I only ever use corded for the bigger stuff like soil pipes thro a double skin....even then it's sometimes a struggle if the bricks have been fired with added kryptonite!!!

I don't have corded power tools now after the Bosch knackered up and was replaced with the Milwaukee CHPX, which was a beast in comparison and never even hinted at struggling before so assume something is amiss, I have the M18 and M12 hammer drills too which also work well with standard masonry bits when you don't need such a big drill and great for drilling up to 10-12mm holes. I think I'll get the SDS serviced

Not sure fixed is the right term...the 1st cutter I bought on Amazon died. This is cutter no2 (eBay 2nd hand jobbie)...I decided to check the cable restraint. The white component is not attached to the cable so a good pull would detach the cable....not a very good design.
I'll probably use some amalgamating tape to help with restraint inside and outside until I can figure out a better approach.
Needed it on the outside too...it's like they glued the cable in but the glue failed leaving the cable free to pull out or twist!
There's no earth...and the head part is metal....I may have to look at it again to sort that out. There is a plastic separator so hopefully they got that right!

many years ago, when I built the garage, I ran Ethernet out to give me Wi-Fi out there. its been working fine til recently.
now it isn't.
I had to extend the wires because I was stupid and cut them too short, the connectors are waterproof but obviously it wasn't a good long term solution.
so i fixed it...
and in doing so gave myself a lot of work refinishing my toilet...
dug up the splice
pulled new wire through the conduit.
then up through the bathroom wall
replaced the plasterboard
and by the front door as i now had a offcut to use
and made up the joint in the loft. in a dry location and completely accessible jelly crimps are totally acceptable.
"conduit" replaced (its data, proper conduit is tiny, hard to pull through and expensive by comparison, this works... gimme a break
)
now it isn't.

Bitch of a job. Well done.
Looks like quite an impedance mismatch going on there!!
Network cables rely on a well defined twisted pair structure (by insulation type and thickenss, and twist pitch) to provide a characteristic 100 Ohm impedance, and immunity from crosstalk and interference. Both of those characteristics are compromised in the join that's visible in the images above. A better method of joining would be to terminate both ends of the cable with Ethernet jacks, and using an Ethernet joiner/coupler.

that link does not support your assertion.
dexgreen gel filled crimps are widely used for data connections. Using 2 RJ45 plugs and a coupler is a bad idea, in my opinion. But as The Dude says, that’s just, like, my opinion man.

indeed. i have made thousands of connections with jelly crimps, and like the link you posted states, if you connect it with a idc correctly (like with jelly crimps) it works fine..
bear in mind my day job is dealing with exactly this type of issue.
i fail to see how making multiple connections by crimping a plug on (the same type of connection ie idc) to then use a joiner (2 more resistive connections) then another plug, would not introduce MORE resistance than just 1 joint (again, using the same type of connection, one designed for exactly this application)
but hey, im only a telecoms engineer by trade, what do i know?

CAT 5/6 is pretty robust and will cope with a surprising amount of bodging. I've been part of a few design reviews where we had to run unmatched traces over short distances (relative to the 100m odd total length).
Nonetheless, voipio is right. IDC or not isn't the issue, along with cable resistance, solder joints or any of that. Ay higher frequencies, what matters is the capacitance and inductance, and the ratio between them. Simplifying, the inductance comes from the wire and the capacitance comes from the distance between the wires and the material between, in the wire itself and a proper connector this is designed to all be the same. Where it isn't, like jelly crimps and with random distance between the wires making up each pair, you'll get some of the signal reflected back rather than transmitted.
But, a lot of work has been done in the integrated circuits to make cat 5/6 robust to some very uncontrolled wiring, so cat 5 will almost certainly work and cat 6 probably will

Amidst a multitude of carb jobs I had the pleasure to work on this over last couple of days, a 12,000 mile service plus tyres and anything it needs just do it.
Not really a fan of the modern sports bikes but blooming heck this thing is an absolute beast, but surprisingly forgiving throttle response even in Race mode.
Quick Shift is absolutely seemless as well.
Think this is the 3rd Generation S1000RR and they keep getting better!.
Really well sorted road bike, was genuinely impressed.
