Thread: What to buy at Ikea?
26/01/2018 23:56:04

The Jansjo lights are good but I find that the arms sag under the weight of the lamp. A rough and ready cure was to wrap the arm in masking tape and when in the ideal position, a few drops of super glue holds them in place. If necessary, there is still enough give in the reinforcement to reposition the lamp.

Thread: How effective are phase converters
07/01/2018 16:57:42

Most machines can be powered by 1phase - 3phase Variable Frequency Drives (VFDs), with the VFD wired into the ring main, provided the motor power isn't above about 3h.p. I have 3 VFDs: 2 driving 3 h.p. motors are wired separately to high current circuits (30 amp breakers) and the 3rd with a 2 H.P. motor is connected to the normal ring main.

Cost of a VFD is not a lot, just have a look at eBay. One possible disadvantage of the VFD route is that you will need one VFD for each motor, but still probably cheaper than getting the local electrical board involved.

Thread: Recommendations for a quality milling vice?
30/12/2017 15:08:14

What size of jobs are you wanting to grip?

A lot of vices don't open particularly wide, so one suggestion is a built up vice from Darmet. https://darmet.com.pl/en/vises/1652-precision-machine-vise-fpzb.html

A possibility for long items is an endless vice such as eBay 292217124620 (But I wouldn't want to pay that sort of price for something that is quite easy to make!)

On my Wabeco mill, I use a Warco DH-1 vice and am very pleased with it.

Thread: How quiet are silent generators?
25/12/2017 17:59:22
I've considered getting an emergency generator for when power cuts occur. Originally I looked at the 'suitcase' types, but they are quite expensive for their modest output.
My present consideration is similar to eBay 272527775595. Not quite as quiet as the Wolf model but a more useful output (for me) and the fact that it will be used outside (but stored under cover) negates the noise reduction.

Thread: Wife impressed
19/12/2017 22:49:25

While I admire the service of some advertisers, especially ARC frequently mentioned, isn't this a sad reflection on the others who fail in the customer satisfaction stakes?

Don't the 'under-performers' realise how much potential business they are losing? Praise for good service is hard to get, but unhappy customers are very quick to let others know of their dis-satisfaction.

Ken

You might consider advertising your service on Model Engineering Clearing House. As far as I know their service is free. How much response there is to any of the adverts, I know not but it might be worth a try.

Thread: Lindsay Publications
06/12/2017 10:06:13

Subscribers to the Yahoo group for 7 x 12 lathes will already have read the following, but for others this may be of interest:

Since 2013, Your Old Time Bookstore has been selling off the remaindered technical publications produced by Lindsay Publications, which closed when Lindsay retired. Now they're reaching the end of the inventory and are closing on December 31st. There are still many good books left, and I urge anyone here to visit it who's interested in machining, boating aircraft, old-time radio, and a host of other subjects that Lindsay produced books in. **LINK**

I bet Tony Griffiths at lathes.co.uk would be very interested in your tool - and may well be able to help with more details.

Thread: Carbide Parting tool
30/11/2017 13:07:49

I contacted Sumitomo for their advice and they informed me:

Hello David

Re, your recent request regarding part off blades / inserts
99% of manufacturers parting is captive, which means only their inserts will fit their blades.
Sumitomo are currently offering a package of holders and inserts.
Please contact Paul at STS Tooling (Dublin) for more details
Regards
Andy
 
So, anyone with a similar dilemma now know the answer.
Looks like I will have to dig deep in the pocket for a blade to take GTN 3 inserts. There seem to be several manufacturers for these inserts, which would suggest that Sumitomo want to keep their system all to themselves.

I have just ruined my parting off tool blade type SGFH 26-3. I have a number of spare GTN 3 inserts so don't want to change types.

New blades can be quite expensive, but I have seen a brand new Sumitomo blade for not a lot of cash. However the designation is STFH 26-3.

Question: What is the difference between SGFH and STFH blades?

I've looked through the Sumitomo website and they state the insert for STFH is WCF. Is this the same as GTN types? (They look the same in the pictures!)

If my inserts are compatible with STFH I will go with that type of blade.

Thread: Early myford super Seven parts identify plz

Piero Franchi:

Congratulations on your "full restoration" - I assume this is not one of those situations where you have left over parts and don't know where they should go!

As an aside... The engineers on board would sometimes play tricks on their mates when an engine overhaul was being undertaken. The usual thing was to hide a couple of bolts before rebuild, but an evil one would throw in an extra bolt, causing a bit of head scratching for a while.

Thread: Gearing Myford S7

Thanks Rod

Should have studied the chart more closely. And I've had the cataracts removed !

Question for Rod - or others:

The smallest metric pitch with the simple gear change a al table above is 2.0 = M15, which is quite coarse for my likely usage. Is there a way to cut smaller pitch metric coarse threads with a simple gear change? M10 - M2 is probably the range I would likely need to cut. OK, M2 - M5 would be by dies, but it would be good to know if it could be done.

Thread: The true cost of Diesel?
06/11/2017 15:04:34

Posted by not done it yet on 06/11/2017 13:19:46:

but the reality is that the technology doesn't yet exist to permit long durations without recharge,

Wrong again, I afraid! It does exist. The French have recently demonstrated an 'on-the-go' charging system that can supply an electric vehicle with 20kW. Sufficent for a reasonably sized car to travel at the speed limit.

Installed on through routes/trunk roads/motorways it may well offer the long distance traveller to travel considerable distances without needing to recharge at a static charging point.

Only one problem there: what happens when you are parked up in a traffic jam on the motorway with stop-go for 15 miles or more and you are low on battery power?

I came across this the other day:

**LINK**

Where I live Diesel is only about 2 pence a litre more expensive than Petrol ... Not withstanding VAT and Fuel duty I wonder why Diesel is being sold so cheap or am I missing something?

Over here in Ireland, Diesel is 10c / ltr cheaper than petrol.

About 12 years ago we were all 'persuaded' to buy diesel vehicles because of the evil petrol pollution. Now the Greenies want to bring the cost of petrol up to match diesel because of the evil diesel pollution, and they wonder why they don't get any votes.
