dsc_0018.jpgThe Bridgeport is now ready for work. Over the last month it has been stripped, painted and rebuilt. Just trammed the head and made table covers as most of my workholding is done in the vice. Must get hold of the missing label that goes on the front of the belt housing.dsc_0017.jpg

Nice looking mill looks like you have worked well on it. It just needs some work to do. Hope it keeps going and keeps producing parts for a long time.

Very Nice. I have just installed a Gate PBM-2000 which is a Bridgeport copy. Perhaps I had better make some covers for the table.

Neat idea for the drill chucks etc on the side of the knee. My main power panel is located in that spot.

Nice job, but I can still see the bottom of the suds tray.

That's wrong.

Please fill it with swarf directly...

I am green with envy. That Bridgeport looks fantastic. I would love to own one, one day. Enjoy!

Nice job. Done quickly too.

Way covers are great but one piece ones can be restrictive.

I made mine as 4" (approximately) fold up sections from offcuts of the plastic shower wall / ceiling panels sold by the likes of IPSL et at. Simple tape hinges. Loads of stock so throwaway when they get tatty (must do some more!).

But I have two vices and often work direct off the table so a bit of flexibility in the cover system saves a lot of cleaning down.

Re the shower wall / ceiling panels. Ace in the kitchen as they are wipe clean, I like them everywhere else in the house but the finish and patterns might not be to everyones taste. Great cover-uppers for a "getting old, needs to come down ceiling". Saw to length, hook the tongue in the groove and bang-bang-bang with the staple gun beats the heck out of mega-mess from pulling a 70 year old ceiling down! Stained wood moulding glued round the edge finishes the joint to the wall nicely.

Hi all, Many thanks for the nice comments.

The way cover is made from a sheet of rubber tread material (off cut from the well deck on my boat) and is fixed at the top by a T shaped bracket made from 3mm alloy plate. This plate is fixed using the existing bolt which acts as a stop for the Z axis upward travel. The bottom end is fixed using the existing rear saddle wiper cover. So no new drillings required to fit and it allows the Y axis to travel back as far as the vice allows. I'm happy with the amount of travel as I'm just in the process of fitting a 3 axis DRO and would have needed to limit rearward travel to stop the scale on the back of the table getting squashed.

I will use a wider piece of material to shield the Z axis scale allowing the reader head to mount on the knee and thus leaving clearance for the oil port. Most people seem to turn the scale with the head to the rear and use convoluted bracketry to move the head, or mount the scale on the knee, all to ensure that swarf does not enter the scale (i.e. have the gap facing to the rear). I think preventing swarf getting anywhere near the scale is a better option. I've experimented with fly cutters, face mills, drills and mills on steel, alloy, brass and cast and I'm certain I can stop unwanted bits getting where they are not wanted.

Clive, If you meant the table cover (which I'm sure you did cheeky) I too have found that limitation. My plan is to build two piece covers which slide into each other a bit like the original covers between the saddle and the knee.Then I can shift the vice around a bit and keep the table T slots free from too much gunk. Probably over engineered but I'm still like a kid with a new toy at the moment.
