My DDRT-2 arrived last week and all I can say it  that Paul at Experimental Aero does and awesome job building and shipping this  tool.

  

 If you're using a typical C-Frame tool you may not  realize how much easier (and quieter) your work could be.

  

 It's worth every penny.

Jeff,

  

 Thanks for the feedback.  Enjoy the tool.

  

 Build on....

 I've got a fellow RV(9) builder that loves his DDRT-2.  My only problem with switching over is that if you take away our C-frame, then we've got nothing else to smack during the building process.  I agree, the construction is top-notch and the temptation is very strong to become a convert. 

  

 For those that have spent some real time using both...what are your thoughts?

The DDRT-2( I thinks if he named R2-D2) will sound cool,is a clever and nice machine ,if I have a possibility to improve ,I will made the bottom set much closet to the border ,and instead of square front,only a V shape,that will give a versatility hard to beat.

In my opinion I own to his guy and the cogsdill company a nice couple of hundred. hours save from the project,my opinion only.

I welded up a dimpler with angle iron from an old bedframe.  Finished my RV-6A,  loaned the thing to another builder.  It is on its third airframe, and still works well (loudly).  Much more in the RV frame of mind.

The DRDT-2 is so much better than a regular C-frame.  It allows you to use you other hand to guide your part through instead of holding a mallet.  Just make sure you put the handle in the up position when you’re done using it.  It can really hurt the ribs when you walk into it.  Maybe a bright colored handle would be good instead of black.  Glad to have it.

I have both.  

C-Frame dimpling sucks.    

DRDT-2 ROCKS!    

Thanks again Paul.

I  built a -6 with the Avery C-Frame and am now using the DRDT-2 to build a -10 so  hopefully I can shed some light on this.

  

 First,  my general impression is that the DRDT-2 is superior to the C-Frame once you get  used to it. The dimples are consistent - rivets sit perfectly flush every time  and you never get the ring around the dimples that sometimes show up with the  C-Frame (a by-product of hitting the plunger slightly too hard). It is very easy  to use - effortless enough that my 6 year old daughter helped dimple some of the  larger skins. It is silent meaning you can work late into the night without  aggravating the neighbors, waking sleeping children, etc.

  

 To  clarify the "once you get used to it", I have two recommendations for this tool.  First, make sure it is aligned perfectly. This is easy to do, just loosen the  adjustment screws, install a dimple die into the plunger, tape its mate and  adjust until the shank slide perfectly into the bottom receptacle. Tighten  everything down and double check that the dies slide together with no binding  when in their normal positions. For the depth, set it so that you the dies just  bind, meaning you can't spin them with everything fully  extended.

  

 Second, on the heavier skins (like to fuse bottom skins  some of the spar material, etc) - you need to double pump the level to get a  good dimple. Any skin that is 025 or less can be dimpled in one shot, 032+ needs  a double pump and you should check that the rivets sit flush. There may be other  ways to dimple the heavier skins but this is what worked for  me.

  

 To  summarize, you can build a perfectly good plane with either tool. For me, the  investment in the DRDT-2 was well worth it.

  

 Hope  this helps and I should add that I have no affiliation with Experimental Aero -  I'm just a very satisfied customer.

Fellow DRDT-2 owners or perspective owners,

  

 Tom was very kind in his assessment of the DRDT-2.  

  

 If you set the ram height so that the dies slightly interfere (vertically)  with each other you will not have to "double pump" the tool.  I can assure  you that you can dimple all the thicknesses if you set the ram height correctly  with out ever having to "double pump".  Just set the height and dimple, if  you get a "witness ring" around the dimple then you have a perfect dimple.   The witness ring is not a dent but a surface mark left by the dimple die flat  face contacting the alclad surface.  

  

 I provide instructions for setting the tool up and adjusting the die  height.  It only takes a few minutes of setup to achieve great  results.  If anyone has any questions about the tool or the setup, please  email me at info(at)experimentalaero.com (info(at)experimentalaero.com).  I  would be glad to help in any way.

  

 Sincerely,

  

 Paul Merems

I have both, and have done part of a 7A and am working my  way through a 10, and you could not pry my dead fingers off of the DDRT-2, this  tool set into my workbench is as much a time saver as a pneumatic squeezer. This  tool falls into the category of don't use it or you will buy it. It is smooth,  quiet, and gives a better dimple in my opinion, the reason I say this, is that  it greatly reduces the risk of creating an extra hole, because it is a smoother  action to dimple, rather that a smack with a mallet. You get the same fish eye,  without the risk.

    I took the idea of the DDRT-2 a little further. I  fashioned a C-frame that approximated the DDRT-2 design with one major  difference. I had a special adaptor plate fabricated that would allow me to  insert my pneumatic squeezer. I had a hardened extended length shaft made to  account for the extra thickness of the adapter plate. When put together and  using a pneumatic foot switch I am able to easily dimple a 4' x 8' sheet as the  throat depth is 25". It takes me about 5 minutes to attach the squeezer  to the adapter plate.

  

     I am able to use both hands to guide the panel in place  and I can produce dimples at the rate of 30 - 45 per minute. This thing has  worked beautifully for me and has cut down on the time and noise associated with  this process.

I bought just the frontend of the dimpler while I was in the U.S. and my

uncle constructed the frame.

The plans are great and the Dimpler works perfectly fine.



Check it out some construction pictures in the tools section in the

builder log menu
