I’m liking this model.
I might just finish the model then start the real deal all over.
It’s only a hobby

#7485 Model 1874 Camel gun

Posted by Anderson Guncraft on 10 January 2016 - 04:43 PM

This pic was taken yesterday 01/09/16. 1874 Camel in .45-70 nearing completion. I still have the feed hopper to machine. This is the last major part of the gun to be done. Gear blanks are at the gear cutting shop and should be done in a couple of weeks. After the gun is done I'll start on the tripod parts.

I bored the crankshaft holes in the rear frame piece.
Measures good, but can always be adjusted a little if needed.

#8722 Faux Brass

Posted by Sparky_NY on 12 January 2019 - 06:58 PM

Here is a coated aluminum test piece against the real brass housing.     Naturally, the camera does not capture such color / lighting  details well,  it actually matches FAR better than the pic looks.

 

BTW     Polishing then coating the heads of those steel screws to look like brass is in the plan.

#8717 Faux Brass

Posted by Sparky_NY on 11 January 2019 - 01:05 AM

Not machining but material related.   

 

As we all know, brass costs have gotten totally out of hand.    I have been considering alternatives that would look like brass.   

 

About a month ago, I bought a Harbor Freight powder coating system, $60 with coupon.   My main idea was to powdercoat the metal pieces of the tripod when the time comes, probably in black.      Well,  I got to looking and there are 6500 colors/types available from just one vendor (prismatic powders).    They have a "tinted" clearcoat brass that is intended to go either over a chrome color base OR bare polished metal.   I ordered some and today gave it a try.

 

I took a scrap of aluminum about 1x4 , polished it up and coated it.   After the usual baking at 400 deg I was amazed at how much it looks like brass.   How close does it look??????    The aluminum coated piece laid up against my real brass housing matches about as identical as you could ask for !!   Its amazing !!    I would say that with real and a coated piece on the table in front of you, standing, you couldn't tell which is which.

 

I am inside now but will try and get some pics tomorrow.   Don't know how well pics will do justice to such comparisions but will give it a try.

 

Here is a link to the product.       https://www.prismati...ASABEgLKe_D_BwE

 

AND a couple pictures from their website that I would say is a real good representation.

The Casing is off the lathe, faced to length and
bored for the cam blanks. Mounting holes next,
along with the clearance holes for the crankshaft.

#8590 Tap or internal threading tool advice

Posted by maccrazy2 on 15 December 2018 - 10:59 PM

Well it took me three hours but came out pretty well for a first attempt at making a tap. Grinding the tool to cut the threads proved to be a little more difficult than I think it should of been as the threads on the screw are worn throughout its travel. I just need to heat treat it and give it a test cut.

#8588 .38/.357 prototype

Posted by Sparky_NY on 15 December 2018 - 05:15 PM

Got my gears installed and working.   Ended up making a meaty block to hold the crank and gears.    I was thinking that because it mounts to both the recoil plate and the housing it would assist in absorbing recoil.  The back edge of the block comes up flush with the housing and the inside of the rear cover for further recoil support.  

 

I am probably paranoid about the recoil but better to err on the side of caution I figure.

 

Mainshaft gear is attached with a key and slot in the mainshaft which allows about .050 movement each way for headspace adjustment.   A needle thrust bearing is between the gear and the recoil plate.

 

The crankshaft gear is sandwiched between two needle thrust bearings and attached to the shaft with a 1/4-28 long setscrew through the gear and shaft.   The shaft runs in oilite bearings in the block on each end.

 

My homemade gears work great.    Only mistake was I should have put a shoulder on the smaller crank gear for the setscrew/pin.   I redneck engineered it with a shoulder ring spot welded to the gear.   I may remake that gear later with a integral shoulder,  then maybe not  LOL

Start building those and you could end up with free long term room and board.

#8518 New holding fixture I'm working on.

Posted by maccrazy2 on 22 November 2018 - 05:08 AM

I just finished up the base. Just need to clean everything and get it over to the anodizing place. Next up drill the indexers mounting holes and machine the bases to the exact same height. Hopefully I’ll have that sorted out before the base is completed.
