|Thread: Presumably this is done using CNC... but even so its impressive|
|Thread: Cheap DRO for Mill|
Cheap scales don't give you the basics for a DRO on a Mill, if you don't have multiple zeros then you don't have a DRO and you might think it's great because you will simply not understand the advantages to having multiple zero points in 3 axes.
|Thread: Does anyone know where I can source a Myford 34t change gear?|
I've cut my own with off the shelf cutters, presumably the pressure angle for those didn't match either.
|Thread: Simple and accurate home "switch"|
A pair of proximity switches in series with on the linear movement and one on the screw driving the linear way would give excellent positional repeatability and long service life.
|Thread: stepper driver|
Things can be easy, it's just that things are rarely Cheap AND Easy!
|Thread: Hemingway spindle speed increaser|
My FB-2 will run in reverse, great for reversing out taps etc. but since the oil pump is a helical screw connected to the motor shaft you wouldn't want to run it in reverse for any length of time.
|Thread: Knurling speed|
John Stevenson once proved, by knurling a taper, that calculation for formed knurling is not required for adequate engineers
No, it's caused by knurling a material which can not cold flow as far as would be required for a full knurl.
|Thread: New Toy|
Yeah, it's a shame they went through that learning process, I'm pleased to say that my X7 is as square as my DTI is able to detect and is astoundingly rigid, it almost puts the wind up you the speed it shifts material! :D
|Thread: Soft Feel Finish on Radio|
Acetone cleans it off quite quickly although might affect the base material - always do your test patch!
|Thread: New Toy|
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.

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!
|Thread: New Toy|
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.
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?|
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|
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|
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.
