Thread: Suggestions please.

Hi Steve, yes I did read it in the first place, but as these threads progress one sometimes forget what has been said already. Having said that, reading it again it seems to be trying to establish the scanner errors and composating it into the calculations, whereas my thoughts were to be accepting any scanner errors into the final conclusions. I think thats what I mean.
 
Apoligies if I've got it wrong.
 
Regards Nick.

Hi, with this question of distortions while scanning, you may be able to scan you rulers set by your two rollers, to the same settings that you have scanned your cutter at, you could then print this off on to a piece of overhead projector film and overlay it onto the print out of your cutter. Any distortions should be the same in both print outs. Of course you will have to be able to have two rulers or whatever else you may be able to use, that will lay flat on the scanner. This may be achieved by carefully cutting a suitable piece of card or the like to your ruler settings with a knife.
 
Just a thought.
 
Regards Nick.
Thread: Best approch for securing a brass bush
01/04/2011 20:47:08
Hi gentlemen, first of all thanks for the advice regarding the best method for securing my bush.
 
Following Steve and Clive's advice, I decided to loctite the bush in. I kind of combined both your suggestions with my own idea as well, in that I made the bush to a push fit, but then releaved the end that would align with the 8mm long projection to a close slide fit. and the section that fell in line with the two holed fixing flange I knurled lightly with fine striaght pattern wheels, this made it about a thou and a half in that area bigger than the bore. It was then cleaned with loctite spray cleaner and 638 was applyed at the projection end of the bearing bore and on the knurled part of the bush. The bush was then pushed in on my fly press and went in with what I consider a nice feel and no fractures occured. It was then left to cure for a couple of hours or so and was then bored out to fit the newly turned part of the worm. A couple of grooves were then cut into the bore to help distrubute lubricant along with a couple of grooves long ways. (See pic below)
 

Clive, I considered an oil hole, but when it is assembled there would be no practical way of useing it, but I did disc cut a small groove across the face where oil could be squirted towards that area and some would find its way in (hopefully)
 
Graham, In the first picture it shows the end away from the the worm flange and the proportions are a little deceaving, the above picture shows the end that it fits up to and there is a thrust washer inbetween and covers virtualy all the area that can be seen, but suprisingly there is no wear in the end float that could not be tolerated.
 
This winch spent all its life out in all weathers with an 18Kw submersable dewatering pump hanging on it for many years untill it was condemmed by the insurance company for its condition and the fact the load rating sticker was missing. As it was scraped, a few pretty please words to my department head secured it for me as long as I removed it from the works forthwith. Its been kicking about in my garage several years waiting to be fixed, and will now be an attachment for my rebuilt car trailer.
 
Once again thanks for all your advice.
 
Regards Nick.

Hi, below is a picture of a worm from a hand operated winch. The front journal and its bearing were worn and corroded to a sloppy fit, so I've turned down the journal to reach good metal and to be round and the bearing likewise. A piece of scrap hard brass has been preped for a bush.
 
Now while in the past when working at my old employment I have fitted many brass bushes of sizes in the range of 2" to 6" in steel with a 100 ton press at my dsposal, I haven't really had to make and tackle anything this small and delicate. The bearing is made of cast iron and the bore is now appox 22mm and about 22mm long, the round projection is about 8mm high with a wall thickness of 4mm, and the journal on the worm is now approx 18.5mm.
 
My question is what would be the best way of securing the brass bush in the bearing? Would it be wise to try and make it a press fit and if so what size over the bore should I aim for?
 
The other methods may be Loctite or silver soldering. The main thing is, I do not want to bust the bearing casting.
 
Any suggestions are welcome.
 

Thanks in advance.
 
Regards Nick.
Thread: The boat that Guy built
30/03/2011 20:17:14
Hi, just watched tonights edition, brought back memories of when I was on the narrow boat holiday that I've metioned before, when they went through Harecastle Tunnel, only we went through the other way. Interesting bit about silk weaving. and a nice bit of picture painting by that pro boat painting lady, Guy's efforts of copying her were probaly better than mine. Strange he didn't know about the special bridge for the horses in the old days, I recognised what it was straight away and we don't even have such cannals in this area.

Hi Peter, it seems to be an information artical for the full sze engine, no suggestion of a model.

P.S. apparently there were three four stroke engines bult in 1927/28.

Hi John, below is an extract from L.B.S.C. on his Olympiade notes from 1938.
 

The coupling rods on this 2 1/2 engine are 7/32 x 1/8.
Hope this will give you some idea.

Thread: Things we should not do
27/03/2011 20:35:00
Posted by Andrew Johnston on 27/03/2011 12:35:16:
Do not wear gloves when operating machinery - if it gets caught, it'll drag your hand in.
 
Do wear gloves when welding - they protect against burns.
 
Regards,
 
Andrew
 
 
I'll second the piont about welding gloves, and add this includes ultra-violet burns (sunburn) for those that don't realise that any form of arc welding produces both hot metal and radiation burns.
 
In fact all parts of your body should be covered while doing any kind of arc welding.
 
Regards Nick.

Hi, one thing I'll say about files, wether useing them in the lathe or in a normal manner, is that, if it is designed to have a handle fitted, then it should never be used without one, and a good quality undamaged one with a decent ferrule should be choosen. The injury that can be caused to your wrist and arm from the file tang, from any type of filing action, just dosen't bear thinking about.

Hi mgj, your analogy with the cavalry reminds me of my first teenage years. I'm 3 of 6 siblings, when I was coming up to being 13 we moved house from a quiteish area to an area where there were a lot more youngsters of our ages. We slowly got to know our new "friends?" but being still kids we used to squabble amoungst ourselves and take sides when out playing, and of course some of our new found friends would butt in and started aggressive abuse to one side or other. Well that was it! how dare they talk to our brothers/sisters like that. So we were then banded together again to fend of these outsiders picking on our own kin. Once they were seen off on thier way we then resorted back to our own squabbling where we were interupted.
 
Needless to say the 5 of us who still survive don't squabble like we did when we were kids, but do have some differences of opinion about various things, but are adult enough to accept it and voice our opinions in an acceptable manner without trying to be king of the hill. But still won't tolerate others throwing abuse to any of us, we band together like a cavalry to fend off any unacceptable aggresion.
 
Regards Nick.

Hi, well if someone gave a bad or dangerous advice on here, I dare say there would be enough postings to correct that advice to the persons giving it and to those it was given to.
 
I does not matter how "perfect" or now correct we may think we are, in the end we will all be exactly on the same level. We are all only here for a brief time and we will all get recycled one way or another, no matter what you believe.
 
For someone who will never needs advice, may never be asked to give it. I could go on but that would involve politics, which I don't wish to do on here.
 
Regards Nick.
24/03/2011 08:26:05
Hi, IMO, any method of producing what you set out to achieve is correct. Donald I personally find your suggested F word on here offensive and belitting to those you are aiming it at. If you think thier advise is unsatisfactory, then I think you should say in a more constructive and adult way. Those who you consider are giving bad advise will not learn a better way with your type of attitude. I may well follow Kwil's lead and put you in the ignore member list that I haven't got yet, if you contiue you holyer than thou approch.

Just been watching the latest episode and Guy's attempt at tinsmithing, had to switch it off, I was beginning to feel quite ill.

Yeah, the baked bean thing wasn't good - but you should have kept watching, because he appeared to make quite a good job of the cutlery (and the forks and spoons)...

 
 
Hi, I just call them fighting irons, a term my late brother taught me when we were kids. Don't understand them posh words.
 
Guy's irons did look the part, and they did get passed by the QA lady.

Hi Donald, you have probally found one way of not being very popular anyway. Like Jason says, the home workshop rarely has the budget of a commercial outfit.
 
I've worked in industry for over 40 years and have learned that there is always more than one way of doing almost any job, wether it is machining, welding, fabricating, fitting ect. and even in industry budgets won't allow you to do things the ideal way always.

Thread: Tony Jeffree's Grinder letter in MEW175
21/03/2011 11:22:02
Hi, I can't speak for Terry's comment about the Emperor's New Clothes, but I think I understand it. As far as the letter goes, I believe I can associate it with things that I have never got round to finish, but that does not include a Quorn, Stent, Kennet or Worden or any other cutter/grinder for that matter, and not even in connection with Model Engineering.
 
As we are human we have failings, and we can find things complicated and a chore to set up, so go for an easer way. This does not make the more complex thing inferior, as a lot of people will excel with them, because while we are all fudementally the same, we are also all unique.
 
Tony,
in your first installment of your current artical in MEW 174, I'm afraid I lost interest in it when in the second paragraph you were on about the paint job, and started babaling on about DIY stores and the politics about scanners and self service tills ect., I have my own views on these and don't need to read about them in a construction artical. No offence but I think you should have just said basically what paint you decided apon.
 
Regards Nick.

Thread: The boat that Guy built
20/03/2011 20:25:21
Hi, switched TV on early this evening to sort through all my full RW DVD's so I could record the Wonders of the Universe which is on later.

When I'd done that, Guy and his boat he bulit (allegedly) was on, so I watched it. I reckon the clock man started mearsuring for the length of screws he would need for his new bit, but found out it held it OK with the mike. But seriously it looked like quite an old and basic mike and probaly held better than a commercially made clamp, and was probally cheaper from a second hand shop (where else) and of course he could preset it to fit closely over the two thicknesses of brass and clamp it up with one hand.
 
The thing I couldn't believe is Guy thinking that cotton came from sheep, I mean where has he been all his life, hasn't he heard the Beach Boys song Cottonfields?
 
His clock alarm was a bit OTT but it seem to work a treat with the window wiper motor.
 
Regards Nick.

Hi Norman,
The Anderton Boat Lift that you mention is something else that they could have spent more time on. If you are ever in the area of the Aderton Boat Lift (Northwich Cheshire.) it is worth a visit. Here is the link to their website.
 
Les.
 
 
Hi Les, I believe I saw that in 1979 when on a narrow boat holiday with my ex wife, who was just my girlfriend then. We were with my cousin and his girlfriend and my cousins sister (who was also my cousin). We had started off at Penkridge near Wolverhampton and went via Newcastle-under-Lyme, passed Sandbatch and Middlewich on the Trent and Mersey cannal and then passed the boat lift to get onto the Shropshire Union cannel somehow, to get back to Penkridge, can't remember to much detail about the route, as my cousin was navigator, and I was the driver most of the time, my other cousin was cook and the girlfriends had the job of opening the lock gates.
 
From what I remember of it, it was out of use and looked a bit rusty and negleted. Of course we only saw the top part of the lift from our point of view.
 
Yes I agree, a little more time there could have been interesting. I haven't watched this weeks dissapointing installement, might look it up on iplayer if I find time.
 
Regards Nick.
