HI
I am new to rod building.. I have a fenwick mooching rod blank can I build that into a spey rod?

So, a pretty generic question without a lot of info. Here's my suggestion:

Spey rods are designed to withstand both heavier line loads and rotational forces due to the casting stroke compared to regular overhead casting fly rods. I don't know the blank well you are considering but here is the research I would do:

Click on the Common Cents info site and read up on ERN, DBI and all the other aspects of measuring your blank. You can approximate the grain window of this blank and see where it might fall with respect to using spey lines. Most spey blank designers go through a pretty laborious process of measuring and testing the blanks with various loads to determine the grain window and taper for each blank. You may not have the facility to duplicate this but you can take some CCS measurements to help answer your question. My strong suggestion is that if you establish an upper end grain window for your blank that you leave yourself a healthy safety margin. If your fenwick blank is glass, it may be a little more forgiving in this regard but it all depends on the wall thickness and taper design.

After you establish a grain window, tape on a reel, some guides and test a few spey lines to see if it's something you want to move forward with. I built a 4/5 spey rod from a 12' center pin float blank. The rod performs pretty well and the customer seems to be happy with it but I did a lot of measuring as described above before I committed to build the rod on his blank (which he supplied for me)

As Tom would tell us, any rod blank will cast a fly line for some distance. Since your mooching rod was designed for trolling and mooching for salmon with a range of weights, it's hard to say how well it will cast a fly line or how it will feel to you when you build it.

Hope this helps but it's not a straightforward answer.

Travis , I would recommend that you not build that Fenwick Mooching blank into a Spey rod. When Jim Green, Tim Grennan or Vic Cutter designed the Mooching blanks we did not design them for the stresses and strains of Spey casting nor were they designed to be used as any kind of fly rod. My experience tells me you would not be very happy with the performance of a mooching blank built into a Spey rod.

Spey rods are very specifically designed and built for that purpose. Trying to adapt another blank designed for an ebtirely different type of fishing and casting can be a prescription for a major disappointment.

Thanks for the info guys.. I am a Fenwick guy through and through.. I will build a mooching rod out of the fenwick and hang it on the wall. I will keep searching for any fenwick spey rods or blanks..
Thanks alot

Travis, what model is your moocher?
I use a few of their old Fenglass 1262 and they are absolutely my favourite.
For me one of the most important attributes of a mooching rod ( the way we use them) is a long soft action, that way with 1oz weight the rod will have a nice full arch and you can see your herring pulling to escape attack from the salmon.
As the others have said this action would not be something I would want in a Spey rod.

my blank is a 1441

Travis, are you looking for another fiberglass 1441?
