        Hey all,

        I’m pretty new here, and learning a ton from reading older posts, as well as reading the Ashby reports.

        I shoot a longbow (not sure what it is, but remember it’s a Martin, but all make and model info was replaced by the bowyer who re-worked it for me). It’s about 63# @ 28, and I have a 28″ draw. It also has about a 1/2″ arrow shelf. I still want to weigh it to get the exact weight, but in the mean time, I’m doing reasearch on setting up an arrow.

        I’m planning on using carbons for the first time, after having used wood exclusively. However, in the Reports, carbon is the best for an EFOC arrow setup. I’m looking to get a roughly 800gr elkpoker with 25% or better EFOC.

        My qustion is: would it be better to go with a lighter shaft and heavy head setup (BH, inserts, adaptors, etc.)? I’m just not sure if I can get that weight with a ligher shaft without weight tubes, which would defeat the purpose.

        Thanks all, Rich.

          I’m rather “new” HERE, but old elsewhere.

          I’ve had the good fortune of periods of email exchanges and a few call contacts with the good doctor on EFOC.

          He and I chuckled a lament…that we used to “BUG” the arrow (carbon) companies to give us heavier shafts, now that we’ve discovered the benefits of EFOC, we want lighter, stiff shafts so we can front load without getting rebar weight arrows.

          I’d say from that, find the lighter shafts and load the front. EFOC is about front weight %… high 20% (28 and up) or over 30%, not the total weight as much.

          I started finding and using lighter overall weight arrows but they had thinner wall thickness to get lighter. Often they’re marketed as target arrows. I then followed Doc and Troy B’s suggestions and started over-footing with aluming sleeves about 2″ long. Bit of an investment, but hit a few ugly things (rocks, etc) with those type set ups and did nothing but flattened the field points.

          I’ve even sprayed them black to match my black arrows.

          It really helped strengthen that weaker impact area to use an aluminum over-footing, FWIW.

          Good luck and have fun on the journey!

            Doc,

            Thanks for the reply. I was thinking along the lines of what you had mentioned. I was going to start tuning today, but my bow string broke, so I guess it waits till I get a replacement, since I’m not making my own….yet.

            Thanks again Doc. I’ll keep you posted on my results.

              Rich, I’ve had a play with some lighter shafts like gold tip trads and easton equivalents. With a really heavy head and one piece adaptor/insert you might be looking around the 400grain mark for the head. If your shaft is in the 10-11 grain per inch range then you’re likely to land around 700 grains total, but with an FOC around 30% depending how long your shaft is.

              You could increase that point weight by having a heavy head on a heavy steel adaptor screwed into a heavy brass insert which could get you up around 800 grains OR you could use a heavier shaft that will increase total weight but reduce your FOC. Nothing comes for free unfortunately and it may require a little experimenting on your part to settle on something you’re happy with.

              I don’t feel like I’ve helped that much but maybe laid things out for you a little.

              Good luck 😀

                Rich, The Gold Tip Ultralight Entrada 300 is 8.5 gpi. I think that arrow may work to meet your objectives. You use the heavy broadheads, insert, etc. like you mentioned then use external footings to fine tune the arrow to your bow as well as fine tune the weight your looking for. You never know what the final answer will be due to sooo many choices to make in arrow components as well as the unique characteristics of your bow.

                Doc Nock, didn’t you and I discuss external footings and UEFOC in great detail several years ago?

                  As I live and breathe…you live!

                  You fell off the planet and then your email quit working.

                  Yes, indeed. You provided me with great tutoring on external footings! Pictures to boot. I’ve shared that information with countless others over the years!

                  So good to reconnect! Much has happened in those intervening years!

                  Email me sometime and catch me up on your end!:lol:
