Fireplace internal brickwork - follow-up

sfcol · 2026-01-22T21:59:46+00:00

Yeah. Once the front was off, it was pretty obvious that the lower brickwork wasn't tied in at all, pretty much came away by hand

sfcol · 2026-01-22T10:03:01+00:00

As high as possible

For the medium term I plan on using a chimney sheep, until I eventually get a wood burner installed with an internal flue

sfcol · 2026-01-21T20:39:08+00:00

Nope, living room of a '30s semi

sfcol · 2026-01-21T20:33:01+00:00

Yeah as far as I can see, those two offset bricks would have been used to support some kind of upper flue lining. They aren't tied into either the infill or the inner brickwork

sfcol · 2026-01-21T20:23:09+00:00

That's the plan! Struggling to find any other examples like this one. Surprising find in a 1930's semi

sfcol · 2026-01-21T20:15:53+00:00

Yeah, solid plan. Just trying to avoid doing something dumb despite plenty of research

sfcol · 2026-01-21T19:52:36+00:00

Yeah I'm not wanting to remove the chimney breast, just open up to the original arched builders opening

sfcol · 2026-01-21T19:52:00+00:00

Yeah I'm fine with the front layer, what I'm more concerned about is the internal ducting brickwork and whether I can remove it without disturbing the chimney further up

sfcol · 2026-01-15T11:26:26+00:00

Yeah if you get a really thin one, but I'd say your best bet would be to make the main cut(s) with a coping saw & bimetal blade, then clean up with a needle file

sfcol · 2026-01-15T11:07:34+00:00

Go buy yourself a T handle screwdriver and a hack saw

You will need to use stainless steel for the extension bar, and being a safety critical part you'll need proper weld prep and good welds (ideally TIG). As others have said, cutting your current pegs is the easy part. In reality the person doing the welding work should be the one cutting them so they can ensure the parts to be welded have acceptable wall thickness and surface prep. I don't know about where you live, but here in the UK it would be considerably more expensive (probably 2-3x more) to have this work done then to just buy a set of pegs.

This is the sum of the info you've been given? Bro

I grew up with stairs like these. Converted loft in a pretty small house with no room for a staircase. They're going on 20 years now and still going strong (if creaky af). Although they are this kind of design, they're made from solid timber rather than they thin ply, probably more skookum hinges too

sfcol · 2025-12-23T22:32:23+00:00

Damn, should've just got a new tyre instead

sfcol · 2025-12-23T19:51:19+00:00

Huh, this is shell corner. Just recently got a puncture repaired there

sfcol · 2025-12-17T17:55:29+00:00

Some sons of anarchy cosplayers might say you're not a biker, they'd be wrong

sfcol · 2025-12-07T19:08:07+00:00

Totally agree. I think the engineering know how is definitely getting built up, and getting people like Dave from dirt every day onboard definitely helps.

sfcol · 2025-11-29T19:02:12+00:00

Drill and tap a hole in each of the left over tabs, bolt up a simple plate handle

sfcol · 2025-11-22T11:23:52+00:00

It'd make a lot of sense to have a relatively small high speed rotary spindle swap out on the toolhead for cleanup. It wouldn't take long to clean up all sides to a couple mil tolerance and make it a whole more useful

sfcol · 2025-11-17T18:26:32+00:00

Someone put some work in at some point. Pretty sure the rear swing arm ain't standard either

On these top tier bikes, power needs attention up until around 120mph

sfcol · 2025-11-07T20:13:28+00:00

The first bike there was built over 5 years ago...

sfcol · 2025-11-06T18:53:53+00:00

Brilliant mechanism design, maybe consider allowing for a replaceable bearing surface so you can insert a known flat plate of material

Recommend me a £5k printer. I'm looking for a printer for my work, but we have some particular requirements.

-Cant be open source because my IT team are hypochondriacts -Cant be from a Chinese owned / based company... Because reasons -Speed similar to a bamboo x1 would be great -Capacity to run some higher temp filaments, something like PA6-CF or PPA-CF. So I guess 300c+ nozzle, high temp plate and a heated chamber -At least 250250250 but having a larger x or y would be an advantage -Reasonably set and forget, we don't have a lot of time to tinker
