I'll go into what I did for the "T" track. I used 2mm styrene plastic (about $9 per sheet), and cut it into 9mm and 6mm strips. 9mm for the horizontal and the 6mm for the vertical. I then worked out how long, and where to bend the T track for each run along the barrel. From there I cut a small bit of timber to bend it over for a sharper bend.
I can recommend the Black and Decker heat gun as it works fast and has a fantastic temp range.
Once the T track shows a bit of slack from the heating, I race it straight over to the block and bend it straight down. It cools rather quickly so be careful.
After a bit of trimming and finishing, they slide nicely into the right holes.
Not too bad considering how much they cost...maybe a bit more practice...
So, from there I managed to get them glued on and disassembled the rest for the primer part of the build...
Ahhhh...the scope rail. I managed to make this from some 20mm wide and 3mm thick aluminium from Bunnings. This was easier to make than I thought. Theres plenty of forums with scope rail tutorials, but let me know if anyone wants more details on making this.
Next up will be the final coats of paint and assembly. Can anyone recommend the best finish? Gloss, satin, matt with or without clear finishes????
