¿ªÔÆÌåÓýThose are ¡°last resort¡± fuses, you really want a resettable one like these: , or these: ? Replacing those fuses is a PITA, especially since they need to be crimped, not soldered.?

But shirts also had burn marks and paint.? So always had two shirts one for work and one for lunch meetings. I was on drafting board too.? Dave? gcvisalia@... 1:55pm? ? Yea, if and when I lube up a chuck I just cover the chuck with cardboard and then just step aside and spin it up. Stop and wait a bit and spin it up again. Pretty quickly I get nothing coming out. After that is cutting oil spray. But that's why we have bibs and such. And of course I never use clean clothes, they are all premarked |
Re: Lathe Front Shields
I had same shirt patterns?

My first two lathe where low speed 750 and 350 rpm so just spin at top rpm. .? My next was 1,800 rpm sound great to speed oil off the chuck now the ceiling and walls had a oil line too.? Dave? mike allen 1:39pm? ? Ya don't like that line in the shirt ? First time I took a chuck apart & cleaned it I used too much lube & ended up with that tell tail stripe o the front of my shirt when I fired the lathe up . I learned quick |

Re: Lathe Front Shields
It's pretty hard to avoid throwing some oil.? But if a lot of it is being thrown, too much is perhaps being used. When doing manual lathe work with a small low horsepower lathe, you only need a little oil IF you are using it for cutting.? If you are using too little, the cutting results will tell you and you can increase it a little.? And if oiling a chuck after cleaning, only enough is needed to make a film.? No need to flood the chuck internals with oil. Charles E. "Chuck" Kinzer

Re: Lathe Front Shields
Best proof of excellent functionality is how clean the lathe looks? ?? I'd be rid of both guards before plugging it in. On Sat, Apr 6, 2024 at 6:17?PM Craig Hopewell via <cch80124=[email protected]> wrote:

Re: Lathe Front Shields
I could not agree more , Charles.? ? The shields are an attempt to limit the "crunchy floor", and could well wear out their welcome.? ?For me, versus the floor, I try to remember to wear a face shield as I am visually impaired (retina disease) and have to work very close.? ?Often closer than the new shields.? ?The effort to make the shields was as much to see what I could build as anything of making a substantial improvement.
An infinitely adjustable cardboard square, chasing the swarf ejection, may be a superior solution, George. And now having said this, I have one of those coolant tube created shields with a magnet on the opposite end mounted on the drill press - with the shield positioned above the belt enclosure - not in use for years.? ?8^| -- Lone Tree, Colorado? ?USA |
Re: Lathe Front Shields
Most times I use a piece of cardboard held in my left hand. This is in part to the fact that I'm a paraplegic and therefore have to support myself with my left forearm on the control cover on the right side. Thus my hand is free to hold the cardboard. george
