You could always look for Tubal Cain's book on building the S9.

Building the Stuart No.9 Engine That's the book, but wouldn't recommend paying that asking price!

I have a length of 3mm pitch roller chain and need two sprockets of 10 or possibly 12 teeth.

HPC gears list 4mm pitch as their smallest and a search on the internet doesn't reveal any other manufacturer of such a small chain or sprockets.

So over to the brains trust: any ideas on where to get the required sprockets?

The two brackets with set screws in + the angle piece bottom left look like parts from ETW's powered hacksaw machine.

One way is to use a jig for drilling the ports.

For one such jig, have a look at Elmer's Fancy 2 oscillator (wobbler). The drawings can be downloaded from

Download no.18 and the jig is shown in the drawings.

Two sheets? I thought the norm was three: 1 up, 1 down, 1 polish.

Thanks for the suggestions.

I did wonder about using the paper stuck to wood idea, but I will spend the kids inheritance and get a 50 tooth change gear. (The kids don't want the lathe).  I like the idea of the forked detent.

I want to replace the handwheels on my Myford S7 with the GHT design. What is a suitable way to make the 100 divisions on a gear box equipped S7? I don't have a dividing head that fits on the lathe.

I found that my S7 was too low for me to work comfortably. I used 2 pieces of 3" x 2" x !8" hardwood laid front to back and screwed the stand to them.
Killed two birds with one stone: Raised the height sufficiently and the lathe (unbolted to the floor) is perfectly stable.

Welcome, Dave and hello from West Cork.

You might consider joining the Myford Owners .io group to get helpful advice with your machine.

My usual milling machine vice for quite a while has been the very good Warco DH1. About 18 months ago, I bought a Polish Darmet vice that was advertised on eBay. For the larger jobs, I find it excellent.
Just had a look and the 100mm size (which is what I got) is not listed. On their own website it is listed, but the price has gone up considerably.

Have a look at my Myford Lathe album where I have uploaded a drawing for an oil gun adapter that fits the Myford nipples very well - leak free!

It's not my design, by the way. My thanks to the original designer.

I've now read through Mogen Kilde's construction series on his Scroll Saw and I might make one. However, I cannot see fig. 5 nor pictures 22 to 28.

Am I blind, or are there really gaps in the description? I could quite easily work out the eccentric throw, but there maybe others who would need the dimensions.

There must be others who are contemplating constructing this tool, but strangely no-one else has remarked on the missing fig 5.

Isn't there / didn't there used to be a North Cornwall ME society? Also same situation at Liskeard.
Many years since I lived in the area so haven't got any contact details.

EKP Supplies are at Barnstaple. They may be able to help you.

Very nice model. It would be worth changing the plastic plaited rope for hemp 3 strand rope for added authenticity.

My automatic car has 3 letters on the gear selector in addition to P: D,N,R.

I had to be told that they didn't stand for Day, Night and Race.

I've just downloaded from your link and tried it out. Seems to work OK for me on Windoz 7 Pro.

From what I saw when visiting the US shows, there was a very good attendance.

One major difference is that there are very few club stands, most exhibitors had their own stand and the great advantage is that any visitor with a question could ask the builder directly, unlike a club stand where the steward probably knows nothing about most of the models on display. There is much more emphasis over there on internal combustion engines and hot air engines rather than steam. There was also an auction sale on site with tools, models, materials an even antique machinery.

When I visited GEARS over in Portland OR, the ladies of the exhibitors were not left out on a limb looking disinterestedly at the engines while hubby was rapt: they had their own display (in the same building) of their crafts, mostly quilting and needlework sort of things. It was very noticeable how many of the men went and viewed them.

Do you want the die filer as a working tool or as a machining exercise?

If a working tool, bearing in mind the size of your lathe, and the future projects you may make with it, have you considered a bar stock version? There are at least two die filers on homemadetools. The first of the two following links is very simple and would get you going pdq. The second looks to be a bit more 'workmanlike' and closer to a machine made from castings and maybe more to your liking.

I know you like the look of castings. The problem may be that if you butcher one of the Martin Model castings, especially them coming over the water from USA, it could be an expensive mistake.

Dave

Have you thought of building an engine using bar stock materials? If you have no or little experience, a simple bar stock engine will give you something to help you get used to working with your new lathe.

It would work out considerably cheaper than a casting kit and if/when you make a mistake, a new bit of steel/ally would be easier, and again cheaper than getting a replacement casting.

John-Tom is a good place to have a look at ideas. http://www.john-tom.com/html/SteamPlans.html

I started off with an Emco FB2. Super machine for smaller work. An acquaintance wanted to buy it off me, so off it went and the proceeds went to 'upgrade' to a Wabeco F1410. The less said about it, the better.

Also had a Thiel 158, ex Armstrong Whitworth Aircraft Co. from 1971. Just about every attachment came with it. Again a super machine, but me being of a senior age I sold it while I had a buyer, along with my Harrison M300. Manual metal machine users are very few and far between in Ireland, and it was a stage in downsizing the workshop.
