Thread: Yaskawa VFD
30/04/2019 12:23:03

I have several machines with vfd up to 2.2kw and all of them are fitted with a 3 pin plug and 13 app fuse. None have ever blown the fuse nor tripped the 32a mcb in the panel.

Second from the right is a globe valve seat cutter.

Thread: Does anyone know where I can source a Myford 34t change gear?

Posted by Adam Stevenson on 29/04/2019 18:13:03:

I don't think it matters who makes them, marypoppinsbag sold them on ebay and myford tried to get them banned but as it only stated they was Myford compatible no one owns the right to make them or sell them. When Lesley died JS sold them to RDG as well as the few direct customers. You are welcome to list the on HWS.

Thank you Adam, for that consideration. If remember John saying that they tried to get Lesley's advert pulled.

It wasn't my intention to get into wholesale, more to fill a need but if they continue to remain unavailable I may advertise some in the future. More than half of the above sets are already claimed.

As David rightly put it's difficult to get off-the-shelf gears at 14.5PA

These have been out of stock at the usual outlets so I've made 7 pairs and been given leave to list them in the classified section this one time due to the lack of availability. They are steel gears with hobbed teeth and broached keyway.

28/04/2019 16:35:03

I'm going to hob a few pairs of these gears since they are not currently available and I want to raise some funds to get a DRO for one of my machines.

Thread: Another question about gear calculations!
27/04/2019 21:10:29

Adam,

If you want original 22DP 20PA gears I can hob them for you. You'll have to furnish me with the relevant dimensions i.e bore, thickness etc.

Pete.

Try finding a 48 tooth gear. They are even more difficult to get hold of !

48T is not part of the normal set. What is it required for on the Myford?

Thread: Cheap DRO for Mill
19/04/2019 11:01:51

My Chinese DRO has error compensation facility. I never had cause to use it since the DRO is more accurate than the machine's rigidity allows for, but if you were so inclined you could map the scales with jo blocks or indicators and apply the compensation in the DRO.

Thread: How much can a chuck effect finish?
18/04/2019 17:02:53

Could be bell-mouthed jaws or it could be a raised burr on the rear register. If the back of the chuck doesn't seat firmly on the spindle all the way round then it'll rock on the threads when you put a cutting load on it.

Thread: Stainless steel lathe drip tray for 30
16/04/2019 06:34:10

Darren can you link to the actual item please? The 5 yr old link above is long dead and I have tried searching the Ikea site but not found the thing you're referring to.

Pete.

Thread: Does a 1600rpm bantam have a single v belt?
14/04/2019 23:54:48

I put a 3hp motor on a Bantam with a single belt and ran it up to 1600rpm on the VFD no problem at all.

Thread: Lathe on machine feet
14/04/2019 19:13:31

A single m8 bolt 8.8 grade will hold 2 tonnes, a 12.9 will hold half as much again. Using M12 is not necessary if it makes lining the holes up tricky.

Thread: Problem with penetrating oil can
12/04/2019 18:31:36

I use brake cleaner pressure pot dispensers. They are about £15 each and last for years.

Thread: Jacobs Gear Hobber
09/04/2019 19:07:31

The manual for my hobber (which uses 32mm diameter hobs) says the hob speed is 300rpm for steel and 980rpm for brass.

Thread: Colchester Lathe Dials
05/04/2019 15:13:32

Could be that it once had a twin-start cross slide screw but someone made a new one with a single-start thread of the same pitch (as often happens on the Bantam/Chipmaster lathes). It turns the screw from radius to diameter-reading and the dials still make sense (once you've figured out what's happening).

An easy way to tell if that's the case is to use a dial gauge to check the feed rate on the cross slide when surfacing. If you turn the chuck one turn by hand and it only feeds half what the levers are set to, that's an indication of the above.

Thread: Know of a good lathe bed grinding firm?
31/03/2019 14:02:18

Slideways packed up at Christmas. Some guy down in Kent has the machines now.

Thread: 4" chuck backplate
24/03/2019 13:11:20
Posted by Martin Shaw 1 on 23/03/2019 20:58:03:For the record it was turned at 800 rpm with a 10thou DOC, I was going carefully but I reckon you could double that confortably. Apart from the smoke I don't know whether cutting oil is beneficial, but the swarf was coming off in long unbroken twists suitably blued by the heat, I certainly didn't appreciate just how hot.

Regards

Martin

Way, way too fast. You should be turning that 4" diameter piece at closer to 100rpm than 800.

Thread: What is a good quality lathe paint
19/03/2019 16:36:40

I had my lathe cabinet sand blasted, but no other part of the lathe. Hopefully you understand what bits absolutely MUST be protected Grant.

Apart from that any good enamel paint will do the job. I use Arcforce enamel off ebay along with their grey zinc phosphate primer.

Thread: Help please, I have a Herbert
15/03/2019 18:28:02

Damn necro-thread. i didn't spot that either

15/03/2019 18:00:02

I have a 0V, it too had a proprietary taper with just 6 imperial collets so I sent the spindle to John S and he re-worked it to take R8 collets. Now I have no problem finding tooling.
