Given that the valve assembly will be in contact with hp steam, which grade of Loctite would the team suggest?

Satisfactory working of the Don Young combined Vacuum/Steam brake as shown on Sheet 11 for his 5”G Black Five is dependent upon achieving a tight fit between the valve spindle and disc making up the steam brake valve. As drawn, this is achieved by means of a 5BA screw thread (see drawing) but I am having great difficulty in achieving a tight fit into the threaded disc. One option might be to use a high temperature/steam resisting grade of Loctite or something similar or, to resort to putting in a few indentations from the reverse side between the spindle and disc using a centre pop However, before doing so I wondered if there might be any other possible alternative solutions to the problem.

Martin - Problem now resolved using the polar array command.

DC31K - Yes, have also had success selecting the OSNAP NODE option

Many thanks guys.It is a very helpful forum.

Hi - I am having problems in drawing up a set of holes on a PCD using Autocad 2000. Having successfully DIVided the circle into the required number of divisions I was expecting to be able to ‘snap’ onto the division points to draw the required circle of holes but have discovered that OSNAP settings options does not seem to recognise the DDPTYPE markers inserted using the DIV command. Can someone please explain where I might be going wrong.

Has anyone carried out any similar power consumption checks for a Myford S7 when left running at idling speeds? Sorry but can't supply any details on the SP motor to reveal the model/reference number details as this would involve moving the whole ensemble away from the wall and that is a no-no at the moment.

I have always found it difficult to light my Sievert 871901 Light Line Propane Burner, the problem being that without covering the air holes at rear of the burner the rush of the incoming gas extinguishes the igniting flame. The answer has been to roll up a sliding brass sleeve to cover up the air holes for igniting purposes and then to slide it back to expose the holes once the gas stream is alight. No claims to originality but it might just be new to someone and it has certainly has answered my problem. The attached pics shows the sleeve in operation.

I have not used Hermes since they changed their name to ENRI but it would appear that they no longer accept Paypal as a means of payment. If this is the case and I would prefer to use a courier who does offer this method payment can anyone recommend some possible alternative services.

Use sharp drills and reduced speeds when drilling phosphor bronze..............

Many thanks to all who have responded to my request for some design detail. I am now in the process of making up my own version based upon the ideas shown here.

Hi Bill - Yes, it is the Chronos unit (or one very much like it) I have tried using to hold an hacksaw blade but the blade is not a comfortable fit and I was hoping for something better.

Hi all - I have been experimenting with using conventional 1/2"W x 0.025"Thk hacksaw blades for use as a parting off tool with the principal aim of being able to put in a narrow run-out/undercut in various brass steam fittings currently under construction. Problem is finding a design of tool holder suitable for holding a hacksaw blade given that the one I use for the standard Eclipse type parting off blade is not really suitable for the job. Can anyone recommend any more suitable designs for the holder?

.Having just completed a job on the lathe which involved turning followed by a cross drilling exercise reminded me of the old pearl of wisdom about keeping the piece part on the stock for as long as possible and to leave parting off as the final operation. Never a truer word was spoken

I have two pairs of 123 blocks in my stock which I have never had much use for largely beacuse 1) they are not obviously 1-2-3 by design (metric or imperial), 2) they only have holes drilled through from the front face and not from the edge and 3) None of the through holes are threaded. Do they have any potential use as 1-2-3 blocks?

Have attached a couple of recent pics of an early lift installation seen in a hotel on the south coast manufactured by the same George Bennie who constructed the monorail.

Thanks Martin, problem now resolved.

Thanks for that but perhaps you can tell me how to set limits in Trueview.

I am using Autodesk DWG Truview to print selected views of drawings created in an old (2000) version of AutoCad. The technique adopted is to open the drawing file in Truview, use PAN to select the part of the display required to be printed followed by Zoom Extents to hopefully fill the view with an image of the required size. The problem I am finding however that the sensitivity of the Zoom Extents function as currently set is too coarse with the result that I cannot obtain the final degree of ‘tuning’ to give the required view, the image appearing on the screen being either too small or too large to make optimum use of the A4 paper size. Can anyone suggest how this problem may be overcome?

Spelling error - I think the name of the fluid should read EOLYS

I have just had my PEF additive reservoir replaced on my diesel SUV and was amazed to be charged £128 + VAT for a litre of EOYLS fluid to fill the new tank. Naming no names of course but a quick search on the internet would suggest that a litre of the stuff can be purchased for something around £40 and so I would like to know what is going on here. Before taking it up with my garage I would be interested to hear if anyone else has had any simlar experiences to draw upon.

Well, despite all the doom and gloom and with absolutely nothing to lose I gave it a go using the Dremel with the tap indexed in the lathe and have achieved a useful compromise, the test nut running quite happily up the modified tap.
