Spyderco Pride rescale - Part 3

I've moved on a little bit since the last post and starting this one. The Titanium has been ground down to shape and I've also reduced the height of the spring, almost to where I want it.

So next job is to make all the holes for the 1-72 screws that'll hold the micarta scales onto the Titanium.

A bit of marking out, trying to work out where to locate the six screws. I was undecided on the middle bottom one at this point.






With five drilled, I had a look from the uncoloured side to help decide on the sixth location - hopefully it'll look ok!!


To drill the holes in the same location on the other liner, I used the original bolts as location pins and a hand vice to keep it all together.





Twelve little holes





Then to start tapping - half done here!


The tapping raises a slight burr...


 ..so I used a small but very sharp countersink to just knock the corner off the holes on both sides.


Twelve holes tapped and screws in to check they're all ok!


Next onto the micarta.

One screw in...


...and holding a liner on so that it can be used as a drill guide.


Now what you might notice in the picture above doesn't make sense. The liner is on the wrong side of the micarta - that was intentional. I missed out drilling lots more holes but if you look on the picture below, it shows the underside of the micarta with all the holes drilled.



You can see the break-out from drilling. I didn't want that to be seen on the outside of the knife. Even though I'll be countersinking, I  didn't want to risk it going past the countersink.

So all the holes have been countersunk to allow the 1-72 screws to rest flush with the surface of the micarta. You can see the two test countersinks I did at the top left of the micarta, just to be safe! Once set, I used the depth stop on the drill press to make them all the same.


Right, what next?

Spyderco Pride rescale - Part 2

So again I forgot to take my camera into the workshop to take some action shots - shame as titanium sparks look cool (even though they're quite dangerous!)

Over the weekend I discussed the handle shape with Maarten. Shape A is the original shape but we're going to go for a shape like B so that it's a single curve in the centre. I had said that I was going to test it out with cardboard but this morning I got carried away and just went for it!!






A rough shape starting to form...




Lots more work to do on this side.


However in checking the liners fit, I have spotted a problem!





 I instantly thought that I had drilled the holes in the wrong place so put one of the old scales on but the problem is still there.




I'm going to check with someone a bit more knowledgeable than me on slipjoints but I'm hoping that I can grind the top of the spring down to be flush with the back of the blade.

Spyderco Pride rescale - Part 1


A re-scaling project where I've been given a bit of free reign.

The Spyderco Pride has aluminium scales that are fairly uninspiring and quite different each side.


The request was for micarta or G10 replacements but I decided that I'm going to go a little step further.

You can see the Pride resting on the Brown micarta that will be used for the scales. In the picture below, I have added some extra dots. They are where I will use Torx screws to attach the micarta scales to Titanium liners. The original screws will be hidden underneath the micarta. 


The original component parts.



So I missed out on taking pictures of drilling the holes in the Titanium.
Not too exciting but each hole needed two drill bits & one reamer.
- First use a 3.5mm bit to mark the centre of the hole, using the old scale as a guide for placement.
- Second drill out the hole with a 3.2mm bit.
- Third ream the hole with a 3.5mm reamer
- Repeat for each hole.


Beautifully lined up (but I just realised that I didn't drill out the lanyard hole!)


Next job that seems quite basic but is actually very important is to deburr all the holes.


More later...

Toddy's knife - Part 1

So ages and ages ago, I ran a little competition with the prize being a blade ready to put a handle on, to the winners design.
Toddy won and picked the top design out of this lot:


At the same time as making Toddy's blade, I decided to make some of the others up as well as it wasn't a design I had tried out yet and wanted to play. For some reason I only started three out of the four and I don't know why now!

So one still needs to be profiled properly but I have progressed with the other two, both with bevels and heattreated, with Toddy's being worked on more.

The bottom one is flat ground but I think I may have gone too thin. We'll see!!
With Toddy's I have gone for a convex bevel. I know she likes it and uses it as she has a Bark River Mini Canadian.


I'm hoping that it'll be a nice discreet knife, quick to use but also comfortable due to the full length handle.




That could have been the end of this one (except for taking some more scratches out)
However, because it took me so long to get to this stage, I decided that I would put a handle on it as well (she can make the sheath herself! )

Mary wanted a wood that is native the UK and wasn't worried about the lanyard hole (I'm not too fussed by them either).

So a bit of Laburnum that was cut down from a friends garden more than 10 years ago, some stainless road, glue and clamps...

Then starting to rough shape....



A different day after fondling it a while to decide what needs to go...




The finger groove needs to be really comfortable. It'll make or break this knife. It'll be going thinner yet but I'm taking my time with it.
