I did drill and tap two holes. Struts will still move some. Not rock solid. Thinking about using Loctite on the screws. Just irritating as heck!

Next time drill the hole in a V pattern. Grind the flat stops like normal, and make sure to use thread lock on the set screws. You should not get any rotation with this set up. I hope that will help you for future set ups.

How do you drill a hole in a V. Pattern?

I have always found ways to screw up drilling and tapping, drill bit wanders, threads get easily stripped in aluminum, always seem to end up with ugly left over holes.

I find it easy to blame Robart because they make it so easy to ruin their struts, so. I just don't buy them anymore. It just sounds stupid, they make premium scale retract systems for which they charge high prices, and then pass on one of the most difficult tasks for the customer to screw up.

If ya notice, Tam's stuff comes finished, holes drilled and tapped, extra grub screws.

Bottom line, Robart sucks, I hate them.

If i am going to drill a difficult piece i will try and do two things first.
One.... if possible is center punch it. It does not take much to make a small indentation. You could even use a small nail for this purpose.

Two.... I start out using the smallest drill bit I can. This essentially makes a "centering hole" for the next larger bit. Use sharp bits and at fairly high speed too, like in a dremel. Then I work my way up in size. Might take my three drillings to get to my desired hole diameter.

You have the procedure exactly right. Center punch, then proceed to ruin a bunch of small drill bits while drilling pilot holes. Soft Aluminum tends to ruin drill bits pretty fast and the end result usually ends up with a less than perfect job.

In order to drill and tap holes you need sharp drill bits, a good quality tap, and a fixture to hold the strut without damaging it.

This post was entered to merely get the subject matter back to include electric retracts that have been proven to work. The list is extensive and does not include Robarts.

In my opinion, Robart retracts, mechanical, air operated, or electric are equivalent to Edsels in the modern world of retracts.

Keep a candle next to your drill bits. When you drill aluminum, tap the bit on the candle to lube the tip.
Cutting aluminum with a chop saw? bump the blade with a candle first....

Do you guys mind if I go through this and clean it up a little. For example; delete unneccessary posts that have nothing to do with Retracts?

I agree that you should clean the thread, it would be great if it was only a "comprehensive list of electric retracts" maybe add a note in the op stating discussions about retracts to be posted in a new thread and a link to posted here so you can add a discussion link to each retract set for ppl to discuss those particular sets in.

Wouldn't it be easier to update initial posts with comprehensive info.
The chatter will happen when all more or less has been said and ppl are, well, just chatting.
But OK just straight to business talk if fine too.....

Looking for a beat up set of Changs Sun retracts someone may have for parts.
I did a drop landing from about 10ft when I ran out of power and air.

Anyone know if there are some kind of spacers for the dsr-46 retracts to mount flat on some wood? Trying to mount them on my f22 and don't really have the tools to make spacers for them. Thanks
