Changes

[Gene DeLoney]

Finally got around to making up a new block that will accept the rimfire and the PPC barrels.
The old block was 6 in. long and had 4 bolts per side.
The new block is 7.5 in. long and has 5 bolts per side and is bored round to accept different dia. sleeves for the different dia. barrels.
Also made a new mount that locates the scope off set to the left and slightly higher.
Shot it today with the rimfire barrel and the results look VERY promising.

Gene, is the sleeve black Delrin?

Yes it is.
1.750 O.D. / .900 I.D. for the rimfire barrel. I was a little worried that the thickness of the Delrin might be a problem but doesn't seem to be an issue on the rimfire maybe because of the light recoil.
By the way, the sleeve is in 3 pieces each 2.5 in. long for the 7.5 in. long block.

Beautiful machine work Gene. Did you build the rest of it? It rivals Jay Young's work.
See you in Phoenix.

The rail was built by Bob Dodd (RFD) some years back. It came with a V block setup.
I built the bored block and the off set scope mount.
I have a few more ideas to try out and will post pics of on going changes.....for better or worse!
Look forward as usual to seeing you next month.

Really?

Really?

What would be your choice?

[Dave Tooley]

Jackie,
My first choice for material for bushings would be phenolic. Temperature stable.

Dave, We used to work with Phenolic a lot, (Micarta), in the making of water lubricated Rudder Bushings. We don't see it that much any more. The industry has developed other non metallics with better self lubricating qualities.

But I can see where Micarta would be a good choice.

[Butch Lambert]

I have a 2.5"X8.5"X48" stick of Micarta and it could be had at a very favorable price. It is green and I think linen.

GUWA, would you expand on your comment?
