Flaky234 Posted March 2, 2013 Posted March 2, 2013 Hi,I want to know if this press is suitable for all types of rockets: http://www.ebay.at/itm/Hydraulische-Werkstattpresse-6-ton-Hydraulikpresse-Lagerpresse-Dornpresse-/360606686208?pt=Industriemaschinen&hash=item53f5d55c00#ht_2979wt_1139 Thanks for your awnsers!
nater Posted March 2, 2013 Posted March 2, 2013 With that press, you are limited on the working length. You'll need room for the longest motor you plan on pressing, plus extra for the rammers, a PtoF gauge (or tap the jack for one). A 6 ton jack may not be enough either, since it can be difficult to squeak the full force out of them without straining yourself. If there is room for the motors you want to press. Also keep in mind to plan for the largest size you want to build, then get one even bigger. You wouldn't want to buy a press that limits you to 1 pound motors and kick yourself after you just have to build a bigger one.
Flaky234 Posted March 2, 2013 Author Posted March 2, 2013 Hi,thanks for your answers. I will buy this one because it only costs a little more and an it is alot larger: http://www.ebay.at/itm/Hydraulische-Werkstattpresse-12t-Hydraulikpresse-Lagerpresse-Dornpresse-12-to-/310605871678?pt=Hebe_Hydrauliktechnik&hash=item48518d7a3e#ht_824wt_1163 ! Do you think this will be good? Also how to install the gauge?? Thanks
nater Posted March 2, 2013 Posted March 2, 2013 (edited) A lot of people use that press or a clone of it. Some have found the frame twists a bit with high pressure and add straps on the back to strengthen it. Dan Creagan's site is an excellent resource for tips. http://www.wichitabuggywhip.com/fireworks/rockets/presses.html He also has instructions to add a gauge to the jack. http://www.wichitabuggywhip.com/fireworks/tapajack/tapajack.html Edited March 2, 2013 by nater
Flaky234 Posted March 3, 2013 Author Posted March 3, 2013 Can I use a press without a gauge for pressing rockets? Because I can't install a gauge without messing it up and when I buy a press with a gauge it costs >300€........ Thanks
Col Posted March 3, 2013 Posted March 3, 2013 A gauge is very useful for consistancy, you could easily go overboard with the pressure using a 12T press without realising it.If you can find a cheap short bodied ram you can make a P-to-F gauge very easily. They look like this:http://www.ebay.at/itm/10t-Hydraulikzylinder-Kurzhubzylinder-max-11mm-Kolbenweg-hydraulic-short-ram-/150966825437?pt=Hydraulik_Zubeh%C3%B6r&hash=item232652f1dd
nater Posted March 3, 2013 Posted March 3, 2013 Some sort of gauge is very important for pressing rockets. The two most important things for a successful motor are consistent and small increments.
Flaky234 Posted March 3, 2013 Author Posted March 3, 2013 Ok thanks,I for sure will mess up the press while installing the gause..... What press are you useing? Thanks
nater Posted March 3, 2013 Posted March 3, 2013 I made my own press, to meet most of my wants and needs from the tool. http://www.amateurpyro.com/forums/topic/7292-semi-portable-press/page__fromsearch__1
Flaky234 Posted March 3, 2013 Author Posted March 3, 2013 Whats that thing between the jack and the tooling?? Thanks^^
AlexPyro66 Posted March 3, 2013 Posted March 3, 2013 Whats that thing between the jack and the tooling?? Thanks^^There is a P2F gauge and some steell plates
Shadowcat1969 Posted March 4, 2013 Posted March 4, 2013 Here's a tutorial on making your own PtoF guage: http://www.skylighter.com/fireworks/arbor-press-force-gauge.asp
