Hi Brian, It may be worth while designing the steel rim of the flywheel to be consistent with the dimensions of say schedule 80 pipe. 3 1/2" schedule 80 steel pipe has an OD of 4" and a wall thickness of 0.318" while 4" schedule 80 pipe has an OD of 4.5" and a wall thickness of...

Hi again Steve, If you open this Users Manual; https://drive.google.com/file/d/0By6GyjLhonZNRWR6UDVVUXduNG8/view and look on page 35, you can see the gears required to cut inch threads on a metric machine. Regards, Alan

Hi Steve, Looks like a quadrant and change gears for an EMCO V10P lathe. I had a metric one and I made a quadrant and the change gears so I could cut imperial threads. Of course your set could be to cut metric threads on an inch machine. Emco stuff was very expensive so it would...

Sorry, I forgot to say that the 5/8" section is held in a collet on the mill.

Hi, Here are some pictures of the holder I made for 22mm gear cutters. Sorry for the quality - my phone is not great at closeups. I made it by brazing a short length of 5/8" (16mm) steel to a piece of 1 1/4" (32mm) steel. The 22mm section which fits into the cutter needs to be strictly in...

Thanks for the link Charles. I've got an old chuck which is out of true. I couldn't work out how to put the jaws under pressure and still get access to the bore. Now I know how to do it! Cheers, Alan C.

Hi, Is there a video showing how this system works? I don't understand it. Must be getting too old. Alan C.

Hi, There is an interesting video by Keith Rucker on YouTube which shows how to drill through a broken tool steel tap or drill at the bottom of a hole. There have been numerous discussions here in the past about how to deal with this. The video is here...

Thanks Wizard and Mike. At least I know what they are called now. I'll try the local fastener suppliers tomorrow. Regards, Alan

Hi all, Thanks for the comments and suggestions. I tried cutting a slot and screwing the fastener out with no joy. The fasteners on my lathe seem to be made of aluminium with tapered shafts and are hammered in. I ended up using a 1/2" wood chisel as John suggested. The trick is to use...

Hi, I'm in the process of restoring an old lathe and I've got to the stage where I want to remove the name tags and data labels in preparation for painting. They are made of thin aluminium sheet appear to be held in place with round headed aluminium nails. There was one tag which was so...

Hi, As Harry was killed, he was presumably buried by the War Graves Commission. You can do a search here: http://www.cwgc.org/find-war-dead.aspx for his grave which can narrow down the candidates. You can also check military records here...

Wow. That is truly amazing. Any chance of a video of it running? Alan C.

Hi, You want to be careful the clock isn't deemed to be a national treasure and you are forbidden to export it when you are finished!

Hi John, How did you get on? Did you have any joy from the supplier? Regards, Alan

Flipping heck. I'm struggling to finish John Wildings weight driven wall clock. The amount of skill and work involved in your device is really mind blowing. Alan C.

Hi John, I guess there's not much doubt it's an electrical/electronic problem. Your best bet might be to go back to the supplier with the videos and get them to query Seig. I doubt your problem is unique and they should be able to identify what the problem is. Regards, Alan

Hi John, As you say the problem certainly sounds like it's mechanical. The source of the noise sounds like it could be associated with the cover on the left hand side of the machine (it sounds like something knocking on light gauge steel). There are a couple of things that can go...

Hi Chriske, Did you start with a plain disc with a flat edge or did you start with a groove with a diameter equal to the tapping drill size for an m6 thread? Regards, Alan C.

That engine is just unbelievable. I presume he has taken the measurements off a full size engine. There are some really clever people out there. Alan C.
