    Recommend a wood finish for me

    Test the finish on some scrap pieces of the wood type/species before using it on the actual items. Just to evaluate how it looks and applies and behaves on the specific wood(s). And the usual reminder about oil finishes and spontaneous combustion. Safety matters! My dad once used some oil...

    Pressure Washer Pump Protector - Anyone Use It?

    I use some after every use, since I don't know when the next use will be. Lubes the pump somewhat, displaces residual water somewhat, and adds some freeze protection. Squirt some in until it comes out of the output hose connection of the pump (high pressure hose disconnected from the pump and...

    Dynasty 400 vs Invertig 251

    You have the sufficient electrical service available to run that beast? Single phase 230V needs a 70 amp circuit and minimum 8 AWG supply conductors per the manual. 3 phase is just a little less. 1/2" thick workpieces are going to usually require multiple passes no matter what. Root...

    Recommend a wood finish for me

    "Tung oil", not "tongue oil". 😆 What do you want the finish to do? Change the color of the items, or not change the color? Some finishes will change the color of wood items to some extent, even without using any sort of wood stain. How much 'protection' do you want the finish to offer...

    Jigsaw or sabre saw

    It runs, so even though I hated it I couldn't quite just throw it out. Keep it for some really rough job that might come up someday that I don't want to use the nice Bosch for. At least that's my story. 😆 The Bosch is a REALLY nice jigsaw. Smooth running, variable speed, controllable...

    Jigsaw or sabre saw

    Jigsaw. Uses jigsaw blades. Blades are available in two mounting forms, older style U shank blades and newer style T shank blades. Grips the blade from one end and reciprocates that blade up and down perpendicular to the grip handle. It is a handheld tool. I have an old orange B&D jigsaw...

    Case hardening process

    More cook time does increase the case depth, up to a certain point. Clean the part, coat/immerse it, cook it, quench it. Good luck. 👍

    Case hardening process

    If a file skates on the part surface and doesn't dig in, then the part surface is harder than the file (most likely). The center punch leaving an impression/depression/mark is because you 'overwhelmed' the surface hardness (you applied a concentrated surface compressive stess higher than the...

    Selecting a Framer Nailgun

    Nope, not what I said or meant. I said that a couple dollars difference in price is really not going to sway me as to what angle of nailer I'd pick. Pick the tool for the task. Looking at all of the tool and nail trade offs, size and weight (including loaded up with max nails), cost, power...

    Selecting a Framer Nailgun

    Paper collated nails seem too delicate and water sensitive to me. Wire collated nails spit and leave the wire pieces. Plastic collated nails don't have the water issue of paper collated nails or the wire nubbins of the wire collated nails. They do spit the plastic pieces though. Eye...

    Selecting a Framer Nailgun

    The 'best' framing nailer is often considered the Hitachi (now Metabo HPT) NR83 or NR90 (newer, lighter, more powerful, can use max 3.5" nails compared to 3.25" max nails for the NR83). Both are pneumatic 21° nailers, so you'll need a compressor and air hoses. If you will be using 8d or...

    Case hardening process

    Mostly covered by others, but I'll chime in anyway. 😁 A36 is low carbon steel and it does not have enough carbon in it to harden via quenching. Case hardening is where you heat a piece of typically low(er) carbon steel in a carbon-rich environment for a relatively long period of time...

    Is this cast fitting weldable easy ?

    Absolutely agree. If the motor and pump can support 275 gpm, then the rest of the system (piping, fittings, reservoir, etc) MUST be able to support at LEAST 275 gpm. You don't want your pump to cavitate and destroy itself because your suction line couldn't support what the pump needed...

    Is this cast fitting weldable easy ?

    OK. Malleable iron fitting are generally considered NOT Weldable for most cases. Because the heat of welding changes the iron structure from Malleable to brittle. Which means it will likely crack, sooner or later. Some limited exceptions for non-structural, non-critical, non-pressurized...

    Is this cast fitting weldable easy ?

    Couple of things. That 'fitting' at Target is for the steam-punk/industrial decor look for things like shelves and brackets and such. They LOOK like pipe fittings but they usually aren't RATED as actual pipe fittings. Beware. Next, 275 gpm through 3" nominal pipe. Eek. Your flow...

    Draw Burnishing Tool

    Knotted wire wheel on an angle grinder removes most paint and rust without chewing through the steel underneath IMHE. Not necessarily all paint or all of the paint or rust, but usually at least a good portion. Crimped wire wheels don't do much though, at least for heavy duty tasks. Neither...

    Demolish staircase

    First floor ~8ft above the basement floor means you should be using a 12+ ft ladder. Ladder is supposed to extend a MINIMUM of 3 ft above where you are climbing to to allow for gripping the rails and stepping out onto where you are going.

    Shop Vac - Ridgid or Dewalt - Portable Unit

    Dewalt stealthsonic vacs are impressively quiet, yet still **** in a good way. Quiet enough that hearing protection is not absolutely necessary.

    Broken Bolt Extraction - Welding on a Nut

    I have never failed to extract the broken bolt/screw/stud from the hole it broke in when I've welded a nut to the remains. Crossing my fingers that I didn't just jinx myself. Sometimes it has taken multiple welding attempts of the nut to the remains, but the process has always eventually...
