Hullo Calin......nice to hear from you...hope you are well  :beer

The pressure gauge in the lubricator is to confirm to the scale engine/boiler room crew that forced pressure lubrication is available for the engine  :hehe

Have been working on the wheels...an old 1/3 finished set...manufactured new shafts other parts.......purchased a set of paddle blade cast brass supports from Manfred at Elde-Modellbau ...... M2 & M3 Hex Head brass bolts from KNUPFER & assembling with a swag of Chinese brass serrated nuts

More completed on the wheel sets :hammer ......

72 x M3 brass HPGS each end of converted to 1/16" diameter brass tie rods.....56mm long overall
72 x M3 brass insert nuts
144 x M3 brass washers

All assembled OK, however each wheel took a quite a few hours in the lathe to true up each assembly.......the hammering during the riveting process [36 x 1/16" rivets per wheel] created a little distortion of the arms & frames

I am undecided how to complete the final M3 insert nuts locking...will need to talk with Thomas to understand how he completed [grade of Loctite?] this with his Elde-Modellbau wheel set

I am needing to be cautious of the weight...[each wheel now calculated as ~~ 405gm]...so have ordered 36 x D1500-23 KSF e-clips for the actual 1/8" paddle shafts to position and lock against sideways movement [the KSF = bronze material]

So each wheel will comprise brass plate, bronze bolts, nuts & rivets, and Grade 316 main hubs & some M2 SS HPGS....

The 5/32" shafts grade Grade 304, the shaft beatings are 5/32" bore ZZ sealed stainless steel ball races in aluminium plummer blocks

Hullo and thankyou François........

Considering the amount of  :hammer required, I am happy with the squareness and parallelism of the 1/16" diameter tie rods

I am thinking of cutting some wooden spacers of identical length to use as jig spacers when I do the final tighten up of all of the 144 x M3 nuts prior to the Loctite process
