DIY Co-axial Shooting T-REST

[Vasko J]

Congrats Vasko, it looks really nice! Svaka cast, izgleda mocno

Thanks,
Hvala, hvala

Vasko,
I googled the Harrison 600 vertical mill, and although it may have been available in the US, it appears to be quite popular in the UK and NZ. How old is yours? Is it similar to the old Bridgeports (that I grew up with)?

Have you tried your T-Rest yet?

Thanks again!

Alex

Yep, yep, good, good old Bridgeport...

My Harrison is a nice machine, not too large and pretty quiet. It is pretty old but when I got it from the UK it was in an unused condition and it is still...
The problem was that I did not have the tools, accessories and attachments for it and I spent a lot of time and money to complete the necessary.
For my modest projects it is quite good for now..., although having in mind my plans and the new fun projects one CNC mill would be very very useful to me

T-Rest saw the light of day a few days ago and I didn't have time to tried it yet ... but I hope it will be these days, considering that the competitions of our small LR Balkan league will start at the end of the month.

Cool project....and nice work.

Thanks,
I tried...

Vasko,

Only one word... WOW!

 

[PhilKeil]

Wow, nice job. I would love to make one. Plan to watch the videos.

Thanks, don't hesitate to try...It's possible

Thanks Paul,
I started during the last winter and after 3 months T-Rest sees the light of day.
Most of my time I spent in defining the correct dimensions and proportions because I did not have any sample or specimen of this kind of shooting rest or any input parameter...making it even more "fun"
If you decide for this "fun" project, I am at your disposal..., from this distance (Montenegro-European Western Balkans)

Vasko

Vasco,

I will definitely be picking your brain on the coax assembly and what components worked out best for you. I may have to start sketching something up for the next winter project. Keep us posted on your likes and dislikes, if you have any to share. Beautiful job on the rest!

Don't suppose you have any design or drawing dimensions you wanna share or sell. This would be a cool project to knock out while I gather more equipment.

Hi,
To be honest, I didn’t make any technical drawing because I’m not actually educated for something like this. I am a lawyer by profession and just a big fan of Long Range shooting and reloading and Mechanical Engineering is my hobby (I am a self-taught machinist). What I have noted and dimensioned can only work for me and I am quite sure that no one else can manage it, as my buddy Kemo says "...no one on this planet".
Certainly, I am definitely at disposal for any help for everyone interested in my T-Rest (only I know trough what I pass last few months )

 

[sharp.shooter.ser]

Lol if you are willing to let it go over the winter I can have it drawn per dimensions and specs. Kemo can arrange it

amazing

T-Rest wouldn't want to go....not even with Kemo

How many hours and how much in materials do you think it cost?

 

[BORGY76]

So the handle is for your side to side ( X axis ) if the barrel were considered to be you Z axis. Your vertical controlled with a threaded rod if I remember correctly? Sorry, YouTube keeps crashing my phone so I'm unable to go watch again. So XZ are both run on linear bearings?

If it is you would not be able to move it at an angle. Spherical bearings probably.

Here in the Western Balkans for material (without consumables tools) I needed about $ 200, no more (I didn't keep financial records) and I have some material left for that amount... but in the US you can go cheaper I'm sure.

It took me 3 months. I spent most of my time defining the exact dimensions and proportions because I did not have any sample or specimen of such a shooting range or any input parameter.
Now with my T-REST sample I think 15 working days will be enought for "hand made it" (without CNC)

I’m not sure I understand correctly because of my humble English.
If we look as a 2D system, coaxial "heart" with handle has horizontal X and vertical Y fine motion on ball linear bearings.
It can also be quickly and roughly vertically Y controlled by threaded rod or better said gear rack.

It appears that it won't work on a diagonal if I've looked at it correctly. It appears that you need to make a Y adjustment and then an X adjustment or vice versa. Am I reading it wrong?

As a master machinist, wow, very nice work!!!
