Early last November I noticed that in two weeks time there was a model engineering show in centre of Cologne in Germany I fancied which would be a four day job ( day to travel , two days in exhib and day return ) .Return flights from Stanstead , £19.93 ; 2 day pass , on a par with English shows ; Cologne airport 18mins bus journey from centre ; nearby hotel cheaper than Travelodge . So then , all looking good UNTIL I checked return train fair Doncaster- Stanstead .....more than 5 times cost of air fare ! Killed trip stone dead .

Kiwi , You may be interested in visiting the site of D&J Workholding in Oxon who are able supply ranges of different quality collets . No connection with company other than a very satisfied customer. Trevor .

Many years ago , when the rear wiper motor on a VW Polo belonging to a work colleague failed I agreed to fix it for her . At that time it was a dealer-only part and so ordered one from local VW dealer . When on collection I complained at the £105 asking price I was told that if I thought that was expensive , then to remember that the same item was fitted throughout the VAG range ,and that the price increased according to which vehicle it was fitted to .

Quillstar ( Nottingham) Boxford VM30 £1250 ; Emco FB2 £1750 ; Emco Mentor £1450 . Trevor.

Steve , Bit of a long shot , but although he's now retired from the model engineering business , Mr Jackson of Arrand ( 01664 454566 ) MAY just have one of his excellent spindles available from his old stock . Trevor .

Mark , Sent you a PM . Trevor .

I find Double TT by Tetrosyl much more versatile , better at the jobs it does and cheaper than WD 40 .

Use Technifast drive pins of they are not to be removed . Trevor.

Stephen , I have a Vertex rotary table and am generally pleased with it . Please be aware however , there were some mistakes in the division table , but corrected versions have been published . Not sure if this situation applies to the BSO product .

c_b . Given the properties of the various materials you will be using , what fire prevention measures will you be installing please ? Trevor .

Andrew , Malcolm of Myford Beeston told me you could not regrind the bed because ,unlike the 7 series , the cast end bracket would not allow the lead screw to be repositioned following the regrind . Must admit , I didn't question it but simply took his word for it .

Ignatz , Maybe worth seeking the opinions of the 2 ex-Myford service engineers who have been mentioned several times on this site , assuming they still working ?

Muzzer , It's rare to be so appreciated , thank you . Trevor.

Patryk , Just to throw a curved ball into the mix and to give you food for thought , Axminster Power Tools sell similar machines to Arc plus have a usefu page of information to help with milling machine selection . Also , Quilstar near Nottingham usually have a good selection of used , value for money machines available . No connection with either other than as a previously satisfied customer . Trevor.

The turning of an ellipse is a regular feature of ornamental turning , and is usually done using a Holtzapffel Ellipse chuck or similar . Search the above terms to yield a wealth of information .

Ripmax sell 27Mhz crystals , which are available from many model shops . Their web page lists local suppliers .

Component Shop may even suggest 2 of these units connected in parallel and fed through a P103 Power Board ( £14.50 ) , which is available from their associate company , Action Electronics . Though since I am not electronically minded this may not be feasable .Trevor

May I suggest you speak with Component Shop ( 01248 719353 ) . They produce 2 high power voltage reducers ( 10.5v/40v or 16/40v input) each of which will easily give you the 3 volts and will handle up to 7 amps (8amps with addition ventilation ) and they only cost £8.95 each . They may even be able to supply higher capacity units to order . Hope this helps . Trevor

The quality of my Groz is absolute rubbish . As soon as I tried to work it with anything of substance both the rack and the clamp plate bent so easily that it went straight back in box , where it has ostensibly remained ever since . Must get round one of these days to slinging it into the scrap bin .

In the past I have found Mashlin Friction of Sheffield very helpful . I have no connection with the company .

Trevor.

I would suggest you also talk with Direct Drives on 01623 720710 . They also have a useful web page . I have no connection with the company .
