That tower is amazing. I imagine getting the double bends right must be quite tricky.

Frithjof, You are right, the thinner window frame looks better.

My question was HOW does he do all that so perfectly? You answered WHY you do it all so perfectly (your goal is inspiring: "because it usually looks better") A bumbler like me studies your posts in awe because they are way beyond my capabilities. :)

Gentlemen, thanks a lot!

It's quite simple ...because it usually looks better :)

With all my projects, there are always delays because sometimes I'm not entirely satisfied with the results so far or I don't have a brilliant idea of how to turn something into a model.

Then I have to try... sometimes it works - sometimes not quite.

That's what happened to me with the window frame from the old weighing house.

When I looked at the pictures of the prototype again yesterday...

Alte_Waage_Lbg_002 (fspg2)


Alte_Waage_Lbg_005 (fspg2)


Alte_Waage_Lbg_006 (fspg2)



... and compared it with my previous design, I wasn't really happy.

Alte Waage Lbg 84 (fspg2)



The outer frame width appears much too thick!


Today I started an attempt to mill the window kit frame with a 45° V-milling cutter...

Alte Waage Lbg 89 (fspg2)


...during the last milling pass at the bottom left, the thin tip broke off :( 

... grrr....

I had selected a feed rate of 80mm/sec in the 1.0mm thick MS58 (hard brass) with a depth of 0.3mm per pass.

So I stopped the experiment here.


Alte Waage Lbg 90 (fspg2)


The result looks very promising by far... only now I had to order new milling cutters - so there's another little delay .... and time for another project ;)

All of that is very impressive work. (That short, typed sentence looks calm and composed, but my brain is yelling "How does he do all that so perfectly!!!!)

@Rax, @Russ, @Barney, @Bill
Thank you very much!

Almost three years have passed since I rounded the rivets on the portal beams in April 2022:
https://www.finescalerr.com/smf/index.php?topic=1424.600

The fourth, outer portal side wall is still missing.


Träger-Montage 78 (fspg2)



In contrast to the inner vertical counterpart, which is only cranked twice at the sides, the two outer L-profiles are now also cranked at two points, both laterally and to the front.

Träger-Montage 79 (fspg2)



In the following picture you can see the double-bent L-profile at the top.
In the CAD, I aligned the profile in three parallel sections, paying attention to the new length so that the corresponding lateral L and U profiles run exactly parallel to the floor!
The profiles have the corresponding drill holes for the rivet pins in both sides.

Träger-Montage 83 (fspg2)



Two 3.5mm x 3.5mm L-profiles were then inserted into a 1.0mm wide and 3.3mm deep groove in an MDF board with their legs pointing downwards in the middle. Masking tape was used to fix the profiles to the final length during drilling and routing.
The left and right sides with the different 1.2 mm holes were drilled once each in a single pass. The two profiles were then swapped so that the second side of the leg had the correct holes.

Träger-Montage 84 (fspg2)



As before, a new Pertinax stencil helped with soldering.

Träger-Montage 80 (fspg2)



The two legs were initially only bent sideways into position at the respective positions,

Träger-Montage 81 (fspg2)



so I can use the lower part - already completed in 2022 - as a test.

Träger-Montage 82 (fspg2)


Now an L and a U profile still need to be "riveted" in the middle section.

The exciting part will follow next - after the double bending at angles in the second alignment: Have I really determined the respective lengths of the three sections correctly ???

Only then will three (or possibly four) more parts be milled, soldered and the rivet pins wound with the 1.2 mm finishing cutter.

I was unaware that PVC pipe primer was MEK. The stuff sold at the local building supply stores while being water thin is also tinted purple so the inspector can see that the proper procedure was used in assembly. The color will stain anything it comes in contact with including fingers.
