Thread: Marlin Ballard restoration

There's a small island of very nice checkering on the hammer cocking piece
It would be a crime to fit a repop without the patina and these details

So slow and steady and use as much of the original parts as possible

Seeing you making screws reminded me of aa set-up I made a while back to easily make perfect slots in screws. Basically, you mount a drill chuck in a tool holder and use a slitting saw in the chuck. Makes the job quick and easy, repeatable but gives a great job every time.

Don't know about you but I hate to see hand cut screws slots spoiling a good job.

Love what you are doing........ all the best

Looks like a neat system. Recently made some M4 blanking screws as I could only find hex head ones which wasn't in fitting with blanking the rear sight screw holes on a replica Sharps. Cut the slot with a thin cutting wheel on a dremel. Scrapped a few before I was happy enough. Luckily had enough M4 screws to get a few goes at it. They were only about 4mm long too. Fiddly!

Does the slot have a radius in the bottom of it or do you have a mechanism to move the screw up and down?

Yes I just plunge in with the slitting saw, but given the diameter of the saw blade it is minimal. The thing with the drill chuck to hold the screws is that takes just a second to pop another screw blank into place as well.....you could actually do the same with your set up on the mill as well.

Tricky with the very short ones, I would be tempted to loktite them into something bigger just to give something to hold on to, then a bit of heat to remove and a clean up.
