Pictures of todays progress. A bit less than I thought but a few changes (and that takes time).
I set this up at my first choice of 20 degrees (which matches the F-150 cab.. Didn't like it! Adjusted back to 12 degrees and it looked boxy.. Didn't like it. Finally settled as you see it at 15 degrees. Not too far off the F-150's slope yet better to 'my eye' (just that's what really counts, aye?).
I did even up the curve a bit, then traced out the other side. Clamping both together, sanding until they matched.
Bevel time!
For this I did go to the Skill saw. Worked great! Since this is just an edge cut, no burning, sticking, no issues whatever. For the record (and others safety), I am using a jig saw to rough in all my sections.
I used several pieces to make up the back area that you see. Also marked out where I believe I'll but cutting it for the hatch/entry (hard to see unless you click on the image). When I laid out my top arch/curve I set both ends equal, so that when I get to this point (back in place) I can take dimensions to cut the front sections.
Nope, no roof yet.. Yet now I can rough in the size and make up my sections for the front. They will need to be glued up. Waste not, want not (and it's so easy to glue-up!).
I hoped to have the sections glued up today for the front, yet so much time was used up just getting it where I'm happy with what I see. Hopes tomorrow is to get those pieces cut, get the utility cap off the truck and do a dry fit. Then start all over.. LOL..
Side note: I did try the table saw on a couple of items. Be very careful when doing so! I am a believer that your limbs are much more important than the cost of material. Let the piece fly across the shop! Nope, didn't like that at all.
