Building a scale 1973 Pay'N Pak from plans

And, once again, I'm on hold. I had planned on working on the Elam when I got to work today, didn't happen. The plan was to epoxy on the glue blocks I had cut yesterday, along with a few more that I was going to cut today. That got put on hold real quick when I started looking at where the lower nontrip glue blocks would be located on the sponson transoms. My glue blocks are .25" triangle stock, cut by the manufacturer at 90 degrees on one corner with the other two at 45s. The issue is that, something I hadn't noticed previously, the layout lines I drew when I made the transoms are drawn at 38 degrees, as shown on the plans. That means I need to stop at the Hydroplane and Raceboat Museum on my way to work tomorrow and check the angle on the full sized boat. Since my glue blocks are almost 10 degrees different than the angle drawn on the transom, I will need to adjust one side of the glue blocks that are attached at the bottom of the sponson insides so that the glue blocks will all line up properly. This will also make it so the nontrip lower skins will fit correctly instead of having gaps between the blocks and skins.
While I'm taking measurements, I probably should also check the angle of the inner sponson bottom panel so I can get the sponson frames all sanded to the correct angles so they will be ready to epoxy the skin panels to

Mission accomplished. Stopped at the Hydroplane and Raceboat Museum on my way to work and measured the angles and lengths I mentioned in my last post. What I found is that the plans and I were both wrong:
I was thinking the nontrip lower panel was at 45 degrees NOPE!!!! That angle is correct for the Pak and several similar Ron Jones hulls, but not this one
The plans showed the angle to be 38 degrees NOPE!!!! Not sure where that came from unless it was from the T-2 or T-3 Budweiser or one of Fred Leland's turbines as they were all very simular to the Elam
The actual angle is a much lower 30 degrees YIKES!!!!
So, now the question is do I rework the glue blocks to the correct 30 degrees or the incorrect 38 degrees? I know leaving them at the present 45 degrees won't work at all

Been thinking about it since I got to work and have figured out what's going to happen. I a nutshell, I'll go with the scale option and trim the blocks to the correct 30 degree face angle. This means it's time to break out another tool, a hobby sized table saw:

Since the blade can be tipped up to 45 degrees, I'll tip it to 30 degrees and shave the glue blocks down as needed. Shouldn't be an issue with the appropriate tool

And, once again, life has gotten in the way of building. Between other commitments and work, I haven't had the chance to work on anything 
To make things even worse, I got called into work for the overnight shift so the wife shut me down using the excuse that I needed to get some sleep before heading to work
As things stand now, I MIGHT get to work on the boats next weekend though, in all honesty, I'm not holding my breath

Here we go again, 4.5 months later and I've found that another set of plans I bought were more wrong that I thought.
Went to the Seattle Seafair race on Sunday, partially to see the boats and partially to see people I know on the various teams. I found most of the people I know and met a few new ones, namely Andrew Tate(he's a really nice guy, just for the record) and Gunnar O'Farrell and his father(two more really great people). I also got to do some checking on "Sharkey", otherwise known as the 2007 Oberto and now the Apollo. I knew the deck shape on the right side on the plans was wrong previously. What I learned Sunday is that the nontrip, like on the orange boat pictured previously in this thead, has a lower nontrip angle of 30 degrees on both sides and not the 45 shown on the plans. Just made me happy I hadn't cut out all of the frames for that boat yet. Hopefully, I'll get a chance to work on the boats over the weekend so I can start clearing out my living room

Time for another "pre-project" before I can start cutting wood again. I picked up some plastic from the local TAP Plastics on Saturday. Now, I need to get the time to build a dual jig to cut my stick stock into usable shapes and sizes. That will probably be my task for this weekend, building a jig to cut the 45 degree sticks to the required 30 degree nontrip blocks on one side and the other side to rip the 45 degree sticks in half, reducing the size and weight for glue blocks and nontrip blocks for the two Paks that I'm working on. Wish me luck that I might actually get something accomplished FINALLY
