Just recently finished another concentricity gauge - I think this is No. 9 I've made over the last 3-4 years, all a bit different.

Very nice, I love seeing home made equipment like this!

Thank you chaps - Always got a project on the go.

Here's another couple of home workshop jobs.

Arbour press and BP revolver press.

BSA Martini scope mount.

Another concentricity gauge.

Love the arbor press and black powder loading tool I don,t suppose you have drawings for them. What material are they made from. I,m guessing stainless if so what grade do you use.

Mostly aluminium, the vertical rods are stainless. Unfortunately I rarely make any drawing of the stuff I make, I just do rough sketches to see if the idea looks right, if it looks like it might fly then I see what materials I have in stock and scratch away.

This is the sketch idea and result for a .22lr adjustable barrel tuner. I've never seen or heard of one that sits between the barrel and a moderator - it works very well. There's an "O" ring in the brass weight to give friction so it stays where it's set.

I do 90% of my work on Sketchup these days. It is saved as a hard copy, readily changed and printed and I can email it to myself for secure backup. I can also export as a .dxf for CNC. The other 10% - well part hand sketches on sheets of A5 and part trial and error on the machine :)

This is why I love my job. We use Inventor which is as good as CAD packages get. And included in our licences is a home use install so I can use it for personal projects too!

Pippin89, not bad, software like that costs a fortune.
