Thread: New-style cover finish
19/05/2022 18:06:33

Hi Tim.

The problem was noted quite some time ago when Model Boat magazine adopted the over glossy cover, quite a few subscribers were less than impressed. Stacking them has to be done carefully.

As a subscriber to both MEW and Model Boats i was hoping that the new owners would make the cover finishes the same by going for the less glossy/slippery version that MEW used. It looks like they've jumped the other way unfortunately.

Thread: 400mm V band clamp, how to make?

Ian - have a look at **LINK**  (Neophix.co.uk). They reckon they do up to 2000 (2m) dia, and a wide choice of fastening methods.

No connection - just found them with a search using Google.

For another pillar tool made without castings have a look at the following document:-

**LINK** ( https://www.haythornthwaite.com/149 Pillar Tool.pdf )

That was made larger than the GHT design but the same type of construction could be used at pretty much any sensible scale, you just need to work around pipe fitting sizes.

Thread: hi from Belfast ...

I wouldn't be in too much of a rush to get rid of the indexing unit, especially just for the cost of postage. Even though you say most of your work will be on motorbikes it would be handy to have that unit when you need to cut the hexagon heads on those "very special" bolts that the main dealer wants an arm and a leg for, or for that special adaptor that needs bolt holes spacing on a pcd - and there are 13 holes or similar. It won't cost anything to keep on a shelf for the time being until you are absolutely convinced that you'll never need it.

At the moment if you're new to lathes don't throw anything out or give it away until you've found out what it is and what it can be used for. As you get more experience you'll find uses for all sorts of stuff that you won't even recognise at the moment.

My money would be on a double swivel vertical slide with an indexing attachment fitted to it. The item that SOD has labelled "support" is the detent plunger that engages with the space between teeth on the indexing gear that is fitted to the end of the main shaft, (labelled as missing pulley by SOD ). The holder for the detent plunger can be slid along the slot to accommodate various diameters, and hence tooth count, of the indexing gear wheel. My guess would be that the two "roller" type parts could be to carry/guide a weighted cord that is used to ensure that the indexing gear is kept against the appropriate face of the indexing detent plunger.

Does the lathe have mechanically changeable speed ranges (belts or gears)? If so those red sectors look as if they could be the bottom end speed that the motor can be run at. So if the speed you want, in the mechanical range that you have set, puts the pointer in the red then select a lower mechanical range and run the motor quicker. Motors don't like being flogged at low speed as the cooling fans aren't working efficiently and the windings can cook. The yellow sector probably shows where the motor is being run at significantly higher frequency than the nominal 50/60Hz and so the torque available will be falling off or the losses could be getting higher leading to overheating

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?
24/12/2021 18:27:12

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
14/11/2021 15:31:57

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
14/11/2021 14:02:05

Hello Ray

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)

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
01/07/2021 18:38:29

Yep, Drummond M type.

For a LOT of info try the "drummondlathe@groups.io".

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.

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.

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.

What about ordinary kitchen cling-film?

Thread: Covid 19 and the DVLA
24/03/2021 00:39:04

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: Any idea on what this item is?
07/02/2021 11:21:10

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.
