Shop press build!

admin

Gday all, i have a quick question for everyone.Im soon to be undertaking the build of a custom shop press for my shed but having looked at pretty much every home made shop presses they all use c-channel as the uprights.My question is will there be any downside to using RHS as the uprights, i have some leftover 100mmX100mmX9mm but thought id better ask here first as to the practicality of using it or if its even a very smart idea at all.
Reply:I don't know exactly what RHS is, I googled it and found lots of tubing - I know the terminology is different on your side of the pond. I've heard multiple times that tubing takes alot of the spring out of it, making it more rigid.http://talk.newagtalk.com/forums/thr...ed&setCookie=1There's a press that's tubing and plate. I love this design, have talked to the builder/poster a fair bit and he's quite happy with it.Bruce
Reply:I shouldve actually said SHS, but that probably wouldntve made anymore sense to you either haha! RHS is "rectangular hollow section" SHS is "square hollow section" also reffered to as "box section" but essentially its just square tubing! But yeah do you think the 100x100 would be suitable and sufficient, i rekon the 9mm wall thickness of it should be pretty beefy, im only really planning on using a 12tonne cylinder, unless something bigger comes along at the right price! I will most likely be using 150PFC (parralel flanged channel aka c-section) as the horizontal components
Reply:RHS is rectangular hollow section (although can also be square) square tubing might be what you yanks call it.That RHS seems like it would be fine for the job, I used 100mm channel for my 20 tonne press when I made it because I scored some for free. Your RHS would be way stronger than what I used.Cheers AndrewWIA 270amp Mig Transtig 200 AC/DC Tig/stickHypertherm PM45
