Acetone cleans it off quite quickly although might affect the base material - always do your test patch!

I must mention George at Emvio Engineering who is the UK importer for Syil, George has been an absolute treasure throughout the process, from enquiry right through to commissioning, his support and assistance is brilliant and has really helped to smooth the process right up to the first cuts under CNC control.

This video gives a hint of what the Syil X7 is capable, here it's cutting a 3mm deep pocket in 316, entry was spiral then full 3mm DOC using a 10mm 4 flute carbide roughing endmill with 33% step over at 1170rpm and 126 mm/min with very reasonable noise levels, the mill noise was not noticeable above the background noise outside my workshop.

I'm not sure I would want that technology in the garage.

If you're the kinda guy to stick you hand in the working area you're definitely best off without.

Consider that a Pressure Washer presents most of the same dangers to the hard of thinking without any of the safeties!

Although I did look at Tormach and Skyfire at the start of this journey I don't think the X7 is intended as competition for either, the X7 is far more rigid and massive and has a base casting, not a stand.

It is my personal machine and will be used for motorcycle parts for me but I will be doing some commercial work with it, the commercial stuff is covered by NDAs so I'm not at liberty to give details without the permission of the IP owners until the products are released into the UK market.

It's the Syil X7 with 12 tool changer, the big 4th (that's the hand wheel on the tailstock!) , Siemens 808d Advanced controller and Siemens servos and drives, the factory were very kind in including the laser ballscrew mapping at no extra charge.
The massive column and base castings were a significant part of the appeal of the X7, the absence of proprietary gubbins you can't buy elsewhere was also a consideration.
I've had my nose to the grindstone replacing the shower enclosure at the behest of SWMBO this weekend and this morning, back to work on the garage today! :D

That's it in position, just the complete rewire of the workshop to do, the cable trays are going in next week :D

Thread: Metal ball joints for 1/3 scale action figure?
10/03/2019 09:21:34

It's worth looking at how the original Action Man figures joints were articulated, with a combination of hinges and swivels they give realistic articulation with lass complexity than ball joints.

Thread: Sizing an M2 thread during screwcutting
27/02/2019 08:33:57

I'd go with a set of M2 chasers for one of my die heads.

Thread: Carbide inserts again.

If you cut away from the shoulder there are no worries about speed.

Thread: Myford cross slide backlash
20/02/2019 09:43:50

You can use thrust bearings to eliminate any backlash from the adjusting collar system, you do need to machine the cross slide end plate casting to accommodate the bearings though.

Thread: 3 Jaw self centering ER chuck
19/02/2019 23:02:12

It's a significant geometrical compromise and not a very clever way to use a dual taper collet.

You can probably hold hex too but it won't fit in the slits so may not be so accurate.

It actually works perfectly well with square, hex and octagonal

Grease is a suspension of oil in a soap, over many years the lighter fractions in the oil will evaporate and the soap can also degrade and set, a Lithium Soap based grease is more stable and lasts longer and in a Synthetic Grease the oil component is "Built" from molecules rather than refined and so doesn't have lighter fractions to evaporate.

Thread: Aluminium black
10/02/2019 23:39:15

Chemicals like Birchwood Casey Aluminium Black work fine on material that's been exposed to air for weeks as long as it's well cleaned and degreased, keeping the surface to be treated covered with adequate fresh solution is essential, wiping it on and leaving it is a recipe for patchy results, different alloys take colour differently.

Thread: new toy tormach 1100

I think the guy on the video is hoping a lot to hold .001" on a diameter

He was trying to do what Tormach told him the mill could do prior to it's purchase, it's irrelevant WHAT he was trying to do, the point is they refunded him because they lied about the capabilities of their machines.

Thread: Noise from lathe drive

Double your motor power and go 4 pole, the increased power will deliver adequate torque at lower speeds than the less powerful motor can manage.
If you choose a good quality 4-pole you can safely run at up to 200% of rated 60hz speed as the rotor construction is close enough to the 2 pole version as makes no difference.
You'll likely cover all the speeds you need without ratio changes with such a set up.

Fitting an air filter to the end of the motor will reduce fan noise, just a simple affair with a few layers of mesh and open fabric still allows plenty of air flow with massively reduced noise.

Thread: Spring Calculation
02/02/2019 11:19:28

I find an old copy of Machinery's Handbook more useful, it even gives you good starting points for mandrel size/finished diameter for a wide range of gauges of piano wire.

Thread: Testing for isolation
02/02/2019 11:14:43

No one here heard of or have a Test Lamp?
You can choose the load to suit your requirements and unlike a volt meter it shows you have current delivery capability and not just leakage.

Thread: Tinhat warrior trademark.

Pushing that rock up the hill again Sisyphus? :D
