|Thread: 48dp Muffett spur gears wanted|
Be worth looking at SMD Direct as well **LINK** it looks as though they have a pretty comprehensive range and are priced individually. An internet search of 48dp gears throws up a lot of options as they are used in rc cars amongst other things.

|Thread: Can You Identify This Tool Post?|
Hi Felis, and welcome to the forum.
Your tool holder looks very much like the Chronos Engineering "Economy Quick Change Tool Post" as illustrated on the Chronos website ( **LINK** ). I've never seen or handled one in person so I can't help you with dimensions etc but if you measure your post up and contact Chronos after the holidays they should be able to tell you if it is one of theirs or if their tool holders will fit your post. It looks as though there are some detail differences so it's possible that the post that you have is a home brewed version rather than a commercial offering.
|Thread: Threading/change gear chart|
Chris the "official" list of gears for your lathe would be 2x20, 2x30, plus 1 off of each of the following 35, 38, 40, 45, 50, 55, 60, 65 and 1 off 63 to allow for "near enough" metric threads.
|Thread: Drummond lathe|
As Bazyle says above, but I've got a feeling that Picador "made" pulleys etc. as I think the company is no longer with us. Drive line components (pulleys, belts, plummer blocks etc ) are still readily available through various bearing suppliers. A quick on line search will turn up many options as well as second hand stuff coming up regularly on EBay.
Ray, the ex Yahoo Drummond group isn't hard to find, just follow this ***link*** (https://groups.io/g/drummondlathe)
|Thread: Chinese drip feed oilers|
Brian - I think the thread that you're struggling with is actually 1/8in BSP - the usual figure given for the od is 0.383 in. x 28 tpi. It's a fairly common thread, even my cheapo tap and die set included it.
|Thread: Help to identify Lathe|
Yep, Drummond M type.
For a LOT of info try the "email@example.com".
Once you've become a "member" you can access the files and you'll find a load of information about all of the Drummond manufactured lathes. As a "non-member" you should still be able to see the topics under discussion and get a feel for the depth of knowledge, friendliness and helpfulness of the rest of the group.
|Thread: facilitas 3.5 gauge|
Hi All, if you go to the following website - https://modelengineeringwebsite.com/Midlands_2015_2.html - and have a look at the thumbnails of the photos that come up. The 4th down on the right hand side should show you what Facilitas looks like.
|Thread: Rothenberger Super Fire 2 Torch|
Bullfinch also do a couple of bottle mounted torches. Not used one but the Bullfinch hose torches that I've got seem to be completely satisfactory.
|Thread: Protective film for polished metal.|
What about ordinary kitchen cling-film?
|Thread: Covid 19 and the DVLA|
I'm in much the same situation but if you look on the DVLA website there is a note that suggests that driving licences were given an automatic 11 months extension. My licence "expired" in October 2020 but I had very little problem with getting the use of a loan car - with insurance on the dealers policy, while my own car was being serviced, and the dealer DID check with their insurance company.
I believe that the problem with the eye tests is that some of the machines used for the field tests cannot be sanitised between examinations due to the effects of the sanitiser on the surface of the bowl. I arranged for an eye test with Boots last October and there was no problem, but they did not carry out the field test. Face masks and appropriate protective gear had to be worn by both the tester and the person being tested.
|Thread: What’s this tap? Thread form?|
|Thread: Any idea on what this item is?|
It looks as though there is a fiducial mark on the peg to the left of the worm bearing nearest the hand-wheel as well as the minutes markings on the worm shaft.
Having worked in an industrial R&D environment for 31 years I got quite used to seeing odd bits of equipment like this that were made up for special purposes where one or a few off measurements were needed and/or suitable ready built kit wasn't readily available. The mounting plate has again probably been re-purposed from some scrapped machine and just happened to be suitable for the job - pretty heavy and solid.
R&D scientists/engineers tend to be pretty resourceful when they need to be and re-purposing odd bits of kit was part of the fun.
|Thread: Odd size allthread availability?|
I think you'll struggle. In Kempes Engineers Year Book for 1965 7/32 BSF is marked up as "to be dispensed with whenever possible". So if it was out of favour 55 years ago it's not likely to be stocked very much. The common sizes of 3/16, 1/4 and 5/16 are readily available according to a quick internet search.
|Thread: Can you ID this vintage lathe?|
It looks very reminiscent of a Drummond 5 inch, particularly the heavily T slotted cross-slide, see www.lathes.co.uk/drummond5inchphotoessay

|Thread: Identify linisher part|
Adrian - looking at the pictures in your link it says Reg'd Trademark cast above and below the name LINISHER. Using Linisher as a trademark in a search at the Intellectual Property Office comes up with 4 references. 3 of them are for Turner Machine Tools Limited, 63-68 Princip Street, Birmingham, 4, United Kingdom and are dated 1st Oct 1913, 30th April 1929 and the third which includes the word "OSCIMATIC" is dated 23rd May 1968.
One other reference comes up but the word changes to "Finisher", that is owned by Gühring KG, Herderstr. 50-54, Albstadt, 72458, Germany and is dated 11th March 2020 so very unlikely to be anything to do with your machine part.
Personally I'd look to see what I could find out about Turner Machine Tools. The status of all the Turner references is "dead" so I guess the company no longer exists although the IPO representative name is given as Barker Brettell LLP, 100 Hagley Road, Edgbaston, Birmingham, B16 8QQ, United Kingdom, who might have some information about the company as a last resort
Hope that's of some help.

|Thread: Drawing Projections|
I think you'll find that in land measurement the " A R P " refers to Acres, Roods (not rods) and Perches, the ration being 40 Perches = 1 Rood, 4 Roods = 1 Acre.
Where I used to live in the West Midlands (used to be part of Worcestershire) there was an location Rood End, I'm not sure whether it was named after the land measure or had ecclesiastical connections as in rood screen.
|Thread: Boat hull formula|
Bob if the tug that you are building is a scale model of a full size actual tug, look up the displacement of the full size vessel (internet search) and divide by the cube of the scale factor that you are building to, that will give you the weight that your model needs to be to float at the design waterline. If your model comes out lighter than that figure then you'll want ballast, if heavier then you might be better trying to loose some of the weight before you go too far. If the model is only slightly heavier than the "scale design" figure then don't worry too much, tugs can benefit from sitting a bit deeper to make sure that the propeller has enough water to "bite" on. Too much weight and then you're building a submarine!
|Thread: Reverse Sewing Machine Motor?|
It doesn't matter whether it's series or shunt wound, you still have to reverse the field in either the stator windings or the rotor relative to the other to get the reverse rotation. In the last month I've been through this exercise with a series wound dc motor (ex car fan blower) to enable reversing by just swapping the input leads. That required a full wave bridge between the rotor and stator windings to get the necessary field inversion in the stator. I believe that Taycol motors (amongst others) used a wound field and had a 2 pole reversing switch that did the necessary reconnection of either the rotor or stator winding as required.
