Thread: VFD and screwcutting
16/10/2019 17:38:49

I looked at Newton Tesla, then got a 2nd hand Mitsubishi VFD (same as the one used by Newton Tesla), a quality 2nd hand 3 phase motor and a prewired control box off eBay for £30 - saved myself about £200 and got the same result. I had to program the VFD but that is pretty easy once you get the hang of it and read the manual.

If you work out how to program the VFD it then becomes obvious how to wire in extra microswitches and tune it to the speeds that suit your lathe and the work you are doing.

Its a big improvement.

Thread: Newall DRO
15/10/2019 08:51:15

Not a Newall or a Bantam, but when I fitted a DRO to my Denford lathe of similar size I had to fabricate brackets out of angle that stick out the back of the cross slide. The included brackets didn't really help. There just isn't enough space otherwise. No problems with the z axis but I had to drill and tap holes in the casting.

It's stating the obvious but I fitted spring washers and used loctite to all fittings as I found vibrations loosened the screws over time and scales lost accuracy as the fixings had some end play.

Thread: Changing internet providers
12/10/2019 23:50:26

Rapidly changing technology and broadband demand means that superfast fibre is going to be needed across the country - a house with a couple of TVs streaming 8K movies, the kids listening to lossless streamed music and playing the latest Playstation game requires a huge amount of data that the old BT copper lines can't support.

It looks like the Sky email address will continue to work indefinitely - **LINK**. The reason for that is it would cost more in admin costs for Sky to delete it than the fractions of a penny it costs them annually to keep it running.

Do you have an Android mobile phone? If so you will already have a gmail email address. If not it is is easy to create one or a yahoo email address - or there are many other free email providers.

If you do want to change your email address on the various sites you use each site will have a way to easily do that - e.g. on this site it is settings => my account from the top menu bar. Changing your broadband provider shouldn't have any effect on the way you log in to your various websites and forums - your user name and password won't change (even if your user name happens to be your Sky email address it is unimportant if that is still a valid email address or not). In fact you can't change your user name on many sites. e.g. if your email address is old.mart@sky.com and your username on a site is old.mart@sky.com you can change your email address any time you want say to old.mart@gmail.com but your username will always be old.mart@sky.com - they are 2 different pieces of data that just happen to have the same value when they are first created.

What I would do is set up a new gmail / yahoo email address, then create a rule in your Sky email system that forwards on new messages to your gmail address - that way you won't miss any emails. Then stop using the Sky address and gradually update your email address in the various websites you use. At some point you won't get any new messages to your Sky account and you can forget about it.

Thread: End mill for EN16
07/10/2019 22:21:23

The inserts I am using are Iscar APKT 1003PDR IC908

07/10/2019 12:51:56

Thanks Dave and Andrew

Feeds and speeds is probably an issue. For the 2 insert 16mm endmill I am running about 1200 RPM and 70 mm/min with a cut depth of 0.5mm and less than half the diameter of the cutter engaged - is that just too cautious? This is on a Seig KX3 CNC milling machine. Ideally I would like to use flood coolant but the job is quite high off the table and unless I build a cabinet it will make an awful mess.

Thanks Emgee - I will see what is available and give it a go.

Hello all, I am doing quite a bit of milling of EN16 steel with a vertical milling machine. HSS end mills are going blunt very quickly, I also have a 2 flute 16mm Glanze insert end mill. Can anyone recommend some end mills that will give a good surface finish and last a long time? Any advice is appreciated? Andy

Thread: Versatool cabinets
24/09/2019 08:13:00

I got one fitted out for a jig borer with felt lined trays. It felt a bit sacreligious but I removed most of the wooden dividers and use it to store drills, milling cutters, chucks, collets etc all neatly layed out. It saves so much time having everything to hand rather than hunting through boxes.

Thread: Solvent for degreasing engine, without damaging the paintwork?
22/09/2019 09:39:00

I use a product called Swarfega Jizer. It degreases and protects against rust. It is also water soluble.

Thread: Complete newbie question - RC car from scratch
20/09/2019 19:21:10

Neil, I had a Tamiya as a kid too - the pick up truck, it was very fast but the suspension and steering always needed fixing. You can get them now but they are very expensive. I not sure what happened to mine, probably got sold when I left home.

Chris - good luck.

Apologies, I should have read the full thread before commenting.

Hopefully your friend can get it sorted.

Mark, I don't want to sound mean or anything but why cant your son buy and run his own car? If it has broken down bring it to a garage and they will fix it. If it is uneconomical to fix then scrap it. If you own a banger and it has a major mechanical issue it may be uneconomic to repair it. That's the downside of owning a cheap car. If you want a reliable car that won't cost anything if it does break down get a new one or one under warranty. Andy

Thread: Ebay site changes for the worst
18/09/2019 10:58:11

That's not a scam, its a feature of eBay where you can offer a group of people a special offer.

I think you can can still get bargains on eBay auctions sometimes, if it is a non-business seller. I just got a really nice pair of vintage RayBans in perfect condition for £25. If its a very popular or rare item, auctions sometimes sell for huge amounts.

Thread: Any interesting lathe projects for beginners?
17/09/2019 08:21:29

I made a couple of small machinist jacks when I first started which I actually use a lot. They involve screw cutting, taper turning, boring and knurling - so a good range of skills needed.

Thread: Seeking advice on suitable lathe
09/09/2019 08:52:49

I think if you are doing it on a regular basis using a very small lathe would be slow and get tedious very fast. You would be spending 90 minutes doing a job that should take 2 minutes. Do you have any space to have a larger machine at all? Do you have a garage or shed to put a lathe in?

1 option is a smaller CNC lathe like a Denford Starturn. It would be slow but at least you could do something else while it worked away.

Thread: Disposal of workshop contents
03/09/2019 07:52:40

I would have thought if your friend wants to get the most money - which makes sense if he is retiring - he should list on eBay. As he isn't computer literate maybe a relation or friend can help, or just pay someone he knows some money to help photograph and list the items.

What about simply selling your house and renting?
