Thanks Tim. The link won't work on my computer, but it does on my phone,

Yeah , i think you are correct.

Tim, thanks for the link, but it does not lead anywhere.

Emgee, yes i meant to type 1 1/2", seems to be a standard size with boring heads.

I bought a used criterion boring head online yesterday, and am waiting for it to get here. The head is a 76mm/3" one, but has a bt40 shank on it. I want to order an r8 shank for it, would anyone happen to know what threads criterion use on these heads ? I want to get one as soon as possible, does 1 1/4 x 18 tpi sound right ?

Looks like an apprentice piece to me. Very well made, probably made back when engineering skills were appreciated by society.

I bought an er32 r8 taper collet chuck from rdg in november. It was marked myford. On inspection it seemed ok apart from the nut was stiff on the body of the chuck. The first time i used it was holding an edge finder. Found the edge and swapped for an end mill, 4 or 5mm in diameter. Took the cut and went to change to a larger tool, the nut slackened off a quarter turn and siezed solid.

I took the whole thing out of the machine and sent it back to myford. After about a week i emailed them and they told me the reason it seized was i did not know how to use it, the collet had sprung in behind the nut, which couldn't be removed, and they were returning it to me at a cost of £13 !.

Despite the myford name, i reckon they are the usual Indian tat, the nut and the body of the chuck were similar in hardness, galled and seized.

I won't be buying anything with the myford name on, and no more from rdg.

Buy a vertex, or a good, european, american or japanese brand, or see if you can find one second hand on ebay or here.

My Tom Senior is a universal, i have never had the need to swivel the table, but it is nice to know i have that capability if i need it. I have used the horizontal spindle more than once, and i do like the way that large side and face cutters slog through a lot of metal, without a lot of fuss, very quickly. Cutters are cheap off ebay too.

Have you looked for original drawings ? Maybe the Imperial war museum or the Tank museum in Bovingdon could help ?

Yes, i think charity shops pay no rates or vastly reduced rates. Here in dublin, one street that used to be filled with shops, like electrician's shops, tools shops (good ones), carpenters/cabinet makers suppliers (i remember going as a kid with my father as he had to pick up a roll of veneer for the cabinet maker at work), motor factors, is now populated with ahem "adult" shops, fast food joints of dubious appearance, charity shops, bookies and coffee shops.

Very good, i will watch with interest.

Lovely work Bob, for next weeks project, you can whip yourself up a manx norton engine.

Lovely work Windy, please show and tell us more about it.

LOL, show me where i am wrong though ? Its not all bad though, Triumph and norton are making bikes for example, that are better than ever.

Is there a base on the tailstock that is removeable from the top ? There is on my colchester, i think shimming maybe the easiest way to get things back in line.

Well you have met me now. I took a colchester home from work, and regret taking it for free ! Another grossly overrated brand, like landrover, barbour etc. Trading on a history of a name, when their products are often middle of the road at best, and downright junk at worst.

Lovely, tell us about them please.

Well the metric is what you said the AF should be to imperial. 6mm threaded fastener, but a 10mm AF spanner.

I always liked Gordon tools of Sheffield. Someone gave me a few of their spanners and sockets a few years ago, and while they are old, they are excellent.
