Thread: 1/4" BSF v 1/4" CEI
04/02/2020 05:26:11

No, the OP is correct, many, especially BSA/Triumph used fine threads for 1/4" fasteners holding covers onto the alloy c/cases, Triumph used BSW originally, then in the 60's went CEI, and finally back to the better UNC in 1969.

Originally these were CEI, and plenty of m/c specialist shops will sell you a pack for all 3 covers or just a pack for timing cover, primary cover, or gearbox cover.

Choice of BZP, Chrome or S/Steel, the choice is yours on how much you want to spend.

Then there are shops like Custom Fasteners...

Thread: What bench drill
04/02/2020 05:17:54

It sounds as though the cheap Asian drill may have become cheaper over time: a friend gave me an old Astra import which had been condemned by his employers on account of the flange connecting the column to the base having cracked in service; this was easily replaced and, despite being rather noisy, it has given good service for some years. Checking the quill at full extension just now revealed no obvious side play.

The main limitation of these machines for me is the overhead in time of setting the speed; there seem to be rather few drills available with rapid speed change.

+1. My Taiwanese bench drill (2MT, 16mm chuck, 3 pulleys 12 speed) was purchased new in 1982.

Drilled 1000's of holes inc a lot of big stuff like 19mm holes, used commercially in my UK pro workshop for 15 years, and is STILL GOING STRONG.

No slop in the quill, original bearings, original motor, changed the belts once.

Grown rather fond of the thing.

AJS, Mash, Sinnis, Tiger, GPX, and at least a dozen others, all badge engineered made in China.

Some specify their own components, some fit higher end components like chains, shocks and tyres their end once received from the containers on the docks.

Not knocking them, just saying.

The Guardian story does show what a bunch of sharks were running the new Norton show, using the historic name to milk money out of government development programs and pensioners' savings.

Norton has folded more often than a Moulton pedal cycle. The firm's owners since Manganese Bronze, the last 40 years, have generally been dodgy to say the least. The one who owned the company when it was at Shenstone, when it built and raced rotaries, was done for fraud.

All the old British motorcycle company names have a high value and most, A.J.S., Enfield and Triumph excepted since they are in the motorcycle business, attract fraudsters, hucksters and chancers.

The British motorcycle industry in its glory days was something of an illusion. The investment was low, for a few years the shareholders did well and the directors, generally, were rubbish. In the 1950s Lord Docker ran BSA which made BSA, Triumph, Ariel and Sunbeam motorcycles - enough said.

And I own 4 British bikes.

JA

Er, AJS is Chinese and makes 125 and 230cc albeit pretty, small retro style motorcycles for the learner market.

Somebody mentioned Brough made in France, well yes, but it is a top dollar, or should that be top Euro motorcycle, modern, unique, and plenty of styling cues to it's forefathers with some fantastic engineering, starting prices at 49k GBP, and a waiting list for the latest ones.

Well I think an apology is in order. I sharpened a tool and honed it with a diamond block, I also adjusted the feed to as fine as was possible, The machine then cut a 2mm cut using some neat cutting oil. The finish was brilliant. So we can all learn from this excellent forum.

No apology needed. We all can learn, inc me. The above book is highly recommended.

Re a nice DOC on a shaper - great fun. Innit.

As per usual, some of the reporting is downright outrageously bad. Inc the BBC and the Guardian.

Norton famous for being in a Che Guavara film and the James Bond movie Spectre?

Really?

Howzabout all the engineering feats? The TT wins? The Featherbed frame? The Commando chassis? The Wankel rotary bike winning at the TT again?

Oh and then the previous ownerships, the original failed companies, etc, i could go on.

Jeez.

Norton, a crap business model this century, but a wonderful brand.

Oh and they made some wonderful motorcycles in the past, RIP.

Well just to check I set a 2" square by 6" long piece of BMS up today. Selected the lowest pulley speed. VSD at 50Hz and had a go with a 2mm DOC. As soon as the cutting tool got to its full 2mm cut the machine stalled ? God knows what an 3mm DOC would have achieved. I would be interested to see how your cutting tool was ground. I may not have the correct tool shape. More than willing to have another go with a different cutting tool.

As Ian above concurs, on smaller machines like our Boxford 8"ers, a big DOC recquires a fine feed.

Re tool grinds, i've got most of mine from the best shaper book out there, still available to download and print for free off the net, all 320 odd pages of it, "Suggested Unit Course In Shaper Work" by Delmar Publishers Inc, USA.

Pretty basic shapes, all the common 5-15 degree angles, err on the lesser angles and make sure the tool is honed (or ground on a T&CG) to RAZOR SHARPNESS.

I would stay clear of those Asian cross vise, X-Y tables, you want precise movement in all planes with no shake or wobble.

You want a very fine in feed, an absolute maximum of a thou, and a very coarse cross feed wiping across the wheel, why some T&CG's have a handle rather than a wheel.

I agree with Clive's points above as a starting point.

I to have a Boxford 8" shaping machine and Tom Senior milling machine, I usually use the shaping machine to reduce bar stock to the correct usable size. It gives a fabulous finish and is very enjoyable to use, It will remove 0.5mm cuts on BMS with ease, although I saw somebody on here a while ago stating his could cut 2.0mm cuts on BMS,,,,,,not hope in hell.

When I was an apprentice at ICI Billingham many years ago I watched a large Shaping machine in the mill wrights shop throw huge red hot cuttings all over the workshop. Happy days.

Sigh.

I presume you meant me. Again. Here's some proof. Boxford 8" with a 3/4hp motor, single phase. Even the owners manual states it will rip 3mm DOC off.

My suggestion is don't baby the machine or learn some proper tool grinds.

The above were 1.5mm cuts minimum (0.060", maybe 2mm (0.80", can't remember, but the steel was nasty flame cut no-name. Stroke was the full 8" and slowest speed with a light feed.

Note the flame/oxy cut billet below.

Same stuff finished off with a shear tool. Notice the difference in swarf with pic no. 1 above.

+1 on "most" of the comments above.

A mill even with a fly cutter can never replicate the finish a shaper can achieve with the right ground tool, especially a shear tool taking a final couple of thou off.

Internal keyways and gear cutting are also a boon with the shaper.

It may often be slower vs a mill on certain procedures, but it is a helluva lot more fun.

I get immense enjoyment from operating the lathe and the shaper, but a mill is always a "do i have to?", "i suppose i must", type job, i find a lot of common, simple milling operations almost boring. The lathe and shaper - never.

I note there are a lot of Tom Senior mill and Boxford shaper owners above, great minds think alike, perhaps we should start a society/club?

Hi Steve, Moore and Wright used to be a good name for measuring equipment 20 ish years ago. The stuff I have seen in the last few years at customers' in industry under that brand name was cheaply made badly finished far eastern rubbish. Same for Fowler and even some items from Starrett. I think firms there have bought the rights to use these old and trusted brand names and are badging their tat with the names to gain market trust.

I personally prefer Mitutoyo and have many of their older instruments, beautifully made and finished, that continue to be accurate and operate beautifully, earning their keep. Absolutely happy with those, some I have used for 35 years.

Several here though have reported there are fake Mitutoyo instruments being sold.

One 0-8" dial caliper I ordered recently was extremely roughly finished, full of gritty muck, and would not operate smoothly. It was genuine Mitutoyo, very expensive, but marked as made in Brazil (apparently by semi skilled staff not following the normal high Mitutoyo standards). I sent it back, but had to pay a 15% restocking fee to the dealer.

My recommendation would still be to buy Mitutoyo but only from a genuine Mitutoyo distributor near you, and if you are not 100 % satisfied with what you buy, send it back.

Bad measuring instruments can really steal the satisfaction and enjoyment of making things. I hope you can find some good ones and leave the tat behind.

Edited By Jeff Dayman on 23/01/2020 20:02:08

A couple of points;

First paragraph - other way round, Established Western brands inc Starrett have a cheaper line where stuff is made in the "Far East". They are the ones gladly outsourcing to Chinese factories.

Shareholders love it, the end user not so much.

You can buy a Starrett dial caliper for $40 or $300, the choice is yours.

Re, Mitutoyo made in Brazil. A Mit factory making the same Mit item with THE SAME PART NO. for worldwide sale should have the same quality. There is no such thing as "semi skilled staff not following normal Mit high stds". It does'nt happen, and Mitutoyo would not let it happen.

You either got a dud (rare) or a fake (common).

Get a Mitutoyo, excellent verniers and the battery lasts for years

Whats a battery?

A measuring instrument with a battery?

Where have i been these last decades?

For easy peasy quick 'n cheeful i use dial calipers.

For precision, the vernier calipers

for proper precision, the mics.

No batteries were harmed in this post.

Works well for tramming in a vise also. use one all the time.

Use mine for tramming the mill and shaper vises in.

TBH in the workshop you want one of each type.

Re the OP, for a NOS Compac, that looks like decent money.

Thread: A tales of two lathes

Those Kerry's are very nice lathes, IMO a better lathe than a Viceroy which is basically a posh Boxford.

As others have said, comes down to equipment, accessories and condition.

All things being equal, the Kerry every time.

a proud Boxford VSL owner.

I'd wait the couple of days and put the proper stuff you ordered and paid for.
