Definately a scrapyard challenge

**motoxy** · 08-05-2012

A great big thanks to Michael for machining my z plate registers for me. There has been some progress recently. I have started making the x rails and will get some piccies as soon as I can.
Hows this for an interesting way of losing business. I went to my blacksmith with whom I have concluded about £10,000 of busines this year to make me my base. He wanted £200 which was reasonable. Then I went in after a couple of weeks to check on progress he had not started it but thought that it would not matter as it was just for my 'hobby'. Grrr

Looking good Bruce, looking very good indeed.

had to baby sit an 8 year old tonight. Brilliant someone with the same engineering awareness as myself. So we set up the rig as a temp and checked a few things out. Definitely going to have to do a bit of light shimming but all in all........who am i kidding there is quite a bit to do but it is all doable. One of the bearings is loosing its balls so that will eventually have to be replaced. But I have to say it is all very exciting.

Thats most of the metal bashing completed know. All thats left is brackets to connect the x screwnuts to the gantry and mounts for limit switches. Gues I will have to start on connecting the electrics now. This is the bit that I am not confident about so a bit more reading of old threads and a few stupid questions, as usual.
The y motor has had its mounting made after this picture was taken.

Just looking at them X brackets Bruce how are you going to mount them to the bearing plates with that big overhang from the plate which the rails sit on.?

It's looking good thou getting very close to fire up time.!!!

I will send you a dwg and you can tell me if it will work.

It Lives!!!! Well z and y are working. I have the material at last for the x ballscrew brackets and the limit switches are on their way. The e stop is connected through the breakout board but I think that the external relay for the power to the spindle may be in order. Pictures when the brackets are finished.
Its not pretty but I love it...said the same about the kids

We x y z all working and tolerances not bad. Tied a pen on and drew a line on x and y and seems good using a square.

But I have a bit of a problem with one side of the x axis. As it moves across one side starts to make a noise as though it was starting to bind up. Does not do it in the reverse direction. I have loosened the rails to allow them to move but makes no different. could be the bearings may have been knackered being put of and on the rails as it was built. I have a spare set to try. Disconected and pushing it there is no problem. It probably is the rail/ballscrew tightening.

Have to wait till the weekend now but promise some pictures or maybe video soon.

Cannot believe its been 3 weeks!! Today I decided to swap over the ballscrews but leave everything else as is. The binding sound now comes from the other side and yes I think I know the problem. You may remember that I thought it was a good idea to take a ballscrew apart and see how they worked. I think that I may have not found all the balls and that this is the cause of the problem. So I shall have to get another ballnut and try again.

Water pipes are connected and basically just limit switches to fit.

I have fitted a drag chain on the x axis and I am getting another for the y axis. Some bracketry for that and we are almost ready.
