Nick,

The second drawing is the clue here as Phil P said in the second posting. Thanks, that's a handy diagram to have.

Mark

Thanks Martin!

Barrie,

I got them from Dixi Polytool. Their website is **LINK**

I am in the Netherlands but they probably have a UK shop too.

Mark

You see this is why I hang around here

Excellent info and suggestions, many thanks. I will go the cheapest route first and see how I get along. Dad has a torque wrench so this little attachment will be a good place to start.

Martin, I have seen different torque values for ball bearing nuts, yes. My nuts are plain

Phil, sounds logical. Thanks, that may be the way to do it then.

Jason, I had seen those but was suprised at the price.

John, I am interested in your socket. Do you have a pic? Is it a normal half inch socket modified to fit an ER style nut?

Gents,

After trying the Chinese cheap nasty collets I have ordered a set of Rego-Fix ER25 collets. Beans on toast for a month at least. In order to make them last for as long as possible I would like to use the c correct torque. I didn’t even know there was a torque spec bit there you go.

I was looking at this spanner thingy. Will it work? Seems to my amateur newbie mind to measure torque aroind the wrond axis. I need it measured around the green axis but coupled with a conventional torque wrench it would measure around the red axis wouldn’t it?

Will this work?

Thanks, Mark

Jason, Iain,

That is a 13mm piece of what I thought was silver steel but turned out to be quite soft. I was under the impression that a crankshaft should be made of a hardened and ground material but my newbie status is on full display here, I simply don't know enough about the different metals yet or of their properties to make an educated decision.

I see your point on boring the holes only after getting the material. Almost as if I am going at this bass-ackwards.

Thanks again for the advice Jason and Iain, I will take a look on eBay too.

Mark

Gents,

As the title says, we have reamed the main bearing of our steam engine and we are wondering what material to use for the crankshaft. As we have reamed it 13mm I am assuming we need a precision ground piece for the best fit? And where does one buy a piece?

What would be the best material to use? Tool steel? Silver steel?

Thanks,

Mark

Progress looks good so far Nick, keep 'em coming

Sounds logical, thanks. I thought the seller might have taken them to bits and not been bothered to put them back in order

Thanks again,

Mark

Gents,

I bought some feeler gauges and noticed that they are not in order (see pic). Is this normal and if so, why are they like this? Please excuse the newbie question.

Thanks,

Mark

My Dad and I have made slow but steady progress on the No.1. The main bearings are complete and we have drilled and reamed the holes for the crankshaft. I was a little worried about this operation as it is quite important to get it right and we didn't want to ruin the main bearings.

Anyway, here are some pics. Sorry they are rotated. I have tried and tried but am unable to post them the right way up. I managed a few weeks ago but have forgotten how I did it. Most infuriating.

Excellent I will check that out. Thanks.

Thanks for the speedy replies gents, i share the hobby with my Dad who is 76 so I think I’ll ask Santa to pick one up.

@Geoff, I am based in the Netherlands and have seen them on Hogetex.nl but I just googled and found that Axminster amd Warco sell them too. Also you could try eBay.

Gents,

I have to ask for a Christmas gift and thought of asking for an Optcal Centre Punch. Are these any good? Pros and cons? Any things to look for, brand etc?

Thanks,

Mark

Progress and Failure.

Our engine is progressing steadily but it hasn't been plain sailing. We managed to get the lower bearings into the sole-plate. Just need a skim across the top to make the top surface exactly level.

The upper halves were a different matter. We thought some, pondered a bit and then thought some more and then buggered them up. I have no idea how or where we made the mistake but it all went wrong when we got the 2 halves into the 4 jaw. I have ordered 2 more top halves from Stuart.

Here I am milling to mating surfaces of the top bearing halves to be able to super glue them together.

Failure. The radius is off centre. We could possibly salvage the parts but getting one side correct and placing the incorrectly turned faces on the inside of the engine but that would reduce the crankshaft bearing area so we decided to make 2 new ones.

Brian,

Understood. I’ll give that a try and report back. Thanks,

Mark

Brian, good idea. I was under the impression that the o-ring fit on the inside of the ‘box. The drawing shows otherwise as I see now. Bugger,

I will try your suggestion. I ordered the o-rings anyway so will try and wangle a solution using them.

Thanks again,

Mark

Peter,

No, I am not sure and that is also a possibility, many thanks! As a precaution I have ordered 5 of those rubber 0-rings (BS / USA size 11 which is a 7.65mm ID, a 11.21mm OD and has a material thickness of 1.78mm). I am going to try and seat the washer without removing the 'box

Are you sure that's the correct size, Mike?
