Thread: CNC dedicated mill or CNC converted mill?
14/07/2020 09:32:45

Is it a possibility to 'rough out' with a hobby CNC mill and then finish the crucial dimensions with say a surface grinder or in a manual way? Based on what others are saying it sounds like producing parts to that spec purely with a CNC mill might be beyond your budget

Sorry yes, he founded Airspeeds in the interwar years. Seems like an odd place to have an aircraft factory, in those days in York the only way to get out by vehicle was through the bar walls or under low rail bridges so access must have been a problem.

He owned an aircraft factory in central York before world war 1. It was demolished a couple of years ago.

Adam Booth talks about the forces generated when taking 1/2 inch cuts in steel on his Monarch - has anyone got an idea of what they would be and how they would compare to the toolpost mounted Skyhook?

A word of caution, I had an excellent Canon G7X and we got caught in severe weather in the Lake Distrct last year, water got in and it was wrecked.

Thread: Telescopic bore gauges.

Once you get the technique right with practice they are pretty accurate. I have the gauge at an angle in the bore, nip up the screw, move the gauge perpendicular which pushes it closed until I can feel no more resistance and then remove the gauge for measuring with a mike.

That P&W manual is really nicely written. Very different to modern manuals.

I am in 2 minds on the value of HS2. On one hand the cost and short term environmental impact is huge. On the other hand I spent 4 weeks last year on long distance train holiday in Europe - Paris to Strasbourg in luxury, silence and comfort in a couple of hous, most of way we sat at just over 200 mph. Similar journies across Germany, Austria and from Venice to Milan although not as fast as TGV. These were not expensive tickets compared to what we are used to in this country. That showed me that the end result of these projects. To be fair the journey down from York to London on the east coast mainline was also good but wasn't cheap.

On this forum we often complain about the lack of engineering now in this country but this sort of massive project is just the sort of thing that can disprove that. John's initial post and photo shows what sites will look like during construction but I think the plan is to replant all this after its built so it is a temporary eyesore. Looking at old photos of railway line construction in Victorian times it looks like hell on earth and thousands of people died building them.

I do think there is a case to reverse some of the Beeching cuts though, and have more local lines and stations and improve the lines we already have. Maybe that would benefit more people, take cars off the road and give much better value for money.

Thread: Centroid Acorn experience

Martin - I got your settings file up and running and it helped me make a decision, thanks. I ordered a PlanetCNC setup yesterday for my Denford Orac conversion so it should be here next week hopefully. A 4 axis USB board, a board to control a VFD and a license. My plan is to get it running on a raspberry pi with a touchscreen and try to recreate the original Orac design that had a small VDU built into the base of the lathe.

BTW - if anyone is interested in Centroid Acorn I found a way to potentially get a discount, PM me for the details.

For this conversion the cheapest bit has been the lathe itself!

I ordered a PlanetCNC setup yesterday for my Denford Orac conversion. A 4 axis board, a board to control a VFD and a software license. My plan is to get it running on a raspberry pi with a touchscreen and try to recreate the original Orac design that had a small VDU built into the base of the lathe.

I seriously considered Centroid Acorn and it looks solid, it needs a high spec Windows 10 PC though and ideally a high res touch screen which really racks up the cost.

Thread: Manual control of CNC
20/04/2020 11:22:21

I do quite a bit of basic machining on my Seig KX3 by just manually typing in lines of G code. Manually jogging during setup with all maching done by g code - either manually entered for simple stuff or from CamBam. I don't miss having a manual way to control the machine beyond this.

Hi - I have tried fixing walking boot soles a few times and it has never really worked for more than a couple of uses and you risk being stuck somewhere remote if they come off half way round a walk. I also tried getting them fixed professionally by a cobbler and that failed too. The soles take such a battering in this country and walking conditions can be so wet and acidic that even top quality boots seem to last for 3 or 4 years for me.

MASSO have a UK supplier - the lathe version is £640 which is 1 to 1 with the $, so again much more expensive in this country.

Blowlamp - i will use your files and have a play.

16/04/2020 11:38:02

Masso looks great - not having to bother with a PC is a big advantage. It isn't cheap though at $630 US with VAT, import duty and delivery on top - probaly around the £700 mark. We seem to be in a blackhole in the UK having to pay a big wack of import duties and tax on everything.

16/04/2020 09:15:27

I contacted PlanetCNC and got a quick reply, a motion control board, a board to control spindle speed and a software license comes in at about £250. So much cheaper than Centroid Acorn. PlanetCNC software can also run on Linux, Mac or a Raspberry PI whilst Acorn needs a fast PC with Windows 10 - so a potential big cost saving there. I presume a power supply is needed for the board too. Documentation seems somewhat sparse so I assume support is via a forum but that is also the case for Centroid Acorn.

I downloaded the software and gave it a quick trial, it seems very simple and obvious to use. It seems set up for mill or router use with 4 axes displayed and a 3D view of the part. I could not see any way to customise or get a lathe centric view - it must be possible though as you have that in your video Blowlamp, was that a simple job to customise?

That looks great Jason - lovely job. Did you have any issue with the milling cutter going blunt part way through? Andy
