Myfordboys site gives size of motor etc, works well on mine, but I think you will find limit switches are a good idea, you can get more than a gentle hum if you reach too far.

Have a look at Myfordboys website for fitting stepper motors to your mill, not using arduino for control, but works well for feeding fast and slow feeds. Some pics on my albums of the stepper fitted to my mill, no gearing needed.

The pillar is a heavy lump to turn down, and quite a lot of heat is needed to silver solder the cylinder casting together.

Quite a nice engine to make though. I have some pics on my album of it nearly finished.

I would have posted a video of the finished engine running on air if I knew how.

Just to make my earlier post clearer, the table is locked with the nut and bolt arrangement, no inserts, whilst the head uses the arrangement shown above with the internal clamps.

The support collar fitted under the head to support it whilst moving is also a nut and bolt arrangement.

My table locks with the handle shown in Ian Parkins post without any undue force.

Just had a look at my Star, and the table is clamped by a bolt straight through to the locking handle, no collars.

The split is not the whole length of the collar.

The head casting is locked via two clamps pulling on to the column.

Might be a sign of the times, but it will not get better for exhibitors such as Warco when they spend time talking to old mates instead of bothering with customers wanting to spend money with them.

Too many retailers have thought that the customer will always be there to wait for them, today the world has changed as many have found when the customer has gone to someone who will pay attention to them and provide good service.

I spent my money a couple of stalls down, who had the time for me, and goods that I wanted.

Guess who now gets first chance when I am in the market?

Rocket moved in 2018 to Newcastle, then to Manchester, and will be going to National Railway Museum in York later this year.

2nd from the right looks like a valve seat refacer for car cylinder er heads, screws on to a mandrel and cuts the face of the valve seat. Usually come in sets with different angles for inlet and exhaust valves.

Still have a set hiding out from when I used to play about with BMC a & b heads.

Spent hours polishing the ports etc to a shine, but saw the other day from a respected head tuner that the best results came from leaving the finish as ground, as it gave better mixing of the petrol air mix.

Wish I had known that 50 years ago😩.

Just beat me to it Phil, any installation is only as good as the person who installed it.

That has worked for me for many years👍

Ditto for the feet on my 254s, good fitment, reccomend.

Use a set of cheap diamond burrs bought years ago for all sorts of materials, never had any problems with them, just give them a try.

Saved me many an hour on odd shaped castings etc that need cleaning up.

True!

Fitted spacers similar to Duncan when I changed my ml7 to my 254s, work fine.

Wouldn’t want to get those cables caught up in it Terry, nice as it is lol.

More cnc wouldn’t tempt me back to MEW, that was one of the reasons I cancelled my subscription in the first place. Long lines of g code as Blowlamps above leave me cold.

Each to there own though.

Don’t forget Markham Grange steam museum and garden center just up the road also, many engines with some in steam.

Leeds, country’s third biggest city half an hour away for swmbo to empty your wallet, plus Armley industrial museum.

Coast and the Dales nearby, in “gods own county”, centrally placed in UK so easier access than the Sandown show, went to Sandown a few years ago and was disappointed.

Stainless steel balls are available on the net, use them for governor balls, drill ok without heating.

Could you use an epoxy adhesive, devcon etc , I believe some radiators are now glued together rather than soldered?

possibly adding some brass rivets for extra security, invisible if countersunk.

Ok on iPad using Safari.
