Thread: Pontoon Dingy build.

Looks good Cam.

Thinking about doing one too, but dunno If its worth the 80 or so hour commitment when I could just work and pay someone who knows what they are doing.

Yea I guess it depends on how you value your time and if you can get what you want in a brand boat?
Non pontoon would be a lot quicker build but IMO you have to put reserve boyancey somewhere and in a dingy there isint really anywhere else to have it other than humoungous bench seats full of foam.

Keelson welded in and floor shaped and drilled/deburedfor plug welds.



Keel line of the hull went a bit rippley with the welding of the keelson...Was always going to happen with it being so flat.
Won't be noticeable once it is all scratched and dinged up from estuary work

Floor welded in....went well.
Keelson is higher than required to put a bit of a roll in the top of the floor so no water can pool there. Any water ingress(will be lots of water ingress with my skill for netting weed) should roll off the side onto the channel.



Going with 3 bungs at this stage and can always go to some duck bills at a later stage.

Fitt them and some stiffening to the transom and she's in the water.

Ooohhh. Rhymes with.....hunt

Change the 2 Ns for M`s, and the P for a C, and you have a name that I have been called many times

No seat? Do you just sit on the side, if so would that be wierd with just one person?

Yes seats as per earlier in the thread but not fitted yet.

You still using the BOC ac/dc? Rate it?

The single phase caddy? yep welded all the pontoons with it.....110-115a AC 5% positive, that is realistic maximum for continuous welding with it with a 2.4 tungsten and a no cooled torch. I rate it for purge welded ss DC on lighter stuff. ally 3-4mm is really max for a little job 2-3mm max bigger job.
Generally use a 300amp ac/dc 3phase tig with water cooled torch for most work as it is more adjustable/powerful but I didn't want to tie up that machine while I was perking, but for the money they charge the little single phase is a nice welder for sure.

Yeah its so fricken cheap, although they did just put the price up.

The next cheapest 'name brand' seems to be the Cigweld (esab) @ $2100ish.

4mm is probably on the light side for what I'd use the Boc for tho.

Hmmmm i say. Hmmmmm.

All depends what you are doing with it?
Small jobs you will do 6mm easy but the handpeice wont handle 180amp constant and neither will the powersource.
If 4mm is about as thin as you would use I would be looking more in the direction of a mig than a tig unless as I said very small jobs that have to look nice.

What model welder are you using there cam? Is it any good for steel?

The Tig or the Mig? the tig is a boc branded ac/dc.

Its a nice little single phase unit for the money but be aware it wont run 185 amps on stick,it must run more volts and less amps for stick(stick requires more volts for stable arc esp with low hydrogen)

The Mig is a Ewim? it is a pretty flash programmable pulse mig but with the push me pull you handpeice some parameters are not user adjustable and it has a habit of loosing its shit and you have to get the rep in with the laptop to reset parameters which is as gay as a handbag full of rainbows.

The other two we run on steel with no pull handpeice are great.....force arc is incredible.
