Adrian , Look at web site of Home and Workshop Machinery , then under Miscellaneous. Plenty there at bottom of page and at very good prices . Usual disclaimer , just a satisfied customer . Trevor

I got various pieces of pb in stock , but unsure of specific grades . If you PM me your requirements l will check and let you know if l got anything suitable . Trevor.

Jez , Look at " Clearance" on Tracy Tools web site . Also , l have a blade ( may be used , l can't remember ) in stock somewhere . If you PM me your details , l will post it to you if you feel it will help you along . Trevor

Ken , I also have a Brooke motor available , complete with a new quality start/stop/reverse switch , which was removed from my recon S7 shortly after l bought it from Myford Nottingham in order to fit a Newton Tesla VFD assembly . If you're interested , can email you pics . Trevor .

For blotting paper I would suggest trying Jespers in Harrogate , Castlegate in Wetherby or Fred Aldous in Manchester , Leeds and Sheffield .

Chris , According to the Kennedy brochures , the motor bearings are indeed ball bearings , though they do not describe a lubrication schedule for the motor . The secret with electric motors is not to over-lubricate . General advice is to use NGLI ( National Lubrication Grease Institute ) grades 2 or 3 , with a viscosity of 100 -150 cSt . More detailed information is available from Mobile . Have tried to find the icon to insert a link , but failed miserably am afraid , but hopefully will be able to email info to you if you feel it would be beneficial to you . Trevor.

John , just a thought , but since they are doing it every day , what cutter/backing mat / method of use combination does your local frame shop use ?

If you Google "pocket knife manufacturers sheffield" you will find a number of practicing little mesters who may be able to help Some used to work out of Kelham Island Industrial Museum in Sheffield .

John , In case you didn't know , the 10A blade is the lightest straight blade that SM produce and is designed for their No3 handle . If your handle is able to accept different straight blades , l have some larger ones available to fit the No 4 handle , as well as some to fit their craft knives , and if you PM me your contact details , l can supply a couple of each for you to try . Trevor

Steve , Ever considered submitting your work for possisble publication ? Trevor.

Chris , When l worked for Intal in Sheffield ( then part of Clarkson International ) the points on our drills were produced to within a concentricity tolerance to the lands of 0.003" , thus , under certain cirmstances the drill could drill up 0.006" over size if the point was at its limit of eccentricity , with the body of the drill being ground to tolerances of +0.000" and nominally undersize by a small amount dependant upon diameter . The drills were also subject to strickley controlled heat treatment regimes . All these factors contributed to the finished product's accuracy , hence the reason why ours , and our other direct Sheffield competitors such as Presto ( Easterbrooke and Allcard ) and Dormer were so expensive

In the past l have noticed an eBay seller , steevb, who seemed to have an interesting collection of BA nuts and bolts .

H S Walsh and Son normally stock both hard and soft engraving waxes .

Michael , Wonder if those kind and knowledgable people at Bulgin would be able to help ? Trevor .

According to my Tracy Tools wall chart that is a UNEF thread , and their recommended tapping drill is 16.25 mm dia .

Jonathon , Also suggest you consider contacting any vintage groups in your area concerned with mechanical equipment such as say industrial museums , car clubs , motor cycle clubs , preserved railways , vintage lorries club , model boat clubs , Men in Sheds etc . Trevor.

I would suggest you talk with Surtech on 01213594322 . I have found them extremely helpful plus they have lots of info on their web page . No connection with company . Trevor.

I find the smaller sizes of shrink tubing availabe from numerous model suppliers works well for me .

Good old common Domestic bleach does it for me .

Proops are doing a 1 1/2" drill press vice, H4078 for only £18.10 .
