Burrell Crosshead Guide in Context

I needed to put the Burrell crosshead guide in context. As in bolt it to the cylinder block and check it against the engine overall.

After making the crosshead guide I was nervous that it looked a tad large against the cylinder.

“However, I will reserve judgement until this is put in context with the traction engine. Also, there may be some ways to remove ‘weight’ from the design and essentially make it look slimmer.”

Marking Bolt Locations

marking bolt positions for the crosshead guide

One of the first challenges was marking bolt positions so that this crosshead guide could be fixed to the cylinder.

A fundamental requirement of the bolt locations was they need to work around the steam ports. Also, I needed to ensure I still had room for the cylinder cover bolts.

Essentially this meant bolts had a wider spacing where they located near to the steam port face of the cylinder.

The 8mm carbide slot drill was positioned in the slot it had cut. This gave me a reference surface. Placing the guide on a surface plate and using a square I marked the flange of the guide either side of the 8mm slot drill.

Now I could mark the flange at the centre of the slot. I had a good reference to start.

The 10BA cheesehead brass bolts are not quite correct, but for now these 4 bolts will do.

Note the small centre punch mark on the edge of the flange aligned with the centre of the slot.

When you stand back and put the Burrell crosshead guide into context, it actually looks about right.

The wall thickness could be reduced a bit. This might not be the easiest item to machine now, but worth a go.

  1. Hi Nigel, I’m following your build on hmem. I used your info for a guide on a myfordboy traction engine I’m building. I wanted a opening smokebox door and a few other things not provided for in the plans. Your posts have provided inspiration for some of my build. I might post some pics on hmem. It will give others good laugh. Hopefully I can eventually etch my door like you did yours. For now I’m 7seing the cast wheels I bought with the plans. I also bought the gears from him. There are a bunch of french guys that have a site I correspond with at vapor45. I don’t know if you have seen their site but it has lots of helpful aids. Thheyu also build a bunch of myfordboy traction engines and remade his plans to correct some errors so between them and the originals I might have a running engine in the end. I’m just drilling the holes in the boiled and making a saddle for the engine similar to yours but with a horizontal instead of vertical like yours. I wish you would have posted your instructions a week sooner on how the figure the curvature on the boiler. It was trial and error and a couple of bin parts. But I finally got it. Keep up the postings as alot of us look to you for insperation. Thanks (Smittman) Dave

    • Hi Dave, thanks for the comments. If you want to write an article on the modifications you made to the myfordboy traction engine then we would be more than happy to post on here, a page about the myfordboy traction engine and links to further reading would be great. Must admit that I really wanted the wheels to look like the fullsize ones and hence just had to make them up in parts. I’ve just silver soldered the crankshaft together today and so that will be next and then probably the differential. I bought 0.5mod cutters as I really want to make a working diff.
      Thanks, Nigel
