|Thread: Myford 7 Capacity Check|
J A Radford has an elevating head for the Myford in "improvements and accessories for your lathe" TEE Publishing 1998 (from p 57)
It's not a small job, though!
|Thread: sieg mill: normal chuck or collet chuck?|
Kinda depends on whether you want to mill or drill, doesn't it.
Drill chuck is adequate for drilling. Collets for any any all milling - if for no other reason than safety. But you can use a collet chuck to hold drills also, so there's that!
Unless your milling wood ... you can probably do that with a drill chuck in reasonable safety - but I wouldn't.
|Thread: Natural gas for TIG welding|
John you really should consider the helium bagpipe solution i suggested back in early april.
|Thread: A simple indexer|
might be cheaper to just buy a 5c spin indexer and a 5c - er25 adapter
and a 5c - er25 adapter
Although not nearly as much fun
|Thread: Natural gas for TIG welding|
Missing the point - he doesn't want to use Argon ... I get it ... Argon is a PITA - you need to go to the welding supply to buy it, and the bottles are expensive to rent.
A quick peruse of the periodic table of the elements suggests Helium might also be a viable alternative ... you can buy it from your local party supply shop in balloons - you just need to fabricate up an adapter - change out your balloon every few inches of bead, and Bob's your auntie
If you do a lot of welding your could fix up a multi-balloon supply with on old set of bagpipes ... you just need to give the bag a small squeeze every few times you dip your filler
|Thread: 3 Jaw self centering ER chuck|
also worth noting that this setup would allow the easy integration of a depth stop through the back-end of the headstock spindle ... something typically considered an advantage of the 5c over the ER collet.
|Thread: J&S 540 Manual PDF|
well ... since you now have a copy, why don't you upload a link to it so other people can benefit, rather than having to pay the other side of £50 for something which is, essentially, free, from someone who is, in the nicest possible way (because I do value the lathes.co.uk site), a copyright opportunist.
|Thread: Turning Welded steel|
To be fair, JS was mig welding with a known quality of filler wire ... I assume he was choosing a filler wire which would turn, given the face he did this more than occasionally.
|Thread: Breaking drive belts on super mini|
on the topic of parting off ... parting off tools can be very finnicky about being 100% dead on perpendicular ... even a little out and the deeper you go the more you rub on the side. Also, topslide rigidity is a concern in minilathes!
|Thread: Another what is it|
|Notsure if everyone is making a joke or if it is actually an adjustable wrench|
|Thread: Clarke metalworkers 6speed|
much like the above comments - seems expensive unless it's particularly well kitted out. Even then the machine itself is not a particularly great example of far east engineering. For not much more and a little patience on eBay or Gumtree you can get a more recent and well specified Sieg lathe, or something older from Emco.
|Thread: Unknown machinist's vise - info requested|
Those record auto vices come up semi-frequently on ebay in all three sizes (imp, 74, and 75) ... I've bought a few for various tasks through the site.
|Thread: Increasing cost of entry into model engineering|
also ... your timeframe is semi-charmed ... 20 years ago it was almost unknown for a hobbiest to have a milling machine at home ... most milled in a lathe with a vertical workpiece holder ... let alone all the other neat dodads we can buy for not much from ebay (TIG, etc.)
All this stuff I used to salivate over I can now order for mao's tool emporium, and it arrives on my doorstep in a week.
|Thread: Not a model engineer looking for mill advice|
I would say a sieg x2.x would be the best bet ... available from arceurotrade/axminster/chester/warco/ebay/all the usual suspects.
Easy to CNC, good work envelope for people unsure of their use, can be lifted by one person, lotsa mods.
|Thread: proxxon KT70 CNC ?|
If you converted a lathe you would not bother attempting to get the change wheels correct or turn the headstock by hand ... you would just add a 3rd axis to the headstock.
Either way, you will require 3 axis CNC control ... whether it's a lathe with a headstock control or a mill with a rigid 3rd axis is kinda the same destination, just a different path.
You don't mention the size of the spiral turning project, but a dremmel might well be underpowered ... you could consider something a little more powerful ...
There is more info online on converting mills than lathes to CNC, so that might be the path of least resistance ... CNC mills also seem to be a bit more general purpose.
|Thread: Laser/plasma cutting service|
If you already have a air compressor you can pick up a chinese plasma cutter on ebay for £150-ish.
|Thread: What's the best alternative to 'loctited'|
Kinda depends on what the loctite was doing.
If it was locking a thread - then "thread-locked" would seem to be the appropriate past-tense verb - "I use a thread-locking compound to secure my nuts when I don't want them shifting around"
If it was performing a chemical bonding process which is not meant to be reversed - then chemically-bonded - "I was somewhat upset when I inadvertently chemically-bonded my fingers to my little willie (model)
I imagine that Mr Loctite might also have some ideas - perhaps you should ask their brand department ... as brand genericisation is generally considered an undesirable thing for companies with such well known products.
|Thread: Controller for a 3 axis lathe|

|Thread: drill / mill table load|
hehe ... as much as the acroprop is a bit amusing, a small bottle jack with an appropriate length of pipe as a spacer (and a spirit level on the drill table) is a reasonable solution.
I would imagine that 40KG + workpiece + downward pressure is pushing the drill beyond its intended design cone (and I do own one) ... You'll notice that the one on lathes.co.uk mounts the xy table on the base, where this is not a problem.
|Thread: What did you do Today 2018|
I'll grant automatic gearboxes are miles better than they were ... perhaps more efficient than a manual ... but automatic gearboxes can't engine brake ... seems like a compelling safetynet argument for slowing the car down if there is a brake failure ... perhaps going down a steep hill.
