Notching and drilling joists

[kirkgas]

Or how about these ? They are for use in notches, not holes though. Pegler Yorkshire

The newer guidance for notching says to drill two holes as "corners" and cut two vertical lines down to meet the holes creating a "u" shape rather than rectangular, so these wouldn't fit, TBH if you are notching or drilling joists why do you need to clip them down they are supported at every joist, so a bit of lagging keeps the pipes quiet

I can see every heating squad in the country taking up that idea. They would need to invent a curved rip snorter blade :smile:

A router with a bull nose cutter does the same but faster and you can set depth.

Faster than i snorter? Can you run a room of checks as fast as you can walk with a router?

Keh?..?

Can you run a line of notches using a router faster than you can walk the length of the room twice (up and down). I doubt it? You can do that with a snorter (circular saw):yesnod:

No not faster than a circular saw (snorter) but faster than drilling through and cutting down. Which seems laborious.

This type of thread is exactly the reason I told my nipper to constantly view the forum.
Its the type of thing they don't teach you at college, and it's nice to see the variety of answers.
Keep it up guys.

I prefer to multitool 2 slots and then 3 hits with a mini sledge and a framing chisel. Accurate, goes through nails and is fairly satisfying. Imperial blades are pretty bombproof and can handle a fair few nails before they wimp out on ya.

circular saw, hammer and wood chisel all day long for me quick and easy!

Drop the wood chislel its not needed :wink:

Judging by the responses to this thread there are a lot of weakened joists about. Correct method is drill a hole and cut down to it. This minimises the damage to the joist and gives a neat finish. A good right angle drill and sharp bit make it easier. You can still use a rip snorter but set it the radius of the whole shallower. To get a nice straight line of holes set a batten for each line of cuts and run it through before drilling the holes.

There's loads of talk about cowboys on here but people are willing to smack hell out of joists with a hammer to save a few minutes and do the job properly.

I prefer to run surface mounted when possible to save damaging joists, was on a job where the backroom floor was basically a trampoline due to the notched joists

But when needed I battern and noggin the joists if there less than 7" joists and the jobs willing to pay

Hi just reading this thread, and tryin to find the op request.
My understanding?
Pipes need supporting?
So if the pipes run the same way as the joist, then support them.
If pipes are fed through holes in the joist, or are supported every 14inch or so by a joist, then why clip the pipes, to the joist?
Just lag the pipes?:tounge_smile:

Really?? Nothing about notching joists being hard work in 2015

when I was in collage they told us tat we could notch down to 1/8th of the joist, so if you have a 160mm joist you can notch 20mm out of it for example. and the correct way was to cut man slt in it with a wood saw or circular saw and then cut it out with a sharp wood chisel and mallet. to be honest I allways use a circular saw, I only cut as deep as I have too, but if you don't cut enough then floorboards creek when heating goes on etc. to whoever said on here that they batten and place noggins in joists.......... I think you are asking for trouble doing this after somebody has plastered the celling's , probably popped screw heads everywhere!! lol, and I cant see any customer willing to pay me to do this kind of job, and if im correct , noggins are only there to stop joist twisting ect, if you cut too much out of the joist its going to bounce no matter what you do,

I ment I nagging to support pipes after drilling holes in centre of joists
