Shaft diameter is 1/2". The original intention was to drill 29/64, true up with a boring tool and finally ream.

With confirmation that the material is suitable, looks like I will be doing a bit more boring than originally anticipated!

I need to make a pair of bushings for a silver steel crankshaft which will rotate about 4 - 500 rpm.

I've got some bronze - drawn, I believe looking at the spiral marks on it. It's playing hell with the drills, just as bad as phosphor bronze: the hole seeming to close in on the drill and then the inevitable seizure. I could continue by boring, hoping to hit the correct size.

Regardless of technique, if I can machine it successfully will it in fact be good as a bearing material?

Has it jammed because you have wound the cross slide out too far and the lead screw has become disengaged and you can't wind it back in?

If so, you can restore normal operations by trying to wind in the cross slide and at the same time winding the leadscrew handle forwards and backwards maybe half a turn each way. It may well take several attempts, but it will eventually go.

I started off with a Myford S7 and later bought a Harrison M300. S7 is imperial, M300 is metric.

For sure, the M300 is a far more capable turning machine, but I don't like it!

My main dislike on the M300 is the low position of the controls - I seem to be stooping to use the cross slide handwheel. Also being an imperial dinosaur, I struggle with the metric dimensions when moving between the two machines. I don't like the direct reading of the M300 cross slide dial and that doesn't help me.

I have recently sold the M300 and am much more confident in my turning now using the trusty S7.

Harold Hall described collets for square material that would fit inside a standard ER (or probably any other) collet.
I had several Burnerd multisize square collets and I never ever used them!

Seems like it's not too bad living in deepest, darkest West Cork. Skibbereen and Clonakilty are thriving little towns.

Plenty of independent small shops, free parking (2 hour limit) and a very good local market on the weekends. Lidl and Aldi have made an appearance but they do not seem to have taken away too much trade from the smaller independent shops. No Tesco, M & S or other multiples.

Only thing lacking is a decent tool shop!

Here's a 1921 Pop. Mechanics method of clearing a drain. Sounds quite exciting!

The wife of Sussex Steam owner is very seriously ill and the business is moribund at the moment. MiniSteam maybe taking up some of their designs in the future.

Rod. I would be interested in your beam engine kit if Fabiano doesn't want it.

Exactly.

The only possible 'excuse' for English shows and the number of club stands stewarded by club volunteers (well done those people, by the way) and static displays is that 'over there' the exhibitors generally are individuals because Model Engineering clubs as they are in England are very few and far between. Some of the exhibitors to the major shows will travel for several days to get there and back home again afterwards.

One income generating item in Cabin Fever and NAMES are the auctions and commission sales. The last CF that I attended had a lot of non ME but engineering orientated content for auction: There were a lot of antique engineering tools and scientific instruments, including a lot of Tesla items as well as a large number of models. The auction was conducted on the first day and took up most of that day. Items for commission sale were displayed throughout the exhibition with a wanted price label on them. When bought, they were generally removed at the time of sale.

Well, it's 6 days since I messaged Gavin Rex and so far I haven't even had the courtesy of an acknowledgement. Not very encouraging.

I am looking for a similar type of event to Bristol where I can have my own space and run engines if desired. As you say JB, the Midlands show is not like that. Looks like I'm out of luck.

Cost not the problem, Mark. Its the private landing strip that stops me! Ha Ha.

Dave

Thanks for the suggestion, Mark, but they do not accept private entry displays.

I won't be flying with my models!

No doubt by now, most people will know that there will not be a 2019 Bristol ME Exhibition.

I have been going over from Ireland to Bristol for a few years as a private exhibitor and was wondering what other similar exhibitions are around for private exhibitors. Ideally, I would like to attend a show that is on for more than one day to make the travelling worthwhile.

Any suggestions (and perhaps an invitation)? I don't do hot fog.

Tufnol was/is used for many yacht fittings. Self lubricating and long lasting. So another +1 for Tufnol.

If using link belts, remember to install them in the correct orientation, as per pic:

Please send me a Private Message. I'm interested in Brickplayer.

Does anyone remember MiniBrix? Rubber versions of the original Lego pieces and preceded Lego.
Then there was Bako (I think it was called) small steel rods that fitted into a plastic base and thin slabs that slotted between the rods, mostly for house type structures.
