I pick up the plans from Glen-l. Frames and keel has been assembled and I am creating the template to plate the hull right weigth.

JPG File size: What do the plans call for? What types of tools do i need to bend the two halves together? Also how can I calculate the curvature of the boat to build this form? Great advice, but it seems like a lot to go through given I have the frames set up and the template for the hull plating ready.

The boat is 20 feet long by 8 feet wide i re uploaded the picture of the boat as it sits today. This boat is obat one off as most boats foo by amateurs. Personally building a CAD model of the boat aaluminum then creating a mold for it seem a bit excessive. I appreciate your help, anyone else have some ideas? Edit: Just had a relook through the pictures, so I think I have a better idea what you are asking.

The normal way is to simply apply pressure with timber lengths and compression straps until the plate conforms to the metal jig. You can hold it in place with clamps at each edge with clamps alone, or you can use timber strips clamped over the aluminiumwith the timber clamped to each steel frame.

PS - if you get a really difficult piece to bend, this has some info. More details of pulling plates to frames. Note how they drill a hole through the bottom of the sheet, and insert an eye hook, so they can pull a curve into the bottom sheet at the bow.

Found a good video on the welding process for aluminium. Thanks for the info!!! I appreciate the feedback. What type of boats have you guys built? Some comments Our 02 was building 18 to 24 foot by 8 foot beam aluminum jet boats but have built up to 36 feet. This is considerably different than heating steel to a red hot phase and having it hold its shape. Aluminum oxide has a higher melting temperature than the 14 Ft Aluminum Boat Weight Capacity Network aluminum underneath so the shape can be retained until the outer temp is reached and entire section can just fall away.

As an experiment, take a length of aluminum and heat it and you will discover what I am explaining. We had temp sticks, a crayon, that as we heated the stringer, we would just take the crayon and make a mark with it on the heated aluminum, if the crayon melted and got shiny, then that is the temp of the material.

I do not want to give you inaccurate information here but, memory is questionable, I think we used degree temp 2 The sweep of the bow appears quite tight. Generally if the bow has a fast or tight curve then the chine cannot also 20 foot aluminum boat weight game the same tight turn or the weiight will not fit flat.

20 foot aluminum boat weight game you have a plan from aluninum known builder, there is a good chance that the two are compatible to make a developable surface and that the sheet will in fact fopt on both edges tightly. As 220 built on 20 foot aluminum boat weight game steel, male jig, we had tabs welded on the male jig and if a piece of aluminum was not snugging up, we would get under the jig and drill up through the hull, drop a bolt in it and pull the plate down to the jig.

After, just don't forget to weld up the holes. You should make the template as one compete piece, joining the ply with a thin batten at the 8 foot intervals, thin so that the shape or curve of your pattern is not impacted from the hard spot that a heavy batten can fame at the joint. If you make a template from small independent pieces there is a chance that you lauminum have fitment issues. Other wise you will have a disjointed joint, had to. Unless absolutely critical, I would not use Tig on a boat hull.

The slow speed of tig 7 welding introduces a lot of aluminum expansion into the sheet so that you actually weivht weld in deformation in the hull. Some will say not, and occasionally we used Tig but not 20 foot aluminum boat weight game. When you are aluminun a butt weld you must cut out the backside of the weld before welding the backside.

Most important!! Aluminum work hardens extremely easy. And the stress concentration due to the notch effect can cause failure seight to small localized work hardening 8 Also when you start and stop any long seams, you 20 foot aluminum boat weight game cut back the bead where you stopped to ensure that when aluminu, stopped the first bead there was not a weld crevice due to the bead cooling quickly.

You can try this out on some scrap. If I think of anything else Aluuminum will let you know. BarryFeb gxme, Thank you for the input. I will post some pictures of the progress. To see the exact path of the blade into the back side 20 foot aluminum boat weight game the joint, you have to get quite close to it.

This is a recipe for a disaster as with the exposed blade and being close to the saw, they can kick back and the carbide blades do not slow down for organic material. It was a safety policy in our shop that any potential kick back path did not cross over a 20 foot aluminum boat weight game, leg. They have less mass and if they bind they are harder to control kick back but sometimes due to access, they are used.

Fpot two levels of eye protection, only as your head is so close to the hot chips, safety glasses and face shield, Did not 20 foot aluminum boat weight game to be so wordy, but this is one of the most dangerous hull welding processes of aluminkm a hull, short of dropping it alumknum someone when you roll it.
