How to install deer fencing in granite boulders?

[DFB]

Definitely need a SDS Hammer Drill!

Good comparisons here

Have you considered going with alternatives to fencing? How about a propane canon, it's set on an adjustable timer, auto rotates, adjustable decibels, can be moved and stored, inexpensive and it really spooks the deer. One would be enough for your 6 acre property if it is rectangular in shape and not going 5'000 ft in one direction. Another idea would be to install battery or solar motion detection with animal sounds as an alarm to scare them away; i.e., prey. Now days you can buy high frequency equipment that will scare away deer and kids but can't be heard by adults. Lots of municipalities install these equipment at troubled areas to keep pest and adolescents away at certain hrs of the day. Focused it on the area you want. If you have solid granite, not crumbling and the rocks are boulder size, immovable by hand tools, then consider using an epoxy like "click-it" (primarily made for military, best product out on the market) to secure U-shaped brackets to the boulders, from there you now have anchoring points for your wire that you can electrify, or use the brackets to secure a post. Use high tensile wire from Kensington out of Pennsylvania, US Made, you will need very few posts in between. Electrify them, to insure deer stay out.

Correction - Kencove (not Kensington), Max-Ten 210 KSI 12 1/2 Guage, min break strength = 1617 lbs, 4'000 ft coil, 105 lbs, $99.75.

When I bought my property I found a lot of ledge, I also owned a horse. Where I couldn't use a tree, I filled two tires stacked on top of each other with a couple stacked cans to leave an open cavity in the center with cement. I then shoved a tree trunk post in each one and put up the fencing.

That's a great idea. If you don't want to drill the rocks, you can get used car tires for free, stack them up as corner posts, fill with rocks or sand that you require from the immediate vicinity. An empty 55 gallon steel drum would work great too.

This reminds me of how we set a couple of power poles in granite in southeastern Manitoba (Whiteshell District) in the mid-'60's. Someone had already drilled the holes in the rock so I don't know what they had used. But three of us set the poles and completed the line work. We used molten sulphur to set the rebar steel rods in solid granite. We heated it with one of those burners plumbers used to melt lead to join large pipes. I found this thread with some photos showing the technique:

It looks like this is perhaps no longer used, perhaps for safety reasons. But it seemed to work well and supported everything fine while we climbed the poles (in the pre-bucket lineman days).

I see they are used in Scotland and it may still be used in the Kenora Ontario area, which is near where I was involved in the rockset.

Visit a nearby rock climbing shop and explain what you want to do. Perhaps someone there could point you in the right direction. They could put you in touch with someone who owns a Bosch drill. If you did not mind the labor a simple star drill would do. I would consider drilling few holes (two) in the rock and bolting a multi-holed post at each location; a labor saver. For fencing duty, simple expansion bolts would work fine. No need to epoxy.

Innovative idea. Might use it where needed to avoid unnecessary digging into rock. Just need old tires.

I think you are wasting your time. I think your goal is impossible.

Hahahah. I just developed an extinct volcano into a prime view property overlooking the California coast, build acres of gorgeous gardens, a pool, a house ... You think fencing is impossible?
No need to give advice like that to anyone! And I am a girl.

Great Idea. Thank you for the link.
