I was literally getting ready to sharpen my spear with a file when this video appeared at the top of my feed. Rob Allen saves the day! Big thanks for the relevant video!
I would not have thought guys would want to see that. We have never been asked for this so, we have never set up a way to do it but...... I will consider it 👍
@@RobAllenSpearfishing Tri-tip seems intimidating having been used to conical. but maybe im completely wrong. my spears are always slamming into rocks too, sometimes at 9 degrees. sounds awful i know. i try to do double taper like when you first buy a shaft but hard to get a factory clean-cut end every time. Maybe its time for tri-tip, even though i do very little hunting without something behind the fish.
I have no drama with a good sharp file. I have restored some very damaged tips from mates shooting rocks and still manage to get facet angles and lengths exact. A linisher/belt sander and jig would be easier though.
Good advice 😎🤙🏽🌺 I thought building a simple jig with the desired sharpening angle that also turns 120 degrees to switch to next phase. But I spend too much time in the water... anybody knows if such a jig exists already?
A bench grinder is difficult because as you see, best to grind away from you but also onto a flat surface. The outer edge of a bench grinder has a radius. If you could mount the bench grinder on its side and use the side of the stone it could work. It is best when you can visibly see the 2 edges against the stone at the same time to keep them uniform.
It would be nice if you can redo this one day for people with zero tools. I mean I live in a condo. I do have a file I suppose that’s all I can do, but certainly can’t get it very refined unless I’m just doing something wrong
@@RobAllenSpearfishing thanks. I don’t have any sort of clamp and often find that is the most difficult part. Could a hand vice grip work? I don’t have one but that’s something I could get
Good day Rob. Any chance you could make a batch of spears for pneumatic guns? I can send over a template for the threaded tail portion. Loving the videos, can't wait to come back to KZN for some soul fishing.
No problem, just need to know the thread. Some I have seen are 6mm metric. We can thread both ends. One problem, being plated, your line slide might scratch up the plating. What diameter are you looking for? We do 6,3mm, 6,6mm, 7mm, 7,5mm and 8mm only.
@@RobAllenSpearfishing Fantastic stuff! I use 7mm, 7.5mm and even 8mm when there's halibut about. Line slides are currently holding up well in plastic and delrin so no worries there. Will figure out a decent way to ship them Northwards (I relocated to Norway many moons ago) and get back to you. Just by chance, I'm currently starting up my own maritime business here - do you need a good dealership for Norway or Scandinavia? I'll do some mad fun promos for your kit!
As long as you do not get it red hot it will be fine. The straw colour is ok. Grind slowly with time between grinds to cool. I have only once tried to re heat treat the tip, did not seem to make a difference but as a one off was hard to tell. In retrospect, the transitional zone between the heated tip and the rest of the spear might be an issue, never tested though.
Wash well and dry with fresh water. Our spears are a trade off against stainless. Stainless don't rust but are no where near as stiff, much more likely to bend and, much higher cost.
Hey Rob I bough one of your spearfishing knifes a few weeks ago and love the design and slim profile but buy the time I got home from using it fir the first time today the knife was covered in rust spots I say I was using it but it was completely blunt the bevels where ground completely uneven and the tip was as dull as a spoon I think there is a problem with quality control where these where made I for one would be ashamed if my name was attached to this knife especially whe its primary function after dispatching fish is safety
I can understand and deal with the rust spots you want to make a blade that retains its edge and is strong but sending them out completely blunt with a rounded tip is disgraceful
