Thread: Car boot gizmo identification?
19/06/2022 09:05:32

Glassblowers torch? Possibly specific to laboratory glass blowing and the manufacture of special apparatus.

Thread: Yet another unidentified tool
05/06/2022 18:00:32

A veneer or banding trimmer?

Thread: Imperial Brass Strip
21/04/2022 14:20:39

K & S Metals - from modelmakers hobby shops do 1/4" by 1/32" by 12" long which could be cut down. Otherwise you will need to buy suitable sheet and cut a strip from it.

Thread: Polishing Brass
05/04/2022 21:50:19

Not a belt sander! It's the last thing you should use. File the edges of the brass using fine files (No4 or No6 cut).  Then polish use diminishing grades of emery paper - start at 400 or 600 grit and follow with 600, 800 then 1200. After that you can use a micro polishing paper ( i think its called 3000 grade?) (or best of all crocus paper if you can still get it). Lastly use Solvol Autosol polish (its a paste that comes in a tube).

Lots of patience and you will get a mirror polish. Remember to never go to a finer grade of paper until you have removed all the scratches from the previous one.

Thread: Newton Tesla Motor units
17/03/2022 10:07:00

I just bought a hand held tachometer and use that if I need to know the exact speed. I did use it to construct a graph of actual speed vs frequency setting - one line for each belt position.

I do have a tachometer fixed to the milling machine and that is useful, however you soon get used to setting the correct speed by "feel".

Thread: What is it?
20/02/2022 14:16:57

Clockmakers depthing tool - for setting out the pivots of wheels and pinions.

Thread: If epoxy adhesives fail to set within 24 hours, is there any hope that they will EVER do so?
14/02/2022 16:58:53

If it is both Brittle and sticky then the most likely cause is that it was not fully mixed. Otherwise I agree with the above - warm it by placing above a radiator for a day.

Thread: Workshop Practice #49 worth it?
05/02/2022 16:41:02

it describes the Milling machine and has photos and brief descriptions of several commercially available machines as examples. It also describes the additional equipment that you may need (e.g. rotary tables, dividing heads, clamps and vices). There is a section on basic use of the machine and a short chapter on keeping your cutters in good condition.

My copy was published in 2011 and, unless there has been an update, it is really quite out of date from the point of view of machinery that is currently available.

Thread: Smart TV
25/01/2022 10:28:24

You will need a SCART to HDMI converter. Cost about £10 -£30 depending on which shop you use.

Thread: Unusual Leather Rolling Machine
17/01/2022 17:20:03

Googling Shoemakers leather rolling machine threw up quite a few hits.

Thread: 80mm ARC Versatile or 73mm Precision 3?
27/11/2021 10:15:26

Just to add - they are excellent vices and the price is pretty much unbeatable for the quality. (usual disclaimer).  For the hobbymat table the 2" may be the better choice.

The MSC ones have a deep groove down both sides for clamping. The catalogue picture is incorrect in showing just a row of holes (At least on the ones I bought about a month ago with the same code number)

Thread: Replacement surgical blades for Swann Morton scalpel handles
03/11/2021 14:56:42

Any model shop should have them or try any online model shop. Wonderland models has packs of 10 blades for 99p (usual disclaimer). do check though as some shops charge considerably more!!

Thread: Cycle speedometer
03/11/2021 09:48:18

I seem to recall that Keith Wilson wrote up using a cycle speedometer for a loco in ME some years ago (Maybe sometime in the 80's or 90's??). He gave all the details and how to calibrate the thing.

Thread: A Tower Clock project
30/10/2021 16:28:11

If you can get hold of a copy of John Wildings "Small Tower clock movement" it gives a full description of the construction of a clock similar to your own ideas. It is £30 from here: Clock Book - Well worth the money (It's on my own list of "projects to do"!)

Thread: Cutting Brass Sheet
19/10/2021 14:11:17

I doubt if you could straighten your sheets without leaving some marks. If you are lucky you may be able to use the undamaged areas between the folds? Have you tried UK suppliers? Both M-Machine and Mallard Metals (to name just two and with the usual disclaimer) list 0.5mm (actually 26swg) sheet in their catalogues at about £8 for a square foot. They are likely to pack it properly and you should receive it flat.

Thread: Another what is it?
04/10/2021 12:06:31

Correx Gauge - they still make 'em!!: Here

Thread: Grinding tool bits
01/10/2021 10:34:26

You can buy blanks that are much shorter than 20cm! Then you will not need to cut them. Try this video about tool grinding - It is excellent and takes you through the process slowly with a full explanation of "how and why". Here

Thread: DRO scale Modification
19/09/2021 10:01:24

Have a look on Youtube - there are several videos. Have a look at a few of them and you should find a method that suits you and your available tools.

Thread: Type 2 precision vice from Arc euro
06/09/2021 12:50:59

I believe it is so you can hold the vice in another vice and still be able to operate the moving jaw. Sometimes a very useful trick! Or, as you suggest, still be able to use the vice on its side or pushed up against something like an angle plate or 123 block.
