    Will an oxy-acetylene (or other) torch melt this off clean?

    Grinders, die grinder with a burr or stione, cut off wheel, Dremel, combination of all of the above used gently. Torch would be too easy to mess up the locking ring. Physically or metallurgically. Plumber's type torch with a 1 lb propane or map-substitute probably doesn't have enough heat...

    Blue Thread locker "Loctite"

    Yes, it has an expiration date. Depending on storage conditions, it might or might not still be usable after that date. If in doubt, test it first or just throw it out and get a new bottle or tube of threadlock. BTW, not all threadlock compounds cure with all different metals. 'Active'...

    Mig Welder Acting Strange?

    Check contact tip, drive roll, drive tension, liner (blow out or replace), check all the torch to machine connections (both electrical and the gas seal o-rings). Small 4" diameter wire rolls ( 2 lb solid wire) can get iffy feeding when they are getting to the end but not all used up too. Have...

    Wood coffee table top varnish is worn off help

    That doesn't look like 'renew the finish', that looks like the finish is GONE in that section. Which means pretty much strip and sand down to clean bare wood, and then refinish at least the top. IMNSHO 🍺 Doesn't look like red oak either. White oak maybe, ash maybe, some other wood...

    Removing broken screws in mahogany

    Re: the screw install Find a STEEL screw of the exact same size as the brass, use that steel screw in a properly prepared predrilled hole, remove the steel starter screw, and then install the brass screw BY HAND (no power tool for the install of the brass screw). Also use a little bee's wax...

    Between 705 & 1200 SQ/FT My Mini Garagemahal

    OK, I looked a little more at your practice welds. Good that you realized that you should do some practice welds. 👍 Not bad. Could be better. How? Pretty much what Dr. Clyde mentioned. 👋 More amps on the machine setting and modulate with the pedal. More available amps, and move a...

    Century Old Flooring Question

    Good point Chuckster. The only spray foam that I know of that is fire resistant is the fire stop $$$$ spray foam. All of the others, RTFM as they usually require a fire resistant covering and can't be left 'exposed'.

    Century Old Flooring Question

    Laying new flooring on top of the existing pine flooring isn't going to do much to insulate the floor. The R value of 3/4" wood is about 1. Put a complete new layer of 3/4" wood flooring on top of your existing floor boards and you are up to maybe R value of 2. As well as making all the doors...

    Attaching girts to steel tube without drilling

    How is an olè going to help here? 🤣 Weld the panels to the posts, weld L brackets to the posts and screw or weld the panels to the brackets, riv-nuts in the posts and bolt the panels to the riv-nuts, etc. Or just use some screws to attach the panels to the posts. 😆 And put weep holes at...

    Need Advice On How To Strengthen & Reinforce Old Chicken Coop (Approximately 25' x 40')

    Oh, you need a new foundation, a new slab at least 8" thick of 5000 psi air-entrained concrete with #6 rebar grid, pier footings for the two post and four post lifts, all new i-beam posts and beams, new roof purlins, and a 4 zone HVAC system. Oh, and then the new metal roof. 😆 Slightly...

    Extractor kit to remove bolt with rounded off head

    Astro Pneumatic Flabk Bite sockets (and box end wrenches) work well within their limits. A shake-and-brake tool (Mayhew is one reputable company that makes them) on an impact hammer while you apply torque with a box or open end Wrench is another possibility. Or just a box end Wrench and the...

    4 1/2 angle grinder question

    A 30 year old angle grinder isn't necessarily better or worse than a new one. It all depends on the specific model grinders being compared. Amps (power) of the motor matter. A lot IMNSHO. ~4 amp motors can be bogged down with moderate pressure, depending on the attachment. ~8 amps motors...

    Made in USA rivnut tool

    Not made in the USA, but a USA company. Check out Astro Pneumatic. They have several hand operated rivnut tools, and some drill powered ones, and some Pneumatic ones too. Despite the company name, they do more than just pneumatic tools. They have a presence here on GJ too.

    Help me finally pull the trigger on a router

    Ah, the Norm Abram school of routers. 😆 Back in the day (waaaay Back in the day), Port-Cable 690 was the usual go-to general purpose router. Not any more, PC isn't the same PC anymore. Now, the Bosch 1617EVS is kind of the go-to. I have a Dewalt EVS kit with fixed and plunge bases...

    Using tempered hardboard for workbench top...

    Danish oil (or any oil finish) do not really have the same protection as film-forming varnishes like polyurethane varnish. And the old rule of thumb for oil finishes was once a day for a week, then once a week for a month, then once a month for a year. And you are worrying about waiting for...

    Matching 50+ year old dark trim

    Testing the stain beforehand, good.👍 Conditioner, pretty much necessary. What I really notice though is the grain mismatch. That's going to be harder to match 😕 If the stain 'color' is close but not quite dark enough, you can apply some stain (on the preconditioned wood!), let it sit a...

    Remove ALL of the old, cracked, or iffy weld. Clean the AR plate to bright clean shiny steel. Follow the hints and suggestions in the two links that I posted above about welding AR steel. Weld brackets/tabs to the AR plate. Use those brackets/tabs to bolt the plate to the cast iron post...
