Valery. And if in a day of hire such a hammer drill or a crown breaks in your hands? Here, purely by accident, it will take and break. Is such a case provided for in an agreement with those who provide an expensive tool for only 15 bucks a day? xaxa

150 mm is the diameter of the hole? Under the chimney?))) If it's clean - then just use the paid services, or rent a tool. Because such a diamond crown itself stands like a small private helicopter, and is placed only on a hammer drill with SDS max, which costs like a helicopter of the same kind.))))
I drilled a lot of holes in an ordinary household drill with a thin motor (12 mm) with an outboard motor, and then, setting a peak on it, knocked out this "sieve" ... But then I need to "cultivate" ...
And then I found out that renting a large punch with a crown for a day costs $ 15 ... And was it worth it to suffer?))))

Don’t listen to anyone. Do homemade things further. Just some will not understand that the process of making such a homemade product itself brings joy. Not everything in this life is measured by money and time.

It has been said more than once, is it better to go behind the drill for X kilometers? Despite the fact that you need 2 holes, and in the future, only the great-grandchildren will need a drill? I understand that you are lazy to make a couple of body movements. It’s easier to buy for 200 r and rent gasoline for 200 r

what are you arguing about? This is about a summer residence, where, only grocery stores. I came across 200 km from the city, plus early morning, or evening when the household was closed. I made a vise from the channel, and sawed large keys onto the water from the channel, because the gas key has wide lips and overlaps what needs to be unscrewed. etc., it is clear that in urban conditions this is nonsense

So I wrote that it’s only advisable for those who have a “deployed base” for all this ... If I have trimmings of the corner, trimmings of the fittings, a welding machine and several grinders are standing nearby - why don't I spend 20 minutes and not done ???)))
And, if, for example, I have everything else, but, there was no suitable corner, then I will go and buy .... no! Not a corner! ... A rake! )))) ...
..A "sofas" I do not call those who buy a rake and drill, but those who vehemently deny that in principle it is not possible to make them, because they themselves do not even allow for a moment the conditions that I described ..
For them, this is some kind of mysticism! ... Well, how can you have at hand the whole instrument, and even the material? !!! After all, they go to the store even if you need to buy two screws! ... And then the corners ... fittings ... pipe ...))))

Literally today I encountered a similar reaction of the "divan troops"
It seems that everyone has their own opinion on expediency. I live in a city apartment, within walking distance (5 - 7 minutes of unhurried walking) 3 shops of tools and fasteners, at quite affordable (for my pocket) prices. Well, I won’t do drills and rakes, I’m better lying on the couch! yahoo

and for starters to the receivers.

In our country, it is the receivers first of all that the state supervision is very “wooly” ... I somehow collected (a long time ago) all iron garbage, hired a car and took it to ferrous metal. And there they were just checking ... I was immediately pinned to the wall, on the subject, "Where did the physical person get some industrial mechanisms from?" (And there was only a thing, the old towing truck for pallets .. More precisely, its remains). And the man was standing nearby, who brought a telephone box ... To the question "where" he, like I could only say "Lying in the country" ...)))). And, even though such booths were only in the USSR, but ... "they were not sold to the population!" ...)))
I left (there were no problems about the cart when they realized that it was ... Although they looked askance, like (but where did you take pallets at home?).And he remained to write an explanatory note, where he got it.

No ... We don’t have such a "lawlessness," thank God ... At all, cast-iron dachas and bathtubs are for everyone to irrigate, and after all, not everyone has fences ... But they don’t steal yet ...
The school is nearby, also not a single hatch.

And this is how ??? With us, if one hatch, and not in a very crowded place, will be ajar, and at the same time not fenced around the perimeter with stakes with a taut red-white ribbon, this is an occasion for someone from a high-ranking road worker to lose his job. And if someone else manages to fall into it - this is a real prison sentence.

And nobody will accept whole hatches, not only will they be confiscated, but they will also be fined and the office may be covered. And the cops have no complaints about broken lines. So I heard that somewhere in the cemeteries the color. Metal is stolen (before the boards, "bumps" were made of duralumin, it was easier and cheaper to get it than marble or granite), and so we don’t have it - they won’t find the cops for that and unscrew the head, and to begin with the receivers.

If you wish, you can pass. Smash, chop and pass. Nearby neighbors hung a hatch about 2 months ago. Good all cameras like Christmas trees hung. The thieves did not have the brains to raise their heads and see if there are cameras or not? -))))) The school is nearby, there is not a single hatch.

Literally today I came across a similar reaction of the "couch troops" ...
I have a YouTube channel, and today, under a video about home-made pen drills, they wrote to me that they said, “what’s not necessary for this blast furnace”? etc.
I mean, since there is a welding-grinder, then buy and drill ...
Dear "sofas" ... For that matter, all my drills will not fit in several buckets ...)))). But, nevertheless, sometimes it’s easier to do in 15 minutes than to postpone the work !!! Because the right drill may not be HERE and NOW !!! Or, for example, I somehow needed to drill through two adjacent beams of 200 mm each. The hole needed 18 mm. Many of you have a half-meter-long drill-eighteen ???? ... Or do you suggest you don’t decide in 15 minutes, but thoughtfully search tomorrow for such a snap ???)))))
So what? If I need 15 minutes to solve such a "problem", and you need a day, then WHO ARE THE FOOL ???? ))))

And another “pronounced sofa master” wrote me something like: “Your advice is useless! I live in an apartment. I need to drill 5 holes in plywood. Where will I get a grinder and pieces of iron ???” ...
I replied to him that only a schoolchild could not do such a thing, from which dad hides the instrument ... Since any man has ordinary feather drills ... But if he doesn’t, he goes and buys ... Time doesn’t press him, but the tool will not be superfluous ...

Well, not because of savings, drills are done !!! And FOR TIME SAVING!

I saw my acquaintances - behind the garage ... (Nobody will steal them anymore))))
Our legs will be fastened quickly, and will be turned into scrap metal.Well, if the pots and pans in the dachas were stolen during the winter (not aluminum), then God himself ordered the vice. Now even sewer manholes are made of some kind of heavy and durable plastic, the cast iron ones all stole, even in the middle of the road.

Valery, I wanted to write a detailed answer, yes you take everything literally, take offense yet,

Here - by!))) I don’t know how to take offense at all!))) ... I can give the person in the face (or get it!)))), And if the incident is over, I will give him my hand tomorrow and I will to joke over yesterday ... (Exaggerated example. In the face beat / received the last time ... well, a very long time!)))))) ...
But, nevertheless, seriously, I can’t understand the very essence of the phenomenon of how to “hold a grudge” ... If I’m wrong, “give me a muzzle”, and we will continue to be friends, if we recall what was - then only with a laugh! ...))))
to have a special vise for welding is an impermissible luxury for many simply because of a lack of space, almost everyone has a workshop with a 6x4 garage, and only one vise. I can indicate my reasons: firstly, I do not do welding work often, but those for which I need a vice, even less often. Secondly, there is simply nowhere to store individual vices.

Their role, as a rule, for all friends (and for me) is performed by "completely killed" vise, which is no longer a pity ... (In mine, for example, there is no one sponge))) Since I also have to very- cook in a vice very rarely (not every year))), then they are screwed directly on the street ... When welding, I always use clamps, and the "welding vice" is not to hand them in scrap!))) ... Sometimes they help ... )))

Valery, I wanted to write a detailed answer, but you take everything literally, take offense again, so briefly: I treat the “welding” vices as a necessary evil (like the “Blue Canary” used as a gas analyzer in mines), and not they mean, but ordinary workers. Regarding the number of vices, I can say: having a vise specifically for welding is an impermissible luxury for many simply because of a lack of space, almost all workshops have a 6x4 garage, and there are only one vise. I can indicate my reasons: firstly, I do not do welding work often, but those for which I need a vice, even less often. Secondly, there is simply nowhere to store individual vices.

Now I rarely use the tool at home (I live in an apartment), but after use, before laying out the cases, I always wipe it with a dry cloth. Somehow nicer when the instrument is stored clean. yes

That's what you all are right here !!! They count the money ... "It's more expensive than that" ...
And here, I also often make home-made feathers on wood ... Although there are a lot of them ... But ...
Here at a construction site it was necessary to drill ... But the right size is not at hand ... (He is. But you need to go after him) ...
So what??? Will you go after him and lose the whole full "working night" ??? (Indeed, today there will be no time left for anything - until you change clothes, while you go, until you change your clothes back ...)
Making a pen drill takes about 10-15 minutes ... This is if a large diameter is needed. If small - rivet the round timber, and grind it with a bark, adjusting the desired width, takes even less time ...))))
Pancake...Do you value your time ??? I used to buy a grinder, because in the evening I decided to go to work, and to go far for a grinder ...) I bought it on the road and it's ready ... There are no extra grinders - it will remain in the household)))).
And already a drill ... If on the way - of course I bought it and that's it !!! ... And if you are already "on the site" ??? And no one to send to the store? ...
Is it difficult to wave the grinder a couple of times, and twice with an electrode?))) And who will take into account how much this "drill for one hole" will cost ??? ... In any case, it will be cheaper than the time lost on a trip home , or to the store ...

So what??? A person who goes to the theater, even when loading the dung in the country, must be in polished shine boots?)))
You have a strange worldview ...
And I also have dirty shoes A vise charred by welding ... Because how to fool around with overlays ... Take off, set ... Let the pioneers in the circles do it ... But I am a practical person ... I need a result, but it takes time ... And I I’m not going to spend it on extra gestures to protect the vice from scale ... Moreover, FOR WHAT ??? So that in between what I need to cook, remove linings from them and admire ???)))) Anyway, the "welding" vice is a rough thing, and they won’t lose their functionality ... And I don’t care what my grip hurt someone’s eyes ... I do not interfere with the influx of welding on them !!! And besides welding, I don’t do anything in this vice ... For another job, I have others ...
... Or are you doing everything with just a vise ??? And weave a hundred-corner in them, and carry out the exact cuts by the grinder in the same vise ??? ...
Well, no ... I’m sure that if you are "friends with iron", you have three or four vices ... But a vise for welding is just a vise for welding ... And what's so bad that they are covered with scale ???
P.S. I didn’t minus if that ... Everyone has their own troubles ... I have a friend who wiped the puncher body with alcohol after concrete work, although it was planned to continue tomorrow ...

I'm just curious, those who "minus" think that using a vice like this is correct? I did not say that you can’t cook in a vice, I made it clear that this way the vice will be dirty with metal splashes. And so that this does not happen, those who take care of the instrument carefully make lining of the tin in the form of corners, which then it is not a pity to throw away. When I see a vise or anvil that has been electrically welded, I have an attitude towards their owner, like a man who came to the theater in dirty shoes.

Very helpful article. It turns out that instead of the “ballerina” you just need to have a locksmith, buy a welding machine, learn how to cook and that's it ..... you will have a hole.

Pen drills 200 rubles / 5 pieces are. A set of crowns for wood / plaster / tin is also not expensive. Welding covers the cost of the rest of the tool.

You are not quite right, you came from the position of a master who needs this tool all the time. Here, a solution is proposed for a summer resident, with a one-time use. The price of a feather drill is 32 mm. from about 100 rubles. plus the road to the store, gas or a ticket, plus time. Making a drill takes about 15 minutes ... I burned one quarter of the twigs rod, the price is 230 rubles kg. in a pack of about a hundred. In the video, the option of fixing the drill through the collet clamp is also deployed, this is one bolt for 8 ...
