|Thread: Making a ring mandrel- jewellery tooling|
Not a bottle opener, just a large choil from knife making terminology.
Would work as a bottle opener though with robust enough metal.
All the tash combs I have seen are wood or plastic, I wanted something with a bit more oomph lol.
Unusual jewellery style project here, pair of moustache combs in nickel silver with pearl handle and gold rivets.
File work on the spine of the larger comb.
As an engineering solution I would definitely turn a ring from titanium.
I've made quite a few over the years, both male and female styles.
Heating the titanium when finished gives a beautiful colour finish, but I also file work them for decoration.
It's far easier to make the ring to size on a lathe for me, unless you're going to precious metals and have very deep.pockets.
|Thread: A Question on Bench Blocks|
I have an original Starett bench block in unused condition. Both holes in the vee are exactly central, no offset at all.
I would guess the drawing is wrong as I cant see any reason for having a hole offset as shown.
I will post an image if necessary
|Thread: Outdoor notice board|
I'm running a community project to refresh a neglected area of land close to where I live.
We have been advised to put up a notice board or interpretation board to show people who we are and what we are doing.
We have been looking at commercially available ones and for anything decently strong we are looking at over 2 grand!
I'm sure the fabrication is fairly straight forward, I'm thinking that rather than hinge the door I will make it a bolt over cover for security and resilience.
Does anyone have any ideas or suggestions of what i can do to create something fairly tough and idiot resistant.
|Thread: Scale Field Gun or Howitzer plans|
Have you looked at Armortek 1/6 scale kits?
They do a couple of field guns and the ammunition limber.
Very nicely machined but lots of scope for extra detailing and work. I built their Centurion tank and spent many hours machining extra parts and details to make it so much more accurate.
If you are not sold on making your own plans and dont mind building from a metal kit you can spend a lot if time on really super detailing it.
Once materials and machining are counted in the cost of these kits is not bad.

|Thread: Brake band friction lining|
Just to update, the guys at Custom brakes in Sheffield were fantastic. I dropped off the brake band at 10 am and they rang to say I could collect it at 3pm.
Made a fabulous job, grit blasting the friction surfaces, heat bonding a new lining in place and getting the unit ready to refit.
They said if it has friction surfaces we can refurbish it. No matter how big or small.
No connection to them but heartily recommend them of you need friction linings sorting out.
Custom brakes in Sheffield are the most convenient and were very helpful on the phone. Just drop it off and it will be back with you next working day, guaranteed oven bonded so for 30 quid that's the best bet.
Many thanks for all suggestions.
Thanks chaps. Trimat were my first port of call but they only do large quantities for industrial purposes. They put me in to Jim Jack.
I just wondered if anyone had a supplier they had used.
I'm currently renovating a Wheelhorse garden tractor a d the brake band is pretty shot.
It is a thin steel backing strip with some kind of friction material bonded to it.
Does anyone know what type of flexible friction material I need and where to get it from.
I have emailed a brake lining company called jim jack services in cumbernauld a d await their response.
|Thread: Small Metric Screws|
PTS-UK are very good for small screws.
There is one on ebay at present. Go for it if it is your dream tool.
|Thread: Home built trailer|
Update from the government re my enquiry. Case closed lol.
Good afternoon Mick.
Many thanks for your recent e-mail which has been passed to the Approvals Technical department in order to reply to your concerns. Firstly, please accept our apologies for the delay in replying, the department is extremely busy at this time.
Any “new” trailer, be it manufactured by a company or self-built, will be required to have an approval before it is first used on a public road. Small trailers however are not as such “registered”.
For trailers manufactured in small numbers or for self-builds, these would usually be approved through Individual Vehicle Approval (IVA). The IVA scheme is administered by ourselves (the DVSA).
Please follow the link below for more information on the IVA Scheme;
The technical requirements that a trailer must meet can be found in the IVA Inspection Manual for Trailers;
For your trailer with a GVW not exceeding 750kg, this would be classed as a Category O1 Trailer.
Once you have completed the build, you must apply for an inspection using the correct application form (IVA1T);
This must be submitted electronically on our Technical Application Submission (TAS) system;
You can find a list of IVA test sites and the Category of vehicles they can accommodate in the interactive map in the link below (best viewed in Chrome or Firefox);
The fee for an IVA inspection on a Category O1 trailer is £70.00.
Once your trailer meets with the requirements, you will be issued with an Individual Approval Certificate (IAC). This will then permit you to use your trailer on a public road.
I hope that you find this information helpful and apologise again for the delay in replying.
Many thanks & best regards,
Steve Bardsley | DVSA Vehicle Approvals Technical Team
|Thread: Seeking advice on suitable lathe|
I have made several finger rings from titanium using a lathe, the final sizing cuts are done using boring bars rather than drills.
There is a lot of waste but you can collect the swarf to scrap easily if you're only using the one metal.
A Raglan Loughborough would be my choice if I was only making rings on it.
|Thread: Equity release!|
You need to find a good, independent financial adviser. Someone who can look at the options and give you the best advice.
I will be looking to do the same thing in due course, with the exception of soending it on women as the current head of domestic affairs may have something to say about that!
But having no kids and no mortgage means I can enjoy some of the cash I've pumped into this pile of bricks I live in.
Maybe a nicer car, or a few toys.

|Thread: Help milling an angle|
I dont understand the question. Are you making a flat plate identical to the drawing with a 60 degree angle?
Or are you making a flat plate with angled long edges? Your post is not clear hence the confusion.
If it's the former, rough it out with a saw and finish with files or a belt grinder. There is no need to waste time on a milling machine when it could be done much more quickly as I suggest.
|Thread: Just for fun what’s this stuck in my tyre?|
Well it was a weird item to find lodged in a tyre for sure.
Strangest I saw was a 13mm combination spanner right through the crown plies. I would have said it was impossible but there is was! No malicious action just a stunning example of sods law that if it can go wrong it will go wrong.
I recall Stelrad at Swinton sending a skip full of metal shards from their stamping press off to the scrap man. Damaged skip left a lethal trail of these tiny, sharp off cuts along the main road. Literally dozens of cars with all four boots holed. And my entire shift on hands and knees with magnets recovering them. Tyre dealers were ecstatic, Stelrad not so lol....
|Thread: Home Workshop Site|
Please pass on my very best wishes for a speedy recovery and good health to return
|Thread: Wasp trap - suggestions please|
Google waspinator. It's a really effective wasp deterrent rather than trap.
The highly territorial wasps see what looks like an established nest and go elsewhere.
It really works and is eco friendly.
