Hi Jason, it was the oddest thing to see that on the table amongst all the other junk. Hundreds must have walked past. I did not know exactly what it was but instinct told me it was something special. Cheers
Good to see the trepanning tool in operation. I too dislike wasting stock which could be used for something else. The tapping head certainly saved a lot of time. Good find! Look forward to seeing the grinder in operation.
Not too long before the surface grinder is in action Clive. In fact I've done my first grinds but the videos are a bit behind. Generally I keep them to 20 minutes long if I can. Cheers
Paul, I am sorry that you’ve been under the weather - I’m 60 years old and know how that can take a bit to recover from. And despite that, you’ve put together another nice video that I enjoyed watching immensely. I hope you feel much better soon!! Know that I enjoy watching your videos as I sit and relax from a day of working in my own hobby shop. I was oh, so careful with my 1-2-3 blocks when I first started. Now (like you) I understand they are for the most part cheaply made and can be used for a variety of things. Cheers!!
HI Russell, mostly I never get ill but that one got me. My wife is always super concerned about hygiene and she gets all the colds. Me, well I'll eat stuff after it fell on the floor, eat food beyond its date, forget to wash my hands, and my immune system is usually 100% robust. When I say to my wife "I'm having salad shall I put some out for you" she says firmly "No Thanks!". Cheers.
A lot of hard work. Coming along well, but as you said, so many operations take longer than desired. I hate when I get a birds nest. My bench grinder came with balancing rings on the wheels. This design is a circular groove and two curved nuts which are moved around to get the wheel balanced. Dave.
Hi Dave yes I think the better bench grinders come with those sliding weights on the wheel carriers. My cheap bench grinders try to shake themselves apart, I should probably do something with them. Cheers
Yes, David Wilkes showed very impressed trepanning on very exotic, read blooming tough materials to machine, Inconel for example is tough as old boots. I thought he had sold his company and retired, but not sure? Ref our new government, i was most successful to see UK markets responded positively 🤔🧐 Excellent work, and addition to the shop, get better soon.
Hi John, David defo liquidated his company and then worked as an employee for a bit but left a comment on my video making the trepanning tool saying something like "if I ever get better" so that's what flagged a concern to me. Re the new Government (dangerous subject alert!) I like a number of their policies but what they actually achieve time will tell. Building 1.5m dwellings in max 5 years, even with planning reform, is a big ask. We'll have to nearly double the current rate of building, and that's best case if building ramps up immediately without any delay. Cheers Paul
Hi Paul. So interesting to see your home made trepanning at work. A definite swarf saver. Your tapping head sure paid its way for you. Such a time saver. Love the design of the adjustable wheel balancing ring. Very clever. Looking forward to seeing it in use. 👏👏👍😀
Hi Andrew, in many cases annular cutters would be better but for a very deep hole the trepanning tool comes into its own. That tool can cut a slug 60mm diameter and 200mm long, if you can cut from both ends of the workpiece (swap ends in the chuck). Cheers
Very nice work you’ve overcome all the little hiccups. I did enjoy your last video on the medical politics. Let’s call it may not be that may not be an app description but I did enjoy the video nevertheless, looking forward to part two of this video. A great day.
Hiya Kimber, it is kinda medical politics really because all this public services stuff is kicked about in the press and Parliament whereas if it was pure commercial then the model is just much simpler. But our new Government has a slogan "country first, party second" so we'll see how long that lasts. If they can work to that, regardless who we vote for, I think we will all be very pleased. Cheers mate.
Hi Paul, what a find that balancing rig was, a steal at 15 pounds I think. Enjoyed seeing your trepanning tool being used, I haven't seen that video can you include a link or just the name. What I like about the UK general elections is that power changes quickly to the new party, even if the result is hung. Down here it takes months and worse when the controlling party doesn't have a majority. We wrote to my Mums outgoing MP, Penny Mourdant, to thank her for helping us with the LPA. I really don't think doing something like this would be possible here so all is not lost up there!! I'm guessing that this one was before your extension building project as you sounded better in them. Hope you're making a full recovery. Have a great weekend!!
... and that video was made over and extended period of time, 4 or 5 weeks, due to the bad cold but also the work on the Haxby Shed annexe and a week away fell in between. Cheers
Some nice turning - I appreciate you letting the video run on and showing the facing and so on. That trepanning tool is great. I hope you are feeling better!
Hi Stuart, the trepanning tool was just an experiment to see if I could make one and indeed it worked surprisingly well. It's actually better on steel because those inserts have no rake. Flood cooling through the tool looks impressive with long ribbons of steel just shooting back along the scrap channels. I'm fit now but it took about 4 weeks. Cheers Paul
The 1 2 3 blocks can have things bolted to them with M10 fixings. They are designed to be bolted together with M8 studding that can also be used through the M10 tapped holes.
Hi Paul,, interesting project. I'm now 77 and still playing catchup on my 'to-do' list! I would appreciate a bit more in depth background on the theory of the balancing, the difference between static and dynamic particularly please. I am guessing static is only a starting point? Very nice engineering, kudos.
Hi Seapy, you saw me do a static balance there. If the rotating body was long like a crank shaft it could be in static balance but if the static balance was achieved by opposing weight displaced along the shaft it would start a rocking motion as it spun up. A dynamic balancer has weight sensors (transducers) on the bearing point at each end and checks for changes in bearing load as the crank turns through 360 (indicating a rocking motion). The dynamic effect is small if the rotating shaft is short and/or the centre of mass is thin because the rocking moment/forces are limited. The further from the rotating axis the more the effect of the weight. The grinding wheel is only 1/2 inch wide so I imagine that the dynamic moment would (only) come from variations in thickness of the wheel. I don't have any way to dynamically balance but you can make quite simple jigs actually (refer to RUclips), or buy an expensive machine. I hope that all makes sense. Cheers
I just ignore the threads in 123 blocks. Make some cross pins about 3/4 to 7/8" long at the smallest block hole diameter that have a threaded cross hole in the middle (1/4-20 here in the States, maybe 6mm for you) and you can construct any thing you want with some standard screws and the blocks. Add some larger fender washers on the heads if the screw heads are too small.
Hiya, thanks yes I'll have to explore how best to use the blocks. They are so cheap, in the limit I could even sacrifice one or two by adapting them for a specific job. Cheers
Yes Matt, in a later video because I still had to make a mount for the diamond and dress the wheel before balancing. It took 2 x 6mm grub screws (in adjacent holes) to get the balance. Cheers
David sold up his business and did for a little time some work for the chap who bought most of his lathe's. From what I've seen he emigrated to Thailand.
Hi John, when I posted the trepanning tool vids I got a comment from David saying something like "I may make some more videos if I ever get better" - for all I know he may just have had a bad cold but it did not sound like that. I hope wherever he is he's ok. Cheers
I dont know anything about anything but on the few surface grinders i've been around (2) they were always balanced by drilling out little divots of material on the wheel itself. This is clearly nicer but im too lazy for that :-)
Hi Josh, yes I have seen RUclips videos with owners drilling little divots in the stone to balance the whole assembly (wheel and carrier). I just feel this is a bit neater but I'm sure the divot drilling is fine too. Cheers
Politics, coming from poly, meaning many, and ticks, vlood suckers. Glad you are feeling better, and that balance wheel is looking good, a little polish and your wheel will be nearly perfect balance wise as well, though it will never be able to be changed without a rebalance, and you probably will be grinding off bits of grubscrew rather than putting in mass. once static you will probably still need a dynamic balance, so will move the length the screws project , or just get 2 different length grubscrews and use them as masspieces.
Hi Sean, thanks. I've found the wheel will roll on the balancing stand with just the slightest out of balance weight - just a few grams. It's surprising how sensitive it is. Cheers
Sorry to be a pain but in all the tool rooms I have worked in, nobody balances such small grinding wheels. They have such a small mass that any out of balance is so small that it causes no problems. I will add that the tapered arbor is never removed from the machine. When changing wheels the large thin nut is removed and the wheel changed. This protects the machine tapered spindle. The nut is either one with 3 equispaced weights permanently locked or a simple threaded disc with 2 holes for a pin spanner. Once a wheel of that size is dressed any out of balance will not show on the workpiece. Remember the wheel spends most of it's life smaller than when new so any out of balance becomes negligible anyway. Nice job so far on the ring but important for viewers to know it is not essential.
Hi Tates11, you may well be right that it is not necessary to balance a small wheel like that but it gave me a nice little project. 😁 You will see in later vid that, after dressing, it took a couple of 6mm grub screws to achieve static balance. The spindle on that machine is not tapered, the stone carrier slides onto a plan shaft and is clamped with a LH threaded nut. Cheers Paul
@@HaxbyShed The stone carrier 'with the parallel bore in your case' will usually be left on the machine spindle with just the L/H disc nut removed. As you say the wheel still has to be dressed unbalanced before balancing. Perhaps the out of balance was caused by the two countersunk screws, perhaps 3 would be the minimum to keep things relatively balanced. How thick is the wall of the balancing ring? it seems that there is a lot of wheel that can't now be used at the center.
@@tates11 Maybe. If the useful diameter of the wheel is reduced (some of the face taken up by the balancer) I'm ok with that. I am only a light user so that one stone might see me out. Cheers
Hiya, they are definitely CHICOM because I bought them direct from AliExpress. Experience will tell whether I need the holes - it was kinda "better get some of these because everyone else has them". 😁
A very interesting video. This seems to be the year for minor colds & covid, with most people getting ill. Me included & I am 78. Regarding the change in Government, we live in a Kingdom that has a parliament of the people for the people. So we must expect it to change. We do not want a dictatorship. (It is not a true democracy, France has a true democracy & look at the mess that has brought upon it since its revolution).
Hi Mervyn, I've come to a similar conclusion that imperfect democracy is the best system. Human nature being what it is and the inclination to fight, thankfully people generally accept the outcome of a transparent public vote even if they strongly disagree with the outcome themselves. Cheers
You bought a balancing jig for £15!!! You should have gone out and bought a lottery ticket on the same day! Looking at the price of them, I had to build my own. Thats when I found out how smooth ground drill rod isn't! I've a set of those 123 blocks too. Those "clearance" holes are annoying, aren't they.
Hi, I never thought about the 'flatness' of the smooth polished rods but now you say it I can see because even the slightest out of balance, just a few grams, will cause the wheel to roll on those 'rod-ways'. Cheers
Hi Paul, it's the thing we all want moan about but should not talk about. But then we feel repressed and when the right trigger comes all the bottled up stuff just blurts out at once. Remember the joke about the cork, the pig's bottom and the money? Cheers
Very wise to avoid political comment. Those Cobalt drills look like a Chinese import, are they solid Cobalt? UK drills also supply Cobalt, any comments on sourcing such? We are tending to use Cobalt exclusively and thinking of going single source.
Perhaps we should have a vote on it 🤣🤣. Generally I will "stick to my knitting" (i.e. the channel topic). I just occasionally throw in a considered line about what's topical here. HS has viewers all over the World. Cheers
@@HaxbyShed Might I suggest that things like brexit can provoke really strong reactions! Just imagine, something that doesn't really affect you much, but the person that signed up for your shed practices, finds you talking about something that they are very affected by and have been really unjustly treated, something that was a decisions based on lies and corruption!
Some nice machining work there Paul, by the way, £15 for the wheel balance was an absolute bargain, well done!
