|Thread: Who makes miniature imperial combination or open end spanners ?|
Amazon list quite a range of BA spanners in a number of different styles including open ended , combination and box spanners.
|Thread: ET Westbury flash boiler|
For your information , this drawing is shown as fig 5.2 in the Benson book which I am about to put on sale. On page 69 of the same book fig 5.8 shows a design for an ETW diffused flame burner which may be suitable. Suggest you may find it useful if you could get to talk with Phil Abbott of the Blackheath Model Boat Club. Believe he also may still be the straight running secretary of the MPBA. Contact may be possible via our companion Model Boats web site ? Certainly Ive always found him to be a very helpful and knowledgable chap on the subject of flash steam. With respect to certification of the boiler, I would assume it would depend upon its bar-litre capacity , a point which I am sure Phil or any MPBA club boiler inspector would be able to clarify.
|Thread: Storage - How to?|
I had exactly the same problem with the smaller set of Bisleys shown in your pic. My solution was to obtain some reject (4mm) strip wood from my local DIY , and then to ceate different sized egg boxes in each drawer. Because I have a low manual skill level , all half housings were cut on the miller with a slot drill. Bases of drawers were lined with hardboard and then ecause of the return edges on the drawer sides , the crosspieces were dressed on their top edges so as to be a firm fit under these return edges before being positioned as appropriate. The longditudinal pieces were then slotted into place , with the half housings held together with a strong water-proof wood glue. This arrangement has worked well for me for almost 5 years.
|Thread: Welding/brazing tips.. Propane vs Acetylene|
Have you tried asking an equipment supplier such as BOC Australia ? For my part , I have always found their UK branches to be most helpful in heping with my gas querries.
Working in such a relatively small niche' market , I have no doubt that suppliers such as Chronos (no connection) are working on tight profit margins , and so maybe do not have the money to throw at a first class stock control system . And , just by way of putting things into perspective , during a recent visit to London in November 2013 , I really pushed the boat out and bought a tube of Harrods own brand biscuits from their store . I later decided I would like some more (!!) and so emailed all the packet information to Harrods requesting details for further supply. The reply I got literally took my breath away. In effect they do not have an effective stock control system , and suggested I should travel ( 350 mile round trip !) to the store to check for myself ! Now , given their situation , if they cant be ....... to install such a system , how can we reasonbly expect the likes of Chronos to do so ? A copy of the email is available to anyone interested.
May I suggest you search Myford Lathe Service from 14/10/2011 in this Forum section. There you will find references and contact details for Darren and Pete who are ex-Myford employees and whom I am sure you will find most helpful and would heartily recommend both . I have no connection with either of them , other than as a satisfied customer of both.
I hope you will find this information of use.
|Thread: Myford Saddle hand wheel dial|
When I purchased my reconditioned S7B from Myfords, it came with one of Graham's dials fitted , and as far as I am concerned, it is an excellent and indispensible piece of equipment . In actual fact , it was because of the dial that I chose this machine in preference to the other similar ones available at the time .

|Thread: Chemistry question|
Appreciate we are probably only talking about small amounts of gas here , and the risk of an untold occurance is therefore low , but would still like to supplement the excellent information and guidance already offered. Think your decision to work with an open door is a most prudent one . Regarding the hydrogen , please note that IT burns with an invisible flame , which is why we were instructed to approach a suspected hydrogen fire with an outstreched roll of paper so that it would act as an indicator. With respect to the nitric oxide ( nitogen monoxide ) , please note this really can be rather naughty. It is an oxidiser , corrosive to the respiratory duct , and can also cause severe skin burns as well as eye damage . And then , just by way of a bonus, it can cause / intensify a fire. Given all these issues , I believe good and consistant ventilation to be an essential requirement. Just by way of a small additional piece of information , at work we were unusual in that we had a fully piped nitric oxide system ( arranged in 2 x 4 banks of equivalent J size cylinders) feeding into the neonatal critical care unit . For a number of reasons its use was discontinued and we reverted back to the original very small cylinders.

|Thread: 3" allchin trunk guide casting|
I think you will find that John Rex Model Engineers on 01977 699669 or firstname.lastname@example.org produce the drawings and castings for the 3" Alchin.
Hope this information is of use.
|Thread: Need a bit of Motor Advice.|
For your information , and as an alternative to Ebay , Axminster Power tools do 2 NVR switches which you may find of interest ; part no 600072, rated up to 2Kw for £11.45 and also the other, part no 340181 , rated up to 1.5Kw for £15.95. I have had one of the latter for a number of years used for swiching a cutting-oil pump and it is sited under the front of my lathe drip tray, so far without problem.
Hope this helps.

Got some Sifbronze No 1 rods available and you are welcome to some foc if you think they may be of use. If so , please send me a PM and I will post.
|Thread: K1 chuck key for a Jacobs 1A chuck|
According to my 2008 edition of Cromwell Tools catalogue, the K1 key suits all Jacobs series 1 chucks and is Cromwells reference number S7 . The.ir order code is KEN-441-0140K , and was priced at £1.76 +VAT in 2008.
Hope this helps.
|Thread: model carry/storage box|
Think you may be interested in talking to Moducarry on 01744 886105 or www.moducarry.com . Saw them at a model boat show where they were showing a range of plywood based padded carrying cases. Understand they also produce custom made cases.
|Thread: Vertical boiler design|
I have some excellent copies of Model Boilers and Boilermaking by Harris , at least one of which I believe is hardbacked , which I was going to put on fleabay. Will try and establish a fair price over the next couple of days and will post for your consideration.
|Thread: 3/8 BSF 1/2 long grubscrews|
May I suggest you try your local Cromwell Tools branch who list these as Socket Set Screws with Knurled Cup Point under part number CTL - 603 - 2728A at an offer price of £60.44 + VAT per 100 in my 2008 catalogue. In the past I have found them oust helpful and understanding in supplying smaller amounts. Hope this info helps.
|Thread: Winter Project|
Just had a look at the plans, and believe the cylinders may originally have been castings, but since they are only 1 1/4" long , they would be easy to make from solid or to fabricate. Assume the wheels were the only other castings. Hope this helps.
|Thread: LBSC Pamela Information|
Believe the plans from MHS are reference LO 73 and the articleswere in M E Vols 102 - 104 . Hope this info helps.
|Thread: Winter Project|
Perhaps you may find the 3 sheet set of plans for a G1 Diana I presently have for sale on an auction site ( item reference 200980706299 ) of passing interest.
|Thread: Sharpening Milling cutters|
