Summit Engineering in Rotorua used to have the right gear to do submerged arc welding on cranks - at the time they were the only ones who could do it. I understand they sold the gear to their main customer - a dairy factory or timber processing plant i heard.

I'd be interested in hearing if anyone knows of someone else who can do it.

And no Hus...metalspraying doesn't do it for me. Been there, tried that.

what were they making repairing with it? reactors..................
lead in your pencil Greg?

Yeah...... you maybe, had bad luck or likely bad result with metal spraying Greg but it was good enough for F1 engine cranks it can't be all that bad can it?
It could be mute anyway, regrinding those cranks won't be easy.........
I guess Mike will try to get it running on std bore and stroke first to test the engine before he commits

I used to run that Gleason submerged arc machine at Summit - it is still in Rotorua and still working . The guy who owns it now is also ex Summit and it is still being used.

Can get his contact details if anyone is interested.

The original idea a long time ago was to get this engine going to test concepts.

The original goal was a v-twin with cylinder heads made from cylinders 1 & 4 off an FZR with inlets in the middle. Cam drive and engine management triggers on one side and a CVT on the other. A custom crank running the rods side by side. I was going to supercharge it and use full engine management. I still have the Haltech engine management system and after 2 years managed to get an Aisin 300cc supercharger from Japan. Funny how others are looking at CVTs now. I really need to get on with my ideas when I have them rather than 10 years later.

I had an idea for a bucket front end to get around the incredibly flexible forks. I never did make it but BMW released bikes with essentialy what I was thinking of 2 years later. I still want to make a sheetmetal girder style front end along those lines though I might let someone else be the first to ride it.

Two metalsprayers in ChCh - fail both times....it may work on F1 cranks (though I doubt it) but away from the specialists who do nothing else day in day out we're fucked. Population base size again....

If - as a customer of mine does - you wsh to duplicate the now rather old Norton twin crank that has had the big end journals built up from 1.5in OD to 1.75in OD to use Commando rods....submerged arc is the ONLY way to do it.

Yes it was in the UK I will post it if i can find it. Admitidly it was an odd reson why they used to do it though
But why in the North Island did they need the submerged Arc for a Mill or Factory its not your normal bit of kit now is it.

I was told some rambling story about some f'n enormous piece of kit which had the crucial bit wearing out frequently....the critical piece was apparently priced accordingly so repair rather than replacement made economic sense.

farmaken may be kind enough to dredge his memory to oblige....

Niro power dryer bit maybe they are f-ing huge and incredibly expensive..... thats a stab in the dark that one as i am plainly all hot air Farmaken should get that one

ps havn't found the article but eventually it will turn up.

Don`t know about the milk dryer Husa, but we did some big crankshafts and welded all sorts of things with the gleason - makes a nice job of truck driveshafts

The 125 twin runs.

Observations - it's really cold blooded. Even with the choke pulled it still won't take throttle. It's REALLY hard to start and you sweat a LOT trying. It has a little water leak between the block and head in front of what used to be #3 and is now #1. The little bosses inserted into the end of the cams have a 6mm thread in them to allow mounting of sensors etc. These threaded holes are drilled right through. When you push the bike fast enough oil squirts out the holes. The motor runs really smoothly with no obvious vibration when revving it a bit and if you can catch it on the throttle when blipping it the engine revs sweetly to at least 10,000rpm. With the coolant just running through some hoses between the inlet and outlet it warms up really quick.

At present I would say it has a bit of potential. Not enough to be a winner but enough to be interesting. I'll sort out a radiator, check the timing, have a play with the carbs, and build a pipe for it, later. I think the idea will be to take it to the track for a ride and if it's OK carry on with development - injection, super or turbo charging, and whatever.

Good work Speedpro.

[Rick 52]

Full marks ,very cool

[Sketchy_Racer]

Turbo it!, then we'll have two forms of forced induction buckets running in the North Island. I just finished the design for Mk 2 centrifugal supercharger today so will make a start on that next week.

[Moooools]

Yeah turbo it.

And don't skimp on an ECU either. Get a Link Storm. It is a bit bulky for a motorbike but can do all sorts of useful stuff. Most importantly: Antilag. Also NZ made and have excellent customer support.

[crazy man]

Turbo l think is the way to go. my mate turboed a near stock rz 350 and made 150 rear hp but before he did that he super charged it and found it a wast of time. (l did not want to put this to put glen of cause you never know) ...he thinks the small motors suck way to much hp to make it work right . but the turbo he used was a verable vane one which at high rpm they fall over and let the exhaust work better. but over 2k of turbo
