Thread: "Screwing" a car round a corner!
28/04/2019 07:02:13
Posted by Jon on 27/04/2019 22:16:17:

Common knowledge RWD with power on induces over steer controllably.

Common knowledge FWD with power on induces under steer and no control.

We used to do “left foot braking” in our FWD Minis. Hit the corner fast, turn the steering hard, and hit the brake whilst keeping the accelerator pressed down. Drive would keep front wheels turning (helped by fairly average front drum brakes), rear wheels would lock, break traction, and rear of the car would hang out. After a bit of practice it was fairly easy to control how much the rear hung out by adjusting pressure on the brake. Best done in the wet. Apparently it was common practice in rallying, I got put onto it by a mate who raced a Mini in rallys.

Thread: Moving to Australia - Moving Workshop Machines
18/04/2019 02:46:04

Don’t take TV's with you. I’m not sure about Australia, but here in NZ the gap between picture and sound frequencies is different from the UK.

i ended up being able to tune into sound, or picture, but not both at the same time.

Also as Peter said, fridges don’t seem to last out here due to climate. Ours worked for about a month.

I bought a load of UK electrical plugs and sockets, and have most of my tools fitted with UK plugs which are more robust (& fused), and have UK sockets in the workshop. Any new tools I buy get their plugs replaced with UK ones.

When I moved from th UK to NZ, I ended up getting a container. The cost was about the same as shipping a few individual items. Went with a 40 foot one in the end, as the total cost wasn’t a lot more than a 20 foot, and it saved making tough decisions about what to take and what not to take. It also meant I had an excuse to buy a load more stuff as it wouldn’t have been sensible to send it only 3/4 full.

I've never regretted it, just wished I bought a few more tools before I left, as the selection on decent stuff here is more limited, and prices are much higher.

It's quite a lot of time and work trying to source decent quality replacement tools if you leave it behind, much better to keep the tools you know and trust.

you could always buy some stuff before you leave and sell it for more in Brisbane to subsidise the cost of a container.

Thread: Old screwdrivers - any use as a materials source?
04/02/2019 23:16:17

I've used old screwdrivers as handles for welding hammers (for chipping slag off weld when arc welding). Head is just a bit of mild steel (or whatever is sitting around) welded to the end of the old screwdriver.

Thread: Milling for beginners

I’ve been surprised at how much better spiral taps are than standard ones. I only have a few metric ones, I’m not sure if they’re available out here in Whitworth, but guess if they are they’ll be prohibitively expensive.

I've never broken a spiral tap, wish I could say the same about standard ones.

Hi all

I bought these two tools at the weekend.

I’m not sure if they are for use on metal or wood.

looks a bit like an end mill, it won’t drill holes as it leaves a nipple in the centre like an end mill.

The other looks like it's for counter sinking?

They are both “Louis Eichman”, but google seems to give loads of info on a famous war criminal and little else.image.jpeg

Thread: Cost of deliveries
11/12/2018 21:15:53

I’ve bought a few items from the UK where they don’t charge VAT (as it’s an export to outside EU), and freight cost is only a bit more than the VAT. It does seem to depend on weight.

I have found some sellers have really high freight charges but guess they don’t really wish to get into selling overseas.

I still don’t understand how Aliexpress sellers can do free shipping. Often I can buy items with free postage from China for a fraction of the cost I can buy exactly the same thing locally.

Thread: Cheap carbide inserts - where's the market?
30/11/2018 18:42:20

I like the cheap carbide inserts because they are cheap. As an unskilled beginner I've chipped quite a few inserts inserts. I’d rather destroy cheap ones than expensive ones (have done both). I’m starting to get better at with practice, and maybe when my skill levels are higher I’ll start using the expensive ones I’ve got in the drawer.

It would be tempting to blame poor results on cheap inserts, but find they're lasting longer and performing better with practice.

And a complete chapter on making your own fireworks.

Don’t see that in modern books

Thread: Machine light
05/11/2018 04:06:46

You may find you can sell the old lamp for more than a replacement costs. They’re quite collectable and sell well on eBay. I looked at replacing the one on my lathe with a period lamp but after seeing the prices went with led

Thread: Dewhurst Switch 3 phase wiring
08/10/2018 08:35:38

Switch is rated 500v 3 phase.

I’ve wired it up and it works, but sometimes it tries to start the motor rotating the wrong way. Motor won’t start if belt on Myford is tight (need to have belt slack to start). Once motor is running it’s fine.

I’m wondering if I’ve got the R, W & B wires going to the motor around the wrong way?

05/10/2018 19:43:08

Thanks!

One section of cable (motor to switch) is older but looks to be in good condition & is in a metal sheath, so I’ll reuse it. Rest is more recent with a green earth wire.

I reckon I should have paid a bit more attention at school when we did electricity.

05/10/2018 08:33:03

hoping someone can help me with wiring up a Dewhurst switch.

I have 4 wires from socket;

L1 - Red

L2 - Blue

L3 - White

Earth - Black

image.jpeg

Dewhurst switch has 8 terminals, 1-4 down one side, 4-8 on the other.

I did have photos of how it was wired (replaced motor with single phase) but can’t find photos anywhere! Now I’ve put the 3 phase motor back on but can’t work out wiring. I’ve had a hunt on the web but can’t find any diagrams which seem to match for 3 phase

Thread: What did you do Today 2018

Nice work David!

I think I’ll make a couple those to replace some knurled ones which really don’t have enough grip.

Thread: New old 1950's Myford 7 Lathe still in the crate
10/09/2018 05:07:44

That auction site pretty much monopolises NZ.

There’s no eBay here, closest is Australia.

There’s even a few UK companies which sell on it

Thread: Kennedy Power Hacksaw Gaiter
09/09/2018 06:55:13

The conrod on mine is the same as pictured above, with only a clip where it attaches to the saw frame. There is some sideways play if you wiggle it, but not when it’s in operation.

The only problem I’ve ever had is a tendency for the large flywheel to move in towards frame, but I think I just need to replace the grub screw which should hold it in place.

Thread: Lubing my new mill
08/09/2018 07:24:19

Thanks, it’s a “Topone” Bridgeport style mill. Pretty much the same as a Bridgeport but head rotates on 2 axis.

Glad I read this thread. I’ve had one of these for years and always thought it was home built.

Where does the gaitor go? Mine has none. Also, is the tube with the damping mechanism meant to be filled with oil?

Thread: New old 1950's Myford 7 Lathe still in the crate
08/09/2018 03:09:15

I saw a oil in frame Bonneville in the crate for sale a few years back. It had changed hands a few times, with only the lid having been removed.

A panel beater and Triumph enthusiast down the road from me bought it so I went to have a look. He wouldn’t take it out as he reckoned the value would drop.

What a waste of a motorcycle, might as well have had a crate full of scrap metal. I kind of understand people having vehicles with only a few miles on the clock as display items. As least they’re nice to look at, but not don’t reckon a wooden crate is quite the same.

Hopefully someone will buy the lathe and use it.
