Col Posted January 11, 2018 Posted January 11, 2018 Liking the plywood gears but not much to go on from the peek
OldMarine Posted January 11, 2018 Posted January 11, 2018 Someone here had a shell paster using plywood gears that was a work of art but I can't find it now.
pyropro Posted January 11, 2018 Author Posted January 11, 2018 lol yeah I saw Cols on YT nice machinemore new pics
starxplor Posted January 12, 2018 Posted January 12, 2018 First two pics show thumbnail in your message but fail to load when clicked on. When the third one is clicked and loaded, it acts like the only one with no nav arrows to go back to the other two.
Mumbles Posted January 12, 2018 Posted January 12, 2018 Fixed it. I've never seen this happen before, but the first two were the same exact attachment. Apparently having the same attachment in a post twice makes the software get hung up. 1
pyropro Posted January 13, 2018 Author Posted January 13, 2018 Thanks all soon done waiting on one part.If you are at all interested let me know first 5 are sold and as it stands takes about a week to make. 1
Col Posted January 14, 2018 Posted January 14, 2018 Looking forward to seeing a pic of it fully assembled
pyropro Posted January 15, 2018 Author Posted January 15, 2018 soon very soon.I will email you where to see the video.Jeff
Arthur Posted January 21, 2018 Posted January 21, 2018 (edited) Am I right in guessing that the Pyropro pasting machine has a fixed angle between the shell holder and the tape applicator? This would certainly create a rugby ball shaped shell which may not fly optimally. As an aside; I heard a little while ago that Stanley the tool makers offer a steel tape measure with feet and inches marked on the usual side but with the other side marked with pi x feet. Supposedly to let loggers determine the diameter of a trunk by measuring it's circumference. Now having seen wasp users trying to calculate how big the shell was from it's circumference, one of these measures would solve that problem instantly.

Col Posted January 21, 2018 Posted January 21, 2018 A fixed angle is ok for smaller shells, the shape is more like a barrel than a rugby ball. For larger shells its better to use a magnet and multi axis pasting. If you paste one axis at a time on a load of shells they get chance to dry before the next axis is pasted. As long as you remember to mark where the poles are/were its pretty easy to keep track. Some homemade machines offer manual angle changes during pasting but not many alter the shell rotation speed along with the angle.

Col, Thats a most excellent example of a "Picture is worth a thousand words"! Kurt 1
pyropro Posted January 21, 2018 Author Posted January 21, 2018 The one pictured here will have two angles to wrap,maunually!!
Col Posted January 21, 2018 Posted January 21, 2018 Looks like you`d need to remove the shell to change the angle.
pyropro Posted January 22, 2018 Author Posted January 22, 2018 yes,keep in mind the size of this machine(take it anywhere with no dependancy on electricity) and the fact that its cost is only $299.00!!!!!!!!!!!!!!!!!None on the market can come close,if there is one.
Col Posted January 22, 2018 Posted January 22, 2018 If the shell rotation is driven by a gear motor its dependant on electricity
pyropro Posted January 22, 2018 Author Posted January 22, 2018 (edited) Col,always splitting hairs arent we.Portable electricity is a more accurate description indeed.As in 6 volt. Edited January 22, 2018 by pyropro
Col Posted January 22, 2018 Posted January 22, 2018 How is it splitting hairs? You said you can..take it anywhere with no dependancy on electricity.I guess batteries are (literally) not included
pyropro Posted January 26, 2018 Author Posted January 26, 2018 (edited) Why would I include batteries ? Ever mailed anything like batteries?They are not allowed.Out of the five sold if life gets out of my way to finish this build four are going over seas. No way would I even try to put a battery in the package to be rejected at customs. A typical 6 volt is only three bucks in in the states. I hope I havent offended you Col you know I cant tell a lie.

Col Posted January 26, 2018 Posted January 26, 2018 (edited) If i bought something that was reliant on batteries, i`d find it useful to know how long the battery would last. especially if i planned to use it in a field. The drain on the battery will increase with shell size and tape width. The load increase or the battery running down will effect the shell rotation speed. You seem to have designed a machine that makes life harder for the end user Here`s an idea of the manual cranking speeds needed for different shells based on a shell motor speed of 1 rpm.These are with 1/2" tape: 1.5" 17rpm, 1.75" 19rpm, 2" 21-22rpm, 2.5" 26rpm, 3" 32-33rpmSwitching to 3/4" tape: 4" 28-29rpm, 5" 38rpm. Switching to 1" tape: 6" 34-35rpm.I had a go with mine and its not easy, i think an adjustable metronome may be the way to go https://www.flutetunes.com/metronome/ Edited January 27, 2018 by Col
