Drilling PVC pipe

[bbofpp]

I have come up with a device to repel deer from eating trees, bushes, shrubs, veggies etc. And it works - I just don't know the spacing or recharge rate yet. (No, it is not a gun!)

The problem I have encountered involves drilling holes ~3/16" dia. holes in 1 1/4" - 1 1/2" pvc pipe.

Can someone recommend a particular type of drill bit or technique that will drill a clean hole without leaving any residue around the hole?

My drill bits are old so perhaps that is the problem.

Doesn't matter if you have old tools (drills) as long as they are SHARP

Driling round objects you will get better results placing it in a V block and

making a pilot hole or dimple prior to drilling.

Actually if I remember correctly there is a different grind on drills for plastic, I will have to look it up.
But just use a standard drill bit and then de-burr the hole.

In plastics of all kinds ,i use a step drill ,h.f. Cheapest place ,works great!

Thanks folks!

I've never heard of a step drill - learn something new every day!

Looks like there is minimal residue remaining.

I'm curious about the deer repelling. What's the deal?

someone want a pretty garden BUT do not want to harm the wildlife

I use a brad point drill for PVC and wood as they do not slide off where you want to drill.

My device is simple and it works! Basically a section of PVC pipe, end cap, and bottom cap, with holes drilled all over. Fill with your favorite deer repellent. If liquid, fill with absorbent cat litter first. I use Milorganite which is pellitized sewage sludge from Milwaukee! Then hang on trees/shrubs or rig a pole near your hostas or day lilies. I refresh every month. (Patent pending - lol). I have seen deer come up close to a tree and then leave because of the scent.

Milorganite is NOT a registered (with EPA) deer repellent because Milwaukee does not want to spend millions to get it registered. Word of mouth says it is a deer repellent and it is true. It is marketed as a fertilizer and available here in GA at Ace, Lowe's, and Home Depot.

Thanks for the suggestion on step drill bits. I went to Harbor Freight and found them along with a stepless variety. I bought a set of 3 stepless bits for less that $10 and they work amazingly well on PVC. I adjust the diameter of the hole via the drill press.

I'm Glad they worked out for you ,up there you need something to keep the deer away ,I hunted that area, plenty of deer ! Good luck ! Carl

Carl,

The deer here are pathetic small animals because there is not enough food for the herd. They destroy landscaping like you wouldn't believe. We live in a gated community and they have decided to thin the herd every year; they take out upwards of 100 each year in an attempt to keep the existing herd healthy. I can't keep up with the demand from neighbors for my device.

I can believe that,two of my son's worked construction building that area years ago ! Red top mountain state park has the same issue,as well as very nice subdivisions near wooded areas all protected and Home owner association ruled. All have the same damage,some now allowing bow hunting only ! should be a good Market for You !
