In that pic you have a horizontal line splitting the sketch into two, trim that out.

On that Analyse box you have three results shown, click each one and it will show the error on the drawing which will give you an idea of what is wrong

Geoff you should be able to bring any pipework out the side of the valve blocks. The two long horizontal holes shown here are usually plugged after drilling and teh air/steam comes in from the flat face. but if you just thread the ends of the two horizontal holes you can connect there

Thread: Issue Reading New Digital Viewer

Can't win. People were complaining they could not view with Flash now you start moaning when flash is removeddevil

Maybe as it is a demo you can't get a good print, does not get as far a sprinting for me either but shows the option is available.

I may have been wrong but did not think PM had a print option.I don't use it much.

JES you need to be aware that the Pocketmags VIEWER has never had the option to print a single page so there is no problem at their end.

MTM up until about a month ago used a flash based viewer with the option to print a page that is accessed via this site. This has now been changed to a non Flash player one which at present does not have the print option.

Neil has said that getting the print option added is being worked on. There are various settings on the new viewer, hopefully it just needs a back room boffin to tick the print box.

It's a Flowpaper product and their mag viewer can have the print Icon added to the bar, if you click the image on this page it takes you to a demo mag viewer and the print icon is at the left of the bar.

Thread: Warco Super - Major Vario inaccuracy
16/02/2019 09:03:32

FMES I have also posted above that the photos seem to show the dti being rotated which was not what was said hence my comments.

Until it can be confirmed what test was actually done and how then we can't help much as one result is fixable and the other not.

I would also say if tramming the table as the photos seem to show then don't have the vice sat on one side of the table as can be seen as it WILL affect results.

16/02/2019 08:57:18

Just for completeness this is what I would have expected to see via way of setup when "turning the handwheel" which will give an indication of how true the top of the table is to the dovetails. You seem to have shown photos of teh spindle being rotated as per my earlier video.

16/02/2019 08:04:27

Yes

16/02/2019 07:46:50

I'm not sure of how these measurements are being taken. You said you wound the table front to back and got 0.008" difference. yet looking at the two photos taken from the end of the table the dti has been moved or swung.

This one is taken from the right of the machine as you can see the handwheel bottom left

But this one has been taken from the left hand end as you can see the bellows and DRO wires

So either it has been swung and that is a tram measurement or the photos are posed and don't show slope on the table.

Possibly something in the last photo but not good practice to move the item around when taking the readings, should be laid across the table and then the table wound across. For best results swap slip end to end and take measurements again to eliminate taper in slip.

Also best to get rid of the spring adjuster on the DTI stand

As his advert is under the name "Eric" you must have been able to get his e-mail up to see that his name is Eric Clarke so why can't you e-mail him at that address?

Robert, if you are holding that DTI in a chuck and not a collet that is probably where a lot of your error lies.

As the dti is not being revolved it makes no difference how it is held or on what part of the machine it is fixed to.

Your first photo shows the DTI on something laid across the table but the last seems to show it directly on the table but there is 0.008" difference between first and last reading.

How to add photos here

15/02/2019 20:28:00

Michael,  without rotating the spindle you cannot get a true measure of the axis it rotates on to tell if it is square to anything. The results could have been obtained by mounting the DTI on any stationary part of the machine.

 

Agreed it's not an easy fix.

and checking spindle squareness to table

Not how I read it.

15/02/2019 19:45:40

That does not measure how true the spindle is to the table but shows the tables slopes!

The start of his is how to swing a clock and test the tram

Thread: Submitting Articles to Model Engineers' Workshop
15/02/2019 19:40:27

I usually send Neil stuff by Dropbox but had a bigger article for Martin and used the free Wetransfer which is very easy to use as Neil says and saves me using up the free data limit on Dropbox so will use that in future.

Another Advantage of Wetransfer is the sender gets a message when the person the other end has downloaded the files so you know they have got it which you don't with Dropbox or snail mail.
