Another Paddleducks build log
kvom:
As for the reamer, I would have done the following:
1) Chuck the drill in the mill
2) Slide the part's hole onto the drill. This will align it vertically
3) With the part still on the drill, maneuver the table so that the part is flush with the fixed jaw of the vise
4) Clamp the vise onto the part.
Replace the drill bit with the reamer and carry on.
Of course, it's almost always better to ream a hole while it's clamped in the vise at the same time it's drilled.

Tim, you're very good at making a numpty feel like he was actually useful! Thanks for not telling them I messed up one of the valve pistons through not reading the instructions. :thumbup:
I'll try and have the superglue out for the missus to bring home on Wed.
Had good fun anyway, thanks for the shop time!

You know, I'd completely forgot about the piston valve when doing the writeup :doh:
We did make a start on the valve, but just to correct Stefan, it was me who did not read the instructions. We did start by turning down some 6mm stainless to the required 4mm, then at that point we turned the page and read the instructions about drilling the holes / tapping one end before turning down the rod. So we parted off the 4mm section and rough cut the 2 lengths of stainless, chucked one up, faced it at one end and then we drilled the 3mm hole to a depth of 24mm.
That was when the call of the stomach kicked in and we called it a day there.
So if there is a lesson to be learned, always read the instructions/plans through for each part just before you start cutting metal, and read all the way through to the instructions for the next part, just to make sure that you I have not missed out any helpful hints and tips.

You are more than welcome, you are most welcome to come and use the tools and machinery here, and you are even more welcome if you bring scrap bits and pieces :lol:

Tim,
The spools themselves are really about one of the most important bits to get right.
Get good measurements as I have shown how to do, and make accurate cuts. If you need to err on the side of caution, make the cutaway shorter. What you don't want to happen is have both ports uncovered at the same time. It is better to be 0.1mm shorter than 0.1mm longer on the central cutaway. Also, don't chamfer the edges of the cutaways, keep them as sharp as possible, but without burrs.
Just trying to help a little.
