Had a PM reply from Roger, copied below.

I've made contact with the outside world ! Thanks for your reply.

My current project is a horizontal mill type engine, 2" bore 2" stroke, entirely made from odd castings and bar stock ,cylinder covers are 80mm c i bar stock, crankshaft an unmachined casting of unknown origin, flywheel Stuart 5a, cylinder Stuart no 1, steam chest brass bar. Eccentric straps brass 3/8" plate. Bearing blocks steel bar. You can see pics on my album.

Hi Roger

Certainly a compact workshop but that hasn't prevented you from making some very nice looking engines, although you say compact it looks very well equipped with tooling.

Welcome to the forum, what's your current or next project ?

Emgee

Don't feel too bad about it Dave, from another site somewhere "The man who hasn't made a mistake has likely made nothing"

Over the years I have to admit spending many hours machining parts that turned out to be scrap, I think that's what is called gaining experience.

Emgee

They seem to have left some spare cable in case the communication cables needed re-terminating.!!!

Only guessing now but the boxes could be metered supplies with some kind of switch/mcb positioned at the bottom behind a hinged cover.

For some reason Craig stopped posting here on his build but the engine is now completed and has been test run.

See it at this link **LINK**

Sounds good and seems powerful by the stats provided.

Nick, 7075T6 is a very good material but supply in the UK is by specialised dealers and most charge high rates.
6082T6 may be OK for your job but a bit more info would help, a detailed drawing would be good but a sketch with dimensions indicated would be helpful.

I experienced the same or similar fault in a Honeywell heating controller, the circuit has 2 relays, 1 for heating and 1 for water, both independently switched as programmed.
If 1 relay was energised there was not enough power/voltage in the circuit to energise the 2nd relay.

Replacing the capacitor in the circuit restored correct functioning of the controller, cost was around £3 as against £80 for a new controller.

You won't get into tight corners using a Straight (Neutral) holder, you will need either or perhaps both RH and LH to reach all corners.

Seems to me they are comparing the old motor with external brush holders to the new motor with enclosed brush holders.

I have searched without success for evidence to support the claim of more power so the word I find for the description may not be within the site rules.

Emgee

Michael

Those links didn't answer my question about getting more power with motor enclosed brushes !!!!

Agreed especially if you add £30-£50 carriage cost to Europe, and it is only 60W output working at maximum 5mins on 15mins off. There must be a better alternative available if you look hard enough.

Emgee

Following the link above to see the explanation for the move to internal brushes that have to be replaced at the factory, could someone please explain how more torque is obtained with internal brushes fitted in the same orientation as external brush holders.

I can see the motor costing less to manufacture with fixed internal brushes but it doesn't help the European user when it comes to checking or replacing brushes.
Seems to me Sherline are making the motor a throw away item with the carriage costs involved.

Emgee

I would have thought the Repair Shop program would appeal to all members on this forum, after all we do practice a craft of some kind whether it be using hand tools, programming and pressing buttons or setting up and turning handles.

As said it is amazing the skills of those doing the repair/restoration work.

Check your Message box Steve, top menu bar envelope flashing.

Many years ago I bought a 1100C Kiln and included with it some whale oil to quench parts which also gives a durable black finish. The other evening there was a part quenched in linseed oil on the Restoration TV program, looked like a good result.

tools below quenched in whale oil.

Not true Peter although Denford did do a small lathe and mill using Sherline machines within Denford enclosures operating with Denford software.

The other cnc mills and lathes in Denford's range are much larger machines than Sherline products.

Emgee

Ron's indicator and mag base now £13-79 delivered, such a good buy.

Emgee

I see you have decided on a good quality tool but my experience using an £11 single operating point 2 armed mag base has been favourable for the cost and adequate for a quick check on concentricity of parts fitted in the chuck, only a small unit so easy to fit on the toolblock,

Dave

I agree entirely with the first 2 paragraphs of your note but being old school I think it is wrong to offer a mill/drill for sale calling it a universal milling machine, dual purpose yes.
Although it may be seen as misleading I don't believe it is intended to deceive, old hands will know the swivelling table function of the universal mill doesn't exist on the machine in question and newcomers will no doubt take "universal" to mean mill/drill.

Emgee

Most likely a good idea to all be aware and report on this thread any listing for sale on any media that has all the signs of being a scam, if the item offered is genuine the seller can provide details to support his/her claim if made aware of the reported scam.
