Finished the Pattern for a Dore Westbury base casting, modified the design so both sides are symmetrical about the centre line and a wider footprint. Having to have this cast to complete the build of a Mk1 machine having searched the net for an original base casting without success.

Next job, make patterns for the hand wheel bearing trays for the Table and Cross Slide, incorporate a design change to enable the use of Thrust and Roller bearings for the screws, trying to reduce backlash, fingers crossed.

Nice one Paul but where did you find them and how much.

Robin, the subject has been addressed by David Haythornthwaite in MEW 118 and 119 and I think well worth a read. Bit of work involved but I will be doing the same for my DW.

Sunday morning, just what I needed.

Thanks Sreve

Depends where and how big the damage is, but have you considered drilling or end milling the damage area and machining a steel plug and setting in with Loctite 603 its oil tolerant, then machine the surface and scrape to finish.

It worked for me on a milling vice.

Thanks Andrew,

when you cut the rack, did you follow the suggested method in the book mounting the Quill on a vertical slide? And how did you manage to grind the cutter, with a tool grinder or freehand. It needs to have an inclusive angle of 29 degrees with a tip width of 0.039 inches.

I realy should read the text before I post, sorry.

Andrew/Tony, thanks for the feedback, I have the build instructions and drawings of the rack profile.My main concern is first the grinding of the cutting tool and the depth of cut I should take at each pass. The guidance packing should be placed under the Quill, indicating a full depth cut. Brian

I am in the process of building a Mk1 Dore Westbury Milling Machine and need guidance. I have all the castings, materials, components and the detailed build instructions and drawings.

The problem is this; I have arrived at the stage where I need to cut the rack in the Quill using only my ML7 Lathe. I have bored the bearing housing both ends of the Quill and had no problems at all machining all the other components for the machine, but cutting the rack as suggested in the manual is daunting.

Solution; I would like to make contact with anyone who has been through the build process of a Mk1 and carried out this operation, who can guide me through, and past, the potential pitfalls.

If this part of the build is not done correctly the work may grind to a halt, because replacement material is impossible to find.

Any help and or comment would be very welcome.

Try Hemingway, in discussion with them yesterday regarding castings for a Dore Westbury Mill, they indicated they do have the patterns for the Mk1 Dore Westbury and the Westbury Hacksaw but casting production cost and the call for the kits is limited, so sorry not in the Hemingway product range. >>
