Thread: Where's my Dykem blue gone - there's no need to read this
18/04/2019 07:52:49

It should be on the glues, paints, solvents and sticky tapes shelf, roughly in line with where that stream of hot swarf comes off the lathe...

Right, so what's the equivalent here?

You've set me up...
A murmuration of complainants

A murder of groans

A gaggle of grumblers

A batch of bodgers

A vineyard of whiners



Thread: shop vac at B&Q

I happened to notice these discounted (£100->£50) while there yesterday. No idea how good/bad and don't need a new one myself but a heads up...

PSI ? I dare not think what the metric equivalent is, let alone use it in any meaningful way. My boiler calcs are all in psi, lengths in inches and I grew up in a metric world. There is room for both....just dont tell the american space telescope makers!

Throw in a few atmospheres, pascals and bars then confuse yourself further with troy ounces, grains, drachms or a few old lengths of perches or fathoms or land v nautical leagues let alone hands and cubits. Spoilt for choice really.. they still use bushels and pecks too...

Thread: Hamerite or not?
02/04/2019 13:56:49

I've used the new formula smooth black hammerite and although it dried slowly I felt the finish and durabilty was quite good.

I you want durable.. I once had a floor done with basecoat, paint flakes, several layers of clear epoxy and two top coats of UV protectant epoxy - but anything can get scratched in time..

Thread: Soft Feel Finish on Radio

Ebay seems to be the place to buy chemicals these days and somehow the sellers get away with posting noxious stuff with limited packaging (at least the few I've bought). Acetone, isopropyl alochol both available.. and I just looked and ether sold too ..


Thread: LED replacement bulbs
30/03/2019 11:35:45

Dependng on the bulb size/shape finding ones with a decent wattage can be challenging. Finding them with both a decent price and with a meaningful warranty is even more challenging as is finding one's that last anywhere near the claimed lifespan.

Thread: Non-Drip Gloss Paint
30/03/2019 11:29:38

<< Can't think of any paint offhand that doesn't say shake or stir before use. >>

Many years ago i offered to paint a old lady's kitchen in the fashionable orange of the era. The tin clearly stated not to stir before use. I'd painted half of the walls before noticing the colour going from rich to faded. I too the tin back to the shop to be told I should have stirred before use followed by a surreal discussion before being given a new tin of the stuff (which I stirred, used and succeeded with).

As someone who hates painting most of my woodwork is stained or varnished. The very limited gloss stuff I find best to do with modern water-based low odour paints and small gloss rollers for all but the edges - all of which I mask off with low-tack tapes so I can slap the stuff on and get it done.- finish is excellent.


Thread: I want one!
21/03/2019 13:17:38

I used to have one of those industrial truncated cone spools of kevlar thread (from my bowstring making days). I went looking for it in the barn to be told by wife that she had seen a pair of rats, one at each end, squeaking intructions to each other as they co-ordinated rolling it out of the barn, through the cat flap and up into the woods. She was too fascinated to interrupt...
I'm still waiting to see the rats wearing cat-proof kevar vests ...


Thread: Cap head screws
21/03/2019 11:51:52

Like everything else it depends on intended usage but for my messing about I usually buy stainless capheads from ebay. I have a whole selection of sizes and lengths from my r/c heli days as a staring point and top up + extras in the sizes I need. Obviously for high tensile situations (which rarely apply to me ) I use that type of caphead instead.

If in doubt get them longer and can always be trimmed down.

Thread: Cast Iron stress relieving
14/03/2019 05:29:05

Right now if you can keep the rain off it then a blower isn't needed

Mad March days can be useful...

Thread: Making nameplates
13/03/2019 20:39:59

Possibly an off-the-wall suggestion but have you consdiered popping the brass into a waterproof bag and boiling it for long enough to get to temp before applying the sheet?


Thread: What thinner for Enamel paint.
13/03/2019 00:01:10

Paragons website states not to make the mistake of using other thinners.. specifically mentioning cellulose thinners. Their hazard sheets says PT8 is solvent Naphtha (petroleum) which I interpret as a subset of oil distillation. Naphtha isn't really specific and might include things like white spirit or turps substitute.
Is it worth risking disappointment? If going to try it then obviously on some scrap first.

Thread: Telephone / Internet Scams
18/02/2019 09:33:10

Perhaps they have a morality limit to their scam... or the tick box doesn't go high enough

(or they have a special scam for the 85+ group hoping they're demented and gullible)

Thread: Tube Seam
18/02/2019 07:38:18


Rest assured that engineering standards and principles apply in surgery too (within their necessary subset) as do their specialised terminologies. If you ever get a chance to look at a modern orthopaedic text there is data on stress loading, application of supports related to tension sides of structures, forces across joints and so forth.

Thread: Tube Seam
18/02/2019 05:49:34

There is undoutedly a cross-over in terminology but pipe implies rigidity and tube implies flexibility as in windpipe or fallopian tube. If in doubt call it a duct and that way it can be a half-pipe


Thread: Tubal Cain : 0.5mm holes : spade point bit needed ? why ?
16/02/2019 09:51:07

I'll have a crack at speculating on the answer here (but it is just guesswork). According to tom's techniques the problem with tiny twist drills breaking is having a drill that can run fast enough. And of course any twist drill has a thinner core than it's cutting diameter which essentialy makes it weaker still and more prone to bending and wandering. A spade end is also going to be less challenging to sharpen and easier to hone without losing temper.

I've never tried drilling such tiny holes in steel but I have used tiny bone pins like that for orthopaedic fragment repair and as pilots for wire holes..less prone to wandering on starting the hole and can be used in a hand chuck (into bone). If the hole wasn't of any great depth then I have popped bur-holes that size through orthopaedic steel using a high-speed water-cooled dental drill bit but at 1 to 300,000rpm it's a different ball-game.


Thread: Countersink choices
30/01/2019 10:39:22
Posted by Douglas Johnston on 30/01/2019 09:53:02:

I find the Weldon style zero flute type tend to be more forgiving than other types and cut very cleanly when sharp. Not so easy to sharpen though where the cutting face is formed by an angled hole through the cone shape.


I've not had need to sharpen mine yet but always planned to spin it up in a cordless drill and offer it up against the belt sander?
What I like about them is one can debur a hole quickly in a hand chuck.


Thread: Lunar Eclipse

Persevered? Lol. I just happened to get up early and went out to unlock the barn and noticed a dull light above the hill. "Oh bless my soul" I paraphrased.. it's that bloody moon thingy, I wonder if the camera is charged and the gap in the clouds will stay?
