Could you use a piece of 4" bright mild steel? If so MaccModels sell rods in lengths of 1", 2" and so on.

Hi Jim,

Your 10V doesn't seem to be machined with much accuracy. I did machine the seatings for the bearings with square bottoms on mine (but I used stock material for the Soleplate, not the Stuart casting). For an engine that is not going to do heavy work brass should do as bearings material, I have used that on several of my models.

Hi Jim,

I built a vertical steam engine based on the Stuart 10 Standard and Cylinder, see here, that you may find useful. Good luck with the rebuild.

Hi Chris,

Some chucks are directly mounted onto the lathe, placing the chuck closer to the spindle bearings. So the chuck will only fit a lathe with the correct type and size of mount. Something like this (from Ajax):

Many chucks needs an adapter plate (backplate). As long as you can find a backplate that fits your lathe you should be able to mount the chuck on your lathe. Discussed here.

Hi Michael,

You could try this link.

Hi Perrie,

Welcome to the forum. Making a new feed-screw is one solution. Have you checked lathes.co.uk? They may have a spare. I assume you have a copy of Know Your Lathe? There is also a Boxford group.

Hi Ian,

When I have installed Oilite bearings they do close up a little when pressed in, just enough to be a running fit. Are the 1" hole reamed to 1"? I assume you have read their Best Machining Practice or Engineering Assist?

Hi Mark,

This has been discussed before, here is one link:

Hi Alan,

There is a Centec site on groups.io, unfortunately the files from Yahoo doesn't seem to have been transferred to the new site. You could ask them for help.

Hi Haydn,

From your photos the half-nut looks worn, especially on the side where there is hardly any thread left.

Hi John,

Welcome to the forum. The FB2 was discussed earlier on this forum, see here, there is also a link to a manual (in German) in that thread.

Hi Steve,

I have fabricated crankshafts by silver soldering (brazing), I make the parts slightly oversize so after brazing I can clean up any distortion. I usually use 1.5mm rod since that is readily available where I live but when I find 1mm rod that is what I buy. Good luck.

Hi Andre,

During the campaign against the Sovjet Union the Germans had access to Manganese in southern Ukraine. They also got Manganese from Hungary and Romania.

My 290 lathe at a bit over 200kg and I would not want to try and get something bigger or heavier across the lawn and into my basement workshop.

Thor

Hi Steven,

Welcome to the forum. Warco sells several different QCTP's, have you asked them? On my 290 lathe I use this QCTP, a friend got a good price many years ago. I have made some extra toolholders.

Looks like the ones used on Bergensbanen in Norway.

Hi Karl,

Welcome to the forum. Carbide tooling needs a rigid lathe, high speed and a certain depth of cut, usually at least the nose rasius of the carbide insert. I often use carbide for the roughing cuts and finish ith a newly honed HSS tool.

Thor

Hi Dennis,

Welcome to the forum. What models do you intend to make?

Thor

Hi Noel,

As far as I know the old ones use M6 (1mm pitch), new ones may use M6 x 0.75 so you should check yours first.
