The next Cat has landed

[Hood]

Never made it up yesterday due to snow but today I got the frame and plating of wheelhouse done.

Also got the table sheeted and measured up for the hauler box which I will cut tomorrow before I head up to the Cat.

Do you weld that wheelhouse plating in sit-ups it looks? What about heat on the structure behind?

The heat affects it slightly but as there is very little oxygen it doesn't catch fire and just sort of melts it slightly before it again solidifies. If you remove the plate at a later date you see marks but no real damage.

Got the base plate for the hauler cut and two rectangular pieces as well which would be properly cut to the required angle once it was known.
The hauler on this one is a 16" Seawinch and the design of them is not the easiest when getting the alignment of the hauler box worked out. The whole hauler has to be fully assembled and bolted to the base plate and it must weigh upwards of 40Kg and trying to balance that whilst moving and tilting to get the alignment for the rope correct is a real pain.

Eventually we got the angles right and that allowed me to remove the hauler and get the box welded up, the base plate is 600mm x 500mm x 8mm 5083 and the sides also 8mm 5083.

Box welded in.

Hauler properly fitted but the ejector knife block is 2.5mm too high so I will have to skim that off before I can bolt that down.

my Berlingo is tragic in the snow, took me 1.5 hrs to get home when normally it would just be 30mins. I thought when I navigated the couple of miles of backroads and reached the main road it would be fine but it was little better.

Get Winter or All Weather tyres fitted - they make a huge difference.

 

[slim_boy_fat]

Yes, it will be replacing this one.

Aye, they would make it a bit better but for the few days a year we get snow it is probably not worth it.

They do ok, put in the hours though but the main reason is that he got the wheelhouse made a specific way because he was adamant he would only ever have a davit. Now, however, he is feeling the back ache with working deeper water so the roller is the way to go but the wheelhouse design meant it wasn't an option without months of alterations so a new boat was the best option. The old boat is already sold without even advertising, someone in Wales must have heard through the grapevine that it may be for sale so messaged and asked, made a trip up and put a deposit on it, it heads off in April or May I think.

They outperform Summer rubber if it's 7 degrees or lower.

Aye but at 100hp and 50mph legal speed I need some excitement from the sliding round corners

What sort of settings are you using for the mig welding? I had a play with my new hand spool tonight, I was up quite high on the mig settings, 230 plus amps I think (old Cebora transformer mig), the sound was changing from spitting to humming - I guess that's spray transfer? The problem is I have little control over wire speed, if I drop the dc volts the motor stalls, same with current. Maybe a pwm type speed controller might do it. Anyway, on 240 supply it was taking my 30A breaker out..

 

[Hood]

Seems a strange setup for a spool gun, usually you adjust the voltage on the welder and then the wire feed via the spool gun to give the amps you want.

Not sure what current I was running as I just have the EWM set to material thickness view but I will have a look later on today if I remember. I reckon probably well under 200Amps for the 5mm and maybe 200amp or a wee bit more for 8mm.

 

[Hood]

Found this sheet that I had made up a while back which shows the synergic settings for thickness and current with wire feed speed.
Basically is is what EWM are saying for the synergic lines when using 1.2mm 5356 wire.

Nah, John Shepherd boat transport lorry picked it up from the Isle of Wight on Thursday and delivered it Saturday morning.

Cowes Shipyard? I can see the sheds from here, we can still make things in this country.

Not a massive amount to show for yesterday, a lot of the time was spent discussing what was wanted and where it was to go.
Got the hauler knife block skimmed down by 2.5mm and the knife fitted.
Made up a rope guide to direct the rope coming off the hauler.
Made a cleat for the back of the rope guide.
Made a bait box and welded it in to the table.
Made a removable junk shelf below the hauler.

Off for my covid jab shortly so wont be up to the Cat until later on today.

 

[Hood]

I wasn't up at the cat for a week, just got back on Tuesday.
Made up a box to house the 4 batteries.

Cut some 6" x 3" x 1/4" angle down to 5 x 3 and welded some supports of varying heights in.

Then got it bolted to the top of the gunwale and welded to the side plate.

Cut some bits on the plasma for the steering box and started welding that in place.

Got the steering box finished and helm pump mounted. Also cut the top for the control handle box on the plasma and welded in the guard rail above it and the baiting platform frame between the steering box and the gunwale.

Pic of the control box top.

Got measured up for the sides of the control box and will cut them on the plasma tomorrow.

Some more progress, vertical roller brackets welded on roller

Secondary control box completed

Gunwales capped in plastic

.

Main shooting table frame done, ready for lifting onto the boat and fixed in place.

All joints are checked into one another ta add strength and a flat surface on the opposite side for when the 5mm sheets are welded in place.

Skipper and his brother have been getting on with instruments and wiring.

Engines will hopefully get properly fitted tomorrow so I can get on with making up the steering link rods.

Not mine, wish it was, full of stainless fasteners

Got the table frame on the boat yesterday and the skipper and his brother fitted the angle feet to the deck and bolted the frame to them last night. Had another job to do so just got started after mid day and spent the first part lying down on the job welding the sheets to the frame from underneath.

Close up of the welds.

Then it was welding the sheets on from the top with full welds between sheets and as a gap was left they are also welded to the frame from the top.
