Hey Tug, good to hear from you, send me your address I have a present for you, also if you're not going to finish the 5cc vipers, I'm Happy to complete them for you and send one back to you, along with another surprise if you're keen.

Dean

Soooooo, after a somewhat extended "must get back onto these" leave of absence I've finally fished them out of the dark depths of despair where I left them languishing and brought them back out into the light of living grace and will upload the next few steps in their construction hopefully over the next few days or so.

Cheers

This engine has been languishing on the back burner for quite long enough, I've stripped it down and will commence the long drawn out process of cleaning everything up and doing a bit of a reassessment, after which a full update will be loaded up, along with the flat 12 project that was birthed from my first attempt at machining up the block...........................more to follow soon.

Dean

Have done mate, sorry for the delay, been a bit tied up with work.

Dean

Id Be keen to have/buy them and im fairly certain I have the abilities to finish them. PM me if it works for you.

Regards

Dean Clarke

Well we're back in lock down again so maybe I'll get a look in on this engine project and see if I can't get something done on it.

Hi Mike, I can help with the taplin, PM me for details if your still needing help.

Dean

Yes tug your correct, model engine world was John Goodalls engine mag, sold it on to some guy whose name escapes me ATM but it is no longer in print, I have almost all of the issues if anyone needs something photocopied, happy to oblige.

Dean

Still working on this project too lol

Dean

So...........been a little busy over the last few years and sorta sidetracked. I have however stumbled across this engine sitting way back in the workshop languishing in a sad state of neglect and have brought it forward to the front of the que once again. I stripped it down to check out the inside and give it a big clean and found a broken piston so am now in the process of remaking a set of pistons to slightly improved design. I'll update with photos in the next couple of days.

Cheers

Dean

Hi Alistair, many thanks for the mags, i'll let you know when they arrive, i've paypal'd the money to you.

cheers

Dean

Hi, yes still going on that project, be rather busy of late but will try to update the build threads in the next few days or so.

cheers

Dean

You will find that when you heated the silver steel to solder you hardened it but without the next step of tempering you left the shaft hard, and therefore brittle. The sudden shock of the backfire was enough to fracture the component and the running loads brought to completion the part failure. A simple mistake to make when not understanding the metallurgy of the materials one is working with (from my own experience (lol) its usually better to machine the crank from solid anyway.

very nice engine to by the way.

Regards

Dean

If at all possible I'd like to beg, borrow, steal or buy a copy of these drawings to please.

cheers

Dean

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
