Thread: Health

I understood that this forum is for the sole subject of Model Engineering, not including medical items and least of all, blatant medical company advertising, For Free.
I think David should take this down at his earliest opportunity.
Thread: So, now i have removed the Clarkson chuck should i stick with it?

nic,
If you keep the Clarkson chuck, cut a `washer` of thin flat plastic to fit inside the damping ring. I used a cut out of the red plastic lid on Nescafe tins. Should you get that damping ring jammed up tight, it will be much easier to undo with the plastic interposed.

You could also use Green Hermetite as a gooey sealer - it never sets so easy to unscrew fittings. Do Not use Red version - it sets solid and hard.

Bogs, you must be having a laugh - do you seriously believe that any one in the print trade ever proof - reads anything these days? It certainly doesn`t look like it, judging by all the errors/spelling mistakes and words badly split mid-syllable betyween lines. This is not a dig at DavidClark1 - ME/MEW are pretty good but "the daily rags" are the worst culprits.

I remember the West Countrys on down trains from Brighton, stopping at "Portslade & West Hove" station when Iwas a kid. Did they clonk, some of them.

Thread: Milling drawbar
18/07/2011 20:41:54
Re Dusty`s post today. My milling chuck doesnt work loose as I use the drawbar to hold it secure However, on occasion, it has stuck tight but with my new drawbar as previously described, it is no problem to remove. I have used the tang - ended tailstock drilling chuck in the mill spindle to drill holes and its come down. Ido clean my tapers internal and external. I use a piece of soft cotton cloth to draw through, like rifle barrel cleaning.

Dusty,
Its well known taht a 2MT will part company under a milling load. I have had a 2MT tailsock chuck in mill for drilling holes + thats come loose. Mill or drill chucks just want jamming in by hand and drawbar gently tightened to prevent disasters. I find that Clarkson chuck some times gets stuck fast, possibly when using big (5/8") endmill or slotdrill, ss needing my type of drawbar to shove the tapers apart. BTW, I dont claim originality for it, I read a description of this somewhere - just passing on my knowledge.

I believe that SMEE used to have a Myford on loan to them for their MEX stand but M now gone, so what now? Presumably a member will bring his along.
Thread: Milling drawbar
15/07/2011 01:05:03
Hi Pat,
I used BMS round bar, NOT Silver Steel for my drawbar. Sil. St. not necessary. Bottom end threaded to suit MT, top end same thread as for the MT. When finished, there is a nut pinned to very top end, along piece of large - AF Hexagon bar, part - bored out to fit over top of mill spindle and locked on to it with 3 grub screws fitted radially and top end is bored out to a clearnce size for drawbar. Another nut is fitted to draw inside the large hex. bar, so its trapped. When the top nut is turned clockwise, it screws thro. the trapped nut and bottom end screws in to MT, drawing male taper into female taper in spindle. Dont over tighten - just nip it up to secure it. When top nut is turned anti - clockwise, drawbar unscrews thro. trapped nut and from MT. The trapped nut wants to stay put and rise up with the unscrewing of the drawbar from theMT but its trapped and cannot move vertically thus preventing drawbar from moving vertically. Something has to give and its theMT shoved down, breaking its grip. Is this now all clear? Hope it helps.

Look up "Milling collet arbor jammed in milling machine" of 4 June 2011, in Forums.

Agree with JasonB, regarding make your own drawbar but Paul should go one better and copy my previous post describing the trapped nut which forces the MT apart gently instead of a hammer/brute force, wrecking bearings in the process.

Thread: Classified Adds

I cannot understand the need to use twitter or facebook when we already have this forum to discuss things. From what I have read, facebook appears to be a security nightmare and I`m reluctant to use it. I do read other mags, e.g., Computeractive to keep up with whats going on.

Wow! Since my earlier post around 11.30, I can now go in to For Sale or wanteds and they`re all presented as they should be. Thank you David.

I have had the same over-written ads prob for a long time. Complained but no listens! Wots new?
Have given up trying, just do same as "Weary" and all is fine.
Just seems a pity that it cant apparently be sorted out properly.

Hi Adrian,
Watch out for that green dust. Even if its not carcinogenic, it will still do you no good to breath it, or ANY other dust. Use a mask, including when you`ve finished and sweeping up.

Thread: Subscription question

I did exactly the same as Bob Lamb earlier this year and had £50 taken. Was going to complain like Bob but never got around to it as I thought that it looked to good to be true and almost certainly referred to the online price, so did not do anything. Thought it was a bit of a cheek though, the way it was done. Misleading Advertising.
