Lookin' good, about to embark on building my own wooden track soon so will follow your travels and hopefully learn something along the way.
Happy to share learning experiences. I spent a lot of time routing different radius corners on scrap wood. I also tried applying braid etc to make sure I could do it. I also made my own router bit to do the gains for the braid... can share what I did too.Lookin' good, about to embark on building my own wooden track soon so will follow your travels and hopefully learn something along the way.
Well in tests I felt a 3mm slot worked best for me at a depth of 7.5mm.Nice work! Yes, it would be interesting to see how you have made your own router bit to do the gains for the braid. :thumbsup:
Thanks. Do people generally leave 1mm of space on the inside slot edge so that the braid doesnt lift as Ive read on here somewhere? I have practiced sticking the braid down withThat's looking very nice. I like what you did for the recessed braids.
Thanks for the helpful advice - very kind. The close up pictures are scrap cheap MDF that I'm practicing on. The actual circuit I'm building (first set of pics) is on HD MDF - was quite a bit more expensive and the cuts are cleaner and sharper. Diluted PVA sounds like a great tip - essentially seals the MDF and protects - nice!!Hi
It's not unusual to leave a small gap, it's what the analogue boys do, this allows the builder to paint the slots different colours for id ing the lane..
The mdf lifting is down to your choice of mdf, it looks like it is fluffing up once you've machined it so indicates contract grade mdf, no issue with that but it does require a little more work to get a nice finish, one trick is to paint the slot with diluted pva, this hardens the surrounding mdf but it will all the fluffy buts stand up so it will need sanding before fitting the braid..
Regards fixing, yes good quality double sided tape will work great, especially if the steps mentioned above are taken as this also seals the mdf and stops it bleeding dust which obviously effects the adhesive on the tape...:thumbsup:
And welcome to the forum :thumbsup: and to the world of routed slot car racing :thumb:
Great- thanks.A router bit for doing the gains is available from Slot Car Corner. All of our newer tracks used 3M double sided tape to stick down the braid. The gains must be paintede and a solvent must be used to remove any oil from the braid before it is laid down.
