OK, here is the first picture of my three-cylinder 30cc four stroke. I designed it for spark ignition but test-ran it on methanol with glow plugs. It ran for a few seconds before the crank shaft fractured. I made a new one and never bothered to advance to spark ignition.

That one worked, so here is another one...

Old Timer · « **Reply #2 on:** July 11, 2019, 08:23:01 AM »

Naaaah, more of the "your file is too large" business so I checked the smaller ones and here it is...

Old Timer · « **Reply #3 on:** July 11, 2019, 08:26:41 AM »

Just another one of the three-cylinder...

Jo · « **Reply #4 on:** July 11, 2019, 09:10:11 AM »

I am interested to hear more of your three cylinder engine. Are the cranks at 120 degrees? How did you time the firing

A Kiwi and Whippet

both Westbury designs.

Jo

Old Timer · « **Reply #5 on:** July 11, 2019, 10:17:24 AM »

Hi Jo. Yes the three cylinder has 120 degrees off-set cranks and I think the firing order is 1-3-2 but canna remember so may have to go and check again. This one is responsible for having me make seven camshafts before I got the firing order right.

The Whippet and Kiwi are Westbury designs and castings, purchased from the erstwhile Woking Precision Models, now extinct I believe, or taken over by others. I also have the Seal Major 30cc and 15cc of which I kind of built the small one (finiky small!) and partially made the 30cc one.

There is also the Vega Twin that is awaiting completion and the late Bob Shore's Silver Bullet (image too large...)

I am hunting the pictures of the multi-cylinder models which should be somewhere in the archives - dang it! I hate it when I cannot remember where I put that thingy I made for you know what in the something or other - only yesterday!

I also have some other projects like a single cylinder made from parts of a hospital bed frame... with a cylinder head off a aero model engine. The Webster scratch build which I made in 11 days I gave to a family member. That one sported a .308 Winchester shell case for an exhaust.

Then I still have various other engines like a twin boxer I purchased half-built from a US friend and a 1/4-scale semi- completed V-8 with twin Walbro carbies. Lack of drawings halted the further construction.

Perhaps there is some of you who might want to complete some of these projects, or get their paws on some of my unworked castings stashed away somewhere in my garage. Just a word of warning: I will need time to find 'em!

Thanks for the interest shown so far.

Forgot to mention that I made the crank case and timing gears for a Jerry Howell V-twin for my old friend Mike Baltes who lived in Pennsylvania. That was a challenging job machining the parts from bar stock. Sadly Mike passed away some considerable time ago and I cherish the bits and pieces of useful stuff he sent me - small drill bits, matching timing gear sets, a full set of drawings for that JH V-twin etc.

RIP Mike!

A very nice collection

How did you make the crankshaft for the three cylinder engine, was it fabricated or turned from solid?

I expect Jo is already on her way to raid your castings/part finished collection

Old Timer · « **Reply #8 on:** July 11, 2019, 12:00:45 PM »

Hi Roger

The crankshaft for the three-cylinder was manufactured - one reason why it fractured on first start. Secured (not sufficiently) with pins and brazing. It is also a fairly tight fit in the crank case cavity - not a very neat job

I'll be waiting for the raiders of the archives....

Hemingway http://www.hemingwaykits.com/ took over supplying some of the old Woking models.

If you post a pic of it someone may know what it is and where to find the drawings.

Jo

P.S. We have a V8 Challenger model engine in our casting collection

Thanks for the project pictures. Happy to see you got that sorted out. Any pictures of your shop space would be great to see also.

Bill

Old Timer · « **Reply #11 on:** July 11, 2019, 02:28:35 PM »

Thanks Bill.

Believe me, you do not want to see my working space, especially now that I am in the process of thinning out the clutter, debris, hoarde of stuff, old bicycle parts dating back to when the kids were still at school. Don't want to frighten away my newfound friends....

But thanks for the thought. Next I am going to make an effort to get all the IC engine stuff together. It is high time I get them all in one place. Then perhaps take new pictures and post them. That 1/4-scale V-8 must be lurking in the gloom of mothballed bits, just like the Seal and Seal Major projects.

Anyone into the older (vintage/antique) type engines? Perhaps such as the old Ohlson & Rice, Taplin Twin, and even the later PAW diesel engines?

Nico

Jo · « **Reply #12 on:** July 11, 2019, 03:38:13 PM »

I don't (yet

) have an Ohlson. But I do have a number of early engines and casting sets including the Taplin Twin, Ladybird, M&M, Majesco 45, Pepperall and a fair few others

I often do an early aero engine in between other bigger builds.

Jo

Admiral_dk · « **Reply #13 on:** July 11, 2019, 08:07:55 PM »

I should start with a welcome to you "Old Timer" (I believe that there are several here that could be considered as such

)

I got an original Taplin Twin in marine configuration, but I do not have the other (loose) part of the prop-drive link

an more important as I would have prefered it as an Aero engine - is there anyone here who has drawings for them (even better for all versions) ?

If so I could make the missing parts as I believe that they where originally included when you bought it from new.

Best wishes

Per

Old Timer · « **Reply #14 on:** July 12, 2019, 06:59:39 AM »

Hello Per and thanks.

I have a complete (I think) Taplin twin somewhere. Can't remember if it is a marine version or otherwise. They also came in two sizes, I seem to remember a 15cc and a 30cc version. Cannot even remember which one mine is. Perhaps I even have some more literature on those as well but cannot be sure. (I am sorry to have to often refer to "I cannot remember" but I promise to rectify that as time goes...)

Jo, I have several Ohlsons, also a few other makes such as the Anderson Spitfire and the Super Cyclone, GHQ with its cast iron head and crude cooling fins.... Now I got myself all excited so this weekend I am going engine hunting.

Still have a problem reducing the size of pictures to below 1024 bits. Took some of the Silver Bullet this morning but the confounded thing is over 3mb so I am wrestling to shave some off it...

Nico

Old Timer · « **Reply #15 on:** July 12, 2019, 07:32:09 AM »

OK, I managed to reduce this morning's picture by a huge amount. I trust members will be able to identify the images.

The larger one is the Silver Bullet I scrounged from someone who had machined too much off the lower crank case and discarded the casting. I made a wedge shaped filler and attached the sump so it looks right again. Notice the massive valve rockers which I had to make without drawings. They work fine. The crank handle is fitted for display to show the up and down movement of the valve mechanism. The ignition components which I do not have, are supposed to be built into the bell housing with a lever protruding for advance and retarding the timing.

The other little fellow is an experimental horizontal hit-and-miss type which I started constructing just for fun. It will likely never be completed or run but it was fun and a conversation piece.

Both engines show obvious signs of "hanger rash" which is bad.

Enjoy!

Nico

Jo · « **Reply #16 on:** July 12, 2019, 07:32:37 AM »

Taplin Twins came in 8cc or 7.5cc, or 15cc, air cooled , water cooled, red head, green head.

Any chance of a pic Per of your engine? My Supplier says he may have some spares but he is not sure what there is yet.

Jo

Old Timer · « **Reply #17 on:** July 12, 2019, 07:35:50 AM »

Luvely Jo!

Mine is a green head.

Nico

Admiral_dk · « **Reply #18 on:** July 12, 2019, 11:53:01 AM »

Mine is the original green head. As far as I know they made the red head a bit later before closing down and the 15cc came after a new manufactor took over the brandname.

I might be interested in parts - depending on price - but as mentioned, I would really like to get my hands on drawings. I can take my own appart and make drawings for what I have, but that will still not give me the missing parts, though I could create something that will fit and look right as long as an original isn't next to it ....

b.lindsey · « **Reply #19 on:** July 12, 2019, 02:35:32 PM »

Not able to see the picture Nico. What is a .pgf extension?

Bill

Old Timer · « **Reply #20 on:** July 12, 2019, 03:04:31 PM »

Hi Bill. Sorry about that.

.pgf is reduced by Pixillion Image Converter. Free from NCH Software suite. That was the only one that would reduce it to below 1024 bits. I will try and convert it to a .jpg, maybe it will work then. I even downloaded the paid version of Winzip but it will not shrink files sufficiently. Must find another way....

Nico

Old Timer · « **Reply #21 on:** July 12, 2019, 03:08:07 PM »

Maybe this one works...

b.lindsey · « **Reply #22 on:** July 12, 2019, 04:32:14 PM »

Yes, that did it Nico...thanks.

I hope that they have cleaned themselves up - or more to the point - that package used to install a lot of unwanted thing on your computer while installing what you hoped it would do

Xnview is a great free image edit program that will do what you need here + a lot more

Another proofed free possibility https://www.irfanview.net/main_what_is_engl.htm
I am using it since some years now.

I usually send the image to myself by mail. Apple then give a choice of sizes. Start with the small one, and if it is a bit fuzzy, try the next larger. You will soon work out which size to use. Save the image from the mail attachment, and use that in the forum. It will always be the second image, just after the full size one in your photos.

Old Timer · « **Reply #26 on:** July 15, 2019, 07:25:37 AM »

Thanks guys. I downloaded one and will give it a try.

This weekend I did some digging and came up with a lot of stuff, mostly unfinished scratch-build projects but also some complete casting kits... (that got your ears eh?).

Let me do some photo editing and revert.

Nico

Old Timer · « **Reply #27 on:** July 15, 2019, 12:16:36 PM »

OK, Now I got the hang of reducing picture sizes - anyone wanna come for lessons...?

I am posting some pictures of some of the stuff I un-mothballed over the weekend, for viewing and perhaps drooling purposes...

Enjoy!

Jo · « **Reply #29 on:** July 15, 2019, 01:27:40 PM »

Your 30cc Boxer engine looks remarkably like the 45cc Wall Wizard I have on the bench to finish off

Sorry I don't recognise the Vee 8 model $:-\$

Jo

b.lindsey · « **Reply #30 on:** July 15, 2019, 01:31:52 PM »

Looks like you have plenty there to keep you busy for a while Nico!!!

Bill

Old Timer · « **Reply #31 on:** July 15, 2019, 02:08:36 PM »

I think that boxer is a Wall Wizard. You got drawings for it? I had thought I had some but have not found them yet. Sure they will surface some time.

The V-8 petite is a home design. Something like a design-as-you-go kind of thing. The case has been hollowed out and the crank bearings are made of bronze. Just another one that perhaps will not be take any further by yours truly...

Nico

Old Timer · « **Reply #32 on:** July 15, 2019, 02:14:34 PM »

Hi Bill.

Yes those unfinished projects most certainly will take a while to complete - and I'm a little short on the "a while" bit.

And there may be some more stuff hidden away in the mothballs (does any one know of rust preventing mothballs?

)

What do you think of the "appropriately marked box?" It contains all the messed up bits and parts machined with an indelicate or too heavy hand - I am sure if we all do not have a container somewhere with those bits we have not experienced true hobbying!

I believe that it is called oil in certain parts of the world.
