Thanks for the offer! I have a couple of kits, and if I survive the first two I'm looking at getting others, so I think sinking some $ into a 1/4" reamer is worth the effort.

Several Regions have held meetups already, but others are being planned or are evaluating the interest. The Ontario GTA West area meetup is planned for Saturday April 26th at Greasemonkeys shop in Aylmer Ontario. If you are interested and haven’t signed up yet, click here! Arbutus has also explored interest in a Fraser Valley meetup but it seems members either missed his thread or had other plans. Let him know if you are interested in a meetup later in the year by posting here! Slowpoke is trying to pull together an Ottawa area meetup later this summer. No date has been selected yet, so let him know if you are interested here! We are not aware of any other meetups being planned this year. If you are interested in doing something in your area, let everyone know and make it happen! Meetups are a great way to make new machining friends and get hands on help in your area. Don’t be shy, sign up and come, or plan your own meetup!
Reamers

Some general advice - but it especially applies to reamers. Be careful buying some of the "round" products on Amazon (and probably others like Ali and Bangood) What some Chinese manufacturers call 1/4" I have found is really 6mm. They seem not to know there is a difference - or just think that close enough is OK.
Related thought - I just bought a few cheap machine reamers in metric sizes to expand my ability to enlarge a hole accurately. A 6.4mm reamer does a good job of opening up a 1/4" hole if you need a relaxed fit.

For Chinese the 1/4 reamer is almost certainly made as metric reamer of specific size. Which is totally fine as inch is fixed to mm.
So that would be 6.35mm reamer. 6.35mm does not seem too "odd" of a size for a reamer. If you got 6mm instead they almost certainly simply made a mistake.

That looks fantastic! I like the different textures/finishes too! I would love to do one of these models, I just have to get a bit more confident...I've worked my way through a few wig-wag engines that function so far...
Where did you find a 6.4mm reamer? I'd like some metric over/under reamers but haven't found an affordable source.
