|Thread: New coffee maker - disgusting taste!|
I cannot get going properly in the morn without tea. I use a tea bag and brew with cheapo bottled supermarket water (about 17p for 2 litres - our tap water is foul) in a pre warmed mug with a lid (saucer) on top.
I wrap a tea towel (its where the name came from - did you know that?), round the mug for insulation and infuse for exactly seven minutes - I have a timer on my desk for that sole purpose. I season my brew with a third of a teaspoon of unpasteurised acacia honey and a splash of semi skimmed and sit at my desk to enjoy reading the latest posts on this forum.
I like to start the day with tea and then drink alcohol.
|Thread: bunging up hole in CI|
I have this problem fast approaching but I intend using JB weld to fill the 'oles. I am also going to experiment using high build primer on the castings to - hopefully - smooth out some of the imperfections on some of the castings.

|Thread: Alternative materials|
Brass it is then chaps. I like the idea of cast iron and steel but I'll go with brass on the basis that it is one thing less to rust on the engine. Thanks for your comments.
I'll soon be ready to machine a pair of eccentrics for my ongoing build. The two gunmetal castings are missing from the set of second hand castings I bought. I could order a pair from Reeves or alternatively machine the eccentrics (which wrap around a 1" dia. sheave) from some 1/4" thick brass plate I just happen to have.
I am reasonably certain that the brass should be OK but what will the judges think?
|Thread: Cheap 3D printers|
I bought one of the ALDI Balco 3d printers a few weeks back. It was brain dead on arrival - would not power up. After customer support led trouble shooting they advised that the power supply must be dead. Unit was returned and full refund issued without a problem.
A week after I returned it I noticed they had reduced them by £50 to £250 but now I see they are back up to £300 again.

|Thread: Hi from dorset|
Times like this make me wish we still had our caravan at Bowleaze Cove so I could join in! Welcome Phil.
|Thread: What Did You Do Today 2019|
Just back from a short trip to our local Emmaus to check for anything interesting bookwise. Bought a book titled "British Steam Engines" and another on the history of Sywell aerodrome.
I could not help admiring the lovely German made grandfather clock they had which chimes beautifully on the quarter, half and the hour and has moving moons.
So I bought that as well.
Got home and realised we had forgotten the milk.
|Thread: Where to begin?|
Dave - At 72 I am not looking for a job CAD/CAMish but if were I would have read your post with great interest. Very informative and well constructed - well done!
|Thread: Digi ME MEW not working|
I'm not to hot on android technicals but the ME and MEW apps suddenly no longer work on my tablet. If I finger click on the two icons I just get a spinning circle. All seems OK on my phone - they work OK.
I am reluctant to uninstall both apps and re-install as it will probably mean I will have to go through that tedious procedure of downloading all the magazines again. Am I missing something?
|Thread: Skyhooks - an overhead solution|
Anyone who suffers the "nuisance" of magnetised tools in their workshop obviously does not have one of these:
This example lives under a bench but is rarely used.
Like Mike P though I also appreciate the benefits of magnetic screwdriver tips. With my shaky mitts it often makes things so much easier for me. For this reason ALL my screw driver tips are magnetic. For non-ferrous fixtures I use a dollop of blutack - does the same job!
I find it very trying looking for a particular hand tool which has hidden itself from view and with no wall space left to mount tool racks the tools remained in cluttered drawers.
So I eyed up these magnetic strips in either LIDL or ALDI (I can't remember which) and thought they might come in handy. The only vacant space to speak of in my workshop is the ceiling so that is where I fixed'em. My screwdrivers and nut runners now have a new organized home. It still does not stop me scratching my head though when I glance up and spot a gap and wonder where I left THAT one!
Initially I had thought the magnets might not be strong enough for the job but these "skyhooks" are well up to the job and in the two months or so since they have been up there nothing has fallen of.
|Thread: Metal cutting bandsaw|
To save on space (of which I have little left) I tuck my WARCO CY-90 band saw between the end of a bench and one of the lathes. I shortened the 4 legs by 3” and fitted castors so it can be swung out when needed.
|Thread: Not sure what I have here!|
Martin - The cylinder piston type valve and shape of cylinder casting should narrow your search somewhat. I would guess that the alternative slide valves designs on a 3.5" gauge set of loco castings are more numerous. Good luck.

|Thread: Alum as metal remover.|
You can buy alum rock chrystal from lots of outlets. I have used it on my pits for years now after developing an allergy to deodrants. I expect someone will tell me its the wrong sort of alum though.
|Thread: CNC engraved tool rack|
Martin - Thanks for your interest. I didn’t do the drilling on the CNC as I have not yet worked out how to include tool changes in a machining sequence. The hole positions were just spotted using the same engraving cutter after the numbers had been engraved. This was my first opportunity to do useful work with the machine and I was impatient to see a result.
Impatience rewarded its now back to the learning curve - more like a vertical climb - phew!
Hello David - No I did not drill the holes on the CNC. What I did do and what the movie did not show is that the hole positions were spotted with the engraver cutter after the numbers were engraved and were then drilled on my bench drill afterwards. Thanks for your interest.
Just finished making a numbered tool rack for my CNC mill from a “perspex like” material. This was my first attempt at CNC engraving. The “perspex” to my surprise was not flat enough to engrave so I found it necessary to fly cut it flat on the big mill before starting. To give an idea of size the tools are 6mm / .250” diameter.
Doing the numbering here:

|Thread: Busted tap & brute force|
I am in the (slow) process of building a Double Tangye stationary steam engine using a set of second hand castings. They have been part machined – and not particularly well either!
A lot of the re-work involves opening out poorly positioned holes, re-drilling oversize and filling with loctited studs which can then be re-drilled in the correct position.
All was going well till this morning when I realised that one of my bearing standard castings had a busted 6BA tap stuck in the ‘ole.
Years ago I would have given it to my ‘oppo who would have spark eroded it out for me but these days I’m on my own – “so sort this one out mister” I thought!
First attempt to remove the tap was with a 3mm dia mounted point grinding wheel with nil result. Then I tried a similarly sized cheap diamond version, again, nil result. Both attempts were made using an old mini drill I had bought in a field on a Sunday morn earlier this summer. These days my old mitts are not steady enough to hold a dremel and I do not own a stand else I would have tried that method first. (I’ve put a stand on the shopping list).
I read on the forum recently that somebody (I cannot remember who, so apologies to that bod) had reminded me that carbide was quite capable of cutting HSS. It so happens that I had a part pack of ten cheap carbide engraving cutters earmarked for use for the odd engraving job on my small CNC mill.
Once again and with the drill still set at top speed of 8,500 rpm I bought the engraving cutter to bear on the broken tap and gave it some welly. It certainly made some progress before the tool bit shattered but “nil carborundum” as they say. I fitted a new cutter and had another go. The second cutter was starting to break up when it suddenly broke through and the busted tap was out. It was brutal, it was noisy but it got the dirty job done. I would not subject a nice new posh Proxxon to this sort of abuse but my three quid car boot special I consider fair game.
It just remains to open out the hole to 5mm and tap 6mm for yet another stud and my casting is saved.
I am confident that the high speed was the key to success – it must have been the closest I had been to producing plasma whilst “fettling”.
|Thread: Workshop headphones|
I have never found a need for headphones in the workshop. I have a Roberts DAB wireless which is permanently tuned to Classic FM but lately I have found the moronic advertising to be annoying and distracting so the "gadget" is for the most part these days switched of. I do hum a little though.
|Thread: New phone - no digital!|
Bought a new Android smartphone. Downloaded and installed ME and MEW apps. Activated existing subscriptions on both apps whereupon I find I have to pay for all my digital editions.
Phone call to My Time media (a long one) where a chap attempted to help - unsuccessfully. "You'll have to use Google" he finally tells me.
I didn't use google, instead I used my email client and sent a request to firstname.lastname@example.org to cancel both subscriptions.
Drastic? Maybe, but this is not the first time I have had grief re: digital issues.
Lifes' to short for such faffing
