Thread: Boxford Tailstock Accessories
15/04/2020 11:38:45

Paragon Paints do "Boxford Smoke Grey", they advertise on Ebay, a bit pricey but OK for a full paint job. For small accessories, I've mixed Humbrol grey with a bit of blue until it looks near enough.

The less common green that they used is given on Lathes.uk website as BS RAL 6011

fThe Boxford manual is called "Know your lathe". Can be purchased from various on-line outlets. Also, if you search for "Know your Lathe pdf" I'm fairly sure that there's a download out there somewhere.

Hope that helps

Thread: Boxford Toolpost
13/04/2020 12:59:27
Posted by Sam Spoons on 13/04/2020 12:21:21:

This is a shoestring budget project and will probably only get occasional use so I'm leaning towards the four way but the easier adjustability of the QCTP is undeniably attractive (for occasional use ease of setup and operation is important.

If you want cheap, then for years I used toolholders like these on my Boxford. Made from a short length of 1" x 5/8" BMS with a 1/4" slot milled in for the HSS toolbit. The clamp in the photo is actually Myford, but easily made.

I made 15 or so. Not repeatablebut very quick and versatile. For the very heaviest jobs I used a Boxford 4-way, but that wasn't often. ( I've now spent the kids' inheritanceon a QCTP).

Thread: Query on Ajax locomotive and steaming ability

I used to belong to a club which had two members who had built Ajax locos. One was named Ajax the other unnamed, one day the owner of the unnamed one returned to his locomotive to find neatly made nameplates stuck on it - Vim!

Perhaps you need to be of a certain age to get this.

Someone with an abrasive wit.

Thread: Stuart Turner No.9 Slide Valve

Hi Andrew,

Strange no air was escaping if the slide valve was missing. I'd expect a major air-flow from the exhaust. Have you checked the steam passages?

Thread: Parting blades profile.

IIRC, the GHT rear toolpost design did not angle the side of the slot. He instead put a couple of small, (6BA?), skt. hd. grub-screws fairly low down to act as adjustable stops. Could be worth copying.

The other feature was angling the top and bottom edges of the holder slot to match the typical "Eclipse" parting -off blade. This was probably around 4 to 5 deg.

Thread: Inverter Tripping RCD
08/04/2020 14:39:20

For disconnecting the Schneider filters, the caveats in the manual are that to safeguard the VFD the drive switching frequency should not be set above 4kHz and also EMC compliance is not guaranteed.

08/04/2020 13:39:12

I purchased a Schneider VFD for a mill about 6 months ago. Tripped the domestic RCD straight away. Not something i'd experienced with the Teco VFD on my lathe After a brief investigation into type B RCDs, I read the Schneider manual carefully and found a warning about just this problem and its solution. The EMI filters can be disconnected, an internal, removable bridging link is provided for the purpose. Problem solved with no knock-on effects.

Then looked into Teco manual, there is similar provision, which I've not needed to apply. Fingers crossed!

My other VFD, a cheapo Ebay jobbie, gives no trouble. I doubt it has EMI filters.

Thread: 5" gauge tender horns
07/04/2020 19:52:27

Phew! priceof castings seems to rocket.

Could you fabricate from ,say, 1/2" x 1/2" x 1/8" steel angle and silver solder in any necessary triangular webs. A bit fiddly, but cheap.

Alternatively, horns for other designs seem a bit cheaper, eg those for my 5" Priness of Wales are "only" about £65.

Any scope there?

Thread: Which Lathe???

The standard Boxford passes 3/4", (3MT). Bigger bore versions were made but rare.

All are screwcutting except any designated "T" which are very basic.

Model A:- Screwcutting g/box., power cross feed & long. feed

Model B:- Power cross-feed & long. feed

Model C;-Power long. feed.

Myford suffer from the name attracting premium prices. If money is no object Triona list a Connoisseur at the moment. It's said to be in unused condition. Price on Application; no harm in asking, but make sure your pacemaker has a fresh battery!

IIRC I noticed that same Myford a few days ago at £14K. Perhaps it was April 1st.

So, why are the press just showing younger people on the beach, in the park, socialising wherever, What wrong with showing us more mature people, breaking the socialising rules also

I thinkt hey are. The Scottish Sun is showing the Scottish Chief Medical Officer visiting her holiday home, against her own advice. A trip of 100 miles or so. Not for the proles though.

Thread: boiler leak
05/04/2020 08:41:33

Some more detail on the size and design of the boiler would be useful. Perhaps a picture or two.

Apart from your ring suggestion, 2 other possibilities.

1. Copper tube can be expanded in diameter using a drift with a gentle taper.

2. Silver solders are available which form a larger fillet than the lower melting point types. They are less "runny". This could help.

Pickle/clean the new joint areas well.

Thread: Check my sums please

Just asking; does the back face of the wheel have the same runout as the front face. In other words, is the 0.5" wheel thickness consant around the wheel?

1. The belts should slacken when the white knob by the countershaft is pulled forward. Belts should then be moveable. There is a turnbuckle to adjust the belt tension in the tensioned position.

2. Agreed, DO NOT LOCK THE SPINDLE BT MEANS OF THE BACK-GEAR. I have a short piece of 4"x2" wood which I stand on the bed behind the chuck jaws. I grab hold of the drive belt, push sharply away from me and jaw whacks onto the wood. Never failed, but might not be at first go. The further out the jaws are, the better

Thread: 2TB USB drives.

The link given by MichaelG seems unusually candid. These drives have been common on Ebay, at ridiculously low prices, for some time. I've never before noticed one that admits to being fraudulent.

How big is your compressor Ron, could that be the limiting factor?

Looks a very nice engine.

GLR Kennion do 0.115" x 0.5", but 0.062" dia.is going to be difficult I'd imagine.

Look at it this way:-

Statistically, if the last Roman Legionnaire to leave Britain had bought 1 bond just before his departure, then he would have won a prize just about now.

It might have been £1M, ( but more likely £25).
