Frame 3 begins

Been a little while since I have posted. Finally found supplier for marine ply and white oak.
I thought I had inspected the wood well enough... well not so. Upon cutting out a frame member the whole plank cracked and split in two pieces right down the middle. I therein selected not to use any part of that board. The other boards fared better and made sound cuts. So I have all the pieces for frame 3 and some pieces for frames 1, 2, 4 and 5. Shame that board broke. I would have had enough lumber to cut all frames except transom. But thats the way it goes.
Got the West Systems epoxy 105 resin and the 205 hardner. Also a couple of canisters of the 404 high density filler.
Finally got the garage up to 60 degrees tonight so I thought I would give it a go on the one frame.
Glen-L gives instrustions on how to build a layout board with centerline refernces and setup line. Found that not too dificult to setup. Still some of the cuts I made with the bandsaw originally are a little wobbly on the outter side of the frame. I hope that once it gets to the fairing portion before siding I can get the lines of the sides a bit smoother with the sander. I am certain I cant be the only person facing this delimma.
Even with the 60 degree temp in the garage the epoxy didnt heat up in the cup, nor did it go to a gel very quickly either. I am hoping it will continue to get to the right consistancy for the bonding.
I opted to use screws (stainless) for the gussetts and floor timber. On reading/studying I found general notes that nails werent really for structure holding but more of a clamping mechanism until the epoxy dries. I thought if the epoxy doesnt set right and doesn't ever solidify at least with screws I will be able to dissasemble, sand it down and try again with warmer weather.
Not a bad start, and hey we're learning here.

Mock-up frame

Well today I thought I would try my template to make sure it would be sufficient.  I had some pine laying around from prior projects and thought I would give it a go.
Simple enough. I decided to mock up frame three, since it is probably the largest of the frames being midship.
Cutting the frame member with a jig saw seemed to work best for me. I have a nine inch band saw, but I do need to switch to a courser blade before attempting that again.
Ok just going to let you know now... if your reading this I had to type it out on my phone; I left the laptop at work today. My apologie on the typos. Thumbs werent meant for blogging.
Anyway got frame three completed. So I can get a rough estimate that the templates do work. I checked the frame against the full size layout plans and was pretty happy. Also got to see roughly how it will fit within my garage and what space I will have to work around it. Not bad.
This was not a necessary step today but A fun project to do while I await the real lumber.



Templating the Plans

My first inclinations are to continue to study and get ready to purchase the lumber. However, In a recent reading of post on the Glen-L forum, I found out that templates take some time to produce to get ready before the lumber. Hmmmn. Well lets get to that.

At the hobby lobby I purchased poster board, an embalsing pen, and some graphite paper. A few years ago it was called carbon paper, now it's made a little different but still does pretty much the same thing.

Laying out the full size drawings on my largest garage table and placing the posterboard under, sandwiching the graphite paper. Utilizing the Embalsing Pen with its rounded over point I trace the lines of the plan. If you are wondering why not just cut out the parts of the plan? Well, first, these plans did cost a little bit of money. Secondly, there are parts on the plan, like the stem that are quite long and actually are drawn through other parts of the boat. You can easily make out what is what on the plan, but I did need a way to make a duplicate so I didn't end up ruining the whole lot just for one peice. I think this may be clearer once you receive your own plans you will see the connudrum I was referring to.

This process did take a little time. I was able to make temps of frames zero, three, and one as well as the breasthook, and two sets of gussets for frame three. Each different cut piece has to be templated seperately. So to make frame three, there are four seperate peices that have to be drawn seperately to make templates of the parts that go together to make the entire frame. Also marking notes on each peice as to thickness, locations, special cuts, and anything that may be useful when it comes time to layout on the wood. I even went as far as to place a reminder on the template to remember that this is only a half frame so I would need to flip the template on the centerline and draw the other half on the same board too. Anything that may be helpful when doing the layout.
