Hello Stephen, please re read my post, the cutter does not have a multi start thread, and the Deadlock chuck does NOT have a collet. OzzyO.

Now I think that is a bridge to far. OzzyO.

Hello Stephen / All, a very good reply, but I must question you about the above quote. That sounds like you are describing the Clarkson Autolock chuck. The Clarkson Deadlock chuck that I used had a collar about 1 1/4" in dia. with a multi start thread in the body that was locked in the closed position by the use of an Allan type of screw (it wasn't an Allan screw but that's how best to describe it). The cutter was screwed on to an extension of the multi start thread using a thread of about 1" dia (internal on the cutter external on the extension). The cutter would tighten its self up as you cut. To release the cutter, you would unscrew the R/H Allan type of screw and then tighten the L/H Allen type of screw. The first screw would unlock the multi start internal screw and the second one would start the multi start thread to move. We always stored these chucks ready to use. One time that I know about a new miller did not check the chuck was ready for use and mounted a cutter on one the cutter was about 2" or 3" Dia. it took about an hour using brass drifts (used against the back of the cutter flutes) and large hammers to free the cutter. So my mate and myself took one apart, it turned out that if you take the R/H screw right out there is enough movement on the L/H screw to unstuck the cutter. Sorry I don't have a photo of one but if you go on EBay and type in Clarkson Deadlock you will see some. OzzyO. PS. the second chuck that you have shown is normally for ER type collets. Not a dead lock chuck. This type of chuck works by friction only.

This may work as long as you are pulling the adapter up in to a taper on the milling head, to use "glue" to hold a milling cutter don't be daft.. The use of a screw to hold the cutter is well known , but it can cause the cutter to run off. The Clarkson Chuck was one of the best ones that I used when I was in engineering as it used the large screw on the body to hold the collet in place then any cutting force on the cutter would tighten the collat on to the shank of the milling tool. If you have worked in engineering you will know the Dead lock chuck as well. now tell me how that works? OzzyO.

Hello Ron, the only reason that I can come up with for the three different colours is so that an inspector / foreman could see that all parts had been painted. How about the wages 1s (5p) per hour, or 1s6d (7.5p) per hour. OzzyO.

Ron / All, just think that if this viaduct was being built nowadays it would all be in concrete with no decoration. I take my hat off to the Victorian designers and engineers. Fantastic work Ron. OzzyO.

So Brian, were looking at 35.5" or just under 21mm. OzzyO.

Hello David, what would the height be to the bottom of the windows from the footplate? And was there a difference in the door windows, steel doors wooden doors? OzzyO.

Thank for that HT. I couldn't remember the full quote, but you got it . OzzyO.

Hows it go? In for me or is it informe, is that how famous that RMweb has become? OzzyO.

Easy mistake to make. Class47s and Westerns are so similar in appearance . OzzyO.

Hello Brian, the Allan key size is 0.035" (0.89mm), I get mine from the local hardware shop, cost about 50p. OzzyO.

Hope all goes well. OzzyO.

Olddudders, don't be so daft she cant afford to sell me, I want to trade her in as I'm fed up with her getting all the TV work! I can see the Mods coming to get me now. [Mod3 - You were right] OzzyO.

Brand new untouched 51 year old male, one careful owner , still in the wrapper. Had him for twenty years want to exchange him for a newer model, or one that's got more cash, Hold on you've got me typing this. OzzyO.

Has it been a free week-end for listing crap stuff? OzzyO.

I'm with Horsetan on this what can one say, if it was 7mm I'd be impressed but in 4mm I'm very impressed. Keep them coming Ron. OzzyO.
