Thread: Burglar alarm

Good idea, make sure that you audible alarm complies with the regulations regarding length of time sounding etc. You don't want the council noise snoopers spoiling your day.

If I'd known that you were trying to level up this years Christmas tree.... , no, maybe not that simple.

Good luck with your endeavours.

Would laser cutting be an option?

Thread: Pulley Size calculation
06/03/2018 17:42:36

Get in touch with a drive line supplier who will help with both the sizing and supply of the parts.

Someone like Brammer might be a starting point....

Thread: Expansion Plate Mechanism
06/03/2018 17:36:40

How big is the pipe?

Size matters when you are looking for a solution.

Is there a fluid inside the pipe?

More data required please, we can't see from here.

Thread: Myford Super 7 Lathe Instruction Manual
06/03/2018 17:32:54

Beginning to wish that I hadn't started this thread now.

Perhaps the moderators ought to delete this thread to protect the forum from any claims that might present themselves if that is the consensus of the posters here.

04/03/2018 23:29:53

This may be already to hand for Super 7 owners but I came across a download for the operating manual which may be useful to some. It is a pdf.

Apologies if this is old news.

Thread: Oiling a Brook Compton Parkinson electric motor on a myford lathe
04/03/2018 23:01:52

A couple of drops now and again should be okay, the oil keeps a felt ring lubricated.

This Indestructable may be useful.

Thread: how do i make a sealble interface
04/03/2018 14:09:47

Get standard sink waste plumbing fittings.

32mm is 1¼"

You can get adaptors to go from 32mm plastic to 22mm.

Use Plumbers Mait to seal waste fittings to sink outlet.

Using the manufacturing techniques Myford used to use you might see why 8k was the price to the customer.

But with the 'new Myford' it's difficult to see how it's ended up the same price. For sure it's a lot more 'complicated' than a boxy relatively rough piece of cast iron from the far east, and it's almost certainly better finished but it's one hell a lot of money for not much metal. It only comes with one chuck and is powered by a 0.75kW motor.

But it's not actually '8k' its actually 8150 + VAT

A staggering £9780

To put that in perspective for 30k (plus VAT) you can buy a very capable (far east built with UK support) 3 axis CNC vertical machining centre with an 18" x 14" x 14" axis travel, an 8k CAT40 spindle with a 7.5kW motor (machine weight 2.6 tonne) or for that same 30k (plus VAT) a CNC turning centre that will swing a foot diameter, a foot long, with a 12 station turret, with a 6000rpm spindle powered by a 13kW motor (machine weight 3.2 tonne)

Of course neither of those will sit in the corner of a tiny shed but 9780 quid for just 180kg of machinery? That's 54 quid per kg or £24.50 per pound or £1.50 per ounce

If you have to explain a joke then it isn't funny.

Thread: Unidentified Rule
26/02/2018 14:52:43

Slide rule forerunner perhaps?

Damn clever our forebears weren't they?

Thread: Silver soldering.
24/02/2018 22:04:18

Is foil the same as tape?

If so then CupAlloys sell it.

Thread: Mig gas pressure ,what happened ?
23/02/2018 19:04:47

Sounds like you might only have a single stage regulator. The outlet pressure can change as the inlet pressure falls.

A two stage regulator would avoid that problem.

Thread: Making brass and bronze
22/02/2018 19:53:00

Bronze is an alloy mainly if copper and tin.

If you trust Youtube then there are a fair few clips showing how to do it.
