Thread: What did you do today (2015)
22/07/2015 23:02:15
the two images are in the wrong order to allow the simple cross-eye'd mechanism to work - produce a new image with the current rh image transposed to the lha and it becomes very effective.
Thread: Which chuck to buy for first lathe ?
15/07/2015 21:55:00
Steven - yes but no such lever on my Warco WM180 which is made by them (possibly adapted to Warco's spec) - I note by review of WM250V in #231 MEW that it has such a mechanism - reversing chuck rotation is no use unless you can also reverse leadscrew - if leadscrew was also easily unlocked from chuck rotation then an external motor and or handle could be added

"Here is another brand I had not heard of before : Real Bull." - sold in UK under Warco badging - one 'gotcha" is that the lead screw cannot be disengaged nor direction changed wrt chuck - hence the cover needed for some models which apparently leads to possible problems as only 1 half nut but more importantly can't it seems do LH threads
Thread: What compressor
10/07/2015 20:10:01
David - interested in your soundproofing - I have one of the cheap Screwfix models but not sure how you can soundproof without running into overheating problems
09/07/2015 21:13:41
Screwfix have a special offer on a 12l compressor 180lt/min (abt 6cfm max 10bar for a penny under ?60 - reasonable size (fits in an 18" cube but 1.5kw + like all compressors it seem quite noisy - comparable to the 95dBa of my woodworking dust extractor) Axminster sell a supposedly very quiet model but at 6x the price
Thread: NG10 blow gun Thread- any idea?
06/07/2015 21:27:04
you may have determined thread by now but my cheapo Toolstation air blow gun with 'long reach' uses the same thread between body and long reach extension tube that my old Miller compressor has, thus would appear to be 1/8 BSP - found Axminster to a converter to 1/4 BSP for little more than the cost of the brass I planned to make one with

the American NPT 1/8 is 27 tpi tho with same pipe OD - now I'm worried as not sure I could easily note the difference over the small length of thread available - does anyone own one of these old compressors? - being British made I assume would be BS
05/07/2015 22:18:40
is it BSPP 1/8th - found the same on a Miller 2000 small compressor intended for air brush use OD of male is 10.3 mm with 28 TPI - I now need to make a converter to 1/4 BSP

maybe some one could explain these strange pipe sizing threads ?

thanks Russell applied fair amount of heat from a pre war 150W soldering iron then hit hard with a small chisel + hammer around the join of base + hex bar and worked it free - now to make a better version with ball races

mill.jpg

Finally added my X-axis DRO to my small X1 Mill - not quite as planned as having fought the gibs on replacing the table after fixing the brackets didn't fancy repeating it once I'd measured up the position for fixing the head.

I intend to add a small strip of plexiglass flush with table top (allowed for in bracket positions) but needed to restore my old bandsaw which has a low speed ideal for plastics (my woodworking table saw tends to melt some plastics) - wanted to replace or improve the old guides but cannot separate the guide body from the hex bar

bsaw.jpg

the body is I think cast - nominally held by a grub screw at back (removed) - any suggestions as to best method to separate them without destroying the body

Calling in to B+Q to buy some Ali Angle (10% off for us oldies) I was tempted by a Record 100mm vice which had removable jaws - well they were after a far amount of effort having it seemed been locktited into place using 1/4in 20tpi 12mm screws with 10mm pan heads reset into jaws (I'd fondly imagined all would be metric by now).

Since I wanted some mild steel plain jaws and my stock was slightly thinner than the original jaws I needed to remove the junk in the thread but found my 1/4 UNC bottoming tap had such a long unthreaded point as to not reach deep enough - a much older 1/4 BSW tap was however threaded to within 2 threads of the end and also had a 1/8th counterbore at end - anyway this removed sufficient gunk (not metal) to allow the screws to enter 3 or 4 mm further in.

My real surprise was that the UNC tap was pretty useless for bottoming in a blind hole - is this common with such taps and is it easy to face the end on the lathe to remove much of the point?
Thread: Case hardening mild steel
24/06/2015 20:27:20
I took one of these generic filters apart(can't recall brand name) - seems more sand than charcoal in the one I chose though might explain why it clogs up fairly quickly - hard taps with a spoon gets flow working again.
Thread: Good quality flooring for indoor workshop
21/06/2015 21:52:03
maybe professional kitchen suppliers - I used Nisbets in past for such equipment (knives, pans, icecream makers etc) and found then fine with good quality products eg http://www.nisbets.co.uk/Coba-Kitchen-Mat-850-x-750mm/F293/ProductDetail.raction
is one of their grease, oil proof kitchen mats tho I've not used this myself I doubt that carpeting is suitable for any metal bashing workshop - my own small workshop is my cellar using wooden suspended flooring over concrete base - for many years purely woodwork for which some carpet offcuts could be used for mats but need frequent vacuuming to remove dust etc but having now, post death of a friend who did any metal work for me, I find that even drilling metal spreads swarf far and wide and carpets act as magnets for it - lino + rubber mats would I think be better

Ed
is the QCTP fitted to a WM180 ? - if so any problems (it looks rather like the ArcEuro supplied Piston) - even as an absolute beginner on the lathe the 4way post is already my least favourite item

Thread: swarf!
20/06/2015 17:19:20
buy a cheap pair of safety shoes (eg from Screwfix, Wickes etc who often have them at low prices) and leave then just inside the workshop door with a mat at door (green is very good for showing up metal to wipe shoes on) + like all good Japanese change your shoes as you enter the sanctum of the workshop (if clogs were still available at sensible price I'd suggest these)
Thread: Soft end MT mandrels - soft att the way through ?
18/06/2015 16:50:28
there is a comment in latest MEW #230 page 9 re softening an ARC supplied taper by baking for 30min at full temp [unspecified ?250 deg C] in oven

depends on where you downloaded from - many at one time reputable sites seem to have been taken over by certain USA based companies (eg Sourceforge) who now happily scam the unwary by packaging unwanted 'help' bars etc with the wanted software (usually in the slightly more reputable ones there is a well hidden box to just download the single program you want to meet their legal requirements to the software creator) - as for Yahoo well it's just one level above scammer - my own suggestion is that if the software worked on XP then you have a good chance of it working under Wine on Linux (eg Mint, Debian tho be wary of Ubuntu as Canonical now default to spyware included tho this is easily turned off) and the repository for Debian is free of such scamming techniques

Thread: Pop up ad on home page
16/06/2015 23:22:47
I'm surprised that it was seen - on Firefox (well certainly on Linux can't speak for other walled gardened O/S's) they are blocked by default - also there are several useful extensions eg No Script, Adblocker + request policy (blocks material from sites other than original web page - eg most of the trackers etc) make web browsing much less of a gamble as to what malware you may pick up (one believable statistic is that some 40% of Windoze machines are infected with malware or similar)
15/06/2015 22:20:35
no pop up here - firefox + noscript works wonders - I usually browse with images switched off as avoids various tracking schemes as well as saving bandwidth

Thread: Safety glasses for spectacle wearers.
14/06/2015 17:06:17
I wear a plastic safety 'overspecs' whilst milling etc - similar ones are GBP 1.39 from screwfix
you can get specialist safety glasses (material + how much surround safety depends somewhat on the style + 'glass' provided (I have a brother who is an optician - just try a smaller opticians with info as to just what you are trying to protect from though these are quite expensive.
