One of the two Worthington-Simpson triple expansion pumping engines at the Kempton Steam Museum. Well worth a visit but check the website to make sure the working engine is in steam when you go.

Yes, I am glad not to be travelling today but it has advantages. Living about 6miles from Heathrow I was standing in the garden thinking "Where have all the planes gone?" Very quiet. Just the one very high con-trail. They can do this every weekend if they likesmiley

Buying QCTP with set of 5 holders not necessarily a good idea some of the holders are not particularly useful I found. Unless you can get it with 5 standard tool holders.

Tony a chunk of Eco-cast aluminium plate (ground both sides) 600mm x 200mm x 20mm £50 + VAT from Aluminium Warehouse. You do however have to add your own holes, still that's easy with CNCsmiley

How about an aluminium tooling plate? 20 - 25mm thick, drill and tap pattern of fixing holes. Allow to overhang the end of the table by whatever you need. Underside of the overhang could be supported / stiffened by some bolt on beams. Pattern of holes can be what you need and probably as easy to use as T-slots. Think I saw a video of something similar being made on a Tormach for use on that mill.

John, that flip up threader, how does it go on fine threads in Aluminium? Does it benefit from having some counter balance on the back behind the pivot point ?

Thanks for sharing and taking the time to document the process as well. I'm quite hopeless at documenting what I make. I just do it and take the odd picture of setups that were quite involved or innovative for me at the time.

I tried a thread M12 in aluminium, seems to work OK some very fine burrs on the edges of the thread but the tops haven't been rounded at all (I think metric threads should be flat). I ran a bit of green abrasive pad over it and all is good. I put a video on U-Tube, I'll see if it will embed below:-

Warning - The video is 5 minutes long very boring and the auto-focus didn't work very well but it does show how the toolholder works! I haven't got the top-slide on the lathe so I am feeding the tool straight in so not actually the best way to cut the thread. The nut fitted without using a die or chaser which is a result.

To be honest I don't know, I only tested it on a 12mm steel bar with an M12 thread which was fine. I don't think a counterbalance would be a good idea as the tool might then not drop back down cleanly. You could of course manually flip it up at the end of a pass run the lathe back and manually drop the holder back down. You could add a small handle somewhere to make this easier. There are a couple of links at the bottom of the article which show alternative versions with more pictures and even a video. Hope that helps a bit.

The new website looks good and is faster than the old one. Works for me in Firefox and seems OK in Edge.

As someone mentioned, there is a spray can layout blue dye called Dykem that is widely available. Google Dykem layout fluid and you should find it locally.

Really, hmm, I challenge you to find some spray available in the UK

You could try Amazon ***LINK*** £15.65

Thanks Dave, as I said not an original idea of mine but quite an interesting and useful tool. J.S. of this parish has a version that uses one of the chasers out of a Coventry die head instead of an HSS bit.

John

I was mostly writing a web page about making one of these:

It's a flip-up toolholder for screw cutting. Saw it elsewhere on the web and thought I would have a go at my own version. More details ***HERE*** for anyone who would like more info.

Thread: Simple Cad Drawing start-up.....
13/05/2017 09:36:59

Clogs, all the CAD packages have a steep learning curve unfortunately. I currently use Geomagic Design (Alibre) which after a few years I can usually get to do what I want, it's not free though and the price has gone up quite a bit since I bought my copy. I have tried TurboCAD and found it to be unuseable, it doesn't work like any of the "standard" CAD programs. Draftsight is good for 2D and free, FreeCAD is a bit odd in my view.

For full 3D Fusion360 would take some beating. It is free (for hobby use) works on Windows or iMac and there are loads of very good tutorials on the web. It will still take a long time to learn but the results are worthwhile.

There is also Onshape which is browser based and free but I only tried it briefly and found it too dissimilar to what I am used to.

Good Luck with your quest, but remember whatever you choose there is a steep and long learning curve.

Thread: Quick Change Tool Post WM280
11/05/2017 18:08:57

Chris, the WM280 is just a bit bigger 5.5" centre height to the WM250's 5" (280mm swing -v- 250mm swing) as far as I know. Went to check on WARCO's site and it's down for maintenance!

John

11/05/2017 17:09:30

I think you might need the larger model 100 version, check centre heights and maximum tool size etc. I have the model 100 on my WM 250 and your lathe is a bit bigger than mine. Also consider not getting the set, not all the tool holders are useful. Better just to buy the post and a load of standard holders. Ketan might do you a deal!

John

That sounds promising if all you have left is a hole and a flat top to the top-slide, sounds like all you need to do is make a new stud to fit both the top-slide and the tool-post that you choosesmiley

John

11/05/2017 14:05:54

Chris, have a look here to see my version of fitting a QCTP to a WM250 I turned down the boss but there may be other ways of doing it. Some people have just machined the boss off on the mill.

Edit: the stud is pressed in with a roll pin to prevent it turning, it is only a light press fit so can be easity pushed out. There is a picture on the above link (No 26 on the second page) just shows the stud not the getting it out which is in the text.
