Tony, if you cant find someone to do the job before winter, rely on the fact you have CH. Ok, it might not be the cheapest way of heating your boat but so what. You won't die.

You'll need a beast of a drill to use a 6" hole saw and arms like the Hulk. I'd go for jigsaw.

Never having done this before my method would be: 1. Talk out of my stinkhole as usual. 2. Find someone who know about cutting holes in steel. Bank robber? Oh wait, its 4mm mild steel. Yep, its stinkhole time. Cutting torch indeed. 3. More bullshit yadda yadda FTFY So you're saying Maffi doesn't know what he's talking about? I am of the opinion that my advice to Tony C is valid - and it was advice to him, not to you. I generally seem to get by in life with my methods, we seem to have most issues under control, we have no debts/loans, things we make seem to last and not fall down, we have 7 years boating behind us and haven't come to grief.... what am I doing wrong??!!

Thanks Jim, once I've got settled I'll see if I get hold a winch for emergencies. With the holesaw I think the thing is probably to get a really good bit, and I think I remember someone saying keep the surface lubricated when cutting. I saw a youtuve vid with an allegedly pro installer who used the jigsaw method to make the hole, but I'll try a hole saw first I think. Just got the first load of gear loaded aboard today (not long got back home), and going to empty out my current place tomorrow, give it a clean, get rid of some more stuff at the local tip, and then head down tomorrow afternoon to get the final load aboard. It nearly did for me lugging a berlingo's worth of gear from the car park to the bank and down into the boat, took about 15 trips as I couldnt overload going down the steep bank side- I'm ashamed to say I haven't done that much manual work in ten years. At the moment its a mass of bags and boxes, some of which have gotten mixed up, and it will be even worse tomorrow when the second load goes in, but once I've got everything sorted (which will take most of Sunday), I'll stick up some photos. This is a quick look at the mooring- the Ouse-goers might recognise it. Lovely spot, but I have to be offski in a couple of days. imgur.com/gallery/IigtvpNAnyway off to bed now, I'm effing shagged out! Apologies in advance if I dont get many replies in for a day or two I think we had one of those circular hole saws and jigsaw..used them on the van conversion..the round hole saw was a right faff. in novice hands. We've used the jigsaw loads... I'm sure someone has mentioned but I must admit Ive nor studied every post..check the boat safety cert regs ref stoves before u have a go.

I cut the hole for my chimney with a jigsaw, one blade, no probs EXCEPT the built-in handrail prevented the jigsaw from completing its full arc so I had to resort to the drill-and-file method for about a sixth of the hole which was also easy if a little time-consuming.
Tony, consider that all working boats had the stove on the port-side (without exception). There is a reason for this, can you think what it is?
All stoves in narrowboats are better in the middle of the boat. I realise this may not be possible in your nice pro-fitted tub (however this would also mean that the radiator in the bedroom would be closer to the fire).

I've drilled a few holes in steel with hole saws, it aint easy!
A pilot drill hole is essential, better to get a hole saw that includes a pilot drill if possible.
Avoid the temptation to run the drill too fast with little pressure on it, you'll ruin the hole saw. Much better to put as much downward pressure on it as possible, it helps to be strong, and run the drill as slowly as possible.
Plenty of lubrication helps.
As you approach getting through the steel you WILL jam the drill in the hole. Not once, or twice, but several times. Don't worry about it, simply back it off either with the drill or if that doesn't work, manually, and try again. You'll get through eventually. As you're about to break through too much downward pressure guarantees the drill will jam. At this stage, and this stage only, run the drill faster with minimal downward pressure. The back of your arms and shoulders will feel like hell a couple of days later.

Depends on the drill actually. I have one that would cut through concrete with no issue at all.

Apologies in advance if I dont get many replies in for a day or two Ah, yes, I forgot about the cutting lubricant. I have a tin of it, lasts forever at the rate I use it, drilling, tapping etc steel. If it was just for the one hole I might be tempted just to use engine oil. naughtyfox will sell you some hardly used oil cheap. (Good morning Mister Fox, sorry to disturb you. Is that counted as bullying btw? I'm just helping you cover the cost of the tanker of new oil)

I did get one 177mm (7 inch) hole in 6mm steel with the holesaw but it took a long time as I did it slowly. Touch and go type of thing rather than continuous pressure.
Makita 14.4v NiMh drill.
The brush holders did smoke a bit.
The rest of the 5 holes I started with the holesaw to get an initial groove then drilled one hole on the line and used jigsaw to follow the groove. Easier than following a pencil line.
That was for internally mounted opening portholes so being exactly round was important.

Slow is indeed the way so variable speed counts for a lot. Lubrication, as many will testify, also helps (any oil will do). But so does torque. I bought this on a whim - £40.00 on sale. Take the drill chuck off and its also a breaker.

Take the drill chuck off and its also a breaker. I got something similar from B&Q years back, also £40 on sale, still going strong. Have to be careful when getting through a brick with the hammer drill setting, it tends to smash out the last bit. What I would like is the opposite of the sds fitting drill chuck, an sds chuck to fit in an ordinary drill, for the small sds bits. Never seen one.
