Hi All,

I understand that some S7 rhs bearings have dowels which are tapped 2BA, for the insertion of a puller. HTH

Weird looking. Why the huge tubular spacers?

For those who don't know, I believe PCB material is very abrasive and requires use of carbide drills.

Hi Quenton,

I note your comment about your Sharp mill. I also have one. Great little machine but shame about limitations;

"Daylight" above table, which is not much when using a Clarkson windmill chuck.

Table only 4 1/2" wide. (Just continue struggling to workaround)

Only 2 T slots in table. ( I get by with difficulty)

I am interested to know how you increased the head height? I have given this much thought and have a scheme which is in with the rest of my "Roundtoits." My idea was to use 2 whopping great blocks of cast iron with a pair of holes in each. They would fit on the (retracted) overarm and the arm supporting the vertical spindle would fit in the top hole. About 4"/100mm increased height. Is this what you did?

Thread: Is Model Engineering in Decline

I am a Brighton club member, a thriving club. We have a member so young (11 or 12) that a condition of his membership is to be accompanied by a parent. There are a further 7 of various ages below 18. On the other hand, one member keeps reminding everyone that he will be 90 next year.

Worthing club, of which I am also a long standing member, has no under 18s that I am aware of. This being inspite of running council sponsored model making courses for the school ages during the summer hols. Hopefully, the memory will stick and some will take up the hobby in later years, perhaps when the hormones recede!

If the above is typical the most other clubs will either have no youngsters or several, but it's a start. This sort of discussion has been going on for years and will no doubt continue.

Thread: Anyone know about buying freehold to a house in the north

Hi Ian,

Agree with Andy, grab the opportunity which will give you full control over the property. Means that you can get repairs carried out at a price chosen by you, not exorbitant maintenance charges. Also alterations to suit you but maybe subject to planning law.

Great chance for your future. Sorry, cannot advise on the cost quoted but if it was me, I'd be inclined to take up the offer

Very good luck,

John

Dont blame you, that price seems so ridiculous that one could assume it's a pricing error. Let em keep it for ornamentation in the shop! Ha,ha.

Thread: Roundtoits
13/10/2019 16:32:12

I have answered the Club newsletter Editor's request for 'filler' to help keep it going by trying to write something for each issue. So far so good. Discovered the side effect is that it keeps me on my toes finding a subject for the next issue but at least those roundtoits are getting finished off so I can write about them and perhaps add a photo or 2. So far, most subjects have embraced my take on making accessories for the mill or lathe. Things like how I made an led ring light to fit above the vert. mill chuck to give shadow free illumination. Ketan supplied 3 axis DRO about 7 years ago, soon have it fitted and working! Currently working on 2 different styles of work stops for the mill vice. As I have more than one, I'm doing types that attach to the table rather than the vice(s). Another idea is to do a full article on a numeral stamping jig for machinery dials using a simple design that doesn't involve too much time to make and is flexible enough to suit diff. dias. and widths of ring. Have already made and used such jig but experience suggests a number of improvements. Am looking forward to getting article in mag.

Thread: Plinth size?
13/10/2019 16:05:10

I am not very clever with this sort of thing but a cereal packet cardboard mockup of what you think might fill the bill, always helps decisions. If I were doing this, I would start by making the plate first as suggested above, then arrange it in a pleasing position, then set about making the cardboard test piece allowing at least an inch, perhaps one and a half inches front and rear of fuselage, hull or whatever the model is and see what that looks like. Trim some off or sellotape a bit more card on til I was happy with it. Similarly with the other 2 sides, adjusting sizes until I was happy with the whole arrangement. Next, find piece of wood to replace cardboard. If its light coloured, a damn good sanding and a couple of coats of good varnish on the wood and the metal plate to prevent tarnishing. Maybe use 2 or 3 thinner pieces of wood of slightly different footprint glued together creating a stepped effect would enhance the appearance of the plinth. Have you thought about a glass or perspex case for dust exclusion? Good luck with project and give us a piccy or 2 of results.

Thread: diameter calculation

I prefer Nick's answer. Why 3 diff?

Thread: Metrication of models
07/10/2019 14:29:06

"Utter drivel" What a damn insult. When car sizes are quoted in umpteen thousands of mm, that is the rubbish /abuse of metric. How the hell can that be visualised? Only fit for comparing relative sizes of diff. makes and models, nothing else, like will it fit my garage?

Maybe more sensible to quote boards as 2.4m or go up to 2.5m, but not pig- headedly use 2400mm. Since when were they quoted as 96"?

At school we were subjected to that awful chant system of learning that 10mm = 1cm, 10cm =1 decimetre and so on but it was all a waste of time. We might as well have just been told about all the other divisions and their names and leave it at that. They don't seem to be in every day use.

To get back to strictly on topic, it would seem best to leave all the published designs alone, complete with their myriad errors and start afresh with new designs only in pure metric, not a bastardised metric conversion of Imperial measurements.

I have seen, e.g., somewhere on the Internet, a list of errors with Sweat Pea design and I understand other designs have received similar treatment. Just imagine re-hashing the design into metric and rounding the results to look nicer. Think of all the new errors that could arise.

Always blowdown to try and get rid of muck inside then leave bd valve open til next steam up. Do it every time and it will become a habit to (a) blowdown regularly and (b)close bd b4 filling for a steam up.

Last week saw a 5"G loco blown down over a bucket. Hell of a lot of what looked just like horticultural silver sand left in bucket, maybe 2/3 dessert spoons sort of quantity, far too much to leave in there solidifying on top of the foundation ring, the lowest point.

Thread: Metrication of models
06/10/2019 11:49:09

Anthony,

This is the stupidity, 8ft long board easily visualised but if "they" go and "metricate" that to 2,400mm or even worse, 2,440 or 2,450, that would be awful. Just like the 19ft new car quoted as being 57,912mm long! I would like to see my restricted to less than 1m, then go on to use say 1.4m or 2.9m or whatever, applicable to all industries, "no ifs, no buts."

06/10/2019 11:38:45

Bandersnatch, I do know better, put it down to tiredness error,

but,

I now know you read it!

Seriously, what a hideous system of value measurement. I think it was because so many everyday items had such a low price, e.g., loaf of bread one old penny. Blame inflation for making system look so outdated. Remember one of my secondary school teachers saying that this age would go down in history as the age of change just for the sake of it. He did appear to be nearing the end of his career. I find it amazing how quickly I adapted to the then new decimal currency but still see, say 1.5mm and automatically try to convert it to 60 thou as an approximate equivalent to be able to visualise that size. Soooo annoying.

Lease EU and revert back to Imperial? I hope not. We will probably become more aligned with USA for trade, using Imp for some types of business and metric to trade with the rest of the world. Just wish Parliament would obey a referendum result instead of keep trying to kick it around til they lose it. What's the point of having one if MPs want to ignore it? Get it sorted, move on and complete the metrication process which has also gone off at half- cock. Let's have some real progress and leave us old codgers to continue playing about with BA and BSF! Sod it, I'm  tired, it's late, cat out on nightly prowl and I'm off to bed.
