Tim,

Because you were creeping up with the drills, you could have wacked the 10mm thru it. The surface finish would easily clean up with a bit of hand lapping.

Bit late now, but you will know next time.

Nice start Tim. I think this one is going to turn out well for you!

Good to know for future reference :thumbup: thanks Bogs.

I do have to say that reaming this depth in brass was not as much fun as I thought it would be. Even though I snuck up with drilling it up to 8.9mm before using the 9mm reamer, it still would bind up and jammed up a couple of times. So I introduced my friends, the low speed pulley, the 3-in-1 oil can, and the "ream a little-back out a little to clear flutes-ream a little bit more". The only stuff that I've reamed before was thinner stuff, so it took me a bit to get used to getting the feed right.

Thanks Eric, It's great to be challenged with a more advanced build than the elmers #25. It feels good to be stretched and to learn new techniques.

And I have to say a really big Thanks to Bogstandard for taking the time to put together and write the plans for this, and then to make them available for free, that is truely great, and I really appreciate your time and effort that you put into this.

I reccomend everyone should download and read the plans, even if you are not considering building it the plans are very easy to follow and explain techniques that could apply to many other builds.

So we got a little bit more done today, I say we because Stefan (spynapples) was over finishing off his airgun-trigger part, once we got it finished he helped me out doing a little more on the Paddleducks engine.

1st of all we started on the packing nuts, we chucked up some 8mm hex brass bar, turned a 6mm section and then threaded it.

Then we parted it off and did the same again.

The only thing that bothers me a bit about these is that, because of the width of my parting tool there isnt much thread left, about 2.5-3 turns on each nut.

Then we cut off some 22mm round brass bar for the packing gland, chucked it up and turned down to 18mm. Then we turned down an 8mm section and put a center drill in the chuck and almost drilled it.

Then Stefan had to go so we called it a day there.

So just a short update, hopefully I'll get some more done over the weekend.
