Absolutely, a beautiful piece of kit!!

Bill

My experience is similar to Buffer. I was a Draftsman at the Admiralty in the mid 70s. The task involved calculating the volume of spaces on a ship. The one that I was loaned from the store, was an English one (maybe Moore and Wright, but I 'm not sure), first purchased and calibrated on 1936. There were several inspection stamps suggesting that is was looked at every five to ten years. The instructions were excellent, however because the task involved lots of repetition calculations, I ended up not using the planimeter.

No doubt its in a Museum now, complete with my notes!!

I thought about suggesting that the risers be at least tempered to ensure that they were not in cast condition (T0) Then it occurred to me that the rider obviously never falls off as he doesn't appear to use gloves, so the risers will never be stressed in an emergency situation.

If this was for my motorcycle I would have used a high grade bar or plate material, 2024 T4 or 7075 T651. The machining would have been more challenging but not too difficult.

Nice bike and a nice project though. Best of luck

Luxury!! I'm still waiting for 318.

cheers I think

Bill

I've just tried to access the digital issues using my latest edition 318 which arrived yesterday. I've tried every concoction of a 5 and 6 digit on the carrier sheets with no success. I'm beginning to feel paranoid about it. Not impressed so far, maybe I need a funny handshake, or sacrifice something valuable.

Cheers, in an off hand sort of way

Bill

I've pretty much given up. I haven't seen a magazine since 316 arrived some time ago, I've not been able to see the digital copy for months, so really I'm just waiting for my (print and digital) subscriptions to lapse in April 2023, then I really will, just give up!!

In the 60s, Dad was a commercial traveler and he considered himself as a "professional" driver. At one time he did a course run by the Police about safety driving. One thing he was told that was heard by the instructor which may upset someone, "....there's NO such thing as an accident, they are all the fault of somebody"

Even though I haven't ridden a motorcycle for about twenty five years, I still look on myself as a motorcyclist, i.e. trying to survive with tailgaters, trying to work out what drivers are doing when they don't believe in signalling etc etc. I had an MGBGT for about 11 years and it was good fun, especially on a smooth bendy road, I looked on it as if it was a motorcycle with 4 wheels. Yes I thoroughly enjoyed that!! When I had a knee replacement the routine maintenance mean't that it had to go. Its replacement was a Subaru Impreza, normally aspirated with a 5 speed manual gearbox. Superb, great to drive, reliable, handled and steered beautifully. It was replaced after 11 years, it was chopped in for the latest version, subtlely different, had a 6 speed manual gearbox and the cam drive is a chain rather that the silly cam belts. I still enjoy driving it, even the boss likes it. Even though the next "Big One" at 75 is approaching shortly I still enjoy driving!!

When I had to work for a living I was making some workshop instructions. One of the points that can remember was the depth of the holes which can be reliably performed without too much care.....this was three times the diameter. In the case of a 3.3mm diameter hole, a reliable hole depth could be 9.9mm. Obviously this is a worst case, as mentioned, pecking is a cure as is cleaning the drill, using a sharp good quality drill etc etc

When I worked in a shipyard, the chippies used to use a scribing tool to match wooden wainscotting panels to a steel, frequently cambered deck. They were then cut by a handsaw with a ten or so degree angle so that the wainscoting finished at a good match. Obviously what everyone has previously said, but most of the chippies didn't have a special specific tool as described they used a small appropriate piece of scrap wood and a pencil.

Nothing new, just good tradesmen!!

cheers

Bill

I'm on the verge of giving up. Despite my subscription showing that it's current, I have not received any issues for a while, cannot see any digital issues. The forum seems to be in most "Myford" threads....time served, dust coated, pipe smoking old scrapers all saying the times at 1910 were perfect. I keep hoping that the magazine it will get better, but realistically it probably won't.

best wishes ....hopefuly

Yes I'm sorry I mentioned my metal toolboxes in a wooden toolbox thread, but it occurred to me that someone might be sparked by something............

cheers

Bill

In the 60s when I had some waiting time, I used my idle time making toolboxes, nothing complex and made out of metal...al alloy. The end panels were csk. riveted into place, and there was a option of a tool tray. My girlfriend's Father was the paint shop foreman, so I could get toolboxes painted "...whatever was in the spray gun". In the high point I made seven or eight in a day. From memory they were about five bob a pop. I had a few one of them was all the tooling to make them, folding tools, piano hinges (not hardware hinges but special ones) riveting sets etc

There's probably an opportunity there for someone........

White metal bearings were involved a long time ago when decent ball or taper bearings hadn't been invited. The shells used for the use of engines (car, motorbike etc) require a VERY accurate and ground journal, they should not be scraped "in", they simply require that they are fit in the correct recess and have some appropriate oil. I think that Tony Vandervells concern invited them in the 50s.

Most good quality machine tools these days involve ball, roller or taper bearings, some involve ceramic balls, these are capable of very high r.p.m They can be eye watering cost, because the Careful Concern Company will use laboratory type clean room to achieve the cleanliness involved. Probably not a clean room were they could process surgery, or make electronics, but very very clean nonetheless.

It was my task to scrape in a 10" split front bearing, and a 8" back split bearing, from memory it took over a week, too get it fitted. But then it was VERY slow, maybe 100 r.p.m.

Which by the way is why "Fitters" are called "Fitters", because the make precision things"Fitted", not just use a new part in a cardboard box.

cheers

Bill

I mean't to add.....don't use cheap/soft al.alloy. Use only the harder grades like 6061, 6082, 2024, 2014, 7075 everything at T6 or better. The soft alloys, like those bought in a hardware shop are rubbish, it's just a waste of time.

cheers

I may as well contribute, I don't like using WD40 except for removing water , so I use kerosene (paraffin) and a really sharp cutter, polished if possible, and run it at as fast as I can on my little Sieg X2 , a max of about 3,000 rpm. I know a lot of people like WD40, but I found it leaves a waxy deposit all over everything. Some people may like that I suppose.

cheers

Bill

Glad to hear. From memory LMS do toolholder sizes by 1/4" x 1/4" and 3/8" x 3/8" , and 1/2" x 1/2" sizes, I got 3/8" sizes and they are very handy. I also got a couple of sizes for the credit card diamond thing, they can make the top of the insert REALLY good finish!!

Best of luck!!

cheers

I would look for someone who builds aircraft. But I live in Australia. But either 7075 T651 or 2024 T3 should be available in the UK, but Amazon or eBay are likely to be not a lot of use.

cheers

Bill

LMS is "Little Machine Shop"

I have used A.R.Warners sets (tool holder and inserts) for 20 odd years. It seems like they can be offered by Glanze, They are first class. The insert can use a credit card diamond thing and makes the insert brand new and really sharp. They are expensive, but they are worth it. Obviously people will complain about the insert don't have any complex grinding, put they are really worth it even though they are so easy.

cheers

Epoxy glass material has been used for PCBs (printed circuit boards) and are used in a few thickness's. It can be cut but not really accurate.

Any of the SRBP/SRPL (synthetic resin bonded paper, and synthetic resin bonded linen, if I remember rightly the SRPL has better properties) machine moderately well. Look at Tufnol, they make it, they market it in all sorts of special trade names (Carp, Whale etc)

Acetal resin could be quite interesting. The sheet panels are probably not adequately flat for your purpose, so they would need to be machined. It can be a challenge.

Personally I would suggest that you use 7075 T651, its very strong, i.e. better than steel, machines beautifully, relatively cheap. Probably to easy.

cheers
