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

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

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

Just a quick update to let you know I am still working my way through a bunch of mods and alterations to get this engine running properly, low vacuum and poor fuel draw are the main issues and i have reduced the blower drive to compensate for over boosting, (I think, not sure just yet but trying out different things to see. make 1 change at a time Dean).

cheers for now

Dean

LOL yeah top quality lucas starter right there mate, I think it must have been thinking you were still there coz it didn't play ball after you left either., have done the wiring mod to the glow driver and the starter leads. I am planning to get the fuel rail sorted this week, yeah right I can here you from here mate LOL

cheers

Dean

Hey Michael, yeah fairly certain the tea and bickies just ain't gunna cut it mate. definitely was large quantities of the Kentucky variety. lol........ so having thought about it for a bit it seems to me that the fuel system just isn't delivering enough fuel, when I was turning it over on the starter it was running but not enough to keep itself going, but inject some fuel into the carbs and the bloody thing damn near left the bench, until it ran out of prime. If I stick my finger over the trumpet it almost gets sucked into the blower so definitely got plenty of suck happening now. If I get no joy with a much larger fuel rail then I'll try making new barrels with a slightly smaller diameter in them and taper the hole up to the jet outlet. Oh and of course Fix the damn starter!!!

LOL

Cheers for now

Dean

LOL, probably just as well coz I can't get the damn thing to run now!!!!............................................................................................................It fires up with a squirt of fuel down the throat but wont actually start and run, have spent a few hours messing about with different bits and pieces but gave up in the end, the prime tells me its short on fuel so following that up with some problem solving bourbons and will probably try again next weekend after I stop crying and wailing...... Oh and did I mention that the starter seized solid just to really test the limits of human rage!!!!!

Wondering if I shouldn't just give up????................. except I'm far to stubborn for that..

Disappointed dean

Hey Keith, what happened to the video of this magnificent engine running? be good to see it mate.

cheers

Dean
