|Thread: Taper attachment capabilities ?|
That's really interesting Brian, thanks for taking the time to reply ( must have taken you ages to write all that ! )
One thing I have got is plenty of silver steel ( my father in law worked for Cromwell Tools and passed his staff discount onto me, so I used to buy loads of the stuff and keep it for a rainy day ) That will make a nice guide rod for a taper attachment. I think I've got some 20mm and I know I have a 20mm reamer.
I also scavenge broken printers ( last one cost me a euro ) for the guide rods that they use. The rods are quite accurate in dimension and sometimes come with a couple of nicely fitting sintered bronze bearings that the print head carriage slides on. They aren't thick enough for this job, but they are handy things to have around - they machine nicely too.
If there are 3 of them they can help me install it then - Baltazar looks pretty muscular
Great stuff Nobby, there are enough ideas there for a couple of years work
A simple cross slide used as a feed device for the cutting tool while the taper is put on by the taper set on the device is needed
My thoughts exactly John. I was wondering about the simple cross slide also incorporating a retracting tool holder.
Maybe Santa will bring me a brand new Hardinge HLV ? I've been good this year...
Hi Nobby, thanks for replying. I mentioned 45 degrees but that was really off the top off my head - 30 degrees would get me by - although it's not ideal.
I never realised how much I used a topslide until I didn't have one. I'm not even sure I'm barking up the correct tree here. It's not that I'm scared of making a topslide, I actually enjoy improving machine tools and making accessories - it's just that the centre height on the Emco is such that I don't have much space to play with in order to make one that isn't compromised in some way. Plus I have a requirement to cut morse tapers 1 through 3.
Ta Keith - I've fired off a PM to Nobby. Having viewed his album I now have to make one of those clever multi position carriage stops as well
|Thread: Free Machining Stainless Steel|
Nice work...if you know where there is any free machining titanium I'd love to buy some - all mine is of the opposite variety
|Thread: Taper attachment capabilities ?|
Thanks Keith, that's pretty helpful. I don't want to be a pain but could you link to the thread for me ? I can't seem to find it.
I'm thinking about making a taper turning attachment for my Compact 5 - how acute an angle can you achieve with these things ?
I know I'll have to build a topslide anyway, to put the cut on, but it could be a whole lot simpler if it didn't have to swivel as well.
|Thread: BV25 Lathe?|
I don't have a topslide either, although that's mainly because I haven't got one my tiny little Emco Compact 5 came without a topslide ( and half the tailstock missing and only one set of jaws for the chuck - good job it was cheap )
Tell you what, they might not be something that gets too much use, but it's a pain in the fundament when you need one and haven't got it.
A mate of mine bought a BV25 from Axminster quite a few years ago, they definitely did sell them.
For what it's worth he's had no trouble with it beyond the gearbox being a bit leaky.
|Thread: shot blasting|
The DEB product is Janitol Altrans - 30% phosphoric acid with a tiny bit of detergent
As acids go phosphoric is pretty benign and I don't think there are any safety issues beyond the usual common sense.
A 20% solution of phosphoric acid will clean and lightly etch steel parts very nicely without the hassle of blasting. If it proves difficult to buy the acid then DEB sell a tile cleaner which is basically diluted phosphoric acid and does the same job ( can't remember the name of it though, sorry )
I'm in Spain though David - it's difficult to buy anything secondhand here because they haven't really taken to the internet as quickly as other countries. As an example when we were looking to buy a car we found that there were only 3 pages of cars for sale on Ebay.es - three whole pages !
Quite often the line of least resistance is to buy from the UK, but something as bulky as a stool - it's only really practical when I have put together a number of items to be sent overland by an expat friend who runs a courier business.
A lot of the tourist bars on the coast are shutting down so we'll probably have a drive over there and get a barstool I can modify. Probably a steel one thinking about it, I've got welding tackle and prefer metalworking to woodworking.
Carpal Tunnel is no joke Neil, a really good mate of mine had it until recently and even though he's about the toughest guy I know it was driving him crazy. Fortunately the op fixed it.
David - thanks a lot for the pictures, I get the concept now. I think I can make something like that.
Farmer Dave - hello from another farmer ( we farm olives in Spain not a quick way to fame and fortune... ) I've got just such an office chair and it's really comfortable. With a modification to extend the height I'm sure it would be great, but my workshop is tiny and I wouldn't be able to use it in there. Good luck with your efforts to 'adapt and overcome'
Bazyle - Remap seems like a great organisation to be involved with, I wish I could help them but it wouldn't be practical with me being in Spain now
Thanks Bob, now I have seen a picture I realise we actually had one of those ( my wife used it to see if it helped with her back problems )
I found it comfortable to use but really difficult to get in and out of due to my knees being a bit secondhand.
Thanks for the kind words chaps. I've been a lot better since I emigrated to a dry warm climate ( although it's not so warm today ! )
It's very handy to know that a bar stool has it's limitations, I'd love to see a picture of a both a 'perch' and a 'straddling' stool - my woodworking skills don't extend much beyond gun stocks but I could probably make one, or maybe convert a bar stool.
I had a pretty apocalyptic bike crash 15 years ago and wasn't expected to walk again afterwards. I did walk again, but that and a fairly 'exciting' lifestyle have left me with all kinds of joint problems and aches and pains.
I have a few issues in the workshop, most of which could probably be solved by getting a bar stool so I can sit down when using the lathe and mill. The remainder would be solved if I just worked until I was a little tired, rather than carrying on until I suddenly realise I'm exhausted...
How do other people with physical problems cope ? what clever ideas do you have to keep you at your machines ?
|Thread: Cannon patterns, and Barrell castings|
I'm a little bit tempted by that Neil, but it would probably be more cost effective to get the original magazines. I don't really have any interest in steam engines, traction engines, locomotives or clocks so I don't think I'd get too much else out of the subscription.
I'll check the index though, if there are enough articles on miniature machine tools and models of full size IC engines ( which I am very interested in ) it could be a goer.
Yeah, that's a standard practice, and a very good one too. If someone was thinking of making a full size model firearm then that would definitely be the way to go ( although there is a legal can of worms involved with that called the VCR bill - I won't go into it as it wouldn't apply to cannon and I actually don't know too much about the letter of that particular law as all the people I dealt with were exempt under one category or another )
I think ME has published an article about building a Colt Peacemaker and at least one 20th century artillery piece. I'd love copies of those issues. What I would really like the most are the blueprints for the M1 155mm 'Long Tom' gun which my late Dad served on during his time in the Royal Artillery, but that's probably a longer shot than even the Long Tom could manage
It's not how it looks to a layman Clive, it's how it looks to the Forensic Science Service - I've gotten a pretty good handle on how they think over the years as I'd sometimes build inert or blank firing weapons for the military re-enactment guys ( my No1 priority being not to go to jail, making money was the secondary priority )
As an example I have seen ( approved ) ACW percussion muskets with a 90% completed bore and no hardened insert to prevent the last 10% being finished. The FSS view was obviously that the tools and skills needed to do so were beyond the hypothetical ' average man in an average garden shed '
Nothing wrong with your scheme at all, technically it's better than mine - but it's not strictly neccessary. What you propose is like a halfway house between my method and the full on deactivation procedure required for live firearms.
I wouldn't make peering into the muzzle of cannons a habit by the way, but if you built it and you know that it's inert then I think that's fair enough. Excellent poem though
The full name of the author is Ian V Hogg - expert on all kinds of firearms - and I had his book on artillery. Sadly I had to sell 90% of my books before I emigrated and that was one of them.
