Hi, Thank you gentlemen, that encourages me to try to think of some more useful ideas. ;D Martin

Hi Bogstandard, Thanks for the advice. :) I appreciate that tapping heads are not very good in blind holes so a tapping stand is most likely the best way to go. Sigh... Something else to add to the ever growing list. ;) That's the trouble with Model Engineering, there is always another...

Hi Guys, Thanks for the advice. ;D I think the final word is that I need a more expensive tapping head, one with an adjustable clutch especially when using it with smaller tap sizes. :o I have a reasonable amount of tapping to do on the cylinders to hold the steam chests using 7BA screws so...

Hi Noitoen, Mine works in the same way but I am not happy with the bite of the clutch as I believe for smaller taps it operates the clutch too late and will drive the tap to far in. I agree that reversing the tap requires the drill to lift the device to cause it to reverse but that action is...

Hi Folks, I have a Vertex Tapping Head, the 2 - 8mm version to use in a pillar drill. The clutch mechanism appears to be a bit too fierce in action, especially with small taps. :o That makes it keep driving when it would be better to reverse so is there anyway to adjust the clutch? I haven't...

Hi Chuck, I went for the deluxe version in imperial. Yours looks good. :) I made all the attachments as shown in the book and now need to make the drill sharpening device from the sharpening book. That is when I get a minute from wiring up my wife's dolls house. ::) In the pipeline is a new...

Hi Folks, I hope this may be a useful addition to milling machines. ::) I had to mill out a rectangle of steel to make a steam chest but I found that the backwards and forwards motion to cut the slots was tedious and difficult as with a flood of coolant it was not easy to see when the end of...

Hi Tel, Thanks very much for that, I'll get the book. ;D Martin

Hi Folks, Having built Harold's grinding rest, the more complex one, I noticed that there is an accessory for sharpening drills. Can some kind soul tell me where to find the plans for that? Thanks, Martin

Hi, Has anyone tried solid carbide drills in a dremel or similar to drill the main part of the tap out? Martin

Hi Jason, Thanks for the advice, I'll take that and follow it. ;D It will be a long time before I need to worry regarding the tractive effort but I am getting there very slowly. ::) Martin

Hi Guys, Thanks for the advice. ;D I think that given what you have both said that it would be a good idea to lag the cylinders and use a superheater. Avoiding loosing steam is vital in this build as there is a problem with the small boiler model in that it is prone to run out of steam early...

Hi Dave, The answers are, I am not that far forward yet but I will assume that I will include a superheater. So I would be best to go with a high temperature insulation or as you suggest just air. ;D Thanks again for the advice. Martin

Hi Dave, OK, a waist it is then. ::) What material do you suggest for the insulation? Thanks, Martin

Hi Jeff, Great! Thanks for the reply. It will be easier not to mill a waist in the cylinder then cover it with sheet. ;D I can just cover with sheet anyway for appearance sake, then polish it... Arnak

Hi Folks, I am fabricating the stem cylinders for my 3.5" Virginia out of Cast Iron however I noticed on the plans that the cylinders are shown with a 3/32" curved waist between the two ends. Is this just decorative or to save material when casting? ??? I ask as most of the pictures I have...

Hi, Yes that is true, even with the rack secured there is still a couple of inches swing from side to side when raising or lowering the head. However it does stop the violent head swinging when raising or lowering which I found to be a pain. >:( Just a thought but I suspect the only real cure...

Hi Folks, Just a quick tip for those who have mills with a round column like the Warco Major Mill. It can be a problem when raising or lowering the mill head to stop the head from swivelling around the column I used 2 cap head bolts to secure the rack to the column, as per the picture, one at...

Hi Captain Jerry, You've had plenty of advice on how to remove the bolt but here's some to stop him doing it in the first place. ;) First, tell him that you are not going to help him the next time he uses an adjustable wrench! *club* You will need to stick to that threat as if each time he...
