Re: Patio's projects

Maybe just a simple NO micro switch. A roller tip model could be modified with a grooved roller like a pulley to avoid rubbing on the cable as it operates.

Re: OK, I've done it now, I got a welder

Sticking the wire usually occurs at lower amperages, particularly when using larger wire at the thin material end of it's range. But I've personally proven you can stick the wire just about any time at the end of a bead, particularly out of position. As mentioned, get good lights. I often work with ...

Re: What are these stones?

Looks to me like a hone, but not like any sunnen type hone I've seen (not that I know much). I've seen an automotive (in general) rigid cylinder hone with stones like those. They appear too big for one of the flapper cylinder hones, but again, that may just be my limited experience. http://www.engin...

Re: Looking for suggestions for a respirator

You want to really get worried about welding byproducts, read up on phosgene gas. That can make for a very bad day, and applies to all welding processes, particularly electric arc. Not even getting it completely dry before welding is safe. I'm no expert, but anecdotally it appears that even tiny amo...

Re: Ko lee surface grinder

On that same topic, I recently found a wide fork pallet jack in good condition used for cheap. VERY cheap, seems nobody wants an odd width pallet jack. But I've seen one modified to be wider used to move machines used by an amateure rigger who used to work around the area. I then used two pieces of ...

Re: Ko lee surface grinder

Do you have a pallet jack? For a while, I built several heavy "low boy" bases for some of my machines. But I couldn't or didn't want to put machines like my mill, lathe, and surface grinder on portable bases. Lately I've been building setups that will allow my pallet jack under the heavy item so tha...

Re: Info regarding lathe clutch repair

I don't know about your lathe clutch, but in the automotive world, what you describe is almost always a throwout bearing. The common initial characteristic is "noisy until you engage", but in many cases (full failure) it is also noisy engaged. So my first suspicion would be the same.

Re: Small File Cleaning

I would never use a file on another file. Maybe if I had a really stubborn "pin" to extract, just a targeted approach, but even then I would use a small pick or something, unless a needle file was all I had. But that would be a last resort. File cards get a lot of bad press, and I can see how they c...

Re: Hardening a gunbox

Agreed. The M17S is no longer available and brings considerably more than I have in mine. If I were to lose it, I would probably get a Mini-14 and add one of the nice bullpup kits. A friend of mine had a pretty trick little Mini-14 that also ran dependably. Then again, I haven't been in the market, ...

Re: Hardening a gunbox

IIRC, I got my M17S for $700 new in the (poly gun case) box from Bushmaster with (as I recall 3 magazines). I fixed the flaky feed problem, and added mounting rails (and accessories) while removing the fixed carry handle, added some cooling improvements, but other than that, it's pretty much stock. ...

Re: grinding a three jaw chuck

Even if the support is at the very back of the jaw, I would think it would be hard to get behind the scroll far enough that the force (vector) would tip back to make the jaw tip forward (clamp surface inward). I've used just such a nut-spider to load the master jaws for soft jaw boring, and from my ...

Re: grinding a three jaw chuck

Sorry but I am having a problem visualizing your hex nut spider, unless it is to be gripped inside the jaws. In that case how would one grind the jaw faces. Set the spider as deeply in the jaws as you can. With the screws near the front of the nut, and the whole resulting spider located at the very...
