Concentricity gauge - made in my home workshop.

This is concentricity gauge, it's a diagnostic tool used for checking the "straightness" of hand-loaded ammunition. If the ammunition is not concentric, you need to find out why.

[@pstewart5443]

That is a very nice tool. Thank you for sharing it with us!

[@Targetmaster1066]

Thank you - I find great satisfaction in using stuff I've made from scratch myself.

[@CmaxArms]

Sir, you never cease to amaze me......Wow.........

[@damiendoyle9948]

Another cracking design. Like the quality of your work.

[@Targetmaster1066]

Thanks Damien - Only happy if I've got a new project bubbling round my head. :)

[@jamie57061]

Lovely work as always Allan.

[@Targetmaster1066]

Thank you Jamie - I will eventually get around to making another small batch of these.

[@vomact1052]

Lovely Job!

Madd Skillz Sir🤘🏽

[@toddb930]

Nicely done. It looks alot like the Accuracy One Concentricity Gauge, including the magnetic attachment technique.

[@DLN-ix6vf]

that's what I thought it was / is !

[@ovenpaa]

I like the idea of the rare earth magnets, cracking job! :)

[@Targetmaster1066]

Thank you David - They come in all shapes and sizes and not too expensive.

[@ovenpaa]

We use them for all sorts of things from holding job sheets to boards, right through to temporary mounting of gauges on machines.

[@Targetmaster1066]

I think they open up a whole new world of design. What about using opposing magnets as recoil springs/buffers in semi-auto .22's or in place of springs in trigger systems or magazine catches.

[@baldfatgit1]

Very interesting :)

[@firebee1093]

Is there a website showcasing your ingenuity and the cost/details to acquire? Several of your items are of interest to me.

[@glennvandenberg3912]

Great vid. Been thinking of making one myself. What type of bearings did you use to run the case in and do they have much run-out in them?

[@Targetmaster1066]

Thank you Glen. I looked at several different bearings and eventually settled on Zen bearings, good quality manufactured in Germany. I tested the gauge with parallel pin gauges and find there's no detectable indicated runout. I also tried the more traditional hardened balls to eliminate this perceived problem but the low friction of the bearings make it much "nicer" to use and no less accurate.

[@dentalight]

Very nice looking work.
Can you tell me where I can source the parts in the US?

[@Targetmaster1066]

Thank you Neal - Unfortunately I can't be much help. This is all handmade, the individual parts all machined from solid blocks of aluminium, the wooden base was cut from a bread board. The small bearing the cartridge rolls on were from Ebay. There are no plans, every one I make is different and I make it up as I go along.

[@rogercummins3588]

Where could I purchase the wheel the contacts the brass to turn it, or did you machine it yourself?

[@Targetmaster1066]

Thanks for the interest Robin - Unfortunately I machined it myself out of 50 or 60mm Delrin, then I machined a groove to take a 3mm "O" ring.

[@vomact1052]

If you ever make another batch please let me know......

[@Targetmaster1066]

Thank you Vomact - I certainly will.

[@dalefine3329]

Very NEAT! I think I asked too much but... Can you provide the drawings of details? I will see if I could make them thru my friends. I like yours better than others! Thanks for sharing!

[@Targetmaster1066]

Thanks for the interest Dale - I've made 8 or 9 of these gauges, all slightly different - I never draw up plans, just make it up as I go along. Here's another in progress at the moment: imgur.com/7sjqxMx

[@roderickformosa2423]

built any new ones since last time? look forward to acquire one

[@Targetmaster1066]

Unfortunately not Rod... But I will (eventually) :) If I make another batch I'll certainly hold one back for you..
Allan

[@roderickformosa2423]

Tnks alan theyre beautifully crafted

[@roderickformosa2423]

Have you built any new ones I can order?:))

[@Targetmaster1066]

Hi Rod - Sorry, not got round to another batch of these yet. Working on several other projects - I'll post a video of new stuff when they are up and running. Most of my time is taken up making the Targetmaster auto-tricklers.

[@Creek_Hunter]

Have you gotten around of making another batch?

[@Targetmaster1066]

Thanks for the interest, but no unfortunately not yet, they are on my "to do" list though - I'm working on another couple of projects at the moment and hope to get another video up shortly.

[@Creek_Hunter]

@@Targetmaster1066 Keep up the good work! Love your videos!

[@Targetmaster1066]

Really appreciate the encouragement - I'll try to improve quality and content...Too many projects - too little time. :)

[@rustycraig7562]

Where did you purchase the wheel?

[@Targetmaster1066]

I machined it out of Delrin and used an O ring for the tyre.

[@roderickformosa2423]

Would you sell one? I like your design

[@Targetmaster1066]

Thank you Rod. I made just five of these - all sold before I'd finished them. I'm doing a dozen different things at the moment but if I get chance I'll do another small batch.

[@roderickformosa2423]

Tnks for getting back to me I would be happy to buy one looks like really good quality. Do let me know pls. Thank you:)

[@signalsoldier31]

I would pay you to make one for me
