... discovered an interesting patent.

Vinton's Lathe Chuck is worth a look.

 

I see that the "other"(?) Tubal Cain posted a video last month about something very similar.

.

Thanks for the video link, Murray

Yes; the Horton chuck is broadly similar, and the video is helpful; although I do worry about some of his interpretation. [e.g. he seems to think that the bevel gears were press fitted onto the screws]

The big difference, however, is Vinton's inclusion of face ratchets [if that's the correct term] on each of the screw assemblies, to allow micro-adjustment ... This is the feature that I [wrongly] thought might capture the collective imagination of the forum.

Edit: ... or did I misunderstand Vinton's drawing question

P.S.  This is the page that started me investigating Vinton.

Not exactly 'What did you do today' but in the same vein, 'What I have finished lately' 13 amp oscillating engine, from plans provided by...

**LINK**

13 amp pin engine.jpg

Only small but requires approx 45 psi to operate it... qualified by designer.

The link also provides access to plans for those looking for something different.

I'm feeling a bit chuffed. Just had a go at my first thread-cutting having finally modded stuff so i could get the right changewheels in. I chose an M16 cos it's the largest commercial nut I have lying around and my practice steel bar is 1.24 inches and I've been turning a section down for practice anyway. The nut fits as well as it does on the commercial bolt!!

i spent yesterday evening restoring a now rare example of one of the late Ted Linden's injector , making a new steam cone to replace the damaged original. rather nice to think that one of Ted's injectors will continue in use 60/70 years since first made on a miniature steam loco. they were excellent injectors. (more pics in recent album).

cheers,

julian

Thought I'd start a new post for the new year as Neil and Jason have over indulged on the home made raspberry wine cheeky will will post later.

G'day John

Lovely thread but judging by last years contributions have you considered 'What Did You Do This Month'?

Now as for home made wine, as a Christmas 'treat' I was offered some 'grappa' from a mate of European ancestry.

All I remember was waking up the next day and observing that the potion might be useful as a universal paint stripper/degreaser.

In the workshop I manufactured a concentricity gauge and a bubble level to remove a few more excuses as to why I can't hit the bull with an Anschutz . Then made some wind flags, they worked! (photo's available if anybody is interested) but probably not model engineering although the concentricity gauge may be useful for checking crankshafts.

Spent the day mounting locks on and painting a solid wood external door for the garage, to replace the shonky thin veneer internal door that some little baskets kicked in while we were away for Christmas. Luckily they could not get into the back shed where all the tools etc are. Only a couple of old Harleys and handful of other bikes in the house garage that they were not interested in. They woulndt have got the bikes out anyway, had the roller doors dyna-bolted to the concrete slab etc. Even had the outside access hinged wooden door barred with a 2 x4 on the inside -- but they just kicked a hole through the sub-standard door and crawled in.

Also jimmied the bedroom patio door and security screen and turned the house upside down, making off with some bits of heirloom jewellery but not much else (don't have much else of value outside the shed and garage!)

So have also been busy installing motion detector lights, alarm system and beefing up door locks all round. Turns out those sliding aluminium framed glass doors and matching diamond mesh "security" doors are easier to pop open than a paint tin. They all rely on locks held to the soft ally frame with tiny PK screws. Not any more. All anchored into the concrete block walls with dyna-bolts now. And all sliding doors and windows now have a 5/16" stainless pin that can be inserted into a hole drilled through the track frame and the door/window so they are actually immovable (which i had foolishly believed was the function of a lock. Silly me).

It certainly has been a good wake up call.

When we moved in here we had an old sliding patio door replaced with French Windows. When the window fitters removed the old door I was horrified how easily and quickly it came out, literally just seconds with just a jemmy. Frightening.

Low life scum also nicked a pair of 47kg propane bottles from outside our house a year ago, the security cable was just chopped with bolt croppers. Same happened to a lady up the road at the same time, so obviously someone was short on heating and needed a load of replacements without paying for it. First thing plod asked was did we have CCTV. We have now, covers front and back, but if scum comes all hooded up not sure how good it will be but we can keep tabs on the house now while we are away via the Internet.

For all you people who worry about security- I was at a funeral, the coffin had to come out thru' the window. Double glazed, plastic frame. I was amazed how quick the glass came out, and replaced without a mark. May be more modern ones are a bit safer.

Olly.

Ok. The bubble is still work in progress, this is where I'm up to, the glass was pinched from an ancient turntable levelling device btw.

The wind flags were made after I realised how even a slight breeze can affect a projectile. Notice how some ****hole took a poke at one of them. The culprit was identified and is on warning for a 6 month suspension if it happens again.

The concentricity gauge was a labour of love, it took me a whole year of 'should I or shouldn't I finish the project' - but it was worth it, only to prove that modern .22 ammo from reputable manufacturers is very good and .

As for the commercial offerings, you be the judge.

At the end of the day I got this deja-vue thought.

Nice work Danny !

I use a Neco Gauge for my cases and had pondered its uses for model IC engines to check crankshafts and camshafts.

Are you going to make an internal anvil so you can check case wall concentricity ?

They should have punted the twit that shot at your flag - it is really bad form to do this to someone on purpose .

I suppose the fly boys could use a flag similar to this as you can change the height of the pole to get wind readings at different heights.

I have a few books that i found helpful for shooting, applied ballistics by Brian Litz and competition reloading by Glen Zediker that were excellent reading.

To get back on topic i continued to work on my lathe bench mods and it is now 150mm lower and has screw down levelling feet ( mostly used to take any wobble out as the floor of my shed is far from flat ) so now painted and ready for ply carcass but now undecided if i want to paint the ply the same as the frame (deep ocean blue but looks more grey to me) or put a clear finish on the ply.

I enclosed my steel bench and fitted a new form ply top and the bare ply sides doIan brighten things up a little but if i do this to the lathe i will have to do the same for my X2 mill and C2 lathe !

Oh the heartache of decision !

I would never make it as an interior designer - i paint every thing the same colour ,usually what ever i have the most of so when i purchased 4lt of navy blue killrust for my trailer guess what colour most of my workshop ended up being!

It's amazing what they can do with forensic ballistics...

Seriously, a couple of nice projects. The concentricity gauge could make an interesting article.

Very nice work Danny will be copying the wind flags youre concentricty gauge is in a different league to my RCBS one.

Ian.

To check internal run out I just put the DTI probe inside the neck. The carriers have a magnet in the base btw.

I never thought of using the device to measure cam-lift but that's a great idea. Would need a degree wheel though.

At the end of the day, something worked as I got this from the club.

Machined the crankcase for the Nemett Lynx I'm doing at the moment. Decided to make the engine mounting bearers integral with the case.
