Oh Dear - 2 phases down it is not going to even move

I used a V shaped wood router bit. They have tungsten carbide cutting blades.Did the job

Again thank you for all your replies

It apears to me most if not all are made in China and that the quality and price depends on the retailer, his margins, and what the customer will accept and be willing to pay.

Thank you for your replies.

Done that

Hi

Has anyone have any up to date opinions on multifix tool posts and their clones.

I use a four post tool holder normaly. I also have a Dickson tool post but on some of the holders clamping is poor and the cam can go over centre. Some do not hold the centre height between tool changes.

Buy cheap buy twice!

Any advice is welcome.

Our house is aprox 250 years old, here long before any one living was born.

No number,no problems with deliveries

Common sense of the people delivering sorts it all out.

It may not be the settings I once had a problem with a large tank and incorrect level readings, I could see the echo trace on my lap top and it showed two return echos. One was from the surface of the liquid The other which was the larger, was from the surface and then was being reflected from the top of the tank, back to the surface and then to the transducer. The top of the tank was a wonderfull reflector.

I have had the same type of problems with radio signals where a reflection from a hanger door been moved became stronger than the signal that I was using to check the kit I was working on.

The combined width of the face plate, and casting, and mounting bolts just would not fit. Not even near.

I am building the 2" Fowler road locomotive using a Myford 7 and a Tom Senior mill

The wheel rims do not need any machining. Only the final gear and the fly wheel were too big. I machined the final gear in at work and cut the teeth at home on the mill. The fly wheel I did in a rush at work an I am not too happy with it. No more access to work machine any more but it will sort out.

The diff was machined out of iron disks from M-Machine wounderfull service at all times.

All the gear cutters came from Ebay.

Go for it, the problems have a way of sorting themselves out as the build progresses

Just measured my legs, but I cannot hold the tape measure far enough away to read the numbers (imperial). Back to square one, my arms must be shorter.

Thank you for the help. I find it harder to see things on the floor, therefore the floor must be further away. Problem solved. the legs are getting longer. I will measure them each week and record the results.

My arms are getting shorter, or my legs are getting longer. Trouble reaching my feet to put my socks on in the morning.

Please advise.

I have used auto tune on some large VSD,s and motors, the function allows the VSD to learn the characteristics of the motor, it is done on initial initial installation and does not have to be done again, I hade some very strange results when I did not run it first, mainly the motor ran but did not develop any grunt. I think this parameter goes under several different names. Not all VSD,s have this function ABB drives did as far as I con remember, been out of it for a while. Again it could be a function to use in a PID control situation, if so nothing to worry about when driving a milling machine.

Rebuild an Aga, or a Blakes marine toilet, you will be glad of whitworth spanners. You will also require a stiff drink and some pills as it will drive you insane.

Do not think it was better run under goverment or coucil control. I joined working in the water industry just after privitisation an I had never seen so much worn out rusty uncared for plant in my in my life. Down west they solved the problem by putting it in the sea. The council took the water rates money and spent it else where.

I am building a 2" Fowler engine, the belly tank is secured to the horn plates by two brackets. All the band around the boiler does is suport the weight of the front of the belly tank. Not going to move any where.

Thought it was poor at showing just went on in such a works. I worked on the dirty side for 20+ years.

There was no mention of the mess the operators could get in when things went wrong and became covered in the

'product'.

No mention of the endless battles of the fitters have, maintaining the continual break downs on the mechanical side.

No mention of the instrumentation controlling the plant and how tightly the discharge it monitored.by the environmental

agency

Altogether a light weight programme

Use M-machine metals very good service. cannot fault them.

You have answered your own question, screw a slug into the threaded hole and it saves you buying a new spring every time you remove the tool post. You will remove the tool post more times than you expect to.

Cheers
