Robert Miller: by the way how long are your limbs on this bow?
Robert Miller: also how do you string this bow completely from start to finish?
Banay Waldo: now that you have 3d printer you can make really good cams
Robert Miller: also how did you attach the string to the out side of the cams or did you
finaly attach them to the out side of the limbs?
Robert Miller: thank you also like I said if you call the spots mans guide they carry
Kevlar cord in 25 foot lengths and sell it three for $13.49 which will come
to 75 feet I am ordering to lots like that and it is very low stretch also.
Robert Miller: by the way what is the diameter of your cams and how far in did you drill
the holes for the axels also I have an idea to prevent that string slip
that you had also I found a good source for string material and you can get
it from sports man guide it is Kevlar cord the number is 1-800-888-3006 it
is in their shooting catalog.
Robert Yasumura: Loved the video. I've watched a few of your videos and my only complaint
is the photography. You're back-lit a lot, so I can't see clearly what
you're doing. I would also gently suggest that you be careful of drastic
light changes, like shadows on a bright day. The camera can't handle it
well, and so anything in shade is lost. Great work.
Robert Miller: by the way I have a suggestion for other builders if installing sights on
the bows and if looking for a good sight light to light up the pins for low
light use I have found a very good source that is also cheap it is the
party finger lights that are sold in three packs at a local family dollar
or similar place. they are only a dollar an light up the pin sight very
nicely if interested and are very lite in weight.
Robert Miller: thank you i am in the process of building a compound bow i cheated on the
cam thoe and bought one. I am flattening the whole limb tube but I am also
placing fiber glass rods inside of the limbs and trying to bend the tube
around the rod but in such way as it will be butted up against the rod ends
inside the limb tubes for both strength and power but still having problem
with idler wheel, can you give me any suggestions?
Robert Miller: hi again I have a question. can pvc be heated up enough to be bent around a
3/16 rod so that an axel hole can be formed and then epoxied in that
position with out cutting or drilling so that It does not lose strength for
using in the limbs of a diy compound bow? for instance the last two to
three inches flattened and then folded over said rod so that rod is 90
degrees to the pvc limb tube so it is like an axel for the cams ans or
idler wheel please get back to me and let me know also if you are
interested in compareing ideas further and if interested in talking 1on1 my
e-mail and messenger firstname.lastname@example.org I would greatly enjoy hearing
from you on this matter.
Robert Miller: also i would greatly love to see complete build along videos on both this
bow and other compound bows that you have made also on the experimental
super short bow my wife likes the way it looks and is wondering if you have
a complete build along for it and had an idea for it if possible if you
made the riser a little longer is there any way that you could add tha same
kind of sights like what you have on the larger compound bow that you made
completely out of pvc also we were both wondering what the poundage was on
the draw weight of the super short bow possibly for hunting as a survival
bow for a back pack or truck bow just a thought or even a super short bow
in a tree stand. would realy like to hear your thoughts on this.
Robert Miller: I am wondering how you attached your cables to your cam and also how you
fixed the problem of cam lean I mean after you fixed the problem of the
slipping and how you fixed that too?
Robert Miller: i wish that not only would you show how both of the cams are made, but also
how they are strung completely. I am a big fan of this site and I have some
ideas for improvements for instance instead of using 1/4-20 threaded rod
how about using 3/8 or 1/4 inch strait rod and using sealed bearings in the
cams and if possible idler wheel on your other bow also on your all pvc
compound would you be able to do a built up riser handle simular to the one
on the recurve with your special limbs? it is just a thought also instead
of tapping the ends of the axle rods for nuts why not just drill and use
either cotter pins or r-keys to hold the axles in place with both washers
and spacersfor the strings?
JaycubL: That how-to video us up! If you are interested it is here:
JaycubL: Probably, you'll have to try it!
gregGRW: Great work man :)
Downsouthgaming: I´m impressed, superb job! I have been shooting recuve and longbow since I
was a kid. And Ive just finished my 50th bow. So now is the time for a
compound! Just wanna let you know YOU inspirred me to build it! Wish me
luck:) Best regards from Denmark.
varun009: did you not watch the video?
JaycubL: I think something like 12-15 feet, I get the impression you might be making
a similar bow?
JaycubL: I have it set up for 3 strings now and it needs a little more work so I
could record the things you asked for. Another thing you may be interested
is a compound bow I am working on that is made to be like a home made
version of the "liberty bow." It ts made of cast aluminum everything and
Leif Pikkarainen: No the cylinders were an overpowered vesion of of an airguns pistons
antonfoxity: this isn't a compound bow u mooron a compound bow has cams
JaycubL: I am holding a drawing for a free 50lb PVC takedown bow, if anyone would
like to get their name in the drawing see my video for details:
Leif Pikkarainen: Hmmm seems like a nice bow. You should go deer hunting lol. Btw i like your
videos they are epic bro.
UncleFexxer: Nice! That riser's a really sweet bit of woodwork.
byalexandr: How much did it cost to make this?
Robert Steele: Great job. I love to see people using their brains to make things out of
nonstandard materials. Keep up the great work!!
JaycubL: Thank you! That means a lot coming from such a well known bowyer! I have
learned a lot from your videos and of course have made my own improvements
to the process. I might post a video of the way I make PVC recurves it as a
response to one of your videos.
px223: i wanted to do one like this but failed numbers times , now i have some new
idea , thanks
batfrog1: Excelent work! I love to see people using their heads.i've been working on
a similar bow, made from red oak.
JaycubL: Yes as I have said several times now including in the video, the string was
slipping where it is fixed to the cam on the first draw, and reducing the
draw weight from then on. I changed the way it was strung up and it can not
slip like that now because it is three separate strings. Kind of hard to
explain. I am almost done with a how-to vid on making a different type of
PVC compound bow, so maybe I will test this bow's real weight at the end of
JaycubL: Thanks! I'm glad to help your argument. You should show them this video and
some of BackyardBowyer's stuff. I've got this strung up properly now, and
while I haven't tested the draw weight it now feels more like 60-65# (it's
strung tighter) and has a huge letoff percentage. I don't think the PVC
takes a set at all, like wood might. The main problems with PVC are that it
softens in hot weather and can be deteriorated by UV exposure.
Jieh47: I think he was talking about how much the bow weighs. Nice work though :)
byalexandr: Yes in fact, I just finished cutting the riser. Do you think I could put
3/4" PVC for the limbs? I want it to be about 25-30 lbs. of draw weight.
JaycubL: Um, if you realy want to buy this I would sell it to you for $70 +
shipping. It does not currently have a string on it because after sitting
with the string on it developed some cam lean. So I would need to make a
new string and make sure the cams are straight then I could sell it to you
if you want.
JaycubL: This has cams. Maybe you didn't see them because they are made of clear
acrylic. But if that happened you must have been really not looking.
JaycubL: In most of the shots in the video yes, as I said the string was sliding and
reducing performance a lot. That problem is fixed now. It is probably
50-60# peak weight now but only for a few inches in the draw (same as
before but only for one shot, now it stays that way). The brace height is
very high which reduces the total impulse too. One thing that is nice is
that it has a very high let-off which makes it easier to be accurate with
in my opinion than a non-coumpound bow.
JaycubL: See the response I gave to basically the same comment below (in reply to
wrxyluv). It says right in the first part of the video why!
JaycubL: You may be a very skilled craftsman, I don't know. But your comments saying
basically "oh your bow is so weak and useless" are offensive to me. So that
is why I replied in that way.
JaycubL: Springs in a cylinder? I am not sure what you mean. Do you mean that the
string was on wheels at the end of the limbs, and the wheels were spring
loaded to twist and pull the string forward?
JaycubL: OH I see, cool. That is a very original way to make a bow.
daveuk2012: or put it in the description..
Eduardo Peña: you have plans or drawings?
Tyler J: not 50lbs might be 17lbs
JaycubL: Thank you for your advice. I like it how it is though. I am not looking for
any more stiffness in the limbs, they could easily be remade as stiffer
limbs by using the same type of pipe but not flattening the middle. There
is a groove in the cam. It is the full width of the cam and is roughly
parabola shaped. I guess it is hard to notice because there is not a corner
in the center of the groove. The full-width groove makes it easier to get
the string to track if the cam is not perfectly straght.
Leif Pikkarainen: Instead of using cams a friend of mine used some springs from a mattress
inside of a cylinder it was a good bow. I dont think it was as good as this
kylemcgeever: I did not mean it was useless. I believe that all bows are either weapons
meant for killing, or more of a hobbyist type meant for fun. I cant see
your bow killing an animal, but if you did it would be truly badass.
WaWoWieWa: looks nice... between 5 and 10 lbs ?
wrxyluv: That is about 15 pound draw weight.
JaycubL: You are like the third person to say something like that. If you would read
the other comments (not to mention words on the screen in the first part of
the video) before commenting you would know why most of the shots in this
video were at like 15# draw weight.
Chef de NYC: Thanks! I'm more info ultrasound type of work. I learn most of the stuff myself online. Just only recently start looking for a school to make things "official". Hehe
