I am no expert on Wharfedale presses or any press for that matter. Most manually fed cylinder presses I have encountered have an impression trip near the operator position.
I believe Clint Harvey in Australia (bp username: clintharvey) has one, you may try to reach out to him and ask specific questions about that press.
From memory the the impression trip is to the right of the cylinder when you are standing in front of the cylinder. I believe when the cylinder is at rest you should be able to release the tail of the packing then trip the cylinder and turn the press to get the cylinder to turn. Bring the gripper to the top and when the grippers are in the open position you should be able to change the tympan. I will check my instruction guide later in the week to confirm.
It’s fifty years ago since I last changed the packiĆg on a wharfedale, but could still change the packing of a Miehle in my sleep!!
thanks guys I have tried the impression feed handle and that only seems to work when its running does not work when you turn over by hand, but I will keep trying thanks to you all
Derek, You will probably find that the system comes into the *Fail Safe* option. i.e. for safety sake, when the M/c. is turned over by hand, the Imp. lever has to be held in at the same time, until the cylinder begins it`s cycle, implying **second** pair of hands.
Good Luck. Mick.
about 5 years ago I sent scanned images for one of these to member lishii if you contact him through Briar press he may still have them, it was a parts book, not sure now if it had how to change the blade
Derek,
Have you managed to engage the Wharfedale cylinder yet when turning over by hand? Thinking back 40+ years we had powered inching facility then so had no need to turn by hand. Have looked in my notes but no mention of engaging cylinder by hand, sorry.

Do you have any photos of the press?

I know this is a long shot but does anyone have any info on blade changing on a 1957 perfecta guillotine??
