Phil,

I was simplifying the action but as you say treat each side separately, there is plenty of room in the central block for a good depth of thread so once the outer end is in line with the outside of the frame it can be screwed in.

The same with the other connections.

I am not yet in a position to complete this assembly but just thinking ahead, I was not able to think outside the box so that was why I asked for help. Now that you have explained the procedure I understand what I need to do when I come to assemble the cylinders.

I will report back when it is completed.

Thank you again for your explanations.

Roger

Phil,

If I understand you correctly you are saying to, for example screw pipe into cylinder twice required depth, then as the other end is screwed into the other side it unscrews half the depth. Both sides then have the same depth of thread.

That sounds like a good method central blocks and pipe work do not get in the way.

I will give it a try as soon as I can and let you know the result.

Thank you for your helpful reply.

I am building a 3 1/2-inch firefly. I have reached a point where I have made all the cylinder parts and I am trying to work out how to fit them to the frames. In each of the frames there are two holes for the steam pipes. The steam pipes are screwed into the cylinders and valve chest.

All the threads on the pipework are right-hand threads I am unable to work out how to fasten the cylinders, valve chests and pipework together and fasten them to the frames. The steam pipes are to go through these two holes in each frame. Could someone suggest a solution to this problem, the only answer I have is to cut a slot in the top of each frame and fit the valve chest separately after having first fastened the cylinders in place.

Hi,

Has anyone used the Apps available for the Ipod/Iphone from the following web site:- www.plaincode.com ?

The "Clinometer" is good for levels etc. and the "Setsquare" is good to set things up on, for example a milling machine at any angle required.

They are also Free which is even better.

Roger
