Looks like a nice list. I'll try to speak to some of your questions.
Regarding the grip - you have options. On my 3wt I did a cigar shape grip, but another option is the reverse half wells. If you are going to buy a grip, look for one that is inletted .865". When you mount the grip and the reel seat, the front of the reel seat will go into this inlet and the reel seat you choose requires .865". Here is a grip
that would work from JS
Stockard, for about 15 bucks. If you want to spend more and get a fancier one, this .865 inletted grip
is a bit more interesting.
Your reel seat is nice, but the interior diameter (how big the hole the blank goes in) is .550" while the butt section of the blank itself is only .330". That means you will have to build up the blank to be tighter in the reel seat before you epoxy it on. One option is the find a reel seat that as an interior diameter (ID) that is closer to .330 another is to use the masking tape. It might be a big gap, but I'm not sure. You could post a question about it on the Rod Building Forum if someone here can't give you a definitive answer.
Regarding the Tip-top. On the Cabela's site, it says that for the 7' 3wt rod, the tip is a 4 so once you have selected standard/large/or xlarge black tip-top on the Stockard site, add one that is size 4 to your cart. I'd personally do a large or even an xlarge (though that might look too big). A large would give a bit of a bigger loop for knots to pass through and cut down on hang-ups if your leader connection passes through the tip-top while netting a fish or getting the line back out.
I would order 8 guides - it is common to take the number of feet the rod is and add one. For guide sizes, check out the program mentioned in this thread on the Rod Building Forum
. When you put in your rod wt and length as well as the number of guides it will not only give you the guide sizes to order, but it will give you their placement as measured from the tip of the rod.
Regarding the number of spools... you should be fine with one, but order two. They are cheap and shipping isn't. It might not be bad to order a spool of black and one of metallic silver or other colors you might be interested in trying. They are cheap and you can practice wrapping with them. You might end up liking another color or color combo better than blue. It's hard to know till the thread is on the blank.
Also, a few other items with links to what I use:
1. A burnishing tool
to help pack the thread wraps
2. A bunch of razor blades (paint section at Lowes) to cut thread.
3. A 5 minute epoxy
to bond the grip and the reel seat to the blank.
4. Color preserver
- it's your choice how you want to use it but without it the epoxy will alter the thread's color. I use it, others don't.
5. Epoxy for thread wraps I use Diamond II
and also like their self-sealing
. BTW, this company has great thread too. There are other epoxies out there that others might prefer.
6. This pencil
helps mark guide placement while you're working.
, cups, and stir sticks
for epoxy and color preserver. Get two packs of brushes if you're going to use color preserver.
8. A Winding check
. It transitions from the blank to the grip. I linked to a cheap, black PVC check. Since the diameter of the rod butt is .330, I might get checks .300, .276, and maybe .252. They are so cheap it's not worth having what you need. Once you have your grip and reel seat mounted you slide the check down the blank and see which one fits tightly when it gets to the grip. I use a drop of super glue to hold it than start wrapping against it for the hook keeper.
I don't mean to overwhelm your budget, but it's helpful to get what you need so you're not waiting around for delivery later. I tried to link to JS
Stockard when I could to save on shipping, since you are already ordering from them. Many other places carry the stuff as well, but Stockard is good.
Have you found info on how to do the guide and ferrule wraps?
That's probably enough for now. Enjoy
