    anti-seize but not anti-seize for salt road vehicles?

    I don't drive my Chev 1500 4wd much; but took it in to the shop for work on the driver side brakes. They replaced a bearing on the passenger side and said that was the problem. So, the next time i drove it, to bring back a small mill from an auction before the auto-shop visit, almost did not...

    30nmtb aux spindle?

    I put $5 bid on a #6 Whitney mill, partially rescraped by owner, local auction, missing drive. Missing horizontal spindle, but came with what looks like a BB grinding spindle in the top/overarm bore. Typical sopko grinding taper on the end. Useless to me. My interest is a small horizontal...

    "Best"? exhaust valve guide material?

    I'm trying to top a VW type 1 based 2276 av-conversion. The exhaust valves are stainless, supposedly Manley. According to the logs, the engine has less than 35 hrs on it, although it was "moteur neuf" in 2013. (could mean new, or could mean just "fresh") It is possible that the heads were...

    soda vs walnut shell blasting?

    I have a large (MC frame size) blast cabinet with garnet, an outdoor use pressure pot blaster, and a smaller cabinet with walnut shell. IOW, the practice & expectations are not totally alien to me. My question re: recent soda blast popularity - how does soda blasting compare to coarse walnut...

    Shaper: internal sawing

    Some may recall previous posts; back in preparation for "Y2K" i was asked (hired) to participate in making steel shutters and "gunports" for a local backyard fort. I did not have a coldsaw, and made a hacksaw for the shaper, to saw to repetitive length, and to saw miters and angles in...

    How do you use a hog oiler?

    OK, I understand the purpose. Having grown up in 4H things like sheep dips and other de-licing/anti pest treatments are not unfamiliar. But i can't picture how a hog oiler would be used` (applied) ?

    Handplanes: use, set up, preferences?

    I must be bored. Who is using them, how do you optimize yours. Someone linked me to a recent Paul Sellers Blog and asked for my opinion. I posted some rather innocuous responses including history, but he keeps taking them down. (there are a couple remaining to other's posts, but he took down...

    Anyone used 10 year old GF Endurovar?

    Still got a 5 gloss & a couple single gals of satin 2013 vintage General Finishes Enduro-Var. Stopped doing finishes almost that long ago, except for French polish and a couple rare exceptions with Duravar (totally separate mfg'r, solvent type finish). Need to use the GF product again and no...

    Stellite vs plywood?

    I sometimes make brazed tools (shaper wing cutters, e.g.) with stellite tips; so am familiar with the material and prefer using it (building tools with it) over carbide. But it occurred to me that i can't remember if i've used stellite on plywood edges. The "party line" from one source, which...

    retrofit: control voltage to 2 coils/motor starters simultaneously?

    I have an SCM TOP35 "32mm" gang drill with 2, 2.2KW (3HP) motors on the drill head. Being Italian, original electric controls are wonky, undersize, and have let the expensive smoke out a couple times in relatively few run hours over a dozen years. (can go years without use) The original...

    Anyone using heated (electric) sox/gloves/footpads?

    A few days ago i rode up the ski lift with a guy who said he was 83. He was really pleased with his electric gloves, but said the batteries were expensive, and proprietary. I have had Raynauds all my life, so the idea is appealing. When i started to research options, there are a bewildering...
