VC you are indeed a man with talent. On another note there were 3 mini jets parked outside Marine and General today in various states of completion

Just turn it upside down its perfect!

Off to see Tui at M&G morrow hopefully

How about a flat pack and some beers for a perky @veitnamcam ?

I dont really want to cant really perk after hours cos gotta get home so wife can go to work and weekends is kids or hunting.

step one, buy a cheap arse mig and a bottle of argon.
step two, buy a roll of 1.2mm alloy wire(might get away with 1.0 mm but will have to be real carefull to keep the lead fairly straight)
step three stick it together and practice on some scraps.
step four weld the bugger up.

I do 90% of our alloy mig welding with a cheap 180?amp single phase mig welder. got to be a wee bit carfull to keep the lead straightish not having a pull hand peice but its all good, only get the miller pulse pushmepullyou big clumsy prick of a thing out when I have to.

How about during work hrs??
What's smoko worth for the next month ?

Surely someone in welly can weld?

Yeah .. I can to... It's just a time thing.
Finished boat is prob the best idea I think

Yep time,mans greatest enemy

I'll get ya some pics if you like when i go past M&G tomorrow.

But the Miller sounds so much nicer

ive seen some horrible aluminuim mig welds.. a lot faster than the tig tho.

I think it cost my mate 1500 for the material time and welding it up

Fo Spanners, Driving past one of the local engineering workshops I found these out side (and 1 inside, and one down the local river)

My mate built the two stacked on the trailer .
Top ones 8 ft 550 pole ski engine and unit . Weighs about 180kg and good for about 60 kmph
Bottom ones a 9 footer , 750 Kawasaki ski engine and unit . Weighs about 200 kg and good for 65-70 kmph depending on how rooted the unit is at the time .
Like a few guys now he prefers smaller 4 stoke car engines (Suzuki m15a /Toyota 1nzfe ) for reliability and noise .
If your set on using jetski engines plan on rebuilding a few of them .

Gotta love them 2strokes

I was set on a 1100cc 11" boat... The old boy thinks we need 14"...
Will do some more research
I like the 4st idea as less maint, but also like the 2st ski motors as less weight and have rebuild a few and like the kawasakis

Not going to build as dont have the time so will buy finished boat
