August 19, 2017: Engine
The Engine assembly is very straight forwards as per instructions.
The only modification to do on the engine is to remove from the back of B01 the resin as per image 013. This was overlooked by my manufacturer, they didn’t upgrade the CAD file.
Do the same to the other side see image 014.
How back of part B01 should look once modified see image 015.
Engine nearly complete, all the’s required is ignition leads and plumbing.
Other side of engine.
August 18, 2017: Body
Now for the body.
- It’s a good idea to reinforce part number B05 with a strip of 4mm x 3mm styrene or any other material you have. Gives the body rigidity see image 001.
- Attach B05 to body making sure it’s flush with the rear edge. when you are happy smear some 2 part Araldite to the inside to give it strength. Once Araldite is dry smear some super glue to the joining edge between the body and B05. This will give it a good seal so you can sand and have it ready for painting see image 002.
- Now attach A5 to body, instructions item 12 say to attach at the time of attaching body to chassis but I found it better to do it before. Make 5ure when attaching A5 to body you leave a step see image 010.
Attach part number A1 to body as per instructions item 15 see image 011. Rear suspension D07 and D08 will be easy to attach once body is on chassis.
Attach A2 and A4 to body as per instructions item 16 see image 012.

August 13, 2017: Mercedes W125 assembly guide.
First item are the wheels. Read first before you start.
- REMEMBER, FOR BEST RESULTS FOLLOW CAREFULLY AND TAKE YOUR TIME.
- Sort out the turned Aluminium rims for the 2 front and 2 rear wheels. The inner rims are the same for front and rear, outer rims are also the same for front and rear. The center rims are different, wider for the rear and thinner for the front.
- Attach the 3 rims for each wheel as shown on the instructions, Item 10 for the rear and Item 11 for the front.
- I found it best to attach the 4 rims with Blue Tack onto a stick and paint them with your preferred paint. See image 001.
- The real car wheels were painted silver and I found the best paint after many attempts was the Vallejo Acrylic Metal Coat 77.701 Aluminium. I sprayed 3 thin coats and let it dry overnight, don’t forget to prime the rims with a metal primer, I used MR. Hobby Metal primer.
- Carefully remove the Photo etched sheet with the wire spokes from it’s bag, prime with MR. Hobby Metal primer and spray with Vallejo Acrylic Metal Coat 77.701 Aluminium. I sprayed 3 thin coats and let it dry overnight.
- I found it best to do one wheel at a time and much care should be taken to make sure that everything will work out prefect, the wire spokes are very delicate. Carefully cut the photo etched wire spokes Pa3 and Pa4 of the sheet. As per instructions Item 10 place Pa4 over Pa3 making sure the notch in the center lines up. Apply Super glue with a tooth pick on the outside edge, do a quarter at a time making sure the spokes are central between the each part. See image 002. Carefully do the same for the remaining 3 quarters, a small drop of super glue is adequate.
- Carefully remove the 4 hubs C05 and C06 from the sprue, prepare them and attach them to a stick with Blue Tack and spray them with Vallejo Acrylic Metal Coat 77.701 Aluminium.
- Attach C05 or C06 depending rear or front wheel you are working on with a small drop of super glue, make sure you line up the notch on the photo etched spokes with the hub C05 or C06 see image 003.
- Carefully insert the spokes to the inner rim, this will be slightly larger in diameter. Best to have a clean sheet of paper on a flat surface, lay the inner rim facing down and then insert the spokes. When you apply a little pressure to the hub of the wheel it will fit accurately.
- Once done insert the center rim, again pick either the rear or front. The whole assembly should click in place see image 004. The center rim should be flush with the inner rim. When you are happy with this, apply super glue to the contacting surface of the Inner and Center rime. Please be very careful not to press on the spokes as they will bend out of shape.
- Now follow the same procedure as on line 7. except use Pa2 and Pa1. Carefully apply a drop of super glue to the outside edge of the hub and attach the outer wire spokes Pa2 and Pa1 make sure you line up the notch on the photo etched spokes with the hub.
- Have the inner face of the wheel on a flat surface on to of sheet of paper and then attach the outer rim by carefully pushing it over the wire spokes and push the outer rim till it goes together with the rest of the wheel. It should click in place. Once in place and you are happy with this apply super glue to the joining faces of the center and outer rims see image 005.
- Once glue has dried, place the completed wheel on a sheet of paper, inner rim face down and carefully manipulate correct tire on. It’s a good idea to practice this before the start of assembly. See image 006 Make sure you do no apply any pressure to the wire spokes as they will bend.
Completed set of wheels for the Mercedes W125.
