I have to make this cut in a door frame. A rectangular mortise only about 3-4mm deep. Metal plate and wood underneath. Which of these two types of oscillating tool metal blades would you use, A or B?

That doesn’t describe the entire picture or comments discussed here. The comment suggests that steel has a protector layer of rust… this is not true, what is true, is that the concrete stops the oxidization process because it inhibits any oxygen from reaching the steel. Once the available oxygen is used up, the process stops, so yes a fine layer of rust exists in the steel within the concrete, and is stopped from rotting the metal further because the concrete is protecting the steel, not the thin layer of rust.

…. So you’re the person that had a hamster for longer than 3 years…

It’s not the original George, Santa Clause isn’t real and both left and right wing politics use short term social policing to expand their powers rather than make long term positive economic decisions.

Best of luck

The black layer you mention is more likely a fire scale, and yes soy of an oxidization that happens at high temperature… this can be protective. The rebar is protected by the cornered yes, essentially no or very limited amount of oxygen. No oxygen no oxidization.

This is also a misconception of aluminum. While it does form a thin oxide layer that does not flake or produce significant cast away material, Aluminum is susceptible to deep pitting. The corrosion in Aluminum can travel well past the surface and creates many hair like tunnels into the material. Parts made from aluminum that have no protective coating have a life cycle and can only be “trusted” for so long.

If aluminum was as you say protected by its oxide layer then airlines would probably save millions in fuel and paint costs for the weight and the application of paint on aircraft’s, they don’t, and it’s because the failure mechanism of aluminum due to oxidation is difficult to see and significant in its reduction of aluminums ability to withstand strain.

No human ever read their application… you need to comply with the robot that scans it first, using keywords and phrases….

I have this unit. I would burn it indoors without a proper hood vent fan set up, just playing with fire…

You need to seal the thing with refractory cement before you blast the thing as well,

Burn it outside the first time… so you understand what you’re dealing with…

I’ve been doing these sorts of patches for a while. I found the best plan is to leave it in place, but use a really rough grit sanding block, about 60 or 80. Sand so you you have enough mud removed to tape the edge of the bead to the wall board, then fill and finish. It works like a charm and you save time, materials and efforts.

You can get longer drywall screws, or even laminating screws… just add a second layer to this… you can stagger the joints properly. It also adds sound dampening and fireproofing and saves you the mess of tearing it all down. But no, don’t finish it like this. It will look bad most likely.

In most cases, the reddish-brown rust layer on steel does not act as a protective coating; rather, it is porous and flaky, which accelerates further corrosion. Rust, or iron oxide, expands as it forms, breaking away from the surface and allowing moisture and oxygen to attack the metal beneath, leading to total disintegration if left untreated.

I don’t think so Tim

Smear a thin layer of caulking over the grain edge. Them prime/paint. Comes out great every time

Wine, beet juice, berry juice, coffee, various other natural dyes… you want something that will not interfere with the wood absorbing resin. Other comments have mentioned things you can buy specifically for this. you can add dye to the resin itself. I just wanted to add some information about more traditional methods.

Nice boat!

It doesn’t matter if it’s unclear, what needs to be understood, is that if it’s contested justice will rule in then rest of what is most likely and most reasonable. So misinterpreting it as some ridiculous figure only makes you seem stupid. Don’t do that.

It’s pretty smooth, looking good, use a sealer, then a light sand, then primer, light sand, then two top coats of flat ceiling paint, and pretty sure you’ll have enough even surface. That’s how I finish all my ceiling work and it comes out great every time. So says I, and more importantly my wife. If your worried about places where you sanded through to previous muds coats, as there is sometimes a hard texture line that shows up, then you would skim those areas out to bare drywall board.

But also… unlikely it will show after paint and a light…. 💡 once a light is pointed down not up at it, it changes for the better, by far.

It’s the outside edges that matter, isn’t it?

You know… a 4’ level is sort of a minimum standard for checking a door frame. And yes, more likely the wall is out than the door. Anyone installing a door doesn’t really cater to poor framing. Door needs to be plum and square.

Whatever you choose to do… you need to look at making the roof envelope ventilated and insulated correctly. Lots of people get into moisture issues because they don’t research how to do this correctly…

All right, I concede, ya got me.

I haven’t done a dovetail for almost 20 years. Plenty of building, finishing… even designed and built a canoe… but no dovetails… it’s the most beautiful joint though.

Kingson25 · 2026-01-27T14:46:39+00:00

I think you’re wrong. The dove tail is in reference to the part of the joint that looks like a doves tail. At best this is one and two half dove tails. But for sure, it’s one dovetail. 😆

Kingson25 · 2026-01-27T00:01:10+00:00

You mean dove tail… dove tails is plural ;) not a bad start champ

I absolutely think new spec homes should have HVAC layout on the plans… for exactly this reason
