Flaky234 Posted March 2, 2013 Share 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 Share 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. Link to comment Share on other sites More sharing options...
Flaky234 Posted March 2, 2013 Author Share 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 !

nater Posted March 2, 2013 Share 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 Link to comment Share on other sites More sharing options...
Flaky234 Posted March 3, 2013 Author Share 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 Link to comment Share on other sites More sharing options...
Col Posted March 3, 2013 Share 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 Link to comment Share on other sites More sharing options...
nater Posted March 3, 2013 Share 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. Link to comment Share on other sites More sharing options...
