Re: ghetto style knife sharpening

I use a similar knife made by Dexter. Looks similar, but the handle is bright yellow and there is a bigger tang to keep your hand from slipping up onto the blade area. It goes for around $12. The...

Re: oil finish on mahogany guns

A cheap, easy, and durable finish is beeswax. I coated a mahogany gun with beeswax in 2010 as an experiment and have been pleased with the outcome. It does require periodic re-application on a...

Re: Slingshot Weapon with pulleys

Pete,

The Barnett fish bazooka is the same concept as the Scope Arrow which is intended to be shot into the water from the shore. A few years ago I had the opportunity to snag one off Craigslist...

Re: Modified rail gun muzzles

Check out the Apnea and Meandros muzzles on this site: https://www.diveshop.gr/index.php/180.html

Re: Roller Polespear worth it?

One I made back in April 2014 based off LePrieur's design. Uses a 3/8" band, the knot can adjust the tension or pre-tension of the band for shooting at close or distant.

Re: Carbon Fiber Gun structures

An ultrasonic thickness gauge should be able to detect the wall thickness if you can calibrate it to the speed of CF, but will only work on relatively flat surfaces.

I've used ground penetrating...

Re: Father of JBL dies

Pete,

Voit made a few gold anodized barrel guns. One I found in the trash about 2 years ago. (First 3 photos) A rather small gun about 34" overall with single piece trigger, simple molded...

Re: Does a magnet affect spear velocity?

Magnets work pretty good for holding a shaft down, but you still need to think prudently about the muzzle design and how the line will wrap even if it's not holding the shaft down.

There is no...

Re: Rubber crumb

How about a fine cheese grater or aggressive grit belt sander on a block of rubber or old shoe? You are likely looking for an EPDM or urethane rubber vs. a silicone based. Automotive rubber tubing...

Re: Advice on repairing an epoxy track?

I'd just buy a sharp chisel or Dremel and make it symmetrical. The track is not doing much there, and the shaft will align and engage in the mech as is (once you smooth it out)

Re: reverse mechs... tell me why again?

Those mechanisms appear to show a roll pin with very thin wall thickness. OK for the trigger stop and coil spring mount roll pin at the front. The roller sear roll pin is what appears troubling.

Re: Has anyone worked on developing speargun sights?

I've put them on a few recent Hawaiian sling builds using hi-vis acrylic. More for the design, but could be functional.
