DMS L1000 Dimensional Drawings?

[pbahorich]

Just to add some more info..

I put some more thought into this..
how about..

For 38mm DMS motors
1/4" Pipe Tap
1/4" pipe plug McMaster https://www.mcmaster.com/44705K383
5/16 - 18 Tap
"F" drill bit

For 54mm DMS motors.
3/8" pipe Tap
3/8 Pipe plud McMaster https://www.mcmaster.com/44705K384
5/16-18 Tap
"F" Drill bit

How strong is it? I made up a test rig..

It was easy to do and seemed secure enough.

Awesome approach Tony! It looks like you just solved a problem on my latest project.
Based on your experience, do you think this would be an adequate shock cord mount on a 38mm minimum diameter (thus fairly light) project?

Based on my indepth scientific rigorous testing...



Yes.

Does this bolt through a bulkhead or will only the motor ejection well take the recovery forces?

I do something similar with the commercially-purchased thread adapters for CTI 54mm motors. Works well but I have a bulkhead to take both motor and recovery forces.

I'm considering using a 54mm DMS motor in a minimum diamter-type situation. It's for a competition that doesn't allow experimental motors-- does modifying the charge well on a DMS this way make it experimental?

According to Aerotech, no:
