Thread: Dehumidfier in shed would it help?
06/01/2012 17:42:39
The starting point should be draught exclusion. Not just stuffing newspaper in the mouseholes but a continuous plastic sheet across the wall with taped joint to the sheet across the ceiling and so on. If you must have an opening window get plastic doubleglazing unit - they seal like a kilner jar. Then the door - same treatment.
Even one 1/4 inch hole will allow a full air change in a few hours so you would just be dehumidifying the world if you have draughts and likewise insulation is defeated if the hot air just goes out of a hole.
Thread: Storage of machine tools

Perhaps one of the advertisers flashing away on the right of this page will consider making Ensis available in sensible sizes. There might be a problem with mail order but maybe we could all be walking out of Sandown next year with a can.

An earlier post
http://www.model-engineer.co.uk/forums/postings.asp?th=29735

pointed out that small ie hoby quantities of Ensis were hard to get. Any update on that?
I use diluted Waxoyle type clear car underbody wax on some things. I also let a jar of it evaporate a bit and use the resulting paste on a rag.
 
BTW never store under plastic as it sweats. Use cotton sheets (decorators floor cloths if not available from the house) as they breathe and provide more insulation for the microclimate.
A bit off topic but If you ever have to store outside under a tarp tent still use the cloth as it catches the drips and mist. Also outside never rely on those new woven plastic tarps for the tent as they are only waterproof while they are still in their sales pack. Use heavy builders plastic sheet to provide the water barrier then use the woven tarp just to provide a UV barrier to stop the plastic deteriorating.
Thread: Yet Another Tangential Tool Holder

Thanks, Chris. Have another glass on me
Thread: Hobbymat lathe leveling
01/01/2012 13:51:55
You only need a bolt if you feel it is going to slide off the table owing to vibration. Levelling if you need to can still be done with shims under the corners. Alternatively you could place it on 3 small raisers which will allow the bed to take its natural shape like a 3 legged stool. Then to twist the bed just put a jack under one of the rear corners.
Thread: Yet Another Tangential Tool Holder
01/01/2012 12:50:53
Having read around the links provided I have missed one aspect - what is the suggested grinding angle for general use? I think I saw 30 degrees mentioned but not explicitly as the grinding angle. One could presumably do the other end at a lower angle for brass.
Also what is the angle to grind the sides for a screwcutting tool at 55 & 60 degrees?
The Brunel tool would seem to provide a method for getting corner radii by making a silver steel tool with an appropriate head. However can a maths gemius suggest a formula for head dia /tilt angle/desired radius.
 
Thread: Turning very thin bar

Small diameters are everyday requirements in horology. Do a search on Jacot Tool but as some results are a little misleading here is one link: http://www.davewestclocks.co.uk/making_a_jacot_tool.htm
Some versions are just holes in a plate rather than dimples.
In use you would make a starter section close to the chuck to support in the tool.
Thread: What use is a washer
29/12/2011 19:33:42
As well as the multiply serrated washers for fairly obviously locking the screw head by digging in there are the single split washers for the same job and finally the slightly wavey washers for this purpose. I could never believe the last would work adding only a little tension in the bolt but lots of important bits in aircraft rely on it so it must be effective.
Then there are the washers used to take up and adjust end float for shafts and bearings or electric motors or on cars axles, or soft alloy ones with a fold over tab to lock the nuts on Landrover wheel bearings which with a hex nut gives you six goes and it still is impossible to get right.
Electric motors with plain bearings often have an interesting array of washers including a hardened one to bear against the bronze bearing, then perhaps a graphite filled mesh one to provide I assume an alternative thrust bearing of lower friction and then filler tufnol ones and finally the adjusting shims.
So does anyone know a supplier of these more unusual ones?
Thread: NEW MAGAZINE FOR MODEL ENGINEERS
29/12/2011 16:23:58
If the website gets enough interest he knows whether to risk actually printing something, and if he can collect advance subs then that might pay for some real articles. If he goes the way of some ebay etc ripoff sites that sell you a book but just send you a pdf that costs them peanuts then it can be easy money with only a thousand people taken in.
 
Anyone remember back in the pre computer '80s a major publisher churned out a 6 issue per year ME mag by literally cut and pasting photocopies from a few old mags that I assume they had bought the rights for? They didn't even have the decency to retype the copy.
 
Some big publishers punt new mags all the time based on a months printing investment. After all mags are their business like chocolates are to Nestles. Only if they can sell the advertising the mag survives. Readers are only important because they have to have some to justify the advertising rates. Exhibitions are the same if you do it right. The trade stands cover all the actual costs and the door takings are profit and funding the admin to get the next year's show off the ground.
 
eek, I've only just joined the forum so probably just here to sell something

Interesting to see mention of Rachman. A few months ago I had reason to mention his name and nobody in my audience had heard of him. Realised I was the oldest in the group and the term Rachmanism has left the modern vocabulary.
Anyway back on topic whenever I see a new mag started up I think of the strain on the trade who are lumbered with another advertising bill in a market that has not grown but has in fact had thousands of pounds diverted from their ptoential customers into the magazine's subscription.

Thread: Blackgates power hacksaw drawings
25/12/2011 17:42:55
Neat idea Ady. I think I might make one using an alternative nut to the tension wingnut from square with a ballbearing in it then I still have a proper handle.
 
I recall there is a lathe powered design which has a support frame pivoted on a bearing on a morse taper to go in the headstock. Then a crank goes on the protruding end of the shaft and the link rod goes rearward to an extension of the blade frame to keep it all compact.
Thread: Types of metal

If you have a real live fire, stove or open, you might find a few days in the hearth will soften them up, but some might just get harder. If it melts into a shiney pool it was alloy
Thread: metel supermarket takeover

Sounds like it could be useful for bits bigger than the modelling outlets usually stock.
Has anyone used the London one?
Thread: Engine 1000, or other Yarrow like designs - has there ever been a model?
18/12/2011 02:11:06
I think there has been a 3 1/2 version displayed a few times on the North London Club stand at the Ally Pally show. I don't know whether it has a yarrow boiler but I recall it is an excellent quality model.
Thread: Number Drill Sets & Ba Tap sets
17/12/2011 12:52:29
I endorse the comments about imperial sets being a wast of money nowadays, for Europeans anyway. It is easy to become a tool collector rather than a modeller.
 
I suggest a block of wood drilled with lines of holes for each tap size with holes for tapping and clearance drills. Saves making mistake because you thought you had learned the tapping size and didn't look it up. Then only fill it as needed. Later on when you have all the ones you really need but want to satisfy the collector instinct allow yourself to purchase one size at each exhibition you go to.
