Re: Where to obtain plans?

2Fish, couple of remarks about your plans as related to your welding skills. IF you post images of aluminum seam welding practice beads then we can compare your work to others online and be able to understand the level of welding you'll be putting on your Jimbo. Not needed of course- you're more tha...

Re: Notes on Metal Boat Building Methods

niko, I fully understand the constraints of time and building boats! I used to build full time - for years and so I have had to get a few fishing boats ready for the commercial seasons and understand that your business needs take precedence over a do-it-yourself build! Good luck with the resulting b...

Re: NEWB- First build Jimbo questions before starting?

Yofish, quick note about the Site's plans catalog. You can put up another page/tab/screen with the Glen-L Plan's catalog links and go to the welded aluminum section (lower on the page) and find the Jimbo as a just under 17' garvey on the plans package links page that pops up. Then click this link an...

Re: Where to obtain plans?

2fish, by posting in the metal category or threads I'll assume you're asking about plans for metal boats? Since the description of the Jimbo is used as an example I'll also remark based on your plan to be a welded aluminum skiff? I'm grouping garvey's in with the other hull forms for the sake of dis...

Re: Notes on Metal Boat Building Methods

North, as I've mentioned regularly, I'm not a fan of foam except when used for insulation above the waterline- and then only in certain applications- none of which involve floating a swamped hull. all the poured foam products I've seen will absorb and retain water, some sooner than others- so I can'...

Re: NEWB- First build Jimbo questions before starting?

2Fish, after looking at the lines plans shown on the plans pages for the Jimbo, I'll remark about one design aspect you may want to consider? IN the Body Section Plan page- the sections of the chine beam taper aft. The chine curves in toward the keel in Plan View as shown by the narrowing chine poin...

Re: NEWB- First build Jimbo questions before starting?

2fish, a welded aluminum, garvey hull form will do all the things you've listed as priorities for your project. A 60"/5' chine to chine (beam on the water) will haul the loads you're describing but a 72"/6' wide chine will do so in less depth or draught of hull. (few inches difference) Usi...

Re: Aluminum repair, can I glass over it?

Started my comments on (bumped/added to) this thread in (an attempted) reply to some email questions I received about transom trouble involving a production, press formed, riveted hull that has a plywood panel as the primary stiffener in the transom of the boat. The boat had a thin skin of aluminum ...

Re: Aluminum Boat Cabins

North, the Hewescraft named "Wilkes Worked" has a standard single curve (cylindrical) top panel as near as I know about all Hewes boats? Their factory is near Puget Sound somewhere so they have access to 8' x 30' sheets (any all other sizes!) in almost any alloy or thickness. So I doubt th...

Re: Notes on Metal Boat Building Methods

mayloga, I've been using Delftship Pro for about 10-12 years, don't recall when I started exactly? Like all interfaces- it takes time to 'get the hang' of new software and I agree with the frustration that Fusion doesn't have a developed surface routine for curved surfaces... I've talked with the 'd...

Re: Notes on Metal Boat Building Methods

mayloga, your description of putting triangles conincident to the proposed bottom panel is accurate but.... I think it would be more efficient for the last long leg of the 1st triangle to be the first long leg of the next triangle- (now.... not being conversant with Fusion 360's sheet metal function...

Re: Aluminum Boat Cabins

North, I will ask a dumb question - is what you are describing in your drawing similar to what Kevin did for the cabin side's (about halfway down page 1) - using preformed/ pre-bent panels except that in the roof the weld edge would be hid by tubing? yes, that is essentially what is being shown- but...

Re: Notes on Metal Boat Building Methods

mayloga, the sheet metal module in Fusion does, I seem to recall(?), have an unfolding routine used to get ducting and sheet metal parts flattened for cutting and future pressing into the 3D shape drawn? usually ducting is made of rectangular panels- but- I was suggesting, to get an unfold feature, ...

Re: Notes on Metal Boat Building Methods

Logan, Fusion 360 doesn't have a 'developed surface' feature yet. However in the Sheet Metal module/tools there is a sort of unwrap that might give a "segmented unwrap" - but not clean B-Spline or T-Splines. So it is very possible (don't know Fusion 360 well enough to say) that you could c...

Re: Aluminum Boat Cabins

Yofish, that standing seam roofing take off solves some really big shape and forming issues for skiff (and larger boats') cabin tops that I hadn't "seen" until re-reading this thread. One of the shapes that is most attractive on a skiff cabin - regardless of size- is the "whale back&q...
