custom felling spikes

[Sierradmax]

Here's how I make my spikes. This is an example for a dual set on a 346xp.

First, I measure mounting locations of the inner spike holes on the crankcase then measure the outer. In the case for the 346, I used the bar studs to secure the outer spike. I use a degree wheel to find the offset in degrees and mm between the inner spike holes & the bar studs. After I input this in CAD, I design a spike profile based off bar height (I have a centerline with the bar studs). I like to get a tooth below the bar & one above.

CAD file:


Printed 1:1 on card stock & mocked for fitment. I was a couple degrees off on the outer spike:


Final Product:


I agree with some of the peoples posts here. Bigger isn't always better. I have made a smaller set for the 346xp that, to me, are more effective and offer more useable bar length.

If you have made, or can make, a set for a 550XP please let me know. The clutch cover has the blind mounting holes for an outer set of spikes but to the best of my knowledge Husqvarna have never released any. The useless little single spike and average filtration are the biggest letdowns of an otherwise excellent saw.

I too like the big spikes, I also put double spikes on all of my bigger saws. I have made them out of old circular saw blades.

Very good material

Lots of teenage horror movies with chainsaws in them, have over-sized spikes on them.

Good to know they serve a purpose in the real world.

Yeah it's tough and cheap if you have them around

Actually they do bog saws in many Australian hardwood species. Ultra sharp spikes tend to sit on top of the bark, bite in once the chain grabs, the spikes then penetrate the bark, and pull the saw into the cut too fast - it's like an elastic loaded saw if you get my drift (hard to explain). Had it happen numerous times on a ported 390XP with some imported spikes from the US (can't remember the name but they were the 5 spike version). Horses for courses and I'm well aware you do need long spikes on certain species that you cut. Threads about this have been posted before many years ago, probably by me
They were also that sharp that they slowed production down by sticking in TOO far!

Matt, you and i talked about this once. i agree that longest point under the bar is a problem for me as well. i prefer the longest point to be no lower than the bar. the AM is making a three point version with the longest point in the middle......only one way to see if it works well, i'll let ya know what i think.

I've made a set for the 562xp and so far, they've held up. I'm not sure the difference, if any with the 550xp but the clutch covers have a similar appearance. the 550xp might be a bit smaller but shouldn't be hard to fab a set up. I have a 550xpg sitting on the bench that's next on the list for fitment.

Loggers like big spikes when working with huge logs (24" dia. and up). It still amazes me at how easily the spikes get bent out of shape. Whenever I service a saw with big spikes, I usually always have to true them back up.

Believe me, most spikes like this are going to get bent by loggers. Case hardened steel might help, but forget about drilling holes into it ex post facto.

I just have dual factory dawgs on my echo cs600 and piltz.....yes piltz large dawgz on my ms360.they help when i'm stumpin.especially those groovy looking maple stump that don't grow anywhere near resembling round and go from say 25" right out of the ground down to 18" or so 4-5" up the stump.add that to cutting a sloped cut on the ide of a mountain side and it kinda gets aggravating.the large dual dawgs help with gettin a bite where one small factory dawg won't or in my case can't.

Verrry old post, but may as well resurrect.

I make dogs to fit a 272.

I am sure those are good products also.
They are steel, however, and fairly high priced for what they are.

Titanium is a novelty, and I don't focus on making mine gigantic.
