Thank you for that, I will investigate this, could be a simple mod then.

Andrew, thank you, very helpful.

Naturally I meant 6082 aluminium, but then I also meant this question to be posted in tools and tooling. Best not mess with the actual cutter itself until I remember where I am and what I am supposed to be doing!

graham.

Sorry, I meant to post this in Tools and Tooling, my apologies.

Could anyone with experience of these roughing out cutters give me their opinion, their experience - of them?

I have a couple in 12mm and before I try to maim myself, or worse, destroy good work, could someone give me an idea of feed/speed for say 8082 aluminium?

Thanks,

graham.

Looking at the Dan Gelbart videos highlighted in the Rotary Laser Centre finder thread I was inspired to build a magnifying video display. So far I have bought a reversing camera for a car complete with 7" LCD monitor.

That is as far as I have got though as I need to obtain a magnifying lens for the camera, which requires me doing a bit of research so I need to allocate some time to it. I am quite hopeful that it will help out when I am turning some of the smaller components I work on.

Drove me potty not seeing the image.

Where are they then?

I do not know Mark from Adam. (just wanted to clarify this) But I think people need to remember what his post said and he was quite emphatic that he was offering his services for Model Engineers and not for commercial enterprise. There is a distinction. I realise it may be a subtle one but not insignificant, especially cost wise.

Also, it appears to me that the chap had over a hundred posts on this forum so not a one off spammer. I remember quite clearly one person posting on here seven or more times and each and every one of those posts was to promote a machinery moving service? Why was that not censored?

I realise that there must be a bit of censure regarding commercial posts and people pay to advertise on here. But I believe the chap was genuinely trying to offer a "micro service".

That's my view on it for what it's worth and because I believe that I can see both sides quite clearly I am sticking with my views.

I see absolutely NOTHING wrong with doing paid work.

By doing this (paid work) I have fed my family for many, many years.

I saw your advert and it was pretty explicit, it was for the hobbyist. This should be encouraged. I have no idea - nor do I particularly wish to know - who censured your post. But I would love to see the rule that says you should not have done this. Retrospective rule making is just not the way forward.

On a personal note I have started casting again. I say 'again' but the reality is that as a schoolboy I did a good deal of casting in White Metal and a good few years have now passed. A while ago when I wanted to make something in Aluminium I thought I might just "Do it Myself" and it has gone on from there. I am presently setting up to cast in Bronze. And thoroughly enjoying it too.

graham.

The same way I do right now Jason, pay someone.

I really do not mean to be contentious about this, and this is not directed at anyone. But to become really competent at CAD, any version, is not an overnight 3D CAD (or 2D CAD) for Dummies read. It takes a long time to become very competent AND quick. Also, as has been pointed out, good software is not cheap.

I am very interested in the technology and I think that the possibilities are very, very exciting. I would much rather just give one of my (now infamous) pencil sketches to someone and let them come up with the drawing, usually before I can get the compfuser turned on.

As an exercise I think a 3D printer would be 'fun' but to get the accuracy I need for anything a £500 box of bits assemble it yourself RepRap machine will not cut it. I don't need another hobby right now and I have a finite amount of time for the ones I do have.

graham.

IanT has summed it up. After spending many thousands of pound on (now defunct) computer hardware, especially in the very beginnings of the PC my attitude is quite simply, Give me a call when it all works.

I will not be spending any money on a 3D printer anytime soon and IF i need anything 3D printed I will just continue to send a drawing + money to one of the reputable printshops.

At this stage of the game, I have absolutely zero interest in learning 3D CAD. I have far too many other things going on. So, having said all of that, I am always interested in reading about the latest developments.

graham.

As always, the thread has been an education.

I now know what a Rose Engine is though I have long since seen the Holzapfel lathes, fascinating.

I am really ruthless when it comes to "corners", my workshop is one of those 'organised' ones. I can't be doing with disorganised catastrophe. My memory isn't good enough, I need everything to have a place so I can remember where I put it, whatever IT is

My first thoughts were a Tool and Cutter grinder, more specifically, something to sharpen drill bits with. I have all the components, including the material for the table and bracketry/adaptors so it would cost me nothing other than time so the consensus seems to be that route.

old Al is right though, I have a sort of rule of thumb: If I haven't used it in the last six months it is time to move it on. Tailstock and a few of the other bits are Bin Bound though, the Controller board I will sell and put the money to good use, IF it sells. The covers and boxing are also bin bound.

Michael, the headstock casting is 15.5 x 9 x 14 cm approx increasing to 22cm long if you take into account the shaft and gearing.

graham.

So what is a rose engine? Excuse my ignorance.

graham.

I don't think so Michael. The headstock casting is no lightweight and add a motor..........

I'll give that one a miss I think.

So, I am now the proud owner of this pile of bits. Once upon a time it was a Seig C3 lathe, it's now a collection of parts.

I had originally thought to make a tool and cutter grinder - I have a nice quarter horse motor with a VFD - and mill the top side flush and the bottom carriage flush which would give me an X/Y table and attach a collet chuck to the top slide for the cutters.

Then I thought I might buy one of the X2 column and bases from Ketan and make a small Mill. Then I thought of taking the little DRO's off the topslide and trying to adapt them for my Chester Lathe.

THEN I thought it might be a good idea to do NONE of the above and save myself a load of time and aggravation. But that's no fun now is it?

Well I would be the first to admit I don't know much about Loco's. But I do know a bit about paint.

I have, for many years, bought paint from Brown Brothers. The place to contact is Brown Brothers Darlington and even though I now live miles away I still enjoy good service from their supply department.

For all of my "brush on" projects I use their "Tractol" range of Coach Paint. This may be available from other suppliers but I am unlikely to change. They have supplied Coach Paints to most everyone in the Teesside area over the years and this included "Central Works" when the Coach company still operated it, before it was shamelessly dismantled.

Anyway, back to the plot. I have never achieved the depth of finish with any other type of paint. If you want a quick brush it on -forget it, type finish this may not be for you. But if you want a genuine authentic finish, this is the real thing.They can also match any colour. However, the down side is minimum of half a litre. Which isn't too bad compared to some of the prices I see some people charging for half that quantity of paint.

THIS is what you are looking for I think.

Ian, it's a Radial Drill, the head slides forwards and backwards on dovetails.
I don't think that's a Hopper either, more like a guard for the conical drive pulley, the motor is directly on the other side.
The table slides up and down the column, the head is fixed.

And as I said, very nice.

Well I got one of them right anyway!

Thanks for that. I will put that "right" in the morning and more likely get the next job ready for the scrap bin
