Thank you all for your thoughts and advice. will start first with some air and see what happens

Thanks for the advice. So you are saying its fine for the stays to be screwed.

I'll have to try pressure test. Will have to play with how much torque to give them.Though internal pressure will i expect tighten against them. Under heat they will expand in length regardless of if soldered or not. Also seem to see many that do have soldered stays. But if this works like it is thats fine.

The stay is only screwed one end and long 'bolt' with head and other end (see images), copper washers underneath at each end. So basically they have a flat nut threaded internally one end, and 'bolt' head the other end.

cheers

I recently acquired what is in many respects quite a well built horizontal 'marine' type boiler. It has the normal centre flue and cross tubes. It looks to be almost finished but unused.

Everything is silver soldered except for the two longitudinal stays which have copper washers under bronze fittings each end. At one end of the stays the bronze fitting has spanner flats and of course can be unscrewed. All of this has been in place for a long time and sat on a shelf by the look of it.

I would have thought the stays would seal better if silver soldered?

Though I see a few articles about comsol? or even using loctite on threaded stays to caulk/seal.

Any recommendations on how to seal these, or should I silver solder them? of should give it a good pickle and loctite I leave them?

Cheers

thanks Jason, will look them up.

cheers

there also looks to be a similar series? 'Stationary steam engine makers' by george watkins is that the same or another series?

Hi,

Just interested in asking which volumes of the 'Stationary steam engines of great Britain' by Watkins series by Watkins would be recommended for beam engines, or any volumes recommended in general. Or are they all equally good?

Cheers

trove is a great resource and great for finding advertisements for machinery, tools bikes, household or whatever it may be.

Sure they will keep adding to the digital library and keep digitising - though continual budget cuts never help.

Cheers

Thanks, Hopper, Roderick and Alan, that's great.

yes it is the Model Engineering - a guide to model workshop practice .

Didn't have much luck with google books, but Alan's link (thanks Alan) is actually to the 1919 reprint so is quite close to mine and has the same number of pages and cant see much difference and appears almost identical but must be some minor edits. Otherwise I sure it will be just fine.

Cheers.

HI All,

I was lucky enough to acquire a few old engineering texts and catalogues a while back. One of them was a 1920 reprint of the Henry Greenly Model engineering book. Very interesting book, covers a lot of subjects not all in great detail but is combined with dimensioned drawings that help out.

only problem is its missing part of the index. Would anyone know where I might find a copy of a complete index, without buying another copy of the book?

thanks

try turning the diameter down slightly more than you have

Think I have some old gramaphone parts with worms on like that.

not sure how you would use the rear tool post support without having to reset it and the tool for each cut, as the tool post would move if you moved the cross slide.

tailstock support, travelling steady set well, and fine cuts...

Hi Matt,

I had a reply from them back in late July. I didn't follow through with an order at the time though, however I was advised that they did have a lot of emails and had initially missed my inquiry. Not sure what the situation is there now though.

keep it simple and do it as Bazyle suggested. That basically how I did my last one - with the side of an end mill but in a dividing head.

does look interesting, always good to get the tap out without damaging the thread/hole

you do see many people on youtube videos drilling and reaming to size, but as said, you are best drilling under size then boring

Thanks, thought that it was outdated being 2019 still, but had a look in the Clarkson. Seems a bit of a basic web site, with most things in the catalogue.

there's alot of pages - too bad you can't search, but should be good browsing.

cheers

Had been looking for a beam engine project and had seen the Sanderson Beam engines. Thought they looked nice with the design and arrangement of the column.

Does anyone still produce those as kits? Seem to be the odd one come up for sale every now and then or had been for sale on station road steam but cant find current kits?

thanks

thanks,

looks like I will either need to make some or maybe fit one of my other spare chucks.

I have quite a nice Victoria universal dividing head that I have had for a little while. Its the smaller one and came with tailstock and extra dividing plate. It also has a Victoria 3 jaw chuck, its 4-1/4" diameter chuck .

As I have other options for dividing and simple indexing, i have not had cause to use it for now. The victoria DH did not come with any outside jaws for the Victoria chuck. I can envisage a time where I will need to use it but need different jaws.

Any ideas where I could find some jaws for it, or what may be compatible?

Hi Bill,

Big thanks, files have come through and is exactly what I was looking for.

I also tried to set up an album. I was able to identify one more part (screw thread) that was in the box among the random bits. hope the image works this time.

Looks like I have the main parts needed. I can find the random grub screws and bolts. The screw has a little rust so will clean it up and see if I am happy with it. I might also fit a graduated dial.

Think those parts have been sitting the box for abut 50 years.
