Internal Travel Lock

[Jason Richardson]

Can anyone advise me on the best way to drill the internal travel lock bolts into the turret lid?
I only own a cordless drill and a dremel, so I don't think I can re-create the flat bottom on them.
Do you think filling in a bolt head with putty and inserting it into a countersunk hole would be OK?

That method works fine. I picked up some mill ends. Do not have a mill or even a drill stand. I start the hole with a drill bit, 7 or 8 mm. Not drilling in deep. This gives the milling bit a steady base to start from. Make the hole with the mill end fitted to cordless drill. It works quite well. I have to do some on a tiger so I will post some photos to explain.

Thanks John, that would be great.

Thanks John that's very helpful.

So I take it you can move the smaller mlling bit(4mm) around the inside of the initial "larger"(7-8mm) hole until you achieve the flat bottom effect?

[John Fitzsimons]

yes. I use the bigger drill bit to start with as if you try to start with mill it slides all over the place. Try it out on some aluminium scraps.

Thanks John.
Looking forward to trying this out now.
Cheers

You are welcome. Hope it works for you.

[Jason Richardson]

Success!
The only difference was that I used a dremel to mill out the final part.
Thanks again.

Hello Jason I did the same just used my mini mill , good to see you moving forward so well with your tiger looking the goods for your first build . Dale

Hi Dale, what type of mini mill are you using. I was thinking of getting one and a mini lathe also. No idea how to use one but I can learn.
