December 2021

From the Editor - December 2021

Season’s Greetings - welcome to December 2021! Another year drawing towards its close, and it’s certainly been a weird one! What with the ongoing pandemic, the disturbing levels of ongoing political and social dysfunction and the continuing and growing impact of climate change, it’s certainly true that we live in “interesting times”, as the old Chinese proverb has it!

Here on British Columbia’s We(s)t Coast where I live, we’re well and truly into the grip of early winter. The issue is not temperature - if anything it’s warmer than usual - rather, it’s the amount of excess water sloshing around as climate change tightens its grip.

Many of you will have become aware from the news that British Columbia has been experiencing record rainfall and early flash snowmelt events, flooding a number of residential and agricultural areas and causing a far higher-than-usual incidence of washouts and slides affecting major transportation routes, thus seriously disrupting essential supply lines. A number of entire communities have had to be evacuated due to the flooding. As you might expect, there have been a number of associated fatalities, while the livestock losses have been staggering. Lorna and I are OK - we live on high ground well away from any watercourse. Others have been far less fortunate ……… My sincere thanks to the many readers who sent their best wishes for a safe passage through these troubles. Means a lot to me ..........

The increasing frequency of such events worldwide is an inevitable (and predictable) result of ongoing climate change. British Columbia isn't being singled out by some malignant influence - it's just our turn ......... Since the recent Climate Change Conference in Glasgow has confirmed that the global response to this problem is going to fall well short of what’s required, I suppose that we’d better get used to it. I truly pity our grandchildren …………

The pace of our Covid-19 infection rate in British Columbia continues unabated at near-peak levels as the widespread surrender to the pandemic has continued. There’s now no doubt that thanks to the anti-vaccsers, anti-maskers and quarantine-breakers, Covid is here to stay - the recent massive surge in infection rates in Europe and the speedy arrival among us of the Omicron variant have clearly demonstrated the effects of relaxation with so many unvaccinated and irresponsible individuals running around. Several countries are re-introducing restrictions, with more set to do so. At least some governments are finally starting to act as if they recognise the seriousness of this problem. About time ……….. I just got my third shot, but that of course is no guarantee of immunity, nor does it prevent me from picking up and spreading the virus, even if I don't present symptoms myself.   

As always, the anti-vaccser anti-masking crowd are being their usual mindlessly vocal selves, protesting measures which are now primarily aimed at saving their lives given that the majority of deaths and hospital cases (but sadly not all) are now among the unvaccinated. Ironically, those protesters are the very people who are primarily responsible for the need to impose the restrictions to which they object so vociferously - by spreading the virus and facilitating the evoulution of new strains, they're killing themselves and taking some of the rest of us with them. Their current campaign of harassment of parents bringing their kids to vaccination centres utterly shames them. For me, the last straw was their recent invasion of a number of Remembrance Day ceremonies on November 11th - they couldn’t have shown their total lack of respect for others more clearly. The attached parable sums up my contempt for these people's reasoning abilities very well.

Thankfully, life goes on at various levels even in the face of such crass stupidity and irresponsibility. For my valued readers, this very much includes a continued interest in model engines! Indeed, the site usage stats for November 2021 show that the increased level of interest which I've been documenting over the past few months has been well sustained! The 548,966 number of hits in November was a little down from the corresponding October figure of 620,618, as was the number of visits, which fell to 5,384 from the October total of 6,163.

However, there was still good news! I was encouraged to note that these visits came from a still very healthy 3,345 unique visitors, making this the fourth straight month in which the number of unique visitors has exceeded 3,000 individuals! Between them, the November visitors accessed a slightly reduced total of 24,490 pages, which still represents an average of almost 5 pages per visit. I seem to be maintaining a high level of ongoing reader interest - a good sign for our hobby! 

These figures confirm that despite the COVID-19 pandemic and the accompanying societal dysfunction, a significant number of folks are clearly remaining very much engaged with our hobby. Further confirmation comes from the fact that the mail box has remained very active. I heard from quite a few of you during November, including (in no particular order) José Manuel Rojo, Luis Petersen, Tim Dannels, Peter Valicek, Maris Dislers, Tom Coletta, David Burke, Dean Clarke, Dave Zwolak, Ingemar Larsson, Michael Noakes, Kevin Richards, Sergio Montes, Gordon Beeby, Bjorn Baal, Jim Lindqvist, Mans Hagberg, Sten Persson, Michel Rosanoff, Paul Smigelski, Bob Christ, Andrew Boddington, Chris Ottewell and Neill McRae. Apologies to anyone whom I may have inadvertently missed in the crowd, and apologies also to those whose messages went unanswered. The blog site has continued to justify its existence by contributing a small but steady flow of relevant traffic - thanks for that.

An extremely informative contact came from my good friend Mike Noakes of Launceston in Cornwall, England. Mike has done some in-depth research on the history of the original facilities of the E.D. company on Villiers Road in Kingston-on-Thames, Surrey, England. He was able to provide a capsule history of the site up to the point at which E.D. commenced operations there, also locating several air photos of the E.D. facility (the large rectangular white-roofed building with the multiple skylights). I’ve added this material to my E.D. article with my very sincere thanks to Mike.

Another greatly appreciated contact came from my good mate Peter Valicek of the Netherlands. Peter recently got together with Dutch model engine historian Tom ten Brink, who showed him the sole known example of a twin ball-race rear disc valve version of the 2.5 cc Thuella Favoriet flutter-valve diesel which was featured in these pages last month. This was evidently a prototype of a revised design which was under consideration as a replacement for the original flutter-valve Favoriet. As history records, this model never actually reached production. My very sincere thanks to Peter and Tom for their kindness in making me aware of this prototype, information on which has now been added to the Thuella Favoriet article.

Peter is currently working on a couple of important restorations for me which will eventually lead to several very interesting articles on a few unusual topics. When I started this website way back in April 2014 I used to wonder how long I'd be able to keep coming up with new topics for presentation each month. Well, here we are 8 years on heading into 2022, and there's still no end in sight! I suspect that the list of potential topics may well outlast me!!

But Peter isn't done for the month yet!  He also sent along the attached image of a diesel of around 1.5 cc displacement which neither he nor the owner can identify. This one has been driving me nuts - I know that I've seen it before but can't put a name to it. That oversized web beneath the main bearing is quite distinctive, as is the rearward bend in the fuel pickup nipple. Can any kind reader put me out of my misery?!?

It was a great pleasure to hear from Bjorn Baal, who took over Frank Bowman's piston ring-making business some years ago and is still going strong under the trade-name RMJ Machine Worx. Bjorn has rings in stock for most of the more widely-used models and can supply rings for models for which he doesn't have specifications - just send him a few accurate measurements, and back comes a perfect set of rings! My example of the Mikro 5 cc racing engine has Bjorn's rings fitted, and it's a great performer. I've heard from a number of more recent customers that his work continues to be of the very highest quality. So don't give up on that clapped out old ringer - get in touch with Bjorn and give it a second life!! I have a candidate myself which will soon be receiving Bjorn's expert attention.

I was delighted to hear once more from Ingemar Larsson of Sweden, who tells me that he is hard at work on the next issue of the wonderful LINA control-line magazine. Ingemar reports that this issue will have a strong focus on model engines - it will include my own article on the Komet sideport models from Sweden as well as a piece by Maris Dislers on one of the Bušek-FROG models from Czechoslovakia (as the Czech Republic was then). As if this wasn’t enough, there will also be a contribution from Gianmauro Castagnetti and Gianni Mattea on the subject of Rossi prototype work in the 1960’s. Finally, there will be a how-to piece on taking care of your Webra Record diesel for the Weatherman category. There’s still time to become a subscriber so that you won’t miss out on these goodies!

As always, the latest issue of “AeroModeller” magazine was a welcome arrival in my mailbox. I’ve said many times that if you retain any level of interest in “traditional” aeromodelling, you need to be an “AeroModeller” subscriber! The magazine has been running a capsule history of the E.D. range from its earliest beginnings up to the present day - issues 1013 and 1014 for October and November 2021 respectively presented the first two installments, with the final installment in the December issue (no. 1015) which just arrived in my mailbox. The author is none other than my good mate Kevin Richards, who is undoubtedly the world’s leading authority on the E.D. range. Kevin tells me that he is continuing to work on his book on E.D. which will doubtless represent the last word on that topic.

Speaking of E.D., the December issue of "AeroModeller" also features a test by my good mate Maris Dislers of the two lovely little Redfin Mini "B" and Micro "B" diesels which I mentioned previously in my October edition. These beautiful little creations are based on the classic E.D. Bee 1 cc model but feature a whole slew of improvements, including twin ball-race crankshafts. Maris's review does them full justice. I’ll say it again - if you’re not an “AeroModeller” subscriber, you’re missing out!

The same is true of Tim Dannels’ ever-informative “Engine Collector’s Journal” (ECJ). The latest edition (issue 264) arrived in my mailbox, providing some interesting reading as always. This issue features two pieces by Yours Truly - my “favourite dozen” model engines and, just to present a balanced view while rattling a few skeletons, my “least favourite half-dozen”! Once again, you need to be an ECJ subscriber to get all of my writing and that of some of my valued colleagues!! Quite apart from that, Tim’s outstanding efforts to keep ECJ going over the decades since its establishment 60 years ago (!!) richly deserve the support of everyone retaining an interest in model engines. If you haven’t already done so, get on board!!  

Turning now to this issue’s lead articles, this is the Christmas Bumper issue, which always means a bonus article for your holiday reading pleasure! However, one way or another we’ve all had such a challenging year (which is not over) that I reckoned that my faithful readers deserved a little something extra in the Christmas stocking!  So this edition features not one ……… but two extra bonus articles to go along with the usual new feature article plus a “Model Engine News” (MEN) transfer effort.

For this month’s all-new featured lead article, I’ve finally got around to responding to numerous reader requests by presenting a detailed review of the iconic E.D. 2 cc sideport models first introduced  by E.D. during 1947 - the Mk. II and the Comp Special. It was the positive reception of these designs that got E.D. off to a good start in the model engine manufacturing field. The article records the numerous detail design changes which the engines underwent along the way, together with test results and comments on performance improvement. I’ve also covered a certain amount of controversy which swirled around these models on occasion. I think you’ll find it to be quite interesting!

The MEN transfer article for the month keeps the E.D. theme going by covering the companion model in the early E.D. line-up, the 2.49 cc E.D. Mk. III  rotary valve unit. The original article which was prepared with the invaluable assistance of E.D. guru Kevin Richards remains available on MEN, but I’m able to add considerably to the story at this point in time. Once again, the detail changes which were progressively applied to this model are fully described, along with performance data. I’ve also included the results of some experiments which I conducted to determine how far short of its potential the production version of this engine fell. Suffice it to say that my findings clearly demonstrate that E.D missed a golden opportunity by releasing this model in an under-developed form which stifled its potential almost completely. Fascinating stuff, I think you’ll agree!

The first Christmas Bonus article stems from a contact from my friend Sten Persson of Sweden which I mentioned several months ago. Thanks to the very authoritative information provided by Sten, I’m able to present the full story of the BOMA engines which were the only model powerplants ever to be produced commercially in Indonesia. It’s a somewhat bittersweet tale which reflects enormous credit upon the individual behind the BOMA series, Mr. Tan Hien Tjong. I find it to be an inspiring testament to enthusiasm, dedication and determination against the odds which is well worth recounting.  I hope you’ll agree.

And last but by no means least ……..yet another contribution from my good Aussie mate Maris Dislers, who recently took advantage of an opportunity to sample a very fine replica of an early pioneering diesel from Italy - the Ercolino 2 cc diesel from La Spezia on northern Italy’s west coast. This was one of a number of Dyno-influenced early Italian models which appeared while WW2 was still raging. Original examples are scarcer than kangaroos in Katmandu, but Maris was favored with an opportunity to examine and test a superb replica made by the notable Italian engine builder Alberto Dall’Oglio. He’s been kind enough to prepare the article which is presented here for your holiday reading pleasure. Big thanks to Maris!

For next month, we’ll head back across the Pacific Ocean to Japan for a long-overdue look at one of my personal all-time favorites - the Enya 15D diesel which first appeared in late 1956. This 65-year old classic had a major impact upon the thinking of model diesel designers of the mid to late 1950’s, being copied by MVVS and Dremo as well as pointing the way towards the Schnuerle porting system which was to dominate model engine design from the mid 1960’s onwards. To me, it represents one of Saburo Enya’s finest accomplishments. I hope that you’ll agree when you read the article.

The MEN transfer article will focus on one of the most enigmatic model engine ranges ever to appear in Japan - the STRONG range of 1964-65. The name has nothing to do with the engines’ structural or performance characteristics - in fact, the basis of the name remains obscure. The main factor that sets these engines apart is the retrospective nature of their design - in most respects they hark back to the late 1940’s, with a performance to match! This being the case, the over-riding question becomes - why were they released at all?? My article won’t answer that question, but it will provide some basic information about this obscure range.

I think that about does it for this edition. All being well, I'll be back to you with another edition on or about January 1st, 2022. Meanwhile, please accept my best wishes for steering a path through the present pandemic situation and accompanying social dysfunction to make the very best of the coming festive season. Take care and stay well - pay attention to the doctors and scientists, watch the numbers, minimize your contact with the Covidorks, get vaccinated to the max, continue to exercise caution and trust your own informed opinions rather than those of the Covidolts and their uninformed self-centred supporters!! Your well-being is not on their priority list - put it on yours!

Cheers,
