    alternatives to flood coolant

    Yes I could, but I don't want the hassle of maintaining and ultimately disposing of and replacing flood coolant anymore. Thanks Joe

    alternatives to flood coolant

    And, it's your inspiration that lets me text message people with words like yer and gunna. Keeps them on their toes.

    alternatives to flood coolant

    My sentiments exactly. In this case, I'm pretty sure the hole is my fault, though. There are areas in the sump with exposed steel and there's no rust or corrosion, the E206 and conditions preserved the tanks quite well. Instead there's an irregularly shaped hole about 1/8" in diameter straight...

    alternatives to flood coolant

    I have a 20 year old Arrow 500 that I use maybe half a dozen times a year in my home workshop. I've had the same batch of Trim Sol E206 in the sumps for 8 years since I built my detached shop and moved the machine in. When I filled the sumps I put in a large aquarium air pump running one...

    tooling and strategy for carbon fiber?

    I have to machine a "plaque" out of 1/16" carbon fiber sheet for a friend, profiling the outside (a 16" x 5" ellipse) and some letters inside. I think the largest end mill I can use for the letters is 1/8". I suspect that multiflute is the way to go, more like machining titanium than aluminum...

    create a trace (lines, splines, and arcs) from a region in a bitmap graphics file

    I agreed to help a friend out who is re-living his adolescence by building a musclecar. To replace some cobbed together piece of crap trim created by the last guy to work on his ram-air hood, I suggested a badge cut from carbon fiber sheet. The outside is an ellipse (easy enough) and now I have...

    Comments from Phase Perfect owners

    The oputput voltage is the same as the source. The US standard is 115V/230V, not 110V/220V. Any equipment made for the US market should be built to operate 230V nominal, not 220V. 208V, well, that's a whole 'nother thing entirely that requires a transformer (not that 230V is not stepped down...

    Comments from Phase Perfect owners

    I found an air filter at Home Depot that fits right in the opening in the bottom of the DPC-10. Once, the unit tripped when I was energizing the servos on my Cinci Arrow 500. I removed and reapplied input power and all was well. Other than that it's just been peace of mind knowing I'm feeding...

    what end mill and who makes it

    I have a MariTool reduced shank 3 fluter showing up tomorrow. 3/8" dia 3 flute 3/4" flute length .354 solid shank. It will be hanging out of a TG100 collet about 2.75". Not sure where to start with speeds & feeds. Well, I'm limited to 6000 RPM so that's a done deal. GWizard gives me .0021 CPT...

    what end mill and who makes it

    I hardly see where my title was bad... I wanted to know what end mill to use and who makes it, thus the title. Joe

    what end mill and who makes it

    Brian, Thanks for the link but they only make that style in ball end mills. Sca, I don't have the quantity to justify a custom tool. Utry, thanks for the nudge, that's probably where I saw them before. Got one on order, in ZrN. Joe

    what end mill and who makes it

    I have to pocket out some 7075 aluminum. The pocket is 1.25" deep but is next to a wall, making total stickout of the tool 2.7", but the pocket wall is not flush with the adjacent wall, so in theory I could use a 1/2" or 5/8" shank down to the top of the pocket, where I am limited to 3/8"...

    3D Space Navigator Opinions Please ??

    I have a Pilot (HP branded) I got off ebay used a while back for around 1/2 original price. I found it to be an improvement (and strangely intuitive) with Alibre. When rotating with the selector in Alibre, I often grabbed the wrong "handle" and the rotation would take a few tries to get right...

    do reamed holes in aluminum shrink? reamed hole coming in under size...

    A brand new sharp reamer cuts as close to size as it's going to get, and can even cut a little oversize. A machine reamer (NOT a hand expansion reamer) cuts with the chamfers on the leading edge of the flutes. The periphery of the flutes do not cut. As a reamer dulls, it will cut undersize as...

    Lead screw vs. ball screw

    Problem with ballscrews when manual machining is you have to lock the table whenever you take your hand off the handwheel. The table will run away very easily without the static friction that a conventional leadscrew adds. Joe

    Bacteria Growth

    Years ago when I worked full time as a machinist I used to cut myself all the time. We used Oakite MM. I would put a band-aid or piece of tape on it and go right back to work. I swore I healed faster immersing my fresh wound in the coolant and grime. If I tried that nowadays, with my health of...
