Re: Oil as corrosion prevention in bilge?

Well, everybody has their own secret sauce, and as Kevin says, the ACF50 is well proven in aircraft use. That said, I'm sticking with the LPS 3 as it is durable....it forms a waxy, greasy, self healing coating that firms up and does not evaporate, and I've used it on electrical items that are expose...

Looking for go fast deep v center console design.

Since my alloy cat is moving to the PacNW I find myself in need of a replacement boat for offshore fishing out of Port Aransas Tx. Our conditions are rough here, short, steep chop, none of those Pacific rollers unfortunately.Typical run is 40-60 miles into head seas. So, I'm looking for a design for...

Re: Oil as corrosion prevention in bilge?

A bit of follow up here. I'm happy to say the corrosion pits were localized and relatively easy to grind out and tig up. None were deep enough to require plate replacement. We're going to move ahead with the refit and relocate the boat to our place on the olympic pen. It doesn't yet, but will have, ...

Re: Robotics not all that far away!

Well, these automated processes are pretty specific as to which task they can best perform. Fitup and tacking could well be done as well, using the proper fixtures to hold the parts. But since the real task here is to automate the welding tasks it looks pretty doable from here. Now, what I'm going t...

Re: Robotics not all that far away!

I know this is an old thread but of great interest to me. I had a boat designed, cnc cut, and was astounded at the accuracy of the parts. Talking 20 foot hull plates shaped like a banana, pushed into position along the hull and 1 mm max of error. Granted this was from a fairly renowned Kiwi designer...

Oil as corrosion prevention in bilge?

I've got my 28' powercat on the bench for some refreshing. Due to a failed partnership, the boat sat at ex partner's place for a couple years, batteries on, freshwater collecting along with leaves, fishhooks and bilge pumps leaking current. So, some corrosion on inside of 6mm hull plating though onl...

Re: Marine Glass????

That Makralon sounds good. I have thought about those tempered glass windows in rubber gaskets, having one pop out would be not good at all. If I stay with them I'm going to come up with some sort of clamping arrangement on the inside. So, is this abrasion resistant plastic tough enough to withstand...

Re: Marine Glass????

Re: Foam OR No Foam?

I wrestled with the foam issue and spent a fair amount on the USCG site using their calculators and recommendations. As far as the sealed watertight compartments, unless something has changed in the last few years with the regs, the CG gives them zero value for flotation. As a matter of fact if you'...

Re: Longitudinal Twist...

Some impressive framing shown in these pictures. I have to think that these massive frames are primarily to resist bottom and side loads. Your biggest counteracting member for long twist will be your welded floor. That, well attached to your properly spaced framing, turns the boat into a box beam......

I was in your shoes once myself. I bought a set of plans from a good designer and had my parts plasma cut. Recognized my weakness in welding (had never, even once, welded alum) so bought a Powermig with Python gun. Did just what was suggested, had a ton of offcut/scrap and practiced on that. The boa...

I'd go the foam roller route, unless you have an incredibly tiny tip for your sprayer. The stuff goes a loooong ways. It's got lots of VOC's, I recommend an organic vapor respirator.
