Wolf Jahn Cross slide reassembly.

[way2wyrd]

So i bought this beautiful wolf jahn cross slide for my lathe.  The plates move well and the cranks are smooth. I removed a bit of surface rust on the tool post which turned out well and will see how chrome polish works on the actual plates.

When it got here it was disassembled. I know how to attach the plates with the pin as ive seen that done.  My question comes in regard to the point/arrow. It was out and I'm having difficulties reinstalling where the plates would sit flat together.

There's a pin the obviously goes into the hole in the top plate.  The issue is that the arrow seems too wide to fit in the groove.  It just alost fits but before I get the tap hammer out I wanted some opinions.

Thanks

It looks like it is supposed to be a press fit - however the pin does not look to be aligned with the hole?

The hole in the slide for the pin looks to be exactly half way between the edge of the circular counterbore and the outside of the slide - but the photo from above with the pointer in its slot has the pin somewhat too near the centre bore?

Try using a straight edge across the slot and making a very light scratch across as an alignment guide (or use engineers blue to allow a visible line without scratching the metal), then try fitting the pointer again, with the pin centred on the line?

 

If it's still too tight, I'd try clamping in a vice, with some kind of packing to avoid marking it with the vice jaws, plus a block over the pointer to avoid bending it. Use a bit of scrap brass with a hole in it for the top, it that protrudes.

yeah the pin alignment i originally thought would put the back of the arrow at the back of the counterbore but you are correct it needs to be offset towards the front. 

using a sharpie to mark the pin alignment is a great idea i hadn't thought of. Easily removable.

the vice jaws are a good idea as i can control the pressure while press fitting it in.
