    Thiel Duplex 159 strip down.

    The grease usually used was a type of Kluber Isoflex but I'm not sure if that is still the best choice. A very small tube costs about GBP30; you may need more than one tube.

    Thiel Duplex 159 strip down.

    Just to be clear about the spindle bearings and what you need if you wish to do to replace them. Firstly you should familiarise yourself with the SKF 'Bearings in Machine Tools' book. This desribes in detail how the bearings in the spindle work and how to install and set the correct running...

    Thiel Duplex 159 strip down.

    It is fine to remove the entire spindle as an assembly. The difficult bit is if you decide to strip down the spindle cartridge. I would not do that unless you really need to and understand how to correctly set the bearings. It is not just a matter of putting it all back together.

    There are instructions for removing the spindles in the manual. Unless you know you have a problem with the spindle I would not dismantle it. If you do have problems you will need to do some preparation first and locate a source for the rather special bearings. This is not a casual job.

    Thiel Duplex 159 strip down.

    That would work fine. Another possibilty is a strong mag base. I suspect any problem the poster has may be due to old oil and general dirt.

    Thiel Duplex 159 strip down.

    Please see attached photos which may help you to remove the sprocket drive from the chain. The chain drive mounting plate on your mill will probably be painted, but when I removed mine years ago I decided to clean what remained of the paint from this part. After removing the three screws, you...

    Thiel Duplex 159 strip down.

    I replied to your private message before I read this message. I will investigate the chain drive mechanism on my mill with photos. My recollection is that the drive does just pull out, but your may be stuck. Anyway I should be able to get to this on Monday and will then post pictures.

    Anyone got an alignment test sheet?

    I just had a quick look and there seem to be plenty of PDFs on the internet if you have trouble getting hold of the real thing.

    Anyone got an alignment test sheet?

    I don't have a test report for a Deckel mill, but you may find what you want indirectly in the book 'Testing Machine Tools' by Georg Schlesinger . This certainly used to be the standard reference for machine tool testing and gives the tests that you should perform for various different types of...

    Hick Hargreaves Engines

    I would agree that the engine man would normally be on hand - barring engines require physical intervention to engage them, and would normally be closely observed. The only exception I can think of is a very large engine where the main steam valve is a long way away from the barring engine but...

    Hick Hargreaves Engines

    We have a collection of orphan barring engines at the museum. The Hick Hargreaves example (and all the rest of the barring engines) can be seen running (by request) on our steam days. We have two Musgrave barring engines. One of them is a twin cylinder 'boxer' unifow design. This is a most...

    Hick Hargreaves Engines

    Our Musgrave 'Non Dead Centre' (NDC) engine has the barring teeth in the middle of the flywheel but there are no additional teeth on the inside of the rim. I expect this was because this is a relatively small engine with no real need for a barring engine. The teeth that are provided are ideally...

    Hick Hargreaves Engines

    I think I can see some little lumps on the top of the goalpost frame that could be jets. On the right hand side there appear to be linked pipes going off into the background. Of course this might just be imagination on my part, but Tyrones's idea may well be correct. The flywheel is being...

    Hick Hargreaves Engines

    One of our volunteer team carried out 'outside' work like this for Hick Hargreaves. He fitted Titanium tubes to condensers all over UK, mostly in power generation. You may well have run into him. He has a lot of stories to tell about these jobs.

    Scrapped in 1971? - that is quite a good life for a designed in haste wartime built cargo ship. Great research to find the ship and photos!
