So not quite the naylon viper engines which are still languishing in the back burner but a step in the right direction at least......................... being that they're diesels anyway lol, just completed these two engines as part of the WOHM engine development program i'm involved with.

regards

Dean

Yeah I wonder about me too ......... REGULARLY lol

Dean

Well as its been quite some time since my last little model engine confessions and even longer since updating this thread I thought it high time i pulled finger (as they say) and posted a bit more on the V12 project. I decided to do a bit of a rethink with this engine and went ahead and made some sand casting gear and cast up a couple of new cases for the V12. photos below show the depths of insanity that some will sink into if left alone long enough.

So hears the end results

Yeah I know I said a couple but if I want to end up with at least one good engine I should probably allow for so oopsies, lol

cheers for now

Dean

You can also set up a gang saw in the milling machine to the correct thickness and gap etc and rotary mill them all in one go, way quicker and easier than turning each fin separately, especially if your making more than one cylinder head.

Just a thought.

cheers

Dean

No Problem, will pop them in the post this weekend, sorry it took so long mate but we got there in the end.

Cheers

Dean

O.k. here is the latest on these rods. below shows the progress

And.... all finished

You may want to polish the crankshaft mick to ensure a good running surface, also double check the diameter before I post them back to you and let me know, should be a nominal 10mm or 9.98ish. Oh and also don't forget to torque the big ends down to the correct setting, which is 0.35nm

cheers

Dean

So here's a quick photo update to show the comparison of the OS Gemini rod to one from my latest Supercharged two stroke V8 project

So anyone know the torque settings for an m2 big end bolt or perhaps the torque setting for the 0/80 bolt used on my V8 rods, I generally just use the torque setting of T.E. but not the F.T or E.F.T. and I've found that using the tightening instructions of " tighten till it shears and back off half a turn " doesn't really go to well either. i'm fairly certain that foot pounds and inch pounds torque on either of these bolts would result in the sheared off torque setting and that would be a bit of a waste of time. so anyone got any bright idea's. LOL (i'm kidding of course, no-one torques small model engine bolts, you don't have the same distortion when machining as in full size practice, well nothing that's actually measurable anyway.)

cheers

Dean

HaHa, well they are in fact fairly big compared to what I normally make, I'll post a photo showing your rods compared to some for the engines I'm currently building.

cheers

Dean

OK so on with the show................... outside profiling under way

next its onto radiusing the little end and the outside flanges of the big end, although as I have a few other conrods to get to this stage before taking the machine vise off it may be a few days before more swarf is made from these blanks.

Cheers

for now

Dean

Hi Keith, been some time since we heard from you, just checking all's well??

Regards

Dean

Well I've finally found some spare time to get on with this help out project, here's some photos to show progress etc.

Now for drill the big end caps etc

caps........

Drilling and reaming the big and little ends

Now we're already to profile the outside

Now I better get back to the shed to finish these off for Mick

cheers for now

Dean

Thanks, although I am still trying to get the time to run it up again as I have made and fitted a new set of carb barrels and also Refitted the toothed belt blower drive with a slightly different drive speed so it will be interesting to see how they affect the running, If it runs at all that is

Cheers

Dean

Ok well I just uploaded to youtube so let's try that again shall we.

Ok try highlighting the link and then right click and select the go to option. should work

cheers

Dean

Well as far as vid's go, apart from the previously posted ones there's nothing new to show. engines above aren't quite finished yet but, rest assured, as soon as I get my A into G and finish some of them the filming will start, not my backside this time either lol.

Cheers

Well let me start with an apology to anyone left hanging from my last post to those of you have have just flatly fallen asleep from boredom waiting for another update. I have been somewhat sidetracked with this project with trying to catch up with some previously started projects that have been left wallowing in despair at the back of the shop.

Photos below show the causes for the delays.

I should have the V12 running again in the next couple of weeks.

Cheers for now

Dean

Hi mick, I would recommend building an matched pair of rods from 7075 t6 aluminium if you want to use the engine much. This is what I use in all my engines that require a split big engine. Balance isn't an issue as the weight is the same for both sides. If you get stuck send me a pm and a sample I'll build you a pair.

Cheers

Dean

OK so thought I should probably post again just in case anyone was thinking I'd given up? No? ok so I have now made a new set of carb barrels and am just now charging up the batteries to test run it again this weekend. I will post the results as soon as I have some, good or not so good.

cheers

Dean

HAPPY NEW YEAR too everyone, just letting you know I haven't really forgotten this thread, but somebody has been suggesting that the gardens need a tidy up so guess that means no shed time for a bit. might need to reconsider that option, see how we go.

will get right back onto it soon

Dean
