First bit of turning done....
Need two of these.
This was my setup for getting the shoulder length right. This and the carriage stop.
This looked kind of iffy to me, but was ok taking 10 thou doc passes.
Fits the side plates like so but with the top half milled off.

A bit of a fitment test reveals...
The swivel shoulder is a tad too wide. I measured 0.026" above what the plans call for. Need to do something about that before milling the top half off.
Had a bit of a shock when I discovered the knurling wheels fit rather loosely on the 1/4" tool steel wheel axle provided. The wheel ID's look to measure 0.261" (6.63mm)
@Aliva did yours fit like that as well

Have you checked with Doug Gray? Maybe the wheels you got aren't quite up to snuff.Had a bit of a shock when I discovered the knurling wheels fit rather loosely on the 1/4" tool steel wheel axle provided. The wheel ID's look to measure 0.261" (6.63mm)

Exactly- you don't want to re-size the axle to fit bad wheels.
How many sets of wheels are included with the kit?
You'll likely want several sets (different patterns and TPI) eventually so having a tool that will accept off-the-shelf wheels will be important.
LMS wheels are $6USD a pair.

I just measured a couple of my LittleMachineShop knurler wheels - the bore is .252. Slightly wobbly fit on the axle, which is likely what I'd want...but not .010 oversize.
Axle is just under .250 - I just measured the end and it was .248.
BTW, The LMS wheels are .373 a.k.a. 3/8" wide.
I'm waiting for @Aliva to respond before contacting D. Gray.
I like dealing with LMS but don't like what they charge for shipping. KBC sells knurling wheels as well.

I've bought several times from LMS. I agree the shipping is expensive. But, it seems to me (and I've done a bit of checking) that LMS is simply passing on the cost of shipping via USPS or courier.
KBC- 5x the price, plus excessive shipping costs.. Not an option for me.
Swivels are done now....
Two swivels ready for a trim on the mill.
50% off the top and a little off the bottom.
One gets drilled through 5/16" the other threaded 5/16-24. Sourced a real nice 5/16-24 tap from @Tom Kitta (Thanks Tom!).
Done and Done. Next up are two spacer pins...

Na, that's an Osbom Blue Wizard HSS Spiral Point Tap I sourced from @Tom Kitta. Tom figured it might be UK made. Very nice.
@PeterT The cotter pin is for tightening/loosening the tap handle adjustment. It binds a bit in places. I usually remove it when tapping.

I have a few of those blue wizards. They are nice.
This is really funny @YYCHM . Thanks for the laugh! Those F#&$@g things always stick and bind and come loose too.
I typically use a small punch or a junk Philips screwdriver. Most people throw them away after the tip gets mangled. My bride is a professional screwdriver tip mangler. I scoop them, grind the tip to a point like an awl (they are usually already pretty pointy) and then put them in a special drawer to be used for times like this and other tasks.
I like your multipurpose cotter pin thingy dingy - balance, tool keeper, torque wrench (bends when proper torque is reached), aesthetic enhancer device......
Yes mine were also sloppy. I would have thought the fit should be tighter. I inadvertently ordered a metric kit so I attributed some of the clearance's to metric imperial conversion.. I have other knurler wheels but the axel bore is too large for the kits axel. I'd have to make a couple of stepped axels in order to use them , and I'd have to disassemble one side in order to fit the larger axel. I did purchase some 12mm HSS rod so I may do it in the future.A bit of a fitment test reveals...

Nothing too exciting today.....
Two spacer pins.
Pins are tapped 10-24. Plans called for two bind holes but I drilled all the way through and tapped from one end. I hate tapping blind holes. @Dusty Note that my finely tuned speed balancer is removed
No tap casualties today
Turning the shoulders.
The pins fit the arm plates like so.

Did you glue your arm plates together in pairs and gang drill/ream them as one per the build notes? Using my mill DRO on each plate, I ended up with one spacer pin hole that was out by a smidge and had to re-drill the two arms spacer pin holes as a pair.
