly to help slot guards for my knife making hobby and for some other projects I have planned like crossbow parts and sterling engines. I know it's been done before, but I'd like show a bit of...

Greetings all! First time here... not actually a machinist, but a knife maker. I need to be able to cut brass (only) that's no thicker than 1/4", 1/8th " wide slot, 1/2 to 3/4" long. This is for making finger guards on knives where the blade goes into the handle. Traditionally, I have done...
