Atlas 7B Dulux re-furb
Hi folks on the weekend I finally started on the restoration of my wee little atlas shaper. I plan on painting it,changing the bearings and re making the down feed screw the original is a 1/2 unc and it's way to course. Here's a before photo and a photo of the scratches in the ram. I got lucky all the ways are in great condition execpt for two scratches on the ram.

Good to see Andre
I'm surprised to see a small shaper with square ways everywhere. The hardest i found was the vertical "adjustment" of the ram ways, as you need to machine the way plates to suit. Mine has huge play vertically, but since the ram weighs so much its only a problem on those monster cuts! All i need is a huge surface plate and i could fix that......
Look forward to the updates.1915 17"x50" LeBlond heavy duty Lathe, 24" Queen city shaper, 1970's G Vernier FV.3.TO Universal Mill, 1958 Blohm HFS 6 surface grinder, 1942 Rivett 715 Lathe, 14"x40" Antrac Lathe, Startrite H225 Bandsaw, 1949 Hercus Camelback Drill press, 1947 Holbrook C10 Lathe.

Ill be looking forward to the update's also Welder, this will be a great project and a very handy machine.
Are you going to use 1/2 UNF for the downfeed ?
That would give you .050" per full turn of the handle or .025" for a half turn, I find it hard to understand why it would have had a 13 TPI thread ?

Yep I am going to make it a unf thread I have no idea why they used a 13 tpi thread but other than that the machine is very well built.

The douglases have a crazy tpi too don't they? Maybe its just something unexplainable the manufacturers did?
John, i imagine the Austo has a 5tpi like mine? makes the 20 tpi Andre is going for sound very fine indeed, actually i think 5 tpi is a bit course, from the little i have done anyway.1915 17"x50" LeBlond heavy duty Lathe, 24" Queen city shaper, 1970's G Vernier FV.3.TO Universal Mill, 1958 Blohm HFS 6 surface grinder, 1942 Rivett 715 Lathe, 14"x40" Antrac Lathe, Startrite H225 Bandsaw, 1949 Hercus Camelback Drill press, 1947 Holbrook C10 Lathe.

Ueee It should have a graduation collar, I can see one in the picture here Atlas Shaper
the graduations on that would give an indication of the thread and welder could make his thread to suit the collar with TPI that is a division of 1000
I reckon 5 TPI thread is needed for the load of the cut on the bigger shapers, ESPECIALLY after I seen your little play session

Scrape marks
How does one go about repairing scrape marks on ways as pictured on that shaper ?
Is there a suitable filler available ?

I never though about filing the scratches I was just going remove the burs and reassembled. I am not 100% but I think it will be painted dark blue.
