welding steel base or just getting aluminium extrusion

I did say to myself i would stay away from this thread.

That said, I do not like to see people getting quotes like you have for your plates. I have not read all the new posts ive only glanced over them. Plus i have no looked at those quotes in detail but its not right. I know roughly what you require as i have made parts for several forum members router builds in the past.

As mentioned they simply do not want to do the job or your drawings are asking for a lot and thats reflected in the price. Small jobs like this are agro for most company's and they charge you for that agro. Your drawing and the details on them will have a large bearing influencing the price. Some of the comments people have raised, i have said and others have said before and they are totally valid. I think its something most new people do not appreciate and it only sinks in with experience.

As the guys have said, you can do your plates long hand and of course has worked for many on here, in the same breath many choose to get them done outside.

I do this kind of works for people at a fair rate because i know the problem you can encounter with pricing. I like to see people doing these projects because it keeps Engineering alive and the knowledge base alive, if you guys cant do these projects, it dies.

If you want me to look at your plates please send me the drawings in either basic 2d dxf or dwg of if 3d in stp/step format. Be prepared to have your drawings scrutinised and alterations asked to be made. But please remember Anything i have said in this thread to you is for your benefit, even though you may see it as criticism, thats probably true for many other that have made comments also. Just to be clear I do not need the work, I have more work than i know what to do with at the moment, so work like this is done when my normal workload is reduced, so you have to wait until i have the time, but this means you get a professional job by someone who has been in the engineering sector (hand on) for over 35 years.

The offer is there. I'm not an ogre and i do not bite, but realise Engineering is a very straight talking trade. It has to be or we would never get anything done.

Thats kind of you mate and you were never in the wrong in the first place or did i ever discourage any of your advice i was just simply trying to avoid welding and go with aluminium but that soon changed lol. I have a few alterations of my own yet so ill sort those out and send you the files if thats ok with you.

Been thinking about how i am going to square the gantry up and thought of an idea using the method used below (watch from 2:20)

i know that method won't work on mild steel box section but what if i used epoxy resin on the side and wait for that to fully cure which will then give the side of the steel box section a really flat surface and then do the method in the video? i would need to do this before welding the top rail beam to the frame off course.

what do you think is it over the top?

The way I see it is that all he is doing is aligning the rail to the same as the ali profile so if the ali is bent so is his rail

It sounds like you need to invest in some tools such as a straight edge, engineers square.
I attached one of the long X rails using a straight edge to get it straight, then it was easy to space the second rail from it. Once you have the bearings fitted and a gantry cross beam attached you can feel if the bearings are tight at any point in the travel and make adjustments to the second rail.
Here's how I squared the rest up; http://www.mycncuk.com/threads/6565-...5217#post55217

read through your thread mate and i have a better picture in mind now so thank you, after reading about your problems with the bk12 bearings is this something i am going to run into when buying from zappautomation? mine will be the bk15 and bk17 not the bk12.
