Been sick the last few days and didn't get to mess with the Swivel base for the Big Palmgrens. . Got it done today. This is the Big *** 8" $90 Palmgren Engineers Vise in the pic. It's sitting on a Eclipse brand swivel base for their version of a 8" Engineers vise the EVM8. It comes with bolts and lockdowns.
This base will work for both the 6" and 8" Palmgrens.
Albeit with a little finessing!! This took less than 30 min total to adapt this base.
Out of 4 bases I ordered, this is the only one that will come close to fitting to the huge base on the palmgrens.
The first picture shows how much material needs to be removed from mounting slots on both the 6 and 8". About .090 give or take. I used the base itself to eyeball the clearance needed. I used a right angle grinder with a 4.5" grinding wheel for this operation. It made short work of it.
You will need longer carriage bolts to utilize the swivel lockdowns. They are metric.
I could not find any metric carriage bolts in short driving distance. So I ran through the swivel lockdowns with a 27/64 drill and tapped them to 1/2-13". The metric thread was close to 1/2-13 so it was a easy job I then used 2.5" long 1/2-13 carriage bolts and grade 8 washers for the lockdowns to finish off this project.
The machined pads that are on the bottom of the vise are sitting on a flat surface for all four corners just like a Record made swivel base.. There is a lip on top of the Eclipse base that I may remove in the future to gain more purchase on the bottom faces. For now it's fine.
The Eclipse part # for this base is EMVSB-8
The cheapest place to get it in the states is
Zoro.com. I've purchased 2 from there. They come out of Canada

so you won't get them for about a week and a half.
Anyway..pics
